Clinical Report: The Clinical One-Liner: How a Single Sentence Can Guide and Bias Clinical Reasoning

Overview

The article describes how a patient’s one-liner can shape diagnostic reasoning before a clinician has independently verified its contents. In the case presented, prior labels of systemic lupus erythematosus (SLE) and recurrent pericarditis framed the assessment of chest pain, while an example of “PE” misread as pulmonary embolism illustrates how an erroneous chart entry can persist through copy-forward documentation.

Background

A one-liner commonly summarizes a patient’s age, gender, and relevant history and can serve as an initial frame for clinical assessment. The article notes that records may contain incomplete problem lists or unverified wording carried forward from earlier notes, amid time constraints, documentation burdens, and billing requirements. Such information can influence diagnostic thinking, including through anchoring bias, and may affect decisions beyond the immediate encounter. At the same time, documentation and copy-forward practices support information retrieval, research, billing, and communication between hospitals.

Data Highlights

• The article presents a clinical case involving Ms. B, a 47-year-old woman whose chart listed SLE and recurrent pericarditis. Her chest pain was attributed to recurrent pericarditis and treated with steroids.

• The case discussion notes a mildly elevated troponin and an unchanged electrocardiogram, and questions whether the charted diagnoses and alternative explanations had been adequately assessed.

• A separate example describes “PE,” intended to mean “physical exam” in an old note, being misinterpreted as pulmonary embolism and copied into the chart for years.

• The article uses these examples to illustrate how unverified chart information can shape clinical reasoning and influence decisions, without reporting numerical study or trial results.

Key Findings

• The one-liner can influence clinicians’ diagnostic thinking before they have met or assessed the patient.

• In the case of Ms. B, a 47-year-old woman with charted SLE and recurrent pericarditis, chest pain resembling prior episodes was attributed to recurrent pericarditis and treated with steroids despite a mildly elevated troponin and an unchanged electrocardiogram.

• The article raises questions about whether the SLE diagnosis had been verified against serologies and diagnostic criteria, and whether alternative explanations, including a gastric ulcer related to prior steroid exposure, were considered.

• Once a chart label frames the assessment, clinicians may be at risk of anchoring: accepting information that supports the presumed diagnosis while discounting symptoms that do not fit.

• Dr. Wachter’s example describes “PE,” originally meaning “physical exam” in an old note, being interpreted as pulmonary embolism and copied into the chart for years before the error was recognized.

• The article states that chart information can also affect surgical candidacy, insurance eligibility, employment in some fields, and patient treatment when nonspecific pejorative labels are recorded.

Clinical Implications

The article calls for clinicians to verify diagnoses included in a one-liner and to use focused questions about relevant positive and negative symptoms after reviewing the chart. It frames this approach as “trust but verify,” while recognizing that documentation and copy-forward practices also serve important clinical and operational functions.

Conclusion

A one-liner can efficiently convey history but may also perpetuate unverified diagnoses and shape subsequent reasoning. The article emphasizes verification of charted diagnoses at both clinician and system levels.
