Process factors explaining the ineffectiveness of a multidisciplinary fall prevention programme: a process evaluation

Barriers and facilitating factors influencing implementation of occupational therapy home assessment recommendations: A mixed methods systematic review

INTRODUCTION

Low implementation rates of occupational therapy home assessment recommendations have previously been reported. The objective was to identify and describe the barriers and facilitating factors that influence implementation of home assessment recommendations.

METHODS

A mixed methods systematic review consisting of studies involving adults living in the community who received an occupational therapy home assessment was conducted. Seven databases were last searched in August 2021. Study quality was assessed using the Joanna Briggs Institute (JBI) critical appraisal tools (SUMARI) dependent on study design. Data synthesis followed the convergent integrated approach. Findings were mapped to the theoretical Capability Opportunity Motivation Behaviour (COM-B) model of health behaviour change.

RESULTS

From 5,540 citations, 22 articles met the criteria for the systematic review. Implementation of occupational therapy home assessment recommendations ranged between 55% and 90%. Six synthesised findings were identified. Capability barriers included a patient's cognitive and physical ability. Motivation barriers included a perceived lack of need and stigma; patient reported decreased involvement and lack of choice. Opportunity barriers included limited family or carer involvement, carer stress, level of service provision available, including funding, therapy dosage and timing and environmental restrictions. Overall facilitators included patient-centred care, including choice and understanding need, individualised tailored recommendations, involvement of families and carers, provision of written record and strategies to support implementation. Results were limited by methodological weaknesses in identified studies and heterogeneity in the definition and measurement of implementation impacting on comparison. Specific intervention components were often poorly described.

CONCLUSION

The theoretical model elucidates priority factors to address for promoting implementation of home assessment recommendations. Future high-quality research clearly defining intervention components is required to support short- and long-term implementation of recommendations in the home environment. Behaviour change techniques could be utilised to support home assessment practices in future research.

Methods and Effectiveness of Communication Between Hospital Allied Health and Primary Care Practitioners: A Systematic Narrative Review

Background

There is a compelling rationale that effective communication between hospital allied health and primary care practitioners may improve the quality and continuity of patient care. It is not known which methods of communication to use, nor how effectively they facilitate the transition of care when a patient is discharged home from hospital. Our systematic review aims to investigate the methods and effectiveness of communication between hospital allied health and primary care practitioners.

Methods

Systematic review of quantitative and qualitative studies with narrative synthesis. Medline, CINAHL, EMBASE, PsycInfo and Proquest Nursing and Allied Health Sources were searched from January 2003 until January 2020 for studies that examined hospital-based allied health professionals communicating with community-based primary care practitioners. Risk of bias in the different study designs was appraised using recognized tools and a content analysis conducted of the methodologies used.

Results

From the located 12,281 papers (duplicates removed), 24 studies met the inclusion criteria with hospital allied health communicating in some form with primary care practitioners. While none of the included studies specifically investigated the methods or effectiveness of communication between hospital allied health and primary care practitioners, 12 of the 24 studies described processes that addressed components of their discharge communication. Four enablers to effective communication between hospital allied health and primary care practitioners were identified: multidisciplinary care plans, patient and caregiver involvement, health information technology and a designated person for follow up/care management.

Conclusion

There is currently no “gold standard” method or measure of communication between hospital allied health and primary care practitioners. There is an urgent need to develop and evaluate multidisciplinary communication with enhanced information technologies to improve collaboration across care settings and facilitate the continuity of integrated people-centered care.

