Lack of effectiveness of a multidisciplinary fall-prevention program in elderly people at risk: a randomized, controlled trial

RESPOND--A patient-centred programme to prevent secondary falls in older people presenting to the emergency department with a fall: protocol for a multicentre randomised controlled trial

INTRODUCTION

Participation in falls prevention activities by older people following presentation to the emergency department (ED) with a fall is suboptimal. This randomised controlled trial (RCT) will test the RESPOND programme, an intervention designed to improve older persons' participation in falls prevention activities through delivery of patient-centred education and behaviour change strategies.

DESIGN AND SETTING

A RCT at two tertiary referral EDs in Melbourne and Perth, Australia.

PARTICIPANTS

528 community-dwelling people aged 60-90 years presenting to the ED with a fall and discharged home will be recruited. People who require an interpreter or hands-on assistance to walk; live in residential aged care or >50 km from the trial hospital; have terminal illness, cognitive impairment, documented aggressive behaviour or a history of psychosis; are receiving palliative care or are unable to use a telephone will be excluded.

METHODS

Participants will be randomly allocated to the RESPOND intervention or standard care control group. RESPOND incorporates (1) a home-based risk factor assessment; (2) education, coaching, goal setting and follow-up telephone support for management of one or more of four risk factors with evidence of effective interventions and (3) healthcare provider communication and community linkage delivered over 6 months. Primary outcomes are falls and fall injuries per person-year.

DISCUSSION

RESPOND builds on prior falls prevention learnings and aims to help individuals make guided decisions about how they will manage their falls risk. Patient-centred models have been successfully trialled in chronic and cardiovascular disease; however, evidence to support this approach in falls prevention is limited.

TRIAL REGISTRATION NUMBER

The protocol for this study is registered with the Australian New Zealand Clinical Trials Registry (ACTRN12614000336684).

Implementing person-environment approaches to prevent falls: a qualitative inquiry in applying the Westmead approach to occupational therapy home visits

BACKGROUND/AIMS

Despite evidence of the effectiveness of home safety interventions for preventing falls, there is limited uptake of such interventions within community services. Therefore, as part of a broader translational project, we explored issues underlying the implementation of an evidence-based home safety fall prevention intervention.

METHOD

We conducted in-depth interviews with eight occupational therapists and two programme coordinators engaged to deliver a home safety fall prevention intervention. Six community health centres within two metropolitan regions of Melbourne, Australia participated. The RE-AIM framework and Diffusion of Innovations theory underpinned the interviews which examine the enablers and barriers to implementing a home safety fall prevention intervention and integrating it into routine community preventive practice. Analysis involved thematic and content analysis.

RESULTS

Investment in the home safety for fall prevention intervention was supported and valued by coordinators and therapists alike, and a number of themes emerged which influenced implementation of this intervention. These included issues of: compatibility with organisational processes, individual practitioner practices and skills, a prevention approach, and client expectations; relative advantage in terms of flexibility of the process, client engagement and regional capacity building; complexity of implementing the intervention; and observability related to the invisible nature of fall prevention outcomes.

CONCLUSION

Implementation of this home safety fall prevention intervention was influenced by a range of interrelated organisational, practitioner and client related factors. The findings from this project provide insights into, and opportunities to increase the sustainable implementation of the home safety fall prevention intervention into practice.

Life-space mobility declines associated with incident falls and fractures

OBJECTIVES

To determine the effect of falls and fractures on life-space mobility in a cohort of community-dwelling older adults.

DESIGN

Prospective, observational study with a baseline in-home assessment and 6-month telephone follow-up interviews over 4 years.

SETTING

Central Alabama.

PARTICIPANTS

Community-dwelling adults aged 65 and older recruited from a random sample of Medicare beneficiaries stratified according to sex, race, and urban versus rural residence (N = 970).

MEASUREMENTS

Sociodemographic factors, medical history, depressive symptoms (Geriatric Depression Scale), cognitive function (Mini-Mental State Examination), mobility-related symptoms, transportation difficulty, and healthcare use were assessed during a baseline in-home interview of participants. Life-space mobility and falls or injuries (including fractures) were assessed at the baseline interview and at 6-month intervals in follow-up telephone calls.

RESULTS

Four hundred fifty-four (47%) participants reported at least one fall during the 4-year follow-up. The life-space score fell 3.2 points from the beginning to the end of the 6-month interval during which a fall occurred, adjusting for other known predictors of decline in life-space mobility. The decrease in interval life-space score was progressively greater for a fall and an injury (-4.7 points), a fall and a fracture (-14.2 points), and a fall and a hip fracture (-23.6 points).

CONCLUSION

Falls, whether associated with an injury or not, were independently associated with a decrease in life-space mobility in the ensuing 6 months. Further studies are needed to determine reasons for life-space mobility decline in community-dwelling older adults with incident falls without any injuries.

Preventive home visits for mortality, morbidity, and institutionalization in older adults: a systematic review and meta-analysis

BACKGROUND

Home visits for older adults aim to prevent cognitive and functional impairment, thus reducing institutionalization and mortality. Visitors may provide information, investigate untreated problems, encourage medication compliance, and provide referrals to services.

METHODS AND FINDINGS

DATA SOURCES

Ten databases including CENTRAL and Medline searched through December 2012.

STUDY SELECTION

Randomized controlled trials enrolling community-dwelling persons without dementia aged over 65 years. Interventions included visits at home by a health or social care professional that were not related to hospital discharge.

DATA EXTRACTION AND SYNTHESIS

Two authors independently extracted data. Outcomes were pooled using random effects.

MAIN OUTCOMES AND MEASURES

Mortality, institutionalization, hospitalization, falls, injuries, physical functioning, cognitive functioning, quality of life, and psychiatric illness.

RESULTS

Sixty-four studies with 28642 participants were included. Home visits were not associated with absolute reductions in mortality at longest follow-up, but some programs may have small relative effects (relative risk = 0.93 [0.87 to 0.99]; absolute risk = 0.00 [-0.01 to 0.00]). There was moderate quality evidence of no overall effect on the number of people institutionalized (RR = 1.02 [0.88 to 1.18]) or hospitalized (RR = 0.96 [0.91 to 1.01]). There was high quality evidence for number of people who fell, which is consistent with no effect or a small effect (odds ratio = 0.86 [0.73 to 1.01]), but there was no evidence that these interventions increased independent living. There was low and very low quality evidence of effects for quality of life (standardised mean difference = -0.06 [-0.11 to -0.01]) and physical functioning (SMD = -0.10 [-0.17 to -0.03]) respectively, but these may not be clinically important.

CONCLUSIONS

Home visiting is not consistently associated with differences in mortality or independent living, and investigations of heterogeneity did not identify any programs that are associated with consistent benefits. Due to poor reporting of intervention components and delivery, we cannot exclude the possibility that some programs may be effective.

Multifactorial assessment and targeted intervention to reduce falls among the oldest-old: a randomized controlled trial

Background

The purpose of this study was to assess the effectiveness of a multifactorial intervention to reduce falls among the oldest-old people, including individuals with cognitive impairment or comorbidities.

Methods

A randomized, single-blind, parallel-group clinical trial was conducted from January 2009 to December 2010 in seven primary health care centers in Baix Llobregat (Barcelona). Of 696 referred people who were born in 1924, 328 were randomized to an intervention group or a control group. The intervention model used an algorithm and was multifaceted for both patients and their primary care providers. Primary outcomes were risk of falling and time until falls. Data analyses were by intention-to-treat.

Results

Sixty-five (39.6%) subjects in the intervention group and 48 (29.3%) in the control group fell during follow-up. The difference in the risk of falls was not significant (relative risk 1.28, 95% confidence interval [CI] 0.94–1.75). Cox regression models with time from randomization to the first fall were not significant. Cox models for recurrent falls showed that intervention had a negative effect (hazard ratio [HR] 1.46, 95% CI 1.03–2.09) and that functional impairment (HR 1.42, 95% CI 0.97–2.12), previous falls (HR 1.09, 95% CI 0.74–1.60), and cognitive impairment (HR 1.08, 95% CI 0.72–1.60) had no effect on the assessment.

Conclusion

This multifactorial intervention among octogenarians, including individuals with cognitive impairment or comorbidities, did not result in a reduction in falls. A history of previous falls, disability, and cognitive impairment had no effect on the program among the community-dwelling subjects in this study.

