Summary
Emergency medicine sub-internship timing does not affect student performance. Early summer rotations show no advantage over fall rotations for medical students applying to residency programs.
Area of Science:
- Medical Education
- Emergency Medicine
- Residency Training
Background:
- Emergency medicine (EM) sub-internships are traditionally held in summer to aid residency applications.
- The impact of sub-internship timing on student outcomes remains unclear.
Purpose of the Study:
- To investigate seasonal trends in emergency medicine sub-internship course outcomes.
- To determine if early summer rotations offer performance advantages over fall rotations.
Main Methods:
- Retrospective observational study of 84 EM-bound medical students (2021-2024).
- Compared outcomes (evaluations, SAEM scores, final grades) between May-July and August-October rotations.
- Utilized independent t-tests, Mann-Whitney U tests, and regression analysis.
Main Results:
- No significant differences in average evaluation scores (p=0.11), SAEM scores (p=0.32), or final course scores (p=0.21) between early summer and fall rotation groups.
- Performance metrics were comparable regardless of rotation timing.
Conclusions:
- Early summer (May-July) EM sub-internships do not yield better performance outcomes compared to fall (August-October) rotations.
- Rotation timing does not appear to be a significant factor in student success during EM sub-internships.
- Further research at multiple sites is needed to explore other factors influencing seasonal variations.