Occupational Therapy and the Use of Technology on Older Adult Fall Prevention: A Scoping Review

Introduction: Falls are the second leading cause of accidental or non-intentional deaths worldwide and are the most common problem as people age. The primary purpose of addressing falls is to detect, prevent, treat, and reduce their incidence and consequences. Previous studies identified that multifactorial programs, an interprofessional team, and assistive technology are required to address falls in older adults effectively. Accordingly, the research question is as follows: what are the scope, type of studies, and approaches and strategies to fall risk using technology in the existing occupational therapy literature regarding interventions to address the effects of falls in older adults on daily living? Methods: This scoping review was carried out in January 2020 through Biblioteca Virtual de Salud España, C.I.N.A.H.L., Cochrane Plus, OTSeeker, PubMed, Scopus, and Web of Science. Results: Twelve papers were included. We analyzed the year and journal of publication, authors' affiliation, and design of the study, and thematic categories. There were three themes: participants' characteristics, type of intervention, and fall approach and type of technology used. Discussion and Conclusions: The literature obtained is scarce. It is considered to still be an emerging theme, especially when considering the use of technology for occupational therapy.

A mixed methods process evaluation of a person-centred falls prevention program

Background

RESPOND is a telephone-based falls prevention program for older people who present to a hospital emergency department (ED) with a fall. A randomised controlled trial (RCT) found RESPOND to be effective at reducing the rate of falls and fractures, compared with usual care, but not fall injuries or hospitalisations. This process evaluation aimed to determine whether RESPOND was implemented as planned, and identify implementation barriers and facilitators.

Methods

A mixed-methods evaluation was conducted alongside the RCT. Evaluation participants were the RESPOND intervention group (n = 263) and the clinicians delivering RESPOND (n = 7). Evaluation data were collected from participant recruitment and intervention records, hospital administrative records, audio-recordings of intervention sessions, and participant questionnaires. The Rochester Participatory Decision-Making Scale (RPAD) was used to evaluate person-centredness (score range 0 (worst) - 9 (best)). Process factors were compared with pre-specified criteria to determine implementation fidelity. Six focus groups were held with participants (n = 41), and interviews were conducted with RESPOND clinicians (n = 6). Quantitative data were analysed descriptively and qualitative data thematically. Barriers and facilitators to implementation were mapped to the ‘Capability, Opportunity, Motivation – Behaviour’ (COM-B) behaviour change framework.

Results

RESPOND was implemented at a lower dose than the planned 10 h over 6 months, with a median (IQR) of 2.9 h (2.1, 4). The majority (76%) of participants received their first intervention session within 1 month of hospital discharge with a median (IQR) of 18 (12, 30) days. Clinicians delivered the program in a person-centred manner with a median (IQR) RPAD score of 7 (6.5, 7.5) and 87% of questionnaire respondents were satisfied with the program. The reports from participants and clinicians suggested that implementation was facilitated by the use of positive and personally relevant health messages. Complex health and social issues were the main barriers to implementation.

Conclusions

RESPOND was person-centred and reduced falls and fractures at a substantially lower dose, using fewer resources, than anticipated. However, the low dose delivered may account for the lack of effect on falls injuries and hospitalisations. The results from this evaluation provide detailed information to guide future implementation of RESPOND or similar programs.

Trial registration

This study was registered with the Australian New Zealand Clinical Trials Registry, number ACTRN12614000336684 (27 March 2014).

Effects of the falls and fractures clinic as an integrated multidisciplinary model of care in Australia: a pre-post study

OBJECTIVES

Traditionally, the approach to fracture prevention has focused on increasing bone mineral density while typically lacking a combined clinical approach to falls prevention and vice versa. To resolve this gap, we implemented and evaluated a novel combined model of care to the assessment and prevention of osteoporosis and falls in the outpatients setting.

SETTING

Falls and Fractures Clinic (FFC) at Nepean Hospital (Penrith, NSW, Australia).

PARTICIPANTS

Pre-effects and posteffects assessment of 106 community-dwelling older patients referred from the community.

PRIMARY AND SECONDARY OUTCOME MEASURES

Previous falls and fractures were recorded. Clinical, functional and paraclinical evaluations were performed. A comprehensive multidisciplinary care plan was then tailored based on the presence of risk factors. Six-month follow-ups were performed assessing the incidence of falls and fractures, change in risk factors for falls and level of risk, with the recommended plan.

