de Bot RTAL, Veldman HD, Witlox AM, van Rhijn LW, Hiligsmann M. Hip protectors are cost-effective in the prevention of hip fractures in patients with high fracture risk. Osteoporos Int 2020; 31:1217-1229. [PMID: 32040600 DOI: 10.1007/s00198-019-05252-8] [Citation(s) in RCA: 13] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/05/2019] [Accepted: 11/29/2019] [Indexed: 12/01/2022]
Abstract
Cost-effective preventive interventions are necessary for tackling the increasing number of hip fractures, which are frequently occuring as a serious consequence of osteoporosis. Several interventions have been available for preventing and treating osteoporosis. The aim of this study was to systematically review and critically appraise studies that assessed cost-effectiveness of hip protectors for the prevention of hip fractures and to investigate the effects of age, gender and residence situation on cost-effectiveness. A systematic review was conducted in order to identify economic evaluation studies examining the hip protector solely or compared to no treatment according to the Preferred Reported Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. Synthesis of results was performed to observe trends between the studies. Methodological quality of the studies was assessed by the use of the Quality of Health Economic Studies (QHES) instrument. A total of 15 economic evaluation studies were included for analysis. The methodological quality was high in most studies (13/15). The hip protector was solely evaluated in three studies and within 12 other studies compared with no intervention. All studies that investigated the cost-effectiveness in long-term care facilities revealed that hip protector use is a cost-effective strategy for the prevention of hip fractures in elderly. Cost-effectiveness was also observed in two studies that provided hip protectors in a geriatric hospital ward. Four studies included both community-dwelling residents and residents living in a long-term care facility in their study. These studies showed more variability regarding cost-effectiveness. One study did not report information regarding the residence situation of their cohort, but also observed cost-effectiveness. In conclusion, this review suggests that hip protectors are a cost-effective approach in the prevention of hip fractures in populations with high risk of hip fractures especially in long-term care facilities and a geriatric ward in a hospital.

Validation and psychometric properties of the commitment to hip protectors (C-HiP) index in long-term care providers of British Columbia, Canada: a cross-sectional survey. BMC Geriatr 2017; 17:103. [PMID: 28468679 PMCID: PMC5415742 DOI: 10.1186/s12877-017-0493-5] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/19/2016] [Accepted: 04/25/2017] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND If worn during a fall, hip protectors substantially reduce risk for hip fracture. However, a major barrier to their clinical efficacy is poor user adherence. In long-term care, adherence likely depends on how committed care providers are to hip protectors, but empirical evidence is lacking due to the absence of a psychometrically valid assessment tool. METHODS We conducted a cross-sectional survey in a convenience sample of 529 paid care providers. We developed the 15-item C-HiP Index to measure commitment, comprised of three subscales: affective, cognitive and behavioural. Responses were subjected to hierarchical factor analysis and internal consistency testing. Eleven experts rated the relevance and clarity of items on 4-point Likert scales. We performed simple linear regression to determine whether C-HiP Index scores were positively related to the question, "Do you think of yourself as a champion of hip protectors", rated on a 5-point Likert scale. We examined whether the C-HiP Index could differentiate respondents: (i) who were aware of a protected fall causing hip fracture from those who were unaware; (ii) who agreed in the existence of a champion of hip protectors within their home from those who didn't. RESULTS Hierarchical factor analysis yielded two lower-order factors and a single higher-order factor, representing the overarching concept of commitment to hip protectors. Items from affective and cognitive subscales loaded highest on the first lower-order factor, while items from the behavioural subscale loaded highest on the second. We eliminated one item due to low factor matrix coefficients, and poor expert evaluation. The C-HiP Index had a Cronbach's alpha of 0.96. A one-unit increase in championing was associated with a 5.2-point (p < 0.01) increase in C-HiP Index score. Median C-HiP Index scores were 4.3-points lower (p < 0.01) among respondents aware of a protected fall causing hip fracture, and 7.0-points higher (p < 0.01) among respondents who agreed in the existence of a champion of hip protectors within their home. CONCLUSIONS We offer evidence of the psychometric properties of the C-HiP Index. The development of a valid and reliable assessment tool is crucial to understanding the factors that govern adherence to hip protectors in long-term care.

