Hurley E, Dalton K, Byrne S, Foley T, Walsh E. Pharmacist-Led Deprescribing Using STOPPFrail for Frail Older Adults in Nursing Homes. J Am Med Dir Assoc 2024; 25:105122. [PMID: 38950585 DOI: 10.1016/j.jamda.2024.105122] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/21/2024] [Revised: 05/24/2024] [Accepted: 05/26/2024] [Indexed: 07/03/2024]
Abstract
OBJECTIVES To evaluate the impact of pharmacist-guided deprescribing using the STOPPFrail (Screening Tool of Older Persons' Prescriptions in Frail adults with a limited life expectancy) criteria in frail older nursing home residents. DESIGN Prospective, unblinded, non-randomized, intervention study. SETTING AND PARTICIPANTS Adults aged ≥65 years with advanced frailty resident in 6 independent nursing homes in Ireland. METHODS STOPPFrail-based deprescribing recommendations were developed by a pharmacist and presented to residents' general practitioners (GPs), who decided to implement or not. Measured outcomes included number of prescribed medications, medication costs, anticholinergic cognitive burden (ACB), drug burden index (DBI), modified medication appropriateness index (MMAI), quality of life (QoL), non-elective hospitalizations, emergency department visits, falls, and mortality were measured at baseline, post review, and at 6 months post review. RESULTS Ninety-nine residents were recruited. Most (94%) were prescribed ≥1 potentially inappropriate medication (PIM). The most frequent PIMs were medications without a clearly documented indication (29.6%) and vitamin D (16.9%). Of 348 recommendations provided to GPs, 203 (58%) were accepted and 193 (55%) were implemented. Relating to baseline, post review, and at 6 months: the mean ± standard deviation (SD) number of medications was 16.0 ± 6.1, 14.6 ± 5.7 (P < .001), and 15.4 ± 5.5 (P < .001). The monthly mean ± SD medication cost per patient was €186.8 ± 123.7, €172.7 ± 119.0 (P < .001), and €186.4 ± 121.2 (P = .95). There were significant post-review decreases in the mean DBI, ACB, and MMAI of 9.7%, 9.6%, and 3.7%, respectively (P < .001), which remained significant at 6 months (P < .001). There were no significant differences in falls, emergency department visits, non-elective hospitalizations, or QoL. CONCLUSIONS AND IMPLICATIONS STOPPFrail-guided deprescribing led by a pharmacist in nursing homes appeared to significantly reduce PIMs, medication costs (initially), and anticholinergic and sedative burdens, without adversely affecting other patient outcomes. Greater consideration should therefore be given to the wider integration of pharmacists into nursing homes to optimize the medications and health outcomes of frail older adults.

[PMID: 38388652 PMCID: PMC10883995 DOI: 10.1038/s41598-024-54879-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/08/2023] [Accepted: 02/17/2024] [Indexed: 02/24/2024] Open
Abstract
Older adults are frequently exposed to medicines with systemic anticholinergic properties, which are linked to increased risk of negative health outcomes. The association between systemic anticholinergics and lung function has not been reported. The aim of this study was to investigate if exposure to systemic anticholinergics influences lung function in older adults. Participants of the southernmost centres of the Swedish National study on Aging and Care (SNAC) were followed from 2001 to 2021. In total, 2936 subjects (2253 from Good Aging in Skåne and 683 from SNAC-B) were included. An extensive medical examination including spirometry assessments was performed during the study visits. The systemic anticholinergic burden was described using the anticholinergic cognitive burden scale. The effect of new use of systemic anticholinergics on the annual change in forced expiratory volume (FEV1s) was estimated using mixed models. During follow-up, 802 (27.3%) participants were exposed to at least one systemic anticholinergic medicine. On average, the FEV1s of participants without systemic anticholinergic exposure decreased 37.2 ml/year (95% CI [33.8; 40.6]) while participants with low and high exposure lose 47.2 ml/year (95% CI [42.4; 52.0]) and 43.7 ml/year (95% CI [25.4; 62.0]). A novel association between new use of medicines with systemic anticholinergic properties and accelerated decrease in lung function in older adults was found. The accelerated decrease is comparable to that observed in smokers. Studies are needed to further explore this potential side effect of systemic anticholinergics.

