Falls among healthy, community‐dwelling, older women: a prospective study of frequency, circumstances, consequences and prediction accuracy

Objective: Most studies of falls among older people have focused on those with some degree of balance or mobility impairment. This study aimed to establish whether falls and associated injuries were a major problem among healthy, older women, whether there were some common features in the falls, and whether these falls could be accurately predicted.

Effectiveness of targeted falls prevention programme in subacute hospital setting: randomised controlled trial

Abstract Objective To assess the effectiveness of a targeted, multiple intervention falls prevention programme in reducing falls and injuries related to falls in a subacute hospital. Design Randomised controlled trial of a targeted multiple intervention programme implemented in addition to usual care compared with usual care alone. Setting Three subacute wards in a metropolitan hospital specialising in rehabilitation and care of elderly patients. Participants 626 men and women aged 38 to 99 years (average 80 years) were recruited from consecutive admissions to subacute hospital wards. Intervention Falls risk alert card with information brochure, exercise programme, education programme, and hip protectors. Main outcome measures Incidence rate of falls, injuries related to falls, and proportion of participants who experienced one or more falls during their stay in hospital. Results Participants in the intervention group (n = 310) experienced 30% fewer falls than participants in the control group (n = 316). This difference was significant (Peto log rank test P = 0.045) and was most obvious after 45 days of observation. In the intervention group there was a trend for a reduction in the proportion of participants who experienced falls (relative risk 0.78, 95% confidence interval 0.56 to 1.06) and 28% fewer falls resulted in injury (log rank test P = 0.20). Conclusions A targeted multiple intervention falls prevention programme reduces the incidence of falls in the subacute hospital setting.

Patient Education to Prevent Falls Among Older Hospital Inpatients: A Randomized Controlled Trial

BACKGROUND Falls are a common adverse event during hospitalization of older adults, and few interventions have been shown to prevent them. METHODS This study was a 3-group randomized trial to evaluate the efficacy of 2 forms of multimedia patient education compared with usual care for the prevention of in-hospital falls. Older hospital patients (n = 1206) admitted to a mixture of acute (orthopedic, respiratory, and medical) and subacute (geriatric and neurorehabilitation) hospital wards at 2 Australian hospitals were recruited between January 2008 and April 2009. The interventions were a multimedia patient education program based on the health-belief model combined with trained health professional follow-up (complete program), multi-media patient education materials alone (materials only), and usual care (control). Falls data were collected by blinded research assistants by reviewing hospital incident reports, hand searching medical records, and conducting weekly patient interviews. RESULTS Rates of falls per 1000 patient-days did not differ significantly between groups (control, 9.27; materials only, 8.61; and complete program, 7.63). However, there was a significant interaction between the intervention and presence of cognitive impairment. Falls were less frequent among cognitively intact patients in the complete program group (4.01 per 1000 patient-days) than among cognitively intact patients in the materials-only group (8.18 per 1000 patient-days) (adjusted hazard ratio, 0.51; 95% confidence interval, 0.28-0.93]) and control group (8.72 per 1000 patient-days) (adjusted hazard ratio, 0.43; 95% confidence interval, 0.24-0.78). CONCLUSION Multimedia patient education with trained health professional follow-up reduced falls among patients with intact cognitive function admitted to a range of hospital wards.

Falls after Stroke

Falls are common at all stages after stroke, occurring in the acute, rehabilitative, and chronic phases. Consequences of falls include death or serious injury, minor injuries, functional limitations, reduced mobility and activity, and fear of falling. These consequences can have implications for independence and quality of life after stroke. The high frequency of falls may be due to a combination of existing falls risk factors prior to the stroke as well as impairments from the stroke, such as decreased strength and balance, hemineglect, perceptual problems, and visual problems. This paper reviews the magnitude of the problem of falls in people with stroke, highlights risk factors, and summarizes the limited randomized controlled trial evidence on falls prevention in this population. There is a need for further high quality research investigating the effectiveness of interventions to reduce falls and injury in people with stroke from onset through to the chronic stage.

Effectiveness of a multifaceted podiatry intervention to prevent falls in community dwelling older people with disabling foot pain: randomised controlled trial.

Objective To determine the effectiveness of a multifaceted podiatry intervention in preventing falls in community dwelling older people with disabling foot pain. Design Parallel group randomised controlled trial. Setting University health sciences clinic in Melbourne, Australia. Participants 305 community dwelling men and women (mean age 74 (SD 6) years) with disabling foot pain and an increased risk of falling. 153 were allocated to a multifaceted podiatry intervention and 152 to routine podiatry care, with 12 months’ follow-up. Interventions Multifaceted podiatry intervention consisting of foot orthoses, advice on footwear, subsidy for footwear (

A100 voucher; £65; €74), a home based programme of foot and ankle exercises, a falls prevention education booklet, and routine podiatry care for 12 months. The control group received routine podiatry care for 12 months. Main outcome measures Proportion of fallers and multiple fallers, falling rate, and injuries resulting from falls during follow-up. Results Overall, 264 falls occurred during the study. 296 participants returned all 12 calendars: 147 (96%) in the intervention group and 149 (98%) in the control group. Adherence was good, with 52% of the participants completing 75% or more of the requested three exercise sessions weekly, and 55% of those issued orthoses reporting wearing them most of the time. Participants in the intervention group (n=153) experienced 36% fewer falls than participants in the control group (incidence rate ratio 0.64, 95% confidence interval 0.45 to 0.91, P=0.01). The proportion of fallers and multiple fallers did not differ significantly between the groups (relative risk 0.85, 0.66 to 1.08, P=0.19 and 0.63, 0.38 to 1.04, P=0.07). One fracture occurred in the intervention group and seven in the control group (0.14, 0.02 to 1.15, P=0.07). Significant improvements in the intervention group compared with the control group were found for the domains of strength (ankle eversion), range of motion (ankle dorsiflexion and inversion/eversion), and balance (postural sway on the floor when barefoot and maximum balance range wearing shoes). Conclusions A multifaceted podiatry intervention reduced the rate of falls in community dwelling older people with disabling foot pain. The components of the intervention are inexpensive and relatively simple to implement, suggesting that the programme could be incorporated into routine podiatry practice or multidisciplinary falls prevention clinics.

