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.

ObjectivesTo compare the ability of the commonly used Women's Health Initiative (WHI) and Cardiovascular Health Study (CHS) frailty phenotypes to predict falls, hip fracture, and death in WHI Clinical Trial participants aged 65 and older.DesignLongitudinal cohort study.SettingWHI Clinical Trial.ParticipantsParticipants with data for WHI and CHS frailty phenotypes (N = 3,558).MeasurementsFrailty was operationally defined in the CHS as the presence of three or more of weight loss, poor energy, weakness, slowness, and low physical activity. WHI operationalized frailty similarly but with the RAND-36 physical function scale substituted for slowness and weakness (RAND-36 physical function scale score 78 = 0 points). Frailty was defined as a summary score of 3 or greater, prefrailty as a score of 2 or 1, and nonfrailty as a score of 0. Outcomes were modeled using Cox regression. Harrell C-statistics were compared for models containing alternative instruments.ResultsApproximately 5% of participants were frail based on the CHS or WHI phenotype. The WHI frailty phenotype was associated with higher rates of falls (hazard ratio (HR) = 1.48, P = .003), hip fracture (HR = 1.87, P = .04), and death (HR = 2.32, P < .001). Comparable HRs in CHS-phenotype frail women were 1.32 (P = .04), 1.08 (P = .83), and 1.91 (P < .001), respectively. Harrell C-statistics revealed marked but insignificant differences in predicting abilities between CHS and WHI phenotype models (P > .50 for all).ConclusionThe WHI phenotype, which does not require direct measurements of physical performance, might offer a practical advantage for epidemiological and clinical needs.

ObjectivesTo examine the association between statin use and objectively assessed decline in gait speed in community-dwelling older adults.DesignLongitudinal cohort study.SettingHealth, Aging and Body Composition (Health ABC) Study.ParticipantsTwo thousand five participants aged 70-79 at baseline with medication and gait speed data at 1998-99, 1999-2000, 2001-02, and 2002-03.MeasurementsThe 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.ResultsStatin 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.ConclusionThese results suggest that statin use did not increase decline in gait speed in community-dwelling older adults.

ObjectivesTo 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.DesignProspective cohort study.ParticipantsParticipants 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.MeasurementsMedication 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.ResultsACE 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.ConclusionThese 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.

ObjectivesTo 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.DesignSecondary analysis of the Women's Health Initiative Observational Study (WHI-OS), a prospective cohort study.SettingWHI-OS was conducted in 40 U.S. clinical centers.ParticipantsWomen aged 65 to 79, not frail at baseline.MeasurementsAntidepressant 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.ResultsOf 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 (3 years OR = 1.60, 95% CI = 1.20-2.14).ConclusionIn older adult women, depressive symptoms and antidepressant use were associated with frailty after 3 years of follow-up.

ObjectivesTo examine the associations between current use, duration, and potency of angiotensin-converting enzyme (ACE) inhibitors and incident frailty in women aged 65 and older who were not frail at baseline.DesignData were from the Women's Health Initiative Observational Study (WHI-OS), a prospective study conducted at 40 U.S. clinical centers.ParticipantsWomen aged 65 to 79 at baseline who were not frail (N=27,378).MeasurementsCurrent ACE inhibitor use was ascertained through direct inspection of medicine containers at baseline. Components of frailty were self-reported low physical function or impaired walking, exhaustion, low physical activity, and unintended weight. Frailty was ascertained through self-reported and physical measurements data at baseline and 3-year clinic contacts.ResultsBy the 3-year follow-up, 3,950 (14.4%) women had developed frailty. Current ACE inhibitor use had no association with incident frailty (multivariate adjusted odds ratio=0.96, 95% confidence interval=0.82-1.13). Duration and potency of ACE inhibitor use were also not significantly associated with incident frailty. A similar pattern of results was observed when incident cardiovascular disease events were studied as a separate outcome or when the sample was restricted to subjects with hypertension.ConclusionOverall, incidence of frailty was similar in current ACE inhibitor users and nonusers.

