Fall-Risk-Increasing Drugs: A Systematic Review and Meta-Analysis: I. Cardiovascular Drugs

Preadmission medications and recent falls in older inpatients: an observational study

BACKGROUND

Falls in older adults might increase due to polypharmacy.

AIM

This study aimed to explore the association between preadmission medications and history of falls in older inpatients.

METHOD

This observational study of inpatients aged ≥ 65 years was conducted over 4 years at Ballina Hospital, Australia. The Medication Regimen Complexity Index (MRCI), Drug Burden Index (DBI), and Anticholinergic Effect on Cognition (AEC) scores were calculated for preadmission medications. Polypharmacy and falls questionnaires were administered to identify falls in the past 6 months and aptitude toward medication use.

RESULTS

Overall, 194 participants with a mean age of 80.2 (SD 8.0) years were included. The mean daily number of regular medications was 7.8 (SD 3.9) and the mean MRCI score was 22 (SD 12.6). Among the participants, 107 (55%) reported falls in the past 6 months and 47 (24%) reported ≥ 2 falls. Age and hearing impairment were positively associated with falls (p = 0.007 and p = 0.003, respectively). History of falls was positively associated with a MRCI score of ≥ 20 (p = 0.018), an AEC score of ≥ 2 (p = 0.010) and a DBI score of ≥ 1 after adjustment for age (p = 0.041). Forgetting medications was associated with falls (p = 0.043). Antihypertensive use did not increase falls risk.

CONCLUSION

Implementing a decisive approach to simplify complex medication regimens, along with patient-focused medication management strategies, may help reduce the risk of falls in older adults. Sedatives and anticholinergic medications increase the risk of falls and should be avoided whenever possible.

Drug-related falls: proportion and impact of hospitalizations in geriatric departments on the prescription of fall-risk increasing drugs (FRIDs)

PURPOSE

The incidence of drug-related admissions in France was 8.5% in 2018, with falls being the 5 th cause of DRA. The screening of adverse drug reactions (ADRs) in old adults can be challenging. Our objective was to determine the proportion of old patients hospitalized for drug-related falls in a geriatrics department, assess their preventability and the impact of hospitalizations on the prescription of fall-risk increasing drugs (FRIDs).

METHODS

A retrospective observational study, including patients aged over 75 years who were admitted to an acute geriatrics medicine department from May 10, 2022, to February 2, 2023, was conducted. We used a previously published method to detect DRA and assess their preventability.

RESULTS

Of the 512 patients admitted to the department during the study period, 104 patients (20%) were hospitalized due to falls, of whom 71 (14%) were considered to be drug-related. Falls associated with drugs were categorized as more severe (p = 0.01). In 41% of drug-related falls, ADRs were considered to be definitively avoidable. The most commonly implicated FRIDs classes were beta-blockers (53%, n = 38); diuretics (47%, n = 34); antidepressants (41%, n = 29); benzodiazepines (6%, n = 20); and underuse of vitamin D in patients with a documented deficiency (65%, n = 46). In patients hospitalized for drug-related falls, the FRIDs decreased between admission (n = 314) and discharge (n = 198, p < 0.01).

CONCLUSION

The proportion of hospitalizations for drug-related falls is notably high in geriatric department, and a substantial proportion can be prevented. These findings emphasize the importance of targeting high-risk patients for falls and implementing preventive measures, such as reassessing their medication as recommended in the latest international guidelines for falls prevention.

The association between statins and gait speed reserve in older adults: effects of concomitant medication

Statins are frequently prescribed to older adults, yet their effects on ageing phenotypes such as frailty or physiological reserves remain poorly understood. Gait Speed Reserve (GSR), defined as the difference between maximal and usual gait speeds, serves as an indicator of physiological reserve, reflecting the body's ability to perform beyond baseline functional levels. Polypharmacy, prevalent in this population, may contribute to inconsistent findings through interactions between statins and concomitant medications. We aimed to investigate how concomitant medications moderate the association between statin use and GSR in older adults. To this end, we conducted a cross-sectional observational cohort study using data from the Mobility Center at the University Department of Geriatric Medicine FELIX PLATTER, Basel, Switzerland (n = 5519 adults aged ≥ 60 years). Moderation regression analyses with propensity score weighting were used to evaluate the effect of concomitant medications on the association between statin use and GSR. Results showed statin use was associated with a lower GSR compared to non-use (- 1.9 cm/s [95% CI, - 3.1 to - 0.72]). However, ACE inhibitors and aspirin significantly influenced this association. The GSR difference for statin users compared to non-users increased by 3.7 cm/s (from - 2.2 to 1.5 cm/s; 95% CI, 0.0 to 7.4) with concomitant ACE inhibitor use and by 5.8 cm/s (from - 3.4 to 2.3 cm/s; 95% CI, 2.5 to 9.1) with aspirin use. We found no statistically significant association between statin use and usual gait speed, the secondary outcome. In conclusion, ACE inhibitors and aspirin interacted with statins, reversing the negative association with GSR into a positive one when co-used. Future clinical trials are needed to determine causality and further investigate the impact of concomitant medication use on statin effects in aging populations. Meanwhile, our findings underscore the importance of considering concomitant medication use when assessing the effects of statins in older adults.

The association between STOPPFall medication use and falls and fractures in community-dwelling older people

INTRODUCTION

Falls and fractures are common among older people. The Screening Tool of Older Persons Prescriptions in older adults with high fall risk (STOPPFall) provides a comprehensive list of fall-risk-increasing drugs (FRIDs). This study assesses the association between STOPPFall medications and future falls/fractures among a large cohort of community-dwelling people ≥65 years using The Irish Longitudinal Study on Ageing (TILDA) Waves 1-6, collected from 2009 to 2021.

METHODS

STOPPFall medications were recorded at Wave 1 and Wave 3. Falls/fractures were self-reported. Logistic regression models reporting odds ratios (ORs) assessed the association between STOPPFall medications and falls (including injurious/unexplained falls) and fractures at follow-up, adjusted for relevant covariates.

RESULTS

Over one in four participants (777/2898, 27%) were prescribed one STOPPFall medication, and 15% (421/2898) were prescribed ≥2 STOPPFall medications. Over half of participants fell during follow-up, with 1/5 sustaining any fracture. Prescription of ≥2 STOPPFall medications was independently associated with all falls [OR 1.67 (95%CI 1.28-2.18); P < 0.001], injurious falls [OR 1.53 (95%CI 1.19-1.97); P = 0.001], unexplained falls [OR 1.86 (95%CI 1.43-2.42); P < 0.001], all fractures [OR 1.59 (95%CI 1.20-2.12); P = 0.001] and hip fractures [OR 1.75 (95%CI 1.00-3.05); P = 0.048]. Increasing prescription of ≥2 STOPPFall medications at Wave 3 was associated with increased likelihood of all falls and injurious falls.

CONCLUSION

Prescription of ≥2 STOPPFall medications is independently associated with an increased likelihood of all falls and all fractures. This is a potentially modifiable risk factor for falls, and an increased falls risk should be considered when prescribing these medications.

Healthy ageing in older adults with cardiovascular disease

As life expectancy continues to increase due to advancements in medical technology, public health, nutrition, and socioeconomic progress, the population of older adults in the USA and Europe is rapidly growing. By 2050, individuals aged 65 and older are projected to constitute over 20% of the US population and 29% of the European population, leading to a higher prevalence of chronic diseases, including cardiovascular disease. Cardiovascular disease, the leading cause of death in the USA, poses significant challenges to healthy ageing by contributing to accelerated biological ageing and the development of geriatric syndromes. This state-of-the-art review aims to (i) define healthy ageing for older patients living with cardiovascular disease; (ii) compare chronological vs biological ageing as it pertains to cardiovascular disease; (iii) describe the impact of geriatric syndromes and provide an approach to management and prevention; and (iv) address the gaps in knowledge and future directions for potential interventions that could promote healthy ageing.

Fall Risk-Increasing Drugs and Fall-Related Injuries among Older Adults in Ontario: A Population-Based Matched Case-Control Study

OBJECTIVES

Commonly prescribed medications individually increase the risk of falls. Less is known about the association between multiple fall risk-increasing drug (FRID) use and falls. We examined the association between 12 major FRID classes, alone and in combination and fall-related injuries among older adults in home care (HC) and long-term care (LTC) settings.

DESIGN

Matched, case-control study.

SETTING AND PARTICIPANTS

HC recipients and LTC residents in Ontario, Canada, from 2008 to 2016.

METHODS

Cases were matched to controls by sex, age, history of falls, calendar year, and disease risk score. Using multivariable logistic regression, the associations between FRID exposure in the 90 days preceding falls and fall-related injuries that required emergency department or hospitalization were determined with adjusted odds ratios (aORs) and 95% confidence intervals (CIs).

RESULTS

Exposure to any FRID increased the risk of fall-related injury when compared with non-users in both HC (aOR, 1.34; 95% CI, 1.30-1.40) and LTC (aOR, 1.54; 95% CI, 1.46-1.63) populations. The increased odds of fall-related injuries were evident among most FRID categories, with the highest odds found with dopaminergic agents and antidepressants in both HC and LTC populations. The use of multiple FRIDs was associated with a greater odds of fall-related injury. Exposure to ≥5 FRIDs was associated with an almost twofold higher odds of fall-related injury in HC (aOR, 1.67; 95% CI, 1.57-1.77) and LTC (aOR, 1.92; 95% CI, 1.73-2.13) residents compared with non-users. The findings were similar across multiple subgroups and sensitivity analyses, with higher odds among new users compared with chronic users.

CONCLUSIONS AND IMPLICATIONS

Multiple categories of FRIDs are associated with an increased risk of fall-related injuries in older adults. Clinicians should minimize use of these medications wherever possible. Fall prevention initiatives should incorporate strategies to prioritize deprescription of the highest risk FRIDs.