RESULTS

We report that 97% of patients had a fall in the preceding 6 months, 47.6% of whom experienced a fracture from the fall. Furthermore, 64% of patients had a marked risk for falling by Physiological Profile Assessment (PPA), 90% had intermediate-high 10-year probability of fracture according to FRAX and 78% had sarcopenia. At 6-month follow-up, we observed more than an 80% reduction in falls and recurrent falls, and 50% reduction in fractures. In addition, 65% of patients had reduced PPA and a 57% reduction in 10-year fracture probability.

CONCLUSIONS

In conclusion, we suggest that a multidisciplinary FFC can provide substantial reductions in falls and fractures for high-risk older people, even over a relatively short 6-month time period. The current model of service provision via traditional falls clinics could be significantly improved by encompassing fracture prevention within the multifactorial approach to interventions.

Multifactorial and multiple component interventions for preventing falls in older people living in the community

BACKGROUND

Falls and fall-related injuries are common, particularly in those aged over 65, with around one-third of older people living in the community falling at least once a year. Falls prevention interventions may comprise single component interventions (e.g. exercise), or involve combinations of two or more different types of intervention (e.g. exercise and medication review). Their delivery can broadly be divided into two main groups: 1) multifactorial interventions where component interventions differ based on individual assessment of risk; or 2) multiple component interventions where the same component interventions are provided to all people.

OBJECTIVES

To assess the effects (benefits and harms) of multifactorial interventions and multiple component interventions for preventing falls in older people living in the community.

SEARCH METHODS

We searched the Cochrane Bone, Joint and Muscle Trauma Group Specialised Register, the Cochrane Central Register of Controlled Trials, MEDLINE, Embase, the Cumulative Index to Nursing and Allied Health Literature, trial registers and reference lists. Date of search: 12 June 2017.

SELECTION CRITERIA

Randomised controlled trials, individual or cluster, that evaluated the effects of multifactorial and multiple component interventions on falls in older people living in the community, compared with control (i.e. usual care (no change in usual activities) or attention control (social visits)) or exercise as a single intervention.

DATA COLLECTION AND ANALYSIS

Two review authors independently selected studies, assessed risks of bias and extracted data. We calculated the rate ratio (RaR) with 95% confidence intervals (CIs) for rate of falls. For dichotomous outcomes we used risk ratios (RRs) and 95% CIs. For continuous outcomes, we used the standardised mean difference (SMD) with 95% CIs. We pooled data using the random-effects model. We used the GRADE approach to assess the quality of the evidence.