Predisposing factors for occasional and multiple falls in older Australians who live at home

OBJECTIVES The primary aim of this study was to identify whether performing a balance task on a force platform while performing a cognitive task (backwards counting by three) could discriminate between healthy older people and older people at mildly increased risk of falling better than performing the balance task alone. Additional aims were to identify the effect of age on balance performance and to investigate the retest reliability and concurrent validity of the balance measures. DESIGN Cross-sectional-cohort, three-group comparison design. SETTING Gait and balance testing laboratory. PARTICIPANTS Twenty healthy young adults (HY, mean age +/- standard deviation = 26.4 +/- 1 years), 20 healthy older adults (HO, 73.8 +/- 6.0 years), and 20 older adults with mild increase in falls risk (MIFR, 74.8 +/- 3 years). MEASUREMENTS All subjects were tested on the balance task alone and while performing a concurrent cognitive task on the Chattecx Balance System (CBS) under three platform conditions: stable platform (stable), dynamic platform with forward-backward tilting (F-B), and dynamic platform with side-to-side tilting (S-S) and on the step test, timed up-and-go, and gait measures. RESULTS There was a significant difference between HY and HO on the S-S and F-B conditions, both with and without the addition of the cognitive task (P< .05), but not under stable platform conditions. There were also significant differences between the HO and MIFR groups under stable and F-B conditions (P< .05). A three-way analysis of variance identified significant main effects for group, platform condition and task (P< .05), group-by-platform interaction, and platform-by-task interaction. The F-B condition with the cognitive task most effectively discriminated between groups. Post hoc analyses revealed that the F-B condition with cognitive task was associated with the highest accuracy in classifying subjects from the two older groups, with a sensitivity of 0.8 and a specificity of 0.8. Retest reliability for most CBS measures was moderate to high, and correlations between dynamic CBS measures and clinical measures were high. CONCLUSION Measurement of dynamic balance on the CBS (F-B) with a cognitive task is a reliable measure that discriminates well between healthy older people and those with a mild increase in risk of falling.

The reliability and predictive accuracy of the falls risk for older people in the community assessment (FROP-Com) tool

This study, which was part of a larger study on the Health Status of Older People conducted in Melbourne, Australia, aimed to identify factors that discriminate between multiple and occasional falls amongst older people living at home. It used a survey of 1000 Australians aged 65 years and over. Subjects were classified as multiple fallers (two or more falls in the past year), occasional fallers (one fall in the past year), or non-fallers. Twenty-nine percent of older people who lived at home reported falling once or more in the previous 12 months. Nearly 20% of older people fell once in the previous 12 months and just under 10% fell more than once. Occasional fallers were more likely to be women (OR 1.75, 95% CI 1.26 to 2.45), to have reported back pain (OR 1.54, 95% CI 1.10 to 2.16) and were nearly twice as likely to have more than three medical conditions compared to non-fallers (OR 1.88, 95% CI 1.22 to 2.90). Multiple fallers were also more likely to be women (OR 1.61, 95% CI 1.03 to 2.51). More multiple fallers (17%) than occasional fallers (9%) reported being very afraid of falling. Intervention strategies should take into account these differing predisposing factors for multiple and occasional falls.

Measuring falls events in acute hospitals - A comparison of three reporting methods to identify missing data in the hospital reporting system

BACKGROUND the Falls Risk for Older People in the Community assessment (FROP-Com) tool was designed for use in targeted multi-factorial falls prevention programmes. It fills the gap between the short screening tools and the longer assessment tools, e.g. the physiological profile assessment (PPA). The aim of this study was to determine the reliability and predictive accuracy of the FROP-Com. METHODS the intra-rater and inter-rater reliability studies were performed with 20 participants each. The prospective study was performed with 344 community-dwelling older people presenting to an emergency department after a fall and being discharged directly home. Following a home-based assessment, including the FROP-Com, Timed Up and Go (TUG) and functional Reach (FR), participants were monitored for falls for 12 months. RESULTS the intra-class correlation coefficient (ICC) for intra-rater reliability and inter-rater reliability for the FROP-Com was 0.93 (95% CI 0.84-0.97) and 0.81 (95% CI 0.59-0.92) respectively. The AUC for the FROP-Com was 0.68 (95% CI 0.63-0.74). At the cut-off 18/19, sensitivity was 71.3% (95% CI 64.4-78.3) and specificity was 56.1% (95% CI 48.9-63.4). The AUC for the TUG was 0.63 (95% CI 0.57-0.69) and for the FR was 0.60 (95% CI 0.54-0.66). CONCLUSION the FROP-Com demonstrated good reliability and a moderate capacity to predict falls.
