Correlación y concordancia entre el examen nacional de medicina y el promedio ponderado universitario: análisis de la experiencia peruana en el periodo 2007 – 2009.

Abstract

Objectives: To evaluate the correlation and concordance between the ‘Peruvian National Exam of Medicine’ (ENAM) and the Mean Grade Point Average (GPA) in recently graduated medical students in the period 2007 to 2009. Materials and Methods: We carried out a secondary data analysis, using the records of the physicians applying to the Rural and Urban Marginal Service in Health of Peru (SERUMS) processes for the years 2008 to 2010. We extracted from these registers, the grades obtained in the ENAM and GPA. We performed a descriptive analysis using medians and 1st and 3rd quartiles (q1/q3); we calculated the correlation between both scores using the Spearman correlation coefficient, additionally, we conducted a lineal regression analysis, and the concordance was measured using the Bland and Altman coefficient. Results: A total of 6 117 physicians were included, the overall median for the GPA was 13.4 (12.7/14.2) and for the ENAM was 11.6 (10.2/13.0).Of the total assessed, 36.8% failed the TEST. We observed an increase in annual median of ENAM scores, with the consequent decrease in the difference between both grades. The correlation between ENAM and PPU is direct and moderate (0.582), independent from the year, type of university management (Public or Private) and location. However, the concordance between both ratings is regular, with a global coefficient of 0.272 (CI 95%: 0.260 to 0.284). Conclusions: Independently of the year, location or type of university management, there is a moderate correlation between the ENAM and the PPU; however, there is only a regular concordance between both grades.
