Predictors of fall protection motivation among older adults in rural communities in a middle-income country: A cross-sectional study using the Protection Motivation Theory

AIMS

To evaluate factors associated with fall protection motivation to engage in fall preventive behaviour among rural community-dwelling older adults aged 55 and above using the protection motivation theory scale.

DESIGN

A cross-sectional study.

METHODS

The study was conducted in a healthcare clinic in Malaysia, using multistage random sampling from November 2021 to January 2022. Three hundred seventy-five older adults aged 55 and older were included in the final analysis. There were 31 items in the final PMT scale. The analysis was performed within the whole population and grouped into 'faller' and 'non-faller', employing IBM SPSS version 26.0 for descriptive, independent t-test, chi-square, bivariate correlation and linear regressions.

RESULTS

A total of 375 older participants were included in the study. Fallers (n = 82) and non-fallers (n = 293) show statistically significant differences in the characteristics of ethnicity, assistive device users, self-rating of intention and participation in previous fall prevention programmes. The multiple linear regression model revealed fear, coping appraisal and an interaction effect of fear with coping appraisal predicting fall protection motivation among older adults in rural communities.

CONCLUSION

Findings from this study demonstrated that coping appraisal and fear predict the protection motivation of older adults in rural communities. Older adults without a history of falls and attaining higher education had better responses in coping appraisal, contributing to a reduction in perceived rewards and improving protection motivation. Conversely, older adults from lower education backgrounds tend to have higher non-preventive behaviours, leading to a decline in fall protection motivation.

IMPLICATIONS FOR THE PROFESSION AND/OR PATIENT CARE

These results contribute important information to nurses working with older adults with inadequate health literacy in rural communities, especially when planning and designing fall prevention interventions. The findings would benefit all nurses, healthcare providers, researchers and academicians who provide care for older adults.

PATIENT OR PUBLIC CONTRIBUTION

Participants were briefed about the study, and their consent was obtained. They were only required to answer the questionnaire through interviews. Older individuals aged fifty-five and above in rural communities at the healthcare clinic who could read, write or understand Malay or English were included. Those who were suffering from mental health problems and refused to participate in the study were excluded from the study. Their personal information remained classified and not recorded in the database during the data entry or analysis.

Exploring the Potential of a Behavior Theory-Informed Digital Intervention for Infant Fall Prevention: Mixed Methods Longitudinal Study

BACKGROUND

Falls are the most common hospitalized injury mechanism in children aged ≤1 years, and currently, there are no targeted prevention interventions. The prevention of falls in children of this age requires changes in the behavior of their caregivers, and theoretically informed digital behavior change interventions (DBCIs) may provide a unique mechanism for achieving effective intervention. However, user acceptance and the ability of DBCIs to effect the required changes in behavior are critical to their likelihood of success.

OBJECTIVE

This study aims to evaluate a behavior theory-informed digital intervention developed following a user-centered approach for user experience, the potential for this intervention to prevent infant falls, and its impact on behavioral drivers underpinning fall risk in young children.

METHODS

Parents of infants aged <1 year were recruited and asked to use the intervention for 3 months. A pre-post longitudinal design was used to examine the change in the potential to reduce the risk of falls after a 3-month exposure to the intervention. Postintervention data on behavioral drivers for fall prevention, user acceptability, and engagement with the app were also collected. Interviews were conducted to explore user experiences and identify areas for further improvement of the intervention.

RESULTS

A total of 62 parents participated in the study. A statistically significant effect on the potential to reduce falls was observed after the intervention. This effect was higher for new parents. Parents agreed that the intervention targeted most of the target behavior drivers. The impact of behavior drivers and intervention on the potential for fall prevention had a positive correlation. The intervention demonstrated good levels of acceptability. Feedback from participants was mostly positive, and the primary area identified for further improvement was widening the scope of the intervention.

CONCLUSIONS

This study demonstrated the promise of a newly developed digital intervention to reduce the risk of infant falls, particularly among new parents. It also showed a positive influence of the DBCI on the drivers of parental behaviors that are important for fall reduction among infants. The acceptability of the app was high, and important insights were gained from users about how to further improve the app.

A Clinical Data Warehouse Analysis of Risk Factors for Inpatient Falls in a Tertiary Hospital: A Case-Control Study

OBJECTIVES

The aims of the study are to identify fall risk factors and to establish automatic risk assessments based on clinical data from electronic medical records of hospitalized patients.

METHODS

In this retrospective case-control study, we reviewed the electronic medical records of 1454 patients (292 and 1162 patients in the fall and nonfall groups, respectively) who were hospitalized at a 1800-bed tertiary hospital in South Korea between January 1, 2017, and December 31, 2017. Patients' age, sex, and clinical department were matched, and all laboratory reports, clinical flow sheets, and nursing initial assessment records of case from the Clinical Data Warehouse system were analyzed. The collated patient records data were analyzed using SAS (version 9.4) and logistic regression.

RESULTS

Overall, 65 risk factors, including low body mass index, low blood pressure, low albumin levels, high fasting blood sugar level, low red blood cell counts, and high potassium levels, that significantly increased the incidence of falls were identified. Falls were also associated with 21 items from the clinical flow sheet and nursing initial assessment, including frequent bowel movements, 24-hour urine tests, imaging tests, biopsy, pain, intravenous tubes, unclear consciousness, and taking medication.

CONCLUSIONS

Fall risk factors identified via the Clinical Data Warehouse can be used to build an automated detection system to detect fall risk in electronic medical records, enabling nurses to assess the fall risk in addition to using the fall scale.

Outcomes of Elevated Blood Alcohol Concentrations in Elderly Patients Following a Ground Level Fall: A Matched Analysis from the National Trauma Quality Program

BACKGROUND

The rising elderly population and the concomitant increase in alcohol consumption can result in a ground level fall (GLF). The purpose of this study is to evaluate the in-hospital mortality, hospital length of stay, and discharge disposition of elderly patients who sustained a ground level fall (GLF) and tested positive for an elevated blood alcohol concentration (BAC).