MAIN RESULTS

We included 62 trials involving 19,935 older people living in the community. The median trial size was 248 participants. Most trials included more women than men. The mean ages in trials ranged from 62 to 85 years (median 77 years). Most trials (43 trials) reported follow-up of 12 months or over. We assessed most trials at unclear or high risk of bias in one or more domains.Forty-four trials assessed multifactorial interventions and 18 assessed multiple component interventions. (I² not reported if = 0%).Multifactorial interventions versus usual care or attention controlThis comparison was made in 43 trials. Commonly-applied or recommended interventions after assessment of each participant's risk profile were exercise, environment or assistive technologies, medication review and psychological interventions. Multifactorial interventions may reduce the rate of falls compared with control: rate ratio (RaR) 0.77, 95% CI 0.67 to 0.87; 19 trials; 5853 participants; I² = 88%; low-quality evidence. Thus if 1000 people were followed over one year, the number of falls may be 1784 (95% CI 1553 to 2016) after multifactorial intervention versus 2317 after usual care or attention control. There was low-quality evidence of little or no difference in the risks of: falling (i.e. people sustaining one or more fall) (RR 0.96, 95% CI 0.90 to 1.03; 29 trials; 9637 participants; I² = 60%); recurrent falls (RR 0.87, 95% CI 0.74 to 1.03; 12 trials; 3368 participants; I² = 53%); fall-related hospital admission (RR 1.00, 95% CI 0.92 to 1.07; 15 trials; 5227 participants); requiring medical attention (RR 0.91, 95% CI 0.75 to 1.10; 8 trials; 3078 participants). There is low-quality evidence that multifactorial interventions may reduce the risk of fall-related fractures (RR 0.73, 95% CI 0.53 to 1.01; 9 trials; 2850 participants) and may slightly improve health-related quality of life but not noticeably (SMD 0.19, 95% CI 0.03 to 0.35; 9 trials; 2373 participants; I² = 70%). Of three trials reporting on adverse events, one found none, and two reported 12 participants with self-limiting musculoskeletal symptoms in total.Multifactorial interventions versus exerciseVery low-quality evidence from one small trial of 51 recently-discharged orthopaedic patients means that we are uncertain of the effects on rate of falls or risk of falling of multifactorial interventions versus exercise alone. Other fall-related outcomes were not assessed.Multiple component interventions versus usual care or attention controlThe 17 trials that make this comparison usually included exercise and another component, commonly education or home-hazard assessment. There is moderate-quality evidence that multiple interventions probably reduce the rate of falls (RaR 0.74, 95% CI 0.60 to 0.91; 6 trials; 1085 participants; I² = 45%) and risk of falls (RR 0.82, 95% CI 0.74 to 0.90; 11 trials; 1980 participants). There is low-quality evidence that multiple interventions may reduce the risk of recurrent falls, although a small increase cannot be ruled out (RR 0.81, 95% CI 0.63 to 1.05; 4 trials; 662 participants). Very low-quality evidence means that we are uncertain of the effects of multiple component interventions on the risk of fall-related fractures (2 trials) or fall-related hospital admission (1 trial). There is low-quality evidence that multiple interventions may have little or no effect on the risk of requiring medical attention (RR 0.95, 95% CI 0.67 to 1.35; 1 trial; 291 participants); conversely they may slightly improve health-related quality of life (SMD 0.77, 95% CI 0.16 to 1.39; 4 trials; 391 participants; I² = 88%). Of seven trials reporting on adverse events, five found none, and six minor adverse events were reported in two.Multiple component interventions versus exerciseThis comparison was tested in five trials. There is low-quality evidence of little or no difference between the two interventions in rate of falls (1 trial) and risk of falling (RR 0.93, 95% CI 0.78 to 1.10; 3 trials; 863 participants) and very low-quality evidence, meaning we are uncertain of the effects on hospital admission (1 trial). One trial reported two cases of minor joint pain. Other falls outcomes were not reported.

AUTHORS' CONCLUSIONS

Multifactorial interventions may reduce the rate of falls compared with usual care or attention control. However, there may be little or no effect on other fall-related outcomes. Multiple component interventions, usually including exercise, may reduce the rate of falls and risk of falling compared with usual care or attention control.

Out of sight, out of mind? Does terminating the physical presence of a geriatric consultant in the community clinic reduce the implementation rate for geriatric recommendations

AIM

To assess the effect of moving the geriatric consultation from the primary care clinic to another setting, on the rate of implementation of geriatric recommendations by family physicians.

METHODS

A retrospective review of the computerized medical records of elderly patients in four primary care clinics. The rate of implementation of geriatric recommendations was compared between clinics in which a geriatric consultant was physically present (control clinics) and a clinic where the consultation took place elsewhere (study clinic). In addition, the results of the present study were compared to a previous study in which the geriatric consultation was carried out in the study clinic and the family doctor was an active participant.

RESULTS

127 computerized files were reviewed in the study clinic and 133 in the control clinics. The mean age of the patients was 81.1±6.3 years and 63.1% were women. The overall implementation of geriatric recommendations by family doctors in the study clinic was 55.9%, a statistically significant decrease compared to the previous study where the rate was 73.9% (p<0.0001). In contrast, there was no change in the implementation rate in the control clinics at 65.0% in the present study and 59.9% in the previous one (p=0.205).

CONCLUSIONS

Direct, person-to-person contact between the geriatric consultant and the family doctor has a beneficial effect on the implementation of geriatric recommendations. This should be considered by healthcare policy makers when planning geriatric services in the community.

