Abstract
Internal medicine faculty at the Mayo Clinic designed a clinical evaluation exercise that separates assessment of physical examination skills from that of medical interviewing and reasoning skills. This report summarizes the first year's experience with assessment of basic physical examination skills. A core faculty of five general internists and three internist subspecialists designed a 45-item general examination checklist (e.g., measure blood pressure, examine mouth, palpate liver, drape to ensure privacy). In addition, the core faculty generated a menu of 27 focused examination skills (e.g., examine for carpal tunnel syndrome) from which the faculty examiner would select five items for the resident to perform. Each checklist item was scored 0, 1, or 2 for a maximum possible score of 100. The core faculty selected a criterion-based scoring reference and established a passing score of 90 based on practice examinations with residents and faculty. The core faculty made an instructional videotape of a model examination that was available to all residents. In 1991-92, prior to examination, the checklist was distributed to all first-year categorical (43), preliminary (25), and newly appointed second-year residents (eight). Of the 76 residents examined, 11 (14%) failed and 65 (86%) passed. All failing scores were 86 or lower. The absence of scores 87, 88, and 89 suggested that faculty upgraded borderline performances. All 11 residents who initially failed retook the examination and passed. The five most commonly missed items were (1) inspect the skin, (2) complete examination in logical sequence, (3) palpate aorta, (4) auscultate anterior breath sounds, and (5) palpate axillary and inguinal nodes. Other important observed errors were failure to measure vital signs, confusion of liver and spleen, failure to use bell on stethoscope, and inadequate breast examination. Twenty-eight residents completed an optional feedback form. Reviews were mixed but generally favorable. Assessment of the basic physical examination skills of the internal medicine residents was useful, and such skills were able to be assessed separately from physical diagnosis skills and interviewing skills. Direct observation of basic physical examination skills revealed important deficiencies, which provided opportunity for remediation.