METHODS

The data of patients who were 65 years and older, had an injury after a GLF, and tested for BAC were accessed from the American College of Surgeon -Trauma Quality improvement Program (ACS-TQIP) from the calendar year of 2011-2016. Patients' demography, injury, comorbidities, and outcomes were compared between the groups who tested positive (>0.08g/dl) and negative (0 mg/dl) for BAC. Univariate, followed by matched analyses were performed. All p values are two sided, and a p value <0.05 is considered statistically significant.

RESULTS

Out of 20,163 patients who satisfied the inclusion criteria, 2,398 (∼12%) patients tested positive for an elevated BAC. There were significant differences found between the two groups, BAC positive vs. BAC negative, in univariate analysis for age and sex with P values <0.001. Propensity score matching balanced demographic characteristics; however, differences remained in certain comorbidities. Exact matching balanced patient demography, injury, and comorbidities. The paired matched analysis showed no significant differences between the two groups for in-hospital mortality (2.1% vs. 2.1%, P=1) and median hospital length of stay (5[4-5] vs. 5[5-5], P=0.307). A higher proportion of patients in BAC group suffered from alcohol withdrawal syndrome (AWS) and deep vein thrombosis (DVT) complications (9.5% vs. 1.4%, P<0.001 and 1.5% vs. 0.5%, P=0.018) compared to BAC negative patients. A slightly higher percentage of patients in the BAC positive group were discharged home without any additional services (39.6% vs. 36.9%, P<0.001).

CONCLUSION

Of the elderly patients who sustained a GLF and tested for BAC, approximately 12% tested positive for BAC. The overall in-hospital mortality was 2.1%. The BAC-positive group suffered from higher complications of AWS and DVT, and more than 60% of patients required additional services at the time of discharge.

A fatal case of paediatric post-traumatic pyomyositis

A 6-year-old girl was brought to the emergency department with a history of an accidental fall a few days earlier. She presented with a fever, cough and constipation. Sars-CoV-2 infection being suspected, she was transferred to a paediatric facility for Covid-positive patients. During the diagnostic process, the clinical picture suddenly deteriorated with the development of bradycardia, tachypnea and altered sensorium. Despite cardiopulmonary resuscitation attempts, the child died about 16 hours after admission to the emergency department. A judicial forensic autopsy was performed that concluded that her death was due to multiple acute pulmonary, cardiac and renal infarctions secondary to septic thromboembolism in the course of post-traumatic bacterial necrotizing pyomyositis of the right ileo-psoas muscle.

The relationship between fall and loneliness among older people in China: the mediating role of personality trait

Aims

We aimed to explore the role of personality traits between fall and loneliness.

Methods

A questionnaire survey was used to investigate falls, the big five personality traits, and loneliness among older people (≥ 60 years old) in China mainland.

Results

A total of 4,289 older people participated in the survey. There are significant differences in age, marital status, education level, residence, solitariness, and fall in relation to loneliness among older people. Falls, especially when they occurred one time increase the loneliness of older people. Agreeableness, conscientiousness, and neuroticism were significant mediating effects between falls and loneliness.

Conclusion

This study implied that agreeableness, conscientiousness, and neuroticism were meditating factors between falls and loneliness. In the future, we should consider the big five personality traits more to understand loneliness and offer older people interventions for reducing their loneliness. The study design was cross-sectional, so the temporal precedence of mediators and causality could not be tested. Because the data were collected retrospectively, current loneliness is likely to have confounding effects on retrospective recall.

Development and Evaluation of Syndromic Surveillance Definitions for Fall- and Hip Fracture-Related Emergency Department Visits Among Adults Aged 65 Years and Older, United States 2017-2018

OBJECTIVE

To develop syndromic surveillance definitions for unintentional fall- and hip fracture-related emergency department (ED) visits among older adults (aged ≥65 years) for use in the Centers for Disease Control and Prevention's National Syndromic Surveillance Program (NSSP) data and compare the percentage of ED visits captured using these new syndromes with ED visits from the Healthcare Cost and Utilization Project Nationwide Emergency Department Sample (HCUP-NEDS), a nationally representative administrative data set.

DESIGN/SETTING

Syndromic definitions were developed using chief complaint terms and discharge diagnosis codes in NSSP data. The percentages of ED visits among older adults related to falls and hip fractures in NSSP were compared with the percentages in HCUP-NEDS in 2017 and 2018.

MEASURES

Prevalence ratios were calculated as the relative difference in the percentage of ED visits related to falls or hip fractures in NSSP compared with HCUP-NEDS. Counts and percentages calculated using HCUP-NEDS were weighted to produce nationally representative estimates. Data were analyzed overall and by sex and age group.

RESULTS

The percentage of ED visits among older adults related to falls in NSSP was 12% less in 2017 (10.81%) and 7% less in 2018 (11.42%) compared with HCUP-NEDS (2017: 12.30%; 2018: 12.26%). The percentage of ED visits among older adults related to hip fractures in NSSP was 41% less in 2017 (0.65%) and 30% less in 2018 (0.76%) compared with HCUP-NEDS (2017: 1.10%; 2018: 1.09%). In both 2017 and 2018, a higher percentage of ED visits among older women and adults aged 85 years or older were related to falls or hip fractures compared with older men and younger age groups across both data sets.

CONCLUSION

A smaller percentage of older adults' ED visits met the falls and hip fracture definitions in NSSP compared with HCUP-NEDS in 2017 and 2018. However, demographic trends remained similar across both data sets.

