RESUMO
BACKGROUND: One's experience with dementia may affect their perceptions about dementia preventability, which in turn could influence preventive health behaviors. We aimed to examine how having a family history of dementia and caregiving experience are associated with perceptions about and self-efficacy for dementia preventability. METHODS: Cross-sectional, self-administered survey. Participants reported whether they have had a family member with dementia and, among those who reported having a family member with dementia, whether they served as a caregiver. Outcomes were perceptions about the likelihood of dementia preventability, self-efficacy for dementia prevention, and benefits of specific dementia prevention strategies. Associations were assessed via partial proportional odds model for ordinal outcome variables and logistic regression for binary outcome variables. RESULTS: Of 1,575 respondents, 71% had a family member with dementia, of which 42% served as a caregiver. People with a family member with dementia were less likely to believe that dementia is preventable (aOR = 0.75, 95% CI: 0.58, 0.96) and had lower self-efficacy for dementia prevention (aOR = 0.71, 95% CI: 0.56, 0.90). The subgroup analysis among those with caregiving experience was consistent with the primary findings, showing less belief in the likelihood of dementia preventability (aOR = 0.69, 95% CI: 0.46, 1.03) and self-efficacy (aOR = 0.75, 95% CI: 0.56, 1.00). CONCLUSION: Having a family member with dementia is associated with unfavorable perceptions about dementia preventability. Incorporating family history of dementia into communication efforts about dementia risk reduction may help address potential barriers to preventive health behaviors.

BACKGROUND: Medication management requires complex cognitive functioning, and therefore, difficulty taking medications might be an early sign of cognitive impairment and could be a risk factor for Alzheimer's disease and related dementias (ADRD). Accordingly, people with difficulty taking medications may benefit from more detailed cognitive screening, potentially aiding in the diagnosis of ADRD, which is underdiagnosed. We are unaware of evidence on medication management difficulties that precede a real-world ADRD diagnosis in the USA. OBJECTIVE: Examine the association between difficulty taking medications and subsequent real-world ADRD diagnoses. DESIGN: Case-control study, using Health and Retirement Study (HRS) survey data linked to Medicare claims. PARTICIPANTS: A total of 1461 HRS respondents with an ADRD diagnosis observed from 1993 to 2012 (cases), matched by year of birth, wave of HRS entry, and sex to 3771 controls with no ADRD diagnosis. MAIN MEASURES: We examined the association between diagnosis of ADRD and self-reported difficulty taking medications in the preceding years (1-2 and 3-4 years prior to case definition). Control individuals were assigned the index date from their matched case. Conditional logistic regressions adjusted for age, sex, race, education, and comorbidities. KEY RESULTS: Compared with matched controls, cases had higher prevalence of difficulty taking medications 1-2 years prior to diagnosis (11.0% versus 2.3%), and 3-4 years prior to diagnosis (5.8% versus 2.3%). Adjusted analyses showed that compared with individuals without ADRD, those with an ADRD diagnosis had more than four times higher odds of difficulty taking medications 1-2 years prior (OR = 4.56 (CI 3.30-6.31)), and more than two times higher odds of difficulty taking medications 3-4 years prior (OR = 2.41 (CI 1.61-3.59)). CONCLUSIONS: Odds of medication difficulty 1-2 years prior were more than four times greater for individuals with ADRD diagnoses compared with those without ADRD. Medication management difficulties may prompt further cognitive screening, potentially aiding in earlier recognition of ADRD.