Facilitators of and barriers to hip protector acceptance and adherence in long-term care facilities: a systematic review. J Am Med Dir Assoc 2016; 16:185-93.

Abstract
BACKGROUND Hip protectors represent an attractive strategy for reducing hip fractures among high-risk fallers in long-term care facilities. However, clinical studies yield conflicting results regarding their clinical value. This is mainly due to poor acceptance and adherence among users in wearing these devices. As a result, there is an urgent need to identify potential barriers and facilitators to initial acceptance and continued adherence with hip protector use. PURPOSE The objective of this systematic review is to synthesize available research evidence to identify factors that influence acceptance and adherence among older adults living in long-term care facilities. METHODS A key word search was conducted for studies published in English between 2000 and 2013 that employed quantitative, qualitative, or mixed-methods research designs. Two independent reviewers evaluated each article for inclusion, with a third reviewer when needed to resolve discrepancies. RESULTS Twenty-eight articles met our inclusion criteria, and facilitators and barriers were clustered into 4 socio-ecological levels: system (eg, facility commitment, staff shortages), caregiver (eg, belief in the efficacy of protectors, negative perceptions), resident (eg, clinical risk factors for falls and related fractures, acute illness), and product (eg, soft shell, discomfort). DISCUSSION The outcomes provide decision makers, health professionals, and caregivers with a greater awareness of strategies to improve compliance with the use of hip protectors. Furthermore, researchers can use this information to design clinical trials that yield high acceptance and adherence.

Abstract
UNLABELLED In this study, we determined the cost-effectiveness of hip protector use compared with no hip protector on a geriatric ward in Germany. From both the societal and the statutory health insurance (SHI) perspectives, the cost-effectiveness ratios for the provision of hip protectors were below <euro>12,000/quality-adjusted life year (QALY) even if unrelated costs in added life years were included. INTRODUCTION The aim of this study is to determine the cost-effectiveness of the provision of hip protectors compared with no hip protectors on a geriatric ward in Germany. METHODS A lifetime decision-analytic Markov model was developed. Costs were measured from the societal and from the statutory health insurance (SHI) perspectives and comprised direct medical, non-medical and unrelated costs in additional life years gained. Health outcomes were measured in terms of quality-adjusted life years (QALYs). To reflect several levels of uncertainty, first- and second-order Monte Carlo simulation (MCS) approaches were applied. RESULTS Hip protector use compared with no hip protector results in savings (costs, -5.1/QALYs, 0.003) for the societal perspective. For the SHI perspective, the incremental cost-effectiveness ratio was <euro>4416 <euro>/QALY (costs, +13.4). If unrelated costs in life years gained were included, the cost-effectiveness ratio increases to <euro>9794/QALY for the societal perspective and to <euro>11,426/QALY for the SHI perspective. In the MCS, for the societal perspective without unrelated costs, 47 % of simulations indicated hip protectors to be cost saving (i.e. lower costs and higher effects). CONCLUSION Although the gain in QALYs due to the provision of providing hip protectors to patients on geriatric wards is small, all scenarios showed acceptable cost-effectiveness ratios or even savings.

