Abstract

Aim: To examine the patterns of preventive medicines (PM) use in the last year of life of older adults. Methods: This study cohort included individuals (n = 99 809) aged ≥75 years who were in their last year of life. PM examined in this study included low-dose aspirin (≤325 mg/day), clopidogrel, dipyridamole, warfarin, dabigatran, statins and bisphosphonates. Logistic regression models examined the influence of age, sex, multimorbidity, socioeconomic status, and a diagnosis of cancer on the number and type of PM prescribed from 2007 to 2012. Results: The number of PM prescribed was higher for men compared with women (OR 1.11, 95% CI 1.08–1.14). Increasing age did not have an effect on the number of PM prescribed. The use of clopidogrel increased almost threefold from 2007 to 2012 (OR 5.53, 95% CI 4.61–6.65). In contrast, bisphosphonates use decreased significantly during the same period (OR 0.35, 95% CI 0.32–0.39). Individuals with a diagnosis of cancer had increased odds of PM utilization for antiplatelets, aspirin monotherapy and statins, which had remarkably high odds (OR 4.11, 95% CI 3.88–4.34, P < 0.001). Conclusions: The present explorative study highlighted that some PM, such as statins, continue to be prescribed until death, particularly those that might have been beneficial earlier in life, but have an uncertain or unfavorable risk–benefit ratio towards the end-of-life.
