Improving the quality of medication use and medication safety are important priorities for healthcare providers who care for older adults. The objective of this article was to identify four exemplary articles with this focus in 2022. We selected high‐quality studies from an OVID search and hand searching of major high impact journals that advanced the field of research forward. The chosen articles cover domains related to deprescribing, medication safety, and optimizing medication use. The MedSafer Study, a cluster randomized clinical trial in Canada, evaluated whether patient specific deprescribing reports generated by electronic decision support software resulted in reduced adverse drug events in the 30 days post hospital discharge in older adults (domain: deprescribing). The second study, a retrospective cohort study using data from Premier Healthcare Database, examined in‐hospital adverse clinical events associated with perioperative gabapentin use among older adults undergoing major surgery (domain: medication safety). The third study used an open‐label parallel controlled trial in 39 Australian aged‐care facilities to examine the effectiveness of a pharmacist‐led intervention to reduce medication‐induced deterioration and adverse reactions (domain: optimizing medication use). Lastly, the fourth study engaged experts in a Delphi method process to develop a consensus list of clinically important prescribing cascades that adversely affect older persons' health to aid clinicians to identify, prevent, and manage prescribing cascades (domain: optimizing medication use). Collectively, this review succinctly highlights pertinent topics related to promoting safe use of medications and promotes awareness of optimizing older adults' medication regimens.

Background: We previously reported that interventions to optimize medication use reduced adverse drug reactions (ADRs) by 21% and serious ADRs by 36% in older adults. With new evidence, we sought to update the systematic review and meta-analysis. Method: We searched OVID, Cochrane Library, ClinicalTrials.gov and Google Scholar from 30 April 2017–30 April 2023. Included studies had to be randomized controlled trials of older adults (mean age ≥65 years) taking medications that examined the outcome of ADRs. Two authors independently reviewed all citations, extracted relevant data, and assessed studies for potential bias. The outcomes were any and serious ADRs. We performed subgroup analyses by intervention type and setting. Random-effects models were used to combine the results from multiple studies and create summary estimates. Results: Six studies are new to the update, resulting in 19 total studies (15,675 participants). Interventions were pharmacist-led (10 studies), other healthcare professional-led (5 studies), technology based (3 studies), and educational (1 study). The interventions were implemented in various clinical settings, including hospitals, outpatient clinics, long-term care facilities/rehabilitation wards, and community pharmacies. In the pooled analysis, the intervention group participants were 19% less likely to experience an ADR (odds ratio [OR] 0.81, 95% confidence interval [CI] 0.68–0.96) and 32% less likely to experience a serious ADR (OR 0.68, 95% CI 0.48–0.96). We also found that pharmacist-led interventions reduced the risk of any ADR by 35%, compared with 8% for other types of interventions. Conclusion: Interventions significantly and substantially reduced the risk of ADRs and serious ADRs in older adults. Future research should examine whether effectiveness of interventions vary across health care settings to identify those most likely to benefit. Implementation of successful interventions in health care systems may improve medication safety in older patients. [ABSTRACT FROM AUTHOR]

Background: Falls and fall-related injuries are of growing concern among older adults. Use of fall-risk-increasing drugs (FRIDs) is a potentially modifiable risk factor. This narrative review describes randomized controlled trials that focused on interventions to reduce FRID use and examined fall-related outcomes (e.g., falls, fractures, risk of injury) as the primary outcome. Methods: A comprehensive literature search was conducted to identify eligible studies. Two reviewers screened titles and abstracts and then performed a full-text review of relevant articles. Each study is summarized, and a discussion of strengths and limitations is provided. Results: 7 of 22 trials were included in this narrative review. Two studies used a computerized decision support intervention, three used a health professional-led (pharmacist or geriatrician) intervention, and two were direct medication withdrawal interventions. Three studies showed a reduction in fall-related outcomes (two identified fall injuries using claims data; one used an injury risk prediction score). Of these, only one reported FRID reduction. Of four studies that did not find a reduction in falls, one study reported a significant reduction in FRIDs, two found no reduction, and one did not report on this outcome. Most interventions consisted of a one-time FRID assessment, and most targeted either providers or patients (not both). Conclusion: Most interventions did not reduce FRID use or change fall-related outcomes. Future studies should test "multi-pronged" intervention strategies that simultaneously target both patients and their providers and include more than a single intervention interaction to reduce this modifiable fall risk factor.