OBJECTIVE: To examine the national prevalence of pharmacological treatment of affective disorders in older adults with Parkinson's disease (PD), and determine the prevalence and risk factors for receipt of an American Geriatrics Society Beers Criteria® defined potentially inappropriate medication (PIM) for affective disorder treatment. DESIGN: Cross-sectional analysis of 2014 Medicare data. SETTING: Research Identifiable File data from the Centers for Medicare and Medicaid Services. PARTICIPANTS: Individuals ≥65 years of age with PD whose inpatient, outpatient, and prescription care is administered through the U.S. Medicare Program. MEASUREMENTS: The 2014 prevalence of affective (i.e., depressive and anxiety) disorders was calculated. We assessed prescription fills for affective disorder treatment and classified prescriptions according to PIM status. Patient and clinician factors associated with PIM prescriptions were determined. RESULTS: Of 84,323 beneficiaries with PD, 15.1% had prevalent depression only, 7.5% had anxiety only, and 8.5% had comorbid depression and anxiety. Among those with depression only, 80.7% were treated in 2014 (12.8% of treated received at least one PIM). The annual treatment prevalence was 62.9% (75.9% PIM) and 93.1% (63.9% PIM) in the anxiety only and comorbid group, respectively. In most groups, PIM use was less likely among men and those with dementia; geriatricians were less likely to prescribe PIMs. CONCLUSION: Treatment of affective disorders in persons diagnosed with PD is high. PIM use is also common, particularly in persons with anxiety. Future research will quantify the potential effects of these PIMs on clinical and patient outcomes.

PURPOSE: Bladder antimuscarinic (BAM) drug use is associated with increased risk of Alzheimer's disease and related dementias (ADRD). It is hypothesized that BAMs with non-selective receptor binding may increase ADRD risk more than M3-selective BAMs. This study compared ADRD risk for users of non-selective and M3-selective BAMs and examines ADRD risk associated with overall BAM use. METHODS: Retrospective cohort study of Medicare claims for 71 688 individuals who used BAM drugs during 2007-2009 without an ADRD diagnosis. We compared ADRD incidence (2011-2016) between non-selective BAM users (fesoterodine, flavoxate, oxybutynin, tolterodine, trospium) and M3-selective BAM users (darifenacin, solifenacin). Logistic regressions compared individuals using target drugs in the same category of total standardized daily doses (TSDD) as a standardized measure of drug exposure, and adjusted for age, sex, race/ethnicity, healthcare utilization, other medication use, socioeconomic status, and comorbidities. Secondary analyses compared ADRD risk associated with different doses of BAMs overall. RESULTS: Non-selective BAM use (compared to M3-selective) was not significantly associated with ADRD incidence. Odds ratios for non-selective use were 0.97 (CI: 0.89-1.04) for 1-364 TSDD, 0.94 (CI: 0.83-1.06) for 365-729, 1.00 (CI: 0.87-1.16) for 730-1094, and 1.03 (CI: 0.88-1.20) for >1094. Higher TSDD of BAMs overall (combining both non-selective and M3-selective BAMs), when compared to 1-364 TSDD, were associated with increased ADRD incidence (OR = 1.05 (CI: 0.99-1.10) for 365-729, OR = 1.11 (CI: 1.05-1.17) for 730-1094, and OR = 1.10 (CI: 1.04-1.15) for >1094). CONCLUSIONS: Non-selective and M3-selective BAM users had similar odds of ADRD incidence, and BAM use overall was significantly associated with ADRD incidence.

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.

BACKGROUND: Detecting patients with undiagnosed dementia is an important clinical challenge. Changes in medication adherence might represent an early sign of cognitive impairment. We sought to examine antihypertensive and statin adherence trajectories in community-dwelling older adults, comparing people who went on to develop dementia to those who did not. METHODS: We analyzed data from Adult Changes in Thought (ACT), a population-based cohort study embedded within an integrated healthcare delivery system. Analyses included 4368 participants aged ≥65 years who had at least one follow-up visit. Research-quality dementia diagnoses were used to identify cases. We selected non-dementia control visits matched on age, sex, and study cohort that occurred at similar ACT follow-up time as the case's dementia onset; we treated this as the index date. Participants were included if they were prevalent users of either a statin or antihypertensive medication on the first day of follow up - 3 years prior to the index date. Using prescription fill dates and days supply, we calculated daily binary medication availability measures for each participant ('days covered') over 3 years leading up to the index date. We used group-based trajectory models to identify patterns of antihypertensive and statin adherence, and used conditional logistic regression to examine associations between adherence trajectories and dementia. RESULTS: Four trajectories were identified for antihypertensive users (292 cases, 3890 control visits), including near perfect (n = 1877, 36.6% cases, 45.5% controls), high (n = 1840, 43.2% cases, 44.1% controls), moderate (n = 365, 18.5% cases, 8.0% controls) and early poor adherence (n = 100, 1.7% cases, 2.4% controls). Odds of dementia was 3 times greater for those with moderate antihypertensive adherence compared to those with near perfect adherence (adjusted OR 3.0, 95% CI 2.0, 4.3). Four trajectories were identified for statin users (148 cases, 1131 control visits), including high (n = 1004, 75.0% cases, 79.0% controls), moderate (n = 192, 19.6% cases, 14.4% controls), early poor (n = 43, 2.0% cases, 3.5% controls), and delayed poor adherence (n = 40, 3.4% cases, 3.1% controls). No association was detected between statin adherence trajectories and dementia. CONCLUSIONS: Patterns of medication adherence may be useful to identify a subset of people at higher likelihood of developing dementia.