Automated abdominal aortic calcification scoring from vertebral fracture assessment images and fall-associated hospitalisations: the Manitoba Bone Mineral Density Registry

Abdominal aortic calcification (AAC), a subclinical measure of cardiovascular disease (CVD) that can be assessed on vertebral fracture assessment (VFA) images during osteoporosis screening, is reported to be a falls risk factor. A limitation to incorporating AAC clinically is that its scoring requires trained experts and is time-consuming. We examined if our machine learning (ML) algorithm for AAC (ML-AAC24) is associated with a higher fall-associated hospitalisation risk in the Manitoba Bone Mineral Density (BMD) Registry. A total of 8565 individuals (94.0% female, age 75.7 ± 6.8 years) who had a BMD and VFA image from DXA between February 2010 and December 2017 were included. ML-AAC24 was categorised based on established categories (ML-AAC24 = low < 2; moderate 2 to < 6; high ≥ 6). Cox proportional hazards models assessed the relationship between ML-AAC24 categories and incident fall-associated hospitalisations obtained from linked health records (mean ± SD follow-up, 3.9 ± 2.2 years). Individuals with moderate (9.6%) and high ML-AAC24 (11.7%) had a greater proportion of fall-associated hospitalisations, compared to those with low ML-AAC24 (6.0%). In age and sex-adjusted models, compared to low ML-AAC24, moderate (HR 1.49, 95% CI 1.24-1.79) and high ML-AAC24 (HR 1.89, 95% CI 1.56-2.28) were associated with greater hazards for a fall-associated hospitalisation. Results were comparable (HR 1.37, 95% CI 1.13-1.65 and HR 1.60, 95% CI 1.31-1.95, respectively) after multivariable adjustment, including prior falls and CVD, as well as medication use. Integrating ML-AAC24 into bone density machine software to identify high risk individuals would opportunistically provide important information on fall and cardiovascular disease risk to clinicians for evaluation and intervention.

Higher-level gait disorders: a population-based study on prevalence, quality of life, depression and confidence in gait and balance

Background

Higher-level gait disorders (HLGDs) are slow, unsteady neurological GDs in older people. GDs can reduce quality of life (QoL) and cause depression. This has not been investigated in HLGD even though some HLGD causes are treatable, potentially affecting associated problems. We aimed to investigate gait and balance confidence, depressive symptoms and QoL in HLGD.

Methods

In a population (n=3769, 65-84y), 798 reported gait impairment (questionnaire) and were clinically examined together with 249 age- and sex-matched controls. Gait property groups were formed: 'HLGD', 'other neurological GD', 'non-neurological GD' or 'no GD'. Swedish Falls Efficacy Scale (FES(S)), Modified Gait Efficacy Scale (mGES), Euro Quality of Life 5-Dimension 5-Level index, Euro Quality of Life Visual Analogue Scale (EQ VAS) and Geriatric Depression Scale-15 (GDS-15) were compared.

Results

In the general population, 38% had GDs, of which 16% (n=87/561) were HLGDs, giving an HLGD prevalence of 5.8%; 26% (n=145/561) were other neurological GDs; and 59% (n=329/561) non-neurological GDs. HLGD had more depressive symptoms than non-neurological GD and no GD (GDS-15 HLGD, 3.9±3.4; non-neurological GD, 2.5±2.8; no GD, 1.4±2.0; p<0.05), lower EQ VAS (HLGD, 63±17; non-neurological GD, 71±18; no GD, 82±14; p<0.001), lower gait confidence (mGES HLGD, 60±22; non-neurological GD, 74±21; no GD, 90±13; p<0.001) and lower balance confidence (FES(S) HLGD, 93±32; non-neurological GD, 111±25; no GD, 124±13; p<0.001).

Conclusions

HLGDs are common and associated with reduced QoL, reduced confidence in gait and balance, and depressive symptoms, emphasising awareness of mental health among older people with slow unsteady gait.

Prevalence and risk factors of self-reported adverse drug events in elderly co-morbid patients in northeastern China: a cross-sectional study

BACKGROUND

Older adults are vulnerable to adverse drug events given the pharmacokinetic and pharmacodynamic changes that coming with ageing, as well as they often take multiple medications for their chronic health conditions, especially older co-morbidities. ADEs can cause unnecessary emergency department visits and hospitalization, which contribute to financial burden and decreased quality of life. This study aims to investigate the prevalence of adverse drug events in elderly co-morbid patients in Liaoning province and explore its risk factors, in order to ensure medication safety in elderly patients.

METHODS

This was a cross-sectional study that enrolled elderly patients with co-morbidities, and the data were collected by nurses using a structured interview method for elderly patients with multimorbidity. Risk factors for patient-reported adverse drug events were identified by univariate and logistic regression analyses.

RESULTS

A total of 329 elderly patients were enrolled, among whom 169 were females, with an age ranging from 61 to 90 years. 205 participants (62.3%) had 462 "possible-probable-certain" adverse drug events, and 156 (47.4%) experienced two or more self-reported adverse drug events concurrently. The logistic regression analysis included four variables: female (OR = 2.194, 95% confidence interval 1.281-3.760, P = 0.004), numbers of daily drugs > 12 (OR = 2.257, 95% confidence interval 1.254-4.061, P = 0.007), history of fall within 1 year (OR = 3.106, 95% confidence interval 1.112-8.674, P = 0.031), and medication noncompliance (OR = 3.768, 95% confidence interval 1.535-9.249, P = 0.004).

CONCLUSION

Patient-reported adverse drug events are more prevalent in older co-morbid patients in Liaoning province. Female, numbers of daily drugs, fall history with 1 year and poor medication compliance were significantly and independently associated with adverse drug events. These findings may provide informative interventions for the medication management in elderly patients living with multimorbidity.

Risk factors for falls in older people with pre-frailty: A systematic review and meta-analysis

BACKGROUND

Frailty is considered highly prevalent among the elderly, and falls are a severe adverse event that occurs at a significantly higher rate in frail elderly patients, leading to serious consequences. The pre-frailty stage represents a reversible transitional state between health and frailty, and targeted interventions for pre-frail older adults can effectively reduce the incidence of falls in this population. Existing studies have not definitely identified the risk factors for falls in pre-frail older adults. This paper explores the relevant risk factors for falls in pre-frail older adults.

METHODS

PubMed, Embase, Web of Science, Cochrane Library, CBM, CNKI, Wan fang, and VIP databases were searched for studies published from inception to 2023, without language restrictions. Observational studies were included in this systematic review that analyzed risk factors for accidental falls in pre-frail older adults. The NOS scale was used to evaluate the quality of cohort studies and case-control studies, while the AHRQ scale was used to evaluate the quality of the cross-sectional study. We utilized odds ratios (OR) and their corresponding 95 % confidence intervals (CI) to describe the statistical indicators. OR and 95 % CI values were directly extracted and organized in Excel. In cases where OR and CI values were not directly available, we extracted β and p values, calculated Exp using functions, and subsequently derived OR and 95 % CI using formulas. Finally, data pertaining to each risk factor were incorporated into RevMan 5.4 software for statistical analysis and effect size synthesis. We performed tests for heterogeneity and evaluated publication bias.

RESULTS

A total of 14,370 studies were initially identified, and 26 studies were included in the systematic review. Among these studies, 14 were of high quality, while the remaining 12 were of moderate quality. A total of 16 risk factors were identified as potential risk factors for falls in pre-frail older adults. Significant risk factors were peripheral neuropathy(OR = 3.18, 95 %CI:3.02-3.35), decreased gait speed(OR = 1.90, 95 %CI:1.60-2.27), decreased ability to perform activities of daily living(OR = 1.57, 95 % CI:1.42-1.75), grip strength decreases(OR = 1.53, 95 % CI:1.17-2.00), gender (female)(OR = 1.51, 95 % CI:1.39-1.64), pain(OR = 1.47, 95 %CI:1.41-1.54), history of falls(OR = 1.20, 95 %CI:1.13-1.28) and age(OR = 1.10, 95 %CI:1.07-1.14).

CONCLUSIONS

The occurrence of falls in pre-frail older adults is associated with multiple risk factors. These risk factors can provide clinical nursing staff with specific focal points for monitoring this population and devising targeted fall prevention measures, with the aim of reducing the incidence of falls in pre-frail older adults.

REGISTRATION

The systematic review was registered on the International Prospective Register of Systematic Review (CRD42023450670).

The association between falls and fall-risk-increasing drugs among older patients in out-patient clinics: A retrospective cohort, single center study

BACKGROUND

Falls among older adults are considered a significant global health concern, often leading to severe injuries and increased healthcare costs. Fall-risk-increasing drugs (FRIDs), such as opioids and benzodiazepines, have been identified as contributing factors, yet the causal relationship remains unclear. This study examined the association between FRIDs, identified using the STOPP version 2 and STOPP Fall criteria, and falls among older outpatients.

METHODS

This retrospective cohort study included 19,705 patients aged 65 and older who visited outpatient clinics at Thammasat University Hospital, Thailand, in 2021. Data were collected from electronic medical records, including demographics, public health insurance schemes, diagnoses, and prescribed medications. FRIDs were identified using section K of STOPP version 2 and STOPPFall criteria. The association between FRIDs and falls was analyzed using multiple logistic regression.

RESULTS

The prevalence of FRIDs was 33 %, with Lorazepam being the most common. The overall incidence of falls was 1.48 %. An adjusted relative risks (ARR) of falls in the participants with FRIDs was 1.35 (95 % CI: 1.03-1.76) and 1.31 (95 % CI: 1.03-1.66) according to STOPP version 2 and STOPPFall criteria, respectively. Females, patients over 70, and those with polypharmacy or frequent outpatient visits also had increased fall risks.

CONCLUSION

FRIDs are associated with an increased risk of falls among older adults in outpatient settings. These findings highlight the need for careful prescribing and monitoring of FRIDs, particularly in older patients with other fall risk factors.

Risk Factors for Falls Among Hospitalized Medical Patients - A Systematic Review and Meta-analysis

OBJECTIVE

To identify and quantify risk factors for in-hospital falls in medical patients.

DATA SOURCES

Six databases (MEDLINE, Embase, Cochrane Database of Systematic Reviews, Cochrane Central Register of Controlled Trials, CINAHL, and Google Scholar) were systematically screened until April 11, 2023, to identify relevant articles.

STUDY SELECTION

All titles and abstracts of the retrieved articles were independently screened by 2 researchers who also read the full texts of the remaining articles. Quantitative studies that assessed risk factors for falls among adult patients acutely hospitalized were included in the review. Publications that did not capture internal medicine patients or focused on other specific populations were excluded.

DATA EXTRACTION

Information on study characteristics and potential risk factors were systematically extracted. Risk of bias was assessed using the Quality in Prognosis Studies tool. Preferred Reporting Items for Systematic Reviews and Meta-Analyses and Meta-analyses of Observational Studies in Epidemiology guidelines were followed for reporting.

