Apollo’s Experiences

After six years of writing, I am finally closing this weblog. It has been an enjoyable and powerful learning experience for me, and I appreciate those of you who have joined me along the way. The journey will continue.

If you want to stay updated on my current pursuits, please visit lesterleung.com to see what I am currently working on.

Thank you again, and please stay in touch.

Previously, I discussed the merits of the ClamCase, an innovative and useful keyboard case for the Apple iPad. Of all of the higher end and pricier keyboard cases, it definitively remains one of the best options available for the production of written content on the iPad. During the past seven months, I have written numerous admission, consult, and progress notes every day I have worked in the hospital, and I have additionally written weblog posts and numerous e-mails. I often had a hospital computer open to an electronic patient record while having the iPad open to a new word processing file which would allow me to type notes and read simultaneously. Unlike a laptop, the iPad with a keyboard case allows for instantaneous access for quick tasks at the bedside and while rounding (such as typing in an order in tablet form with one hand holding the device and the other hand tapping the screen and typing) while also allowing for comfortable word processing and reading. The combination of the ClamCase and iPad 2 essentially replaced my old laptop (a previous generation of MacBook of the black plastic variety) except for the occasional Photoshop task or for iTunes file synchronization and backup.

However, there are a few important disadvantages of the ClamCase which may or may not be generalizable across the product line. First and foremost, the battery life of the device is variable. Initially, I did not have to charge the keyboard for days at a time, but about five months into its lifespan I discovered that it was losing its charge during the course of a day’s work. After some weeks of experimentation, I have not found consistent behavior of the battery in response to overnight charging and roughly comparable usage each day, leaving me with some degree of anxiety as to whether or not it will keep its charge during a particularly busy day of consults and admissions. I suspect that this is the result of me not treating the battery correctly, but most people do not maintain good battery charging practices which makes me wonder how often customers have difficulty with the battery for this keyboard case.

There are a few other additional small and surmountable issues. The case is heavy: the weight of the device essentially doubles the weight of the iPad. The four protective pads on the keyboard side of the case which elevate the keys off table surfaces when flipped into a video viewing mode quickly lost their adhesive and tore off easily. The keyboard additionally has very nice laptop-style keys, but some do become slightly sticky with time, sometimes causing the keyboard to produce a string of repetitive letters which sometimes would require exiting from an app to interrupt. Over time, this has become a more frequent occurrence. Lastly, on a purely cosmetic level, my white version of the keyboard case very easily stained on the bottom surface within a week of ownership.

In summary, the ClamCase has been an incredible boon to my productivity on the hospital wards, but after seven months my particular device has aged and is starting to run into difficulties. Some user reviews have commented on issues with maintaining the battery’s charge and not being able to trust the green/amber indicator light. If I had assurance that the battery issues has been fixed, I would certainly purchase another ClamCase, but in the mean time, I have started to look into alternative options.

The third year of medical school is a pivotal experience in the lives of training physicians. In some ways, it is one of the most difficult years in training, besides intern year. In this series, I will share lessons I learned as a third year medical student and my experiences teaching third years.

The third year of medical school is the most confusing and disorienting year in the process of training to become a physician. While the first year of residency (intern year) has traditionally been the most exhausting and demanding (emotionally and physically), this year continues to lessen in intensity as the field attends further to the tolls and dangers of sleep-deprived trainees. However, the third year of medical school, if anything, is increasing in difficulty. While the responsibility and activities of interns is centered on patient care activities, the purpose of the third year clerkship is variable and highly dependent on the fickle expectations of residents, attendings, clerkship directors, and medical school curriculum designers. These expectations are unfortunately frequently in conflict with one another and include the following activities:

1. Learning the science of medical management (e.g. pathophysiology, clinical presentations, differential diagnosis, treatment, prevention, etc.) – through lectures, reading, teaching on rounds, the workup of individual patients, and tutorials

2. Learning the art of medicine (e.g. developing relationships with patients and their families, interacting with other physicians and hospital staff)

3. Learning “roundsmanship” and team work (e.g. operating as a member of a physician team)

4. Assisting with patient care (e.g. reevaluating patients, scheduling followup appointments, calling primary care physicians, calling subspecialty consultations, performing minor scut work)

5. Presenting to and teaching the physician team (e.g. learning about a subject and giving a short presentation on attending rounds)

6. Learning a broader standardized curriculum designed by the medical school that encompasses topics that might otherwise be missed between individual rotations (available in some medical schools)

7. Learning how to manage a continuity clinic (available in some medical schools)

Unfortunately, these expectations are often not explicit, or students do not know which expectations to prioritize. Accordingly, it is easy for a reasonably intelligent student with good intentions to fail during this important stage of training due to lack of flexibility, poor insight, and a lack of assertiveness. To guard against this, I offer a brief review of the most common pitfalls that third year students face:

1. Not being present.

The most common and devastating mistake that third year medical students make is to become invisible. In many schools, the clerkship final examination (the Shelf exam) may account for as much as 30% of the final grade. Having spent every year of schooling prior to this learning from books and taking tests on paper, it feels most natural and most safe for medical students to dive into the review books and Up-to-Date in order to desperately try to learn the vast amount of information that they might encounter on their clinical rotations. However, they may fail to account for the remaining 70% of their clerkship grade for which the majority derives from the evaluations written by residents and attendings that work with the students. They also fail to realize that most residents and attendings actually like working with medical students or at least feel some degree of responsibility for their education. This mistake typically manifests as the student venturing out of sight of the residents in order to read a review book in a quiet space. (At the very least, if a clinical service is quiet, the student should ask her residents if it is okay to find a place to read so that the residents know where she is and what she is doing.) Out of sight, out of mind. Once the student removes herself from the vicinity of the residents or attendings, she is no longer is available for the minute-by-minute pearls of wisdom, the observation of how patient care is coordinated and carried out, and the opportunities to engage actively in patient care as new issues and crises arise. Also, the tendency for residents is to write positive evaluations for their students, and being present provides more material to write about while being absent leaves the resident with little to say in favor of the student.

