Designing an electronic medication reconciliation system.

Unintended medication discrepancies at hospital admission and discharge potentially harm patients. Explicit medication reconciliation (MR) can prevent unintended discrepancies among care settings and is mandated by JCAHO for 2005. Enterprise-wide, we are linking pre-admission and discharge medication lists in our outpatient electronic health records (EHR) with our inpatient order entry applications (OE) - currently not interoperable - to support MR and inform the development of comprehensive MR among hospitalized patients.

How well do second-year students learn physical diagnosis? Observational study of an Objective Structured Clinical Examination (OSCE).

BACKGROUND: Little is known about using the Objective Structured Clinical Examination (OSCE) in physical diagnosis courses. The purpose of this study was to describe student performance on an OSCE in a physical diagnosis course. METHODS: Cross-sectional study at Harvard Medical School, 1997-1999, for 489 second-year students. RESULTS: Average total OSCE score was 57% (range 39-75%). Among clinical skills, students scored highest on patient interaction (72%), followed by examination technique (65%), abnormality identification (62%), history-taking (60%), patient presentation (60%), physical examination knowledge (47%), and differential diagnosis (40%) (p <.0001). Among 16 OSCE stations, scores ranged from 70% for arthritis to 29% for calf pain (p <.0001). Teaching sites accounted for larger adjusted differences in station scores, up to 28%, than in skill scores (9%) (p <.0001). CONCLUSIONS: Students scored higher on interpersonal and technical skills than on interpretive or integrative skills. Station scores identified specific content that needs improved teaching.

The relationship between second-year medical students' OSCE scores and USMLE Step 1 scores.

The relationship between objective structured clinical examinations (OSCEs) and standardized tests is not well known. We linked second-year medical students' physical diagnosis OSCE scores from 1998, 1999 and 2000 (n = 355) with demographic information, Medical College Admission Test (MCAT) scores, and United States Medical Licensing Examination (USMLE) Step 1 scores. The correlation coefficient for the total OSCE score with USMLE Step 1 score was 0.41 (p < 0.001). Two of 7 skills areas-diagnosis and identification of abnormality-were significant multivariate correlates of USMLE Step 1 score. OSCE station scores accounted for approximately 22% of the variability in USMLE Step 1 scores. A second-year OSCE in physical diagnosis is correlated with scores on the USMLE Step 1 exam, with skills that foreshadow the clinical clerkships most predictive of USMLE scores. This correlation suggests predictive validity of this OSCE and supports the use of OSCEs early in medical school.

Design and implementation of an application and associated services to support interdisciplinary medication reconciliation efforts at an integrated healthcare delivery network.

Confusion about patients' medication regimens during the hospital admission and discharge process accounts for many preventable and serious medication errors. Many organizations have begun to redesign their clinical processes to address this patient safety concern. Partners HealthCare, an integrated delivery network in Boston, Massachusetts, has answered this interdisciplinary challenge by leveraging its multiple outpatient electronic medical records (EMR) and inpatient computerized provider order entry (CPOE) systems to facilitate the process of medication reconciliation. This manuscript describes the design of a novel application and the associated services that aggregate medication data from EMR and CPOE systems so that clinicians can efficiently generate an accurate pre-admission medication list. Information collected with the use of this application subsequently supports the writing of admission and discharge orders by physicians, performance of admission assessment by nurses, and reconciliation of inpatient orders by pharmacists. Results from early pilot testing suggest that this new medication reconciliation process is well accepted by clinicians and has significant potential to prevent medication errors during transitions of care.
