Statin utilisation patterns in older Australians living in residential care: 1-year prevalence study

摘要

Despite controversy over the risks and benefits of statin therapy, statins continue to be commonly used medicines by older people. In a cohort study of participants aged 70 years (n = 540) living in residential care, Sydney, we found that the proportion of statin users decreased gradually from the baseline of 33.1% to 31.3% at 6 months (P = 0.13) and to 28.7% over 1 year (P = 0.002). Prevalence of statin use decreased with increasing age, with individuals aged 90 years being more likely to discontinue or deprescribe statins. The patterns of statin use did not change according to increasing baseline dose or baseline indication.
