Prevalence of Preventive Cardiovascular Medication Use In Nursing Home Residents. Room for Deprescribing? The SHELTER Study

Introduction: In nursing home (NH) residents with a very short life expectancy, the benefits of preventive cardiovascular medication maintenance are questionable. Objective: To assess the prevalence of 4 classes of preventive cardiovascular medication (PCM) in NH residents, and to explore differences of prevalence across length of stay, mortality risk, cognitive impairment, functional disability, and across countries. Methods: A 12-month prospective cohort study was conducted in 57 NHs in 8 countries (Czech Republic, England, Finland, France, Germany, Italy, The Netherlands, and Israel). We assessed the prevalence at first measurement of 4 classes of PCM: oral anticoagulants (OAC), platelet aggregation inhibitor (PAI), antihypertensive (AHT), and lipid-modifying agent (LMA), in older (60+ years) residents with valid medication assessments. The PCM prevalence was compared across the length of stay (short <60 days, mid, long >12 months), health instability as defined by Changes in Health, End-Stage Disease, Signs, and Symptoms Scale (CHESS) > 3, cognitive impairment by Cognitive Performance Scale (CPS) > 2, and functional disability was measured using the Activities of Daily Living Hierarchy Scale (ADLH) ≥5. Results: Of the 3759 eligible residents, 2175 (57.9%) used at least 1 PCM. The prevalence of the 4 groups of PCM: OAC, PAI, AHT and LMA were 5.6%, 34.9%, 35.7%, and 10.4%, respectively. PCM use was lower in long-stay residents versus mid-stay: 56.0% vs. 62.7%, in cognitively impaired residents (47.1% vs. 67%), in residents with a high mortality risk (47.4% vs. 58.6%), and in residents with a high ADLH score (48.6% vs 64.0%). Conclusion: Although the prevalence of PCM use was lower in long-stay, cognitively impaired residents, persons with a high mortality risk, and residents with more functional disabilities, there seems to be room for deprescribing.
