ABSTRACT

Introduction: Many older adults have multiple medical conditions that require medical attention, exposing them to polypharmacy and to a higher increase in prescribing potentially inappropriate medications. These situations may cause adverse drug reactions, longer hospital stays, and death. The prevalence of polypharmacy in our country is estimated at 55% and inappropriate prescribing of medications of 30%. Objective: To determine the prevalence of polypharmacy and potentially inappropriate drug prescription in older patients hospitalized for cardiovascular diseases. Material and methods: Patients older than 70 years from a tertiary level hospital admitted to cardiology and angiology were included, from the period 2013-2014. Fragility status, polypharmacy, and drug prescription based on the Beer’s criteria were established. The results were analyzed using descriptive statistics. For inferential analysis, cross tabulations with Pearson χ² were used. Results: 446 patients where included, with female predominance of 56% (mean age 76.6 ± 5.9 years). The prevalence of fragility was 35.7%, polypharmacy 84.5%, and inappropriate prescription of drugs 48.9%. Coefficient correlation between inappropriate prescription of drugs and polypharmacy was p = 0.001. Conclusions: The prevalence of polypharmacy and inappropriate prescription of drugs was higher than reported previously, which shows the situational diagnosis in this tertiary level hospital, considering a population with high cardiovascular risk.