This pitfall is becoming more difficult to avoid as many medical schools redesign their curriculums in such manner that they are spending more time in the classrooms and away from the patient wards and their teams. The most common complaint of residents and attendings is that these new curricular changes result in the students never being around. Accordingly, third year students have to be very careful to cultivate expectations and let their residents and attendings know where they are or where they will be at all times.

2. Being late.

One of the crucial aspects of ensuring one’s attendance is to be on time to all regularly scheduled meetings. This usually isn’t a problem for most students, but again, students who spend more time away from their residents are more likely to be left behind when work rounds, attending rounds, or teaching sessions are shifted from their usual times.

3. Failing to learn something taught with emphasis.

In general, most residents like students and want to see them succeed. Furthermore, on a more self-serving level, students that perform well reflect positively on their residents (as teachers and role models). Residents will use different strategies to help their students perform well in the eyes of their attendings. The most obvious manifestation of this is a resident rehearsing a verbal presentation with a student for attending rounds. The resident will often point out key details for the student to highlight or describe a particular way in which the important information should be conveyed. Unfortunately, some students do not pay enough attention to these explicit rehearsal or teaching sessions. I have too often seen clear evidence of disappointment and disapproval on the faces of senior residents when a student fails to convey important historical details or examination findings or when he botches the presentation structure. While it is not always reasonable for a student to be able to remember everything advised by his residents or to be able to perfectly recite a script handed down by his resident, it would behoove him to be extremely attentive when a resident sits down with him to prepare for a performance. Similarly, when a new skill or concept is taught with emphasis, this becomes a marker for improvement for the student; failure to internalize this new lesson accordingly is detrimental to his subsequent evaluation by that teacher.

4. Being too proud.

Third year medical students are smart: they have clearly achieved excellence in order to make it to this stage, and their proximity to their recent preclinical coursework and Step examinations provides them with a wealth of book knowledge. However, most third year students have minimal amounts of clinical experience and little awareness or knowledge of how medicine is actually delivered. While most third year medical students are aware of this fact and accept it with humility, a select few have difficulty accepting the advice, moulding, and criticism that inevitably comes from residents and attendings. Everyone has room to improve, but not everyone is willing to change. These students unfortunately develop a shell that blocks out criticism and advice, discounting criticism as the product of a resident or attending that “had it out for me.” Unfortunately, these future physicians are also the future recipients of law suits and disciplinary action. Given that most residents and attendings are saddled with excess responsibility, it takes a lot of activation energy to produce constructive criticism, so advice or criticism given is rarely fictitious.

5. Lacking confidence.

While some students fail due to pride and overconfidence, most students trend in the opposite direction: they feel like imposters in a new and alien environment. Bombarded by questions from their residents and attendings, the habitual answer of the overwhelmed is “I don’t know” as it would seem to be the easiest and quickest way of cutting short the torture of feeling helpless and unknowledgeable. Students cope with this in many different ways (some more maturely than others), but typically the best recommendation given to them by residents and attendings is to commit to an answer or decision and yet still remain flexible to learning and changing.

6. Sandbagging or upstaging a fellow student.

At my medical school, showing off and upstaging fellow students or residents was called “sandbagging,” as though one were physically dropping a sandbag from offstage onto an unsuspecting colleague. The most common form of this is when a student answers a question directed at another student. In the stressful environment created by the wards, students all too often feel pressure to perform and look smart in front of their residents and attendings, and this can breed distasteful manifestations of competitiveness. This tendency is unfortunately fostered by some residents and attendings when they don’t direct their questions at individuals. Nonetheless, trying to look good at the expense of others inevitably reflects very poorly on one’s character as few people would want this type of person as a colleague.

7. Being unkind or cruel.

Lastly, students sometimes too easily pick up on the bad habits of residents and attendings. In particular, residents and attendings will occasionally remark unfavorably, joke, or complain about other people (who may be obstructing or causing detriment to patient care) in a private setting when students are present. However, residents and attendings have gained experience and training in tempering their feelings in such manner that it does not affect their interactions with these other parties; these expressions behind closed doors are, in some ways, safety release valves. Many students, however, have not learned or developed these skills and balancing measures. Students then may sometimes actly rudely or unkindly to others as they “side” with their residents and attendings. However, this type of behavior is never acceptable at any level of training or practice and should be guarded against at all times. One of the most important tasks for all physicians is to bridge gaps in understanding with patients, families, and other staff members (e.g. nurses, technicians, therapists) in order to lead and direct the best care possible, and the avenues by which this may occur are obliterated once rudeness and meanness color the interaction.

Fellow residents, what mistakes have you seen students make? What advice would you give to them to avoid common pitfalls as third year medical students? What measures should they take to succeed in becoming excellent physicians?

In the first installment of this series, I discussed the challenges faced by those learning the art and science of medicine, which is to say, everyone (or at least, everyone who is still willing to learn and adapt to the growth and evolution of knowledge in medicine). It is the uncertainty and the complex mechanism by which knowledge changes that necessitate that physicians actively organize and seize control of the ways they learn. Additionally, medicine is a high stakes endeavor, one in which accuracy and precision of information are paramount, and one in which a common mantra is “trust no one.” As such, individual physicians need to establish a fulcrum across which to balance different sources of information and learning. The fulcrum, in my opinion, is the physician’s notebook.

