OBJECTIVETo summarise the evidence on interventions aimed at optimising the drug treatment of hospitalised elderly patients. MATERIAL AND METHODSWe conducted a search in the main medical literature databases, selecting prospective studies of hospitalised patients older than 65 years who underwent interventions aimed at optimising drug treatment, decreasing polypharmacy and improving the medication appropriateness, health outcomes and exploitation of the healthcare system. RESULTSWe selected 18 studies whose interventions consisted of medication reviews, detection of predefined drugs as potentially inappropriate for the elderly, counselling from a specialised geriatric team, the use of a computer support system for prescriptions and specific training for the nursing team. Up to 14 studies assessed the medication appropriateness, 13 of which showed an improvement in one or more of the parameters. Seven studies measured the impact of the intervention on polypharmacy, but only one improved the outcomes compared with the control. Seven other studies analysed mortality, but none of them showed a reduction in that rate. Only 1 of 6 studies showed a reduction in the number of hospital readmissions, and 1 of 4 studies showed a reduction in the number of emergency department visits. CONCLUSIONSDespite the heterogeneity of the analysed interventions and variables, we obtained better results in the process variables (especially in medication appropriateness) than in those that measured health outcomes, which had greater variability.
