Background • Potentially inappropriate medications (PIMs) are those medications whose adverse risks exceed their health benefits1 • PIMs use in the community-dwelling elderly is associated with negative patient health outcomes2,3 • Using the Beers Criteria, preliminary data in the Emilia-Romagna Region, Italy, showed that 1 out of 5 elderly patients are subject to PIMs in ambulatory settings4 1) Stuck AE, Beers MH, Steiner A, et al.

Objective • To enhance physicians’ knowledge of prescribing for the elderly and improve the quality of prescribing in the primary care setting in the Local Health Unit (LHU) of Parma, Italy
Methods • A 3-year, multi-phase prospective demonstration project targeting all 303 general practitioners (GPs) in the LHU of Parma, Italy, was established in 2007 Key Elements of multi-phase Intervention: Q1-Q3 2007 Q4 2007 Q1-Q3 2008 Development of PIMs list Dissemination of PIMs list to GPs & annual review of PIMs prevalence data Dissemination of alternative list of drugs to GPs 2007 Q4 2009 Q1-Q3 2009 Q4 2008 Case studies presentation & annual review of PIMs prevalence data Development of case studies on PIMs Annual review of PIMs prevalence data 2010
*The following selected drugs were included in the analysis: risperidone, clozapine, olanzapine, quetiapine, aripiprazole 5) Maio V, Del Canale S, Abouzaid S, et al.

Summary • A quality intervention program looking at improving knowledge in primary care physicians on prescribing for the elderly patients resulted in a substantial reduction of the rate of PIMs • The greatest impact was seen in users of digoxin and NSAIDs, with a significant potential benefit for patients
Limitations • PIMs with a low rate of use at baseline may be impossible to lower any further and may diminish the overall impact of our intervention • The study does not measure the impact of the intervention on other healthcare resource use or patient outcomes
Future Directions • Additional analyses should be performed to further investigate: • Which physicians were less prone to change prescribing and use results to design targeted educational interventions • Whether the observed change may be retained over time