OBJECTIVES: To describe the prevalence of, types of, and characteristics associated with self-reporting multiple (≥ 2) barriers to medication use in older women using long-term cardiovascular and oral hypoglycemic medications. METHODS: This cross-sectional study set at the Women's Health Initiative during 2005-2010 included women who were using any chronic medication from 3 target classes (i.e., antilipemics, antihypertensives, oral hypoglycemics) for at least 1 month and who had answered questions about barriers to medication use at year 4 (2009) of the study period (N = 59,054). Measurements included common self-reported barriers to medication use, and sociodemographic, health characteristic, medication use, and access to care variables were evaluated. Multivariable logistic regression models were used to examine associations between participant characteristics and barriers to medication use. RESULTS: Among the participants, 47,846 (81%) reported no barriers, 7105 (12%) reported 1 barrier, and 4103 (6.9%) reported 2 or more barriers to medication use. The most common barriers reported were having concerns about adverse effects, not liking to take medications, and medications costing too much. Several characteristics were found to be associated with reporting 2 or more barriers in multivariable modeling, including demographic (e.g., lower age, black race, Hispanic ethnicity) and health or medication (e.g., lower quality of life, lower physical function, higher number of concurrent medications) characteristics. CONCLUSION: Among older women using chronic cardiovascular and oral hypoglycemic medications, approximately 20% reported at least 1 barrier to medication use, with 7% of women reporting multiple barriers. Pharmacists should prioritize identifying barriers to medication use in older women using chronic medications to improve patient care.

In previous studies, we found modestly decreased and increased risks of second breast cancer events with the use of statins and antibiotics, respectively, after adjustment for surveillance mammography. We evaluated detection bias by comparing receipt of surveillance mammography among users of these 2 disparate classes of medication. Adult women diagnosed with early-stage breast cancer during 1990-2008 (n = 3,965) while enrolled in an integrated health-care plan (Group Health Cooperative; Washington State) were followed for up to 10 years in the Commonly Used Medications and Breast Cancer Outcomes (COMBO) Study. Categories of antibiotic use included infrequent (1-3 dispensings/12 months) and frequent (≥4 dispensings/12 months) use, and categories of statin use included less adherent (1 dispensing/6 months) and adherent (≥2 dispensings/6 months). We examined associations between medication use and surveillance mammography using multivariable generalized estimating equations and evaluated the impact of adjusting for surveillance within Cox proportional hazard models. Frequent antibiotic users were less likely to receive surveillance mammography (odds ratio (OR) = 0.90, 95% confidence interval (CI): 0.82, 0.99) than were nonusers; no association was found among infrequent users (OR = 0.96, 95% CI: 0.90, 1.03). Adherent statin use was associated with more surveillance compared with nonuse (OR = 1.11, 95% CI: 1.01, 1.25), but less adherent statin use was not (OR = 1.03, 95% CI: 0.81, 1.31). No difference in associations between medications of interest and second breast cancer events was observed when surveillance was removed from otherwise adjusted models. The influence of detection bias by medication use warrants further exploration.