Abstract
BACKGROUND Older people living in nursing care facilities or older adults living at home are at high risk of falling and a hip fracture may occur after a fall. Hip protectors have been advocated as a means to reduce the risk of hip fracture. Hip protectors are plastic shields (hard) or foam pads (soft), usually fitted in pockets in specially designed underwear.This is an update of a Cochrane review first published in 1999, and updated several times, most recently in 2010. OBJECTIVES To determine if the provision of external hip protectors (sometimes referred to as hip pads or hip protector pads) reduces the risk of fracturing the hip in older people. SEARCH METHODS We searched the Cochrane Bone, Joint and Muscle Trauma Group Specialised Register (December 2012), the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library 2012, Issue 12), MEDLINE (1950 to week 3 November 2012), MEDLINE In-Process (18 December 2012), EMBASE (1988 to 2012 Week 50), CINAHL (1982 to December 2012), BioMed Central (January 2010), trial registers and reference lists of relevant articles. SELECTION CRITERIA All randomised or quasi-randomised controlled trials comparing an intervention group provided with hip protectors with a control group not provided with hip protectors. DATA COLLECTION AND ANALYSIS Two review authors independently assessed risk of bias and extracted data. We sought additional information from trialists. Data were pooled using fixed-effect or random-effects models as appropriate. MAIN RESULTS This review includes 19 studies, nine of which were cluster randomised. These included approximately 17,000 people (mean age range 78 to 86 years). Most studies were overall at low risk of bias for fracture outcomes. Trials tested hard or soft hip protectors enclosed in special underwear in 18 studies.Pooling of data from 14 studies (11,808 participants) conducted in nursing or residential care settings found moderate quality evidence for a small reduction in hip fracture risk (risk ratio (RR) 0.82, 95% confidence interval (CI) 0.67 to 1.00); the absolute effect is 11 fewer people (95% CI, from 20 fewer to 0) per 1000 having a hip fracture when provided with hip protectors.There is moderate quality evidence when pooling data from five trials in the community (5614 participants) that shows little or no effect in hip fracture risk (RR 1.15, 95% CI 0.84 to 1.58); the absolute effect is two more people (95% CI 2 fewer to 6 more) per 1000 people having a hip fracture when provided with hip protectors.There is probably little to no effect on falls (rate ratio 1.02, 95% CI 0.9 to 1.16) or fractures other than of the hip or pelvis (rate ratio 0.87, 95% CI 0.71 to 1.07). However, the risk ratio for pelvic fractures is RR 1.27 (95% CI 0.78 to 2.08); this is an absolute effect of one more person (95% CI 1 fewer to 5 more) per 1000 having a pelvic fracture when provided with hip protectors.The incidence of adverse events while wearing hip protectors, including skin irritation, ranged from 0% to 5%. Adherence, particularly in the long term, was poor. AUTHORS' CONCLUSIONS Hip protectors probably reduce the risk of hip fractures if made available to older people in nursing care or residential care settings, without increasing the frequency of falls. However, hip protectors may slightly increase the small risk of pelvic fractures. Poor acceptance and adherence by older people offered hip protectors is a barrier to their use. Better understanding is needed of the personal and design factors that may influence acceptance and adherence.

Abstract
Osteoporosis is a chronic disorder of the skeleton causing increased bone fragility and fractures. In the second of our 3-part series, we discuss the beneficial effects of nonpharmacologic agents in the management of osteoporosis. We review the evidence supporting the use of exercise, whole-body vibration, hip protectors, low-intensity pulsed ultrasound, bracing, and vertebral augmentation procedures. The mechanism of action, precautions, and expected outcomes are discussed. Nonpharmacologic management of osteoporosis blends in very well with an overall exercise prescription. The nonpharmacologic interventions discussed are readily available and easy to implement. The use of such techniques demonstrates the important role of the physiatrist in the management of osteoporosis.