Effects of Muscle Strength, Agility, and Fear of Falling on Risk of Falling in Older Adults

Falls are a major public health problem among older adults because they lead to premature mortality, loss of autonomy, and increased dependence on others. However, these associations have not been explored using procedures that analyze the sequential effects between risk factors of falling. The present study aimed to examine the effects of muscle strength, agility, and fear of falling on risk of falling using path analysis in community-dwelling older adults. In total, 49 elderly (female = 33, male = 16) participants aged between 65 and 76 years (M = 68.38 years; SD = 6.22) were included for analysis. Muscle strength, agility, fear of falling, and risk of falling were assessed using validated instruments for the older adult population. The proposed model shows that muscle strength was negatively associated with agility. Consequently, agility was negatively associated with fear of falling. The same trend appeared between fear of falling and risk of falling. The effect sizes were between small and medium for agility (R² = 0.16), fear of falling, (R² = 0.29), and risk of falling (R² = 0.03). The main finding of the present study was that muscle strength was significantly correlated with agility, which, in turn, predicted fear of falling. Consequently, lower scores for fear of falling explained lower risk of falling in community-dwelling older adults. While muscle strength is a crucial component of physical fitness, only with adequate levels of agility can older adults possess the efficacy and ability to perform daily tasks.

The association between the use of shift schedule evaluation tool with ergonomics recommendations and occupational injuries: A 4-year prospective cohort study among healthcare workers

OBJECTIVE

This study aimed to find out whether utilizing a shift schedule evaluation tool with ergonomics recommendations for working hours has favorable effects on the incidence of occupational injuries.

METHODS

This 4-year prospective cohort study (2015-2018) consisted of a dynamic cohort of healthcare shift workers (N=29 237) from ten hospital districts and six cities in Finland. Working hour characteristics and occupational injuries were measured with daily registry data. Multilevel generalized linear model was used for the analyses, and the estimates were controlled for hierarchical structure of the data and confounders.

RESULTS

Ward heads of the cities used the shift schedule evaluation tool 3.2 times more often than ward heads of the hospital districts. Overall incidence of workplace and commuting injuries did not differ between users and non-users of the evaluation tool. The incidence of dislocations, sprains, and strains was lower in the users than non-users [adjusted odds ratio (OR) 0.88, 95% confidence interval (CI) 0.78-0.99]. Approximately 13% of this association was mediated by increase in realized shift wishes and 10% by increase in single days off. In subgroup analyses, the incidence of workplace injury (OR 0.83, 95% CI 0.69-0.99), and among types of injuries, the incidence of dislocations, sprains, and strains (OR 0.69, 95% CI 0.55-0.85) and falling, slipping, tripping, or overturning (OR 0.75, 95% CI 0.58-0.99) were lower in users than non-users among employees of the cities, but no association was found among employees of the hospital districts.

CONCLUSION

The use of ergonomics recommendations for working hours is associated with a reduced risk of occupational injuries.

Risk assessment of accidental falls in patients taking trazodone, quetiapine, or risperidone for insomnia: A single-center, case-control study

AIM

No consensus has been reached on the association between the risk of falls and antipsychotic and antidepressant drug use. In this study, we evaluated the risk of falls with trazodone, risperidone, and quetiapine, which are recommended for use at Kanazawa Medical University Hospital.

METHODS

We reviewed all patients who were admitted to Kanazawa Medical University Hospital between January 1st and December 31st, 2018. We excluded those aged <20 years and those admitted to pediatric, intensive care, and psychiatric wards. Finally, 9273 patients were included. We reviewed the incidence in these patients of accidental falls reported to the medical safety department. We noted whether these patients received trazodone, quetiapine, or risperidone. We also observed whether they were taking a benzodiazepine receptor agonist, which is a known risk factor. We further examined each patient's age, sex, the department they were visiting, and their diseases. Patients were considered to have taken medication if it was administered within 24 hours before an accidental fall. Multiple logistic regression analysis was used to evaluate the risk of accidental fall.

RESULTS

Multivariate analysis showed that the adjusted odds ratios (OR) for each medication (with 95% confidence intervals) were: trazodone (OR, 0.47 [0.27-0.80]), quetiapine (OR, 1.06 [0.46-2.46]), and risperidone (OR, 0.82 [0.41-1.63]).

CONCLUSION

The association of risperidone and quetiapine with accidental falls was unclear. Interestingly, however, trazodone may help reduce the risk, which makes it a potential pharmacologic treatment option for insomnia in patients at high risk for accidental falls.

Prevalence, risk factors and effectiveness of falls prevention interventions for adults living with Mild Cognitive Impairment in the community: A systematic review and meta-analysis

OBJECTIVES

To identify falls prevalence, falls risk factors and evaluate the effectiveness of falls prevention interventions for community-dwelling people with Mild Cognitive Impairment.

DATA SOURCES

Peer-reviewed articles (inception to 4 August 2022) from PubMed, CINAHL, PsycInfo, EMBASE, Scopus, SportDiscus and the Cochrane library.

REVIEW METHODS

All types of methodological approaches were considered. Inclusion criteria were community-dwelling; diagnosis of Mild Cognitive Impairment; aged 50+ years. Interventions needed to include falls prevention programs aiming to reduce falls and/or risk of falls. Outcomes of interest included number and/or rate of falls, falls prevalence and falls risk factors. For controlled trials, any control group was included. Quality assessment was completed using Cochrane's Risk of Bias Tool for randomized controlled trials and the Standard Quality Assessment Criteria for Evaluating Primary Research Papers from a Variety of Fields for all other studies. Where statistical data pooling was not possible, narrative synthesis was used to present data in tables and figures.

RESULTS

Forty-seven studies were included. Prevalence of falls was 43% when data were gathered prospectively for 12 months. Confirmed falls risk factors included slow gait, dual-tasking, postural control and non-amnesic Mild Cognitive Impairment. Few studies evaluated interventions to reduce falls. Six meta-analyses were conducted, no significant reduction in falls was found.

CONCLUSIONS

Until further high-quality, adequately powered studies are available to guide practice, best practice guidelines recommend balance training as a core component of falls prevention programs for older people generally, as well as people with Mild Cognitive Impairment.

Falls in older ambulatory care patients with cancer in Iran: Implications for clinical practice

RATIONALE/AIM

Falls can have severe consequences particularly for older patients with cancer undergoing ambulatory care. The aim of the study is to identify the predictors of falls in older patients receiving cancer ambulatory care and evaluate the accuracy of the final multivariable model in detecting older patients with falls.