What do I mean by “notebook?” The notebook can be any means by which a student, resident, fellow or attending organizes his or her thoughts. In most cases, this is a written medium which will allow the user to either write, draw, or type information as a means of immediately aiding the storage of memory in the brain and providing a visual map by which to trigger the accessing of memories. This medium should be portable and easily accessible or it won’t be used. Finally, the notebook should be expandable, as the duration of time during which a physician must learn is limited only by lifespan (unlike a notebook used in grade school or college for a specific course). Here, I describe three potential methods that one might use to seize control of one’s learning.

The Moleskine aka “Token of Nostalgia”

The most common method that physicians use to take notes are physical notebooks. These are typically small enough to fit into the breast pocket of a physician’s white coat, often the only pocket with a standardized size across various white coat brands (the side pockets vary greatly in size). In my imagination, the “Golden Age of Medicine” is populated primarily by well-groomed, male physicians who mostly look like Don Draper except that some have more white hair and most are alternating between business suits or long white coats. Nestled somewhere between the penlight and fountain pen rests the Moleskine, a thin leather bound notebook. The company that has the trademark for the name Moleskine has advertised this little notebook as being so much more: in describing the many famous and brilliant people who have jotted down ideas and drawings on its pages, the Moleskine is somehow supposed to inspire brilliance in the rest of us. This notebook fits so well with the traditional culture of reverence and nostalgia within Medicine that it is found in most if not all medical school bookstores.

These little books are useful for their portability and easy accessibility. Furthermore, they require only a pen and (at least) legible penmanship. Notebooks are generally cheap, though the premium brand-name Moleskines usually cost $8-12 each (varies based on size and merchant). Of all the methods of taking notes, this one requires the least amount of startup time. However, all pen-and-paper solutions have serious disadvantages. Perhaps the most prominent is expandability: all paper notebooks are limited by the number of pages available, which means that the notebook will at some point reach its maximum capacity and become a static entity. In this situation, it remains a useful resource for referencing and memory augmentation, but it no longer has the ability to help one grow one’s knowledge base or chart that growth. Furthermore, notebooks require good handwriting: most physicians have atrophic penmanship which is worsened by fatigue and the prevalance of electronic medical records. Paper notebooks also require exceptional planning skills in laying out an effective organizational scheme prior to starting the notebook, otherwise accessing information in the notebook becomes an exercise in random searching. Lastly, if lost or misplaced, a paper notebook is gone forever and cannot be easily replaced.

Personal Experience: Throughout medical school, I used Moleskine notebooks to take notes and by the end went through at least three. I was frustrated by the lack of growth capacity. Accordingly, an alternate solution I tried revolved around the “Pocket Medicine” series: the portable book is actually a small binder, and a few stationary stores actually carried extra lined paper inserts that matched the size of the printed pages. I thought this was an elegant solution as it allowed me to take notes and “insert” my knowledge into the handbook. Over time, this expansion capacity was still not enough, and my fear of losing the notebook prompted me to seek out other solutions.

The iNotebook aka “A walk in the clouds”

As iPads and iPhones (and to a lesser but still considerable degree, other tablet computers and Android phones) become ubiquitous throughout the physician population, the possibility for new electronic methods of notetaking grows exponentionally. When I was a third year medical student, iPhones and iPod touches were still uncommon, and pulling out one of these iDevices in front of an attending on rounds was still considered rude and taboo. However, there is now a well-developed ecosystem of medical apps and resources available for these devices that make them useful for information acquisition in the clinical setting. While there are still some concerns regarding the ability of electronic devices to distract physicians from clinical care duties, the overwhelming momentum is towards the acceptance and adoption of portable technologies into medical practice. Furthermore, medical schools and residencies have discovered educational and clinical training value found in these devices, or at least they are willing to invest money to buy these devices for their students and residents with the expectation of educational potential.

With regards to serving as “notebooks,” the iPad and iPhone, particularly as a pair, are a potent combination. In addition to providing storage and reading capacity for electronic textbooks and papers from research journals (think of the numerous e-mails one receives everyday with an attachment to some review or study), the iPad additionally services as an effective content creation device with the appropriate peripherals. Many people find it difficult to use the glass keyboards of Apple’s devices, and few would argue that typing performance on the glass keyboard can match a physical keyboard. Accordingly, a Bluetooth keyboard is an essential add-on, and numerous elegant solutions have been developed including the Clam Case and Logitech’s Keyboard Folios (solar and standard), most typically increasing the overall investment by $80-150. With these keyboards, the iPad effectively becomes a “netbook”: a laptop with a slightly smaller keyboard (which might impeded some people with big hands), smaller hard drive, and longer battery life. However, the iPad is much more effective than a true netbook because it does not have the startup latency of laptops: most if not all of the tablet computers activate within fractions of a second and can allow one to start typing seconds later. In addition to allowing rapid access to a typing interface, many apps on the iPad and other tablets allow for alternative forms of note-taking: drawing with a finger or stylus, a mixture of drawing and typing in flow charts, and recording audio.

Unlike paper notebooks, notetaking on a tablet computer can be organized and reorganized in a much more malleable fashion. The initial planning stage is less important because information can be readily modified and moved, a feature not present in paper notebooks (there is no readily accessible “copy-paste” feature in the analog world). Simple text editors allow for the creation of innumerable text files, while more complex cloud-based notetaking programs often include content search capabilities, tagging (by keywords), and nesting of files within folders.