DATA SYNTHESIS

The main outcome was any in-hospital falls. Using a random-effects meta-analysis model, association measures for each risk factor reported in 5 or more studies were pooled. Separate analyses according to effect measure and studies adjusted for sex and age at least were performed. Of 5067 records retrieved, 119 original publications from 25 countries were included. In conclusion, 23 potential risk factors were meta-analyzed. Strong evidence with large effect sizes was found for a history of falls (odds ratio [OR], 2.54; 95% confidence interval [CI], 1.63-3.96; I2, 91%), antidepressants (pooled OR, 2.25; 95% CI, 1.92-2.65; I2, 0%), benzodiazepines (OR, 1.97; 95% CI, 1.68-2.31; I2, 0%), hypnotics-sedatives (OR, 1.90; 95% CI, 1.53-2.36; I2, 46%), and antipsychotics (OR, 1.61; 95% CI, 1.33-1.95; I2, 0%). Furthermore, evidence of associations with male sex (OR, 1.22, 95% CI, 0.99-1.50; I2, 65%) and age (OR, 1.17, 95% CI, 1.02-1.35; I2, 72%) were found, but effect sizes were small.

CONCLUSIONS

The comprehensive list of risk factors, which specifies the strength of evidence and effect sizes, could assist in the prioritization of preventive measures and interventions.

Sex-related differences in heart failure patients: physiological mechanisms of cardiovascular ageing and evidence-based sex-specific medical therapies

This review aims to describe the sex differences in heart failure (HF) patients, with a particular emphasis on the effect of cardiovascular ageing. Additionally, it takes into consideration the sex-related variation in cardiovascular health and physiology and the role ageing plays in HF and its implications in drug therapy. The pharmacokinetics and pharmacodynamics of the common HF medications, classified according to the established sub-types, are summarised with respect to sex-specific documented findings. Despite numerous studies confirming significant differences in HF outcomes according to sex, there are no current guidelines that consider patients' sex in medical therapy of HF. Moreover, females are significantly under-represented in research trials, as well as under-treated in clinical practice, which hinders our understanding of HF in this demographic. Most of the current knowledge on sex-specific HF therapies is driven by secondary analyses of studies not primarily undertaking sex-specific analyses. Therefore, we propose a multi-faceted approach, including increased awareness among healthcare providers and more inclusive research to create a personalised care plan accounting for sex differences in HF management. Given the highlighted knowledge gaps, it is paramount for new research efforts to account for the different sex phenotypes in HF.

Multilevel factors influencing falls of older patients in hospital: The risk of hospital-induced delirium and the impact of nurse staffing

OBJECTIVE

This study aimed to explore the individual and organizational factors influencing falls among older inpatients, with a particular focus on the risk posed by hospital-induced delirium and the effect of nurse staffing levels.

METHODS

This retrospective cohort study utilized data from a national healthcare database to examine falls in hospitalized older adults, applying a mixed-effect logistic regression model RESULTS: Data from 391,902 patients across 580 hospitals revealed that 1.2 % of older inpatients experienced falls. Influential factors for falls included advanced age, the use of multiple medications and treatments, impaired mobility, and hospital-induced delirium. Nurse staffing levels markedly influenced the reduction of fall risks among older patients.

CONCLUSION

Falls among hospitalized older adults are a frequent consequence of multifaceted risk components, highlighting the need for comprehensive fall prevention strategies and adequate.

Sex differences of fall-risk-increasing drugs in the middle-aged and elderly: a descriptive, cross-sectional study of FDA adverse event reporting system

It's well known that sex is a risk factor for the occurrence of adverse events (AEs), most of which have found sex differences. Real-world data studies on the sex differences of fall-risk-increasing drugs (FRIDs) are few and far between, with most small-scale retrospective studies based on FRID classes. To establish a list of FRIDs and describe their sex differences, we used preferred terms from the Medical Dictionary for Regulatory Activities to search for AEs in the FDA Adverse Event Reporting System (FAERS), and then perform disproportionality analyses and female/male ratio analyses. During January 2004 to March 2023, 101,746 fall-related AEs were reported in FAERS from patients aged 50 to 100, with 68,492 (67.3%) females and 32,547 (32.0%) males. We found 261 signals for females while 284 for males. For females, the top 3 signals with the highest reporting odds ratio (ROR) were anethole trithione, clopenthixol, nikethamide (ROR: 388.88, 212.10, 113.94), while the top 3 signals with the highest lower limit of information component (IC025) were nikethamide, anethole trithione, benzbromarone (IC025: 3.91, 3.15, 2.49). For males, the top 3 signals with the highest ROR were fluprednidene acetate, potassium hydroxide, ketazolam (ROR: 216.86, 108.43, 108.43), while the top 3 signals with the highest IC025 were clomethiazole, piribedil, melperone (IC025: 3.31, 3.24, 2.99). Moreover, among the 119 shared signals found between males and females, 33 were positively correlated with falls in females and 38 with falls in males. Signals showing significant sex differences were mainly concentrated on agents of the immune, nervous, musculo-skeletal, and cardiovascular systems. We offered a series of FRIDs and suggested their sex differences in falls through the FAERS. In the future, it is essential to balance the inclusion of women and men, and analyse sex-stratified for FRIDs.

Association of fall risk-increasing drugs with falls in generally healthy older adults: a 3-year prospective observational study of the DO-HEALTH trial

BACKGROUND

The association between fall risk-increasing drugs (FRIDs, medications known to be associated with falls) and the number of falls among generally healthy and active community-dwelling older adults is understudied. Prior studies have focused on individual medication classes or have predominantly relied on retrospective assessments of falls. The aim of this study was to investigate the association between FRID use at baseline and the prospective incidence rates of total, injurious and recurrent falls in community-dwelling older adults.

METHODS

This is a 3-year observational analysis of DO-HEALTH, a randomized controlled trial, among community-dwelling adults aged ≥ 70 years without major diseases at baseline. The main exposures were use of at least one FRID and multiple FRIDs (≥ 2 FRIDs) at baseline. The number of total falls (including high- and low-trauma falls, as well as injurious falls) over 3 years of follow-up was defined as the primary outcome, and the number of injurious and the number of recurrent total falls (≥ 2 falls), as the two separate secondary outcomes. To examine these associations, separate negative binomial regression models controlled for the fixed effects of treatment allocation in the DO-HEALTH trial, study site, fall in the last year, age, sex, BMI, and walking aid were used. Additionally, an offset of the logarithm of each participant's time in the study was included in the models.

RESULTS

A total of 2157 participants were included, with a baseline median age of 74.0 years, 61.7% of whom were women, and 41.9% having experienced a prior fall in the year preceding enrolment. At baseline, 908 (42.1%) participants used at least one FRID, and 351 (16.3%) reported multiple FRIDs use. Prospectively, over 3 years of follow-up, 3333 falls were reported by 1311 (60.8%) out of the 2157 participants. Baseline use of at least one FRID was significantly associated with increased incidence rates of total falls (incidence rate ratio (IRR) [95% Confidence Interval (CI)] = 1.13 [1.01-1.27]), injurious falls (IRR = 1.15 [1.02-1.29]), and recurrent falls (IRR = 1.12 [1.01-1.23]) over 3 years. These associations were most pronounced among users of multiple FRIDs, with increased incidence rates of total falls (IRR = 1.22 [1.05-1.42]), injurious falls (IRR = 1.33 [1.14-1.54]) and recurrent falls (IRR = 1.14 [1.02-1.29]).

CONCLUSION

Our results suggest that FRID use is associated with increased prospective incidence rates of total, injurious, and recurrent falls even among generally healthy older adults.

Individual Pharmacotherapy Management (IPM-II) for Patient and Drug Safety in Polypharmacy via Clinical Electronic Health Record Is Associated with Significant Fall Prevention

BACKGROUND/OBJECTIVES

Falls and fractures are emerging as a near-pandemic and major global health concern, placing an enormous burden on ageing patients and public health economies. Despite the high risk of polypharmacy in the elderly patients, falls are usually attributed to age-related changes. For the "Individual Pharmacotherapy Management (IPM)" established at the University Hospital Halle, the IPM medication adjustments and their association with in-hospital fall prevention were analysed.

METHODS

On the basis of the most updated digital overall patient view via his inpatient electronic health record (EHR), IPM adapts each drug's Summary of Product Characteristics to the patient's condition. A retrospective pre-post intervention study in geriatric traumatology on ≥70 years old patients compared 200 patients before IPM implementation (CG) with 204 patients from the IPM intervention period (IG) for the entire medication list, organ, cardiovascular and vital functions and fall risk parameters.

RESULTS

Statistically similar baseline data allowed a comparison of the average 80-year-old patient with a mean of 11.1 ± 4.9 (CG) versus 10.4 ± 3.6 (IG) medications. The IPM adjusted for drug-drug interactions, drug-disease interactions, overdoses, anticholinergic burden, adverse drug reactions, esp. from opioids inducing increased intrasynaptic serotonin, psychotropic drugs, benzodiazepines, contraindications and missing prescriptions. IPM was associated with a significant reduction in in-hospital falls from 18 (9%) in CG to 3 (1.5%) in IG, a number needed to treat of 14, relative risk reduction 83%, OR 0.17 [95% CI 0.04; 0.76], p = 0.021 in multivariable regression analysis. Factors associated with falls were antipsychotics, digitoxin, corticosteroids, Würzburg pain drip (combination of tramadol, metamizole, metoclopramide), head injury, cognitive impairment and aspects of the Huhn Fall Risk Scale including urinary catheter.

CONCLUSION

The results indicate medication risks constitute a major iatrogenic cause of falls in this population and support the use of EHR-based IPM in standard care for the prevention of falls in the elderly and for patient and drug safety. In terms of global efforts, IPM contributes to the running WHO and United Nations Decade of Healthy Ageing (2021-2030).

Dealing with adverse drug reactions in the context of polypharmacy using regression models

Polypharmacy in older adults increases the risk of adverse drug reactions (ADRs), but studying this relationship is complex. In real-world data, the high number of medications, coupled with rare drug combinations, results in high-dimensional datasets that are difficult to analyze using conventional statistical methods. This study applies horseshoe and lasso regression for analyzing rare events in polypharmacy contexts, focusing on severe ADRs such as falls and bleedings. These regression models are executed on a multi-center dataset compiling 7175 cases from the ADRED project to detect potential ADR-associated drugs among 100 most common drugs in emergency department admissions. Positive predictors are classified by using 50% and 90% credibility intervals. This study demonstrates that regression models with horseshoe or lasso priors are effective for analyzing ADRs, providing a comprehensive consideration of multiple factors in large, sparse datasets and improving signal detection in polypharmacy, addressing a significant challenge in pharmacovigilance. Both priors yielded consistent and clinically meaningful results. The horseshoe regression resulted in fewer potential positive predictors overall, which could make it suitable as a diagnostic tool. While these regressions generate valuable information, there are still challenges in setting appropriate thresholds for determining and interpreting the positive results.

