Association between physicians' maldistribution and core clinical competency of resident physicians: a nationwide cross-sectional study.

objectivesWith physician maldistribution recognised as a global issue, Japan implemented the physician uneven distribution (PUD) index as a strategic measure. Currently, there is a lack of objective assessment of core clinical competencies in regions influenced by varying levels of physician distribution. In this study, we objectively assess the core clinical competencies in regions affected by physician maldistribution and explore the relationship between the PUD index and the clinical competencies of resident physicians. DESIGN, SETTING AND

participantsIn this cross-sectional study, we gathered data from the January 2023 General Medicine In-Training Examination (GM-ITE) survey. Participants included postgraduate year 1 and 2 resident physicians in Japanese hospitals mandating the GM-ITE or those who voluntarily took it. The GM-ITE scores of the resident physicians were assessed. The PUD index, a Japanese policy indicator, reflects regional physician disparities. A low PUD index signals a medical supply shortage compared with local demand. The trial registration number is 23-7.

resultsThe high and low PUD index groups included 2143 and 1580 participants, respectively. After adjusting for relevant confounders, multivariate linear regression analyses revealed that the low PUD index group had significantly higher GM-ITE scores than the high PUD index group (adjusted coefficient: 1.14; 95% CI 0.62 to 1.65; p<0.001).

conclusionsThe study revealed no clinically differences in GM-ITE scores between residents in regions with disparate physician distributions, suggesting that factors beyond PUD may influence clinical competency. This finding prompts a re-evaluation of whether current assessment methodologies or educational frameworks fully support learning across varied community settings.