Abstract
BACKGROUND Hip fracture in older people usually results from a fall on the hip. Hip protectors have been advocated as a means to reduce the risk of hip fracture. OBJECTIVES To determine if external hip protectors reduce the incidence of hip fractures in older people following a fall. SEARCH STRATEGY We searched the Cochrane Bone, Joint and Muscle Trauma Group Specialised Register (January 2010), The Cochrane Library 2010, Issue 2, MEDLINE (1950 to November 2009), MEDLINE in-process (30 December 2009), EMBASE (1988 to 2009 week 52), CINAHL (1982 to February 2009), BioMed Central (January 2010) and reference lists of relevant articles. SELECTION CRITERIA All randomised or quasi-randomised controlled trials comparing the use of hip protectors with an unprotected control group. DATA COLLECTION AND ANALYSIS Two authors independently assessed risk of bias and extracted data. We sought additional information from trialists. Data were pooled using fixed-effect or random-effects models as appropriate. MAIN RESULTS Pooling of data from 13 studies (11,573 participants) conducted in nursing or residential care settings found a marginally significant reduction in hip fracture risk (risk ratio (RR) 0.81, 95% confidence interval (CI) 0.66 to 0.99); statistical significance was lost following exclusion of five studies (3757 participants) assessed at high risk of bias (RR 0.93, 95% CI 0.74 to 1.18).Pooling of data from three trials (5135 community-dwelling participants) showed no evidence of reduction in hip fracture risk (RR 1.14, 95% CI 0.83 to 1.57).There was no evidence of a statistically significant effect on incidence of pelvic or other fractures, or on rate of falls. No important adverse effects of the hip protectors were reported but adherence, particularly in the long term, was poor. AUTHORS' CONCLUSIONS The effectiveness of the provision of hip protectors in reducing the incidence of hip fracture in older people is still not clearly established, although they may reduce the rate of hip fractures if made available to frail older people in nursing care. It remains unknown from studies identified to date if these findings apply to all types of hip protectors. Some cluster-randomised trials have been associated with high risk of bias. Poor acceptance and adherence by older people offered hip protectors have been key factors contributing to the continuing uncertainty.

Abstract
Background Injuries are a major cause of mortality and morbidity which together result in avoidable societal costs. Due to limited resources, injury prevention interventions need to demonstrate cost-effectiveness to justify their implementation. However, the existing knowledge in this area is limited. Consequently, a systematic review is needed to support decision-making and to assist in the targeting of future research. The aim of this review is to critically appraise the published economic evidence of injury prevention interventions at the municipal level. Methods A search strategy was developed to focus a literature search in PubMed, Embase, Cochrane and NHS EED. Studies were eligible for inclusion if they were economic evaluations of injury prevention interventions that could be implemented by municipalities; had a relevant comparison group; did not include any form of medication or drug use; and were assessed as having at least an acceptable quality from an economic point of view. Articles were screened in three steps. In the final step, studies were critically appraised using a check-list based on Drummond's check-list for assessing economic evaluations. Results Of 791 potential articles 20 were accepted for inclusion. Seven studies showed net savings; four showed a cost per health score gained; six showed both savings and a cost per health score gained but for different time horizons and populations; and three showed no effect. The interventions targeted a range of areas such as traffic safety, fire safety, hip fractures, and sport injuries. One studied a multi-targeted community-based program. Only six articles used effectiveness data generated within the study. Conclusions The results indicate that there are injury prevention interventions that offer good use of societal resources. However, there is a lack of economic evidence surrounding injury prevention interventions. This lack of evidence needs to be met by further research about the economic aspects of injury prevention interventions to improve the information available for decision-making.

Abstract
Prevention of fractures in the elderly consists of prevention and treatment of osteoporosis, prevention of falling and prevention of fractures using injury-site protection. Since the majority of hip fractures in elderly people are caused by a sideways fall with direct impact on the greater trochanter of the proximal femur, one option to prevent the fracture is a biomechanically effective external hip protector. The biomechanical test results of an energy-shunting and energy-absorbing hip protector have demonstrated that this type of hip protector can provide an effective impact force attenuation in typical falling conditions of older adults by reducing the initial force down to the seventh part. Recent meta-analyses and systematic reviews combining findings of all different types of hip protectors suggest that in care homes and institutions with high rates of hip fracture, the use of hip protectors might help to reduce the risk of fracture to 20–60%, but there is no evidence of a public health level benefit from hip protectors for lower-risk (usually home-dwelling) elderly people.

OBJECTIVE To determine the long-term cost-effectiveness of hip protector use in the prevention of hip fractures in elderly institutionalized residents in Germany compared to no prevention. METHODS A lifetime Markov decision model was developed using published data on costs and health outcomes. A societal and statutory health insurance perspective was adopted. RESULTS From a societal/statutory health insurance perspective, use of hip protectors yields savings of 315 EURO/257 EURO and a gain of 0.13 quality-adjusted life years per person over lifetime. CONCLUSION Hip protector use in elderly institutionalized residents in Germany is highly cost-effective.
