Effectiveness of Hip Protectors to Reduce Risk for Hip Fracture from Falls in Long-Term Care

ObjectiveTo generate evidence of the effectiveness of hip protectors to minimize risk of hip fracture at the time of falling among residents of long-term care (LTC) by contrasting rates of hip fractures between falls with and without hip protectors.DesignA 12-month, retrospective cohort study. We retrospectively reviewed fall incident reports recorded during the 12 months prior to baseline in participating homes.Setting and participantsA population-based sample comprising all residents from 14 LTC homes owned and operated by a single regional health authority, who experienced at least 1 recorded fall during the 12-month study.ResultsAt baseline, the pooled mean (standard deviation) age of residents in participating homes was 82.7 (11.3) years and 68% were female. Hip protectors were worn in 2108 of 3520 (60%) recorded falls. Propensity to wear hip protectors was associated with male sex, cognitive impairment, wandering behavior, cardiac dysrhythmia, use of a cane or walker, use of anti-anxiety medication, and presence of urinary and bowel incontinence. The incidence of hip fracture was 0.33 per 100 falls in falls with hip protectors compared with 0.92 per 100 falls in falls without hip protectors, representing an unadjusted relative risk (RR) of hip fracture of 0.36 (95% confidence interval 0.14–0.90, P = .029) between protected and unprotected falls. After adjusting for propensity to wear hip protectors, the RR of hip fracture was 0.38 (95% confidence interval 0.14–0.99, P = .048) during protected vs unprotected falls.Conclusions and implicationsHip protectors were worn in 60% of falls, and the risk of hip fracture was reduced by nearly 3-fold by wearing a hip protector at the time of falling. Given that most clinical trials have failed to attain a similar level of adherence, our findings support the need for future research on the benefits of dissemination and implementation strategies to maximize adherence with hip protectors in LTC.     

Prevention of hip fracture by external hip protectors: an intervention in 17 nursing homes in two municipalities in Norway

AIMS: This study was undertaken to estimate the effect of hip protectors on the incidence of hip fracture when introduced into nursing homes as a regular part of the healthcare for all residents. METHODS: A pre-test/test design was used. The pre-intervention period lasted 18 months from May 1996. The intervention period lasted 18 months from May 1998. During the intervention period all residents (965 beds) in nursing homes in two municipalities in Norway were offered free use of hip protectors. The project manager provided motivational activities in the nursing homes during the whole period, aimed at increasing the participation rate. RESULTS: The intervention period showed a 39% reduction in the hip fracture incidence when compared with the pre-intervention period (p = 0.003). The percentage of daily users of the protector varied from 35% during the first months to 22% at the end of the period. Among the 61 persons who suffered a hip fracture 31 were registered as daily users. Fourteen of the 31 users were not wearing the protector when the hip fracture occurred, while five of the 31 had the protector on their knees. Twelve of the 31 suffered a hip fracture while properly wearing the protector. CONCLUSIONS: This non-randomized study showed that hip protectors introduced to all residents in nursing homes considerably reduced the incidence of hip fracture. It may be possible to achieve higher compliance and a further reduction in the incidence of hip fractures if the producers of hip protectors increase the comfort of the protector without reducing its effect. In addition, it is important that health workers encourage more individuals at high risk to use the protector.     

Prevention of fractures and the use of hip protectors in the elderly: it is still too early for recommendations

Hip fractures are a major health problem in the elderly. Several measures may reduce the number of hip fractures: prevention of falls, improving bone quality, and reducing the impact on the hip region during a fall; external hip protectors can be useful in this respect. Cluster-randomised studies have shown a significant reduction of hip fractures by 50% in elderly people wearing hip protectors who live in old-age homes or nursing homes and run an increased risk of falling. However, there is no evidence of a decreased number of hip fractures in studies in which individual randomisation was used. For elderly people living independently at home, there are still insufficient data on the effectiveness of hip protectors. An important problem with the use of hip protectors is the treatment compliance, which is generally very low. Many of the fractures in the intervention groups in published trials occurred at a time at which the protectors were not being worn. At present, there is too little evidence to decide definitely whether or not the use of hip protectors is useful.     

