Musculoskeletal Conditions in the Emergency Room: A Teaching Opportunity for Medical Students and Residents.

Objective: Assess the potential value of an emergency room (ER) for the teaching of musculoskeletal (MSK) medicine to medical students and residents in training.

Methods: Data from all encounters to the ER of a teaching hospital for calendar years 2016-2019 were extracted from an electronic database. Encounters with ICD-10-CM M codes (MSK system) and S codes (injury) were selected (MSK encounters). Frequency distributions were calculated by year, sex, and age group for all encounters and MSK encounters. Annual distributions of encounters involving the shoulder, hip, knee, and ankle joints were assessed.

Results: The number of unique patients seen during the four-year period was 84,094, and the number of encounters was 187,829 (Median: 1 encounter; interquartile range: 1-2). The mean number of encounters per year was 46,957 (range: 45,311- 48,382). There was no seasonal variation. Most patients were women (45,868; 54.6%) and young (20 29 yr.) adults (15,012; 17.8%), and these groups generated the largest numbers of encounters (women: 108,799; 57.9%; young adults: 35,969; 19.1%). A total of 41,353 encounters (22.0% of all encounters) involved the MSK system. The shoulder, hip, knee, and ankle were involved in 2,768 (1.5%), 1,592 (0.8%), 3,082 (1.6%), and 1,718 (0.9%) encounters, respectively. The most common conditions for each joint were shoulder pain, femoral fracture, knee contusion, and ankle sprain.

Conclusion: Our findings suggest that ER physicians should have broad knowledge of MSK conditions and injuries. An ER is an excellent location for the teaching of MSK medicine to medical students and residents of other training programs.