Objectives To examine associations between angiotensin-converting enzyme ( ACE) inhibitor and statin medications and baseline and mean annual change in physical performance measures and muscle strength in older women. Design Prospective cohort study. Participants Participants from the Women's Health Initiative Clinical Trials aged 65 to 79 at baseline who had physical performance measures, self-report of health insurance, and no prior history of stroke or congestive heart failure were included (N = 5,777). Women were recruited between 1993 and 1998. Measurements Medication use was ascertained through a baseline inventory. Physical performance measures (timed 6-m walk, repeated chair stands in 15 seconds) and grip strength were assessed at baseline and follow-up Years 1, 3, and 6. Multivariable-adjusted linear repeated-measures models were adjusted for demographic and health characteristics. Results ACE inhibitor use was associated with lower mean grip strength at baseline (22.40 kg, 95% confidence interval ( CI) = 21.89-22.91 vs 23.18 kg, 95% CI 23.02-23.34; P = .005) and greater mean annual change in number of chair stands (−0.182, 95% CI −0.217 to −0.147 vs −0.145, 95% CI −0.156 to −0.133; P = .05) than nonuse. Statin use was not significantly associated with baseline measures or mean annual change for any outcome. A subgroup analysis suggested that statin use was associated with less mean annual change in chair stands ( P = .006) in the oldest women. Conclusion These results do not support an association between statin or ACE inhibitor use and slower decline in physical performance or muscle strength and thus do not support the use of these medications for preserving functional status in older adults.

Objectives To evaluate whether the use of angiotensin-converting enzyme ( ACE) inhibitors and statins is associated with a lower risk of incident mobility limitation in older community dwelling adults. Design Longitudinal cohort study. Setting Health, Aging and Body Composition (Health ABC) study. Participants Three thousand fifty-five participants who were well functioning at baseline (no mobility limitations). Measurements Summated standardized daily doses (low, medium, high) and duration of ACE inhibitor and statin use were computed. Mobility limitation (two consecutive self-reports of having any difficulty walking one-quarter of a mile or climbing 10 steps without resting) was assessed every 6 months after baseline. Multivariable Cox proportional hazards analyses were conducted, adjusting for demographics, health status, and health behaviors. Results At baseline, 15.2% used ACE inhibitors and 12.9% used statins; use of both was greater than 25% by Year 6. Over 6.5 years of follow-up, 49.8% had developed mobility limitation. In separate multivariable models, neither ACE inhibitor (multivariate hazard ratio ( HR) = 0.95, 95% confidence interval ( CI) = 0.82-1.09) nor statin use (multivariate HR = 1.02, 95% CI = 0.87-1.17) was associated with lower risk of mobility limitation. Similar findings were seen in analyses examining dose-response and duration-response relationships and a sensitivity analysis restricted to those with hypertension. Conclusion ACE inhibitors and statins widely prescribed to treat hypertension and hypercholesterolemia, respectively, do not lower risk of mobility limitation, an important indicator of quality of life.

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.

Objectives To examine the association between statin use and objectively assessed decline in gait speed in community-dwelling older adults. Design Longitudinal cohort study. Setting Health, Aging and Body Composition (Health ABC) Study. Participants Two thousand five participants aged 70-79 at baseline with medication and gait speed data at 1998-99, 1999-2000, 2001-02, and 2002-03. Measurements The independent variables were any statin use and their standardized daily doses (low, moderate, high) and lipophilicity. The primary outcome measure was decline in gait speed of 0.1 m/s or more in the following year of statin use. Multivariable generalized estimating equations were used, adjusting for demographic characteristics, health-related behaviors, health status, and access to health care. Results Statin use increased from 16.2% in 1998-99 to 25.6% in 2002-03. The overall proportions of those with decline in gait speed of 0.1 m/s or more increased from 22.2% in 1998 to 23.9% in 2003. Statin use was not associated with decline in gait speed of 0.1 m/s or more (adjusted odds ratio ( AOR) = 0.90, 95% confidence interval ( CI) = 0.77-1.06). Similar nonsignificant trends were also seen with the use of hydrophilic or lipophilic statins. Users of low-dose statins were found to have a 22% lower risk of decline in gait speed than nonusers ( AOR = 0.78, 95% CI = 0.61-0.99), which was mainly driven by the results from 1999-2000 follow-up. Conclusion These results suggest that statin use did not increase decline in gait speed in community-dwelling older adults. [ABSTRACT FROM AUTHOR]

