“What do you think, Doctor?”
For a novice physician, these worlds can quickly jolt a relatively straightforward conversation into a jumble of partially formed thoughts, suppositions, jargon, and (sometimes) incoherent ramblings. Even for simpler questions, the fumbling trainee does not have a convenient script that has been refined through years of recitation. Thus, many conversations that residents have with patients are truly occurring for the first time. And unfortunately, this novelty can result in poorly chosen words that can have lasting effects. An inauspicious slip of the tongue could significantly alter the patient’s perceptions and decisions.
A recent study in JAMA Internal Medicine highlighted the connection between the words we choose and the actions our patients take. As Dr. Andrew Kaunitz reported in a summary of this article for NEJM Journal Watch, avoiding the word “cancer” in describing hypothetical cases of DCIS resulted in women choosing less aggressive measures and avoiding procedures like surgical resection. Dr. Kaunitz notes that the National Cancer Institute has also recommended against labeling DCIS as “cancer.”
I believe this recent study raises a major question at every level of medical education, particularly during residency. How do we counsel our physicians to counsel patients and communicate effectively? How do we choose words that appropriately convey the urgency of a diagnosis without scaring our patients into unnecessarily risky treatments?
I was fortunate to have gone to a medical school where our course directors were forward-thinking. Our preclinical curriculum included mentored sessions with practicing physicians and patient-actors. We were taught how to use motivational interviewing to facilitate smoking cessation, how to ask about a patient’s sexual orientation and gender identification, and even how to use the SPIKES mnemonic for breaking bad news.
Yet all of these simulations can never really prepare a trainee for the first time he or she is on the spot in the role of a real physician with a real patient. Counseling patients requires subtleties; no medical school curriculum could possibly address every situation. But as the above-referenced study by Omer at al. confirms, subtleties and shades of meaning matter.
Of course, not every situation that requires measured words will be so dramatic. The words we choose for more benign situations matter, too. How do I define a patient’s systolic blood pressure that always runs in the 130-139 mm Hg range? Do I tell him that he has “prehypertension,” or do I give him a pass in saying, “Your blood pressure runs a little higher than normal”? Would this patient exercise more if I choose “prehypertension”?
What do I say to my patient with a positive HPV on reflex testing of an abnormal Pap smear? “Your Pap smear shows an abnormality” or “an infection with a very common virus…” or “suspicious cells” or “an infection that might lead to cancer someday…” What effect will it have on how she approaches future abnormal results? How might she change her sexual habits? How might she view her partner or partners?
These days, med schools and residency programs are being increasingly taxed by the competing priorities in educating the 21st-century physician. As technology rapidly threatens to usurp our expertise in many domains of practice, communication will remain a cornerstone of our job. Communicating with patients will never be passe; no patient wants to be counseled by a computer. We must master these vital communication skills.
Unfortunately, studies like Omer et al. only touch the tip of the iceberg. How do we empower patients with information while not scaring them? When should we scare them with harsher language? How and where do we learn to choose the right words? And who decides?
Even a perfectly designed training system could not tackle all these questions. But perhaps we ought to be exposing our trainees to simulated conversations in which subtle word choices matter. Let’s face it: We could all do better at choosing our words wisely.

Discussions of resident duty hour reforms reached the point of ad nauseam a few years ago. Everyone had their say – Program Directors (“In 2003 we instituted an 80-hour work week, in 2011 we switched to 16 hour shifts, what’s next – online residencies!?”), senior residents (“What? I have to write H&Ps again? I don’t even know my computer password!”), interns (“I thought I was done with cross-covering after this year”), graduating medical students (“I get to sleep in MY bed most of next year!”), and various supervising bodies (“This is what the public wants. Of course there is evidence that these reforms will work.”). Now it’s my turn: part of the last class to have experienced 30-hour call cycles as interns – the way it should/shouldn’t be (depending on your bias).
While lamenting to my Program Director during residency on how my class not only had a difficult intern year but also had to assume “intern responsibilities” during my junior and senior years, he gently reminded me of his experience as an intern. It was routine for him to care for more than 20 patients on the general medicine service. Moreover, the ICU was “open” and any of his patients transferred to the unit continued to be under his care. Generously assuming 1 day off in 7, he worked more 100-hour work weeks than he’d care to remember.