METHOD

A retrospective study was conducted on 300 older patients aged 60 years and above that were referred for ambulatory care in three oncology clinics based at hospitals in Tehran, Iran. Participants completed a questionnaire comprising demographic, history of falls, and cancer-related factors. Logistic regression was used to determine risk factors associated with falls.

RESULTS

A total of 35.3% of the older patients with cancer had experienced a fall in the 6 months following the start of their ambulatory care. The most important predictors of falls include the fourth stage of cancer (odds ratio [OR]: 6.47, 95% confidence interval [CI]: 3.20-13.08, p < 0.001), fear of falling (OR: 5.64, 95% CI: 2.58-12.33, p < 0.001), use of hearing (OR: 2.38, 95% CI: 1.07-5.29, p = 0.033) and visual aids (OR: 2.36, 95% CI: 1.12-5.01, p = 0.025), and the number of visits to the doctor (OR: 1.10, 95% CI: 1.01-1.21, p = 0.035).

CONCLUSIONS

The results indicate that a reduction in falls is possible by introducing strategies to improve care for older patients in the advanced stage of cancer, eliminating the causes of fear of falling, examining and improving vision and hearing, and identifying and addressing the underlying causes of visits to the doctor.

Comparisons of Fall Prevention Activities Using Electronic Nursing Records: A Case-Control Study

OBJECTIVE

The aim of this study was to compare the current fall prevention nursing practices with the evidence-based practices recommended in clinical practice guidelines according to the risk of falling and specific risk factors.

METHODS

The standardized nursing statements of 12,277 patients were extracted from electronic nursing records and classified into groups according to the risk of falling and individual patients' specific risk factors. The mean frequencies of the fall prevention practices in 10 categories derived from clinical practice guidelines were compared among the groups. We additionally analyzed the differences in the mean frequencies of tailored fall prevention practices according to individual patients' specific risk factors.

RESULTS

The nurses documented more fall prevention practices for patients at a high risk of falling and nonfallers than for patients at a low risk of falling and fallers. Specifically, the difference in nursing practices related to environmental modifications was largest between patients at a high risk of falling and those at a low risk of falling. There were also large differences in the nursing practices related to mental status, dizziness/vertigo, and mobility limitations between fallers and nonfallers. There was more documentation of tailored fall prevention practices related to mobility limitations for patient with mild lower limb weakness than for those with good power and balance. In contrast, patients with severe lower limb weakness had received fewer fall prevention practices related to mobility limitations.

CONCLUSIONS

The present findings emphasize that individual risk-specific nursing interventions in addition to universal precautions are crucial for preventing falls among patients.

Fear of falling and functional mobility in Elders with Diabetic Peripheral Neuropathy in Coastal Karnataka, India: A Hospital-Based Study

BACKGROUND

Aging with diabetic neuropathy is likely to predispose people to falls. Despite being a high-risk population, estimates of falls and their associated factors are poorly documented in elderly diabetic neuropathy patients living in coastal Karnataka, India.

OBJECTIVE

To investigate fear of falling and functional mobility, as an approximate measure of clinical fall risk, and explore the associated risk factors in elderly diabetic neuropathy patients living in coastal Karnataka, India.

METHOD

A hospital-based cross-sectional study on 316 elders aged 60 to 80 with diabetic neuropathy was conducted. A detailed diabetic foot evaluation was done. Self-reported fear of fall and functional mobility was measured using the Falls Efficacy Scale- International and Timed Up and Go test, respectively with published cut-points. Additionally, a recall of 12 months of fall history was recorded.

RESULTS

Descriptive analysis showed that self-reported fear of fall and below-average functional mobility was present in 39% and 49% of the elders with diabetic neuropathy, respectively. Spearman's correlational analysis revealed that self-reported fall concerns and functional mobility are significantly interdependent. Regression analysis suggested female gender, the severity of neuropathy, and previous falls as significant modifiers for fear of fall and poor functional mobility.

CONCLUSION

Half of the elders (49%) with diabetic neuropathy have poor functional mobility and 39% have a fear of falling. Improving physical function and addressing fall concerns of elders with diabetic neuropathy can result in greater confidence to participate in everyday activities and contribute to their better health. Hence, early fall risk identification is recommended for providing better health care in these individuals.

Prevalence of Fear of Falling and Its Association With Physical Function and Fall History Among Senior Citizens Living in Rural Areas of China

Background: Fear of falling (FOF) is as significant as a fall, leading to limited physical activity and poor quality of life among senior citizens. This study aimed to investigate the prevalence of FOF and its association with physical function and fall history among the senior citizens (≥75 years old) living in rural areas of China. Methods: This was a cross-sectional study conducted in eastern China from June to October 2019. All elderly participants were recruited during their attendance for the free health examinations in villages and towns organized by the local healthcare authorities. Data on sociodemographics, fall history, FOF conditions, self-reported comorbidity and regular medications were collected by face-to-face interview, and the physical function status was evaluated through a field test. Univariate and multivariate analyses were performed to compare the differences in physical function and fall history of senior citizens with/without FOF. Results: A total of 753 senior citizens (mean age = 79.04) participated in this study. Of these, 63.5% were aged 75-80. FOF was reported in 22.8% of the participants, while 18.5% had a fall in the past year. Among the senior citizens with and without a fall history, the prevalences of FOF were 38.8 and 19.2%, respectively. On multivariate analyses, FOF was independently associated with the Time Up and Go Test (TUG) duration (OR = 1.080; 95% CI: 1.034-1.128), 4-Stage Balance Test score (OR = 0.746; 95% CI: 0.597-0.931), fall history (OR = 2.633; 95% CI: 1.742-3.980), cerebral apoplexy (OR = 2.478; 95% CI: 1.276-4.813) and comorbidities (≥2) (OR = 1.637; 95% CI: 1.066-2.514), while the correlation between FOF and the 30-s chair stand test was only statistically significant in univariate analysis (Z = -3.528, p < 0.001). Conclusion: High prevalence of FOF is observed among the senior citizens living in rural areas of China. FOF is strongly correlated with physical function performance and fall history. Therefore, the implementation of targeted FOF prevention measures is key to improve the physical activity of the senior citizens, which would ultimately lead to fall prevention and improved quality of life.