Objective: To examine older adults' perceptions and identify barriers and enablers to initiating a conversation about stopping medication(s) with their healthcare provider.Methods: We conducted one focus group (n = 3) and in-depth, face-to-face, individual interviews (n = 6) using an interview guide. Older adults aged ≥65 years in a retirement community who were taking ≥5 medications were recruited. Focus groups and interviews were audio-recorded and transcribed verbatim. Both a deductive analysis, informed by the Theoretical Domains Framework, and an inductive analysis were conducted.Results: Five themes and fourteen sub-themes were identified. Theme 1, 'older adult-related barriers', discusses limited or varying self-efficacy, past unsuccessful deprescribing experiences and limited familiarity with medications/deprescribing. Theme 2, 'provider-related barriers', discusses trust, short office visits, lack of communication and multiple providers. Theme 3, 'environmental/social-related barriers', involves limited availability of resources and access to telehealth/internet. The remaining themes (Themes 4-5) identified enablers including strategies to promote older adults' self-efficacy and improved healthcare communication.Conclusion: Consumer-centric tools could improve older adults' self-efficacy to initiate deprescribing conversations.Practice Implications: Removing barriers and implementing enablers may empower older adults to initiate deprescribing conversations with providers to take fewer medications. Ultimately, this could be a catalyst for increased translation of deprescribing in practice. [ABSTRACT FROM AUTHOR]

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.

Objectives To examine the associations between depressive symptoms, antidepressant use, and duration of use with incident frailty 3 years later in nonfrail women aged 65 and older. Design Secondary analysis of the Women's Health Initiative Observational Study ( WHI- OS), a prospective cohort study. Setting WHI- OS was conducted in 40 U. S. clinical centers. Participants Women aged 65 to 79, not frail at baseline. Measurements Antidepressant use was assessed through medication container inspection at baseline. Four groups were created according to baseline use and Burnam depression screen (range 0-1, 0.06 cutoff): antidepressant nonusers without depressive symptoms (reference group), antidepressant nonusers with depressive symptoms, antidepressant users without depressive symptoms, and antidepressant users with depressive symptoms. Frailty components included slowness or weakness, exhaustion, low physical activity, and unintended weight loss, ascertained through self-report and physical measurements at baseline and Year 3. Results Of 27,652 women at baseline, 1,350 (4.9%) were antidepressant users and 1,794 (6.5%) were categorized as depressed. At Year 3, 4,125 (14.9%) were frail. All groups had a greater risk of incident frailty than the reference group. Odds ratios ( ORs) ranged from 1.73 (95% confidence interval ( CI) = 1.41-2.12) in antidepressant users who were not depressed to 3.63 in antidepressant users who were depressed (95% CI = 2.37-5.55). All durations of use were associated with incident frailty (<1 year OR = 1.95, 95% CI = 1.41-2.68; 1-3 years OR = 1.99, 95% CI = 1.45-2.74; >3 years OR = 1.60, 95% CI = 1.20-2.14). Conclusion In older adult women, depressive symptoms and antidepressant use were associated with frailty after 3 years of follow-up. [ABSTRACT FROM AUTHOR]

