Use of statin drugs was associated with improved mortality in older nursing home residents, regardless of dementia status, a new study showed.
The study is among the first to explore whether statin use in older nursing home residents offers a mortality benefit, especially among individuals with dementia, a group largely excluded from earlier statin trials.
Investigators’ analysis of 4 years of data on nearly 300,000 nursing home residents revealed that statin use was associated with a 40% lower risk for all-cause mortality than statin nonuse in those without dementia and a 20% lower risk in those with dementia.
“These findings may provide evidence that supports the continued use of statins in older nursing home patients with multiple medical conditions,” wrote lead author Julie Lorraine O’Sullivan, PhD, of the Charité–Universitätsmedizin Berlin, Freie Universität Berlin, German Center for Mental Health, Berlin, and colleagues.
The study was published online on February 27 in Neurology.
Understudied Population
Statins are the first-line treatment for preventing atherosclerotic cardiovascular disease (ASCVD), but they are also known to carry risks to patients who are frail or care-dependent. Many prior clinical trials excluded older participants with multiple comorbidities, especially those with dementia. So, evidence regarding the drugs’ efficacy in this population was lacking.
Investigators retrospectively examined 5 years of claims data from a German health and long-term care insurance provider on 282,693 nursing home residents (mean age, 83 years) who had used statins consecutively for ≥ 6 months.
Researchers used propensity score matching in 96,162 individuals to adjust for potential imbalances in the distribution of covariates (eg, age, sex, atrial fibrillation, ASCVD, and other conditions, as well as medications) and to reduce bias. Cox regression models were similarly adjusted for these factors, as well as care level. Residents were followed for an average of 2 years.
There were 54,269 recorded deaths during the study period, with most patients requiring a high level of care and 65% with dementia.
Statin use was associated with lower all-cause mortality in residents with dementia (hazard ratio [HR], 0.80, P < .001) and those without dementia (HR, 0.73; P < .001) compared with nonusers. The benefits remained consistent even after excluding participants with a history of ASCVD and across subgroups stratified by age sex, care level, and dementia type.
Limitations included the potential for unknown confounders and a lack of information about previous statin use, smoking and sedentary behavior, and the cause of mortality.
“Although our findings suggest the benefits of statins ... it is vital to acknowledge the need for further research to understand the underlying mechanism and the need for replication of our results to understand the potential risks before making recommendations to clinicians and families regarding statin therapy,” investigators wrote.
‘First Step’
In an accompanying editorial, Ariela R. Orkaby, MD, MPH, assistant professor of medicine, Brigham and Women’s Hospital, Harvard Medical School, Boston, called the study a “first step” to a better understanding of statin use in an understudied population.
“These findings build on a limited body of observational evidence for statin use in high-risk older adults, which has generally demonstrated protective associations for statins and mortality, including those with dementia and frailty, although nursing home status has not been specifically explored,” Dr. Orkaby wrote.
Perhaps more important than gaining information about statins’ effect on mortality risk in older people with dementia may be a better understanding of how the drugs might improve quality of life by reducing the risk for stroke or other cardiovascular events.
“It may be time to reconsider the broad recommendations to avoid or deprescribe statins in nursing home residents and rather invest in high-quality evidence to guide the care of this vulnerable population. After all, a lack of evidence does not imply benefit or harm, rather a need for more data,” Dr. Orkaby added.
The research was funded by Stiftung Charité; Dr. O’Sullivan and coauthors reported no relevant financial relationships. Dr. Orkaby received funding from a VA CSR&D CDA-2 award.