ObjectivesTo determine whether benzodiazepine use is associated with incident disability in mobility and activities of daily living (ADLs) in older individuals.DesignA prospective cohort study.SettingFour sites of the Established Populations for Epidemiologic Studies of the Elderly.ParticipantsThis study included 9,093 subjects (aged > or =65) who were not disabled in mobility or ADLs at baseline.MeasurementsMobility disability was defined as inability to walk half a mile or climb one flight of stairs. ADL disability was defined as inability to perform one or more basic ADLs (bathing, eating, dressing, transferring from a bed to a chair, using the toilet, or walking across a small room). Trained interviewers assessed outcomes annually.ResultsAt baseline, 5.5% of subjects reported benzodiazepine use. In multivariable models, benzodiazepine users were 1.23 times as likely as nonusers (95% confidence interval (CI) = 1.09-1.39) to develop mobility disability and 1.28 times as likely (95% CI = 1.09-1.52) to develop ADL disability. Risk for incident mobility was increased with short- (hazard ratio (HR) = 1.27, 95% CI = 1.08-1.50) and long-acting benzodiazepines (HR = 1.20, 95% CI = 1.03-1.39) and no use. Risk for ADL disability was greater with short- (HR = 1.58, 95% CI = 1.25-2.01) but not long-acting (HR = 1.11, 95% CI = 0.89-1.39) agents than for no use.ConclusionOlder adults taking benzodiazepines have a greater risk for incident mobility and ADL disability. Use of short-acting agents does not appear to confer any safety benefits over long-acting agents.

ObjectivesTo define frailty using simple indicators; to identify risk factors for frailty as targets for prevention; and to investigate the predictive validity of this frailty classification for death, hospitalization, hip fracture, and activity of daily living (ADL) disability.DesignProspective study, the Women's Health Initiative Observational Study.SettingForty U.S. clinical centers.ParticipantsForty thousand six hundred fifty-seven women aged 65 to 79 at baseline.MeasurementsComponents of frailty included self-reported muscle weakness/impaired walking, exhaustion, low physical activity, and unintended weight loss between baseline and 3 years of follow-up. Death, hip fractures, ADL disability, and hospitalizations were ascertained during an average of 5.9 years of follow-up.ResultsBaseline frailty was classified in 16.3% of participants, and incident frailty at 3-years was 14.8%. Older age, chronic conditions, smoking, and depressive symptom score were positively associated with incident frailty, whereas income, moderate alcohol use, living alone, and self-reported health were inversely associated. Being underweight, overweight, or obese all carried significantly higher risk of frailty than normal weight. Baseline frailty independently predicted risk of death (hazard ratio (HR)=1.71, 95% confidence interval (CI)=1.48-1.97), hip fracture (HR=1.57, 95% CI=1.11-2.20), ADL disability (odds ratio (OR)=3.15, 95% CI=2.47-4.02), and hospitalizations (OR=1.95, 95% CI=1.72-2.22) after adjustment for demographic characteristics, health behaviors, disability, and comorbid conditions.ConclusionThese results support the robustness of the concept of frailty as a geriatric syndrome that predicts several poor outcomes in older women. Underweight, obesity, smoking, and depressive symptoms are strongly associated with the development of frailty and represent important targets for prevention.

OBJECTIVES:To determine whether benzodiazepine use in older women increased the risk of decline in physical function. DESIGN:A four-year prospective cohort study. SETTING:The communities of Iowa and Washington counties, Iowa. PARTICIPANTS:Eight hundred eighty-five women aged 70 and older who had completed physical performance tests in 1988 and 1992. MEASUREMENTS:Benzodiazepine use was determined during in-home interviews and classified by dose, duration, indication for use, and half-life. Physical performance tests included an assessment of standing balance, walking speed (8-foot distance), and repeated chair raises. RESULTS:Ninety (10.2%) reported benzodiazepine use at baseline. After adjustment for baseline physical performance score and potential confounders, benzodiazepine use was associated with a greater decline in physical performance over 4 years than nonuse (beta=-1.16; standard error (SE)=0.25; Por=3 years) was related to decline (beta=-1.65; SE=0.34; Por=3 years). These findings highlight the importance of using benzodiazepines at the lowest effective dose for a limited duration in older women.

