Progressive disclosure cases: The design and evaluation of use in multiple therapeutics courses

Case-based learning is used frequently throughout pharmacy education. Although beneficial, stand-alone cases may result in segmented learning that does not simulate realistic longitudinal patient care. We report the development, implementation, and evaluation of a longitudinal progressive disclosure case surrounding a single patient spanning two different therapeutics courses.

A patient case was developed surrounding topics in two third professional year therapeutics courses occurring sequentially in the same semester. Changes to the patient's status were provided to students longitudinally via "disclosures." Students were assessed via quizzes and written assessment and plans. Students completed four perceptions of confidence surveys via a four-point Likert Scale. Surveys included questions surrounding confidence in areas of the pharmacists' patient care process (PPCP) before and after courses utilizing the progressive disclosure case. Case assessment grades were used to evaluate the impact on student performance on course examinations. Students also completed a survey on final perceptions of the activity.

Seventy students were enrolled in the two courses participating in the progressive disclosure case and there were 50 (71.4%) matched, completed surveys completed for analysis. Significant improvements were seen in several questions surrounding confidence in the areas of the PPCP between the beginning and conclusion of courses that contained the progressive disclosure case. No correlation between case activity grades and examination performance was found.

Overall, student confidence in patient care skills associated with information collection, assessment, plan design, and monitoring improved with the use of progressive disclosure cases within two sequential therapeutics courses.