Protzenko D, Nakache J, De la Brosse S, Honoré S, Hache G. Elderly patients whose hospitalization was medication-related were more likely to receive medication recommendations by clinical pharmacist than patients whose hospitalization was unlikely medication-related in non-geriatric units. Res Social Adm Pharm 2023; 19:1386-1390. [PMID: 37355436 DOI: 10.1016/j.sapharm.2023.06.002] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/13/2022] [Revised: 03/30/2023] [Accepted: 06/10/2023] [Indexed: 06/26/2023]
Abstract
BACKGROUND Elderly patients are often polymedicated, and drug-related hospitalizations are common in this population. In our hospital, pharmacists from the mobile geriatric team (MGT) coordinate medication reviews (MR) for elderly patients hospitalized in non-geriatric wards, to prevent iatrogenic. OBJECTIVE The aim of this work is to determine whether the drug-related origin of hospitalizations can be considered as a targeting criterion for performing MRs. MATERIAL AND METHOD We conducted a retrospective study of data from patients who received a MGT's MR between March 2021 and December 2022, from a single center of more than 1000 beds. The drug-related origin of the hospitalization was estimated as probable or unlikely by the AT-HARM10 tool. Between the two groups, we compared the number of potentially inappropriate prescriptions detected by the PIM-check and START/STOPP tools, drug-drug interactions (DI), unintended discrepancies (UDI) at entry reconciliation, the drug burden index (DBI), and the number of drug-related problems (DRP) i.e., START/STOPP score + DI + UDI. Linear regression of the number of DRP by AT-HARM10 score was computed. RESULTS 110 patients were included. 56 hospitalizations were estimated MRH and 54 non-MRH. Mean age (85.1 ± 7.0), ADL (3.8 ± 1.9), IADL (2.0 ± 1.6), and number of medications at entry (8.9 ± 3.8) were comparable in the 2 groups. Compared with non-MRH group, MRH group had a higher number of START/STOPP criteria (5.7 ± 3.5 vs 3.0 ± 2.6; p < 0.05), PIM-check overuses (2.1 ± 1.7 vs 1.4 ± 1.4; p < 0.05), DI (8.4 ± 9.0 vs 4.7 ± 4.7; p < 0.05), UDI at entry (4.0 ± 3.34 vs 2.2 ± 2.1; p < 0.05), and higher DBI score (0.9 ± 0.7 vs 0.3 ± 0.4; p < 0.05). The number of DRP was higher in group P (17.6 ± 10.8 vs 9.8 ± 6.3; p < 0.00.5). Linear regression showed a positive correlation between AT-HARM10 score and the number of DRP (r = 0.5, p < 0.05) with a coefficient of 7.7 (CI95% = [4.3; 11.1]) and an intercept of 9.8. DISCUSSION These results allow us to consider AT-HARM10 score as a targeting criterion for performing MR for elderly patients, as part of a curative approach to drug iatrogenic for these patients.

Abstract
BACKGROUND Anticholinergic drugs are commonly prescribed, especially to older adults. Anticholinergic burden scales (ABS) have been used to evaluate the cumulative effects of multiple anticholinergics. However, studies have shown inconsistent results regarding the association between anticholinergic burden assessed with ABS and adverse clinical outcomes such as cognitive impairment, functional decline, and frailty. This review aims to identify gaps in research on the development, validation, and evaluation of ABS, and provide recommendations for future studies. METHOD A comprehensive search of five databases (MEDLINE, Embase, PsychInfo, CINAHL, CENTRAL) was conducted for relevant studies published from inception until 25 May 2023. Two reviewers screened for eligibility and assessed the quality of studies using different tools based on the study design and stage of the review framework. Research evidence was evaluated, and gaps were identified and grouped into evidence, knowledge, and methodological gaps, using evidence tables to summarize data. RESULTS Several evidence, knowledge, and methodological gaps in existing development, validation, and evaluation studies of ABS were identified. There is no universally accepted scale, and there is a need to define a clinically relevant threshold for measuring total anticholinergic burden. The current evidence has limitations, underrepresenting low- and middle-income countries, younger individuals, and populations with cognitive disabilities. The impact of anticholinergic burden on frailty is also understudied. Existing evaluation studies provide limited evidence on the benefit of reducing anticholinergic burden on clinical outcomes or the safety of anticholinergic deprescribing. There is also uncertainty regarding optimal reduction, clinically significant anticholinergic burden thresholds, and cost effectiveness. CONCLUSIONS Future research recommendations to bridge knowledge gaps include developing a risk assessment framework, refining ABS scales, establishing a standardized consensus scale, and creating a longitudinal measure of cumulative anticholinergic risk. Strategies to minimize bias, consider frailty, and promote multidisciplinary and multinational collaborations are also necessary to improve patient outcomes.

Abstract
BACKGROUND Medications with anticholinergic and/or sedative properties are commonly used in the management of psychiatric illnesses. The burden of anticholinergic and sedative medication use has been measured by the Drug Burden Index (DBI) score tool. A higher DBI score has been associated with increased risk of falls, bone and hip fractures, and functional and cognitive impairment, among other serious health outcomes, especially in older adults. OBJECTIVES We aimed to describe the drug burden in older adults with psychiatric illnesses using DBI, determine the factors that are associated with the drug burden measured by DBI, and examine the association between DBI score and Katz for activities of daily living (ADL) index. METHODS A cross-sectional study was conducted in the psychogeriatric division of an aged-care home. The study sample comprised all inpatients, aged ≥ 65 years, diagnosed with psychiatric illness. The data obtained included demographic characteristics, duration of hospital stay, primary psychiatric diagnosis and comorbidities, functional status using the Katz ADL index, and cognitive status using the Mini-Mental State Examination (MMSE) score. DBI score was calculated for each anticholinergic and sedative medication used. RESULTS Of the 200 patients eligible for analysis, 106 (53.1%) were females and the mean age was 76 ± 9 years. The most commonly encountered chronic disorders were hypertension 102 (51%) and schizophrenia 94 (47%). The use of drugs with anticholinergic and/or sedative effects was seen in 163 (81.5%) patients; the mean DBI score was 1.25 ± 1. The results of the multinomial logistic regression showed that schizophrenia (odds ratio (OR) = 2.1 (95% confidence interval (CI) 1.57-4.45), p = 0.01), level of dependency (OR = 3.50 (95% CI 1.38-5.70), p = 0.001), and polypharmacy (OR = 2.99 (95% CI 2.15-4.29), p = 0.003) were significantly associated with DBI score ≥ 1 compared to DBI score 0. CONCLUSIONS The study showed that anticholinergic and sedative medication exposure measured by DBI was associated with higher levels of dependency on the Katz ADL index in a sample of older adults with psychiatric illnesses from an aged-care home.