Where does the smartphone fit into this? If the smartphone uses the same operating system as the tablet computer, often shared applications can also share data, particularly if one uses a cloud-based storage solution such as Dropbox, iCloud, Microsoft’s SkyDrive, or Google Drive. Accordingly, if one doesn’t have the tablet available (or have the time to pull it out), one can still access all of the same files on the smaller screen of the smartphone (which most people will carry around all the time). This reduces the time required to access notes and more closely approximates the time it would take to flip through the pages of a paper notebook.

There are disadvantages to the tablet computer-smartphone solution as well. First, this solution is expensive: both tablet computers and smart phones cost hundreds of dollars (an iPad, iPhone, and Bluetooth keyboard will probably cost the user about $1000, not including the monthly service fees for the iPhone). Secondly, the data input is reliant on the larger device: typing on an iPad Bluetooth keyboard for the average computer user is likely to be nearly as fast as on a full-sized keyboard, but this requires that the user have a flat surface on which to rest the device. Practically, this means that the user needs to be seated or standing at a counter, such as at a nursing station or using the height-adjustable table at a patient’s bedside. This also means that the user needs to carry both the iPad and keyboard with him or her into the clinical setting. While there are some people who have modified white coats to include iPad-sized pockets, this may not be the most comfortable solution. For physicians that normally carry brief cases or shoulder bags (e.g. Neurologists), carrying a tablet is not an issue. Thirdly, this solution is energy-based, so battery life becomes a consideration. However, iPads and iPad-compatible Bluetooth keyboards generally have exceptionally long battery lives.

Personal Experience: This is the solution that I use at this time, and quoting the late Steve Jobs, “It just works.” I use a Clam Case with my iPad 2 to type my notes. I carry the iPad in a Fossil city bag which fits both the iPad as well as my various diagnostic tools in a non-bulky fashion. I use DropBox as my cloud-based storage solution with Elements as my simple text editor for notes (which is fast, has folders for organization, and keeps my files accessible instantly without an Internet connection on my iPhone, iPad, computer, and on the web on the Dropbox site). I use Papers for handling journal articles, iAnnotate for other PDFs, and Kindle and the iBooks apps for medical textbooks. I generally pull out my iPad/Clam Case during conferences and lectures to take notes, and when I’m on clinical duty and need to check something I pull out my iPhone to quickly access the notes. In my case, the additional weight of the devices is justified by the iPad’s additional uses on the wards and in the clinic: I also use my iPad/Clam Case for writing progress, admission, consultation and clinic notes, and while rounding it is additionally useful for placing orders and checking labs and imaging test results. A laptop, even a small one, would be more cumbersome for the ward-specific tasks (placing orders, checking the electronic medical record while standing/walking), and most do not have the equivalent battery life or short activation latency.

Of note, there are a variety of other methods of using a smartphone and a tablet. There are several cloud-based note taking services such as Evernote, Notability, SimpleNote, etc. For me, I wanted a service that would allow me to access some version of my notes off-line on any device, so a DropBox based solution was the best for me.

The Collaborative Notebook aka “WikiMedicine”

One idea that I have reencountered is the collaborative notebook. That is, a centralized website where several individuals within a field can post and edit files or pages and pool together a considerable amount of knowledge and learning. One example of this that was recently presented to me is HemOnc.org, a wiki-style site that serves as a resource and quick reference for hematologist-oncologists. On the site, one can find chemotherapy protocols, comparison charts between various medications, and references to the primary literature used to guide the design of protocols and selection of medications. This is one such example of a free, non-subscription based site that can be created by physicians for physicians for the storage, growth and dissemination of practical knowledge.

One major advantage of this model is that knowledge can grow rapidly when it is shared. The collaborative effort brings together information much more quickly as each individual is contributing information and is exposed to a different set of patients, different literature, and different perspectives. Another advantage for a web-based solution is that the information can be accessed and modified on a variety of platforms, including on the computers in a clinic or hospital as well as on personal devices such as smartphonese, tablets, laptops, etc. This information can sometimes be automatically backed up to a physical hard drive so that it is not only living in the Internet ecosystem.

This type of model also has unique challenges. Collaborative sites by necessity require more moderation in order to monitor and regulate quality of information. Web-based solutions require an Internet connection which surprisingly can be hard to find in the wireless dead zones of various hospitals and medical schools. Also, websites sometimes require hosting fees and sometimes minimal knowledge of programming (or at least managing basic website types such as wikis and weblogs).

Conclusions

These are only a few methods by which one can keep a notebook as a physician. Regardless of one’s choice, the main objective is to help one take control of one’s learning and the shaping of one’s mind as a complex diagnostic system. This is an important step towards gaining more autonomy as an individual clinician and more effectiveness in treating one’s patients.

The Context

Today, one of the our attendings gave a solid overview of the major families of dementias. With the skills of a talented and effective instructor, he queried the audience of residents and students to help him fill out the content of a table designed to help differentiate between the presentations, test findings, and treatments for the different types of diseases. He was able to keep the audience actively engaged and participating, but at one point he asked a question that was met with silence. I volunteered the answer, and he turned to me, somewhat surprised that anyone knew the answer. I explained (that he shouldn’t be so impressed): he had mentioned the answer in a previous talk given several months ago, and I just happened to have a set of notes from that discussion open on my iPad which I was annotating and expanding with the lessons learned from today’s talk.

