ObjectivesTo evaluate a clinical pharmacist's inclusion in emergency department (ED) care in terms of the effect on on 30-day revisits after discharge from the ED and patient satisfaction.Material And MethodsRandomized, controlled parallel-group pragmatic trial in a university hospital ED. Recruited patients were randomly assigned to a control group for standard care only or an intervention group to receive standard care plus the attention of a clinical pharmacist integrated into the care team to optimize the selection and evaluation of medications and provide pharmacotherapeutic education on the patient's discharge. The primary outcome was unplanned revisits within 30 days after discharge because of the same complaint that led to the initial ED visit. Between-group differences were analyzed with Kaplan-Meier survival curves and log-rank tests. The association between the intervention and time to the outcome event was explored with multivariate Cox proportional hazard regression analysis.ResultsA total of 1001 patients were enrolled (intervention, 500; control, 501). Patients in both groups were similar. A majority were women (61.5%), and the median age (interquartile range) was 51 years (33-65 years). The pharmacist's intervention significantly reduced the number of 30-day revisits to any ED: 25 (6.3%) revisited vs 66 (16.7%) in the control group. The adjusted hazard ratio (aHR) was 0.29 (95% CI, 0.17-0.50). Fifteen patients (3.0%) from the intervention group revisited the same ED vs 32 (6.5%) from the control group (aHR, 0.46 [95% CI, 0.24-0.87]). More patients expressed satisfaction in the intervention group (87.2%) than in the control group ( 83.2%) (P .05).ConclusionIncluding a clinical pharmacist in ED care substantially reduces the number of 30-day revisits and increases patient satisfaction.