Calcium intake and hip fracture risk in men and women: a meta-analysis of prospective cohort studies and randomized controlled trials

BACKGROUND: The role of total calcium intake in the prevention of hip fracture risk has not been well established. OBJECTIVE: The objective of the study was to assess the relation of calcium intake to the risk of hip fracture on the basis of meta-analyses of cohort studies and clinical trials. RESULTS: In women (7 prospective cohort studies, 170,991 women, 2,954 hip fractures), there was no association between total calcium intake and hip fracture risk [pooled risk ratio (RR) per 300 mg total Ca/d = 1.01; 95% CI: 0.97, 1.05]. In men (5 prospective cohort studies, 68,606 men, 214 hip fractures), the pooled RR per 300 mg total Ca/d was 0.92 (95% CI: 0.82, 1.03). On the basis of 5 clinical trials (n = 5666 women, primarily postmenopausal, plus 1074 men) with 814 nonvertebral fractures, the pooled RR for nonvertebral fractures between calcium supplementation (800-1600 mg/d) and placebo was 0.92 (95% CI: 0.81, 1.05). On the basis of 4 clinical trials with separate results for hip fracture (6,504 subjects with 139 hip fractures), the pooled RR between calcium and placebo was 1.64 (95% CI:1.02, 2.64). Sensitivity analyses including 2 additional small trials with <100 participants or per-protocol results did not substantially alter results. CONCLUSIONS: Pooled results from prospective cohort studies suggest that calcium intake is not significantly associated with hip fracture risk in women or men. Pooled results from randomized controlled trials show no reduction in hip fracture risk with calcium supplementation, and an increased risk is possible. For any nonvertebral fractures, there was a neutral effect in the randomized trials.     

Sample size estimation for stratified individual and cluster randomized trials with binary outcomes

Individual randomized trials (IRTs) and cluster randomized trials (CRTs) with binary outcomes arise in a variety of settings and are often analyzed by logistic regression (fitted using generalized estimating equations for CRTs). The effect of stratification on the required sample size is less well understood for trials with binary outcomes than for continuous outcomes. We propose easy-to-use methods for sample size estimation for stratified IRTs and CRTs and demonstrate the use of these methods for a tuberculosis prevention CRT currently being planned. For both IRTs and CRTs, we also identify the ratio of the sample size for a stratified trial vs a comparably powered unstratified trial, allowing investigators to evaluate how stratification will affect the required sample size when planning a trial. For CRTs, these can be used when the investigator has estimates of the within-stratum intracluster correlation coefficients (ICCs) or by assuming a common within-stratum ICC. Using these methods, we describe scenarios where stratification may have a practically important impact on the required sample size. We find that in the two-stratum case, for both IRTs and for CRTs with very small cluster sizes, there are unlikely to be plausible scenarios in which an important sample size reduction is achieved when the overall probability of a subject experiencing the event of interest is low. When the probability of events is not small, or when cluster sizes are large, however, there are scenarios where practically important reductions in sample size result from stratification.     

Falls in the nursing home: are they preventable?

INTRODUCTION: Falls are prevalent in elderly patients residing in nursing homes, with approximately 1.5 falls occurring per nursing home bed-years. Although most are benign and injury-free, 10% to 25% result in hospital admission and/or fractures. Primary care providers for nursing home residents must therefore aim to reduce both the fall rate as well as the rate of fall-related morbidity in the long-term care setting. Interventions have been demonstrated to be successful in reducing falls in community-dwelling elderly patients. However, less evidence supports the efficacy of fall prevention in nursing home residents. METHODS: The authors conducted a Medline search using the key words Falls and Nursing Homes. RESULTS: Several studies examined the efficacy of multifaceted intervention programs on reducing falls in nursing homes with varied results. Components of these intervention programs include: environmental assessment, assistive device evaluation and modification, medication changes, gait assessment and training, staff education, exercise programs, hip protector use, and blood pressure evaluation. Current literature supports the use of environmental assessment and intervention in reducing falls in nursing homes, and demonstrates an association between certain medications and falls. However, there are no studies that examine the effect of medication adjustments on fall rates. Also, the literature does not strongly suggest that exercise programs are effective in fall reduction. Although not effective in reducing fall rates, the use of hip protectors appears to result in less fall-related morbidity. CONCLUSION: More studies must be done to clarify the effects of high-risk medication reduction, the optimal nature and intensity of exercise programs, and patient targeting criteria to maximize the effectiveness of nursing home fall prevention programs. Based on the current literature, an effective multifaceted fall prevention program for nursing home residents should include risk factor assessment and modification, staff education, gait assessment and intervention, assistive device assessment and optimization, as well as environmental assessment and modification. Although there is no association between the use of hip protectors and fall rates, their use should be encouraged because the ultimate goal of any fall prevention program is to prevent fall-related morbidity.     