Effectiveness of the Chaos Falls Clinic in preventing falls and injuries of home-dwelling older adults: a randomised controlled trial

BACKGROUND

Falls and related injuries are a major public health concern in elderly people. Multifactorial interventions may result in significant reduction in falls but their effectiveness in prevention of fall-induced injuries at centre-based falls clinics is unclear. This study assessed the effectiveness of the multifactorial Chaos Clinic Falls Prevention Programme on rate of falls and related injuries of home-dwelling older adults.

METHODS

This study was a pragmatic, randomised controlled trial concentrating on high risk individuals and their individual risk factors of falling. Home-dwelling elderly people aged 70 years or more were recruited to the Chaos falls clinics in the cities of Lappeenranta and Tampere in Finland between January 2005 and June 2009. 1314 participants with high-risk for falling and fall-induced injuries and fractures were randomised into intervention group (n=661) and control group (n=653). A multifactorial, individualized 12-month falls prevention programme concentrating on strength and balance training, medical review and referrals, medication review, proper nutrition (calcium, vitamin D), and home hazard assessment and modification was carried out in the intervention group. The main outcome measures were rates of falls, fallers, and fall-induced injuries.

RESULTS

During the one-year follow-up, 608 falls occurred in the intervention group and 825 falls in the control group. The rate of falls was significantly lower in the intervention group (95 falls per 100 person-years) than in the controls (131 falls per 100 person-years), the incidence rate ratio (IRR) being 0.72 (95% confidence interval (CI) 0.61-0.86, p<0.001, NNT 3). In the intervention group 296 participants fell at least once. In the controls the corresponding number was 349. The hazard ratio (HR) of fallers in the intervention group compared with the control group was 0.78 (95% CI 0.67-0.91, p=0.001, NNT 6). The number of fall-induced injuries in the intervention group was 351 with the corresponding rate (per 100 person-years) of 55. In the control group, these figures were higher, 468 and 75. The IRR of fall-induced injuries in the intervention group compared with the control group was 0.74 (95% CI 0.61-0.89, p=0.002, NNT 5).

CONCLUSIONS

The multifactorial Chaos Clinic Falls Prevention Programme is effective in preventing falls of older adults. The programme reduces the rate of falls and related injuries by almost 30%.

Effects of a complex intervention on fall risk in the general practitioner setting: a cluster randomized controlled trial

PURPOSE

To study the feasibility of first, reaching functionally declined, but still independent older persons at risk of falls through their general practitioner (GP) and second, to reduce their physiological and psychological fall risk factors with a complex exercise intervention. We investigated the effects of a 16-week exercise intervention on physiological (function, strength, and balance) and psychological (fear of falling) outcomes in community-dwelling older persons in comparison with usual care. In addition, we obtained data on adherence of the participants to the exercise program.

METHODS

Tests on physical and psychological fall risk were conducted at study inclusion, and after the 16-week intervention period in the GP office setting. The 16-week intervention included progressive and challenging balance, gait, and strength exercise as well as changes to behavioral aspects. To account for the hierarchical structure in the chosen study design, with patients nested in GPs and measurements nested in patients, a three-level linear mixed effects model was determined for analysis.

RESULTS

In total, 33 GPs recruited 378 participants (75.4% females). The mean age of the participants was 78.1 years (standard deviation 5.9 years). Patients in the intervention group showed an improvement in the Timed-Up-and-Go-test (TUG) that was 1.5 seconds greater than that showed by the control group, equivalent to a small to moderate effect. For balance, a relative improvement of 0.8 seconds was accomplished, and anxiety about falls was reduced by 3.7 points in the Falls Efficacy Scale-International (FES-I), in the intervention group relative to control group. In total, 76.6% (N = 170) of the intervention group participated in more than 75% the supervised group sessions.

CONCLUSION

The strategy to address older persons at high risk of falling in the GP setting with a complex exercise intervention was successful. In functionally declined, community-dwelling, older persons a complex intervention for reducing fall risks was effective compared with usual care.

Effects of interactive video-game based system exercise on the balance of the elderly

This study evaluated the effects of interactive video-game based (IVGB) training on the balance of older adults. The participants of the study included 30 community-living persons over the age of 65. The participants were divided into 2 groups. Group A underwent IVGB training for 6 weeks and received no intervention in the following 6 weeks. Group B received no intervention during the first 6 weeks and then participated in training in the following 6 weeks. After IVGB intervention, both groups showed improved balance based on the results from the following tests: the Berg Balance Scale (BBS), Modified Falls Efficacy Scale (MFES), Timed Up and Go (TUG) test, and the Sway Velocity (SV) test (assessing bipedal stance center pressure with eyes open and closed). Results from the Sway Area (SA) test (assessing bipedal stance center pressure with eyes open and closed) revealed a significant improvement in Group B after IVGB training. Group A retained some training effects after 6 weeks without IVGB intervention. Additionally, a moderate association emerged between the Xavix measured step system stepping tests and BBS, MFES, Unipedal Stance test, and TUG test measurements. In conclusion, IVGB training improves balance after 6 weeks of implementation, and the beneficial effects partially remain after training is complete. Further investigation is required to determine if this training is superior to traditional physical therapy.

Continuous versus Intermittent Data Collection of Health Care Utilization

Background: In economic evaluations, participants have to report their health care utilization continuously during follow-up. To unburden participants, researchers often collect data intermittently (i.e., in at least 3 months a year). However, comparability of intermittent v. continuous data collection is unknown. Therefore, this study aimed to compare costs estimated with intermittent data collection of health care utilization with those based on continuous data collection. Methods: We used continuous health care utilization data from a trial with 12 months of follow-up and simulated several intermittent data collection patterns. Then 3 imputation techniques—individual mean (IM), last observation carried forward (LOCF) and next observation carried backward (NOCB)—were used to estimate total annual costs. Estimated annual costs were compared with observed annual costs from continuous data collection both in the original sample and in 1000 bootstrap samples. Results: Analyses showed that intermittent data collection using cost diaries may offer good estimates of the actual total annual health expenditures. However, estimations of groups of costs differ between data collection patterns and imputation methods. The best estimations of annual total costs and groups of costs were obtained by random cohort data collection, using 3 random cohorts, ensuring that at least a third of the participants were measuring costs each month, combined with IM imputation. Intermittent data collection of health expenditures carries a small risk of missing infrequent expensive events. Conclusions: Continuous cost data collection remains the first choice. However, if intermittent measurement is chosen, we recommend calculating annual costs from intermittent data collection in random cohorts, combined with IM imputation.

The effectiveness of inter-professional working for older people living in the community: a systematic review

Health and social care policy in the UK advocates inter-professional working (IPW) to support older people with complex and multiple needs. Whilst there is a growing understanding of what supports IPW, there is a lack of evidence linking IPW to explicit outcomes for older people living in the community. This review aimed to identify the models of IPW that provide the strongest evidence base for practice with community dwelling older people. We searched electronic databases from 1 January 1990-31 March 2008. In December 2010 we updated the findings from relevant systematic reviews identified since 2008. We selected papers describing interventions that involved IPW for community dwelling older people and randomised controlled trials (RCT) reporting user-relevant outcomes. Included studies were classified by IPW models (Case Management, Collaboration and Integrated Team) and assessed for risk of bias. We conducted a narrative synthesis of the evidence according to the type of care (interventions delivering acute, chronic, palliative and preventive care) identified within each model of IPW. We retrieved 3211 records and included 37 RCTs which were mapped onto the IPW models: Overall, there is weak evidence of effectiveness and cost-effectiveness for IPW, although well-integrated and shared care models improved processes of care and have the potential to reduce hospital or nursing/care home use. Study quality varied considerably and high quality evaluations as well as observational studies are needed to identify the key components of effective IPW in relation to user-defined outcomes. Differences in local contexts raise questions about the applicability of the findings and their implications for practice. We need more information on the outcomes of the process of IPW and evaluations of the effectiveness of different configurations of health and social care professionals for the care of community dwelling older people.