Association of diuretics with falls and wrist fractures: a Mendelian randomization study

Background

The association between diuretics and falls in older adult has been reported in previous studies, but discrepancy remains between the different types of diuretics. The association of diuretics with the risk of wrist fractures due to diuretics is also unclear. Therefore, in this study, we determined the association of diuretics with falls and wrist fractures by Mendelian randomization.

Methods

We used a two-sample Mendelian randomization (MR) approach to evaluate the effects of the loop diuretics\potassium-sparing diuretics\thiazide diuretics (LDs\PSDs\TDs) on the risk of falls and wrist fracture using the three diuretic-associated genetically-predicted single nucleotide polymorphisms (SNPs) as genetic tools. The inverse variance weighting (IVW) method was used as the main evaluation method, with odds ratio (OR) as the evaluation criterion. Additionally, weighted median (WME), MR-Egger, weighted mode (WM) and simple mode (SM) methods were used together for the MR analysis, and sensitivity analyses were performed to assess the robustness of the main results.

Result

A total of 35 SNPs were included in this study as instrumental variables to replace LDs, PSDs, and TDs, which were 24, 7, and 4. Genetic substitutions for diuretics associated with increased risk of falls were LDs (OR = 1.012043, 95%CI: 1.001607-1.022588, p = 0.022337), PSDs (OR = 1.023794, 95%CI: 1.005605-1.042312, p = 0.010138). Genetically proxied TDs showed no association with falls, but the use of TDs showed a negative correlation with the incidence of wrist fracture (OR = 0.833, 95%CI: 0.767-0.905, p < 0.001). The Cochran Q-test showed no heterogeneity and MR-PRESSO method excluded data pleiotropy.

Conclusion

Our findings suggest that the use of loop diuretics (LDs) or potassium-sparing diuretics (PSDs) increases the incidence of falls, but there is no causal relationship between thiazide diuretics (TDs) and falls, and TDs may actually reduce the risk of wrist fractures. Clinical use of diuretics necessitates vigilance and appropriate preventive measures to minimize fall-related events.

Detection of ethanol, cannabinoids, benzodiazepines, and opioids in older adults evaluated for serious injuries from falls

BACKGROUND

In 2020, there were 36.7 million reported falls among older adults (65+) in the United States. Ethanol and other sedating substances may increase fall risk among older adults due to their effect on cognitive and physical function. We estimate the prevalence of these substances in blood specimens of older adults presenting with a fall injury at selected trauma centers.

METHODS

The initial study collected blood specimens from May 2020 through July 2021 from adults undergoing a trauma team evaluation at selected United States Level 1 trauma centers. We limited our study to older adults evaluated after a fall (n = 1,365) and selected a random sample (n = 300) based on age, sex, and trauma-center quotas. Medical health records and blood specimens obtained at trauma center presentation were analyzed. We estimated the prevalence of ethanol, benzodiazepines, cannabinoids, and opioids in the blood specimens. Two-sample tests of binomial proportions and Chi-square two-tailed tests were used to compare prevalence estimates of substances by demographic characteristics.

RESULTS

At least one substance was detected among 31.3% of samples analyzed. Prevalences of specific substances detected were 9.3% (95% CI: 6.0-12.6%) for benzodiazepines, 4.3% (95% CI: 2.0-6.7%) for cannabinoids, 8.0% (95% CI: 5.2-11.7%) for ethanol, and 15.0% (95% CI: 10.9-19.1%) for opioids. There were 18 deaths (6%; 95% CI: 3.6-9.3%). One-third of decedents had at least one substance detected in their blood.

DISCUSSION

Opioids were the most frequently detected substance, followed by benzodiazepines, ethanol, and cannabinoids. Substance use prevalence was not uniform across demographics, with differences observed by sex and age.

CONCLUSIONS

This study provides insight into the frequency of the presence of substances that may contribute to fall risk and serious injury among older adults. Screening older adults for substances that impair cognitive and physical function can enhance clinical fall prevention efforts.

High rate of potentially inappropriate medication use in older people: a case-control study

Annually, 172 million fall events cause temporary or permanent impairment in older adults, and this number is increasing. Contributing factors that increase the risk for falls include age, polypharmacy, and malnutrition. This study evaluated medications mainly included in the EU(7)-PIM (potentially inappropriate medication) list. From March 21, 2022, to July 6, 2022, 945 patients who experienced a fall and visited the Department of Emergency Medicine at the Albert Szent-Györgyi Health Centre of the University of Szeged in Hungary. Data from 886 patients were collected (study group). The control group included 1364 patient data collected from three general practice in Hungary. The use of ≥ 2 EU(7)-PIM drugs was found to be associated with increased risk for falls (adjusted odds ratio [AOR], 1.38; 95% confidence interval [CI] 1.01-1.88). Piracetam (AOR, 1.81; 95% CI, 1.28-2.57) and trimetazidine (AOR, 1.62; 95% CI, 1.17-2.24) were associated with increased risk for falls. Doxazosin was associated with a low risk for falls (AOR, 0.59; 95% CI, 0.41-0.86). Tiapride (AOR, 3.54; 95% CI, 1.75-7.17), gliclazide (AOR, 1.57; 95% CI, 1.02-2.43), and vinpocetine (AOR, 1.95; 95% CI, 1.29-2.95) are not included in the EU(7)-PIM list; however, they are associated with increased risk for falls. Long-acting benzodiazepines (AOR, 1.79; 95% CI, 1.20-2.68), antidepressants (AOR, 1.89; 95% 95% CI, 1.37-2.61), serotonin-norepinephrine reuptake inhibitor (AOR, 2.82; 95% CI, 1.41-5.67; p < 0.01), and selective serotonin reuptake inhibitor (AOR, 1.88; 95% CI, 1.24-2.85) were also associated with increased risk for falls. However, Z-drugs were associated with a low risk for falls (AOR, 0.57; 95% CI, 0.36-0.92). With the help of this tool, trimetazidine and piracetam are filtered as EU(7)-PIM drugs associated with increased risk for falls.

Development of the ADFICE_IT clinical decision support system to assist deprescribing of fall-risk increasing drugs: A user-centered design approach

INTRODUCTION

Deprescribing fall-risk increasing drugs (FRIDs) is promising for reducing the risk of falling in older adults. Applying appropriate deprescribing in practice can be difficult due to the outcome uncertainties associated with stopping FRIDs. The ADFICE_IT intervention addresses this complexity with a clinical decision support system (CDSS) that facilitates optimum deprescribing of FRIDs by using a fall-risk prediction model, aggregation of deprescribing guidelines, and joint medication management.

METHODS

The development process of the CDSS is described in this paper. Development followed a user-centered design approach in which users and experts were involved throughout each phase. In phase I, a prototype of the CDSS was developed which involved a literature and systematic review, European survey (n = 581), and semi-structured interviews with clinicians (n = 19), as well as the aggregation and testing of deprescribing guidelines and the development of the fall-risk prediction model. In phase II, the feasibility of the CDSS was tested by means of two usability testing rounds with users (n = 11).

RESULTS

The final CDSS consists of five web pages. A connection between the Electronic Health Record allows for the retrieval of patient data into the CDSS. Key design requirements for the CDSS include easy-to-use features for fast-paced clinical environments, actionable deprescribing recommendations, information transparency, and visualization of the patient's fall-risk estimation. Key elements for the software include a modular architecture, open source, and good security.

CONCLUSION

The ADFICE_IT CDSS supports physicians in deprescribing FRIDs optimally to prevent falls in older patients. Due to continuous user and expert involvement, each new feedback round led to an improved version of the system. Currently, a cluster-randomized controlled trial with process evaluation at hospitals in the Netherlands is being conducted to test the effect of the CDSS on falls. The trial is registered with ClinicalTrials.gov (date; 7-7-2022, identifier: NCT05449470).

Identification of medication-related fall risk in adults and older adults admitted to hospital: A machine learning approach

The study aimed to develop and validate, through machine learning, a fall risk prediction model related to prescribed medications specific to adults and older adults admitted to hospital. A case-control study was carried out in a tertiary hospital, involving 9,037 adults and older adults admitted to hospital in 2016. The variables were analyzed using the algorithms: logistic regression, naive bayes, random forest and gradient boosting. The best model presented an area under the curve = 0.628 in the older adult subgroup, compared to an area under the curve (AUC) = 0.776 in the adult subgroup. A specific model was developed for this sample. The gradient boosting model presented the best performance in the sample of older adults (AUC = 0.71). Models developed to predict the risk of falls based on medications specifically aimed at older adults presented better performance in relation to models developed in the total population studied.

Polypharmacy and potentially inappropriate medications in older adults who use long-term care services: a cross-sectional study

BACKGROUND

Older adults requiring care often have multiple morbidities that lead to polypharmacy, including the use of potentially inappropriate medications (PIMs), leading to increased medical costs and adverse drug effects. We conducted a cross-sectional study to clarify the actual state of drug prescriptions and the background of polypharmacy and PIMs.

METHODS

Using long-term care (LTC) and medical insurance claims data in the Ibaraki Prefecture from April 2018 to March 2019, we included individuals aged ≥ 65 who used LTC services. The number of drugs prescribed for ≥ 14 days and the number of PIMs were counted. A generalized linear model was used to analyze the association between the backgrounds of individuals and the number of drugs; logistic regression analysis was used for the presence of PIMs. PIMs were defined by STOPP-J and Beers Criteria.

RESULTS

Herein, 67,531 older adults who received LTC services were included. The median number of total prescribed medications and PIMs was 7(IQR 5-9) and 1(IQR 0-1), respectively. The main PIMs were loop diuretics/aldosterone antagonists (STOPP-J), long-term use of proton pump inhibitors (Beers Criteria), benzodiazepines/similar hypnotics (STOPP-J and Beers Criteria), and nonsteroidal anti-inflammatory drugs (STOPP-J and Beers Criteria). Multivariate analysis revealed that the number of medications and presence of PIMs were significantly higher in patients with comorbidities and in those visiting multiple medical institutions. However, patients requiring care level ≥1, nursing home residents, users of short-stay service, and senior daycare were negatively associated with polypharmacy and PIMs.

CONCLUSIONS

Polypharmacy and PIMs are frequently observed in older adults who require LTC. This was prominent among individuals with comorbidities and at multiple consulting institutions. Utilization of nursing care facilities may contribute to reducing polypharmacy and PIMs.

Drug burden index in people living with HIV over 50 years of age in a real clinical practice cohort

OBJECTIVES

To determine DBI and its relationship with polypharmacy and pharmacotherapeutic complexity (PC) in a cohort of PLWH over 50 years of age at follow-up of pharmacotherapy in a tertiary hospital.

