Medical house staff performance in physical examination

Area of Science:

• Medical Education
• Clinical Skills Assessment
• Internal Medicine

Background:

• Physical examination is a cornerstone of clinical diagnosis.
• Accurate physical examination skills are crucial for effective patient care.
• Errors in physical examination can lead to diagnostic inaccuracies and suboptimal treatment.

Purpose of the Study:

• To evaluate the types and frequency of errors in physical examinations performed by medical house officers (interns and residents).
• To identify specific areas of the physical examination where errors are most common.
• To explore factors influencing the accuracy of physical examinations.

Main Methods:

• A study involving 120 patients admitted to a medical service, presented at teaching conferences.
• Systematic examination of patients by house officers (interns and residents).
• Comparison of house officer findings with investigator assessments and analysis of error rates across different examination areas.

Main Results:

• Overall mean error rates were 5.8% for residents and 6.4% for interns.
• Cardiac examinations had significantly higher error rates compared to respiratory, abdominal, or thyroid examinations.
• Patients with abnormal cardiac or neurologic findings exhibited higher error rates in those specific areas.
• Inter-investigator agreement was higher than agreement between investigators and house officers.

Conclusions:

• Medical house officers commit errors in physical examinations, with cardiac assessments being a notable area of deficiency.
• Performance in physical examinations is influenced by the complexity of findings and potentially by the time spent by attending physicians.
• These findings underscore the need for targeted educational interventions to improve house officers' physical examination skills.