The relation between hip fracture and alzheimer's disease in the canadian national population health survey health institutions data, 1994-1995. A cross-sectional study

PURPOSE: The purpose of this study is to examine the relation between hip fractures and Alzheimer's disease in institutionalized men and women who participated in the 1994-1995 Canadian National Population Health Survey (NPHS).METHODS: Participants in the institutional component of NPHS were randomly chosen from selected health care institutions from all provinces in Canada. A questionnaire, which assessed health, demographic and socio-economic status, risk factors, medication use, and falls, was administered by an interviewer. Proxy respondents were sought for residents who were ill or incapacitated. Logistic regression was used to examine the association between hip fractures and Alzheimer's disease in 408 men and 1105 women >/=65 years. Models were examined with either hip fracture or Alzheimer's disease as the dependent variable. Covariates that were assessed included osteoporosis, age group, sex, medications, reported falls and comorbid conditions.RESULTS: All hip fractures reported in this survey were the result of a fall, however only 3.7% of falls resulted in a hip fracture. Those who had sustained a hip fracture were more likely to have Alzheimer's disease (OR 2.0, 95% CI 1.1-3.5), osteoporosis (OR 4.3, 95% CI 2.5-7.4) and heart disease (OR 2.4, 95% CI 1.1-5.0). Respondents who had Alzheimer's disease were more likely to have sustained a hip fracture (OR 2.1 95% CI 1.2-3.6), to have osteoporosis (OR 1.9, 95% CI 1.5-2.5), and to have fallen (OR 1.4, 95% CI 1.1-1.8) and were less likely to be taking anti-psychotic medication (OR 0.4, 95% CI 0.3-0.6) than those with no diagnosis of Alzheimer's disease.CONCLUSIONS: There is an association between Alzheimer's disease and hip fractures that is independent of other covariates in this representative sample of institutionalized elderly Canadians.     

Effects of high-intensity progressive resistance training and targeted multidisciplinary treatment of frailty on mortality and nursing home admissions after hip fracture: a randomized controlled trial

RationaleExcess mortality and residual disability are common after hip fracture.HypothesisTwelve months of high-intensity weight-lifting exercise and targeted multidisciplinary interventions will result in lower mortality, nursing home admissions, and disability compared with usual care after hip fracture.DesignRandomized, controlled, parallel-group superiority study.SettingOutpatient clinicParticipantsPatients (n = 124) admitted to public hospital for surgical repair of hip fracture between 2003 and 2007.InterventionTwelve months of geriatrician-supervised high-intensity weight-lifting exercise and targeted treatment of balance, osteoporosis, nutrition, vitamin D/calcium, depression, cognition, vision, home safety, polypharmacy, hip protectors, self-efficacy, and social support.OutcomesFunctional independence: mortality, nursing home admissions, basic and instrumental activities of daily living (ADLs/IADLs), and assistive device utilization.ResultsRisk of death was reduced by 81% (age-adjusted OR [95% CI] = 0.19 [0.04–0.91]; P < .04) in the HIPFIT group (n = 4) compared with usual care controls (n = 8). Nursing home admissions were reduced by 84% (age-adjusted OR [95% CI] = 0.16 [0.04–0.64]; P < .01) in the experimental group (n = 5) compared with controls (n = 12). Basic ADLs declined less (P < .0001) and assistive device use was significantly lower at 12 months (P = .02) in the intervention group compared with controls. The targeted improvements in upper body strength, nutrition, depressive symptoms, vision, balance, cognition, self-efficacy, and habitual activity level were all related to ADL improvements (P < .0001–.02), and improvements in basic ADLs, vision, and walking endurance were associated with reduced nursing home use (P < .0001–.05).ConclusionThe HIPFIT intervention reduced mortality, nursing home admissions, and ADL dependency compared with usual care.