While it’s not so impressive that I was able to ascertain the answer, impressing someone was not the point for me: the fact is that I had that information and was able to quickly access it, even if it wasn’t readily accessible in my own brain’s memory bank without the assistance of my notes. This raises a major question for lifelong students of medicine: Is it better to try and store as much information in one’s memory as possible knowing that there will be limitations on the amount of information that can be remembered, or is it better to store some (perhaps a large proportion) of that information somewhere it can be easily and quickly referenced? If secondary storage of information is worthwhile, then should clinical information be trusted to a few easily-accessible resources (e.g. a pocketbook, online medical search database) or should it be digested and recorded into a personal notekeeping device (i.e. a notebook)? To approach these questions, we must first understand the nature of knowledge and how it is gained.

The Student’s Dilemma

While we would like to think of knowledge learned as being the truth and that truth is an absolute, for better or worse the learning of medical knowledge is not this simple. Since medicine is based on scientific principles, there is a constant effort to strive for refinement of knowledge towards the best approximation of the truth, but in the mind of a humble scientist there is also the necessary acknowledgment that a better or more truthful explanation may arise to refute his or her prior claim. Simply stated, medical knowledge changes, evolves, and hopefully improves with the advance of medical science. Nonetheless, there is also the knowledge derived from practical experience (or story or wisdom) that enters the learner’s mind in the form of a “gospel” taught by more senior physicians. In many ways, this information is equally important and perhaps carries equal weight because this information is based on direct encounters with individual people that have the full force of a clinician’s mind reviewing the entirety of their unique cases. Nonetheless, something that is gospel must be preached (with strong language, without wavering, and lacking an acknowledgment of uncertainty), and one only has to preach when there are those who do not believe what is being said. In other words, truth does not need to be questioned, but this does not fit the description of anything in medicine. As such, physicians and patients alike must live and function with great uncertainty regarding what is known, what is not known, and whether or not what is “known” is actually meaningful (or “truthful” as charted against a constantly changing measure of what is true).

I will give an example here: I remember either a Neurology attending or fellow once explaining to me that the mild weakness found on ipsilateral limbs in a patient with a unilateral stroke could be explained by involvement of the fibers descending in the anterior corticospinal tract (which travels ipsilaterally and does not cross in the medulla). This descending fiber tract contains somewhere between 10-20% of the corticospinal tract fibers, varies in size between individuals, ends in the thoracic cord, and likely provides innervation to muscles of the neck and upper limbs. Anatomically, this explanation seems to make some sense. I asked another senior Neurology attending this question in a different patient with a similar presentation, and he stated definitively, “It never happens.” In perusing various Neurology textbooks, I cannot find any information corroborating the first explanation. The traditional textbook that most clearly addresses this question, Neurology: A Queen Square Textbook”, states “Of corticospinal fibers, 10% remain uncrossed, their neurones of origin outlining an ipsilateral somatotopic map, a point of little apparent clinical significance.” Why then, does this fiber tract even exist? There are some studies that suggest that the presence of this “accessory” pathway may aid motor recovery from lateral corticospinal tract damage as in stroke [1] or spinal cord injury [2].

A common response among learners to these conflicting messages is to give up. The tendency is to lose faith in attempting to achieve the ability to “know.” Accordingly, many choose to defer to those who do “know,” or at least believe they do. The appeal of following guidelines stems from this tendency: in theory, a panel of “experts” have pooled together their knowledge and provided recommendations to follow. In this climate of uncertainty, most people choose to follow. But what makes the experts “experts” in their fields? Often they are the physicians, scientists, or physician-scientists who are pursuing active research or have extensive experience with a particular clinical issue. At best, they are driven in their desire to know by the awareness of the incompleteness and changing nature of knowledge and also by the idealistic hope that it is possible to improve knowledge and thus improve the practice of medicine. Ideally, they additionally generate new evidence to contribute to the current knowledge of disease and treatment in the form of clinical trials, updated reviews, case series, and more. At worst, they may be the ones who are simply preaching the loudest and most forcibly.

I, and many others, would argue that this method of learning and practicing medicine is too passive and not sufficiently adaptive. Consulting (to the exclusion of other sources) searchable databases such as UpToDate potentially leaves one’s mind at the mercy of a few opinionated authors. It is not enough to practice medicine as directed by the Cochrane reviews alone. It is no longer enough to practice medicine based only on the anecdotal and experiential wisdom passed down by prior generations of physicians. And it is largely impractical for any individual physician to stay abreast of the latest developments in every field of medicine, let alone in his or her own field with regards to the numerous studies being published every week. Not surprisingly, it is important, then, to find a balance between all of these sources and types of information and information acquisition.

The Notebook

In my opinion, a notebook is the most essential piece of a physician’s armamentarium. It is more important than the stethoscope, scalpel, or any other tool. Why? The notebook represents a projection of the physician’s mind, and no matter the specialty, the physician’s mind is still his or her greatest asset and most effective tool in treating patients. The notebook serves a number of important roles for the physician:

[1] Facilitation of memory encoding

A lot of educational theory and research is based on the many ways different individuals learn, particularly with regards to methods emphasizing visual, auditory, and tactile sensation. Incorporating multiple modalities, such as writing notes while listening to a lecture and watching a slide presentation, is thought to improve memory retention. Accordingly, it helps to write down what is learned, whether on the wards, at the white board, during morning report or noon conferences, or at grand rounds or conventions, as this should help you more firmly implant the knowledge into your hippocampi.