Occupational therapy for elderly. Evidence mapping of randomised controlled trials from 2004-2012

OBJECTIVE

Previous systematic reviews on occupational therapy for elderly included studies until 2003. The present evidence mapping summarizes recent evidence for the efficacy of occupational therapy with older persons based on randomised controlled trials from 2004-2012.

METHOD

An electronic search in Cochrane and Medline databases identified publications of randomised controlled trials on occupational therapy interventions for persons≥65 years old. Two raters independently extracted data and analysed the quality of samples, interventions and outcome evalutations according to PRISMA criteria.

RESULTS

In all, 136 abstracts were identified and 48 studies analysed, from these 12 on stroke, 15 on falls and mobility, 7 on dementia, 4 on prevention and 10 on other conditions. Reports of adverse events and evaluations of costs and long-term outcomes are frequently lacking.

CONCLUSION

The most promising fields for further research are primary and secondary prevention in persons with stroke, falls or mobility problems and tertiary prevention in persons with dementia. Future trials should be conducted and reported according to consented reporting guidelines of the equator network.

RESPOND: a patient-centred programme to prevent secondary falls in older people presenting to the emergency department with a fall-protocol for a mixed methods programme evaluation

BACKGROUND

Programme evaluations conducted alongside randomised controlled trials (RCTs) have potential to enhance understanding of trial outcomes. This paper describes a multi-level programme evaluation to be conducted alongside an RCT of a falls prevention programme (RESPOND).

OBJECTIVES

(1) To conduct a process evaluation in order to identify the degree of implementation fidelity and associated barriers and facilitators. (2) To evaluate the primary intended impact of the programme: participation in fall prevention strategies and the factors influencing participation. (3) To identify the factors influencing RESPOND RCT outcomes: falls, fall injuries and emergency department (ED) re-presentations.

METHODS/DESIGN

528 community-dwelling adults aged 60-90 years presenting to two EDs with a fall will be recruited and randomly assigned to the intervention or standard care group. All RESPOND participants and RESPOND clinicians will be included in the evaluation. A mixed methods design will be used and a programme logic model will frame the evaluation. Data will be sourced from interviews, focus groups, questionnaires, clinician case notes, recruitment records, participant-completed calendars, hospital administrative datasets and audio-recordings of intervention contacts. Quantitative data will be analysed via descriptive and inferential statistics and qualitative data will be interpreted using thematic analysis.

DISCUSSION

The RESPOND programme evaluation will provide information about contextual and influencing factors related to the RESPOND RCT outcomes. The results will assist researchers, clinicians and policy makers regarding decisions about future falls prevention interventions. Insights gained may be applicable to a range of chronic conditions where similar preventive intervention approaches are indicated.

TRIAL REGISTRATION NUMBER

This programme evaluation is linked to the RESPOND RCT which is registered with the Australian New Zealand Clinical Trials Registry (ACTRN12614000336684).

Data sharing between home care professionals: a feasibility study using the RAI Home Care instrument

BACKGROUND

Across Ontario, home care professionals collect standardized information on each client using the Resident Assessment for Home Care (RAI-HC). However, this information is not consistently shared with those professionals who provide services in the client's home. In this pilot study, we examined the feasibility of sharing data, from the RAI-HC, between care coordinators and service providers.

METHODS

All participants were involved in a one-day training session on the RAI-HC. The care coordinators shared specific outputs from the RAI-HC, including the embedded health index scales, with their contracted physiotherapy and occupational therapy service providers. Two focus groups were held, one with care coordinators (n = 4) and one with contracted service providers (n = 6). They were asked for their opinions on the positive aspects of the project and areas for improvement.

RESULTS

The focus groups revealed a number of positive outcomes related to the project including the use of a falls prevention brochure and an increased level of communication between professionals. The participants also cited multiple areas for improvement related to data sharing (e.g., time constraints, data being sent in a timely fashion) and to their standard practices in the community (e.g., busy workloads, difficulties in data sharing, duplication of assessments between professionals).

