Overview

Older people often need comprehensive treatment, including many medications, and polypharmacy is common. The aims of this cross-sectional investigation were to examine the potentially inappropriate medication during the hospitalization and to identify the factors that may influence such inappropriateness among elderly in Italy. A sample of 605 individuals aged 65 years and older admitted in non-academic public acute care hospitals was randomly selected. Prescription of inappropriate medications were evaluated during the period from the day of admission to a randomly preselected day (index day). Beers Criteria were used to evaluate appropriateness. At least one potentially inappropriate medication prescription from the day of hospital admission to the index day has been observed in 188 patients (31.1%), and respectively 84.1% and 15.9% of them had received one or two inappropriate medications. A total of 15 medications was prescribed inappropriately to these 188 patients, for 215 times with a total of 1143 doses. The multivariate logistic regression analysis revealed that the significant predictors for having at least one potentially inappropriate medication prescription during the hospitalization were: patients having an elementary education level, a lower pre-admission performance-based measure of basic activities of daily living, having received an inappropriate drug before the hospitalization, a hospital stay in the general and in the specialties surgical wards, a longer length of hospital stay from the admission to the index day, and having received a higher number of drugs from the day of the hospital admission to the index day. The most prevalent inappropriate medications administered were ketorolac (27.4%), amiodarone (19.1%), and clonidine (11.2%). This study supports the need for clinical guidelines implementation to assist physicians in choosing the most appropriate drugs for the elderly and for effective education of all physicians.