Effectiveness of Olympic Combat Sports on Balance, Fall Risk or Falls in Older Adults: A Systematic Review

Simple Summary

The regular practice of physical activity has achieved greater diffusion in recent years as a strategy for fall prevention and improving or maintaining the general health status of older adults, which contributes to an active and healthy lifestyle. The strategies to promote active and healthy aging need to be reassessed due to the COVID-19 pandemic to promote the safe practice of physical activity among older adults, considering, among other measures, practicing social distancing or training at home. Such a scenario could provide the opportunity to promote physical activity that requires a limited number of participants in reduced spaces for its practice, such as Olympic combat sports. In this review, an overview of the effects of Olympic combat sports on balance, fall risk, or falls in older adults is presented. From 1496 records, eight studies were included, involving 322 older adults (64% female; mean age = 71.1 years). The available evidence does not allow a definitive recommendation for or against Olympic combat sports interventions as an effective strategy to improve balance and reduce the fall risk or falls in older adults. Therefore, more high-quality studies are required to draw definitive conclusions.

Abstract

This systematic review and meta-analysis aimed to assess the available body of published peer-reviewed articles related to the effects of Olympic combat sports (OCS), compared with active/passive controls, on balance, fall risk, or falls in older adults. The TESTEX and GRADE scales assessed the methodological quality and certainty of the evidence. The protocol was registered in PROSPERO (code: CRD42020204034). From 1496 records, eight studies were included, involving 322 older adults (64% female; mean age = 71.1 years). The TESTEX scale revealed all studies with a score ≥ 60% (moderate-high quality). The GRADE scale indicated all studies with at least some concerns, up to a high risk of bias (i.e., was rated very low). Meta-analyses were planned, although the reduced number of studies precluded its incorporation in the final manuscript. Only two from six studies that assessed balance found improvements after OCS compared to controls. No differences were found between OCS vs. control groups for fall risk or falls. The available evidence does not allow a definitive recommendation for or against OCS interventions as an effective strategy to improve balance and reduce the fall risk or falls in older adults. Therefore, more high-quality studies are required to draw definitive conclusions.

Perturbation-Based Balance Training Using Repeated Trips on a Walkway vs. Belt Accelerations on a Treadmill: A Cross-Over Randomised Controlled Trial in Community-Dwelling Older Adults

Background: Walkway and treadmill induced trips have contrasting advantages, for instance walkway trips have high-ecological validity whereas belt accelerations on a treadmill have high-clinical feasibility for perturbation-based balance training (PBT). This study aimed to (i) compare adaptations to repeated overground trips with repeated treadmill belt accelerations in older adults and (ii) determine if adaptations to repeated treadmill belt accelerations can transfer to an actual trip on the walkway.

Method: Thirty-eight healthy community-dwelling older adults underwent one session each of walkway and treadmill PBT in a randomised crossover design on a single day. For both conditions, 11 trips were induced to either leg in pseudo-random locations interspersed with 20 normal walking trials. Dynamic balance (e.g., margin of stability) and gait (e.g., step length) parameters from 3D motion capture were used to examine adaptations in the walkway and treadmill PBT and transfer of adaptation from treadmill PBT to a walkway trip.

Results: No changes were observed in normal (no-trip) gait parameters in both training conditions, except for a small (0.9 cm) increase in minimum toe elevation during walkway walks (P < 0.01). An increase in the margin of stability and recovery step length was observed during walkway PBT (P < 0.05). During treadmill PBT, an increased MoS, step length and decreased trunk sway range were observed (P < 0.05). These adaptations to treadmill PBT did not transfer to a walkway trip.

Conclusions: This study demonstrated that older adults could learn to improve dynamic stability by repeated exposure to walkway trips as well as treadmill belt accelerations. However, the adaptations to treadmill belt accelerations did not transfer to an actual trip. To enhance the utility of treadmill PBT for overground trip recovery performance, further development of treadmill PBT protocols is recommended to improve ecological authenticity.

Risk factors for accidental falls during pregnancy - a systematic literature review

INTRODUCTION

Falls during pregnancy occur in 25-27% of women and can cause serious harm to both the mother and the fetus. The objective of this systematic review was to identify intrinsic and extrinsic risk factors for falls during pregnancy by reviewing original studies and addressing possible forms of prevention.

METHODS

We searched PubMed, Cochrane library, and Web of Science databases for studies assessing risk factors for falling after a fall has occurred or by using posturographic assessment.

RESULTS

Fourteen studies were included in the review. The identified extrinsic risk factors include slippery floors, cluttered areas, uneven ground, inappropriate shoes, hurrying, walking on stairs, carrying additional loads, poor lighting or obstructed view, sedentary lifestyle and working in physically demanding jobs. The identified intrinsic factors include age less than 30, height more than 160 cm, advanced pregnancy, unintended pregnancy, multiparity, hyperemesis gravidarum, low back pain, gestational diabetes, increase in abdominal circumference, lower ankle stiffness and joint laxity. Physical activity, maternity support belts, and education are possible strategies for fall prevention.

CONCLUSION

Our systematic review identified 13 intrinsic and 11 extrinsic risk factors for falling during pregnancy. With the knowledge of risk factors and the optimal prevention strategy, healthcare providers could incorporate this information in the treatment of pregnant women and reduce the risk of falling.

Home Hazards With Fear of Falling: Findings From the Baseline Study of the Malaysian Elders Longitudinal Research (MELoR)

Background: Fear of falling (FoF) is a common issue among older people, impacting on psychological health, functional performance and mortality. Many factors associated with fear of falling have been investigated but little is known about the role of home hazards. Home hazards can be due to unsafe environmental and functional features. This study is aims to evaluate the association between home hazards with fear of falling among community-dwelling individuals aged 55 years and over.