METHODS

Observational and retrospective study that included PLWH in active antiretroviral treatment over 50 years of age who have been followed up in outpatient pharmacy services. Pharmacotherapeutic complexity was estimated through Medication Regimen Complexity Index (MRCI). Collected variables included comorbidities, current prescriptions and its classification according to anticholinergic and sedative activity and associated risk of falls.

RESULTS

Studied population included 251 patients (85.7% men; median age: 58 years, interquartile range: 54-61). There was a high prevalence of high DBI scores (49.2%). High DBI was significantly correlated with a high PC, polypharmacy, psychiatric comorbidity and substances abuse (p<0.05). Among sedative drugs, the most prescribed were anxiolytic drugs (N05B) (n=85), antidepressant drugs (N06A) (n=41) and antiepileptic drugs (N03A) (n=29). For anticholinergic drugs, alpha-adrenergic antagonist drugs (G04C) were the most prescribed (n=18). Most frequent drugs associated with risk of falls were anxiolytics (N05B) (n=85), angiotensin-converting enzyme inhibitors (C09A) (n=61) and antidepressants (N06A) (n=41).

CONCLUSION

The DBI score in older PLWH is high and it is related to PC, polypharmacy, mental diseases and substance abuse as is the prevalence of fall-related drugs. Control of these parameters as well as the reduction of the sedative and anticholinergic load should be included in the lines of work in the pharmaceutical care of people living with HIV+.

A Longitudinal Study of the Use and Effects of Fall-Risk-Increasing Drugs in Residential Aged Care

OBJECTIVES

Fall-risk-increasing drugs (FRIDs)-psychotropics and cardiovascular disease (CVD) drugs-may elevate the risk of falling, with strong evidence observed in psychotropic FRIDs, whereas findings from cardiovascular disease (CVD) FRIDs remain inconclusive. Existing studies on FRIDs and falls are often hampered by methodologic limitations. Leveraging longitudinal observational data, we aimed to determine the long-term patterns of FRID use and their association with falls in residential aged care (RAC) homes.

DESIGN

A retrospective longitudinal cohort study.

SETTING AND PARTICIPANTS

A total of 4207 permanent residents newly admitted to 27 RAC homes in Sydney, Australia.

METHOD

The outcomes were incidence of all and injurious falls. We measured exposure to each FRID over 60 months using the Proportion of Days Covered (PDC) metric. We used group-based multitrajectory modeling to determine concurrent usage patterns of psychotropics and CVD FRIDs and applied negative binomial regression to assess their associations with the outcomes.

RESULTS

A total of 83.6% (n = 3516) and 77.3% (n = 3254) residents used psychotropic and CVD FRIDs, respectively. The PDC values ranged from 67.3% (opioids) to 86.9% (antidepressants) for specific psychotropics and 79.0% (α-adrenoceptor antagonists) to 89.6% (β blockers) for CVD FRIDs. We identified 4 groups: group 1, low psychotropics-low CVDs use (16.7%, n = 701); group 2, low psychotropics-high CVDs (25.0%, n = 1054); group 3, high psychotropics-high CVDs (41.0%, n = 1723); and group 4, high psychotropics-low CVDs (17.3%, n = 729). Group 4 had a significantly higher rate of falls than the other groups for both outcomes, including relative to group 3, in which exposure to both FRID classes was high.

CONCLUSIONS AND IMPLICATIONS

Our findings reveal concerningly high FRID use in RAC homes and highlight a critical difference in the impact of the 2 major FRID classes on falls. Psychotropics were strongly associated with falls, whereas the studied CVD FRIDs did not elevate risk of falling.

A quantitative study on the impact of a community falls pharmacist role, on medicines optimisation in older people at risk of falls

BACKGROUND

The World Falls guidance includes medication review as part of its recommended multifactorial risk assessment for those at high risk of falling. Use of Falls Risk Increasing Drugs (FRIDs) along with polypharmacy and anticholinergic burden (ACB) are known to increase the risk of falls in older people.

METHOD

The impact of a community falls pharmacist within a hospital Trust, working as part of a multi-professional community falls prevention service, was evaluated in 92 people aged 65 years or older, by analysing data before and after pharmacist review, namely: number and type of FRIDs prescribed; anticholinergic burden score using ACBcalc®; appropriateness of medicines prescribed; bone health review using an approved too; significance of clinical intervention; cost avoidance, drug cost savings and environmental impact.

RESULTS

Following pharmacist review, there was a reduction in polypharmacy (mean number of medicines prescribed per patient reduced by 8%; p < 0.05) and anticholinergic burden score (average score per patient reduced by 33%; p < 0.05). Medicines appropriateness improved (Medicines Appropriateness Index score decreased by 56%; p < 0.05). There were 317 clinically significant interventions by the community falls pharmacist. One hundred and one FRIDs were deprescribed. Annual cost avoidance and drug cost savings were £40,689-£82,642 and avoidable carbon dioxide (CO2) emissions from reducing inappropriate prescribing amounted to 941 kg CO2.

CONCLUSION

The community falls pharmacist role increases prescribing appropriateness in the older population at risk of falls, and is an effective and cost-efficient means to optimise medicines in this population, as well as having a positive impact on the environment.

A systematic review of fall prediction models for community-dwelling older adults: comparison between models based on research cohorts and models based on routinely collected data

BACKGROUND

Prediction models can identify fall-prone individuals. Prediction models can be based on either data from research cohorts (cohort-based) or routinely collected data (RCD-based). We review and compare cohort-based and RCD-based studies describing the development and/or validation of fall prediction models for community-dwelling older adults.

METHODS

Medline and Embase were searched via Ovid until January 2023. We included studies describing the development or validation of multivariable prediction models of falls in older adults (60+). Both risk of bias and reporting quality were assessed using the PROBAST and TRIPOD, respectively.

RESULTS

We included and reviewed 28 relevant studies, describing 30 prediction models (23 cohort-based and 7 RCD-based), and external validation of two existing models (one cohort-based and one RCD-based). The median sample sizes for cohort-based and RCD-based studies were 1365 [interquartile range (IQR) 426-2766] versus 90 441 (IQR 56 442-128 157), and the ranges of fall rates were 5.4% to 60.4% versus 1.6% to 13.1%, respectively. Discrimination performance was comparable between cohort-based and RCD-based models, with the respective area under the receiver operating characteristic curves ranging from 0.65 to 0.88 versus 0.71 to 0.81. The median number of predictors in cohort-based final models was 6 (IQR 5-11); for RCD-based models, it was 16 (IQR 11-26). All but one cohort-based model had high bias risks, primarily due to deficiencies in statistical analysis and outcome determination.

CONCLUSIONS

Cohort-based models to predict falls in older adults in the community are plentiful. RCD-based models are yet in their infancy but provide comparable predictive performance with no additional data collection efforts. Future studies should focus on methodological and reporting quality.

Statin use and fall risk in adults: a cross-sectional survey and mendelian randomization analysis

BACKGROUND AND OBJECTIVE

The issue of falls poses a significant threat to the health of the elderly population. Although statins can cause myopathy, which implies that they may cause balance problems and increase the risk of falling, this has not been tested. Our objective was to assess whether the use of statins is linked to a higher risk of falls.

METHODS

A cross-sectional survey study and Mendelian randomization (MR) study were conducted to examine whether the use of statins was associated with an increased risk of falling and balance problems. The cross-sectional study included 2,656 participants from the US population (NHANES) who reported information on balance and falling problems in the past year and their use of statins. Univariate and multivariate logistic regression models were used to investigate the association between statin use and the likelihood of falling or experiencing balance problems. The MR study identified five Single Nucleotide Polymorphisms (SNPs) that predict statin use across five ancestry groups: Admixed African or African, East Asian, European, Hispanic, and South Asian. Additionally, SNPs predicting the risk of falls were acquired from the UK Biobank population. A two-sample MR analysis was performed to examine whether genetically predicted statin use increased the risk of falls.

RESULTS

The use of statins was found to be associated with an increased likelihood of balance and falling problems (balance problem, OR 1.25, 95%CI 1.02 to 1.55; falling problem, OR 1.27, 95%CI 1.03-1.27). Subgroup analysis revealed that patients under the age of 65 were more susceptible to these issues when taking statins (balance problem, OR 3.42, 95%CI 1.40 to 9.30; falling problem, OR 5.58, 95%CI 2.04-15.40). The MR analysis indicated that the use of statins, as genetically proxied, resulted in an increased risk of falling problems (OR 1.21, 95% CI 1.1-1.33).

CONCLUSION

Our study found an association between the use of statins and an increased risk of balance problems and falls in adults over 40 years old, and the MR study result suggested statin use increased risk of falls. The risk was higher in participants under 65 years old compared to those over 65 years old.

Assessing the Efficacy of the ARMOR Tool-Based Deprescribing Intervention for Fall Risk Reduction in Older Patients Taking Fall Risk-Increasing Drugs (DeFRID Trial): Protocol for a Randomized Controlled Trial

BACKGROUND

Falls in older patients can lead to serious health complications and increased health care costs. Fall risk-increasing drugs (FRIDs) are a group of drugs that may induce falls or increase the tendency to fall (ie, fall risk). Deprescribing is the process of withdrawal from an inappropriate medication, supervised by a health care professional, with the goal of managing polypharmacy and improving outcomes.

OBJECTIVE

This study aims to assess the effectiveness of a deprescribing intervention based on the Assess, Review, Minimize, Optimize, and Reassess (ARMOR) tool in reducing the risk of falls in older patients and evaluate the cost-effectiveness of deprescribing FRIDs.

METHODS

This is an open-label, parallel-group randomized controlled academic trial. Individuals aged 60-80 years who are currently taking 5 or more prescribed drugs, including at least 1 FRID, will be recruited. Demographic data, medical conditions, medication lists, orthostatic hypotension, and fall history details will be collected. Fall concern will be assessed using the Fall Efficacy Scale, and fall risk will be assessed by the Timed Up and Go test and Tinetti Performance-Oriented Mobility Assessment tool. In this study, all treating physicians will be randomized using a stratified randomization method based on seniority. Randomized physicians will do deprescribing with the ARMOR tool for patients on FRIDs. Participants will maintain diaries, and monthly phone follow-ups will be undertaken to monitor falls and adverse events. Physical assessments will be performed to evaluate fall risk every 3 months for a year. The rationality of prescription drugs will be evaluated using the World Health Organization's core indicators.

RESULTS

The study received a grant from the Indian Council of Medical Research-Safe and Rational Use of Medicine in October 2023. The study is scheduled to commence in April 2024 and conclude by 2026. Efficacy will be measured by fall frequency and changes in fall risk scores. Cost-effectiveness analysis will also include the incremental cost-effectiveness ratio calculation. Adverse events related to deprescription will be recorded.