Falling short: recruiting elderly individuals for a fall study

Despite the importance of movement and activity indicators in predicting the risk of falls in older adults, collection and analysis of such data are limited. The dearth may result from recruitment challenges faced by fall-related studies that capture data on movement and activity in older adults. This article addresses recruitment and sampling methodology issues and draws attention to the gap in best practices left by previous literature. Authors conducted a systematic review of methods used to recruit elderly individuals for "activity-related fall studies" that assessed subjects' movement and mobility, and investigated incidence of real falls. The review highlighted effective recruitment strategies and identified challenges across several settings. Literature review findings were compared to recruitment challenges encountered in an activity-related fall study from 2011, focused on enrolling a target group of older adults with both high risk of falling and the requisite cognitive capacity to adhere to activity protocols. The analysis yielded several recommendations for improving recruitment of older adults for activity-related fall studies, including: recruiting from community-based settings; utilizing short-term activity protocols to promote involvement among institutionalized elderly; establishing eligibility criteria that may include those with lower cognitive functioning, mobility restrictions, and co-morbidities; employing direct-mail recruitment methods; and utilizing intermediaries to recruit institutionalized elderly.

Characteristics of patients who stop falling after a risk-based multidisciplinary intervention initiated in a geriatric day hospital

BACKGROUND

Multidisciplinary interventions for fallers have provided conflicting results in part due to the diversity of fallers' profiles.

OBJECTIVES

to determine the characteristics of the subgroup of patients with a positive response to a multidisciplinary fall prevention program initiated in a geriatric day hospital.

DESIGN

Prospective observational study in day hospital.

METHODS

Patients > 75 years referred for falls during the last 3 months benefited from a multidisciplinary assessment to record their characteristics at baseline and to tailor a risk-based multidisciplinary intervention for fall prevention. Patients free from falls at the 3rd or 6th month were compared to persistent fallers for baseline characteristics.

RESULTS

Sixty-nine patients were assessed at baseline (mean age 85.2 y (SD=0.6)), 44 at the 3rd month and 21 at the 6th month. Baseline characteristics of the patients free from falls at the 3rd month were the lower number of previous non-serious falls (p=0.013), living in nursing home (p=0.045), a higher Berg balance score (p=0.02) and a better mental health-related quality of life (M HQol, p=0.045). On multivariate analysis restricted to home-dwelling patients, the positive predictive factors were less isolation at home (OR=0.028, 95%CI [0-0.813], p=0.037), a lower number of non-serious previous falls (OR= 0.526 [0.309- 0.894], p=0.018), a better M HQol (OR=1.205 [1.000-1.452], p=0.050) and a trend for younger age (OR= 0.662, [0.426-1.027], p=0.066).

CONCLUSION

Being able to call upon a support person (familial or institutional) to apply advice and a less serious risk of falling may be preliminary conditions for success in a multidisciplinary intervention initiated in a day hospital.

Effects of a multifactorial fall prevention program on fall incidence and physical function in community-dwelling older adults with risk of falls

OBJECTIVE

To evaluate effects of a multifactorial fall prevention program on fall incidence and physical function in community-dwelling older adults.

DESIGN

Multicenter randomized controlled trial.

SETTING

Three medical centers and adjacent community health centers.

PARTICIPANTS

Community-dwelling older adults (N=616) who have fallen in the previous year or are at risk of falling.

INTERVENTIONS

After baseline assessment, eligible subjects were randomly allocated into the intervention group (IG) or the control group (CG), stratified by the Physiological Profile Assessment (PPA) fall risk level. The IG received a 3-month multifactorial intervention program including 8 weeks of exercise training, health education, home hazards evaluation/modification, along with medication review and ophthalmology/other specialty consults. The CG received health education brochures, referrals, and recommendations without direct exercise intervention.

MAIN OUTCOME MEASURES

Primary outcome was fall incidence within 1 year. Secondary outcomes were PPA battery (overall fall risk index, vision, muscular strength, reaction time, balance, and proprioception), Timed Up & Go (TUG) test, Taiwan version of the International Physical Activity Questionnaire, EuroQol-5D, Geriatric Depression Scale (GDS), and the Falls Efficacy Scale-International at 3 months after randomization.

RESULTS

Participants were 76±7 years old and included low risk 25.6%, moderate risk 25.6%, and marked risk 48.7%. The cumulative 1-year fall incidence was 25.2% in the IG and 27.6% in the CG (hazard ratio=.90; 95% confidence interval, .66-1.23). The IG improved more favorably than the CG on overall PPA fall risk index, reaction time, postural sway with eyes open, TUG test, and GDS, especially for those with marked fall risk.

CONCLUSIONS

The multifactorial fall prevention program with exercise intervention improved functional performance at 3 months for community-dwelling older adults with risk of falls, but did not reduce falls at 1-year follow-up. Fall incidence might have been decreased simultaneously in both groups by heightened awareness engendered during assessments, education, referrals, and recommendations.

Fatal falls in an ethnically diverse urban community: the link between demographic factors and the circumstances surrounding fatal falls

OBJECTIVES

Fatal falls cause more than 15,000 deaths per year in the United States. Despite this, the circumstances surrounding fatal falls in elderly adults are poorly understood. It is unknown whether these circumstances differ across ethnicities, although Hispanic American individuals are at reduced risk for fatal falls. This study sought to describe fatal falls in an urban, predominantly Hispanic, and white non-Hispanic community and to determine the association of demographics with the circumstances surrounding these falls (proximate factors).

METHODS

The death certificates and medical examiners' reports for all 328 elderly individuals experiencing a fatal fall in Miami-Dade County, FL, from 2005 to 2007 were reviewed for demographic and proximate factors such as the preceding activity and fall location.

RESULTS

Fatal falls in elderly adults were experienced mostly by individuals living in the community (80%) and affected all demographic subgroups, although 80% occurred in individuals older than 74 years. Most fatal falls occurred at home (74%), indoors (75%), and during nonvigorous activities such as walking (58%) and these tended to affect the oldest elderly. In addition, a significant number of fatal falls occurred in public locations, outdoors, and during vigorous activity, with these falls tending to affect younger individuals living without family. Hispanic ethnicity was not associated with proximate factors.

CONCLUSIONS

Fatal fall prevention is needed for elderly individuals living in the community and should target the oldest elderly adults living at home while helping to ensure that individuals who are living without family have the appropriate support. These data suggest that Hispanic individuals may benefit from prevention strategies developed in other populations.

Interventions for preventing falls in older people living in the community

BACKGROUND

Approximately 30% of people over 65 years of age living in the community fall each year. This is an update of a Cochrane review first published in 2009.

OBJECTIVES

To assess the effects of interventions designed to reduce the incidence of falls in older people living in the community.

SEARCH METHODS

We searched the Cochrane Bone, Joint and Muscle Trauma Group Specialised Register (February 2012), CENTRAL (The Cochrane Library 2012, Issue 3), MEDLINE (1946 to March 2012), EMBASE (1947 to March 2012), CINAHL (1982 to February 2012), and online trial registers.

SELECTION CRITERIA

Randomised trials of interventions to reduce falls in community-dwelling older people.

DATA COLLECTION AND ANALYSIS

Two review authors independently assessed risk of bias and extracted data. We used a rate ratio (RaR) and 95% confidence interval (CI) to compare the rate of falls (e.g. falls per person year) between intervention and control groups. For risk of falling, we used a risk ratio (RR) and 95% CI based on the number of people falling (fallers) in each group. We pooled data where appropriate.

