RESUMO
BACKGROUND AND OBJECTIVES: The elderly patient is particularly vulnerable to potentially inappropriate prescription (PIP) due to physiological reasons, comorbidity, polypharmacy or the different pharmacokinetics/pharmacodynamics of drugs. The aim of this study was to determine the prevalence of PIP according to the STOPP-START criteria in patients over 65 years admitted into a geriatric hospital, as well as to appraise its acceptance by geriatricians. MATERIAL AND METHODS: Retrospective observational study. Patients older than 65 years consecutively admitted to medium/long-stay units were included. The study information was obtained by reviewing the clinical record of the patients. The PIP according to the STOPP-START criteria were assessed by the geriatrician, who decided whether or not to modify the medication and recorded the reasons. RESULTS: 247 patients were included, mean age was 82.6 years (SD 7.3), 72.1% of patients were female and a median of 7 drugs (25-75 percentile: 4-9). 78.9% (95%CI: 73.3-83.9) of patients had at least one PIP STOPP-START at admission, 44.9% (95%CI: 38.6-51.4) PIP-STOPP and 59.5% (95%CI: 53.1-65.7) PIP-START. At hospital discharge, the prevalence of PIP-STOPP-START was 46.2% (95%CI: 39.8-52.6), 19.0% (95%CI: 14.3-24.5) of PIP-STOPP and 34.4% (95%CI: 28.5-40.7) PIP-START. CONCLUSIONS: The comprehensive geriatric assessment and the use of the STOPP-START criteria can significantly reduce the prevalence of PIP among patients admitted to a geriatric hospital. Nevertheless, issues such as frailty, multimorbidity and functional goals would be taken into account in the appropriateness of the prescription.
