title: Long-term effects of a multifaceted intervention to encourage the choice of the oral route for proton pump inhibitors: an interrupted time-series analysis.
abstract: OBJECTIVE
  Drugs are often given intravenously even when the patient is able to swallow and when an oral form would be more cost-effective.
  
  
  METHODS
  Evaluation of the impact of a multifaceted intervention on the early switch from intravenous to oral administration of proton pump inhibitors (PPI) in a hospital setting. The interrupted time series of intravenous PPI consumption was analysed.
  
  
  METHODS
  At a French University Hospital, the Drug Committee, composed of multidisciplinary pharmacy and medical staff, addressed the issue of increasing consumption of intravenous PPI drugs (May 2003).
  
  
  METHODS
  Letters to department heads, academic analyses from members of the Drug Committee, paper reminders at the point of care and audit-feedbacks by pharmacists. Monitoring of consumption and repeated reminder letters were planned. EFFECT OF CHANGE: The consumption of PPI was stable before the first intervention (mean level: 954 units/month). An immediate decrease occurred after the first Drug Committee letter (30% relative reduction, 95% CI -16% to -46%; p<0.001) with a significant trend change during the first multifaceted intervention (-24 units/month, 95% CI -42 to -7; p = 0.007). After the end of the outreach visits (July 2004), the consumptions increased (+32 units/month, 95% CI: 14 to 50, p<0.001). The second intervention had no significant impact.
  
  
  CONCLUSIONS
  A complex intervention (audit, feedbacks, outreach visits) had an effect on practice. It was not sustained even after a less resource-intensive intervention. Other types of interventions are needed that could be continuously implemented to improve ordering practices long term.