CONCLUSIONS

This trial will provide essential insights into the efficacy of the ARMOR tool in reducing falls among the geriatric population who are taking FRIDs. Additionally, it will provide valuable information on the cost-effectiveness of deprescribing practices, offering significant implications for improving the well-being of older patients and optimizing health care resource allocation. The findings from this study will be pertinent for health care professionals, policy makers, and researchers focused on geriatric care and fall prevention strategies.

A European survey of older peoples' preferences, and perceived barriers and facilitators to inform development of a medication-related fall-prevention patient portal

PURPOSE

Falls are a major and growing health care problem in older adults. A patient portal has the potential to provide older adults with fall-prevention advice to reduce fall-risk. However, to date, the needs and preferences regarding a patient portal in older people who have experienced falls have not been explored. This study assesses content preferences, potential barriers and facilitators with regard to using a patient portal, as perceived by older people who have experienced falls, and explores regional differences between European participants.

METHODS

We conducted a survey of older adults attending an outpatient clinic due to a fall or fall-related injury, to explore their content preferences, perceived barriers, and facilitators with respect to a fall-prevention patient portal. Older adults (N = 121, 69.4% female, mean age: 77.9) were recruited from seven European countries.

RESULTS

Almost two-thirds of respondents indicated they would use a fall-prevention patient portal. The portal would preferably include information on Fall-Risk-Increasing Drugs (FRIDs), and ways to manage other related/relevant medical conditions. Facilitators included a user-friendly portal, with easily accessible information and physician recommendations to use the portal. The most-commonly-selected barriers were privacy issues and usage fees. A family member's recommendation to use the portal was seemingly more important for Southern and Eastern European participants compared to the other regions.

CONCLUSION

The majority of older people with lived falls experience expressed an interest in a fall-prevention patient portal providing personalized treatment advice to prevent further falls. The results will be used to inform the development of a fall-prevention patient portal. The fall-prevention patient portal is intended to be used in addition to a consultation with a physician. Future research is needed to explore how to prevent falls in older patients who are not interested in a fall-prevention patient portal.

Polypharmacy and Bleeding Outcomes After Percutaneous Coronary Intervention

BACKGROUND

Polypharmacy was reported to be associated with major bleeding in various populations. However, there are no data on polypharmacy and its association with bleeding in patients undergoing percutaneous coronary intervention (PCI).

METHODS AND RESULTS

Among 12,291 patients in the CREDO-Kyoto PCI Registry Cohort-3, we evaluated the number of medications at discharge and compared major bleeding, defined as Bleeding Academic Research Consortium Type 3 or 5 bleeding, across tertiles (T1-3) of the number of medications. The median number of medications was 6, and 88.0% of patients were on ≥5 medications. The cumulative 5-year incidence of major bleeding increased incrementally with increasing number of medications (T1 [≤5 medications] 12.5%, T2 [6-7] 16.5%, and T3 [≥8] 20.4%; log-rank P<0.001). After adjusting for confounders, the risks for major bleeding of T2 (hazard ratio [HR] 1.21; 95% confidence interval [CI] 1.08-1.36; P=0.001) and T3 (HR 1.27; 95% CI 1.12-1.45; P<0.001) relative to T1 remained significant. The adjusted risks of T2 and T3 relative to T1 were not significant for a composite of myocardial infarction or ischemic stroke (HR 0.95 [95% CI 0.83-1.09; P=0.47] and HR 1.06 [95% CI 0.91-1.23; P=0.48], respectively).

CONCLUSIONS

In a real-world population of patients undergoing PCI, approximately 90% were on ≥5 medications. Increasing number of medications was associated with a higher adjusted risk for major bleeding, but not ischemic events.

Factors Impacting Fall Severity in Hospitalized Patients: A Retrospective Cohort Study

Objectives: This retrospective case-controlled study aimed to evaluate the association between the severity of fall-related injuries and fall-risk-increasing drugs (FRIDs) in hospitalized patients. Methods: Data were collected from Changhua Christian Hospital, Taiwan, of all adult inpatients who experienced falls between January 2017 and December 2021, and were divided into two groups based on whether they sustained severe fall-related injuries. Retrospective data that may affect the severity of fall-related injuries and the use of FRIDs were investigated. Results: Among 1231 documented cases of falls, 26 patients sustained severe fall-related injuries. Older patients and those with osteoporosis were more susceptible to more severe injuries from a fall. The use of mobility aids and osteoporosis medications showed protective effects against fall injuries. No significant association was observed between fall-related injuries and comorbidities or FRIDs. Multivariate analysis confirmed the inverse correlation between the use of mobility aids, osteoporosis medications, and fall severity. Patients with osteoporosis exhibited significantly higher odds of sustaining more severe injuries with a fall (odds ratio = 3.02, 95% confidence interval: 1.21-7.53). Conclusions: This study highlights the importance of addressing risk factors associated with fall severity among hospitalized patients. Providing mobility aids to persons at greater risk.

Factors affecting outcomes among older trauma patients in Singapore: A retrospective observational study

Singapore faces a rapidly ageing population with its median age projected to be above 45 years by 2030. Our greying demographics is accompanied by a rise in chronic diseases and medication use, including polypharmacy. Longer life expectancy and increased activity levels have contributed to higher incidence of geriatric trauma locally, with a three-fold rise between 2004 and 2015. Older patients are at greater risk of poorer outcomes following trauma.3 However, the impact of comorbidities and medication use on post-trauma outcomes in Singapore’s ageing population remains unclear.

The effect of statins on falls and physical activity in people aged 65 and older: A systematic review

PURPOSE

Statins are commonly prescribed medications with recognised side effects including muscle weakness. Despite this, little is known about their effect on the physical activity and falls risk in the older population. This paper aims to explore the relationship between statin use and the physical activity and falls risk in adults aged 65 and older.

METHODS

MEDLINE, Embase, CINAHL and PsycINFO were searched on 21/11/2022 to obtain relevant articles. Data considered appropriate included that relating to muscle strength, grip strength, gait speed, balance and falls incidence. Reference and citation searches were performed to identify further relevant papers, and all eligible articles were subject to a Critical Appraisal Skills Programme (CASP) to assess potential bias. With the data being highly heterogeneous, no attempt to measure effect size was made and a narrative synthesis approach was used. The review proposal was registered with PROSPERO: CRD42022366159.

RESULTS

Twenty articles were included. Data were inconsistent throughout, with the overall trend suggesting no significant negative effects of statins on the parameters of physical activity, or on falls risk. This was especially true in matched and adjusted cohorts, where potential confounders had been accounted for.

CONCLUSION

This review did not identify a relationship between statin use and physical activity and falls risk in people aged 65 years and older. Ultimately, the risks and benefits of every medication should be considered in the context of each individual.

[Drug therapy for arterial hypertension and atrial fibrillation in frail patients : Are there any new insights and recommendations?]

The frail and elderly are considered to be at particular risk of suffering an adverse drug reaction. Empirical studies confirm the increased rate of adverse drug reactions. Whether frailty per se impairs drug metabolism or the underlying organ ageing processes and multimorbidity cannot be answered with certainty based on current data. Cardiovascular diseases exhibit a considerable interdependence with frailty. For example, there is a disproportionate syndromal interdependence between heart failure and frailty, and the typical ageing processes of the sinus node can be interpreted as heartbeat frailty. Multimorbidity in the elderly often includes a cluster of chronic cardiovascular diseases, often leading to the use of several cardiovascular medications as required. More recent definitions of polypharmacy assess the appropriateness of drugs rather than their number. The Fit-fOR-The-Aged (FORTA) list, the PRISCUS 2.0 list and the "Cochrane Library Special Collection on deprescribing", for example, offer a practice-oriented assessment aid. In the treatment of arterial hypertension, the target values for older people have also been set ever lower in recent years. In the case of frail elderly people, on the other hand, the guidelines do not specify a strict blood pressure target corridor; tolerability is the crucial factor here. When initiating antihypertensive therapy in frail individuals, one can consider monotherapy-in a departure from the standard case of dual combination therapy. The OPTIMISE study showed that discontinuation of one blood pressure medication did not lead to better tolerability of the drug therapy. Current studies come to differing conclusions regarding the risk-benefit assessment of new oral anticoagulants compared to vitamin K antagonists in the anticoagulation of frail elderly people with atrial fibrillation. Shared decision-making, which could improve adherence particularly in older people, is recommended.

Risk Assessment and Prevention of Falls in Older Community-Dwelling Adults: A Review

Importance

Falls are reported by more than 14 million US adults aged 65 years or older annually and can result in substantial morbidity, mortality, and health care expenditures.

Observations

Falls result from age-related physiologic changes compounded by multiple intrinsic and extrinsic risk factors. Major modifiable risk factors among community-dwelling older adults include gait and balance disorders, orthostatic hypotension, sensory impairment, medications, and environmental hazards. Guidelines recommend that individuals who report a fall in the prior year, have concerns about falling, or have gait speed less than 0.8 to 1 m/s should receive fall prevention interventions. In a meta-analysis of 59 randomized clinical trials (RCTs) in average-risk to high-risk populations, exercise interventions to reduce falls were associated with 655 falls per 1000 patient-years in intervention groups vs 850 falls per 1000 patient-years in nonexercise control groups (rate ratio [RR] for falls, 0.77; 95% CI, 0.71-0.83; risk ratio for number of people who fall, 0.85; 95% CI, 0.81-0.89; risk difference, 7.2%; 95% CI, 5.2%-9.1%), with most trials assessing balance and functional exercises. In a meta-analysis of 43 RCTs of interventions that systematically assessed and addressed multiple risk factors among individuals at high risk, multifactorial interventions were associated with 1784 falls per 1000 patient-years in intervention groups vs 2317 falls per 1000 patient-years in control groups (RR, 0.77; 95% CI, 0.67-0.87) without a significant difference in the number of individuals who fell. Other interventions associated with decreased falls in meta-analysis of RCTs and quasi-randomized trials include surgery to remove cataracts (8 studies with 1834 patients; risk ratio [RR], 0.68; 95% CI, 0.48-0.96), multicomponent podiatry interventions (3 studies with 1358 patients; RR, 0.77; 95% CI, 0.61-0.99), and environmental modifications for individuals at high risk (12 studies with 5293 patients; RR, 0.74; 95% CI, 0.61-0.91). Meta-analysis of RCTs of programs to stop medications associated with falls have not found a significant reduction, although deprescribing is a component of many successful multifactorial interventions.