As a junior resident, I was on service with my Chair of Medicine and he repeated many of the same stories of busy services and how the word housestaff came to be – the residents’ de facto house was the hospital. Was this dangerous? The unfortunate case of Libby Zion (and others) would suggest yes. Did my attendings became outstanding physicians, in part because of the rigorous training? Unequivocally.
Fast forward a few decades: for numerous reasons, including public pressure, an 80-hour work weeks with a maximum of 30 consecutive hours in-house (for a resident) and 16 consecutive hours (for an intern) is the new standard. In a matter of 16 hours, only so much can be accomplished. The work-up, diagnosis, and response to treatment is hardly appreciated in this short time span. The resident, who is permitted to stay in-house for 30 hours, often completes what the intern didn’t have time to do and benefits from observing in real-time the clinical course of the patient. Is this a disservice to the intern? Many would argue “yes.”
Interns now leave work after a maximum of 16 hours. The time away from the hospital is supposed to allow for a better-work life balance, enable restorative sleep, and prevent medical mistakes. A study by Kranzler and colleagues showed that this wasn’t the case. Interns did not report an increase in well-being, a decrease in depressive symptoms, more sleep, or fewer mistakes than previously.
What about patient care/outcomes? While early data from the 16-hour work day is still forthcoming, we do have recent data from the 2003 rule that capped the work week at a maximum of 80 hours. In a study published in August 2013, Volpp and colleagues examined mortality pre- and post-80-hour work weeks. More than 13 million Medicare patients (admitted to short-term, acute-care hospitals) who had primary medical diagnoses of acute MI, CHF, or GI bleed, or surgical diagnosis in general, orthopaedic, or vascular surgery were included in the study. The authors concluded that no mortality benefit was present in the early years after the 80-hour work week was implemented and a just a trend toward improved mortality was observed in years 4-5. We will start to see mortality data from the 16-hour rule in a few years, but I suspect that no significant improvements will occur in patient outcomes. In fact, medical knowledge and hands-on experience for interns might suffer.
Completing internship used to be a rite of passage, akin to pledging a fraternity. The duty hour changes have allowed for interns to spend more time away from the hospital so that, theoretically, they are less tired and make fewer mistakes at work. In practice, this might not be the case. Unquestionably, the brutal hours that generations of past trainees faced was suboptimal. but it appears as if the current duty hour rules also might be less than ideal from a learning perspective. Hopefully, in the coming years, the ACGME will reevaluate its policies in light of the data they will see.

This past week in NEJM Journal Watch General Medicine, Abigail Zuger reviewed an article from the Journal of General Internal Medicine by Lauren Block et al. in which researchers examined how medical interns spend their time. The results from this time motion study might be concerning but are not unexpected. The investigators found that interns on inpatient rotations spend only 12% of their time in direct patient care and spend only 8 minutes daily with each patient on their inpatient services. Dr. Zuger notes this “distressing paucity” of direct patient care should cause leaders in graduate medical training to effect change in interns’ daily routines.
To those of us in training or just out of training, the reasons for less direct patient care are myriad and obvious:
- A focus on multidisciplinary care and ever-increasing specialization results in each medical patient having a dozen or more physicians, consultants, nurses, pharmacists, case managers, social workers, and therapists directly involved in care. At this core of this legion of providers stands the intern. This novice physician must field messages, pages, and advice from all arms of the treatment team. As such, the intern spends as much time coordinating care as he or she spends relaying messages and answering “quick questions” — which are never quick and rarely are questions.
- Patient acuity in academic centers also continues to rise. Patients on medical wards often are admitted with multiple comorbidities and in a state of disarray. Rare are the relatively straightforward admissions for uncomplicated pneumonia or CHF exacerbation. Thus, interns have to manage a number of active conditions, complex medication lists, and a barrage of patient data.
- In addition, the Centers for Medicare and Medicaid pay us by DRGs and have also inculcated us to prevent 30-day readmissions. CMS will soon ask us to admit more patients to observation status. How do all of these shifts in payment affect a house officer? The intern has to spend all the more time ensuring safe and timely discharges. Tasks like medication reconciliations and communicating with outpatient providers suck up even more of the intern’s day at the expense of face time with the patient.
- Finally, documentation steals many a precious minute from the day. The considerations of patient acuity and reimbursement add to the burden of documentation leading to bloated notes that take far too much time to construct.