Methods: Baseline data with 1,489 older individuals from the Malaysian Elders Longitudinal Research (MELoR) study were analyzed. Home visits for interview and observations in the home were conducted with the participants. FoF was established with a single-item question and home hazards with the Home Falls and Accidents Screening Tool (HOME FAST).

Results: The majority (76.4%) of older participants experienced FoF. The history of falls was not associated with FoF (p = 0.868), but FoF was associated with participants limiting their daily activities (p < 0.001). Home hazards were less likely (p = 0.023) and functional issues were more likely (p < 0.001) to be associated with a high degree of FoF. However, both home hazards domains were not associated with activity restriction due to FoF.

Conclusions: Education about home hazards from the perspective of person-environment interaction may encourage home hazards management and reduce FoF which should be evaluated in future studies.

Tai Chi for the Prevention of Falls Among Older Adults: A Critical Analysis of the Evidence

Despite interest as to the benefits of Tai Chi, there remains a controversy over its effectiveness as an exercise intervention for preventing falls among older adults. This review synthesizes the evidence base with a focus on meta-analyses and randomized controlled trials with community-dwelling older adults. It provides a critical lens on the evidence and quality of the trials. High-quality evidence suggests that Tai Chi is an effective intervention for preventing falls in community settings; however, there is unclear evidence for long-term care facilities and an absence of evidence for hospital settings. When compared directly with other exercise interventions, Tai Chi may offer a superior strategy for reducing falls through its benefits on cognitive functioning. Using data from the current Cochrane review, a new synthesis is presented suggesting that 71-81% of community-dwelling older adults are adherent to class-based Tai Chi interventions. The practical opportunities and challenges for practitioners are discussed.

[Elder fallers: A group at risk of readmission?]

OBJECTIVES

To describe older patients hospitalized for falls, at risk of readmission and priority for interventions to reduce this risk.

METHODS

We conducted an observational, monocentric, prospective study (from April to June 2019). The inclusion criteria were: patients aged 75 and over, admitted to the Emergency Department for falls, consenting to the study. For patients subsequently hospitalized, the geriatric scores were determined (risk of readmission [ISAR score], state of frailty, degree of autonomy [Katz score]), and when appropriate, medication treatments were listed and compliance of patients was assessed (Girerd score).

RESULTS

In three months, 154 patients were included (median age 86 years [min 75-max 103], sex ratio 0.44), of which 73 patients were hospitalized. Among these patients, 63% presented a high risk of readmission; 45.2% are likely to become frail; 72.6% were dependent. Finally, 53 of the 73 patients (72.6%) had a treatment in primary care and presented a 71.7% non-compliance or low-compliance rate. Fifty height patients (79.5%) had at least 1 drug associated with fall [min 1-max 7].

CONCLUSIONS

Older patients presenting at hospital with a fall were numerous, often likely to become frail and dependent for the majority of them. As the readmission risk is also very high in this population, future studies aiming at reducing the risk of hospital readmission are needed.

Readmissions of Elder Patients Presenting to Hospital for a Fall (RELIEF): A Systematic Review

OBJECTIVES

Falls are an important issue in older adults as they are frequent, deleterious, and often lead to repeated consultations at the emergency department (ED) and unplanned hospitalizations. Our principal objective was to provide an inventory of interventions designed to prevent unplanned readmissions or ED visits of older patients presenting to hospital with a fall.

DESIGN

Systematic review performed on February 11, 2019 in MEDLINE via PubMed, EMBASE, Cochrane Central Register of Controlled Trials, and Web of Science, without date or language restriction. We manually updated this search in August 1, 2019. Study selection, data extraction and risk of bias assessment were conducted independently by 2 reviewers.

SETTING AND PARTICIPANTS

We included studies reporting interventions to prevent unplanned readmissions or ED visits of older patients (aged 65 years or over) presenting to hospital because of a fall.

RESULTS

We identified 475 unique citations after removing duplicates and included 6 studies (2 observational and 4 interventional studies). The studies were published between 2012 and 2019; they evaluated heterogeneous interventions that were frequently multifaceted and multidisciplinary. The interventions were shown effective in reducing readmissions or ED revisits compared with control groups in 3 studies (relative risk reductions between 30% and 65%), all of which were multifaceted and 2/3 multidisciplinary.

CONCLUSIONS AND IMPLICATIONS

With 6 articles showing inconsistent results, our study highlights the need to adequately design and evaluate interventions to reduce the burden of hospital readmissions among older fallers. Retrieved studies are recent, which underlines that hospital readmissions are a current concern for researchers and public health authorities [PROSPERO registration number: CRD42019131965].

Fatal positional asphyxia following a fall in bathroom

A 27-year-old female student was found dead inside the bathroom of her university hostel. The body was in a prone position with her neck over-flexed on to her trunk. The medico-legal autopsy found features of asphyxia. Multiple lacerated wounds were present on the occipital region of scalp. The cause of death was opined as positional asphyxia following an accidental fall and blunt trauma to the head. In this case, concussion due to blunt trauma to the head may have precluded any self-rescue efforts by the victim from the floor leading to positional asphyxia.