Abstract
OBJECTIVE To estimate the effectiveness, cost effectiveness (to be reported elsewhere), and safety of pharmacy independent prescribers in care homes. DESIGN Cluster randomised controlled trial, with clusters based on triads of a pharmacist independent prescriber, a general practice, and one to three associated care homes. SETTING Care homes across England, Scotland, and Northern Ireland, their associated general practices, and pharmacy independent prescribers, formed into triads. PARTICIPANTS 49 triads and 882 residents were randomised. Participants were care home residents, aged ≥65 years, taking at least one prescribed drug, recruited to 20 residents/triad. INTERVENTION Each pharmacy independent prescriber provided pharmaceutical care to approximately 20 residents across one to three care homes, with weekly visits over six months. Pharmacy independent prescribers developed a pharmaceutical care plan for each resident, did medicines reviews/reconciliation, trained staff, and supported with medicines related procedures, deprescribing, and authorisation of prescriptions. Participants in the control group received usual care. MAIN OUTCOMES MEASURES The primary outcome was fall rate/person at six months analysed by intention to treat, adjusted for prognostic variables. Secondary outcomes included quality of life (EQ-5D by proxy), Barthel score, Drug Burden Index, hospital admissions, and mortality. Assuming a 21% reduction in falls, 880 residents were needed, allowing for 20% attrition. RESULTS The average age of participants at study entry was 85 years; 70% were female. 697 falls (1.55 per resident) were recorded in the intervention group and 538 falls (1.26 per resident) in the control group at six months. The fall rate risk ratio for the intervention group compared with the control group was not significant (0.91, 95% confidence interval 0.66 to 1.26) after adjustment for all model covariates. Secondary outcomes were not significantly different between groups, with exception of the Drug Burden Index, which significantly favoured the intervention. A third (185/566; 32.7%) of pharmacy independent prescriber interventions involved medicines associated with falls. No adverse events or safety concerns were identified. CONCLUSIONS Change in the primary outcome of falls was not significant. Limiting follow-up to six months combined with a small proportion of interventions predicted to affect falls may explain this. A significant reduction in the Drug Burden Index was realised and would be predicted to yield future clinical benefits for patients. This large trial of an intensive weekly pharmacist intervention with care home residents was also found to be safe and well received. TRIAL REGISTRATION ISRCTN 17847169.

Exposure to anticholinergic and sedative medication is associated with impaired functioning in older people with vertigo, dizziness and balance disorders-Results from the longitudinal multicenter study MobilE-TRA. Front Pharmacol 2023; 14:1136757. [PMID: 36937862 PMCID: PMC10020174 DOI: 10.3389/fphar.2023.1136757] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/03/2023] [Accepted: 02/20/2023] [Indexed: 03/06/2023] Open
Abstract
Introduction: Anticholinergic and sedative medication is prescribed for various conditions in older patients. While the general association between anticholinergic and sedative medication and impaired functioning is well established, its specific role in older individuals with vertigo, dizziness, and balance disorders (VDB) is still incompletely understood. The objective of this study was to investigate, whether an exposure to anticholinergic and sedative medication is associated with lower generic and lower vertigo-specific functioning in older patients with VDB. Methods: Data originates from the longitudinal multicenter study MobilE-TRA with two follow-ups, conducted from 2017 to 2019 in two German federal states. Exposure to anticholinergic and sedative medication was quantified using the drug burden index (DBI). Generic functioning was assessed by the Health Assessment Questionnaire Disability Index, appraising the amount of difficulties in performing activities of daily living (ADL). Vertigo-specific functioning was measured using the Vestibular Activities and Participation (VAP) questionnaire, assessing patient-reported functioning regarding activities of daily living that are difficult to perform because of their propensity to provoke VDB (Scale 1) as well as immediate consequences of VDB on activities and participation related to mobility (Scale 2). Longitudinal linear mixed models were applied to assess the association of exposure to anticholinergic and sedative medication at baseline and the level of generic and vertigo-specific functioning status over time. Results: An overall of 19 (7 from Bavaria) primary care physicians (mean age = 54 years, 29% female) recruited 158 (59% from Bavaria) patients with VDB (median age = 78 years, 70% female). Anticholinergic and sedative medication at baseline was present in 56 (35%) patients. An exposure to anticholinergic and sedative medication at baseline was significantly associated with lower generic functioning [Beta = 0.40, 95%-CI (0.18; 0.61)] and lower vertigo-specific functioning [VAP Scale 1: Beta = 2.47, 95%-CI (0.92; 4.02)], and VAP Scale 2: Beta = 3.74, 95%-CI [2.23; 5.24]). Conclusion: Our results highlight the importance of a close monitoring of anticholinergic and sedative medication use in older patients with VDB. When feasible, anticholinergic and sedative medication should be replaced by equivalent alternative therapies in order to potentially reduce the burden of VDB.