[2] A database of references and the knowledge “family tree” (e.g. lineage)

Because of its origins and the way knowledge works within medicine, the lineage of knowledge remains an important distinction that marks one’s identity as a physician. Since much of medical teaching is based on the experiences of physicians whose careers may last half a dozen or more decades, one’s teachers inspire considerable reverence from the trainees who follow them. However, physicians may encounter several “schools of thought” throughout different stages of training and may find that their own minds are battlegrounds between competing ideologies. Accordingly, I find that it is very important to chart and document from whom one learns a new tenet of medicine (be it a resident, fellow, senior attending, clinical trial, visiting lecturer, clinical trial, review article, textbook, etc.). In the aforementioned example, I cannot remember who asserted to me the notion that damage to the anterior corticospinal tract can result in ipsilateral weakness. As such, I cannot ask him or her how that knowledge was obtained, and it thus holds little water against the assertion of the other attending or my current review of the available literature. If you keep track of your learning and keep references to your sources (e.g. the name of a physician who gave a lecture), it is possible to track how your thinking and understanding of the field evolves over time, particularly when new data is incorporated from new studies or encounters with physicians trained in another school of thought.

[3] A launchpad for inquiry

Sometimes the hardest thing to remember is a question. And yet, as physicians, questions arise in our minds constantly: much of our role as clinicians mimics the modus operandi of the detective. Furthermore, the ingrained abundance of intellectual curiosity is one of the distinguishing features that differentiates physicians from other health care providers. Nonetheless, our attention is also constantly bombarded by numerous competing interests (pages, e-mail messages, patients and families, other care providers, etc.). There are countless times that I had a question I wanted to ask someone giving a talk which vaporized prior to the talk ending and also numerous occasions when I identified something I wanted to look up which I later forgot about. In order to help further develop your own knowledge base, improve the care of your patients, and perhaps even generate questions that might advance the field as a whole, it helps to write down the questions that come to mind as soon as they arise. This can help identify knowledge areas that you can expand and enrichen, detect problems in your clinical practice that might be useful to address (e.g. Why isn’t there a standardized protocol for (blank) here?), and develop potential ideas for research.

[4] A map of the mind

Last but not least, the notebook can serve as a measure and organizational tool for the knowledge one has already acquired. Keeping one’s thoughts and memories organized is a very important precursor to developing an easily and quickly accessible knowledge bank. The primary objective is to make your brain an efficient and effective database of knowledge and to use that knowledge to guide actions (e.g. the practice of medicine) in a meaningful way. The notebook should not serve as a replacement for the mind’s memory stores, but rather, it should serve as a visual aid (to trigger memories of learning from direct visualization and also to help guide a mind-only “memory palace”-style search if the notebook is absent) and as a hierarchical “site map” or “table of contents” that helps you keep track of what you know so far and what you don’t know.

I hope I have at least begun to convince you that the notebook and the active engaging and recording of lessons learned are essential for physicians at all levels of training. In my next installment of this series (The Battle for Your Mind), I will discuss different methods modern physcians can use to keep notebooks.

Today marks the end of the 2012 American Academy of Neurology annual meeting. I spent this past week (also my final week of vacation as a junior neurology resident) attending courses and lectures, perusing posters, meeting other neurologists, and trying to absorb as much neurology as possible in this short amount of time. AAN hosts the largest conference for neurologists around the world and is typically attended by 10,000 to 20,000. While some of the more advanced and groundbreaking science may gravitate toward the specific subspecialty society conferences (e.g. stroke, epilepsy, etc.), this conference is a fantastic opportunity for neurology residents to broaden their perspectives on the field.

These are the highlights from my week at the AAN annual meeting:

Monday:
[1] Acute Central Nervous System Infections – Infectious Diseases – This course organized by Larry David of the U. of New Mexico provided a brief overview of acute meningitis and encephalitis, the approach to diagnosis and treatment of these diseases, and the practical wisdom and experience used to help one differentiate between various syndromes. In particular, I found value in the emphasis on poor sensitivity of the classic signs of meningitis in elderly patients, the relatively high incidence of undetected nosocomial and multi-drug resistant meningitis in ICU patients with fever and altered mentation, the use of fluid resuscitation in preventing cerebral ischemia in meningitis, and an outlining of an approach to selecting diagnostic tests in encephalitis.

[2] Stroke in Children and Neonates – Vascular Neurology – This course organized by Lori Jordan of Vanderbilt University spanned the current body of knowledge on pediatric stroke as well as provided insight on the interventional trials being pursued, including the use of intravenous thrombolysis in acute stroke in children. While this course was primarily for the benefit of my wife (who is training as a pediatric neurologist), it was interesting to see what lessons the pediatric neurologists drew from the experience of adult stroke neurologists. In particular, the notion that stroke units (one of two interventions in acute stroke that has evidence for outcome benefit, the other being intravenous thrombolysis) were developed as a result of the use of IV tPA (a medication with limited effectiveness and very limited use throughout the country) is an interesting perspective.

[3] Catching up with Tulane’s Neurology department – It was nice having a few hours to catch up with Sheryl Martin-Schild (the director of the Stroke Program at Tulane University Medical Center) and some of the residents and attendings of the Neurology department, the program within which my interest in neurology initially developed. When I was a student, the department was in a state of recovery but appears to be growing quite nicely now. Perhaps not entirely surprisingly (given the high number of acute stroke and hemorrhage cases), several of the residents are pursuing further training in critical care.

Tuesday:
[1] Presidential Plenary Session – Stroke Prevention – While there were several interesting talks at this session, the one of greatest relevance and interest to me was a relatively straightforward statement by Ralph Sacco who recently stepped down as the President of the American Heart/Stroke Association, the first neurologist to hold that position. He spoke at length about both medical and lifestyle risk factors for stroke. He made the logical statement that racial/ethnic disparities in long-term stroke outcomes can be eliminated by addressing these risk factors, and he showed the evidence to prove this.

