USE OF STANDARDIZED PATIENTS TO IDENTIFY DEFICITS IN STUDENT PERFORMANCE AND CURRICULUM EFFECTIVENESS

Much literature supports the value of performance-based tests for obtaining an overall assessment of clinical skills; however, these tests can also identify specific deficits in medical curriculum and student learning. This study, conducted over a period of 2.5 years, used standardized patients to identify deficiencies in medical students' evaluation of a patient with ''hoarseness and cough.'' Each of 230 students performed a physical examination and took a medical history, and each was evaluated on 29 items according to predetermined criteria. We conclude the following: (1) When examining a patient complaining of hoarseness and cough, students frequently did not screen for hemoptysis, thyroid problems, and otalgia; (2) Overall test performance correlated positively with the time of year of the rotation, but screening for certain items (including hemoptysis, thyroid problems, and otalgia) appeared not to depend on rotation; (3) Several important items significantly differentiated the more knowledgeable student from the less knowledgeable student.