Abstract
PURPOSE To inform recommendations by the Canadian Task Force on Preventive Health Care on potentially inappropriate prescribing and over-the-counter (OTC) medication use among adults aged 65 years and older in primary care settings. This protocol outlines the planned scope and methods for a systematic review of the benefits and harms and acceptability of interventions to reduce potentially inappropriate prescriptions and OTC medication use. METHODS De novo systematic reviews will be conducted to synthesize the available evidence on (a) the benefits and harms of interventions to reduce potentially inappropriate prescriptions and OTC medications compared to no intervention, usual care, or non- or minimally active intervention among adults aged 65 years and older and (b) the acceptability of these interventions or attributes among patients. Outcomes of interest for the benefits and harms review are all-cause mortality, hospitalization, non-serious adverse drug reactions, quality of life, emergency department visits, injurious falls, medical visits, and the number of medications (and number of pills). Outcomes for the acceptability review are the preference for and relative importance of different interventions or their attributes. For the benefits and harms review, we will search MEDLINE, Embase, and Cochrane Central Register of Controlled Trials for randomized controlled trials. For the acceptability review, we will search MEDLINE, Embase, PsycInfo, Cochrane Central Register of Controlled Trials, and the NHS Economic Evaluation Database for experimental and observational studies with a comparator. Websites of relevant organizations, other grey literature sources, and reference lists of included studies and reviews will be searched. Title and abstract screening will be completed by two independent reviewers using the liberal accelerated approach. Full-text review, data extraction, risk of bias assessments, and GRADE (Grading of Recommendations Assessment, Development and Evaluation) will be completed independently by two reviewers, with any disagreements resolved by consensus or by consulting with a third reviewer. The GRADE approach will be used to assess the certainty of the evidence for outcomes. DISCUSSION The results of this systematic review will be used by the Canadian Task Force on Preventive Health Care to inform their recommendation on potentially inappropriate prescribing and OTC medication use among adults aged 65 years and older.

Abstract
Currently, the management of comorbidities and polypharmacy in HIV-infected patients requires a coordinated action, with special focus on gender differences. Observational, cross-sectional study was conducted to study the HIV population from Menorca (Illes Balears). Adult HIV-positive individuals on antiretroviral treatment attending the pharmacy service from Hospital Mateu Orfila (Menorca) were included. In a single visit, demographical and clinical characteristics, comorbidities and cotreatments were collected. Anticholinergic burden (Drug Burden Index, DBI), drug-to-drug interactions (BOT PLUS database) and symptoms associated with HIV treatment (HIV-SI index) were assessed. A total of 223 patients were included, 68.2% men, with a median age of 53.00 (44.50-58.00) years, median BMI of 24.07, 47.73% smokers and 9.90% drug consumers. Women had more advanced stages of the disease and significantly more symptoms (cough and anxiety) versus men (p = .033 and p = .048, respectively). Moreover higher exposures to anticholinergic drugs (DBI 0.51 vs. 0.27) were reported, together with more frequency of drug-to-drug interactions (57.7% vs. 37.5%; p = .005) that increased with age. Red interactions were more frequently reported in PI (2.69%), NNRTIs (1.92%) and booster drugs (1.92%). These results support the need to implement specific measures for the management of HIV-infected women and tools to assess polypharmacy and risk of drug-to-drug interactions.

Effects of anticholinergic and sedative medication use on fractures: A self-controlled design study. J Am Geriatr Soc 2021; 69:3212-3224. [PMID: 34291817 PMCID: PMC8595585 DOI: 10.1111/jgs.17377] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/11/2021] [Revised: 05/20/2021] [Accepted: 06/15/2021] [Indexed: 11/28/2022]
Abstract
BACKGROUND/OBJECTIVES Unintentional falls are a leading cause of injury for older adults, and evidence is needed to understand modifiable risk factors. We evaluated 1-year fall-related fracture risk and whether dispensing of medications with anticholinergic/sedating properties is temporally associated with an increased odds of these fractures. DESIGN A retrospective cohort study with nested self-controlled analyses conducted between January 1, 2014, and December 31, 2016. SETTING Twenty percent nationwide, random sample of US Medicare beneficiaries. PARTICIPANTS New users of medications with anticholinergic/sedating properties who were 66+ years old and had Medicare Parts A, B, and D coverage but no claims for medications with anticholinergic/sedating properties in the year before initiation were eligible. MEASUREMENTS We followed new users of medications with anticholinergic/sedating properties until first non-vertebral, fall-related fracture (primary outcome), Medicare disenrollment, death, or end of study data. We estimated the 1-year risk with corresponding 95% confidence intervals (CIs) of first fracture after new use. We applied the self-controlled case-crossover and case-time-control designs to estimate odds ratios (ORs) and 95% CIs by comparing anticholinergic and/or sedating medication exposure (any vs. none) during a 14-day hazard period preceding the fracture to exposure to these medications during an earlier 14-day control period. RESULTS A total of 1,097,989 Medicare beneficiaries initiated medications with anticholinergic/sedating properties in the study period. The 1-year cumulative incidence of fall-related fracture, accounting for death as a competing risk, was 5.0% (95% CI: 5.0%-5.0%). Using the case-crossover design (n = 41,889), the adjusted OR for the association between anticholinergic/sedating medications and fractures was 1.03 (95% CI: 0.99, 1.08). Accounting for the noted temporal trend using the case-time-control design (n = 209,395), the adjusted OR was 1.60 (95% CI: 1.52, 1.69). CONCLUSION Use of anticholinergic/sedating medication was temporally associated with an increased odds of fall-related fractures. Patients and their healthcare providers should consider pharmacologic and non-pharmacologic treatments for the target condition that are safer.

