Evaluation of a new integrated discharge prescription form.

OBJECTIVE: To determine whether a new discharge prescription form which integrates admission medications, in-hospital changes, and discharge medications could enhance the accuracy of information in patient profiles in community pharmacies after hospital discharge.
DESIGN: Nonrandomized, prospective, multi-site study. SETTINGS: Internal medicine wards of the three teaching hospitals (1200 beds) of the Centre Hospitalier de l'Université de Montréal.
SUBJECTS: Patients admitted to the internal medicine wards between January 4 and 31, 1999, at St.-Luc and Notre-Dame Hospitals formed the control group and received a usual discharge form (UD). Those admitted between February 1 and 28,1999, received the new discharge prescription form (DPF) capturing the list of admission medications and revisions during hospitalization; they served as the experimental group.
METHODS: Patient profiles were reviewed to calculate conformity rates of community pharmacy patient profiles after discharge and the rate of overall conformity for each group in the study. Each drug in the patient profile was assessed according to six criteria. Healthcare providers' satisfaction with the DPF was assessed via a written questionnaire.
RESULTS: Eighty-nine patients and 669 discharge medications were studied. The patient profiles had a higher conformity rate in the DPF group than in the UD group (82% vs. 40%; p < 0.001); improvement could be attributed to higher conformity rates, particularly for two criteria (medications stopped in hospital and dose changes in hospital).
CONCLUSIONS: Integration of admission medications, in-hospital changes, and discharge medications on a single form increases the conformity rates of community pharmacy patient profiles after hospitalization. This tool is well accepted by both pharmacists and physicians and may lead to a major decrease in drug-related problems.