Wednesday:
[1] Neurotoxicology – General Neurology, Neuromuscular – This was a very interesting talk organized by Herbert Schaumberg of the Albert Einstein College of Medicine that introduced me to several clinical entities I was not well aware of before including cobalt neurotoxicity from metal-on-metal hip prostheses, drug-induced myoclonus in end stage renal disease (including with gabapentin, morphine, and even propofol), bismuth myoclonic encephalopathy, and fibrous myopathy from intramuscular injections. I also finally learned how to differentiate between ciguatera and scromboid toxins.

[2] Contemporary Issues Plenary Session – Immunology, Vascular Neurology – 500 cases of NMDA encephalitis, Imaging in Acute Stroke – Any talk claiming data on the outcomes for over 500 patients with NMDA encephalitis can easily capture the interest of a room full of neurologists, which this one did – a very, very large room. The other talk that caught my interest was a brief discussion by Maarten Lansberg of Stanford University of the current imaging modalities used in acute stroke. While this talk did not provide much new data, it was refreshing to have a focused review of the current recommended approach to using noncontrast CT scans, perfusion imaging, vessel imaging, and MRI in the acute setting.

[3] Neuro-Ophthalmology and Vestibular Lab – The examination of the eyes is one of the hardest parts of the neurologic examination, and I recognize this as one of the areas where I need a great deal more practice and refinement. Fortunately, this session was there to serve this need. While the lab/workshop sessions are relatively expensive, this provided me with very useful practical knowledge and skills, more so than any other session during this conference. The workshop had about a dozen stations where those taking the course could work directly with experienced neuro-ophthalmologists to refine examination skills, develop methodical approaches, and pick up a few new maneuvers. For me, I was able to refine confrontational visual field testing, the head impulse maneuver, the Dix-Hallpike and Epley maneuvers, and pupillary reaction testing, and I furthermore learned a few new methods of demonstrating psychogenic vision loss.

Thursday:
[1] Neurologic Complications of Medical Disease – General Neurology, Neuromuscular, Vascular Neurology – This course organized by Neeraj Kumar of the Mayo Clinic was a very neat and extensive session covering a variety of medical conditions. I took this course knowing that next year as a senior neurology resident I will be running the consult services and will have greater involvement in directing the care of patients without primary neurologic disease but with severe neurologic deficits and symptoms related to the dysfunction of other organ systems. The course provided overviews of rheumatologic diseases causing peripheral nervous system dysfunction, neurosarcoidosis, nutrient deficiencies, gastrointestinal diseases with neurologic symptoms, systemic malignancies and cancer treatments causing neurologic dysfunction, and finally systemic diseases causing ischemic stroke and intracerebral hemorrhage.

Friday:
[1] Practical Issues with Botulinum Toxin Use in Neurology – Movement Disorders – I have had no direct experience thus far as a resident with the use of botulinum toxin in neurologic conditions, so I took this course with the hope of having an introduction to its use. Furthermore, as a junior resident with predominantly inpatient ward duties, I have minimal exposure to neurologic movement disorders (which is an outpatient subspecialty within neurology). One major caveat for this course was that the various speakers all had several financial conflicts of interest related to the pharmaceutical companies that manufacture formulations of botulinum toxin; many off-label uses of the medications were discussed. Nonetheless, I particularly found value in the introduction to various dystonias and an overview of the different presentations of spasticity after stroke. Listening to one of the principal investigators for the trials related to botulinum toxin as a therapy for chronic migraine was also very interesting, particularly in his discussion of the pathophysiology and the distinctions he made between chronic migraine and other types of chronic headache (chronic tension-type headache, rebound analgesia).

I presented at AAN two years ago as a medical student. I only had enough time and money to present my work and did not get to explore much to the conference’s many educational resources. This time, my goals were focused entirely on education and broadening my own perspectives, with regards to differential diagnosis (learning about less common clinical entities), approaches to diagnosis and treatment, and the development of a career pathway. For numerous reasons, I wish that all residency programs would send their residents to AAN every year as it is a fantastic opportunity for growth and learning.

Over the past few weeks, I have reflected in great detail about the way I live my life: as a man, husband, friend, trainee, physician. Challenges inevitably stimulate growth, even if the new growth requires the burning away of old habits and beliefs. The past year and a half of my new career as a physician has provided numerous challenges, and accordingly I must find ways to change and grow. With the turning of the year, there are three areas of improvement that call upon my resolve.

Energy

As a senior at Harvard College, I took a course taught by Psychology professor Tal Ben-Shahar on the Psychology of Leadership during which a key theme was the cultivation of energy. A number of researchers in the business realm studied the habits and behaviors of high-stress/performance professionals (Olympic athletes, FBI hostage rescue operatives, trauma surgeons, etc.), and they found a unifying principle: that time is a limited resource, but energy can expand and grow. Performance failures are often attributed to the lack of time, but a significant part of the effectiveness of performance during a finite time period is related to the energy levels of the performer. This intuitively makes sense: at the end of a long work shift, every task, no matter how simple, takes longer and is more prone to error. Accordingly, improvement in performance should focus more on maintaining, growing, and effectively using one’s stores of energy and less on “time management.”

