Analysis of self-reported confidence in independent prescribing among osteopathic medical graduating seniors.

Context: Prescribing medications is one of the physicians' most important professional activities throughout their careers. Lack of confidence and competency to prescribe may lead to preventable medical errors. The prevalence of prescription errors among new graduate physicians has been widely studied. Studies have linked this to inadequate foundational pharmacology education and work environment, among other factors. Suggestions were made for different educational interventions to increase the physicians' confidence and competency in prescribing to reduce the risk of medical errors. However, many of these studies were about students or graduates of medical schools other than osteopathic medical schools.

Objectives: This study analyzed the self-reported confidence of graduating seniors in the United States osteopathic medical schools in their current ability to prescribe safely and independently and the possible associated factors.

Methods: This study analyzed secondary data on the graduating seniors' surveys published by the American Association of Colleges of Osteopathic Medicine (AACOM) from the 2012/2013 to 2020/2021 academic years. Data were analyzed utilizing SPSS version 26.0 and MedCalc version 22.009, and statistical inferences were considered significant whenever p≤0.05.

Results: The aggregated data show that 38,712 Doctor of Osteopathic Medicine (DO) seniors responded to the AACOM survey, representing 72.1 % of expected graduates during the study period. Most of the DO graduating seniors (70.8 %) reported feeling confident in their current abilities to independently write safe and indicated orders and to prescribe therapies or interventions in various settings. The percentage of respondents who perceived the time devoted to clinical pharmacology instruction as appropriate increased systematically over these reported years. A positive correlation was found between the percentage of students who reported the time dedicated to clinical pharmacology as excessive and the percentage of students who reported being confident in prescribing. A statistically significant positive correlation was found between the percentage of students who agreed that the first two years of medical school were well organized and the percentage of students who reported being confident in prescribing. A statistically significant correlation was found between the percentage of students who agreed with statements about frequent interactions with the attendee, testing at the end of each rotation, and being prepared for Comprehensive Osteopathic Medical Licensing Examination Level 2-Cognitive Evaluation (COMLEX Level 2-CE) during the required clerkships and the percentage of students who reported being confident in independent prescribing.

Conclusions: During this study period, most osteopathic medical graduating seniors (70.8 %) felt confident about their current prescribing abilities; the rest did not, which can increase the risk of preventable medical errors. The prescription confidence may be boosted by more organization for the first 2 years, increasing the time devoted to clinical pharmacology education, and developing more interactive courses during the required clerkships in clinical education.
