The impact of the location and structure of an ambulatory rotation on cognitive knowledge and performance.

With the increasing shift to community-based ambulatory education, it is essential to gain a better understanding of the impact of these changes. To assess the impact of the location and structure of an ambulatory internal medicine clerkship rotation on cognitive knowledge and clinical performance, students were assigned to one of the following: (a) a multidisciplinary ambulatory clerkship (MAC), (b) the office of a community-based general internist, or (c) a university-based internal medicine ambulatory clinic. The groups were compared on the internal medicine clerkship examination and preceptor ratings controlling for introduction to clinical medicine course performance via analysis of covariance. MAC students were rated lower than the other two groups by their preceptors. There were no other statistically significant differences. The structure and location of the rotation had little impact on cognitive knowledge. The impact of the structure of the rotation on clinical performance is less clear suggesting that further research is needed.

Setting standards and defining quality of performance in the validation of a standardized-patient examination format.

PURPOSE: To evaluate whether written standards increase the reproducibility of a physician-facilitated station in an objective structured clinical examination (OSCE) designed to assess history, physical-examination, and communication skills. METHOD: The OSCE examination at the University of Texas Medical Branch-Galveston consists of ten eight-minute stations. Six of these stations consist of three History, Physical-examination, Problem-solving, and Plan (HPPP) station pairs. Each existing clinical-problem HPPP station was given to two content experts to develop standards for faculty rating scales appropriate for the evaluation of third-year medical students. Three pairs of faculty members were used to determine interrater reliability by scoring videotapes of three HPPP stations' presentation and problem-solving components. Faculty pairs scored tapes of 15 students without using standards and tapes of 15 students using the standards developed. Differences between the reliabilities without and with the standards were tested for significance using Fisher's R to Z transformation. The reproducibility and standard error of measurement (SEM) were extrapolated for increasing amounts of testing time. The HPPP component scores were also correlated with the written examination scores and preceptors' ratings. Data were obtained from the three HPPP stations used in the 1995-96 internal medicine clerkship SP examination. RESULTS: In all, 196 students completed the OSCE examination. The standards developed improved interrater reliability and reached statistical significance (p < .01) for one HPPP station. Reproducibility for the presentation and problem-solving components of the HPPP stations were > .80 after five hours of testing. The problem-solving component correlated at .37 and .19 with written examinations and with ward grades, respectively. CONCLUSION: The data from this study suggest that standards increase the reproducibility of presentation and problem-solving components of an OSCE to a level as high as, or higher than, that associated with the history, physical-examination, and communication components of traditional standardized-patient examinations.

Over-the-counter medications. Do you know what your patients are taking?

The pharmacopeia of over-the-counter (OTC) drugs is ever expanding, and many of these nonprescription agents cause a variety of adverse drug-drug and drug-patient interactions. It is therefore essential that physicians be aware of the more than 700 active ingredients available in OTC drugs at the local store and make a concerted effort to identify which ones their patients are taking. Healthcare providers also need to educate patients about the potential effects of OTC drugs and encourage them to consult either their physician or their pharmacist before attempting self-medication.