Frailty as a Predictor of All-Cause Mortality Among Older Nursing Home Residents: A Systematic Review and Meta-analysis

ObjectivesWe performed a meta-analysis based on prospective cohort studies to synthesize the pooled risk effect and to determine whether frailty is a predictor of all-cause mortality.DesignSystematic review and meta-analysis.SettingPubMed, EMBASE, and the Cochrane Library were systematically searched in October 2018. A random effects model was applied to combine the results according to the heterogeneity of the included studies.ParticipantsOlder nursing home residents.MeasurementsMortality risk due to frailty.ResultsFourteen studies (9076 participants) were included in this meta-analysis. Pooled results demonstrated that nursing home residents with frailty were at an increased risk of mortality [pooled hazards ratio (HR) = 1.88, 95% confidence interval (CI) = 1.57, 2.25, I² = 47.8%, P < .001] compared to those without frailty. Results of subgroup analyses showed that frailty was significantly associated with the risk of mortality among older nursing home residents when using FRAIL-NH (pooled HR = 2.10, 95% CI = 1.60-2.77, P < .001) and Frailty Index (pooled HR = 1.74, 95% CI = 1.40-2.18, P < .001) to define frail people, whereas when using the diagnosis criteria of CSHA-CFS for frailty, the pooled HR was 2.82 (95% CI = 0.79-10.10, P = .111). In addition, the subgroup analysis for length of follow-up showed that studies with a follow-up period of 1 year or more (pooled HR = 1.83, 95% CI = 1.52, 2.21, P < .001) reported a significantly higher rate of mortality among individuals with frailty, compared to those without frailty. Similar results were also found in studies with a follow-up period of less than 1 year (pooled HR = 2.67, 95% CI = 1.43, 5.00, P = .002).Conclusions and ImplicationsFrailty is a significant predictor of all-cause mortality in older nursing home residents. Therefore, there is an urgent need to screen for frailty in nursing home residents and carry out appropriate multidisciplinary intervention strategies to prevent poor outcomes and reduce the rate of mortality among older nursing home residents.     

The nursing home versus the hospital as the place of dying for nursing home residents in Japan

OBJECTIVES: To determine the characteristics of nursing home residents that are associated with dying in a nursing home versus a hospital in Japan. DESIGN: Retrospective case-control study. SETTING: A nonprofit nursing home with 110 beds in Tokyo, Japan. PARTICIPANTS: Eighty-six nursing home residents who died in the nursing home (n=43) or in a hospital (n=43) between 1 April 1999 and 30 September 2004. MEASUREMENTS: Nursing home records were reviewed to gain information regarding the following domains: demography, the family decision-maker, health status, resident and family preference for nursing home end-of-life care, and presence of a full-time physician. RESULTS: The variables older age [adjusted odds ratio (adjusted OR)=1.08, 95% confidence interval (95% CI)=1.01-1.17], the family decision-maker's preference for nursing home end-of-life care (adjusted OR=3.95, 95% CI=1.21-12.84), and presence of a full-time physician (adjusted OR=3.74, 95% CI=1.03-13.63) were associated with dying in the nursing home. CONCLUSION: Older age, the family's preference for nursing home end-of-life care, and the presence of a full-time physician were significantly related to dying in the nursing home versus in a hospital.