Conclusions and Relevance

More than 25% of older adults fall each year, and falls are the leading cause of injury-related death in persons aged 65 years or older. Functional exercises to improve leg strength and balance are recommended for fall prevention in average-risk to high-risk populations. Multifactorial risk reduction based on a systematic clinical assessment for modifiable risk factors may reduce fall rates among those at high risk.

Development and internal validation of a dynamic fall risk prediction and monitoring tool in aged care using routinely collected electronic health data: a landmarking approach

OBJECTIVES

Falls pose a significant challenge in residential aged care facilities (RACFs). Existing falls prediction tools perform poorly and fail to capture evolving risk factors. We aimed to develop and internally validate dynamic fall risk prediction models and create point-based scoring systems for residents with and without dementia.

MATERIALS AND METHODS

A longitudinal cohort study using electronic data from 27 RACFs in Sydney, Australia. The study included 5492 permanent residents, with a 70%-30% split for training and validation. The outcome measure was the incidence of falls. We tracked residents for 60 months, using monthly landmarks with 1-month prediction windows. We employed landmarking dynamic prediction for model development, a time-dependent area under receiver operating characteristics curve (AUROCC) for model evaluations, and a regression coefficient approach to create point-based scoring systems.

RESULTS

The model identified 15 independent predictors of falls in dementia and 12 in nondementia cohorts. Falls history was the key predictor of subsequent falls in both dementia (HR 4.75, 95% CI, 4.45-5.06) and nondementia cohorts (HR 4.20, 95% CI, 3.87-4.57). The AUROCC across landmarks ranged from 0.67 to 0.87 for dementia and from 0.66 to 0.86 for nondementia cohorts but generally remained between 0.75 and 0.85 in both cohorts. The total point risk score ranged from -2 to 57 for dementia and 0 to 52 for nondementia cohorts.

DISCUSSION

Our novel risk prediction models and scoring systems provide timely person-centered information for continuous monitoring of fall risk in RACFs.

CONCLUSION

Embedding these tools within electronic health records could facilitate the implementation of targeted proactive interventions to prevent falls.

Fall risk factors among poly-medicated older Lebanese patients in primary care settings: a secondary cross-sectional analysis of the "MGPIDP-L project"

BACKGROUND

Falling is a major concern for the health of older adults and significantly affects their quality of life. Identifying the various risk factors and the differences between older patients can be challenging. The objective of this study was to identify the risk factors for falls among polymedicated community-dwelling older Lebanese patients following a medication review.

METHODS

In this analytical cross-sectional study, we examined the risk factors for falls in 850 patients aged ≥ 65 years who were taking ≥ 5 medications daily. The study involved conducting a medication review over the course of a year in primary care settings and using multivariate logistic regression analysis to analyze the data.

RESULTS

Our results showed that 106 (19.5%) of the 850 included patients had fallen at least once in the three months prior to the medication review. Loss of appetite and functional dependence were identified as the most significant predictors of falls ORa = 3.020, CI [2.074-4.397] and ORa = 2.877, CI [1.787-4.632], respectively. Other risk factors for falls included drowsiness ORa = 2.172, CI [1.499-3.145], and the use of beta-blockers ORa = 1.943, CI [1.339-2.820].

CONCLUSION

Our study highlights the importance of addressing multiple risk factors for falls among Lebanese older adults and emphasizes the need for customized interventions and ongoing monitoring to prevent falls and improve health outcomes. This study sheds light on a critical issue in the Lebanese older population and provides valuable insight into the complex nature of falls among poly-medicated Lebanese community-dwelling older adults.

Enhancing knowledge, attitude, and perceptions towards fall prevention among older adults: a pharmacist-led intervention in a primary healthcare clinic, Gemas, Malaysia

BACKGROUND

Falls and fall-related injuries are very common among older adults, and the risk of falls increases with the aging process. The lack of awareness of falls and fall-related injuries among older adults can contribute to an increasing risk of falls. Hence, a study was carried out to improve the knowledge, attitude, and perception of falls and fractures among older adults in a primary care setting in Gemas, a rural area of the Selangor state of Malaysia.

METHOD

A structured educational intervention was provided to older adults who visited the primary care setting in Gemas and provided written informed consent to participate in the study. A total of 310 older adult patients was included in the study using a convenience sampling technique.

RESULTS

Before the intervention, 74.84% of the respondents (n = 232) agreed that falls and related fractures are the leading causes of hospital admission among older adults. In post-intervention, the number of respondents who agreed with this statement increased to 257 (82.91%). At baseline, 28 respondents (9.03%) had poor knowledge, 160 respondents (51.61%) had average knowledge levels, and 122 respondents (39.35%) had good knowledge. In post-intervention, respondents with poor and average knowledge reduced to 1.93% (n = 6) and 29.35% (n = 91) respectively. A majority of respondents' knowledge levels improved significantly after the intervention (n = 213; 68.71%). About eight respondents (2.58%) had a negative perception of falls. In post-intervention, the percentage reduced to 0.65% as only two respondents had a negative perception. A total of 32 types of fall-risk-increasing drugs (FRIDs) have been prescribed to the respondents. A strong correlation (r = 0.89) between pre- and post-intervention knowledge was shown among the respondents. Paired t-test analysis showed a statistically significant difference.

CONCLUSION

The pharmacist-led educational intervention significantly improved the knowledge, attitude, and perception of falls among older adults. More structured and periodical intervention programmes are warranted to reduce the risk of falls and fractures among older adults.

Age-Related Risk of Serious Fall Events and Opioid Analgesic Use

Importance

Opioid analgesics may be associated with increased risk of falls, particularly among older adults.

Objective

To quantify the age-related risk of serious fall events among adults prescribed opioids by opioid exposure, time from initiation, and daily dose.

Design, Setting, and Participants

This population-based cohort study conducted in New South Wales, Australia, used data linking national pharmaceutical claims to national and state datasets, including information on sociodemographic characteristics, clinical characteristics, medicines use, health services utilization, and mortality (POPPY II study). It included adults (18 years or older) who initiated prescription opioid treatment, which was defined as no prior dispensing during the preceding 365 days, between January 1, 2005, and December 31, 2018. Data were analyzed from February to June 2023.

Exposure

Time-dependent periods of opioid exposure were evaluated from dispensing records.

Main Outcome and Measures

Serious fall events identified from emergency department, hospitalization, and mortality records. Negative binomial models were used to assess associations between time-dependent opioid exposure (overall, by time from initiation, and by dose), age, and risk of fall events. Models were adjusted for known fall risk factors, including other fall risk-increasing drugs, frailty risk, and prior serious fall events.

Results

The cohort comprised 3 212 369 individuals who initiated prescription opioid treatment (1 702 332 women [53%]; median [IQR] age at initiation, 49 [32-65] years). Overall, 506 573 serious fall events were identified, including 5210 fatal falls. During exposure to opioids, the risk of serious fall events was elevated among all age groups; compared with the group aged 18 to 44 years, this risk was highest among those 85 years or older (adjusted incident rate ratio, 6.35; 95% CI, 6.20-6.51). Across all age groups, the first 28 days following opioid initiation was a time of increased serious fall risk; this risk increased with age. Among individuals aged 18 to 84 years, associations were identified between higher daily opioid doses and serious fall events.

Conclusions and Relevance

The results of this cohort study suggest that prescription opioids were associated with increased risk of serious fall events among adults of all ages, with individuals 85 years or older at greatest risk. These risks should be considered when prescribing opioids, particularly for individuals with preexisting risk factors or when opioids are prescribed at higher doses. Targeted falls prevention efforts may be most effective within the first month following opioid initiation.

Ten-year association between change in speech-in-noise recognition and falls due to balance problems: a longitudinal cohort study

BACKGROUND

This study examined the relationship between speech-in-noise recognition and incident/recurrent falls due to balance problems ten years later (RQ-1); 10-year change in speech-in-noise recognition and falls (RQ-2a), as well as the role of dizziness in this relationship (RQ-2b). The association between hearing aid use and falls was also examined (RQ-3).

METHODS

Data was collected from the Netherlands Longitudinal Study on Hearing between 2006 and December 2022. Participants completed an online survey and digits-in-noise test every five years. For this study, data was divided into two 10-year follow-up time intervals: T0 (baseline) to T2 (10-year follow-up), and T1 (5-years) to T3 (15-years). For all RQs, participants aged ≥ 40 years at baseline, without congenital hearing loss, and non-CI users were eligible (n = 592). Additionally, for RQ-3 participants with a speech reception threshold in noise (SRTn) ≥ -5.5 dB signal-to-noise ratio were included (n = 422). Analyses used survey variables on hearing, dizziness, falls due to balance problems, chronic health conditions, and psychosocial health. Logistic regressions using General Estimating Equations were conducted to assess all RQs.

RESULTS

Among individuals with obesity, those with poor baseline SRTn had a higher odds of incident falls ten years later (odds ratio (OR):14.7, 95% confidence interval (CI) [2.12, 103]). A 10-year worsening of SRTn was significantly associated with a higher odds of recurrent (OR: 2.20, 95% CI [1.03, 4.71]) but not incident falls. No interaction was found between dizziness and change in SRTn. Hearing aid use (no use/ < 2 years use vs. ≥ 2 years) was not significantly associated with incident nor recurrent falls. Although there was a significant interaction with sex for this association, the effect of hearing aid use on incident/recurrent falls was not statistically significant among males nor females.

CONCLUSIONS

A longitudinal association between the deterioration in SRTn and recurrent falls due to balance problems after 10 years was confirmed in this study. This result stresses the importance of identifying declines in hearing earlier and justifies including hearing ability assessments within fall risk prevention programs. Mixed results of hearing aid use on fall risk warrant further investigation into the temporality of this association and possible differences between men and women.

Fall risk and cardiovascular outcomes of first-line antihypertensive medications in nursing home residents

BACKGROUND

Little evidence exists about the comparative effects of first-line antihypertensive medications (i.e., renin-angiotensin-aldosterone converting enzyme inhibitors (RAASi), amlodipine, or thiazide diuretics) in older adults with limited life expectancy. We compared the rates of injurious falls and short-term cardiovascular events between different first-line antihypertensive medication classes in adults receiving care in nursing homes (NH).

METHODS

This was a retrospective cohort of Medicare fee-for-service beneficiaries receiving care in NHs. Patients newly dispensed first-line antihypertensive medications were identified using Part D claims (2015-2018) and linked with clinical assessments (i.e., Minimum Data Set). Fall-related injuries (FRI), hip fractures, and major adverse cardiac events (MACE) outcomes were identified using hospitalization claims. Patients were followed from the date of antihypertensive dispensing until the occurrence of outcomes, death, disenrollment, or 6-month follow-up. Inverse-probability-of-treatment-weighted (IPTW) cause-specific hazards regression models were used to compare outcomes between patients who were new users of RAASi, amlodipine, or thiazides.

