Patient understanding of medical jargon: A survey study of U.S. medical students

ObjectiveWith increasing exposure, medical students may forget that technical jargon is unfamiliar to laypeople. To investigate this possibility, authors assessed student perceptions of patient understanding across different years in medical school.Methods533 students at 4 U.S. medical schools rated the proportion of patients likely to understand each of twenty-one different jargon terms. Students were either in the first month of their first year, the middle of their first year, or the middle of their fourth year of medical school.ResultsFourth-year students were slightly more pessimistic about patients' understanding compared to new first-year students (mean percent understanding of 55.1% vs. 58.6%, p = 0.004). Students both over- and under-estimated patient understanding of specific words compared to published estimates. In a multivariate model, other factors did not explain these differences.ConclusionStudents do not generally presume that patients understand medical jargon. In many cases they actually underestimate patients' understanding, and these estimates may become more pessimistic longitudinally. Jargon use in communication with patients does not appear to stem from unrealistic presumptions about patients' understanding or from desensitization to jargon during medical school.Practice implicationsTraining about patient knowledge of medical jargon may be a useful addition to communication skills curricula.