Correlates of falling during 24 h among elderly Danish community residents

OBJECTIVES: To identify dietary, medical, and environmental correlates of falling during the last 24 h among elderly community residents. The limited accuracy of recall of falls in the elderly in previous studies was the reason for a 24-h time frame. METHODS: The study composes 4281 community residents aged 66+ years. The statistical analyses included Pearson's chi(2) test and multiple logistic regression. RESULTS: Mutually independent correlates of falls were a family history of fracture (OR, 3.0; 95% CI: 1.3-7.1); osteoarthrosis of the knee (OR, 2.9; 95% CI: 1.3-6.2); dizziness (OR, 4.1; 95% CI: 1.9-8.9); a diet not including sour dairy products (OR, 3.0; 95% CI: 1.4-6.3) or fish (OR, 3.4; 95% CI: 1.5-7.5); drinking tea (OR, 5.8; 95% CI 2.15-15.30); needing help for shopping (OR, 3.9; 95% CI: 1.6-9.3); and for administration of medicine (OR, 9.0; 95% CI: 2.0-40.6). Independent environmental correlates were vinyl on the floor in the bathroom (OR, 6.6; 95% CI: 2.1-20.9) and using indoor footwear without soles (OR, 5.5; 95% CI: 2.3-13.4). CONCLUSION: The present analyses suggest that several factors are associated to the risk of falling among elderly community residents. It appears relevant for further studies to test if modifications of the potential risk factors identified may reduce falls among community dwelling older persons.     

The Orthogeriatrics Model of Care: Systematic Review of Predictors of Institutionalization and Mortality in Post-Hip Fracture Patients and Evidence for Interventions

Hip fracture is a common serious complication of osteoporosis, which is associated with high morbidity and mortality. In nursing home residents, incidence rates of hip fractures are at least twice to three times higher than in community-dwellers of the same age and sex. Older adults with hip fracture have a 5- to 8-fold increased risk for all-cause mortality and much higher risk of institutionalization. Therefore, interventions to prevent institutionalization, prevent a second fracture in institutionalized patients, and decrease mortality after a hip fracture are highly needed. The orthogeriatrics model of care is a shared-care approach to patients after suffering a hip fracture. This program, which has been studied in models run by geriatricians with the assistance of a multidisciplinary team, includes a comprehensive medical and nursing admission assessment focusing on the patient’s premorbid function, cognition, comorbidities, and risks is followed by a comprehensive care plan design. This systematic review describes and analyzes the interrelation between hip fracture and nursing home placement taking into consideration those evidence-based interventions to prevent later complications and future institutionalization.     

Cost-effectiveness of fracture prevention treatments in the elderly

OBJECTIVES: The cost-effectiveness of fracture prevention treatments (vitamin D and calcium and hip protectors) in male and female populations older than seventy years of age in the United-Kingdom was investigated. METHODS: A Markov model was developed to follow up, over lifetime, a hypothetical cohort of males and females at high-risk and general risk of fracture. Patients could sustain hip, wrist, vertebral, and/or other fractures. Fracture rates were obtained from population surveys in the United Kingdom. Effectiveness and quality of life data were identified from the clinical literature. Costs were those incurred by the UK National Health Service, and were obtained from several published sources. Uncertainty was explored through probabilistic sensitivity analysis. RESULTS: In the general-risk female (male) population, the incremental cost per Quality Adjusted Life Year (QALY) was dollar 11,722 (dollar 47,426) for hip protectors. In the male high-risk population, the incremental cost per QALY was dollar 17,017 for hip protectors. In the female high-risk population, hip protectors were cost-saving. Vitamin D and calcium alone was dominated by hip protectors in all four subgroups. CONCLUSIONS: Current information available on interventions to prevent fractures in the elderly in the United Kingdom, suggests that, at the decision-maker's ceiling ratio of dollar 20,000 per QALY, hip protectors are cost-effective in the general female population and high-risk male population, and cost-saving in the high-risk female population, despite the low compliance rate with the treatment.     