I am probably too young to be so cynical, but I do not see a shift in these routines occurring any time soon. And without be excessively cantankerous, I feel obligated to ask, “Does the percentage of interns’ time spent in direct patient care matter?”
An smaller percentage of interns’ time spent directly interfacing with patients may not mean that patients get worse care. We don’t have any direct data that the distressing paucity of direct patient care is resulting in poor outcomes. Moreover, the very “non-patient” tasks outlined above are entirely necessary in today’s inpatient environment. For example, if a patient is started on a LMWH bridge to warfarin in the hospital, figuring out how the LMWH will be paid for and who will follow the INR post-hospitalization is as important as time spent at the patient’s bedside.
Of course, I am not suggesting that intern work is inherently rewarding or educational. Most of us embark on this career path because we value interaction with actual human beings, not because we like electronic note templates. I myself romance about the days when internists actually took the time to perform thorough histories and physicals. But if we don’t encumber the interns with all of this work, who will do it?

When I started residency 4 years ago, warfarin was really the only choice of anticoagulation widely used for prevention of stroke in patients with atrial fibrillation (AF) and in patients with venous thromboembolism (VTE). Despite knowing about the coagulation cascade for decades, only recently have viable alternatives to warfarin become available. In this post, I hope to break down (at a macroscopic level) use of oral direct thrombin inhibitors (DTI). In my next post, I will review Factor Xa inhibitors.
To start, let’s review the basics of clotting (Figure below). Fibrin clots form after activation of the intrinsic and extrinsic pathways. Tissue injury initiates the intrinsic pathway and compromises the vast majority of the coagulation cascade. Warfarin inhibits vitamin-K dependent cofactors (II, VII, IV, X) in addition to protein C and protein S. Warfarin acts across both the extrinsic and intrinsic pathways to prevent thrombus formation. Direct thrombin inhibitors and Factor Xa inhibitors both work in the common pathway of coagulation.
Most DTIs are administered parenterally and used in patients with ACS and in treatment of patients with heparin-induced thrombocytopenia. Oral DTIs have been slower to reach the market. While several are under development, dabigatran received FDA approval in 2010 for prevention of stroke in patients with nonvalvular AF. The RE-LY trial, published in 2009,showed that low-dose dabigatran (110 mg twice daily) was noninferior to warfarin for preventing stroke in patients with intermediate risk nonvalvular AF (mean CHADS2 score 2.1). High-dose dabigatran (150 mg twice daily) was superior to warfarin in this population. The risk for major bleeding (compared with warfarin) was lower in the low-dose dabigatran group and similar in the high-dose dabigatran group. In 2013, the RELY-ABLE study, which extended the follow-up period (median of 4+ years) for patients in the RELY trial, showed similar rates of stroke and death in both groups of dabigatran. In another recent analysis of the RE-LY population, in which cardiovascular endpoints were weighted, researchers concluded that both doses of dabigatran have comparable benefits in prevention of stroke when taking into account safety and efficacy.
The bottom line is that dabigatran is efficacious for stroke prevention in nonvalvular AF patients. Not having to monitor one’s diet or monitor INR are practical advantages that dabigatran offers over warfarin. The inability to readily reverse bleeding associated with dabigatran should be a point of discussion with patients when choosing the appropriate anti-coagulation strategy (especially in elders or patients with histories of bleeding), however a dabigatran antidote will likely be available in the future.
Turning towards venous thromboembolism, dabigatran has been investigated for treatment of acute VTE and also for prevention of recurrent VTE. In both scenarios, dabigatran has shown positive results. In the RE-COVER study, published in 2009, patients with acute VTE were bridged with either warfarin or dabigatran (150 mg twice daily). No significant difference was found in the rates of recurrent VTE or major bleeding. Further trials (RE-MEDY and RE-SONATE) evaluated dabigatran versus warfarin or placebo in patients who completed at least 3 months of treatment for acute VTE. The results showed dabigatran treated patients had similar rates of recurrent VTE (and lower rates of major bleeding) than those on warfarin. Interestingly, a higher incidence of ACS was seen in the dabigatran-treated group. Less surprisingly, when compared with placebo, dabigatran treated patients had a lower rate of recurrent VTE (and higher rates of bleeding). As of now, dabigatran has not been FDA approved for treatment or prophylaxis of acute venous thromboembolism but is being used off-label for these indications by some clinicians.
