Older inpatients aged 65 and overaccount now for half of acute care hospitals’ admissions andbed-days. However, frailty, chronic multimorbidity, disability,polypharmacy and the complexity of care expose elderlyinpatients to an increased risk of potentially preventableadverse events (PPAEs).According to the Swiss Health2020 Reform and the FrenchNational Health Strategy that both promote safety measure-ments in inpatient and outpatient settings, we aim todevelop and validate in-hospital and post-hospitalelderly patient safety indicators (EPSIs) using hospitaladministrative data linked to insurance claims data toinform health policies, help patients’ choice, and improveequity and efficiency.MethodsStudy population will consist of individuals aged 65 or olderwho were hospitalised in acute care between 2012 and 2014and who were insured at least one year before theirhospitalisation. Swiss data will be extracted from a dataset of1.2 million persons (15% of the Swiss residents) who wereinsured by the Helsana Group. French data will include allbeneficiaries of the general health insurance scheme (70% ofthe French residents).The development and validation process will comprise a 6-stepstrategy: 1) a systematic literature review, 2) structured expertpanel reviews, 3) empirical measures of the adjusted EPSIs athospital and territorial level using Swiss and French linkeddatabases, 4) a 4-step validation process, 5) the study of EPSIs’temporal trends and geographical variations, 6) graphicalanalyses of the results for hospital/territorial profiling andbenchmarking.ConclusionsEPSIs based on administrative linked data should provide validand reliable tools for monitoring PPAEs affecting elderlypatients hospitalised in acute care and for comparing elderlypatients’ safety across Swiss and French hospitals or healthterritories.Key messages Patient safety indicators based on hospital administrativedata linked to insurance claims data could be used toevaluate elderly patients’ safety both in hospital and inprimary care settings Elderly patient safety indicators (EPSIs) based on hospitaladministrative data linked to insurance claims data shouldbe more reliable and valid than EPSIs based on hospitaladministrative data alone414 European Journal of Public Health, Vol. 25, Supplement 3, 2015