Prevalence of Osteoporosis in Patients with Distal Radius Fracture from Low-Energy Trauma

Introduction: Osteoporosis is a devastating problem leading to significant morbidity and mortality. Patients with osteoporosis usually present with fractures from low-energy trauma and falls, commonly of the distal radius, which may precede more severe fractures like fracture of the neck of femur, but data from Thailand are limited. The objective of our study was to determine the prevalence of osteoporosis in patients with distal radius fracture from low-energy trauma. Materials and Methods: This was a descriptive retrospective study, performed at Thammasat University Hospital in Thailand, from January 2011 to June 2017. Patients aged more than 50 years with distal radial fractures from low-energy trauma with available bone mineral density (BMD) result were included. Patients with known secondary causes of osteoporosis were excluded. Patients were grouped by age, sex, and BMD status (normal, osteopenic and osteoporotic). Results: One hundred out of 351 patients with distal radial fractures had bone mineral density data but only 79 (73 females) met the inclusion criteria. Most patients were aged 60-69 years old (n=31, 42.5%). 47 (59.5%) patients were osteoporotic, 23 (29.1%) osteopenic, and 9 (11.4%) were normal. Seven (6 osteoporotic) patients suffered a more severe fracture subsequently. No deaths were recorded. Conclusion: Our study found a high rate of osteoporosis mostly in females, consistent with published literature. Assessing BMD is crucial in middle age and elderly patients with fractures to better manage osteoporosis and prevent more severe fractures in the future.

Fall-risk increasing drugs and recurrent injurious falls association in older patients after hip fracture: a cohort study protocol

Polypharmacy and fall-risk increasing drugs (FRIDS) have been associated with injurious falls. However, no information is available about the association between FRIDS and injurious falls after hospital discharge due to hip fracture in a very old population. We aim to assess the association between the use of FRIDS at discharge and injurious falls in patients older than 80 years hospitalized due to a hip fracture. A retrospective cohort study using routinely collected health data will be conducted at the Orthogeriatric Unit of a teaching hospital. Patients will be included at hospital discharge (2014), with a 2-year follow-up. Fall-risk increasing drugs will be recorded at hospital discharge, and exposure to drugs will be estimated from usage records during the 2-year follow-up. Injurious falls are defined as falls that lead to any kind of health care (primary or specialized care, including emergency department visits and hospital admissions). A sample size of 193 participants was calculated, assuming that 40% of patients who receive any FRID at discharge, and 20% who do not, will experience an injurious fall during follow up. This protocol explains the study methods and the planned analysis. We expect to find a relevant association between FRIDS at hospital discharge and the incidence of injurious falls in this very old, high risk population. If confirmed, this would support the need for a careful pharmacotherapeutic review in patients discharged after a hip fracture. However, results should be carefully interpreted due to the risk of bias inherent to the study design.

Diagnostic test accuracy of an automated device as a screening tool for fall risk assessment in community-residing elderly: A STARD compliant study

We aimed to determine the accuracy and failure of OAK device, an automated screening, for the assessment of fall risk in a prospective cohort of healthy adults aged over 65 years. The algorithm for fall risk assessment of the centers for disease control and prevention (CDC) was used as reference standard. Of the 183 individuals recruited, the CDC algorithm classified 80 as being at moderate/high risk and 103 at low risk of falling. OAK device failure incidence was 4.9% (confidence interval [CI] upper limit 7.7%), below the preset threshold for futility-early termination of the study (i.e., not above 15%). The OAK device showed a sensitivity of 84% and a specificity of 67% (receiver operating characteristic [ROC] area 82%; 95% confidence interval [CI] 76-88%), not reaching the preplanned target sensitivity (not lower than 85%). Diagnostic accuracy was not far from the sensitivity levels similar to those obtained with other fall risk assessment. However, some limitations can be considered.ClinicalTrials.gov identifier: NCT02655796.

[Management and orientation of geriatric patients admitted to emergencies for a fall: results of the French prospective OREGoN cohort study]

Falls in older adults are a frequent reason for admission to the emergency department, associated with greater morbidity and mortality risks, and justify specialized geriatric expertise. Our objective was to determine i) the number of older fallers admitted to the emergency department for a serious fall, and ii) the proportion of those who were referred to a geriatrician in the following 12 months.

METHODS

We included all patients aged 75 and over admitted to the emergency department of the University hospital of Angers, France, for a fall between 1st October and 1st November 2015. The consensual criteria proposed by the French national authority for health (2009) were used to define serious falls.

RESULTS

Of the 214 older fallers admitted to the emergency department, 213 (99.5%) had at least one severity criterion for the fall. Only 40 older patients (18.7%) were referred to a geriatrician during the following 12 months. They exhibited more frequently a post-fall syndrome (p=0.007), more than 3 fall risk factors (p <0.001), and took more often an anticoagulant (p=0.032) than those who had not been referred to a geriatrician.

CONCLUSIONS

Although almost all older fallers admitted to the emergency room had experienced a serious fall, only a minority of them received a geriatric assessment in the following year.

Characteristics of fall-related traumatic brain injury in older adults

BACKGROUND

Older adults admitted for falls and its complications, including traumatic brain injury (TBI), is increasing. Recent studies have shown that those with falls who presented to the emergency department (ED) had an increased frequency of ED revisits, especially those with head trauma.

AIM

To determine the characteristics and predictors of fall-related traumatic brain injury (FRTBI) in older adults.

METHODS

Retrospective medical chart review of 339 patients aged 65 years and older admitted for TBI in 2014 due to a fall. Characteristics analysed include demographics, fall circumstances, prior ED visits, polypharmacy, readmission, functional status and specialist outpatient clinic utilisation before and after FRTBI.

RESULTS

A total of 339 (37.4%) patients admitted due to FRTBI was 65 years old and older; 112 (33.0%) for subdural haemorrhage (SDH); 227 (67.0%) for head injury (HI), with a mean age of 80 years. A total of 46 (41.1%) patients with SDH and 107 (47.1%) with HI had a previous ED visit within the last year, while 22 (19.6%) of SDH and 49 (21.6%) of HI had hospitalisation 3 months prior to FRTBI. FRTBI was associated with significant decline in activities of daily living, polypharmacy and increased specialist outpatient clinic appointments (P < 0.001). Mortality was 11 (3.2%). Mild cognitive impairment or dementia was significantly associated with admissions for FRTBI, 3.31 (95% confidence interval 1.68-6.51, P = 0.001) using adjusted logistic regression.

CONCLUSION

FRTBI is associated with significant functional decline and increased resource utilisation with almost half of the patients having had prior ED visits or hospitalisation. Future studies should focus on falls risk assessment and interventions for high-risk older adults prior to discharge from ED and hospital, and its impact on readmissions due to FRTBI.

