Cost-effectiveness of a multifactorial fracture prevention program for elderly people admitted to nursing homes

Models for delivery and co-ordination of primary or secondary health care (or both) to older adults living in aged care facilities

BACKGROUND

The number of older people is increasing worldwide and public expenditure on residential aged care facilities (ACFs) is expected to at least double, and possibly triple, by 2050. Co-ordinated and timely care in residential ACFs that reduces unnecessary hospital transfers may improve residents' health outcomes and increase satisfaction with care among ACF residents, their families and staff. These benefits may outweigh the resources needed to sustain the changes in care delivery and potentially lead to cost savings. Our systematic review comprehensively and systematically presents the available evidence of the effectiveness, safety and cost-effectiveness of alternative models of providing health care to ACF residents.

OBJECTIVES

Main objective To assess the effectiveness and safety of alternative models of delivering primary or secondary health care (or both) to older adults living in ACFs. Secondary objective To assess the cost-effectiveness of the alternative models.

SEARCH METHODS

We searched CENTRAL, MEDLINE, Embase, five other databases and two trials registers (WHO ICTRP, ClinicalTrials.gov) on 26 October 2022, together with reference checking, citation searching and contact with study authors to identify additional studies.

SELECTION CRITERIA

We included individual and cluster-randomised trials, and cost/cost-effectiveness data collected alongside eligible effectiveness studies. Eligible study participants included older people who reside in an ACF as their place of permanent abode and healthcare professionals delivering or co-ordinating the delivery of healthcare at ACFs. Eligible interventions focused on either ways of delivering primary or secondary health care (or both) or ways of co-ordinating the delivery of this care. Eligible comparators included usual care or another model of care. Primary outcomes were emergency department visits, unplanned hospital admissions and adverse effects (defined as infections, falls and pressure ulcers). Secondary outcomes included adherence to clinical guideline-recommended care, health-related quality of life of residents, mortality, resource use, access to primary or specialist healthcare services, any hospital admissions, length of hospital stay, satisfaction with the health care by residents and their families, work-related satisfaction and work-related stress of ACF staff.

DATA COLLECTION AND ANALYSIS

Two review authors independently selected studies for inclusion, extracted data, and assessed risk of bias and certainty of evidence using GRADE. The primary comparison was any alternative model of care versus usual care.

MAIN RESULTS

We included 40 randomised trials (21,787 participants; three studies only reported number of beds) in this review. Included trials evaluated alternative models of care aimed at either all residents of the ACF (i.e. no specific health condition; 11 studies), ACF residents with mental health conditions or behavioural problems (12 studies), ACF residents with a specific condition (e.g. residents with pressure ulcers, 13 studies) or residents requiring a specific type of care (e.g. residents after hospital discharge, four studies). Most alternative models of care focused on 'co-ordination of care' (n = 31). Three alternative models of care focused on 'who provides care' and two focused on 'where care is provided' (i.e. care provided within ACF versus outside of ACF). Four models focused on the use of information and communication technology. Usual care, the comparator in all studies, was highly heterogeneous across studies and, in most cases, was poorly reported. Most of the included trials were susceptible to some form of bias; in particular, performance (89%), reporting (66%) and detection (42%) bias. Compared to usual care, alternative models of care may make little or no difference to the proportion of residents with at least one emergency department visit (risk ratio (RR) 1.01, 95% confidence interval (CI) 0.84 to 1.20; 7 trials, 1276 participants; low-certainty evidence), but may reduce the proportion of residents with at least one unplanned hospital admission (RR 0.74, 95% CI 0.56 to 0.99, I2 = 53%; 8 trials, 1263 participants; low-certainty evidence). We are uncertain of the effect of alternative models of care on adverse events (proportion of residents with a fall: RR 1.15, 95% CI 0.83 to 1.60, I² = 74%; 3 trials, 1061 participants; very low-certainty evidence) and adherence to guideline-recommended care (proportion of residents receiving adequate antidepressant medication: RR 5.29, 95% CI 1.08 to 26.00; 1 study, 65 participants) as the certainty of the evidence is very low. Compared to usual care, alternative models of care may have little or no effect on the health-related quality of life of ACF residents (MD -0.016, 95% CI -0.036 to 0.004; I² = 23%; 12 studies, 4016 participants; low-certainty evidence) and probably make little or no difference to the number of deaths in residents of ACFs (RR 1.03, 95% CI 0.92 to 1.16, 24 trials, 3881 participants, moderate-certainty evidence). We did not pool the cost-effectiveness or cost data as the specific costs associated with the various alternative models of care were incomparable, both across models of care as well as across settings. Based on the findings of five economic evaluations (all interventions focused on co-ordination of care), we are uncertain of the cost-effectiveness of alternative models of care compared to usual care as the certainty of the evidence is very low.