MAIN RESULTS

We included 159 trials with 79,193 participants. Most trials compared a fall prevention intervention with no intervention or an intervention not expected to reduce falls. The most common interventions tested were exercise as a single intervention (59 trials) and multifactorial programmes (40 trials). Sixty-two per cent (99/159) of trials were at low risk of bias for sequence generation, 60% for attrition bias for falls (66/110), 73% for attrition bias for fallers (96/131), and only 38% (60/159) for allocation concealment.Multiple-component group exercise significantly reduced rate of falls (RaR 0.71, 95% CI 0.63 to 0.82; 16 trials; 3622 participants) and risk of falling (RR 0.85, 95% CI 0.76 to 0.96; 22 trials; 5333 participants), as did multiple-component home-based exercise (RaR 0.68, 95% CI 0.58 to 0.80; seven trials; 951 participants and RR 0.78, 95% CI 0.64 to 0.94; six trials; 714 participants). For Tai Chi, the reduction in rate of falls bordered on statistical significance (RaR 0.72, 95% CI 0.52 to 1.00; five trials; 1563 participants) but Tai Chi did significantly reduce risk of falling (RR 0.71, 95% CI 0.57 to 0.87; six trials; 1625 participants).Multifactorial interventions, which include individual risk assessment, reduced rate of falls (RaR 0.76, 95% CI 0.67 to 0.86; 19 trials; 9503 participants), but not risk of falling (RR 0.93, 95% CI 0.86 to 1.02; 34 trials; 13,617 participants).Overall, vitamin D did not reduce rate of falls (RaR 1.00, 95% CI 0.90 to 1.11; seven trials; 9324 participants) or risk of falling (RR 0.96, 95% CI 0.89 to 1.03; 13 trials; 26,747 participants), but may do so in people with lower vitamin D levels before treatment.Home safety assessment and modification interventions were effective in reducing rate of falls (RR 0.81, 95% CI 0.68 to 0.97; six trials; 4208 participants) and risk of falling (RR 0.88, 95% CI 0.80 to 0.96; seven trials; 4051 participants). These interventions were more effective in people at higher risk of falling, including those with severe visual impairment. Home safety interventions appear to be more effective when delivered by an occupational therapist.An intervention to treat vision problems (616 participants) resulted in a significant increase in the rate of falls (RaR 1.57, 95% CI 1.19 to 2.06) and risk of falling (RR 1.54, 95% CI 1.24 to 1.91). When regular wearers of multifocal glasses (597 participants) were given single lens glasses, all falls and outside falls were significantly reduced in the subgroup that regularly took part in outside activities. Conversely, there was a significant increase in outside falls in intervention group participants who took part in little outside activity.Pacemakers reduced rate of falls in people with carotid sinus hypersensitivity (RaR 0.73, 95% CI 0.57 to 0.93; three trials; 349 participants) but not risk of falling. First eye cataract surgery in women reduced rate of falls (RaR 0.66, 95% CI 0.45 to 0.95; one trial; 306 participants), but second eye cataract surgery did not.Gradual withdrawal of psychotropic medication reduced rate of falls (RaR 0.34, 95% CI 0.16 to 0.73; one trial; 93 participants), but not risk of falling. A prescribing modification programme for primary care physicians significantly reduced risk of falling (RR 0.61, 95% CI 0.41 to 0.91; one trial; 659 participants).An anti-slip shoe device reduced rate of falls in icy conditions (RaR 0.42, 95% CI 0.22 to 0.78; one trial; 109 participants). One trial (305 participants) comparing multifaceted podiatry including foot and ankle exercises with standard podiatry in people with disabling foot pain significantly reduced the rate of falls (RaR 0.64, 95% CI 0.45 to 0.91) but not the risk of falling.There is no evidence of effect for cognitive behavioural interventions on rate of falls (RaR 1.00, 95% CI 0.37 to 2.72; one trial; 120 participants) or risk of falling (RR 1.11, 95% CI 0.80 to 1.54; two trials; 350 participants).Trials testing interventions to increase knowledge/educate about fall prevention alone did not significantly reduce the rate of falls (RaR 0.33, 95% CI 0.09 to 1.20; one trial; 45 participants) or risk of falling (RR 0.88, 95% CI 0.75 to 1.03; four trials; 2555 participants).No conclusions can be drawn from the 47 trials reporting fall-related fractures.Thirteen trials provided a comprehensive economic evaluation. Three of these indicated cost savings for their interventions during the trial period: home-based exercise in over 80-year-olds, home safety assessment and modification in those with a previous fall, and one multifactorial programme targeting eight specific risk factors.

AUTHORS' CONCLUSIONS

Group and home-based exercise programmes, and home safety interventions reduce rate of falls and risk of falling.Multifactorial assessment and intervention programmes reduce rate of falls but not risk of falling; Tai Chi reduces risk of falling.Overall, vitamin D supplementation does not appear to reduce falls but may be effective in people who have lower vitamin D levels before treatment.

Definitions and methods of measuring and reporting on injurious falls in randomised controlled fall prevention trials: a systematic review

Background

The standardisation of the assessment methodology and case definition represents a major precondition for the comparison of study results and the conduction of meta-analyses. International guidelines provide recommendations for the standardisation of falls methodology; however, injurious falls have not been targeted. The aim of the present article was to review systematically the range of case definitions and methods used to measure and report on injurious falls in randomised controlled trials (RCTs) on fall prevention.

Methods

An electronic literature search of selected comprehensive databases was performed to identify injurious falls definitions in published trials. Inclusion criteria were: RCTs on falls prevention published in English, study population ≥ 65 years, definition of injurious falls as a study endpoint by using the terms "injuries" and "falls".

Results

The search yielded 2089 articles, 2048 were excluded according to defined inclusion criteria. Forty-one articles were included. The systematic analysis of the methodology applied in RCTs disclosed substantial variations in the definition and methods used to measure and document injurious falls. The limited standardisation hampered comparability of study results. Our results also highlight that studies which used a similar, standardised definition of injurious falls showed comparable outcomes.

Conclusions

No standard for defining, measuring, and documenting injurious falls could be identified among published RCTs. A standardised injurious falls definition enhances the comparability of study results as demonstrated by a subgroup of RCTs used a similar definition. Recommendations for standardising the methodology are given in the present review.

Occupational therapy in fall prevention: current evidence and future directions

Falls are a serious public health concern among older adults in the United States. Although many fall prevention recommendations exist, such as those published by the American Geriatrics Society (AGS) and the British Geriatrics Society (BGS) in 2010, the specific role of occupational therapy in these efforts is unclear. This article presents a scoping review of current published research documenting the role of occupational therapy in fall prevention interventions among community-dwelling older adults, structured by the AGS and BGS guidelines. We identified evidence for occupational therapy practitioner involvement in fall prevention in environmental modifications, exercise, and multifactorial and multicomponent interventions. Although research documenting the efficacy of occupational therapy interventions is identified as part of the Occupational Therapy Practice Framework: Domain and Process (2nd ed.; American Occupational Therapy Association, 2008), we identified little or no such research examining interventions to modify behaviors (e.g., fear of falling), manage postural hypotension, recommend appropriate footwear, and manage medications. Although occupational therapy is represented in the fall prevention research, the evidence for the profession's role in many areas is still lacking.

Why older people refuse to participate in falls prevention trials: a qualitative study

BACKGROUND/OBJECTIVES

Falls are a major public health problem. Older persons are frequently underrepresented in trials, including falls prevention trials. Insight into possible reasons for non-participation could help to improve trial designs and participation rates among this age-group. The aim of this study was to explore reasons why older people refuse to participate in falls prevention trials.

SETTING

A qualitative study.

PARTICIPANTS

Community-dwelling adults aged ≥65 years who attended the Emergency Department due to a fall and refused to participate in a falls prevention trial (IMPROveFALL-study).

MEASUREMENTS

A structured interview guide was used, and interview transcripts were subjected to an independent content analysis by two researchers.

RESULTS

15 interviews were conducted. A main reason to refuse trial participation was mobility impairment. In contrast, younger and more "active" and mobile seniors considered themselves "too healthy" to participate. Persons with multiple comorbidities mentioned that they attended a hospital too often, or experienced adequate follow-up by their own physicians already. Transport problems, including distance to the hospital, parking facilities, and travel expenses were another issue. During the interviews it was emphasized by the patients, that they knew the reason for their fall. However, they were not familiar with the positive effects of falls prevention programmes.

CONCLUSIONS

Older persons reported multiple reasons to refuse participation in a falls prevention study, such as health-related factors, several practical problems, and personal beliefs about the causes and preventability of falls. Anticipation of those issues might contribute to an improvement in participation rates of older fallers, shorter study duration, and a better generalizability of research findings.

Hip fracture management, before and beyond surgery and medication: a synthesis of the evidence

INTRODUCTION

The geriatrician and orthopedic surgeon's roles are well defined in hip fracture management, yet other health-care providers contribute significantly toward care, as well as maximizing rehabilitation potential and decreasing readmissions. We examine evidence concerning pre-hospital care, pain management, multidisciplinary rehabilitation and secondary prevention strategies.

METHODS

Cochrane reviews and randomized controlled trials were identified through PubMed to synthesize current evidence in the role of multidisciplinary management of the patient with a hip fracture from injury to secondary prevention. The well-recognized roles of the geriatrician, anesthetist and orthopedic surgeon were not evaluated for the purpose of this review.

