The physical exam needs to change to make the most of technological advancements, says Abraar Karan<\/p>\n

\"abraar\"I received my first stethoscope from my mother, a psychiatrist who unsurprisingly had little use for the maroon instrument. I remember thinking that I wanted to be the doctor who knows how to use this better than anyone else. I went through clinical rotations paying close attention to the signs on a physical exam that could help secure a diagnosis for my patients. As a resident, I keep that same maroon stethoscope snug around my neck\u2014yet for most of the day, I find I have little use for it.<\/span><\/span><\/span><\/p>\n

I\u2019ve found that the physical exam is essential when I\u2019m evaluating a sick patient who is decompensating, but less so in routine day to day care. When I was an intern, one of my jobs in the morning was to see the patients before the rest of the team and to report my findings on rounds. For most patients, I began to notice that their exams were largely unchanged from previous days\u2014to the point where the clinical presentation quickly became a simple declaration of \u201cunchanged from yesterday,\u201d before I presented laboratory and imaging data.<\/span><\/p>\n

The physical exam alone can rarely obviate the need for more testing in cases where a patient has any other compelling findings from either their history or routine labs. For instance, a patient who I admit with fever and a cough will be better evaluated by a chest x ray than by my auscultation of their lungs with my stethoscope. In fact, even if my exam were to be completely normal, we would still send them to the x ray machine\u2014and if that was normal and the patient became more ill, we would probably upgrade to a CT scanner.<\/span><\/p>\n

Similarly, if my exam was abnormal\u2014say I heard crackles or minimal breath sounds\u2014I would still, in most scenarios, send the patient for additional imaging. This is to say that the physical exam, which in the past would be the central part of a doctor\u2019s visit with a patient, is now largely an additional data point that is usually, if not always, trumped by more objective, machine generated data, including vital signs (measured electronically), laboratory values (complete metabolic panels, complete blood counts etc), and diagnostic imaging (x rays, CT scans, ultrasounds, MRIs, PET scans, and more).<\/span><\/p>\n

Don\u2019t get me wrong\u2014there are still a number of situations in which I find the exam to be clinically essential, and it certainly has a solidifying effect on the doctor-patient relationship, but there needs to be a major shift in how we examine our patients to make the most of technological advancements. One of the key problems with the physical exam is the wide range of variability between doctors. That is to say: two doctors may look at the same patients and have two different interpretations of the exam. Yet this happens with less frequency when using other diagnostics, including advanced imaging such as bedside ultrasounds.<\/span><\/p>\n

One example that should be particularly familiar to most doctors is estimating a patient\u2019s jugular venous pressure (JVP) by visual inspection\u2014a common poor man\u2019s diagnostic in heart failure management. Studies have shown that <\/span>physician estimates of JVP vary widely<\/span><\/a> by the examiner, making the clinical finding hard to truly rely on. And we have increasing data to suggest that for some measures, bedside diagnostic equipment is superior: in a <\/span>study of internal medicine residents<\/span><\/a>, those who used handheld ultrasounds to assess right atrial pressure did so correctly 90% of the time, versus only 63% of the time in those who did so by physical exam of the JVP. As bedside ultrasounds become cheaper, we will see far more in clinical practice\u2014and we must ensure that clinical training seizes this opportunity as well. Currently, the\u00a0medical school curriculum on ultrasound is sorely lacking.<\/span><\/p>\n

While I predict that the physical exam in the inpatient setting will be most subject to technological transformation, even the outpatient annual physical exam demands a culture shift. The annual physical exam costs the healthcare system an estimated <\/span>$10 billion, and accounts for nearly 10% of visits to primary care doctors<\/span><\/a>\u2014arguably taking away time from more urgent and necessary visits. Moreover, there is no data to suggest that the annual physical has any direct clinical benefit. In theory, it keeps patients more connected with the health system, which is certainly valuable, but one might question if it\u2019s worth the cost mentioned\u2014and if there are better, more targeted ways to do this specifically for high risk patients.<\/span><\/p>\n

I am increasingly realising that even if I want to spend more time at the patient\u2019s bedside and less time in front of a computer (which trust me, I do), this may not actually be what is clinically best for the patient. Today more than ever before, doctors are bombarded with hundreds of data points that require quick analysis and decisive decision making. We also have far more therapeutic options now than we ever did before. While it\u2019s difficult for me to admit, I may be doing more for my patients by clicking a mouse through a table of numbers, and typing in text orders that will be executed by excellent nurses. With this in mind, I believe it is critical that we train more doctors in the regular use of affordable bedside diagnostics (including but not limited to ultrasound) to create a new standard for the physical exam. <\/span><\/p>\n

As a doctor, orchestrating the rest of the team to obtain the information I need to treat my patients has become an important, if not underrated, skill. I anticipate that some doctors of the old guard will read this with hesitancy, or even outrage, but medicine must change with the times to ensure that patient care is the best it can be.\u00a0Ultimately, putting a stethoscope on my patient may be more of a reassurance for them than it is for me, which makes it still worth doing. But going forward, we need to find a new modern standard for the physical exam t<\/span>hat physicians will find clinically optimal.<\/span><\/p>\n