BACKGROUND: Mechanisms linking cognitive and physical functioning in older adults are unclear. We sought to determine whether brain pathological changes relate to the level or rate of physical performance decline. METHODS: This study analyzed data from 305 participants in the autopsy subcohort of the prospective Adult Changes in Thought (ACT) study. Participants were aged 65+ and free of dementia at enrollment. Physical performance was measured at baseline and every two years using the Short Physical Performance Battery (SPPB). Data from 3174 ACT participants with ≥2 SPPB measurements were used to estimate two physical function measures: 1) rate of SPPB decline defined by intercept and slope; and 2) estimated SPPB 5 years prior to death. Neuropathology findings at autopsy included neurofibrillary tangles (Braak stage), neuritic plaques (CERAD level), presence of amyloid angiopathy, microinfarcts, cystic infarcts, and Lewy bodies. Associations (adjusted for sex, age, body mass index and education) between dichotomized neuropathologic outcomes and SPPB measures were estimated using modified Poisson regression with inverse probability weights (IPW) estimated via Generalized Estimating Equations (GEE). Relative risks for the 20th, 40th, and 60th percentiles (lowest levels and highest rates of decline) relative to the 80th percentile (highest level and lowest rate of decline) were calculated. RESULTS: Decedents with the least vs. most SPPB decline (slope > 75th vs. < 25th percentiles) had higher SPPB scores, and were more likely to be male, older, have higher education, and exercise regularly at baseline. No significant associations were observed between neuropathology findings and rate of SPPB decline. Lower predicted SPPB scores 5 years prior to death were associated with higher risk of microinfarcts (RR = 3.08, 95% confidence interval (CI) 0.93-1.07 for the 20th vs. 80th percentiles of SPPB) and significantly higher risk of cystic infarcts (RR = 2.72, 95% CI 1.45-5.57 for 20th vs. 80th percentiles of SPPB). CONCLUSION: Cystic infarcts and microinfarcts, but not neuropathology findings of Alzheimer's disease, were related to physical performance levels five years before death. No pathology findings were associated with rates of physical performance decline. Physical function levels in the years prior to death may be affected by vascular brain pathologies.

While data are accumulating on the association between neuropsychological performance and real-world endpoints, less is known about the association with medical self-management skills. The self-management of type 1 diabetes (T1D) is often complex, and mismanagement can result in hypoglycaemia and hyperglycaemia and associated morbidity and mortality. The T1D Exchange conducted a case-control study evaluating factors associated with severe hypoglycaemia in older adults (≥ 60 years old) with longstanding T1D (≥ 20 years). A battery of neuropsychological and functional assessments was administered, including measures of diabetes-specific self-management skill (diabetes numeracy) and instrumental activities of daily living (IADL). After adjusting for confounding variables, diabetes numeracy was related to memory and complex speeded attention; while IADL were associated with simple processing speed, executive functioning, complex speeded attention and dominant hand dexterity. The severity of overall cognitive deficit was uniquely associated with both diabetes numeracy and IADL, when controlling for age, education, frailty and depression. This study demonstrates that the cognitive deficits in older adults with T1D have functional implications for both diabetes management and IADL. Further research is needed to determine specific interventions to maximise diabetes self-management in older adults with declining cognition.

BACKGROUND: Few studies have compared the risk of recurrent falls across various antidepressant agents-using detailed dosage and duration data-among community-dwelling older adults, including those who have a history of a fall/fracture. OBJECTIVE: To examine the association of antidepressant use with recurrent falls, including among those with a history of falls/fractures, in community-dwelling elders. METHODS: This was a longitudinal analysis of 2948 participants with data collected via interview at year 1 from the Health, Aging and Body Composition study and followed through year 7 (1997-2004). Any antidepressant medication use was self-reported at years 1, 2, 3, 5, and 6 and further categorized as (1) selective serotonin reuptake inhibitors (SSRIs), (2) tricyclic antidepressants, and (3) others. Dosage and duration were examined. The outcome was recurrent falls (≥2) in the ensuing 12-month period following each medication data collection. RESULTS: Using multivariable generalized estimating equations models, we observed a 48% greater likelihood of recurrent falls in antidepressant users compared with nonusers (adjusted odds ratio [AOR] = 1.48; 95% CI = 1.12-1.96). Increased likelihood was also found among those taking SSRIs (AOR = 1.62; 95% CI = 1.15-2.28), with short duration of use (AOR = 1.47; 95% CI = 1.04-2.00), and taking moderate dosages (AOR = 1.59; 95% CI = 1.15-2.18), all compared with no antidepressant use. Stratified analysis revealed an increased likelihood among users with a baseline history of falls/fractures compared with nonusers (AOR = 1.83; 95% CI = 1.28-2.63). CONCLUSION: Antidepressant use overall, SSRI use, short duration of use, and moderate dosage were associated with recurrent falls. Those with a history of falls/fractures also had an increased likelihood of recurrent falls.