ObjectivesThis study examined the association between benzodiazepine use and incident disability with an emphasis on elucidating whether the underlying health conditions that result in benzodiazepine use (confounding factors) or intrinsic adverse effects of benzodiazepine use were responsible for functional decline.DesignCohort study with follow-up of 4 to 5 years.SettingA health maintenance organization (HMO) in western Washington.ParticipantsIndividuals aged 65 and older from a random sample of HMO enrollees who participated in a health promotion intervention trial (n = 1,519).MeasurementsBenzodiazepine use was ascertained from computerized pharmacy records. Self-reported functional status was assessed using a six-item physical function scale ranging from vigorous activity to self-care activities of daily living (ADLs). Two outcomes were examined: decline in overall physical function and limitations in self-care ADLs. Multivariate models were examined that included demographic characteristics, health status, and health behaviors that were likely to be confounders. Several analyses were conducted to examine whether benzodiazepine use or confounding factors were responsible for functional decline.ResultsBenzodiazepine use was significantly associated with incident loss of physical function (hazard ratio (HR) = 1.51, 95% confidence interval (CI) = 1.02-2.24) in the fully adjusted model. Although use of benzodiazepines was associated with limitations in ADLs, it was not significant when adjusting for other factors (HR = 1.71, 95% CI = 0.87-3.34). Several of our findings suggest that the health conditions leading to benzodiazepine use may partly or fully explain these associations: (1) use of anxiolytic benzodiazepines (HR = 1.95, 95% CI = 1.24-3.07), but not hypnotic agents (HR = 1.21, 95% CI = 0.73-2.00), was associated with functional decline; (2) adjustment for health status variables minimized these associations; and (3) there was little evidence of dose response.ConclusionsA modestly increased risk for decline in physical function was associated with benzodiazepine use, especially of anxiolytic agents. The health conditions that result in benzodiazepine use may be more important in the pathogenesis of disability than benzodiazepine use itself. Although there are many reasons for avoiding benzodiazepines in older adults, it is still unclear whether use contributes independently to functional decline.

Background: While many studies have assessed and measured patient attitudes toward deprescribing, less quantitative research has addressed the provider perspective. We thus sought to describe provider knowledge, beliefs, and self‐efficacy to deprescribe, with a focus on opioids and sedative‐hypnotics. Methods: An electronic anonymous survey was distributed to primary care providers at Kaiser Permanente Washington. Two reminder emails were sent. The survey included 10 questions on general deprescribing, and six questions each specific to opioid and sedative‐hypnotic deprescribing. Knowledge questions used a multiple‐choice response option format. Questions addressing beliefs and self‐efficacy (i.e., confidence) used a 0–10 Likert scale. Scales were dichotomized at ≥7 to define agreement (belief questions) or confidence (self‐efficacy questions). We calculated descriptive statistics to summarize the responses. Results: Of 370 eligible primary care providers, 95 (26%) completed the survey. For general deprescribing questions, a majority believed that lack of patient willingness, withdrawal symptoms and fear of symptom return, and time constraints impeded deprescribing. Approximately half chose the correct answers about opioid deprescribing, 21% were confident that they could alleviate patient concerns about opioid tapering, and 32% were confident managing chronic non‐cancer pain without opioids. For sedative‐hypnotics, 64%–87% of respondents correctly answered questions about risks and the relative effectiveness of alternatives, but only one‐third correctly answered a question about sedative‐hypnotic tapering. Roughly half were confident in their ability to successfully engage patients in sedative deprescribing conversations and select alternatives. Only 54% and 34% were confident in writing a tapering protocol for opioids and sedative‐hypnotics, respectively. Conclusion: Results suggest that raising provider awareness of patient willingness to deprescribe, addressing knowledge gaps, and increasing self‐efficacy for deprescribing are important targets for improving deprescribing. Support for writing tapering protocols and prescribing evidence‐based drug and non‐drug alternatives may be important to improve care. [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.
