Abstract
IntroductionBenzodiazepines are the most utilized anxiolytic and hypnotic drugs. The high consumption of benzodiazepines has been a concern due to reported side effects of long-term use and dependence. Portugal has the highest benzodiazepine utilization in Europe.ObjectivesTo analyze the change in general practitioners’ (GPs) benzodiazepine prescription pattern after an intervention period.MethodsAn educational session was delivered to a group of intervened GPs. The benzodiazepine prescription pattern of intervened group was compared to the pattern of a non-intervened matched group from the same region, and of another non-intervened matched group from a different region. The research time frame was 12 months before and after intervention. The analysis of the prescription trends used the defined daily dose (DDD) and defined daily dose per 1000 patients per day (DHD) methodology. The statistical methods consisted of segmented regression analysis.ResultsThere was a decrease in benzodiazepine prescription pattern of intervened GPs after intervention (P = 0.005). There was also a decrease in benzodiazepine prescription pattern for the non-intervened group from the same region (P = 0.037) and for the non-intervened group from a different region (P = 0.010). Concerning an analysis by gender, female gender prescribed a higher amount of benzodiazepines. The intervened female gender prescribers presented the highest decrease in prescription trend after intervention (P = 0.008).ConclusionsIntervention was effective in reducing benzodiazepine prescription after intervention. It demonstrates that a single intervention has a positive impact on improving prescription trends. The replication of this intervention might be an opportunity for changing the worrying benzodiazepine utilization in Portugal.Disclosure of interestThe authors have not supplied their declaration of competing interest.
