The Effect of Prerequisite Pharmacodynamics Course Timing on Student Performance in Pharmacotherapy Courses.
Objective. To evaluate the impact that decreasing the time from 12 to three months between prerequisite pharmacodynamics courses and their corresponding pharmacotherapy courses had on overall student performance in the pharmacotherapy courses measured by course examination scores. Methods. Two cohorts of second-professional year (P2) and third professional year (P3) classes, respectively, following different curriculum plans, simultaneously took two pharmacotherapy courses (infectious disease and neoplastic disease). Admission data (age, gender, prior bachelor's degree status, grade point average (GPA), Pharmacy College Admission Test (PCAT) score, and interview score) were collected to establish baseline characteristics between the two cohorts. Examination scores in the corresponding prerequisite pharmacodynamics and pharmacotherapy courses were also collected. The variable was the difference in time each cohort experienced between the prerequisite pharmacodynamics courses and the subsequent pharmacotherapy courses. Results. No difference was found in baseline admission characteristics between the two cohorts, except for increased average age, which favored the P2 cohort. In the infectious disease pharmacotherapy course, the P3 cohort performed better than the P2 cohort as measured by average examination scores. In the neoplastic disease pharmacotherapy course, the P3 cohort also achieved significant higher average examination scores than the P2 cohort. The P3 cohort achieved higher overall scores than the P2 cohort in both courses despite a longer interval between the applicable pharmacodynamic and pharmacotherapy courses (12 months vs 3 months, respectively). Conclusion. Shortening the time interval from 12 months to three months between prerequisite and requisite courses did not result in improved, or even equivalent, academic performance relative to the P2 cohort that had only a 3-month interval between courses. Placing like content closer together, as the only intervention, is not enough to ensure improved student performance measured by examination scores in corresponding requisite courses.