RESULTS

Transport of patients with a hip fracture can be eased through non-pharmaceutical simple, inexpensive techniques. Nerve blockade appears effective and easily administered in the emergency department. In-hospital multidisciplinary rehabilitation programs are effective in both earlier discharge and reducing falls, morbidity and mortality. Fall prevention programs are effective in nursing home patients, but not community dwellers. Osteoporosis prevention is primarily a medical endeavor; however, exercise and education may contribute to increased bone mineral density, compliance and better results of treatment.

CONCLUSION

Multidisciplinary medical management of patients with hip fractures is being improved within the hospital environment resulting in earlier discharge with decreased morbidity. There is evidence to show the benefits to patients with hip fractures from peripheral modalities within the hospital; however unless resident in a facility, multidisciplinary management is not clearly of benefit.

The interplay between gait, falls and cognition: can cognitive therapy reduce fall risk?

In this article, we briefly summarize the incidence and significant consequences of falls among older adults, the insufficient effectiveness of commonly used multifactorial interventions and the evidence linking falls and cognitive function. Recent pharmacologic and nonpharmacologic studies that evaluated the effects of cognitive therapy on fall risk are reviewed. The results of this article illustrate the potential utility of multiple, diverse forms of cognitive therapy for reducing fall risk. The article also indicates that large-scale, randomized controlled trials are warranted and that additional research is needed to better understand the pathophysiologic mechanisms underlying the interplay between human mobility, fall risk and cognitive function. Nonetheless, we suggest that multimodality interventions that combine motor and cognitive therapy should, eventually, be incorporated into clinical practice to enable older adults and patients to move safer and with a reduced fall risk.

[The effectiveness of falls clinics in the Netherlands]

Recently, two articles are published about the effectiveness of a multifactorial fall prevention programme performed by two falls clinics in the Netherlands. Both studies have shown negative results. The question is if those two studies are representative for the real situation in most falls clinics in the Netherlands. Two important differences are the selection of the patients and the completion of the fall prevention program. It is important to select the patients with the highest fall risk (> or = 2 falls/year and/or > or = 4 fall risk factors) and to provide an active and direct management of the identified fall risk factors to improve the effectiveness of falls clinics.

Multifactorial evaluation and treatment of persons with a high risk of recurrent falling was not cost-effective

SUMMARY

This study evaluated the cost-effectiveness of multifactorial evaluation and treatment of fall risk factors in community-dwelling older persons at high risk of falling. The intervention and usual care groups did not differ in fall risk or costs. The multifactorial approach was not cost-effective compared to usual care in this group.

INTRODUCTION

International guidelines recommend multifactorial evaluation and tailored treatment of risk factors to reduce falling in older persons. The cost-effectiveness may be enhanced in high-risk persons. Our study evaluates the cost-effectiveness of multifactorial evaluation and treatment of fall risk factors in community-dwelling older persons at high risk of recurrent falling.

METHODS

An economic evaluation was conducted alongside a randomised controlled trial. Participants (≥65 years) with a high risk of recurrent falling were randomised into an intervention (n = 106) and usual care group (n = 111). The intervention consisted of multifactorial assessment and treatment of fall risk factors. Clinical outcomes were proportions of fallers and utility during 1 year. Costs were measured using questionnaires at 3, 6 and 12 months after baseline and valued using cost prices, if available, and guideline prices. Differences in costs and cost-effectiveness were analysed using bootstrapping. Cost-effectiveness planes and acceptability curves were presented.

RESULTS

During 1 year, 52% and 56% of intervention and usual care participants reported at least one fall, respectively. The clinical outcome measures did not differ between the two groups. The mean costs were Euro 7,740 (SD 9,129) in the intervention group and Euro 6,838 (SD 8,623) in the usual care group (mean difference Euro 902, bootstrapped 95% CI: -1,534 to 3,357). Cost-effectiveness planes and acceptability curves indicated that multifactorial evaluation and treatment of fall risk factors was not cost-effective compared with usual care.

CONCLUSIONS

Multifactorial evaluation and treatment of persons with a high risk of recurrent falling was not cost-effective compared to usual care.

High yield research opportunities in geriatric emergency medicine: prehospital care, delirium, adverse drug events, and falls

Emergency services constitute crucial and frequently used safety nets for older persons, an emergency visit by a senior very often indicates high vulnerability for functional decline and death, and interventions via the emergency system have significant opportunities to change the clinical course of older patients who require its services. However, the evidence base for widespread employment of emergency system-based interventions is lacking. In this article, we review the evidence and offer crucial research questions to capitalize on the opportunity to optimize health trajectories of older persons seeking emergency care in four areas: prehospital care, delirium, adverse drug events, and falls.

Effectiveness of intervention programs in preventing falls: a systematic review of recent 10 years and meta-analysis

OBJECTIVE

To examine the reported effectiveness of fall-prevention programs for older adults by reviewing randomized controlled trials from 2000 to 2009.

DESIGN

Systematic review and meta-analysis of randomized controlled trials.

DATA SOURCES

A systematic literature search of articles was conducted using 5 electronic databases (Medline, PubMed, PsycINFO, CINAHL, and RefWorks), including articles describing interventions designed to prevent falls, in English with full text availability, from 2000 through 2009.

REVIEW METHODS

Of a potential 227 studies, we identified 17 randomized controlled trials with a duration of intervention of at least 5 months of follow-up. Inclusion and exclusion criteria were used to assess the methodological qualities of the studies. We excluded unidentified study design, quasi-experimental studies, and/or studies that were nonspecific regarding inclusion criteria.

DATA EXTRACTION

Primary outcome measures were number of falls and fall rate. Methodological quality assessment included internal and external validity, reporting, and power. Data were extracted independently by 2 investigators and analyzed using a random-effects model. We analyzed the effectiveness of these fall intervention programs using their risk ratios (RR) in 2 single-intervention versus 15 multifactorial intervention trials, 3 nursing homes versus 14 community randomized controlled trials, and 8 Model 1 (initial intervention with subsequent follow up) versus 9 Model II (ongoing intervention throughout the follow-up) studies.

RESULTS

The combined RR for the number of falls among 17 studies was 0.855 (z = -2.168; p = .030; 95% CI = 0.742-0.985; Q = 196.204, df = 16, P = .000, I(2) = 91.845), demonstrating that fall-prevention programs across the studies were effective by reducing fall rates by 14%, but with substantial heterogeneity. Subgroup analysis indicated that there was a significant fall reduction of 14% in multifactorial intervention (RR = 0.856, z = -2.039, P = .041) with no variation between multifactorial and single-intervention groups (Q = 0.002, P = .961), 55% in the nursing home setting (RR = 0.453, z = -9.366, P = .000) with significant variation between nursing home and community groups (Q = 62.788, P = .000), and no significant effect was gained by dividing studies into either in Model I or II. Sensitivity analysis found homogeneity (Q = 18.582, df = 12, P = .099, I(2) = 35.423) across studies with a 9% overall fall reduction (RR = 0.906, 95% CI = 0.853-0.963, z = -3.179, P = .001), including a fall-reduction rate of 10% in multifactorial intervention (RR = 0.904, z = -3.036, P = .002), 9% in community (RR = 0.909, z = -3.179, P = .001), and 12% in Model I (RR = 0.876, z = -3.534, P = .000) with no variations among all the groups. Meta regression suggested that the model fit explained 68.6% of the relevant variance.

CONCLUSIONS

The meta-sensitivity analysis indicates that randomized controlled trials of fall-prevention programs conducted within the past 10 years (2000-2009) are effective in overall reduction of fall rates of 9% with a reduction of fall rates of 10% in multifactorial interventions, 9% in community settings, and 12% in Model I interventions (initial intervention efforts and then subsequent follow-up).

Attempts to reach the oldest and frailest: recruitment, adherence, and retention of urban elderly persons to a falls reduction exercise program

PURPOSE OF THE STUDY

To assess the recruitment, adherence, and retention of urban elderly, predominantly African Americans to a falls reduction exercise program.

DESIGN AND METHODS

The randomized controlled trial was designed as an intervention development pilot study. The goal was to develop a culturally sensitive intervention for elderly persons who suffered a fall and visited an emergency department (ED). Participants were taught exercises during 4 on-site group classes and encouraged to continue exercising at home for 12 weeks and attend additional on-site monthly classes. The protocol included a specifically designed intervention for increasing retention through trained community interventionists drawn from the participants' neighborhoods.

