Improving the quality of adverse drug reaction reporting by 4th-year medical students.
PURPOSE: Evaluate whether a 15-minute lecture intervention will improve adverse drug reaction reporting quality on standard MedWatch forms. METHODS: Seventy-eight 4th-year medical students were randomized to intervention 'Group-A' or non-intervention 'Group-B' on the first day of a required five-day clinical pharmacology rotation. Group-A participants attended a 15-minute lecture on completing a MedWatch form with quality information considered by the Food and Drug Administration as critical to adequate adverse drug reaction reporting. Group-B participants did not attend this lecture. Both groups then watched a standardized patient interview of a recognizable adverse drug reaction and completed MedWatch forms. Four Safety Evaluators from the Food and Drug Administration (FDA) rated student responses in a blinded fashion for the primary efficacy variable of Overall Impression and six informational domins using a standardized data quality analysis form that was developed within the Office of Postmarketing Drug Risk Assessment of the FDA. RESULTS: Seventy-eight MedWatch forms were evaluated (Group-A = 40, Group B = 38). Overall MedWatch information quality scores for the intervention group were significantly higher than the non-intervention group (p < 0.004). CONCLUSIONS: As little as a 15-minute intervention can significantly improve the quality of adverse drug reaction reporting by 4th-year medical students. Academic medical centers should consider incorporating adverse drug reaction reporting curriculum into the clinical training of medical students.

Tardive dyskinesia risks and metoclopramide use before and after U.S. market withdrawal of cisapride.
OBJECTIVE: To assess risk factors for tardive dyskinesia (TD) in spontaneous reports of metoclopramide and TD and evaluate metoclopramide prescribing patterns before and after withdrawal of cisapride from the market in the United States. DESIGN: Retrospective and observational analyses. SETTING: International metoclopramide adverse event reports and domestic drug-use data for the continental United States. PATIENTS: Users of metoclopramide for 30 days or more who experienced adverse events reported as TD. INTERVENTIONS: Analyses of the Food and Drug Administration Adverse Event Reporting System (AERS) and IMS HEALTH data. MAIN OUTCOME MEASURES: Pharmacoepidemiological patterns in AERS reports and utilization data from IMS HEALTH. RESULTS: The case series comprised 87 reports of primarily older (mean+/-SD, 60+/-22 years ) women (67% of all cases). While average metoclopramide daily dose (33+/-14 mg) was within recommended product labeling limits, duration of use was considerably longer (753+/-951 days). Overall, 37% of the reports included concomitant drugs believed to be TD risk factors. Similarly, 18% of the reports noted comorbid diseases that are considered risk factors for development of TD. Metoclopramide utilization decreased following cisapride marketing in 1993 and increased following cisapride withdrawal in 2000. The majority (62%) of metoclopramide prescriptions were intended for women. Intended use overall increased with age and was highest in the seventh and eighth decades, with nearly one quarter of all utilization being in persons older than 70 years. CONCLUSION: Well-described TD risk factors were common in metoclopramide-associated TD reports. Given the cisapride market withdrawal and associated increased metoclopramide utilization, the incidence of TD may increase accordingly. TD risk factors relative to the intended benefit and duration of use should be considered in metoclopramide prescribing.