To date, dabigatran is the sole oral DTI available in the U.S. and, as such, controls the majority market share in this class of medications. I anticipate newer generations of DTIs in the coming years. Stay tuned for the next post that will address Factor Xa inhibitors and their role in the treatment of atrial fibrillation and venous thromboembolism.

As a resident, probably the most common piece of feedback one receives is, “Read more and expand your clinical knowledge base.” This critique is a standard and generic piece of feedback to encourage the younger generation to never quit in the endless pursuit of knowledge. As our erudite attendings know, medical knowledge always evolves and often reverses course. Thus, the trainee is reminded to establish the habit of keeping up on the literature early in his or her career.
Indeed there is merit to following the literature vigilantly. This past month, Vinay Prasad et al. published on “medical reversals” in the Mayo Clinic Proceedings journal. In their analysis, Prasad et al. reviewed a decade’s worth of original articles in the New England Journal of Medicine. The authors found that more than 100 original articles had overturned previous guidelines or accepted practices. Notable examples — some of which are now old news — included the following:
- The standard teaching of CPR with rescue breaths was reversed by well-designed trials showing that adequate compressions were the main objective in CPR.
- KDOQI guidelines in 2000 were updated to reflect a target hemoglobin between 11 and 13 g/dL in patients with CKD. These recommendations were subsequently refuted on the basis of randomized control trial of epoetin alfa that demonstrated no major benefits and increased risk.
- Rosiglitazone was introduced in 1999 as a treatment for type 2 diabetes mellitus based on its ability to lower hemoglobin A1c. However, a meta-analysis in the New England Journal of Medicine later concluded this drug was associated significantly with cardiovascular death.
The list goes on and can be found in the article’s supplementary materials. If you’re inspired by Prasad’s findings, you ought to make every effort to “read more” and “keep current.”
Then again, maybe better advice for trainees would be, “Read when you can, but don’t worry if you end up falling a few years behind in the literature.” Sure, a revolutionary medical practice might arise, but even residents are unlikely to be so tuned out to the world that they won’t hear about the latest breakthrough somewhere. New treatments will surface; new drugs will be manufactured. The trainee may want to see a novel therapy survive a few years of validation in real clinical practice before stepping out onto a limb of uncertainty. If one aggressively tracks every advance in medicine, one also runs the risk of adopting a practice that later proves more harmful than anticipated.
At least one recently published article speaks in favor of this more lax approach toward the literature. As Paul Mueller highlighted in a NEJM Journal Watch article this past week, many meta-analyses add very little to the growing body of medical literature except growth of the body itself. If you haven’t read a meta-analysis on the pharmacotherapeutic options for fibromyalgia or supplements to prevent colon cancer in the last handful of years, don’t worry: The article you read in 2009 had most of the same studies. A more rational approach might be to pull meta-analyses on an as-needed basis rather trying to stay ahead of the barrage of articles published weekly.
So what’s the best strategy for a trainee? I personally favor a “headlines, tweets, and abstracts” approach — not only for the time-strapped resident but for myself too. Skim a few journals each month, and subscribe to essential Twitter and RSS feeds. You might hit the right balance of staying current and staying above the fray.

“Four out of four!” exclaimed a proud PGY1 as she handed me the billing sheet for her last patient in continuity clinic.
“Four out of four?” asked I.
“Yes, I gave all of my patients their updated Tdap today,” she boasted.
As her preceptor, I commended her for her commitment to routine health maintenance — you know, the supposedly routine tasks that, instead, routinely get pushed to the bottom of the patient’s problem list. I remarked that I had only administered a total of four Tdap vaccines in my 3 years in resident clinic.
Of course, I was exaggerating, but I admit that immunizations often got lost in the shuffle of resident continuity clinic. After an exasperating primary care encounter, the last thing I wanted to hear from my preceptor was, “Has she had her tetanus shot?” And I could imagine few things more defeating than quibbling with a patient over whether flu vaccines cause the flu, pneumococcal vaccines actually reduce the risk for pneumonia, and so on.
With so many competing priorities, so many new patients, and so many old dictations to scan — maybe someone had already vaccinated Mrs. Jones and actually documented it! — I often felt that the burden of vaccinations was too much to bear. But should I be chided for my negligence?