Abstract
Aim: To compare anticholinergic burden (ACB) in older patients with and without cancer and evaluate the effects of ACB on geriatric syndromes. Methods: A total of 291 patients from the geriatric clinic and 301 patients from the oncology clinic were evaluated. ACB <2 was categorized as low ACB and ACB ≥2 was categorized as high ACB. A comprehensive geriatric assessment was performed on patients from the geriatric clinic. Results: ACB scores were significantly higher in patients without cancer compared with those with cancer (p < 0.005). Number of falls and Geriatric Depression Scale 15 scores were higher and Mini-Nutritional Assessment and Barthel/Lawton activities of daily living scores were lower in geriatric patients with high ACB scores compared with those with low ACB scores (p < 0.005). Conclusion: It is crucial to understand the potential effects of ACB for rational drug use and optimum cancer management in older patients with cancer.

Abstract
Background Older patients are at increased risk of drug-drug interactions (DDIs) due to polypharmacy. Cardiovascular and central nervous system (CNS) drugs are commonly implicated in serious DDIs. Objectives This study aimed to determine the prevalence and factors associated with potential ‘severe’ cardiovascular and CNS DDIs among older (≥ 70 years) community-dwellers. Methods This was a prospective cohort study using linked data from a national pharmacy claims database and waves 1 and 2 of The Irish LongituDinal study on Ageing (TILDA). ‘Severe’ cardiovascular and CNS DDIs were identified using the British National Formulary 77 and Stockley’s Drug Interactions. The prevalence of ‘severe’ DDIs (any DDI vs. none) was calculated. Logistic regression was used to examine the association between sociodemographic, functional ability, and medication-related factors and the risk of DDI exposure between waves 1 and 2. Results A total of 1466 patients were included [mean age (standard deviation) = 78 (5.5) years; female n = 795, 54.2%]. In total, 332 community-dwellers aged ≥ 70 years [22.65%, 95% confidence interval (CI) 20.58–24.86] were potentially exposed to at least one ‘severe’ cardiovascular or CNS DDI, with more than half (54.82%) of this cohort dispensed the same DDI for a prolonged time (≥ 3 consecutive claims). Aspirin-warfarin was the most frequently dispensed (co-prescribed) DDI (n = 34, 10.24%, 95% CI 7.39–14.00), followed by atorvastatin-clarithromycin (n = 19, 5.72%, 95% CI 3.64–8.81). Polypharmacy [≥ 10 vs. < 5 drugs, odds ratio (OR) 13.40, 95% CI 8.22–21.85] and depression (depressed vs. not, OR 2.12, 95% CI 1.34–3.34) were significantly associated with these DDIs, after multivariable adjustment. Conclusion ‘Severe’ cardiovascular and CNS DDIs are prevalent in older community-dwellers in Ireland, and those with polypharmacy and depression are at a significantly increased risk.

Abstract
INTRODUCTION Medication safety is a vital aim in older adults' pharmacotherapy. Increased morbidity and vulnerability require particularly careful prescribing. Beneath avoiding unnecessary polypharmacy and prescribing omissions, physicians have to be aware of potentially inappropriate medications (PIMs) and related outcomes to optimize older adults' drug therapy, and to reduce adverse drug events. OBJECTIVE The aim of this study was to identify participants characteristics associated with PIM use and associations of PIM use with functional capacity with a focus on sex differences. METHODS Multivariable logistic regression analyses of cross-sectional Berlin Aging Study II (BASE-II) data (N = 1,382, median age 69 years, interquartile range 67-71, 51.3% women) were performed with PIM classification according to the EU(7)-PIM list. RESULTS In the overall study population, higher education was associated with lower odds of PIM use (odds ratio [OR] 0.93, confidence interval [CI] 95% 0.87-0.99, p = 0.017). Falls (OR 1.53, CI 95% 1.08-2.17, p = 0.016), frailty/prefrailty (OR 1.68, 1.17-2.41, p = 0.005), and depression (OR 2.12, CI 95% 1.32-3.41, p = 0.002) were associated with increased odds of PIM use. A better nutritional status was associated with lower odds of PIM use (OR 0.88, CI 95% 0.81-0.97, p = 0.008). In the sex-stratified analysis, higher education was associated with lower odds of PIM use in men (OR 0.90, CI 95% 0.82-0.99, p = 0.032). Frailty/prefrailty was associated with increased odds of PIM use in men (OR 2.04, CI 95% 1.18-3.54, p = 0.011) and a better nutritional status was associated with lower odds of PIM use in men (OR 0.83, CI 95% 0.72-0.96, p = 0.011). Falls in the past 12 months were related to an increased prevalence of PIM use in women (OR 1.74, CI 95% 1.10-2.75, p = 0.019). Depression was associated with a higher prevalence of PIM use in both men (OR 2.74, CI 95% 1.20-6.24, p = 0.016) and women (OR 2.06, CI 95% 1.14-3.71, p = 0.017). We did not detect sex differences regarding the overall use of drugs with anticholinergic effects, but more men than women used PIMs referring to the cardiovascular system (p = 0.036), while more women than men used PIMs referring to the genitourinary system and sex hormones (p < 0.001). CONCLUSION We found similarities, but also differences between men and women as to the associations between PIM use and participants' characteristics and functional capacity assessments. The association of lower education with PIM use may suggest that physicians' prescribing behavior is modified by patient education, a relationship that could evolve from more critical attitudes of educated patients towards medication use. We conclude that sex differences in associations of PIM use with functional capacities might be partly attributable to sex differences in drug classes used, but not with regard to anticholinergics, as these are used to a similar extent in men and women in the cohort studied here.

