Environmental interventions for preventing falls in older people living in the community.

BACKGROUND: Falls and fall-related injuries are common. A third of community-dwelling people aged over 65 years fall each year. Falls can have serious consequences including restricting activity or institutionalisation. This review updates the previous evidence for environmental interventions in fall prevention. OBJECTIVES: To assess the effects (benefits and harms) of environmental interventions (such as fall-hazard reduction, assistive technology, home modifications, and education) for preventing falls in older people living in the community. SEARCH METHODS: We searched CENTRAL, MEDLINE, Embase, other databases, trial registers, and reference lists of systematic reviews to January 2021. We contacted researchers in the field to identify additional studies. SELECTION CRITERIA: We included randomised controlled trials evaluating the effects of environmental interventions (such as reduction of fall hazards in the home, assistive devices) on falls in community-residing people aged 60 years and over.   DATA COLLECTION AND ANALYSIS: We used standard methodological procedures expected by Cochrane. Our primary outcome was rate of falls. MAIN RESULTS: We included 22 studies from 10 countries involving 8463 community-residing older people. Participants were on average 78 years old, and 65% were women. For fall outcomes, five studies had high risk of bias and most studies had unclear risk of bias for one or more risk of bias domains. For other outcomes (e.g. fractures), most studies were at high risk of detection bias. We downgraded the certainty of the evidence for high risk of bias, imprecision, and/or inconsistency.  Home fall-hazard reduction (14 studies, 5830 participants) These interventions aim to reduce falls by assessing fall hazards and making environmental safety adaptations (e.g. non-slip strips on steps) or behavioural strategies (e.g. avoiding clutter).  Home fall-hazard interventions probably reduce the overall rate of falls by 26% (rate ratio (RaR) 0.74, 95% confidence interval (CI) 0.61 to 0.91; 12 studies, 5293 participants; moderate-certainty evidence); based on a control group risk of 1319 falls per 1000 people a year, this is 343 (95% CI 118 to 514) fewer falls. However, these interventions were more effective in people who are selected for higher risk of falling, with a reduction of 38% (RaR 0.62, 95% CI 0.56 to 0.70; 9 studies, 1513 participants; 702 (95% CI 554 to 812) fewer falls based on a control risk of 1847 falls per 1000 people; high-certainty evidence). We found no evidence of a reduction in rate of falls when people were not selected for fall risk (RaR 1.05, 95% CI 0.96 to 1.16; 6 studies, 3780 participants; high-certainty evidence). Findings were similar for the number of people experiencing one or more falls. These interventions probably reduce the overall risk by 11% (risk ratio (RR) 0.89, 95% CI 0.82 to 0.97; 12 studies, 5253 participants; moderate-certainty evidence); based on a risk of 519 per 1000 people per year, this is 57 (95% CI 15 to 93) fewer fallers. However, for people at higher risk of falling, we found a 26% decrease in risk (RR 0.74, 95% CI 0.65 to 0.85; 9 studies, 1473 participants), but no decrease for unselected populations (RR 0.99, 95% CI 0.92 to 1.07; 6 studies, 3780 participants) (high-certainty evidence). These interventions probably make little or no important difference to health-related quality of life (HRQoL) (standardised mean difference 0.09, 95% CI -0.10 to 0.27; 5 studies, 1848 participants; moderate-certainty evidence). They may make little or no difference to the risk of fall-related fractures (RR 1.00, 95% 0.98 to 1.02; 2 studies, 1668 participants), fall-related hospitalisations (RR 0.96, 95% CI 0.87 to 1.06; 3 studies, 325 participants), or in the rate of falls requiring medical attention (RaR 0.91, 95% CI 0.58 to 1.43; 3 studies, 946 participants) (low-certainty evidence). The evidence for number of fallers requiring medical attention was unclear (2 studies, 216 participants; very low-certainty evidence). Two studies reported no adverse events. Assistive technology Vision improvement interventions may make little or no difference to the rate of falls (RaR 1.12, 95% CI 0.84 to 1.50; 3 studies, 1489 participants) or people experiencing one or more falls (RR 1.09, 95% CI 0.79 to 1.50) (low-certainty evidence). We are unsure of the evidence for fall-related fractures (2 studies, 976 participants) and falls requiring medical attention (1 study, 276 participants) because the certainty of the evidence is very low. There may be little or no difference in HRQoL (mean difference 0.40, 95% CI -1.12 to 1.92) or adverse events (falls while switching glasses; RR 1.00, 95% CI 0.98 to 1.02) (1 study, 597 participants; low-certainty evidence). Results for other assistive technology - footwear and foot devices, and self-care and assistive devices (5 studies, 651 participants) - were not pooled due to the diversity of interventions and contexts.  Education  We are uncertain whether an education intervention to reduce home fall hazards reduces the rate of falls or the number of people experiencing one or more falls (1 study; very low-certainty evidence). These interventions may make little or no difference to the risk of fall-related fractures (RR 1.02, 95% CI 0.96 to 1.08; 1 study, 110 participants; low-certainty evidence).  Home modifications We found no trials of home modifications that measured falls as an outcome for task enablement and functional independence. AUTHORS' CONCLUSIONS: We found high-certainty evidence that home fall-hazard interventions are effective in reducing the rate of falls and the number of fallers when targeted to people at higher risk of falling, such as having had a fall in the past year and recently hospitalised or needing support with daily activities. There was evidence of no effect when interventions were targeted to people not selected for risk of falling. Further research is needed to examine the impact of intervention components, the effect of awareness raising, and participant-interventionist engagement on decision-making and adherence.  Vision improvement interventions may or may not impact the rate of falls. Further research is needed to answer clinical questions such as whether people should be given advice or take additional precautions when changing eye prescriptions, or whether the intervention is more effective when targeting people at higher risk of falls. There was insufficient evidence to determine whether education interventions impact falls.