However, cultivating energy in the setting of medical residency training is very difficult. Over the past year and a half, part of my psychological programming has centered on self-preservation through protection of apparently limited energy stores. Time for sleep became more precious than ever. Forgoing social engagements for quiet nights at home became the rule. A constant reminder of the burden of fatigue played out in the form of a memory of a previous teacher’s only slightly hyperbolic experience: “After residency, I slept for three months.” A premedical advisor, a resident at the time, told me, “When you train in medicine, you can only bring one other thing with you, such as a hobby. For me, it was my marriage.” After each thirty hour or more on-call shift, my first priority was to sleep and allow my brain to heal, expecting that any deviation from this would result in worsening performance during subsequent work days and overnight shifts with accompanying demoralization.

Now, I am reevaluating this world view. I know there are physiologic bases for energy and fatigue. If nothing else, I have certainly performed enough Neurology consults for “weakness” that end up being medical evaluations for severe fatigue. There are limits to what the human body can routinely do. However, is routine the operative word? Can you change the human body’s routine to gradually require more and more energy mobilization and expenditure? Perhaps fatigue and chronic “sleep debt” are less a function of a depleted pool of energy, but rather, they represent a diminution of the means to quickly access energy stores. Am I still suffering from fatigue accummulated during my intern year, or am I “out of shape” with regards to acquiring energy? If so, what is the physiologic basis by which the body can be trained to more quickily mobilize stored energy? Can it be traced to an enzymatic process? At this time, I am managing to exercise on my elliptical machine almost every day, even if only for short bursts, yet even a fifteen minute session can keep me awake for hours in the evening working on projects and having meaningful conversations with my wife when otherwise I would sink deep into the couch and watch television.

Granted, there is a distinction between energy and willpower that I will not discuss in detail now. For the time being, my resolutions follow:

Abstract
[ ] Learn to cultivate energy
[ ] Train to mobilize energy stores

Concrete
- Exercise on the elliptical machine daily
[ ] for 7 days, [ ] for 14 days, [ ] for 1 month, [ ] for 3 months, [ ] for 6 months, [ ] for 1 year

Serenity

Many people find benefit in learning the art of meditation. It is not hard to see why this might be useful: we are constantly bombarded with information and sensory stimuli. For example, I can count seven electronic screens in the room where I am writing this entry, four of which are within my range of peripheral vision, three of which having shifting/rotating images. In addition, our interconnected world is filled with strong emotional stimuli: sensationalist news reports written to inspire a passionate response, Facebook photograph uploads of parties and weddings and gatherings that you wish you could attend, and status updates whether through social networks, e-mails, text messages, or more frequent (and incredibly inexpensive) cell phone calls. As with sleep, there is a strong desire to disconnect with the world and find a moment and place of peace.

As for me, I am terrible at meditation. Closing my eyes, counting, and other mind tricks are not enough to quiet my brain. When I wake up in the middle of the night, my mind immediately jumps to the tasks for the next day, including orders I need to place in the hospital, patients and colleagues I need to call or e-mail, and measures I need to take to make the day slightly more manageable. During intern year, I spent both my waking and asleep hours at the hospital: my dreams often involved walking the hospital corridors and running to Code Blues.

Nonetheless, I would like to find ways of calming the mind. One way I hope to do this is by rediscovering hobbies and pasttimes and exploring new ones. One disheartening development related to medical school and residency training was the loss of hobbies, including music and sports. And yet, a great deal of the benefit of these activities is the switching of focus from agitated and worrisome thoughts to a singular purpose, whether to create beautiful melodies, perfect a form or dance routine, or win a game.

One unexpected activity I have adopted is woodcarving, specifically whittling. For some time I have longed for an activity that uses the fine dexterity of my hands and also one that can produce something. One game I used to play as a younger man was to peel the skin of apples in a single uninterrupted spiral. I find much charm in this quote attributed to Michaelangelo: “Every block of stone has a statue inside it, and it is the task of the sculptor to discover it.” There is a beautiful simplicity in the art form: a block of wood, a knife, and a very small repertoire of cutting techniques that can be learned intuitively. So far, I have spent the past week gradually carving away at a small block of basswood to make the traditional first project which requires that one learns a few basic techniques: an egg. While I have only aspired to carve for ten minutes each day, I find myself cutting for longer periods of time as my mind quiets, relaxes, and finds some serenity.

Abstract:
[ ] Find serenity

Concrete:
[ ] Learn basic techniques of whittling/small woodcarving
[ ] Carve an egg
[ ] Carve a set of calipers
[ ] Carve a scholar’s rock
[ ] Carve a cheese knife
[ ] Carve a rabbit

Focus

For most of my life, I have followed the path of the jack-of-all-trades. I have often enjoyed the ability to learn new skills quickly, but mastery has not often been part of my trajectory. This has partly been due to having a wide variety of interests and a limited amount of resources (e.g. not having the money to have music lessons at an early age). Nonetheless, my career trajectory is moving me towards subspecialization, most likely in the field of Vascular Neurology, the field that is concerned with the treatment of stroke. Part of my passion for stroke comes from the fact that I have interest in many aspects of it: the disease pathophysiology (the many etiologies), the emerging and changing acute and neuroprotective treatment modalities, the need for better public health methods to get people to the hospital faster, the variety of care delivery strategies that different centers have established, and the great deal of research going into stroke rehabilitation and adaptation to post-stroke disability. Nonetheless, as my training progresses, it will help if I can explore this field with the aim to find a point of focus for my energy and intellectual desire. As such, my resolutions this year are:

Abstract:
[] To develop a point of focus

Concrete:
[ ] To find a concept of stroke that is not well understood and prepare to study it
[ ] To find an aspect of stroke care that can be improved upon and develop a means to achieve improvement
