RESUMO
PURPOSE: To compare the prevalence of potentially inappropriate medication (PIM) in the elderly according to the PRISCUS list, STOPP criteria, and Beers criteria. Secondary, to describe the differences using the three criteria focused on the inappropriate prescription of psychotropic drugs in the elderly. METHODS: A retrospective study was performed at Severo Ochoa University Hospital. The study included 365 patients, aged 80 years and older, living in Madrid, Spain. RESULTS: 93.42% of patients received at least one PIM during hospitalization. Using the PRISCUS list, this changed from 32.6 to 2.7% at discharge. Applying STOPP criteria lowered the percentage from 65.20 to 10.95%, and with Beers criteria from 80.27 to 10.13. Lower Barthel index at admission was associated with an increased relative risk for receiving at least one PIM (OR 1.79, 95% CI 1.15-2.80, p = 0.024) using PRISCUS list as a tool in conjunction with STOPP criteria (OR 1.44, 95% CI 0.89-2.33, p = 0.037). Polypharmacy at admission predicted the presence of PIMs with STOPP criteria (OR 1.74, 95% CI 1.07-2.84, p = 0.001). Regarding psychotropic medicines, 208 patients (56.98%) received at least one psychotropic medicine during hospitalization. A total of 26.30% of patients were treated with psychotropic medicines, detected by the PRISCUS list, and 53.97% and 29.85% with STOPP and Beers, respectively. CONCLUSIONS: Explicit criteria are a useful tool for identifying during hospitalization of the elderly patients. As indicated by the results, new research is needed to carry out an adaptation in our country that includes an evaluation of the strengths of the three tools to decrease PIMs and improve prescription in the elderly.