RESULTS

The screening of 1,521 ED records after falling yielded the recruitment of 204 patients aged 65 years and older. Half were randomized into the falls prevention program. Of the 102 people in the intervention group, 92 completed the final 6-month assessment, 68 attended all on-site sessions, but only 1 reported exercising at home all 12 weeks. Those who lived alone were more likely (p = .03) and those with symptoms of depression were less likely (p = .05) to attend all on-site exercise classes. The final recruitment rate was estimated as 31.8%. The final retention rates were 90.2% and 87.3% for the intervention and control groups, respectively.

IMPLICATIONS

Recruitment of frail elderly African American patients is resource intensive. Adherence to the on-site exercise classes was better than to the home-based component of the program. These findings have implications for the design of future community-based exercise programs and trials.

Research priorities for high-quality geriatric emergency care: medication management, screening, and prevention and functional assessment

BACKGROUND

Geriatric adults represent an increasing proportion of emergency department (ED) users and can be particularly vulnerable to acute illnesses. Health care providers have recently begun to focus on the development of quality indicators (QIs) to define a minimal standard of care.

OBJECTIVES

The original objective of this project was to develop additional ED-specific QIs for older patients within the domains of medication management, screening and prevention, and functional assessment, but the quantity and quality of evidence were insufficient to justify unequivocal minimal standards of care for these three domains. Accordingly, the authors modified the project objectives to identify key research opportunities within these three domains that can be used to develop QIs in the future.

METHODS

Each domain was assigned one or two content experts who created potential QIs based on a systematic review of the literature, supplemented by expert opinion. Candidate QIs were then reviewed by four groups: the Society for Academic Emergency Medicine (SAEM) Geriatric Task Force, the SAEM Geriatric Interest Group, and audiences at the 2008 SAEM Annual Meeting and the 2009 American Geriatrics Society Annual Meeting, using anonymous audience response system technology as well as verbal and written feedback.

RESULTS

High-quality evidence based on patient-oriented outcomes was insufficient or nonexistent for all three domains. The participatory audiences did not reach a consensus on any of the proposed QIs. Key research questions for medication management (three), screening and prevention (two), and functional assessment (three) are presented based on proposed QIs that the majority of participants accepted.

CONCLUSIONS

In assessing a minimal standard of care by which to systematically derive geriatric QIs for medication management, screening and prevention, and functional assessment, compelling clinical research evidence is lacking. Patient-oriented research questions that are essential to justify and characterize future QIs within these domains are described.

Formative evaluation of the telecare fall prevention project for older veterans

Background

Fall prevention interventions for community-dwelling older adults have been found to reduce falls in some research studies. However, wider implementation of fall prevention activities in routine care has yielded mixed results. We implemented a theory-driven program to improve care for falls at our Veterans Affairs healthcare facility. The first project arising from this program used a nurse advice telephone line to identify patients' risk factors for falls and to triage patients to appropriate services. Here we report the formative evaluation of this project.

Methods

To evaluate the intervention we: 1) interviewed patient and employee stakeholders, 2) reviewed participating patients' electronic health record data and 3) abstracted information from meeting minutes. We describe the implementation process, including whether the project was implemented according to plan; identify barriers and facilitators to implementation; and assess the incremental benefit to the quality of health care for fall prevention received by patients in the project. We also estimate the cost of developing the pilot project.

Results

The project underwent multiple changes over its life span, including the addition of an option to mail patients educational materials about falls. During the project's lifespan, 113 patients were considered for inclusion and 35 participated. Patient and employee interviews suggested support for the project, but revealed that transportation to medical care was a major barrier in following up on fall risks identified by nurse telephone triage. Medical record review showed that the project enhanced usual medical care with respect to home safety counseling. We discontinued the program after 18 months due to staffing limitations and competing priorities. We estimated a cost of $9194 for meeting time to develop the project.

Conclusions

The project appeared feasible at its outset but could not be sustained past the first cycle of evaluation due to insufficient resources and a waning of local leadership support due to competing national priorities. Future projects will need both front-level staff commitment and prolonged high-level leadership involvement to thrive.

Hispanic ethnicity and fatal fall risk: do age, gender, and community modify the relationship?

BACKGROUND

Hispanic ethnicity is associated with a reduced risk of fatal falls in the elderly despite lower socioeconomic standing. The factors responsible for this "Hispanic paradox" are unknown. We hypothesized that age and gender would modify this relationship and that the association would be accentuated in a community with prominent Hispanic culture.

MATERIALS AND METHODS

The number of fatal falls in a 3-year period in the United States (US) and in Miami-Dade County, Florida (MDC) were obtained through the CDC's WISQARS database and the Florida Office of Vital Statistics. US Census Bureau data were used to define the total at-risk populations by age group and gender. Age group- and gender-specific ratios of the risk of fatal fall in Hispanic to white non-Hispanic individuals were calculated.

RESULTS

In the US and MDC, Hispanic ethnicity was associated with a reduced risk of fatal fall across all age and gender subgroups. In the US, the risk reduction associated with Hispanic ethnicity grew from 11% and 23% in 65- to 74-year-old men and women, respectively, to 43% for both men and women over 84-years-old. This relationship was stronger in MDC than nationally in five of the six age and gender subgroups examined.

CONCLUSIONS

Older individuals, women, and residents of communities with prominent Hispanic culture have the greatest reduction in fatal fall risk associated with Hispanic ethnicity.

Modification of the home environment for the reduction of injuries

BACKGROUND

Injury in the home is common, accounting for approximately a third of all injuries. The majority of injuries to children under five and people aged 75 and older occur at home. Multifactorial injury prevention interventions have been shown to reduce injuries in the home. However, few studies have focused specifically on the impact of physical adaptations to the home environment and the effectiveness of such interventions needs to be ascertained.

OBJECTIVES

To determine the effect of modifications to the home environment on the reduction of injuries due to environmental hazards.

SEARCH STRATEGY

We searched The Cochrane Library, MEDLINE, EMBASE and other specialised databases. We also scanned conference proceedings and reference lists. We contacted the first author of all included randomised controlled trials. The searches were last updated to the end of December 2009, and were not restricted by language or publication status.

SELECTION CRITERIA

Randomised controlled trials.

DATA COLLECTION AND ANALYSIS

Two authors screened all abstracts for relevance, outcome and design. Two authors independently assessed methodological quality and extracted data from each eligible study. We performed meta-analysis to combine effect measures, using a random-effects model. We assessed heterogeneity using an I(2) statistic and a Chi(2) test.

MAIN RESULTS

We found 28 published studies and one unpublished study. Only two studies were sufficiently similar to allow pooling of data for statistical analyses. Studies were divided into three groups; children, older people and the general population/mixed age group. None of the studies focusing on children or older people demonstrated a reduction in injuries that were a direct result of environmental modification in the home. One study in older people demonstrated a reduction in falls and one a reduction in falls and injurious falls that may have been due to hazard reduction. One meta-analysis was performed which examined the effects on falls of multifactorial interventions consisting of home hazard assessment and modification, medication review, health and bone assessment and exercise (RR 1.09, 95% CI 0.97 to 1.23).

AUTHORS' CONCLUSIONS

There is insufficient evidence to determine whether interventions focused on modifying environmental home hazards reduce injuries. Further interventions to reduce hazards in the home should be evaluated by adequately designed randomised controlled trials measuring injury outcomes. Recruitment of large study samples to measure effect must be a major consideration for future trials. Researchers should also consider using factorial designs to allow the evaluation of individual components of multifactorial interventions.

Comparison of different strategies of referral to a fall clinic: how to achieve an optimal casemix?

OBJECTIVE To study the potential differences in patient characteristics between two referral methods to a fall clinic, specifically: case-finding of patients admitted to an emergency department because of a fall, compared to direct referral to the fall clinic via the general practitioner.

DESIGN

Cross-sectional study.

SETTING

Fall clinics in two university teaching hospitals in the Netherlands.

PARTICIPANTS

Three hundred community-dwelling older people aged 65 years or over currently attending the fall clinics in Nijmegen (Group 1, n=154) and in Amsterdam (Group 2, n=146).