Variations in Nursing Home Discharge Rates for Urban and Rural Nursing Facility Residents With Hip Fracture

CONTEXT: The more limited availability and use of community-based long-term care services in rural areas may be a factor in higher rates of nursing home use among rural residents. PURPOSE: This study examined differences in the rates of nursing home discharge for older adults receiving posthospital care in a nursing facility. METHODS: The study sample was comprised of a cohort of rural and urban residents newly admitted to nursing home care in Maine following surgery for hip fracture. FINDINGS: The results indicated that rural residents who were hospitalized for hip fracture and subsequently admitted to a nursing facility for rehabilitation were significantly less likely than urban residents to be discharged within the first 30 days of their admission. Rural residents who stayed in the nursing facility beyond 30 days were also less likely to be discharged in the first 6 months. These geographic differences were not explained by service use and resident characteristics such as age, health, or functional status. CONCLUSIONS: The finding of lower discharge rates among rural nursing facility residents appears to be consistent with previous studies demonstrating higher rates of nursing home use among rural residents. There continues to be a need for a better understanding of the role that service supply and accessibility and other factors play in the patterns and outcomes of rural long-term care.     

Underutilization of calcium and vitamin D supplements in an academic long-term care facility

BACKGROUND: Good scientific evidence indicates that calcium and vitamin D supplementation decrease the incidence of osteoporosis-related fractures among institutionalized elderly. OBJECTIVE: The objective was to study the frequency of prescribing calcium and vitamin D supplements in elderly institutionalized individuals in a large community teaching nursing home. METHODS: A cross-sectional chart review study of 177 consecutively located elderly residents from an 899-bed academic long-term care facility. RESULTS: Calcium and vitamin D supplements were prescribed in only 12% and 9% of subjects, respectively. Among subjects with the diagnosis of osteoporosis (n = 12), 66% were prescribed calcium and 58% were prescribed vitamin D supplements. Among subjects with hip fractures (n = 8), only 25% were prescribed calcium with a similar percentage prescribed vitamin D supplements. Female residents were more likely than male residents to receive calcium (P <0.05) and vitamin D supplements (P = 0.08). CONCLUSION: There is a major need to increase the utilization of calcium and vitamin D supplementation among institutionalized elderly to decrease the risk of osteoporotic fractures, including hip fractures.

Objectives

To investigate the prevalence and associated factors of sarcopenia defined by different criteria in nursing home residents.

Time Trends in Opioid Use by Dementia Severity in Long-Term Care Nursing Home Residents

ObjectiveCurrent information on opioid use in nursing home residents, particularly those with dementia, is unknown. We examined the temporal trends in opioid use by dementia severity and the association of dementia severity with opioid use in long-term care nursing home residents.DesignRepeated measures cross-sectional study.SettingLong-term care nursing homes.ParticipantsUsing 20% Minimum Data Set (MDS) and Medicare claims from 2011-2017, we included long-term care residents (n = 734,739) from each year who had 120 days of consecutive stay. In a secondary analysis, we included residents who had an emergency department visit for a fracture (n = 12,927).MeasurementsDementia was classified as no, mild, moderate, and severe based on the first MDS assessment each year. In the 120 days of nursing home stay, opioid use was measured as any, prolonged (>90 days), and high-dose (≥90 morphine milligram equivalent dose/day). For residents with a fracture, opioid use was measured within 7 days after emergency department discharge. Association of dementia severity with opioid use was evaluated using logistic regression.ResultsOverall, any opioid use declined by 8.5% (35.2% to 32.2%, P < .001), prolonged use by 5.0% (14.1% to 13.4%, P < .001), and high-dose by 21.4% (1.4% to 1.1%, P < .001) from 2011 to 2017. Opioid use declined across 4 dementia severity groups. Among residents with fracture, opioid use declined by 9% in mild, 9.5% in moderate, and 12.3% in severe dementia. The odds of receiving any, prolonged, and high-dose opioids decreased with increasing severity of dementia. For example, severe dementia reduced the odds of any [23.5% vs 47.6%; odds ratio (OR) 0.56, 95% confidence interval (CI) 0.55-0.57], prolonged (9.8% vs 20.7%; OR 0.69, 95% CI 0.67-0.71), and high-dose (1.0% vs 2.3%; OR 0.69, 95% CI 0.63-0.74) opioids.Conclusions and ImplicationsUse of opioids declined in nursing home residents from 2011 to 2017, and the use was lower in residents with dementia, possibly reflecting suboptimal pain management in this population.
