Medical resident's pursuing specialty and differences in clinical proficiency among medical residents in Japan: a nationwide cross-sectional study

Importance: Standardized examinations assess both learners and training programs within the medical training system in Japan. However, it is unknown if there is an association between clinical proficiency as assessed by the General Medicine In-Training Examination (GM-ITE) and pursuing specialty.

Objective: To determine the relative achievement of fundamental skills as assessed by the standardized GM-ITE based on pursuing career specialty among residents in the Japanese training system.

Design: Nationwide cross-sectional study.

Setting: Medical residents in Japan who attempted the GM-ITE in their first or second year were surveyed.

Participants: A total of 4,363 postgraduate years 1 and 2 residents who completed the GM-ITE were surveyed between January 18 and March 31, 2021.

Main measures: GM-ITE total scores and individual scores in each of four domains assessing clinical knowledge: 1) medical interview and professionalism, 2) symptomatology and clinical reasoning, 3) physical examination and treatment, and 4) detailed disease knowledge.

Results: When compared to the most pursued specialty, internal medicine, only those residents who chose general medicine achieved higher GM-ITE scores (coefficient 1.38, 95% CI 0.08 to 2.68, p = 0.038). Conversely, the nine specialties and "Other/Not decided" groups scored significantly lower. Higher scores were noted among residents entering general medicine, emergency medicine, and internal medicine and among those who trained in community hospitals with higher numbers of beds, were more advanced in their training, spent more time working and studying, and cared for a moderate but not an extreme number of patients at a time.

Conclusions: Levels of basic skill achievement differed depending on respective chosen future specialties among residents in Japan. Scores were higher among those pursuing careers in general medical fields and lower among those pursuing highly specialized careers. Residents in training programs devoid of specialty-specific competition may not possess the same motivations as those in competitive systems.