AUTHORS' CONCLUSIONS

Compared to usual care, alternative models of care may make little or no difference to the number of emergency department visits but may reduce unplanned hospital admissions. We are uncertain of the effect of alternative care models on adverse events (i.e. falls, pressure ulcers, infections) and adherence to guidelines compared to usual care, as the certainty of the evidence is very low. Alternative models of care may have little or no effect on health-related quality of life and probably have no effect on mortality of ACF residents compared to usual care. Importantly, we are uncertain of the cost-effectiveness of alternative models of care due to the limited, disparate data available.

Developing a fall prevention intervention economic model

PURPOSE

Model-based economic evaluations require conceptualization of the model structure. Our objectives were to identify important health states, events, and patient attributes to be included in a model-based cost-effectiveness analysis of fall prevention interventions, to develop a model structure to examine cost-effectiveness of fall prevention interventions, and to assess the face validity of the model structure.

METHODS

An expert panel comprising clinicians, health service researchers, health economists, a patient partner, and policy makers completed two rounds of online surveys to gain consensus on health states, events, and patient attributes important for fall prevention interventions. The surveys were informed by a literature search on fall prevention interventions for older adults (≥65 years) including economic evaluations and clinical practice guidelines. The results of the Delphi surveys and subsequent discussions can support the face validity of a state-transition model for an economic evaluation of fall prevention interventions.

RESULTS

In total, 11 experts rated 24 health states/events and 41 patient attributes. Consensus was achieved on 14 health states/events and 26 patient characteristics. The proposed model structure incorporated 12 of the 14 selected health states/events. Panelists confirmed the face validity of the model structure during teleconferences.

CONCLUSIONS

There is a dearth of studies presenting the model conceptualization process; consequently, this study involving multiple end user partners with opportunities for input at several stages adds to the literature as another case study. This process is an example of how a fall prevention economic model was developed using a modified Delphi process and assessed for face validity.

A Study on the Effect of Nursing Intervention Based on Health Behavior Change Integration Theory on Patients with Limb Fracture and Its Effect on Limb Function and Self-Efficacy

Objective

To assess the impact on nursing care based on the theory of health behavior change integration in patients with limb fracture and its effect on limb function and self-efficacy.

Methods

The starting and ending time of this study is from February 2021 to February 2022. In this study, 116 hospitalized patients with limb fracture were selected as the object of study. According to the method of random number table, the patients were divided into study group and control group. The patients of the study cohort were given nursing healthcare based on the theory of health behavior change integration, while those in the control cohort were given common nursing. The scores of self-rating anxiety scale (SAS), self-rating depression scale (SDS), Frankl compliance scale, self-efficacy scale (GSES), activity of daily living scale (ADL), and Fugl-Meyer limb motor function assessment (FMA) were studied before and 3 months after nursing.

Results

After 3 months of nursing, the SAS and SDS scores of the study group were lower than those of the control group, and the difference between groups was statistically significant (p < 0.05). After 3 months of nursing, the scores of Frankl scale, GSES, ADL scale, and FMA scale in the study group were higher than those in the control group, and the difference between groups was statistically significant (p < 0.05).

Conclusion

The value of nursing interventions based on the integration of health behavior change theory is even more significant in patients with limb fractures. It is more helpful in reducing patients' anxiety and depression, increasing compliance and improving limb function. Self-efficacy and daily living skills were also significantly improved.

Cost-Effectiveness of Multifactorial Interventions in Preventing Falls among Elderly Population: A Systematic Review

Objective:

To review the cost-effectiveness of multifactorial interventions to prevent falls in elderly people.

Methods:

In this systematic review, the databases including PubMed via MEDLINE, Web of Science, Embase, Scopus, Cochrane Library and Google Scholar (from 1st January 2000 to 30^th February) were used. All pre-reviewed articles related to cost-effectiveness analysis of multifactorial interventions to prevent falls in elderly were included in this paper and congresses abstracts were excluded. Descriptive statistics were used for quantitative data and content-analysis method to analyze qualitative data.

Results:

Out of the 456 articles, 19 were finally included in the study. Eighteen articles were conducted in High-Income Countries (HICs) and 16 were at the community level. Medical visits consultation and education were the most common interventions. Most studies were cost-effectiveness and using the Randomized Control Trial (RCT) methods. A fall of prevention costs ranged from $ 272 to $ 987. Incremental Cost-Effectiveness Ratio (ICER) interventions also ranged from the US $ 120,667 to the US $ 4280.9.