Objectives To determine the extent of concomitant use of cholinesterase inhibitor ( ChI) and anticholinergic ( ACh) medications and the clinical consequences of dual use in a population-based setting. Design Retrospective cohort study. Setting Group Health Cooperative and Kaiser Permanente Colorado. Participants Five thousand six hundred twenty-five adults aged 50 and older who began new use of a ChI between 2000 and 2007. Measurements Rates and characteristics of concomitant ChI and ACh use and the association between dual use and the outcomes of death and nursing home placement (claim from a nursing home with no prior claims used as a proxy). Results Thirty-seven percent of ChI users also received AChs. Eleven percent of ChI users were concomitantly using two or more moderate to potent AChs. Median duration of this concomitant use was approximately 4 months, but a substantial proportion (25%) continued to use both medication classes simultaneously for longer than 12 months. In 23% of ChI users, AChs were being used at the time ChI therapy was initiated. The majority of this ACh use (77%) was not stopped once ChIs were started. No association was observed between concomitant use and risk of death or nursing home placement. Conclusion These results should raise awareness about the prevalence and potential inappropriateness of concomitant use of ChIs and AChs and promote evaluations of practices intended to improve care standards.

Background impairments in neurotransmitter pathways put Parkinson's disease (PD) patients at risk for drug–disease interactions and adverse medication events. Objective to determine the prevalence and risk factors for potentially inappropriate medication (PIM) prescriptions, as defined by the 2015 Beers List, in PD. Methods cross-sectional analysis was conducted on 2014 Medicare beneficiaries with PD who had parts A, B and D coverage. The prevalence of PIM prescriptions for older adults was determined overall, and specifically for medications that can exacerbate motor symptoms or cognitive impairment in PD. Logistic regression models were constructed to determine the association between age, sex, race, geography and poverty with PIM prescriptions. Results the final sample included 458,086 beneficiaries. In 2014, 35.8% of beneficiaries with PD filled a prescription for at least one PIM for older adults. In total, 8.7% of beneficiaries received a PIM that could exacerbate motor symptoms and 29.0% received a PIM that could worsen cognitive impairment. After adjustment, in all models, beneficiaries who were younger, female, white, urban-dwelling and eligible for Medicaid benefits were more likely to receive a PIM. Conclusion PIM prescriptions are not uncommon in PD, particularly for medications that can exacerbate cognitive impairment. Future research will examine underlying drivers of sex and other disparities in PIM prescribing. Additional studies are needed to understand the impact of PIMs on disease symptoms, healthcare utilisation and patient outcomes. [ABSTRACT FROM AUTHOR]

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.

Objectives To evaluate the associations between anesthesia and dementia or Alzheimer's disease ( AD) risk using prospectively collected data. Design Cohort study. Participants Community-dwelling members of the Adult Changes in Thought cohort aged 65 and older and free of dementia at baseline (N = 3,988). Measurements Participants self-reported all prior surgical procedures with general or neuraxial (spinal or epidural) anesthesia at baseline and reported new procedures every 2 years. People undergoing high-risk surgery with general anesthesia, other surgery with general anesthesia, and other surgery with neuraxial anesthesia exposures were compared with those with no surgery and no anesthesia. Cox proportional hazards models were used to estimate hazard ratios ( HRs) and 95% confidence intervals ( CIs) for dementia and AD associated with time-varying lifetime and recent (past 5 years) anesthesia exposures. Results At baseline, 254 (6%) people reported never having anesthesia; 248 (6%) had had one or more high-risk surgeries with general anesthesia, 3,363 (84%) had had one or more other surgeries with general anesthesia, and 123 (3%) had had one or more surgeries with neuraxial anesthesia. High-risk surgery with general anesthesia was not associated with greater risk of dementia (HR = 0.86, 95% CI = 0.58-1.28) or AD (HR = 0.95, 95% CI = 0.61-1.49) than no history of anesthesia. People with any history of other surgery with general anesthesia had a lower risk of dementia (HR = 0.63, 95% CI = 0.46-0.85) and AD (HR = 0.65, 95% CI = 0.46-0.93) than people with no history of anesthesia. There was no association between recent anesthesia exposure and dementia or AD. Conclusion Anesthesia exposure was not associated with of dementia or AD in older adults. [ABSTRACT FROM AUTHOR]