BACKGROUND: Results from studies assessing the association between anticholinergic use and falls are mixed, and prior studies are limited in their ability to control for important potential confounders. Thus, we sought to examine the association between anticholinergic medication use, including over-the-counter medications, and recurrent falls in community-dwelling older women. METHODS: We analyzed data from a prospective cohort study of women aged 65 to 79 years from the Women's Health Initiative Observational Study and Clinical Trials. Women were recruited between 1993 and 1998, and analyses included 61,451 women with complete information. Medications with moderate or strong anticholinergic effects were ascertained directly from drug containers during face-to-face interviews. The main outcome measure was recurrent falls (≥2 falls in previous year), which was determined from self-report within 1.5 years subsequent to the medication assessment. RESULTS: At baseline, 11.3 % were using an anticholinergic medication, of which antihistamines (commonly available over-the-counter) were the most common medication class (received by 45.2 % of individuals on anticholinergic medication). Using multivariable GEE models and controlling for potential confounders, the adjusted odds ratio for anticholinergic medication use was 1.51 (95 % CI, 1.43-1.60) for recurrent falls. Participants using multiple anticholinergic medications had a 100 % increase in likelihood of recurrent falls (adjusted odds ratio 2.00, 95 % CI 1.73-2.32). Results were robust to sensitivity analysis. CONCLUSIONS: Anticholinergic medication use was associated with increased risk for recurrent falls. Our findings reinforce judicious use of anticholinergic medications in older women. Public health efforts should emphasize educating older women regarding the risk of using over-the-counter anticholinergics, such as first-generation antihistamines.

BACKGROUND: Although it is generally accepted that anticholinergic use may lead to a fall, results from studies assessing the association between anticholinergic use and falls are mixed. In addition, direct evidence of an association between use of anticholinergic medications and recurrent falls among community-dwelling elders is not available. OBJECTIVE: To assess the association between anticholinergic use across multiple anticholinergic subclasses, including over-the-counter medications, and recurrent falls. METHODS: This was a longitudinal analysis of 2948 participants, with data collected via interview at year 1 from the Health, Aging and Body Composition study and followed through year 7 (1997-2004). Self-reported use of anticholinergic medication was identified at years 1, 2, 3, 5, and 6 as defined by the list from the 2015 American Geriatrics Society Beers Criteria. Dosage and duration were also examined. The main outcome was recurrent falls (≥2) in an ensuing 12-month period from each medication data collection. RESULTS: Using multivariable generalized estimating equation models, controlling for demographic, health status/behaviors, and access-to-care factors, a 34% increase in likelihood of recurrent falls in anticholinergic users (adjusted odds ratio = 1.34; 95% CI = 0.93-1.93) was observed, but the results were not statistically significant; similar results were found with higher doses and longer duration of use. CONCLUSION: Increased point estimates suggest an association of anticholinergic use with recurrent falls, but the associations did not reach statistical significance. Future studies are needed for more definitive evidence and to examine other measures of anticholinergic burden and associations with more intermediate adverse effects such as cognitive function.

