Significant differences in written assessments as a result of a blended learning approach used in a clinical examination course in internal medicine: a randomized controlled pilot study.

Background: Taking a medical history and performing a physical examination represent basic medical skills. However, numerous national and international studies show that medical students and physicians-to-be demonstrate substantial deficiencies in the proper examination of individual organ systems. Aim: The objective of this study was to conduct a randomized controlled pilot study to see if, in the context of a bedside clinical examination course in internal medicine, an additional app-based blended-learning strategy resulted in (a) higher satisfaction, better self-assessments by students when rating their history-taking skills (b1) and their ability to perform physical examinations (b2), as well as (c) higher multiple-choice test scores at the end of the course, when compared to a traditional teaching strategy. Methods: Within the scope of a bedside course teaching the techniques of clinical examination, 26 students out of a total of 335 students enrolled in the 2012 summer semester and 2012/2013 winter semester were randomly assigned to two groups of the same size. Thirteen students were in an intervention group (IG) with pre- and post-material for studying via an app-based blended-learning tool, and another 13 students were in a control group (CG) with the usual pre- and post-material (handouts). The IG was given an app specifically created for the history-taking and physical exam course, an application program for smartphones enabling them to view course material directly on the smartphone. The CG received the same information in the form of paper-based notes. Prior to course begin, all of the students filled out a questionnaire on sociodemographic data and took a multiple-choice pretest with questions on anamnesis and physical examination. After completing the course, the students again took a multiple-choice test with questions on anamnesis and physical examination. Results: When compared to the CG, the IG showed significantly more improvement on the multiple-choice tests after taking the clinical examination course (p=0.022). This improvement on the MC tests in the IG significantly correlated with the amount of time spent using the app (Spearman's rho=0.741, p=0.004). Conclusion: When compared to conventional teaching, an app-based blended-learning approach leads to improvement in test scores, possibly as a result of more intensive preparation for and review of the clinical examination course material.      «
