Abstract
BACKGROUND: Proton pump inhibitors (PPIs) are indicated for a restricted number of clinical conditions, and their misuse can lead to several adverse effects. Despite that, the proportion of overuse is alarmingly high.
OBJECTIVE: To test the efficacy of a multifaceted strategy in order to achieve a significant reduction of new PPI prescriptions at discharge in hospitalized patients.
DESIGN: Multicenter longitudinal quasi-experimental before-and-after study conducted from July 1st, 2014 to June 30th, 2017.
PARTICIPANTS: 44,973 admissions in a network of 5 public teaching hospitals of the Italian-speaking region of Switzerland.
INTERVENTION: Multifaceted strategy consisting in a continuous transparent monitoring-benchmarking and in capillary educational interventions applied in the internal medicine departments. To confirm the causality of the results we monitored the trend of new PPI prescriptions in the, not exposed to the intervention, surgery departments of the same hospital network.
MAIN MEASURES: New PPI prescriptions at hospital discharge.
KEY RESULTS: Over the 36month study period 44,973 patient files were analyzed. At admission, comparing internal medicine vs. surgery departments, 44.9% vs. 23.3% of patients were already being treated with a PPI. The annual rate of new PPI prescriptions, for internal medicine showed a decreasing trend: 19, 19, 18, 16% in years 2014, 2015, 2016, 2017, respectively (p<0.001, 2014 vs. 2017; p-for-trend <0.001), while an increasing rate was found in the surgery departments in the same years: 30, 29, 36, 36%, respectively (p<0.001, 2014 vs. 2017; p-for-trend <0.001). The case mix was significantly associated with the probability of new PPI prescriptions in both departments (OR1.35, 95% CI 1.26-1.44 for internal medicine and 1.24, 95% CI 1.19-1.30 for surgery).
CONCLUSIONS: The introduction of a multifaceted intervention significantly reduced the time trend of PPI prescriptions at hospital discharge in internal medicine departments. Further studies are needed to confirm whether the strategy proposed could contribute to optimize the in-hospital drug prescription behavior in other healthcare settings as well.