Abstract
Purpose The cumulative effect of medication inhibiting acetylcholine activity—also known as anticholinergic burden (AB)—can lead to functional and cognitive decline, falls, and death. Given that studies on the population prevalence of AB are rare, we aimed to describe it in a large and unselected population sample. Methods Using the German Pharmacoepidemiological Research Database (GePaRD) with claims data from ~20% of the German population we analyzed outpatient drug dispensations in 2016. Based on the Anticholinergic Cognitive Burden (ACB) scale, we classified persons into four categories and determined the cumulative AB as continuous variable. Results Among 16,470,946 persons (54% female), the prevalence of clinically relevant AB (ACB≥3) was 10% (women) and 7% (men). Below age 40 it was highest in persons ≤18 years (6% both sexes). At older ages (50–59 vs. 90–99 years), prevalence of ACB≥3 increased from 7% to 26% (men) and from 10% to 32% (women). Medication classes contributing to the cumulative AB differed by age: antihistamines, antibiotics, glucocorticoids (≤19 years), antidepressants (20–49 years), antidepressants, cardiovascular medication, antidiabetics (50–64 years), and additionally medication for urinary incontinence/overactive bladder (≥65 years). Medication dispensed by general physicians contributed most to the cumulative AB. Conclusion Although a clinically relevant AB is particularly common in older persons, prevalence in younger age groups was up to 7%. Given the risks associated with AB in older persons, targeted interventions at the prescriber level are needed. Furthermore, risks associated with AB in younger persons should be explored.

Abstract
BACKGROUND It is well established that individual medications that affect the central nervous system (CNS) increase falls risk in older adults. However, less is known about risks associated with taking multiple CNS-active medications. METHODS Employing a new user design, we used data from the Adult Changes in Thought study, a prospective cohort of community-dwelling people aged 65 and older without dementia. We created a time-varying composite measure of CNS-active medication exposure from electronic pharmacy fill data and categorized into mutually exclusive categories: current (within prior 30 days), recent (31-90 days), past (91-365 days), or nonuse (no exposure in prior year). We calculated standardized daily dose and identified new initiation. Cox proportional hazards models examined the associations between exposures and the outcome of fall-related injury identified from health plan electronic databases. RESULTS Two thousand five hundred ninety-five people had 624 fall-related injuries over 15,531 person-years of follow-up. Relative to nonuse, fall-related injury risk was significantly greater for current use of CNS-active medication (hazard ratio [HR] = 1.95; 95% CI = 1.57-2.42), but not for recent or past use. Among current users, increased risk was noted with all doses. Risk was increased for new initiation compared with no current use (HR = 2.81; 95% CI = 2.09-3.78). Post hoc analyses revealed that risk was especially elevated with new initiation of opioids. CONCLUSIONS We found that current use, especially new initiation, of CNS-active medications was associated with fall-related injury in community-dwelling older adults. Increased risk was noted with all dose categories. Risk was particularly increased with new initiation of opioids.

Abstract
BACKGROUND AND OBJECTIVE Dementia is one of the most frequent diseases in the elderly, being its prevalence of up to 64% in institutionalized people. In this population, in addition to antidementia drugs, it is common to prescribe drugs with anticholinergic/sedative burden that, due to their adverse effects, could worsen their functionality and cognitive status. The objective is to estimate the prevalence of the use of drugs with anticholinergic/ sedative burden in institutionalized older adults with dementia and to assess the associated factors. MATERIALS AND METHODS A cross-sectional study developed in older with dementia living in nursing homes. The prevalence of prescription of anticholinergic/sedative drugs was estimated according to the Drug Burden Index (DBI). A comparative analysis of the DBI score was performed between different types of dementia as well as among various factors and according to the anticholinergic/sedative risk, establishing as a cut-off point of DBI≥1 (high anticholinergic/sedative risk). RESULTS 178 residents were included. 83.7% had some drug with anticholinergic/sedative burden according to DBI. 50% had a DBI≥1 score. Residents with vascular dementia had a mean DBI of 1.34 (SD 0.84), a significantly higher score than residents with Alzheimer's disease (0.41, 95% CI 0.04-0.78).). Likewise, a higher DBI was associated with more polypharmacy (3.36; 95% CI 2.64-4.08), more falls, hospital admissions and emergency room visits (P<.05). CONCLUSIONS Polypharmacy and prescription of anticholinergic/sedative drugs is frequent among institutionalized older adults with dementia, finding an association between DBI, falls and hospital admissions or emergency department visits. Therefore, it is necessary to propose interdisciplinary pharmacotherapeutic optimization strategies.