MEASUREMENTS

Patients were referred by a general practitioner (Group 1) or were selected using the Carefall Triage Instrument (CTI) after visiting the emergency department (Group 2). In all patients, modifiable risk factors for recurrent falls were assessed.

RESULTS

Group 1 had less modifiable risk factors for falling (a mean of 4 (SD 1.6) vs. a mean of 5 (SD 1.5) in Group 2, p < 0.001). Compared to Group 2, Group 1 had more prevalent " recurrent falling (≥ 2 falls)" (p=0.001) and "assisted living in homes for the aged" (p=0.037). "Fear of falling", "mobility and balance problems", "home hazards" and "osteoporosis" were significantly less prevalent in Group 1.

CONCLUSION

This study suggests that patients referred to a multidisciplinary fall prevention clinic by their general practitioner have a different risk profile than those selected by case finding using the CTI. These differences have consequences for the reach of secondary care for fall-preventive interventions and will probably influence the effectiveness and efficiency of a fall prevention program.

Multifactorial fall prevention for pairs of frail community-dwelling older fallers and their informal caregivers: a dead end for complex interventions in the frailest fallers

OBJECTIVE

To assess whether a multifactorial fall prevention program was more effective than usual geriatric care in preventing falls and reducing fear of falling in frail community-dwelling older fallers, with and without cognitive impairment, and in alleviating subjective caregiver burden in caregivers.

DESIGN, SETTING, AND PARTICIPANTS

A randomized, 2 parallel-group, single-blind, multicenter trial conducted in 36 pairs of frail fallers, who were referred to a geriatric outpatient clinic after at least 1 fall in the past 6 months, and their informal caregivers.

INTERVENTION

Groups of 5 pairs of patients and caregivers received 10 twice-weekly, 2-hour sessions with physical and psychological components and a booster session.

MEASUREMENTS

The primary outcome was the fall rate during a 6-month follow-up. Additionally, we measured fear of falling and subjective caregiver burden. Data on the secondary outcome measures were collected at baseline, directly after, and at 3 and 6 months after the last session of the intervention.

RESULTS

Directly after the intervention and at the long-term evaluation, the rate of falls in the intervention group was higher than in the control group, although these differences were not statistically significant (RR = 7.97, P = .07 and RR = 2.12, P = .25, respectively). Fear of falling was higher in the intervention group, and subjective caregiver burden did not differ between groups.

CONCLUSION

Although we meticulously developed this pairwise multifactorial fall prevention program, it was not effective in reducing the fall rate or fear of falling and was not feasible for caregivers, as compared with regular geriatric care. Future research initiatives should be aimed at how to implement the evidence-based principles of geriatric fall prevention for all frail fallers rather than developing more complex interventions for the frailest.

Scales for assessing self-efficacy of nurses and assistants for preventing falls

AIM

This paper is a report of the development and testing of the Self-Efficacy for Preventing Falls Nurse and Assistant scales.

BACKGROUND

Patient falls and fall-related injuries are traumatic ordeals for patients, family members and providers, and carry a toll for hospitals. Self-efficacy is an important factor in determining actions persons take and levels of performance they achieve. Performance of individual caregivers is linked to the overall performance of hospitals. Scales to assess nurses and certified nursing assistants' self-efficacy to prevent patients from falling would allow for targeting resources to increase SE, resulting in improved individual performance and ultimately decreased numbers of patient falls.

METHOD

Four phases of instrument development were carried out to (1) generate individual items from eight focus groups (four each nurse and assistant conducted in October 2007), (2) develop prototype scales, (3) determine content validity during a second series of four nurse and assistant focus groups (January 2008) and (4) conduct item analysis, paired t-tests, Student's t-tests and internal consistency reliability to refine and confirm the scales. Data were collected during February-December, 2008.

RESULTS

The 11-item Self-Efficacy for Preventing Falls Nurse had an alpha of 0·89 with all items in the range criterion of 0·3-0·7 for item total correlation. The 8-item Self-Efficacy for Preventing Falls Assistant had an alpha of 0·74 and all items had item total correlations in the 0·3-0·7 range.

CONCLUSIONS

The Self-Efficacy for Preventing Falls Nurse and Self-Efficacy for Preventing Falls Assistant scales demonstrated psychometric adequacy and are recommended to measure bedside staff's self-efficacy beliefs in preventing patient falls.

Fall prevention in acute care hospitals: a randomized trial

CONTEXT

Falls cause injury and death for persons of all ages, but risk of falls increases markedly with age. Hospitalization further increases risk, yet no evidence exists to support short-stay hospital-based fall prevention strategies to reduce patient falls.

OBJECTIVE

To investigate whether a fall prevention tool kit (FPTK) using health information technology (HIT) decreases patient falls in hospitals.

DESIGN, SETTING, AND PATIENTS

Cluster randomized study conducted January 1, 2009, through June 30, 2009, comparing patient fall rates in 4 urban US hospitals in units that received usual care (4 units and 5104 patients) or the intervention (4 units and 5160 patients).

INTERVENTION

The FPTK integrated existing communication and workflow patterns into the HIT application. Based on a valid fall risk assessment scale completed by a nurse, the FPTK software tailored fall prevention interventions to address patients' specific determinants of fall risk. The FPTK produced bed posters composed of brief text with an accompanying icon, patient education handouts, and plans of care, all communicating patient-specific alerts to key stakeholders.

MAIN OUTCOME MEASURES

The primary outcome was patient falls per 1000 patient-days adjusted for site and patient care unit. A secondary outcome was fall-related injuries.

RESULTS

During the 6-month intervention period, the number of patients with falls differed between control (n = 87) and intervention (n = 67) units (P=.02). Site-adjusted fall rates were significantly higher in control units (4.18 [95% confidence interval {CI}, 3.45-5.06] per 1000 patient-days) than in intervention units (3.15 [95% CI, 2.54-3.90] per 1000 patient-days; P = .04). The FPTK was found to be particularly effective with patients aged 65 years or older (adjusted rate difference, 2.08 [95% CI, 0.61-3.56] per 1000 patient-days; P = .003). No significant effect was noted in fall-related injuries.

CONCLUSION

The use of a fall prevention tool kit in hospital units compared with usual care significantly reduced rate of falls.

TRIAL REGISTRATION

Relationship between location and activity in injurious falls: an exploratory study

Background

Knowledge about the circumstances under which injurious falls occur could provide healthcare workers with better tools to prevent falls and fall-related injuries. Therefore, we assessed whether older persons who sustain an injurious fall can be classified into specific fall types, based on a combination of fall location and activity up to the moment of the fall. In addition, we assessed whether specific injurious fall types are related to causes of the fall, consequences of the fall, socio-demographic characteristics, and health-related characteristics.

Methods

An exploratory, cross-sectional study design was used to identify injurious fall types. The study population comprised 333 community-dwelling Dutch elderly people aged 65 years or over who attended an accident and emergency department after a fall. All participants received a self-administered questionnaire after being discharged home. The questionnaire comprised items concerning circumstances of the injurious fall, causes of the fall, consequences of the fall, socio-demographic characteristics and health-related characteristics. Injurious fall types were distinguished by analyzing data by means of HOMALS (homogeneity analysis by means of alternating least squares).

Results

We identified 4 injurious fall types: 1) Indoor falls related to lavatory visits (hall and bathroom); 2) Indoor falls during other activities of daily living; 3) Outdoor falls near the home during instrumental activities of daily living; 4) Outdoor falls away from home, occurring during walking, cycling, and shopping for groceries. These injurious fall types were significantly related to age, cause of the fall, activity avoidance and daily functioning.

Conclusion

The face validity of the injurious fall typology is obvious. However, we found no relationship between the injurious fall types and severity of the consequences of the fall. Nevertheless, there appears to be a difference between the prevalence of fractures and the cause of the fall between the injurious fall types. Our data suggests that with regard to prevention of serious injuries, we should pay special attention to outdoor fallers and indoor fallers during lavatory visits. In addition, we should have special attention for causes of the fall. However, the conclusions reached in this exploratory analysis are tentative and need to be validated in a separate dataset.

Effect of a program of multifactorial fall prevention on health-related quality of life, functional ability, fear of falling and psychological well-being. A randomized controlled trial

BACKGROUND AND AIMS

Falls among older people are associated with injury, functional decline, fear of falling, and depression. This study aims to evaluate the effect of multifactorial fall prevention on function, fear of falling, health-related quality of life and psychological well-being.