RESULTS

Our cohort included 16,504 antihypertensive users (RAASi, n = 9574; amlodipine, n = 5049; thiazide, n = 1881). Mean age was 83.5 years (± 8.2), 70.6% were female, and 17.2% were non-white race. During a mean follow-up of 5.3 months, 326 patients (2.0%) experienced an injurious fall, 1590 (9.6%) experienced MACE, and 2123 patients (12.9%) died. The intention-to-treat IPTW hazard ratio (HR) for injurious falls for amlodipine (vs RAASi) use was 0.85 (95% confidence interval (CI) 0.66-1.08) and for thiazides (vs RAASi) was 1.22 (95% CI 0.88-1.66). The rates of MACE were similar between those taking anti-hypertensive medications. Thiazides were discontinued more often than other classes; however, inferences were largely unchanged in as-treated analyses. Subgroup analyses were generally consistent.

CONCLUSIONS

Older adults with limited life expectancy experience similar rates of injurious falls and short-term cardiovascular events after initiating any of the first-line antihypertensive medications.

Development and external validation of the eFalls tool: a multivariable prediction model for the risk of ED attendance or hospitalisation with a fall or fracture in older adults

BACKGROUND

Falls are common in older adults and can devastate personal independence through injury such as fracture and fear of future falls. Methods to identify people for falls prevention interventions are currently limited, with high risks of bias in published prediction models. We have developed and externally validated the eFalls prediction model using routinely collected primary care electronic health records (EHR) to predict risk of emergency department attendance/hospitalisation with fall or fracture within 1 year.

METHODS

Data comprised two independent, retrospective cohorts of adults aged ≥65 years: the population of Wales, from the Secure Anonymised Information Linkage Databank (model development); the population of Bradford and Airedale, England, from Connected Bradford (external validation). Predictors included electronic frailty index components, supplemented with variables informed by literature reviews and clinical expertise. Fall/fracture risk was modelled using multivariable logistic regression with a Least Absolute Shrinkage and Selection Operator penalty. Predictive performance was assessed through calibration, discrimination and clinical utility. Apparent, internal-external cross-validation and external validation performance were assessed across general practices and in clinically relevant subgroups.

RESULTS

The model's discrimination performance (c-statistic) was 0.72 (95% confidence interval, CI: 0.68 to 0.76) on internal-external cross-validation and 0.82 (95% CI: 0.80 to 0.83) on external validation. Calibration was variable across practices, with some over-prediction in the validation population (calibration-in-the-large, -0.87; 95% CI: -0.96 to -0.78). Clinical utility on external validation was improved after recalibration.

CONCLUSION

The eFalls prediction model shows good performance and could support proactive stratification for falls prevention services if appropriately embedded into primary care EHR systems.

Experiences of Older Adults, Physiotherapists, and Aged Care Staff in the TOP UP Telephysiotherapy Program: Interview Study of the TOP UP Interventions

BACKGROUND

Telehealth provides opportunities for older adults to access health care. However, limited research exists on the use of telehealth within aged care services, particularly regarding physiotherapy-led fall prevention and mobility programs. Understanding the experiences and interactions of older adults, physiotherapists, and aged care service providers is crucial for the scale-up and sustainability of such essential programs. The TOP UP study, a hybrid type 1 effectiveness-implementation randomized controlled trial in aged care, used a supported multidisciplinary telephysiotherapy model to motivate older adults to engage in exercises to improve mobility and reduce falls.

OBJECTIVE

This qualitative substudy aims to achieve 2 primary objectives: to describe the experiences and acceptability of the TOP UP intervention for older people, physiotherapists, and aged care support workers and managers and to gain an in-depth understanding of program implementation.

METHODS

A purposive recruitment strategy was used to select 18 older adults who participated in the TOP UP intervention, ensuring variation in age, gender, residential status (home or residential aged care), geographic location, and cognitive levels. In addition, 7 physiotherapists, 8 aged care support workers, and 6 managers from 7 different aged care provider partners participated in this study. Semistructured interviews were conducted to explore stakeholders' experiences with the TOP UP program, gather suggestions for improvement, and obtain insights for the future implementation of similar telephysiotherapy programs. The interview framework and coding processes were informed by behavior changes and implementation frameworks. Data were analyzed using an abductive approach, informed by 2 behavioral change theories (Capability, Opportunity, Motivation, and Behavior Model and Self-Determination Theory) and the Nonadoption, Abandonment and Challenges to the Scale-Up, Spread and Sustainability of Health and Care Technologies framework.

RESULTS

All participants (n=39) reported high levels of acceptability for the TOP UP program and cited multiple perceived benefits. The thematic analysis generated 6 main themes: telephysiotherapy expands opportunity; tailored physiotherapy care with local support enhances motivation; engaging, older adult-friendly educational resources build capability; flexible reablement approach fosters autonomy; telephysiotherapy is safe, effective, and acceptable for many; and organizational commitment is required to embed telehealth. The motivation to exercise was enhanced by Zoom's convenience, use of tailored web-based exercise resources, and companionable local support.

CONCLUSIONS

This study highlights the inherent value of telephysiotherapy in aged care, emphasizing the need for investment in staff training, local support, and older adult-friendly resources in future telephysiotherapy iterations. TOP UP represents a convenient and flexible web-based care model that empowers many older adults to receive sustainable, high-quality care precisely when and where they need it.

Topic evolution before fall incidents in new fallers through natural language processing of general practitioners' clinical notes

BACKGROUND

Falls involve dynamic risk factors that change over time, but most studies on fall-risk factors are cross-sectional and do not capture this temporal aspect. The longitudinal clinical notes within electronic health records (EHR) provide an opportunity to analyse fall risk factor trajectories through Natural Language Processing techniques, specifically dynamic topic modelling (DTM). This study aims to uncover fall-related topics for new fallers and track their evolving trends leading up to falls.

METHODS

This case-cohort study utilised primary care EHR data covering information on older adults between 2016 and 2019. Cases were individuals who fell in 2019 but had no falls in the preceding three years (2016-18). The control group was randomly sampled individuals, with similar size to the cases group, who did not endure falls during the whole study follow-up period. We applied DTM on the clinical notes collected between 2016 and 2018. We compared the trend lines of the case and control groups using the slopes, which indicate direction and steepness of the change over time.

RESULTS

A total of 2,384 fallers (cases) and an equal number of controls were included. We identified 25 topics that showed significant differences in trends between the case and control groups. Topics such as medications, renal care, family caregivers, hospital admission/discharge and referral/streamlining diagnostic pathways exhibited a consistent increase in steepness over time within the cases group before the occurrence of falls.

CONCLUSIONS

Early recognition of health conditions demanding care is crucial for applying proactive and comprehensive multifactorial assessments that address underlying causes, ultimately reducing falls and fall-related injuries.

[Management of polypharmacy in older people with multimorbidity]

If the individual diagnoses of older people with multimorbidity are treated according to guidelines and by different specialists, confusing medication plans are sometimes the consequence. Therefore, a regular and structured drug evaluation is essential. As the life goals of patients can be very different, especially in older age, certain preliminary considerations should be made when starting, prescribing or discontinuing medication, taking into account the individual situation, including geriatric aspects. Updated so-called positive and negative lists provide assistance as to which medications are suitable or unsuitable for older people. Discontinuing certain medications when the life expectancy is reduced certainly makes sense but undertreatment of symptoms that cause distress to people, such as pain, should definitely be avoided.

Association of polypharmacy with occurrence of loneliness and social isolation among older adults

BACKGROUND

Polypharmacy is increasing. The longitudinal association of polypharmacy and social isolation has not been previously reported. The aim of this study was to explore longitudinal associations of polypharmacy with loneliness and social isolation among older adults.

METHODS

Participants aged 60 years and above in southern Sweden were invited for participation. A total of 1526 and 2556 participants were included in the separate analyses for loneliness and social isolation. Polypharmacy was defined as taking five or more medications. Associations of polypharmacy with occurrence of loneliness and social isolation were estimated using logistic regression models.

RESULTS

During follow-up, 409 and 414 participants developed loneliness and social isolation, respectively. The odds for loneliness occurrence were higher for participants with polypharmacy compared to participants without polypharmacy (OR, 1.37; 95% CI, 1.05-1.78; P = 0.020). For participants without polypharmacy, the probability of developing loneliness was 0.28 (95% CI, 0.25-0.31), while for those with polypharmacy this probability was 25% higher (0.35; 95% CI, 0.30-0.39). The odds for social isolation occurrence were higher for participants with polypharmacy compared to participants without polypharmacy (OR, 1.29; 95% CI, 1.02-1.64; P = 0.036). For participants without polypharmacy, the probability of developing social isolation was 0.16 (95% CI, 0.14-0.18), while for those with polypharmacy this probability was 18% higher (0.19; 95% CI, 0.17-0.22).

CONCLUSIONS

Polypharmacy was associated with loneliness and social isolation occurrence among older adults. Consideration of loneliness and social isolation are warranted when caring for older adults taking multiple medications.

The role of plasma concentrations and drug characteristics of beta-blockers in fall risk of older persons

Beta-blocker usage is inconsistently associated with increased fall risk in the literature. However, due to age-related changes and interindividual heterogeneity in pharmacokinetics and dynamics, it is difficult to predict which older adults are more at risk for falls. Therefore, we wanted to explore whether elevated plasma concentrations of selective and nonselective beta-blockers are associated with an increased risk of falls in older beta-blocker users. To answer our research question, we analyzed samples of selective (metoprolol, n = 316) and nonselective beta-blockers (sotalol, timolol, propranolol, and carvedilol, n = 179) users from the B-PROOF cohort. The associations between the beta-blocker concentration and time to first fall were assessed using Cox proportional hazard models. Change of concentration over time in relation to fall risk was assessed with logistic regression models. Models were adjusted for potential confounders. Our results showed that above the median concentration of metoprolol was associated with an increased fall risk (HR 1.55 [1.11-2.16], p = .01). No association was found for nonselective beta-blocker concentrations. Also, changes in concentration over time were not associated with increased fall risk. To conclude, metoprolol plasma concentrations were associated with an increased risk of falls in metoprolol users while no associations were found for nonselective beta-blockers users. This might be caused by a decreased β1-selectivity in high plasma concentrations. In the future, beta-blocker concentrations could potentially help clinicians estimate fall risk in older beta-blockers users and personalize treatment.