Clinical practice guidelines recommend yearly surveillance mammography for breast cancer survivors, yet many women do not receive this service. The objective of this study was to evaluate factors related to long-term surveillance mammography adherence among breast cancer survivors. We conducted a retrospective cohort study among women ≥ 18 years, diagnosed with incident stage I or II breast cancer between 1990 and 2008. We used medical record and administrative health plan data to ascertain covariates and receipt of surveillance mammography for up to 10 years after completing breast cancer treatment. Surveillance included post-diagnosis screening exams among asymptomatic women. We used multivariable repeated measures generalized estimating equation regression models to estimate odds ratios and robust 95 % confidence intervals to examine factors related to the annual receipt of surveillance mammography. The analysis included 3,965 women followed for a median of six surveillance years; 79 % received surveillance mammograms in year 1 but decreased to 63 % in year 10. In multivariable analyses, women, who were < 40 years or 80+ years of age (compared to 50-59 years), current smokers, had greater comorbidity, were diagnosed more recently, had stage II cancer, or were treated with mastectomy or breast conserving surgery without radiation, were less likely than other women to receive surveillance mammography. Women with outpatient visits during the year to primary care providers, oncologists, or both were more likely to undergo surveillance. In this large cohort study of women diagnosed with early-stage invasive breast cancer, we found that important subgroups of women are at high risk for non-adherence to surveillance recommendations, even among younger breast cancer survivors. Efforts should be undertaken to actively engage breast cancer survivors in managing long-term surveillance care.

Importance: High-risk medications that contribute to adverse health outcomes are frequently prescribed to older adults. Deprescribing interventions reduce their use, but studies are often not designed to examine effects on patient-relevant health outcomes. Objective: To test the effect of a health system-embedded deprescribing intervention targeting older adults and their primary care clinicians for reducing the use of central nervous system-active drugs and preventing medically treated falls. Design, Setting, and Participants: In this cluster randomized, parallel-group, clinical trial, 18 primary care practices from an integrated health care delivery system in Washington state were recruited from April 1, 2021, to June 16, 2022, to participate, along with their eligible patients. Randomization occurred at the clinic level. Patients were community-dwelling adults aged 60 years or older, prescribed at least 1 medication from any of 5 targeted medication classes (opioids, sedative-hypnotics, skeletal muscle relaxants, tricyclic antidepressants, and first-generation antihistamines) for at least 3 consecutive months. Intervention: Patient education and clinician decision support. Control arm participants received usual care. Main Outcomes and Measures: The primary outcome was medically treated falls. Secondary outcomes included medication discontinuation, sustained medication discontinuation, and dose reduction of any and each target medication. Serious adverse drug withdrawal events involving opioids or sedative-hypnotics were the main safety outcome. Analyses were conducted using intent-to-treat analysis. Results: Among 2367 patient participants (mean [SD] age, 70.6 [7.6] years; 1488 women [63%]), the adjusted cumulative incidence rate of a first medically treated fall at 18 months was 0.33 (95% CI, 0.29-0.37) in the intervention group and 0.30 (95% CI, 0.27-0.34) in the usual care group (estimated adjusted hazard ratio, 1.11 (95% CI, 0.94-1.31) (P = .11). There were significant differences favoring the intervention group in discontinuation, sustained discontinuation, and dose reduction of tricyclic antidepressants at 6 months (discontinuation adjusted rate: intervention group, 0.23 [95% CI, 0.18-0.28] vs usual care group, 0.13 [95% CI, 0.09-0.17]; adjusted relative risk, 1.79 [95% CI, 1.29-2.50]; P = .001) and secondary time points (9, 12, and 15 months). Conclusions and Relevance: In this randomized clinical trial of a health system-embedded deprescribing intervention targeting community-dwelling older adults prescribed central nervous system-active medications and their primary care clinicians, the intervention was no more effective than usual care in reducing medically treated falls. For health systems that attend to deprescribing as part of routine clinical practice, additional interventions may confer modest benefits on prescribing without a measurable effect on clinical outcomes.

Falls are a major cause of preventable death, injury, and reduced independence in adults aged 65 years and older. The American Geriatrics Society and British Geriatrics Society (AGS/BGS) published a guideline in 2001, revised in 2011, addressing common risk factors for falls and providing recommendations to reduce fall risk in community-dwelling older adults. In 2022, the World Falls Guidelines (WFG) Task Force created updated, globally oriented fall prevention risk stratification, assessment, management, and interventions for older adults. Our objective was to briefly summarize the new WFG, compare them to the AGS/BGS guideline, and offer suggestions for implementation in the United States. We reviewed 11 of the 12 WFG topics related to community-dwelling older adults and agree with several additions to the prior AGS/BGS guideline, including assessment and intervention for hearing impairment and concern for falling, assessment and individualized exercises for older adults with cognitive impairment, and performing a standardized assessment such as STOPPFall before prescribing a medication that could potentially increase fall risk. Notable areas of difference include: (1) AGS continues to recommend screening all patients aged 65+ annually for falls, rather than just those with a history of falls or through opportunistic case finding; (2) AGS recommends continued use of the Timed Up and Go as a gait assessment, rather than relying on gait speed; and (3) AGS recommends clinical judgment on whether or not to check an ECG for those at risk for falling. Our review and translation of the WFG for a US audience offers guidance for healthcare and other providers and teams to reduce fall risk in older adults.