Quantifying cumulative anticholinergic and sedative drug load among US Medicare Beneficiaries. Pharmacoepidemiol Drug Saf 2020; 30:144-156. [PMID: 33000867 DOI: 10.1002/pds.5144] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/25/2020] [Revised: 09/16/2020] [Accepted: 09/22/2020] [Indexed: 12/15/2022]
Abstract
PURPOSE Medications with anticholinergic and sedative properties are widely used among older adults despite strong evidence of harm. The drug burden index (DBI), a pharmacological screening tool, measures these properties across drug classes, and higher DBI drug exposure (DBI > 1) has been associated with certain physical function-related adverse events. Our aim was to quantify mean daily DBI drug exposure among older adults in the United States (US). METHODS We screened medications for DBI properties and operationalized the DBI for US Medicare claims. We then conducted a retrospective cohort study of a 20% random, nationwide sample of 4 137 384 fee-for-service Medicare beneficiaries aged 66+ years (134 757 039 person-months) from January 2013 to December 2016. We measured the monthly distribution based on mean daily DBI, categorized as (a) >0 vs 0 (any use) and (b) 0, 0 < DBI ≤ 1, 1 < DBI ≤ 2, and DBI > 2, and examined temporal trends. We described patient-level factors (eg, demographics, healthcare use) associated with high (>2) vs low (0 < DBI≤1) DBI drug exposure. RESULTS The distribution of the mean daily DBI, aggregated at the month-level, was: 58.1% DBI = 0, 29.0% 0 < DBI≤1, 9.3% 1 < DBI≤2, and 3.7% DBI > 2. Predictors of high monthly DBI drug exposure (DBI > 2) included certain indicators of increased healthcare use (eg, high number of drug claims), white race, younger age, frailty, and a psychosis diagnosis code. CONCLUSIONS The predictors of high DBI drug exposure can inform discussions between patients and providers about medication appropriateness and potential de-prescribing. Future Medicare-based studies should assess the association between the DBI and adverse events.

Potentially inappropriate medications in Chinese older adults: a comparison of two updated Beers criteria. Int J Clin Pharm 2020; 43:229-235. [PMID: 32920684 DOI: 10.1007/s11096-020-01139-5] [Citation(s) in RCA: 14] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/12/2019] [Revised: 08/22/2020] [Accepted: 08/25/2020] [Indexed: 10/23/2022]
Abstract
Background Beers criteria have been into the mainstay to characterize the potentially inappropriate medication since its first publication, but the recent version, Beers 2019, is yet to be validated by clinical studies nationally. Objective To identify the prevalence and the predictors of potentially inappropriate medications in hospitalized geriatric patients based on the Beers 2019 and 2015 criteria. Setting Nanjing Drum Tower Hospital, a 3000-bed tertiary care teaching hospital in China. Method We conducted a cross-sectional study from July 1, 2018 to December 31, 2018. Data from all hospitalized patients aged ≥ 65 years were collected from the hospital database. Inappropriate prescriptions were identified using the Beers 2019 criteria and the Beers 2015 criteria. Main outcome measure Prevalence Ratio (PR) and predictors of potentially inappropriate medications. Results The prevalence of inappropriate prescriptions based on the Beers 2019 criteria was 64.80%. This result was slightly higher than that of the Beers 2015 criteria (64.31%). The most commonly encountered inappropriate prescriptions identified using the two criteria were proton-pump inhibitors. The kappa coefficient was 0.826 (p < 0.001) indicating a strong coherence between the two criteria. The most important factor associated with inappropriate medications use was the number of prescribed drugs (PR 5.17, 95% CI 2.89-8.43; PR 4.58, 95% CI 1.93-7.25). Conclusion This study showed a high prevalence of potentially inappropriate medication in the Chinese geriatric population, which was associated with the number of prescribed drugs. The predictors identified in this research might help pharmacists to detect high-risk drugs and intervene in time.

Abstract
BACKGROUND The Drug Burden Index (DBI) was developed to assess patient exposure to medications associated with an increased risk of falling. The objective of this study was to examine the association between the DBI and medication-related fall risk. METHODS The study used a retrospective cohort design, with a 1-year observation period. Participants (n = 1562) were identified from 31 community pharmacies. We examined the association between DBI scores and four outcomes. Our primary outcome, which was limited to participants who received a medication review, indexed whether the review resulted in at least one medication-related recommendation (e.g., discontinue medication) being communicated to the participant's health care provider. Secondary outcomes indexed whether participants in the full sample: (1) screened positive for fall risk, (2) reported 1+ falls in the past year, and (3) reported 1+ injurious falls in the past year. All outcome variables were dichotomous (yes/no). RESULTS Among those who received a medication review (n = 387), the percentage of patients receiving at least one medication-related recommendation ranged from 10.2% among those with DBI scores of 0 compared to 60.2% among those with DBI scores ≥1.0 (Chi-square (4)=42.4, p < 0.0001). Among those screened for fall risk (n = 1058), DBI scores were higher among those who screened positive compared to those who did not (Means = 0.98 (SD = 1.00) versus 0.59 (SD = 0.74), respectively, p < 0.0001). CONCLUSION Our findings suggest that the DBI is a useful tool that could be used to improve future research and practice by focusing limited resources on those individuals at greatest risk of medication-related falls.

