Impact of hospitalization on potentially inappropriate prescribing: a cross-sectional study in an acute geriatric hospital in Lithuania

摘要

Background Potentially inappropriate prescribing is frequent among elderly patients admitted to hospitals in many countries. However, the impact of hospitalization on potentially inappropriate medications and potential prescribing omissions has not been studied in depth. Objective This study aimed to investigate the impact of hospitalization on the prevalence of potentially inappropriate medications and potential prescribing omissions among elderly patients admitted to and discharged from an acute care geriatric clinic. Setting Geriatric wards of a teaching hospital in Lithuania. Method This observational cross-sectional study included 76 subjects aged >= 65 years. The Beers 2015 Criteria, the EU(7)-PIM list, and the second versions of the Screening Tool of Older Person's Prescriptions and the Screening Tool to Alert doctors to Right Treatment were applied to detect potentially inappropriate medications and potential prescribing omissions. Data were extracted from patient's medical records. Main outcome measure Prevalence of potentially inappropriate medications and potential prescribing omissions on hospital admission and hospital discharge. Results Potentially inappropriate medications were identified among 44.7% to 69.7% of patients upon hospital admission and 59.2% to 72.4% upon hospital discharge. The prevalence of potentially inappropriate medications had increased upon discharge based on each set of criteria. Potential prescribing omissions were detected in 93.4% of patients at admission and 96.1% of patients at discharge. Conclusion Potentially inappropriate prescribing is highly prevalent among older patients hospitalized in the studied setting in Lithuania and hospitalization had not reduced potentially inappropriate medications and potential prescribing omissions. There is a need for interventions aiming to reduce potentially inappropriate prescribing among elderly patients.