Conclusion:

The results show that despite the high effectiveness of multifactorial interventions to prevent elderly falls, the cost of the interventions are high and they are not very cost-effective. It would be better to design and implement multifactorial interventions with low cost and high effectiveness that are appropriate for each country.

Costs and benefits of multifactorial falls prevention in nursing homes in the Netherlands

OBJECTIVES

To investigate whether the implementation of a multifactorial falls intervention in nursing homes is cost-beneficial and alleviates the professional workload.

DESIGN

A comprehensive quantitative model was developed to calculate the impact of investments in multifactorial falls prevention in nursing homes in the Netherlands, comparing the fall incidence using intervention strategies in 1000 nursing home residents with the conditions of usual care over a five-year timeline.

SETTING AND PARTICIPANTS

We built a model combining several data sources regarding falls and injury prevalence in nursing home residents, health care costs, intervention costs and effectiveness, and demographic statistics.

MEASURES

The primary outcomes were number of falls and injuries, treatment hours and cost.

RESULTS

In the nursing home setting, a baseline scenario was calculated with 1471 falls incidents resulting in 345 injuries per year. The mean cost of injury related treatment and care was calculated 860 thousand euro per year and €4.63 million in five years. Implementing multifactorial intervention over five years, costing 702 thousand euro, resulted in savings in health care costs of €2.0 million, of which €1.6 million was saved in nursing home injury care. The benefits outweighed the costs: each euro invested was compensated by 2.86 euro benefit in total care, 2.31 benefit in nursing home care. Yearly 3050 nursing hours, 3100 paramedical care hours and 760 h of physician care were saved.

CONCLUSION AND IMPLICATIONS

Implementation of customized multifactorial interventions provided by multidisciplinary teams is cost-beneficial in reduction of falls in nursing homes. The CBA model gives valuable information about the advantageous consequences (i.e. health benefits, financial benefits and reduced workload of staff) of falls prevention in nursing homes and can provide guidance to the management in structural implementation of multifactorial falls prevention.

Systematic review of unintentional injury prevention economic evaluations 2010-2019 and comparison to 1998-2009

BACKGROUND

Health economic evaluation studies (e.g., cost-effectiveness analysis) can provide insight into which injury prevention interventions maximize available resources to improve health outcomes. A previous systematic review summarized 48 unintentional injury prevention economic evaluations published during 1998-2009, providing a valuable overview of that evidence for researchers and decisionmakers. The aim of this study was to summarize the content and quality of recent (2010-2019) economic evaluations of unintentional injury prevention interventions and compare to the previous publication period (1998-2009).

METHODS

Peer-reviewed English-language journal articles describing public health unintentional injury prevention economic evaluations published January 1, 2010 to December 31, 2019 were identified using index terms in multiple databases. Injury causes, interventions, study methods, and results were summarized. Reporting on key methods elements (e.g., economic perspective, time horizon, discounting, currency year, etc.) was assessed. Reporting quality was compared between the recent and previous publication periods.

RESULTS

Sixty-eight recent economic evaluation studies were assessed. Consistent with the systematic review on this topic for the previous publication period, falls and motor vehicle traffic injury prevention were the most common study subjects. Just half of studies from the recent publication period reported all key methods elements, although this represents an improvement compared to the previous publication period (25 %).

CONCLUSION

Most economic evaluations of unintentional injury prevention interventions address just two injury causes. Better adherence to health economic evaluation reporting standards may enhance comparability across studies and increase the likelihood that this type of evidence is included in decision-making related to unintentional injury prevention.

Hip protectors are cost-effective in the prevention of hip fractures in patients with high fracture risk

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.

Economic Evaluations of Falls Prevention Programs for Older Adults: A Systematic Review

OBJECTIVES

To provide a comprehensive overview of economic evaluations of falls prevention programs and to evaluate the methodology and quality of these studies.

DESIGN

Systematic review of economic evaluations on falls prevention programs.

SETTING

Studies (N=31) of community-dwelling older adults (n=25), of older adults living in residential care facilities (n=3), and of both populations (n=3) published before May 2017.

PARTICIPANTS

Adults aged 60 and older.

MEASUREMENTS

Information on study characteristics and health economics was collected. Study quality was appraised using the 20-item Consensus on Health Economic Criteria.

RESULTS

Economic evaluations of falls prevention through exercise (n = 9), home assessment (n = 6), medication adjustment (n = 4), multifactorial programs (n = 11), and various other programs (n = 13) were identified. Approximately two-thirds of all reported incremental cost-effectiveness ratios (ICERs) with quality-adjusted life-years (QALYs) as outcome were below the willingness-to-pay threshold of $50,000 per QALY. All studies on home assessment and medication adjustment programs reported favorable ICERs, whereas the results of studies on exercise and multifactorial programs were inconsistent. The overall methodological quality of the studies was good, although there was variation between studies.