CONCLUSIONS

Home care professionals were able to share select pieces of information generated from the RAI-HC system and this project enhanced the level of communication between the two groups of professionals. However, a single information session was not adequate training for the rehabilitation professionals, who do not use the RAI-HC as part of normal practice. Better education, ongoing support and timely access to the RAI-HC data are some ways to improve the usefulness of this information for busy home care providers.

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.

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 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.

How to perform a preplanned process evaluation for complex interventions in geriatric medicine: exemplified with the process evaluation of a complex falls-prevention program for community-dwelling frail older fallers

Complex interventions are difficult to develop, document, evaluate, and reproduce. Process evaluations aid the interpretation of outcome results by documenting and evaluating each process step in detail. Despite its importance, process evaluations are not embedded in all evaluations of complex interventions. Based on literature, we structured the process evaluation for trials on complex interventions into 3 main components: (1) the success rate of recruitment and quality of the study population, (2) the quality of execution of the complex intervention, and (3) the process of acquisition of the evaluation data. To clarify these process evaluation components and measures, we exemplified them with the preplanned process evaluation of a complex falls-prevention program for community-dwelling frail older fallers and their informal caregivers. The 3 process evaluation components are operationalized, results are presented, and implications discussed. This process evaluation identified several limitations of the intervention and effect study, and resulted in multiple recommendations for improvement of both the intervention as well as the trial. Thus, a good-quality process evaluation gives a detailed description of the most important components of a complex intervention, resulting in an in-depth insight in the actually performed intervention and effect analysis. This allows us to draw the appropriate conclusions on positive or negative trial results, and results in recommendations for implementation, or adjustment of the intervention or effect evaluation, respectively.

Determinants of participation in a fall assessment and prevention programme among elderly fallers in Hong Kong: prospective cohort study

AIMS

The study was undertaken to estimate the uptake rate of a fall prevention programme among older fallers and explore related factors.

BACKGROUND

Fall injuries are a major cause nationally of the loss of independence in old age, but they are preventable. Acceptance of fall prevention programmes is therefore important to reduce the risk of falling.

METHODS

Patients aged ≥60 attending the Department of Accident & Emergency of a regional hospital in Hong Kong between 2006 and 2007 were recruited. The study included a baseline interview, focus group interview and a cross-sectional 1-year follow-up telephone survey to assess uptake and its related factors.

RESULTS

A total 68% of 1194 older people attended the fall programme. Factors associated with programme participation included the perception of fall as being preventable [OR=3.47, 95% CI (1.59-7.56)] or recoverable [OR=1.73, 95% CI (1.06-2.82)], a safe outside environment; absence of chronic illness, and ability to walk without aids. Old-age people, those living in old-age homes and of lower education level were less likely to join the programme.

CONCLUSION

Older people with the selected characteristics were less likely to attend the fall prevention programme, thus were less likely to benefit from them. Support from family/carers may be an important element in participation. In a nursing context, in primary care practice, all of these factors should be taken into account in any future development of a fall prevention programme in Hong Kong of this nature.

Falls in aged people of the Chinese mainland: epidemiology, risk factors and clinical strategies

Falls are a common and serious problem for aged people, causing an enormous amount of morbidity, mortality and burden to both the immediate family and the society in terms of healthcare utilization and costs. In the Chinese mainland, epidemiological data indicates a predilection for single falls, with women more at risk than men. A variety of risk factors such as weakness, unsteady gait, mental confusion and use of certain medications are associated with falls in the elderly. Addressing these risk factors can be expected to reduce rates of falling. Targeted fall risk assessments are the most effective preventive procedures, and include a plethora of assessment instruments that have been developed and designed for different purposes over the decades. Strategies for control of elderly falls have been established differently, taking into account the complex physiological and pathological conditions of the elderly. The optimal approach involves interdisciplinary assessments, physical exercise, medical intervention, environmental inspection and hazard abatement. In China, the 25 million falls suffered annually by the estimated 20 million elderly population exacts direct medical costs of about 5 billion yuan and social costs of 60-80 billion yuan. Fall-prevention strategies will thus have profound social and economic benefits.

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.

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.

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.