Implementation of a new model of clinical education for regional occupational therapy student clinical placements.

Expansion of occupational therapy education programs has resulted in increased student numbers and demand on clinicians to host clinical placements while also maintaining the delivery of high-quality, safe clinical services to patients. Much of the research about innovative placement models, including student contributions to service delivery, has been conducted in metropolitan areas. Therefore, there is a need to develop models that are suited to regional settings that face diversity of caseload, more generalised occupational therapy roles and variations in patient flow. The aim of the present study was to describe the initial application of the Calderdale Framework in student education in a regional context and look at lessons learnt. The Calderdale Framework provided a structured, clinically governed process whereby occupational therapists were able to determine which tasks could be allocated to students and provided a framework to support student training and competency development. The Calderdale Framework has been used successfully to implement allied health models involving professional skill sharing and delegation of tasks to allied health assistants, but it has not been used in clinical education. Pilot implementation of the Calderdale Framework showed that the model supports quality and safety of student-provided occupational therapy services and that the teaching method provides a platform for student skill development. These results warrant further investigation and are potentially transferrable to student education in other health professions.

Positioning occupational therapy as a discipline on the research continuum: results of a cross-sectional survey of research experience.

BACKGROUND/AIM: Evidence-based practice and research are beginning and endpoints on a research continuum. Progression along the continuum builds research capacity. Occupational Therapy has a low evidence base, thus, clinicians are not implementing evidence-based practice or publishing research. Barriers to implementing evidence-based practice and engaging in research include a lack of confidence. This research gauged Occupational Therapists' research experience, support needs and barriers, and compared levels of research anxiety between allied health disciplines. METHODS: A cross-sectional survey was sent to Health Practitioners in northern Queensland in May-June 2011. Responses about experience, support needs and barriers, between Occupational Therapists, were analysed using Chi-square 'goodness of fit' tests. Multivariate analysis compared responses between disciplines about research anxiety. This paper reports results for the subset of Occupational Therapists. RESULTS: The whole population, consisting of 152 Occupational Therapists, was sent a questionnaire, from which 86 responded. More Occupational Therapists than not had experience of evidence-based practice and less support was required, but they had little experience of producing research and required more support. The amount of support required for activities along the research continuum was inversely related to the level of experience in these tasks. Barriers included lack of staff and time. Occupational Therapists were more anxious about research (53 of 79, 67%) than all other Health Practitioner disciplines combined (170 of 438, 39%, P < 0.0001). CONCLUSION: A cohesive strategy should focus on consolidating Occupational Therapists' evidence-based practice skills and building confidence. Clinicians wishing to engage in research need access to academic support. Academics and clinicians should work closely to produce clinically relevant research.

Assessing the implementation process and outcomes of newly introduced assistant roles: a qualitative study to examine the utility of the Calderdale Framework as an appraisal tool.

Internationally, the health workforce has undergone rapid transformation to help meet growing staffing demands and population requirements. Several tools have been developed to support workforce change processes. The Calderdale Framework (CF) is one such tool designed to facilitate competency-based training by engaging team members in a seven step process involving awareness raising, service and task analysis, competency identification, establishing support systems, training, and sustaining. This paper explores the utility of the CF as an appraisal tool to assess whether adherence to the tool influences outcomes. The CF was applied retrospectively to three complete evaluations of allied health assistant role introduction: a new podiatry assistant role (Australia), speech pathology assistant (Australia), and occupational therapy assistant practitioner role (UK). Adherence to the CF was associated with more effective and efficient use of the role, role flexibility and career development opportunities for assistants, and role sustainability. Services are less likely to succeed in their workforce change process if they fail to plan for and use a structured approach to change, assign targeted leadership, undertake staff engagement and consultation, and perform an initial service analysis. The CF provides a clear template for appraising the implementation of new roles and highlights the potential consequences of not adhering to particular steps in the implementation process.

Environmental assessment and modification to prevent falls in older people.

UNLABELLED: To assess the effectiveness of an environmental falls prevention intervention delivered by qualified occupational therapists or unqualified trained assessors. DESIGN: A pilot three-armed randomized controlled trial. SETTING: Airedale National Health Service Trust catchment, North and West Yorkshire, England. PARTICIPANTS: Two hundred thirty-eight community-dwelling adults aged 70 and older with a history of falls in the previous year. INTERVENTION: Assessment and modification of the home environment of people at greater risk of falls. MEASUREMENTS: Fear of falling was the primary outcome measure, and an analysis of covariance was conducted on the area under the curve at 12 months. As a secondary outcome, falls were analysed using negative binomial regression. Quality of life and independence in activities of daily living (ADLs) were also measured. RESULTS: The intervention had no effect on fear of falling (P=.63). The occupational therapy group had significantly fewer falls than controls 12 months after the assessment (incidence rate ratio (IRR)=0.54, 95% confidence interval (CI)=0.36-0.83, P=.005). There was no significant effect on falls in the trained assessor group (IRR=0.78, 95% CI=0.51-1.21, P=.34). CONCLUSION: Environmental assessment had no effect on fear of falling. Environmental assessment prescribed by an occupational therapist significantly reduced the number of falls in high-risk individuals whereas that prescribed by a trained assessor did not. Further research in other settings is needed to confirm this, to explore the mechanisms, and to estimate cost-effectiveness.