This week Paul Mueller of NEJM Journal Watch reported that the pertussis vaccine is only moderately effective in adults. The data derive from a large case-control study of patients under the care of the Kaiser Permanente group in northern California. The vaccine was reported as “53% effective” against clinical pertussis infection.
I actually pulled the BMJ article, and a few things stuck out:
While the vaccine indeed reduced the odds of contracting pertussis, the majority of cases that did occur were not terribly severe. Only a total of 1.2% of patients with PCR-positive tests actually needed to be hospitalized; rates of hospitalization were not reported for PCR-negative controls.
Most patients in the study had been vaccinated in the past 2 years. If immunity wanes over time, then 53% effective may be about as good as we will see in clinical practice.
Effectiveness, the statistic of interest, is a measure of 1 minus the odds ratio. If one looks at the odds ratio, the statistics are a little less impressive.
I now feel a little more justified in my previous approach toward vaccines but am left torn over what to teach residents that I precept. If a patient has a short agenda and a clean bill of health, then the primary care provider has no excuses. However, if one spends 30 minutes counseling on smoking cessation, working toward better glycemic control, or advising colonoscopies, why worry about the Tdap?
Then again, perhaps the proud intern knew best. After all, this study confirms that pertussis vaccinations indeed are effective. If clinicians take perspective of our public health colleagues, then we ought to work to preserve herd immunity and protect the most vulnerable populations.

Welcome, everyone! I am thrilled at the prospect of sharing with you my thoughts on issues that pertain to residency training during the current academic year.
I recently attended the Fundamentals of Critical Care Ultrasound course hosted by the Society for Critical Care Medicine (SCCM). It was well attended by a mix of intensivits, anesthesiologists, and emergency medicine physicians all looking to further their practices with ultrasound skills that can be utilized on a daily basis. In two days, we gained a working ability to evaluate basic cardiac function, identify significant pericardial and pleural effusions, recognize ultrasound signs associated with a pneumothorax, perform a DVT screening exam, assess volume status, and obtain vascular access.
Informally, I polled a handful of the faculty on whether they teach their residents these skill sets. While the emergency medicine and anesthesiology faculty generally incorporated routine use of ultrasound in their teaching, few internal medicine faculty said that they do. Increasingly, internal medicine programs integrate technology in the form of iPads and smart phones into their curriculums, yet few programs teach ultrasound.
During the evenings/nights when attendings and fellows are typically away from the hospital, resident interpretations of chest radiographs, CT scans, and EKGs have are routine elements used to aid clinical decision-making. Similarly, ultrasound can and should be used in a variety of settings as an extension of the physical exam.
A needs assessment1 of medical students and internal medicine residents conducted in 2010 showed a clear desire to integrate ultrasound training into established curriculums. The natural question asked: is it feasible to teach internal medicine residents basic ultrasound skills that are readily applied to clinical care? Without hesitation, I would answer yes!
While a growing body of evidence in the emergency medicine and even medical school curriculum literature highlight successful implementation of an ultrasound curriculum, less has been published with respect to internal medicine residency programs. Several small studies have shown the effectiveness of ultrasound simulation modules2, resident-driven assessment of cardiovascular function using ultrasound3, and heightened procedural confidence with ultrasound4.
While our residents at the University of Chicago have been using ultrasound for years to aid in procedures, we have not utilized a consistent curriculum. The brainchild of a former Chief Resident, Dr. James Town, we are in the midst of creating a standardized ultrasound curriculum for the internal medicine residency program. The curriculum provides formalized instruction on easy-to-acquire skills: using ultrasound for central venous access, measurement of IVC and IJ diameters for volume assessment, and DVT screening. Planned elements for the next phase of education will include ultrasound use for thoracentesis/paracentesis, evaluation of cardiac function, and identification of a pneumothorax.
Starting this year, we conducted formal ultrasound training sessions for nearly all of our housestaff. Following a pre-test and introductory lecture, interns and residents practiced ultrasound skills in groups of three or four on live models with the aid of a faculty member.
We also plan to host weekly “office hours” whereby trained faculty members in pulmonary/critical care and cardiology will be available on the wards to review images/clips that residents save onto USB drives. In addition, we are developing an ultrasound library of collected images/clips that can be used for future teaching and training.
