Objectives The aim of this study is to analyze the association between the degree of frailty and inappropriate prescribing patterns at admission to an Acute Care of the Elderly Unit (ACE Unit). Methods Prospective observational study conducted in the ACE Unit of an acute hospital in Barcelona city between June and August 2021. Epidemiological and demographic data were collected during hospitalization. Comprehensive geriatric assessment was performed on admitted patients. We recorded frailty (FRAIL scale), extreme polypharmacy (10 or more drugs), central nervous system potentially inappropriate medications‐PIMs (STOPP‐CNS or group D), cardiovascular potential prescribing omissions‐PPOs (START‐CV or group A), and anticholinergic burden using the drug burden index (DBI). Results Ninety‐three patients were included, of whom 48 (51.6%) were male, with a mean age of 82.83 (SD 7.53) years. The main diagnosis upon admission was heart failure in 34 patients (36.6%). Frail patients were older, with more dependence of activities of daily living and more comorbidity than non‐frail patients. Additionally, frail patients demonstrated more omissions according to the START‐A criteria. No statistically significant differences were observed in term of extreme polypharmacy, PIMs, or anticholinergic burden. Conclusions In the current study we found an association between frailty and inappropriate prescribing, specifically with regard to omissions using the START criteria for the cardiovascular system (group A). Notably, frail patients exhibited more omissions compared to their non‐frail counterparts, and this difference was statistically significant. In this observational study of 93 elderly patients in an acute of the elderly unit in Barcelona, we analyzed the association between frailty and inappropriate prescribing. Frail individuals exhibited a significant association with cardiovascular medication omissions. These findings highlight the need for tailored interventions to address inappropriate prescribing, particularly in frail older adults, to improve their health care outcomes.
