In the consultation room: how can a patient’s behavior interfere with diagnosis?

What the experiment showed

Patient behavior that a doctor finds difficult may draw more attention than the information needed for diagnosis. In a randomized experiment, 74 resident physicians worked through written cases portraying different patient behaviors. How the patient was portrayed affected diagnostic accuracy in the simulated task. This is a reason to consciously return to diagnostic thinking after a tense exchange, but not evidence that every upset patient leads to an error. The study did not measure mistakes during actual visits, so the size of the effect cannot be applied to everyday practice. The practical conclusion is more modest: notice your emotional reaction, then base the clinical assessment on symptoms, examination and available test results.

The first attention trap

The first trap arises when the doctor chiefly remembers the confrontational tone of the conversation and has more trouble recalling the course of the patient’s symptoms. It is worth pausing to ask whether you are focused mainly on your irritation rather than organizing the clinical information. Briefly noting the key points from the history, objective findings and possible diagnoses may help before one hypothesis dominates the rest of the assessment. This is a suggested way to refocus attention, not a method shown in the cited experiment to prevent errors in clinical practice. If tension makes it hard to continue the conversation or gather necessary information, you can ask someone else for support. The aim is not to ignore the patient’s behavior, but to keep it from replacing an assessment of their health.

Returning to the diagnosis

After a difficult exchange, you can identify the most likely diagnosis alongside a serious alternative that would matter if missed. Then look for evidence that does not fit the first hypothesis: a symptom, an examination finding or a gap in the history. Questions such as “What do I already know?”, “Which important symptom have I not yet assessed?” and “What information am I missing?” can interrupt a spiral of judging the interaction. Even if the conversation was unpleasant, it should not bring further inquiry to a halt. If a decision depends on observation or further results, agree on when the patient will be reassessed. Returning to the evidence and the plan is a suggested approach, not a guarantee of an accurate diagnosis.

Documenting without labels

The word “difficult” can easily move from conversation into the medical record, even though it says little about what happened during the visit. If behavior interfered with taking a history or performing an examination, it is better to describe it specifically and state what information could not be obtained. The next clinician then receives an account of the situation rather than a ready-made judgment of the patient as a person. In a randomized experiment involving medical records, stigmatizing language affected the attitudes of clinicians who subsequently reviewed the case. An erratum was published for that paper. The finding should not, however, be treated as a measure of the frequency of real-world diagnostic errors. Precise documentation does not require leaving behavior out; it separates observations relevant to ongoing care from a label that could steer the next assessment.

When a patient is agitated

When a patient is agitated, the first step is to assess safety and consider whether medical causes could underlie the behavior. A brief conversation should have a clear aim: to obtain the information needed for a safe decision, even if there is no time to discuss everything immediately. In the face of a threat, you can set a clear boundary without treating it as a reason to forgo necessary diagnostic assessment. If the risk escalates, call for help and adapt the rest of the visit to the situation. Then ask again about symptoms and review the available evidence, rather than treating agitation as an explanation for every complaint. These are practical suggestions, not findings from an experiment demonstrating that a particular procedure works.

Consultation and course correction

When the evidence does not form a coherent picture, it is worth asking a colleague for an independent interpretation. Presenting a specific symptom, result and alternative hypothesis is more useful than saying the patient “is a problem.” The doctor can also be honest about what remains unknown and what information would help them decide. A review of how diagnostic uncertainty is communicated in primary care highlights its importance in the patient relationship; it does not justify postponing a necessary clinical decision. If new results emerge or the evidence conflicts with the initial hypothesis, the plan needs to be reviewed. Consultation helps correct the reasoning; it does not transfer responsibility for the assessment to someone else.

A lesson for training

In training, the same case could be presented with a patient behaving politely and impolitely, followed by a comparison of which symptoms and differential diagnoses participants considered. The discussion afterward should focus on the reasoning process, not on judging the doctor’s character or blaming the patient. This is a suggested use of scenarios to help identify the point at which behavior begins to obscure clinical information. The randomized experiment involving 74 residents showed that behavior portrayed in written cases affected the accuracy of answers in a simulation. It does not tell us how large the effect would be during everyday visits. Nor does it support a promise that a single checklist will eliminate the problem; the exercise should encourage clinicians to revisit their hypotheses.

A patient’s behavior can draw attention away from their symptoms. Research points to a risk in simulated tasks, while practical steps can help doctors organize their thinking after a difficult conversation.

Empatyzer in conversations with patients who frustrate doctors

After a tense exchange, a doctor may want to return to the history, but first needs to notice their own reaction. In “About Me,” they can reflect on what prompted their frustration. Em then helps them prepare two short sentences: one setting a boundary around behavior that is disrupting the visit, the other asking about a symptom. These phrases help separate what the patient did or said from the symptoms they report, without pretending the tension did not happen. Talking to Em about themselves can help the doctor choose clear words that maintain contact with the patient and redirect attention to the purpose of the visit. The doctor can also prepare a list of questions to return to once the conversation has calmed down. Micro-lessons can help them recall opening questions and return to the symptoms. None of these steps replaces a safety assessment, diagnostic workup or a decision to ask for help when the situation calls for it.