Ultimately our goal is to create a proficiency list of ultrasound skills each resident must accomplish by the time he or she graduates. While it might take years before the American Board of Internal Medicine mandates residents have competency in ultrasound use, there is no question that ultrasound will increasingly find its way into internal medicine graduate medical education. Better to start sooner rather than later!

As a medical student, I never really understood the fuss over it. Practicioners had an excellent and concise guide in the JNC-7 to handle all of the major aspects of this disease. The JNC-7 guidelines were algorithmic, and a helpful table of compelling indications for antihypertensive agents couldn’t make life any easier.
I soon realized a little more finesse was required of the internist-in-training. JNC-7 didn’t tell the whole story. My attendings all had slightly different opinions on the optimal strategies for control, and these approaches might contradict my antihypertensive gospel.
Hydrochlorothiazide was replaced by chlorthalidone after a preceptor noted, “All of the important studies on thiazides were done with chlorthalidone.” After adopting its use, I found another internist who advised, “Chlorthalidone just causes more hypokalemia. There’s no reason to believe HCTZ is inferior.” So, back to HCTZ. Soon after, I learned that calcium-channel blockers were a preferred option for isolated systolic hypertension in elders. “Diuretics just make older patients dizzy, dehydrated, and hyponatremic.” And the advice continued to accumulate in the form of these little pearls.
To complicate matters further, various societies and expert-written guidelines also had a slightly different take on the ideal systolic and diastolic pressures. I was becoming dizzy myself. Do I target a systolic blood pressure of 130 mm Hg in patients with diabetes? Or was that patients with CKD? Or is the diastolic blood pressure more important? And does it really matter?
Well, if JNC-8 looks anything like the Eurpoean Society of Hypertension/European Society of Cardiology joint guidelines that are so nicely summarized in Joanne Foody’s NEJM Journal Watch article, we can all breathe a sigh of relief. As Dr. Foody highlights, these guidelines emphasize a more universal blood pressure target of 140/90 mm Hg and a greater focus on global cardiovascular risk. I haven’t gotten through the whole document, but I was also glad that these guidelines allow for more lenient control in elders. And these guidelines are not at all prescriptive in the choice of antihypertensive medications.
A brief report in Physician’s First Watch on a common class of antihypertenisves also caught my eye this past week. Staff writer Amy Orciari Herman reported on the recent JAMA Internal Medicine article by Christopher Li et al showing an association between long-standing calcium channel blocker (CCB) use and risk for breast cancer.
The article gave me pause for one major reason: I really fell in love with CCB’s as a house officer. CCB’s struck me as an affordable, convenient, and efficacious antihypertensive class. Amlodipine in particular seemed to promise worry-free prescribing to this young physician. Patients liked the once-daily dosing and small pill size. Since amlodipine required no periodic electrolyte checks and side effects are uncommon, I would gladly discharge a patient from the hospital on it. If the patient was lost to follow-up, I probably wouldn’t be on the hook for an adverse drug effect.
Or maybe I will be. This population cohort study suggests an elevated risk of breast cancer with CCB’s. While this study doesn’t prove causality, it should make us all a little more circumspect about the antihypertensives we choose.
In the end, these articles gave me a chance to reflect on what we ought to teach residents about managing hypertension. I expect I will keep my teaching simple in the coming years:
- Go for 140/90 in everyone; be a little more lax in those with advanced age.
- Make sure your choice of an antihypertensive is rational.
- Every drug has side effects and risk; make sure your choice to treat hypertension is rational.

Friends and colleagues, welcome to the new academic year! I am delighted to be a chief resident blogger for NEJM Journal Watch for the coming year. Without further ado, let’s discuss residents’ use of antibiotics.
Antibiotic selection can either be one of the most anguishing or most mindless decisions that an internal medicine resident makes. For some patients, defaulting to a broad spectrum makes sense. A patient with neutropenic fever who is in shock deserves stat delivery and subsequent administration of almost every antibiotic in the pharmacy — at least until culture data can guide more informed decisions.
On the other hand, some patients require a little more deliberation in nuance. Most residents have probably dealt with some degree of self-torment in choosing antibiotics.