OBJECTIVE: The growing deprescribing field is challenged by a lack of consensus around evidence and knowledge gaps. The objective of this overview of systematic reviews was to summarize the review evidence for deprescribing interventions in older adults. METHODS: 11 databases were searched from 1st January 2005 to 16th March 2023 to identify systematic reviews. We summarized and synthesized the results in two steps. Step 1 summarized results reported by the included reviews (including meta-analyses). Step 2 involved a narrative synthesis of review results by outcome. Outcomes included medication-related outcomes (e.g., medication reduction, medication appropriateness) or twelve other outcomes (e.g., mortality, adverse events). We summarized outcomes according to subgroups (patient characteristics, intervention type and setting) when direct comparisons were available within the reviews. The quality of included reviews was assessed using A MeaSurement Tool to Assess systematic Reviews 2 (AMSTAR 2). RESULTS: We retrieved 3,228 unique citations and assessed 135 full-text articles for eligibility. Forty-eight reviews (encompassing 17 meta-analyses) were included. Thirty-one of the 48 reviews had a general deprescribing focus, 16 focused on specific medication classes or therapeutic categories and one included both. Twelve of 17 reviews meta-analyzed medication-related outcomes (33 outcomes: 25 favored the intervention, 7 found no difference, 1 favored the comparison). The narrative synthesis indicated that most interventions resulted in some evidence of medication reduction while for other outcomes we found primarily no evidence of an effect. Results were mixed for adverse events and few reviews reported adverse drug withdrawal events. Limited information was available for people with dementia, frailty and multimorbidity. All but one review scored low or critically low on quality assessment. CONCLUSION: Deprescribing interventions likely resulted in medication reduction but evidence on other outcomes, in particular relating to adverse events, or in vulnerable subgroups or settings was limited. Future research should focus on designing studies powered to examine harms, patient-reported outcomes, and effects on vulnerable subgroups. SYSTEMATIC REVIEW REGISTRATION: PROSPERO CRD42020178860.

BACKGROUND: The impact of evidence-based guidelines and controlled trial data on use of cholesterol-lowering medications in older adults is unclear. OBJECTIVE: To examine whether utilization patterns of cholesterol-lowering medications in community-dwelling older adults changed following the release of the National Cholesterol Education Program Adult Treatment Panel III guidelines and results from the Prospective Study of Pravastatin in the Elderly at Risk in 2002. METHODS: Community-dwelling elderly individuals who were enrolled in the Health, Aging and Body Composition Study in 1997-1998 were followed for up to 11 years. An interrupted time series analysis with multivariable generalized estimating equations (GEEs) was used to examine changes in level and trend in cholesterol-lowering medication use before and after 2002, adjusting for sociodemographics, health-related behaviors, and health status. RESULTS: Cholesterol-lowering medication use increased nearly 3-fold from 14.9% in 1997-1998 to 42.6% in 2007-2008, with statins representing the most common class used (87-94%). Multivariable GEE results revealed no significant difference in the level of cholesterol-lowering medication use after 2002 (adjusted OR 0.95; 95% CI 0.89-1.02). Multivariable GEE results revealed that trend changes in the rate of increase in cholesterol-lowering medication declined after 2002 (adjusted ratio of ORs 0.92; 95% CI 0.89-0.95). CONCLUSIONS: The use of cholesterol-lowering medication increased substantially over a decade in community-dwelling elderly individuals but was not related to a change in level or trend following the release of the guidelines and evidence-based data.

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.

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.
