摘要:Objective: The purpose of this study was to identify factors associated with UKDI score amongst medical students in Indonesia. This study also sought to determine which factor that has the strongest association with UKDI score. Method: This is an explanatory research method with retrospective approach, conducted based on past medical students’ record. Samples were medical student who commenced study on year 2006 / 2007 / 2008 when KBK was implemented and they must have had passed one-time UKDI. Data collection was done on medical schools who agreed to provide the record of their medical students. Association between variables was analyzed using Chi-square test and Multiple Logistic Regression analysis. Result: Factors significantly associated with UKDI score were pre-clinical year GPA score category 3.51 – 4.00 (OR = 3.46, CI = 2.06 – 5.81; P < 0.001) and category 3.01 - 3.50 (OR = 4.14, CI = 2.63 – 6.53; P < 0.001), clinical year GPA score category 3.76 - 4.00 (OR = 6.46, CI = 2.91 – 14.34; P < 0.001), and category 3.51 – 3.75 (OR = 4.68, CI = 2.84 – 7.73; P < 0.001). We found no evidence of significant association between gender and UKDI score, and neither between accreditation ranking and UKDI score. Conclusion: Factors significantly associated with UKDI score were GPA. Factor that has the strongest association with UKDI score was clinical year GPA. Medical knowledge obtained when studying cases during clinical year in medical school can be strengthened by the guidance of mentor and clinical supervisors in order to achieve better UKDI results.