Abstract
PURPOSE OF THE STUDY Frailty leads to serious adverse outcomes including falls. The relationship between frailty and falls has not been evaluated in the context of the side effects of drugs with anticholinergic properties. The aim of this study was to examine the potential association of anticholinergic burden (ACB) with the risk of falls among frail older adults. DESIGN AND METHODS Community-dwelling older adults were consecutively selected from the geriatrics outpatient clinic. Based on a fall history in the last 12 months, the participants were grouped as fallers and non-fallers. Frailty status was assessed by Fried's phenotype method. Exposure to anticholinergic medications was estimated using the ACB scale, and the participants were classified into ACB_0 (none), ACB_1 (possible) and ACB_2+ (definite). RESULTS The study included 520 older adults (mean age 77.7 years, 62.7 % female), with a fall prevalence of 25.8 % 12 months past. The proportions of frailty and pre-frailty were 33.1 % and 57.4 %, respectively. After adjustment for study confounders, receiving at least 1 drug with either possible or definite anticholinergic properties was independently associated to falls in frail [OR = 3.84 (1.48-9.93), p = 0.006] and pre-frail participants [OR = 2.71 (1.25-5.89); p = 0.012], but not in robust subjects. Moreover, ACB was significantly associated with the frailty components on adjusted analysis (p's<0.05). IMPLICATIONS Current study showed that the use of any drugs with possible or definite anticholinergic properties was associated with an increased risk of falls in frail older adults. The results emphasize the importance of medication management with respect to fall prevention in these patients.

Abstract
OBJECTIVES To evaluate the effects of a community pharmacy-based fall prevention intervention (STEADI-Rx) on the risk of falling and use of medications associated with an increased risk of falling. DESIGN Randomized controlled trial. SETTING A total of 65 community pharmacies in North Carolina (NC). PARTICIPANTS Adults (age ≥65 years) using either four or more chronic medications or one or more medications associated with an increased risk of falling (n = 10,565). INTERVENTION Pharmacy staff screened patients for fall risk using questions from the Stopping Elderly Accidents, Deaths, and Injuries (STEADI) algorithm. Patients who screened positive were eligible to receive a pharmacist-conducted medication review, with recommendations sent to patients' healthcare providers following the review. MEASUREMENTS At intervention pharmacies, pharmacy staff used standardized forms to record participant responses to screening questions and information concerning the medication reviews. For participants with continuous Medicare Part D/NC Medicaid coverage (n = 3,212), the Drug Burden Index (DBI) was used to assess exposure to high-risk medications, and insurance claims records for emergency department visits and hospitalizations were used to assess falls. RESULTS Among intervention group participants (n = 4,719), 73% (n = 3,437) were screened for fall risk. Among those who screened positive (n = 1,901), 72% (n = 1,373) received a medication review; and 27% (n = 521) had at least one medication-related recommendation communicated to their healthcare provider(s) following the review. A total of 716 specific medication recommendations were made. DBI scores decreased from the pre- to postintervention period in both the control and the intervention group. However, the amount of change over time did not differ between these two groups (P = .66). Risk of falling did not change between the pre- to postintervention period or differ between groups (P = .58). CONCLUSION We successfully implemented STEADI-Rx in the community pharmacy setting. However, we found no differences in fall risk or the use of medications associated with increased risk of falling between the intervention and control groups. J Am Geriatr Soc 68:1778-1786, 2020.

Abstract
The use of anticholinergic medications by residents in aged care homes is associated with increased risk of adverse effects. These include cognitive impairment, sleep disturbances, and falls, and necessitate increased healthcare visits and the associated burden on healthcare systems. The objective of this study was to investigate associations between anticholinergic burden and health outcomes such as independence in activities for daily living, frailty, quality of life, and sleep quality. The study was conducted among residents in Malaysian aged care homes, aged 60 years and above. Anticholinergic burden was calculated using the Anticholinergic Cognitive Burden (ACB) scale. Health outcome measures included independence, assessed using the Katz Activities for Daily Living scale (Katz ADL); quality of life, assessed using the Older People’s Quality of Life Questionnaire (OPQOL); frailty, assessed using the Groningen Frailty Index (GFI); and sleep quality, measured using the Pittsburg Sleep Quality Index (PSQI). Just over one-third (36%) of the study population was exposed to at least one medication with anticholinergic effect. An increased anticholinergic cognitive burden was associated with frailty (p = 0.031), sleep latency (p = 0.007), and sleep disturbances (p = 0.015). Further studies are required to assess the effect of prolonged exposure to anticholinergic medications on health outcomes.