METHODS

392 older people > or =65 years sustaining a fall, leading to treatment in the emergency room or hospitalization, were included in a randomized, controlled intervention study on multifactorial fall prevention. The intervention consisted of systematic assessment and personalized treatment aimed at reducing risk factors for falls, and was performed at the geriatric outpatient department of a university hospital. The control group received usual care. Outcome measures were functional ability (Barthel Index and Frenchay Activity Index), fear of falling (Activities Balance Confidence Scale), health-related quality of life (SF- 36), and psychological well-being (SCL-92), and were recorded at interviews 6 and 12 months after inclusion.

RESULTS

Only the physical function of SF-36 was slightly positively affected by the intervention (p=0.04). There were no effects on general health (p=0.49) or mental health (p=0.39) items, Barthel Index (p=0.10), Frenchay Activity Index (p=0.71), balance confidence (p=0.77), anxiety (p=0.92), depression (p=0.90) or somatization (p=0.13).

CONCLUSIONS

This program of multifactorial fall prevention may have an effect on the physical function item of health-related quality of life in favor of the intervention group, but none on other measures of health-related quality of life, daily function, fear of falling or psychological well-being.

Maintaining independence in older people

Appropriate social and medical interventions may help maintain independence in older people. Determinants of functional decline, disability and reduced independence are recognized and specific interventions target the treatment of clinical conditions, multiple health problems and geriatric conditions, prevention of falls and fractures, and maintenance of physical and cognitive function and social engagement.

Preventive strategies to identify and treat diverse unmet needs of older people have been researched extensively. We reviewed systematically recent randomized controlled trials evaluating these ‘complex’ interventions and incorporated the findings of 21 studies into an established meta-analysis that included 108,838 people in 110 trials. There was an overall benefit of complex interventions in helping older people to live at home, explained by reduced nursing home admissions rather than death rates. Hospital admissions and falls were also reduced in intervention groups. Benefits were largely restricted to earlier studies, perhaps reflecting general improvements in health and social care for older people. The wealth of high-quality trial evidence endorses the value of preventive strategies to help maintain independence in older people.

Care Management Service and Falls Prevention: A Case-Control Study in a Chinese Population

Objective: This study evaluates the effect of a care management service (CMS) on falls in older adults. Method: This is a retrospective case-control study with 78 CMS recipients as the case group who received CMS and another 312 community-dwelling frail elders as the control group.The groups were matched by age, gender, activity of daily living, cognitive impairment, and unsteady gait. Thus they were comparable in characteristics and frailty. Results: Among the 390 participants, 89 older adults (23.0%) had falls in the 90 days prior to the survey. After controlling for the identified risk factors for falls, the odds ratio of CMS was 0.27 (95% confidence interval = 0.110-0.663, p < .01). Discussion: These findings indicate that CMS recipients have a lower chance for falls compared to their counterparts. The two features of CMS (comprehensive assessment and multidisciplinary actions to reduce fall risks) are discussed.

Lessons learned from a multidisciplinary fall-prevention programme: the occupational-therapy element

OBJECTIVE

To gain insight into the contribution of the occupational-therapy part of a multidisciplinary fall prevention programme towards the reduction of falls and functional decline.

DESIGN

A descriptive and exploratory study.

METHODS

Data were collected in the context of a randomized controlled trial that found no effect of a multidisciplinary fall prevention programme. The study population comprised 166 participants, two occupational therapists (OTs), and one official from each of the five participating municipalities. Data were collected on the recommendations arising from the OT part of the programme, the extent to which those recommendations were implemented and what OTs did to stimulate implementation of behaviour change.

RESULTS

The occupational-therapy programme resulted in 457 recommendations; 65% of the recommendations regarding services and assistive devices were implemented. It took on average six months to implement recommended home modifications. Advice on behaviour change predominantly comprised recommendations to reduce risky behaviour.

CONCLUSION

To improve the occupational-therapy programme more rapid implementation of recommendations is suggested. Second, participants should be supported to achieve recommended changes. Furthermore, occupational therapists should use theory-based techniques to stimulate behaviour change and use follow-up visits to promote maintenance of the desired behaviour.

Evaluation and management of osteoporosis and fragility fractures in the elderly

Osteoporosis is characterized by low bone mass and microarchitectural deterioration that leads to increased bone fragility and fracture. The medical, psychosocial and economic burden that fragility fractures have on individuals and society is staggering. As the geriatric segment of the population continues to expand, so to will the magnitude of this epidemic. There are multiple mechanisms influencing bone quality and bone loss with age. Fragility fracture is a composite of multiple intrinsic and extrinsic factors related to the individual and their environment. Fall prevention remains the cornerstone of management in this problem. The FRAX® fracture risk assessment program, which estimates the 10-year probability of a major osteoporotic fracture, is an exciting new tool in assessing risk. Novel therapeutics, including zoledronic acid, strontium and teriparatide, are now available to complement proven osteoporosis treatments and more effectively decrease fracture risk in vulnerable individuals. Agents in Phase III trials, including denosumab and lasofoxifene, will probably increase the armamentarium of tools clinicians can use to combat the growing problem of osteoporosis and its complications.

Design of a continuous quality improvement program to prevent falls among community-dwelling older adults in an integrated healthcare system

Background

Implementing quality improvement programs that require behavior change on the part of health care professionals and patients has proven difficult in routine care. Significant randomized trial evidence supports creating fall prevention programs for community-dwelling older adults, but adoption in routine care has been limited. Nationally-collected data indicated that our local facility could improve its performance on fall prevention in community-dwelling older people. We sought to develop a sustainable local fall prevention program, using theory to guide program development.

Methods

We planned program development to include important stakeholders within our organization. The theory-derived plan consisted of 1) an initial leadership meeting to agree on whether creating a fall prevention program was a priority for the organization, 2) focus groups with patients and health care professionals to develop ideas for the program, 3) monthly workgroup meetings with representatives from key departments to develop a blueprint for the program, 4) a second leadership meeting to confirm that the blueprint developed by the workgroup was satisfactory, and also to solicit feedback on ideas for program refinement.

Results

The leadership and workgroup meetings occurred as planned and led to the development of a functional program. The focus groups did not occur as planned, mainly due to the complexity of obtaining research approval for focus groups. The fall prevention program uses an existing telephonic nurse advice line to 1) place outgoing calls to patients at high fall risk, 2) assess these patients' risk factors for falls, and 3) triage these patients to the appropriate services. The workgroup continues to meet monthly to monitor the progress of the program and improve it.

Conclusion

A theory-driven program development process has resulted in the successful initial implementation of a fall prevention program.

Community-based intervention to optimise falls risk management: a randomised controlled trial

BACKGROUND

falls are the leading causes of accidental death and fragility fractures in older adults. Interventions that assess and reduce falls risk are underutilised.

OBJECTIVE

to evaluate the impact of a multifaceted community-based programme aimed at optimising evidence-based management of patients at risk for fall-related fractures.

DESIGN

this was a randomised trial performed from 2003 to 2006.

SETTING

community-based intervention in Ontario, Canada.

PARTICIPANTS

eligible patients were community-dwelling, aged > or =55 years and identified to be at risk for fall-related fractures. A total of 201 patients were allocated to the intervention group or to usual care.

INTERVENTION

components of the intervention included assessment of falls risk, functional status and home environment, and patient education.

MEASUREMENTS

primary outcome was the implementation of appropriate falls risk assessment at 6 months. Secondary outcomes included falls and fractures at 6 and 12 months.

RESULTS

the mean age of participants was 72 years, and 41% had fallen with injury in the previous year. Compared to usual care, the intervention increased the number of referrals made to physiotherapy [21% (21/101) vs 6.0% (6/100); relative risk (RR) 3.47, 95% confidence interval (CI) 1.46-8.22] and occupational therapy [15% (15/101) vs 0%; RR 30.7, 95% CI 1.86 to >500]. At 12 months, the number of falls in the intervention group was greater than in the usual care group [23% (23/101) vs 11% (11/100); RR 2.07, 95% CI 1.07-4.02].

CONCLUSIONS

compared to usual care, a multi-faceted intervention increased referrals to physiotherapy and occupational therapy but did not reduce risk of falls. Similar falls reduction interventions cannot be recommended based on the results of this study.