CONCLUSION

The majority of the reported ICERs indicated that falls prevention programs were cost-effective, but methodological differences between studies hampered direct comparison of the cost-effectiveness of program types. The results imply that investing in falls prevention programs for adults aged 60 and older is cost-effective. Home assessment programs (ICERs < $40,000/QALY) were the most cost-effective type of program for community-dwelling older adults, and medication adjustment programs (ICERs < $13,000/QALY) were the most cost-effective type of program for older adults living in a residential care facility.

Economic evaluation of health promotion interventions for older people: do applied economic studies meet the methodological challenges?

BACKGROUND

In the light of demographic developments health promotion interventions for older people are gaining importance. In addition to methodological challenges arising from the economic evaluation of health promotion interventions in general, there are specific methodological problems for the particular target group of older people. There are especially four main methodological challenges that are discussed in the literature. They concern measurement and valuation of informal caregiving, accounting for productivity costs, effects of unrelated cost in added life years and the inclusion of 'beyond-health' benefits. This paper focuses on the question whether and to what extent specific methodological requirements are actually met in applied health economic evaluations.

METHODS

Following a systematic review of pertinent health economic evaluations, the included studies are analysed on the basis of four assessment criteria that are derived from methodological debates on the economic evaluation of health promotion interventions in general and economic evaluations targeting older people in particular.

RESULTS

Of the 37 studies included in the systematic review, only very few include cost and outcome categories discussed as being of specific relevance to the assessment of health promotion interventions for older people. The few studies that consider these aspects use very heterogeneous methods, thus there is no common methodological standard.

CONCLUSION

There is a strong need for the development of guidelines to achieve better comparability and to include cost categories and outcomes that are relevant for older people. Disregarding these methodological obstacles could implicitly lead to discrimination against the elderly in terms of health promotion and disease prevention and, hence, an age-based rationing of public health care.

Advancing aged care: a systematic review of economic evaluations of workforce structures and care processes in a residential care setting

Long-term care for older people is provided in both residential and non-residential settings, with residential settings tending to cater for individuals with higher care needs. Evidence relating to the costs and effectiveness of different workforce structures and care processes is important to facilitate the future planning of residential aged care services to promote high quality care and to enhance the quality of life of individuals living in residential care. A systematic review conducted up to December 2015 identified 19 studies containing an economic component; seven included a complete economic evaluation and 12 contained a cost analysis only. Key findings include the potential to create cost savings from a societal perspective through enhanced staffing levels and quality improvement interventions within residential aged care facilities, while integrated care models, including the integration of health disciplines and the integration between residents and care staff, were shown to have limited cost-saving potential. Six of the 19 identified studies examined dementia-specific structures and processes, in which person-centred interventions demonstrated the potential to reduce agitation and improve residents’ quality of life. Importantly, this review highlights methodological limitations in the existing evidence and an urgent need for future research to identify appropriate and meaningful outcome measures that can be used at a service planning level.

Cost-effectiveness of hip protector use on a geriatric ward in Germany: a Markov model

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.

Physical activity in Iranian older adults who experienced fall during the past 12 months

Background

Physical activity may have several benefits for elderly people. However, the risk of falling might prevent this population from showing interest in physical activity. This research was aimed to explore facilitators and barriers to physical activity in older persons who have experienced at least one fall in the past 12 months.

Methods

This cross sectional study was conducted in 2010-2011, in Tehran, Iran. Using a multistage sampling method a group of elderly people entered into the study. A multi-section questionnaire was used to collect data on demographic information, physical activity level, and different determinants that might influence physical activity. Several statistical tests including linear regression were used to analyze the data.

Results

In all, 180 old people from 40 elderly centers (49 men and 131 women) took part in the study. The mean age of participants was 65.9 ± 6.1 years. The result indicated that most participants experienced two or more falls during the last year (54.5%). Those who had more falls significantly scored lower on the Physical Activity Scale for Elderly (p < 0.0001). ‘Keeping in touch with friends’ was the most important advantage cited by participants for performing physical activity. The results obtained from linear regression analysis showed that ‘perceived benefits’ was the only significant factor that associated with physical activity (β = 1.03, p < 0.001).

Conclusion

The findings suggest that perceived benefits could facilitate physical activity among elderly regardless of number of falls, self-reported health and daily living activities. However, we observed inverse association between number of falls and physical activity. Indeed the findings suggest that we should reinforce benefits exist when designing programs to increase physical activity among elderly population.