- Is this really a community-acquired infection? A true community dweller is hard to find these days, and didn’t I just read something about infections like MRSA and C. difficile making their way out into the community?
- Is this antibiotic regimen really the correct spectrum? I know my Sanford guide says so, but this patient just looks too sick to use a narrower spectrum. Maybe I’ll broaden just so I don’t miss something, and I’ll let my attending decide when to narrow.
- I know not all fevers are from infection, but how can I justify withholding antibiotics on rounds tomorrow? What if my patient ends up in the ICU because I didn’t start antibiotics?
- The pharmacy says the antibiotic I want to use is restricted for use by the Infectious Disease consultants only. But my patient needs this antibiotic… Besides, the most critical thing I can do for a septic patient is give them broad-spectrum antibiotics as quickly as humanly possible, right?
A recent NEJM Journal Watch article broaches these topics and offers a little solace to the conscientious and excessively deliberative house officer.
Abigail Zuger reviewed an article by Charani et al in Clinical Infectious Diseases that evaluated prescribing practices in four London hospitals. The authors interviewed nurses, pharmacists, and physicians and identified that a “prescribing etiquette” is woven into the culture of medicine. There were several aspects to this culture that we’ve all likely experienced:
- Colleagues do not want to question another’s autonomy. For example, a pharmacist might defer to a senior attending’s antibiotic selection even if the pharmacist perceives it as irrational.
- Everyone tolerates noncompliance with policies. Thus, even though a stewardship plan is in place, stewards might be lenient with policies and might not offer much of a hindrance to poor prescribing practices.
- Even though trainees write most of the orders for antibiotics, the approach to antibiotic therapy is gleaned from attendings and consultants. A hospital might have prescribing policies, but trainees are more likely to be influenced by the patterns of other prescribers instead.
This culture probably makes the resident more vulnerable as well. If the antimicrobial stewards are unable to regularly enforce their policies, then the resident has even less leverage. Given this culture and the uncertainty in our own knowledge and skills, who can blame a house officer for the “broad is best” and “more antibiotics are better than less” approaches?
I look forward to your comments.

August is here, and we are deep in the throes of a new academic year. With this annual cycle, we deal with transitions in the academic medical world – many of which seem somewhat painful at first glance but, on closer inspection, actually can be quite fun. Many of you in medical training undoubtedly have moved into new roles: be it matriculation from student to intern, or adjusting to the care manager and team leader simultaneous roles with the switch from intern to resident. The transition from junior resident to senior resident typically is less dramatic, but generally means more time for self-directed learning and a focus on the next steps in your career. Arguably, the most unnerving transition is that from senior resident to independent practitioner. That said, a great number of NEJM Journal Watch readers have likely opted to continue training and begin fellowship (the category to which I belong!).
A few researchers have looked into whether this abrupt transition each academic year has an effect on patient care. Dubbed the “July effect,” studies have shown some evidence of decreased quality of healthcare in July (with careful attention to how quality is defined). A meta-analysis of such studies was published in the Annals of Internal Medicine in 2011 (see the NEJM Journal Watch summary here), which reported higher patient mortality, as well as lower hospital efficiency during this trainee transition period. However, the evidence is not strong, and further inspection with high-quality studies is needed. I would argue that, in fact, new trainees have an intense focus and are highly motivated to do an excellent job – particularly when starting at a new position. Combining this with attending physicians who take a more hands-on approach to guiding their trainees so early in their careers, I believe a strong argument can be made that patients receive better, if not equal, care in July as in other months. Regardless, attentiveness to detail and a low threshold for seeking help when needed is prudent, particularly during these first few months.
The new academic year has also brought my own transition to fellowship training; it has been an incredibly exciting progression (and sometimes scary!) to now call myself a cardiology fellow. This transition has provided me with new motivation to understand and master new skills, this time not only to increase my knowledge base with specific focus on cardiovascular medicine, but also to prepare for eventual independent practice as a cardiologist. The transition from chief resident to first-year fellow has been quite humbling at times, but I clearly remember the transition from medical student to intern just a few years ago – it’s not significantly different!
As you might have guessed, this new role for me also means the time has come to pass the baton of the Journal Watch Chief Resident Blog to a new pair of authors, to whom you’ll be introduced shortly (stay tuned for a new post soon…). I wish each of you the best of luck in your new positions, whatever and wherever they may be!
