Objectives To determine whether prescription opioid use is associated with higher dementia risk or greater cognitive decline. Design Prospective cohort study. Setting Group Health, an integrated healthcare delivery system. Participants Community-dwelling individuals aged 65 and older without dementia with at least 10 years of Group Health enrollment at baseline (N = 3,434; median age 74). Measurements The Cognitive Abilities Screening Instrument (CASI) was administered every 2 years. Low scores triggered detailed evaluation, and a multidisciplinary committee assigned dementia diagnoses. From computerized pharmacy data, cumulative opioid exposure was defined as total standardized doses (TSDs) dispensed over 10 years (excluding the most recent year because of possible prodromal symptoms). For comparison, use of nonsteroidal anti-inflammatory drugs (NSAIDs), characterized similarly, was examined. Dementia risk was analyzed using Cox proportional hazards models and CASI trajectory using linear regression models and generalized estimating equations. Results Seven hundred ninety-seven participants (23%) developed dementia over a mean follow-up of 7.3 years; 637 (19%) had possible or probable Alzheimer's disease. For cumulative opioid use, the hazard ratios (HRs) for dementia were 1.06 (95% confidence interval (CI) = 0.88-1.26) for 11 to 30 TSDs, 0.88 (95% CI = 0.70-1.09) for 31 to 90 TSDs, and 1.29 (95% CI = 1.02-1.62) for 91 or more TSDs, versus 0 to 10 TSDs. A similar pattern was seen for NSAID use. Heavier opioid use was not associated with more-rapid cognitive decline. Conclusion People with the heaviest opioid or NSAID use had slightly higher dementia risk than people with little or no use. These results may reflect an effect of chronic pain on cognition or residual confounding. Although opioids have other risks, little evidence of long-term cognitive harm specific to opioids was found.

Improving the quality of medication use and medication safety are important priorities for prescribers who care for older adults. The objective of this article was to identify four exemplary articles with this focus in 2020. We selected high‐quality studies that moved the field of research forward and were not merely replication studies. The chosen articles cover domains related to deprescribing, medication safety, and optimizing medication use. The first study, a noninferiority randomized clinical trial in England, evaluated whether antihypertensive medication reduction is possible without significant changes in systolic blood pressure control or adverse events over the 12‐week follow‐up (domain: deprescribing). The second study, a prospective cohort study of women at Kaiser Permanente Southern, California, examined the association between bisphosphonate use and atypical femur fracture (domain: medication safety). The third study examined the effectiveness and safety of a multifaceted antimicrobial stewardship and quality improvement initiative in reducing unnecessary antimicrobial use for unlikely cystitis cases in noncatheterized residents in 25 nursing homes across the United States (domain: optimizing medication use). Lastly, the fourth study, a population‐based cohort study in the United Kingdom, examined the association of tramadol use with risk of hip fracture (domain: medication safety). Collectively, this review succinctly highlights pertinent topics related to promoting safe use of medications and promotes awareness of optimizing older adults' medication regimens.

Background: Central nervous system (CNS)‐active medication use is an important modifiable risk factor for falls in older adults. A fall‐related injury should prompt providers to evaluate and reduce CNS‐active medications to prevent recurrent falls. We evaluated change in CNS‐active medications up to 12 months following a fall‐related injury in community‐dwelling older adults compared with a matched cohort without fall‐related injury. Methods: Participants were from the Adult Changes in Thought study conducted at Kaiser Permanente Washington. Fall‐related injury codes between 1994 and 2014 defined index encounters in participants with no evidence of such injuries in the preceding year. We matched each fall‐related injury index encounter with up to five randomly selected clinical encounters from participants without injury. Using automated pharmacy data, we estimated the average change in CNS‐active medication use at 3, 6, and 12 months post‐index according to the presence or absence of CNS‐active medication use before index. Results: One thousand five hundred sixteen participants with fall‐related injury index encounters (449 CNS‐active users, 1067 nonusers) were matched to 7014 index encounters from people without fall‐related injuries (1751 users, 5236 nonusers). Among CNS‐active users at the index encounter, those with fall‐related injury had an average decrease in standard daily doses (SDDs) at 12 months (−0.43; 95% CI: −0.63 to −0.23), and those without injury had a greater (p = 0.047) average decrease (−0.66; 95% CI: −0.78 to −0.55). Among nonusers at index, those with fall‐related injury had a smaller increase than those without injury (+0.17, 95% CI: +0.13 to +0.21, vs. +0.24, 95% CI: +0.20 to +0.28, p = 0.005). Conclusions: The differences in CNS‐active medication use change over 12 months between those with and without fall‐related injury were small and unlikely to be clinically significant. These results suggest that fall risk‐increasing drug use is not reduced following a fall‐related injury, thus opportunities exist to reduce CNS‐active medications, a potentially modifiable risk factor for falls.

Improving the quality of medication use and medication safety is an important priority for prescribers who care for older adults. The objective of this article was to identify key articles from 2018 that address these issues. In addition, we selected four of these articles to annotate, critique, and discuss their broader implications for clinical practice. The first study highlights a cluster‐randomized trial that utilized a pharmacist‐led education‐based intervention delivered to both patients and physicians to deprescribe four types of inappropriate medications (sedative‐hypnotics, first‐generation antihistamines, selective nonsteroidal anti‐inflammatory drugs, and glyburide). The second study, a nested case‐control study using data from within the UK Clinical Practice Research Datalink, examined the association between anticholinergic exposure, overall and by anticholinergic medication class, and dementia risk in 40 770 older adults. The third study, a longitudinal cohort study of 1028 Swedish older adults, examined the association between antihypertensive medications and incident dementia. The last study was a randomized, double‐blind, placebo‐controlled trial that investigated the effect of daily low‐dose aspirin (100 mg) for primary prevention on cardiovascular events and major hemorrhage in 19 144 community‐dwelling older adults. Collectively, this current article provides insight into the pertinent topics of medication use quality and safety in older adults and helps raise awareness about optimal prescribing in older adults.