Differentiation between suicidal and accidental falls from height using the method proposed by Teh et al

One of the main problems encountered in medico-legal assessment of injuries suffered as a result of falling from a height is the discrimination between the effects of accidental and suicidal falls. The aim of the study was to verify the prevalence of injuries involving different regions of the osteoarticular system in groups of victims of attempted suicide and fatal accidents according to the method proposed by Teh et al. The study material consisted of the findings of extended post-mortem examinations of 114 victims of falls from a height, which were conducted in the Department of Forensic Medicine in Lublin. The post-mortem results were compared with the data found in corresponding prosecutorial case files. The results of the study indicate a higher prevalence of osteoarticular injuries within the pelvis and lower limbs in the group of suicide victims, which correlates with the results reported by Teh et al. An analysis of injuries in different body regions in accordance with the reported method can be useful in determining the circumstances of falling from a height.

An Initial Passive Phase That Limits the Time to Recover and Emphasizes the Role of Proprioceptive Information

In the present experiments, multiple balance perturbations were provided by unpredictable support-surface translations in various directions and velocities. The aim of this study was to distinguish the passive and the active phases during the pre-impact period of a fall. It was hypothesized that it should be feasible if one uses a specific quantitative kinematic analysis to evaluate the dispersion of the body segments trajectories across trials. Moreover, a multi-joint kinematical model was created for each subject, based on a new 3-D minimally invasive stereoradiographic X-ray images to assess subject-specific geometry and inertial parameters. The simulations allowed discriminating between the contributions of the passive (inertia-induced properties) and the active (neuromuscular response) components during falls. Our data show that there is limited time to adjust the way one fall from a standing position. We showed that the pre-impact period is truncated of 200 ms. During the initial part of a fall, the observed trajectory results from the interaction between the destabilizing external force and the body: inertial properties intrinsic to joints, ligaments and musculotendinous system have then a major contribution, as suggested for the regulation of static upright stance. This passive phase is later followed by an active phase, which consists of a corrective response to the postural perturbation. We believe that during a fall from standing height, it takes about 300 ms for postural responses to start correcting the body trajectory, while the impact is expected to occur around 700 ms. It has been argued that this time is sufficient to change the way one falls and that this makes it possible to apply safer ways of falling, for example by using martial arts fall techniques. Also, our results imply visual and vestibular information are not congruent with the beginning of the on-going fall. This consequence is to be noted as subjects prepare to the impact on the basis of sensory information, which would be uniquely mainly of proprioceptive origin at the fall onset. One limitation of the present analysis is that no EMG was included so far but these data are the subject of a future study.

Environmental and physical factors predisposing middle-aged and older Japanese adults to falls and fall-related fractures in the home

AIM

To identify environmental and physical factors that predispose middle-aged and older Japanese adults to falls and fall-related fractures in the home.

METHODS

A cross-sectional survey was carried out in 2014. Self-administered questionnaires were distributed to 15 000 community-dwelling adults in Japan. The overall crude response rate was 13%. Response data were analyzed from 1561 individuals aged ≥40 years using multiple imputation to analyze missing data. We evaluated falls without fractures and fall-related fractures during the previous 3 years according to demographic, physical and environmental factors, including age, sex, long-term care insurance certification, type of house and barrier-free housing.

RESULTS

Of the 1561 adults (mean age 68.1 ± 13.0 years), 28% experienced a fall in the home. Among the individuals who experienced a fall, 11% experienced fall-related fractures. These individuals were more likely to be women (OR 2.4, 95.0% CI 1.1-5.1), have LTCI certification (OR 3.9, 95.0% CI 1.6-9.4) and be living in a barrier home (OR 4.0, 95.0% CI 1.6-9.8), after adjustment for covariates.

CONCLUSIONS

Environmental factors, such as living in a barrier home, are critical for fall-related fractures, in addition to demographic and physical factors. A multidisciplinary approach that considers both physical and environmental factors is necessary for reducing the incidence of fall-related fractures among middle-aged and older Japanese adults.

Testing the Predictive Validity of the Hendrich II Fall Risk Model

Cumulative data on patient fall risk have been compiled in electronic medical records systems, and it is possible to test the validity of fall-risk assessment tools using these data between the times of admission and occurrence of a fall. The Hendrich II Fall Risk Model scores assessed during three time points of hospital stays were extracted and used for testing the predictive validity: (a) upon admission, (b) when the maximum fall-risk score from admission to falling or discharge, and (c) immediately before falling or discharge. Predictive validity was examined using seven predictive indicators. In addition, logistic regression analysis was used to identify factors that significantly affect the occurrence of a fall. Among the different time points, the maximum fall-risk score assessed between admission and falling or discharge showed the best predictive performance. Confusion or disorientation and having a poor ability to rise from a sitting position were significant risk factors for a fall.

Characteristics, consequences and prevention of falls in institutionalised older adults in the province of Malaga (Spain): a prospective, cohort, multicentre study

OBJECTIVES

Falls are an important adverse event among institutionalised persons. It is in this clinical setting where falls occur more frequently than in any other, despite the measures commonly taken to prevent them. This study aimed to determine the characteristics of a typical institutionalised elderly patient who suffers a fall and to describe the physical harms resulting from this event. We then examined the association between falls and the preventive measures used.

METHODS

This was a prospective cohort study in 37 nursing homes in Spain. The participants were all the nursing home residents institutionalised in these centres from May 2014 to July 2016. Participants were followed up for 9 months. During this period, two observations were made to evaluate the preventive measures taken and to record the occurrence of falls.

RESULTS

896 residents were recruited, of whom 647 completed the study. During this period, 411 falls took place, affecting 213 residents. The injuries caused by the falls were mostly minor or moderate. They took place more frequently among women and provoked 22 fractures (5.35%). The most commonly used fall prevention measure was bed rails (53.53% of cases), followed by physical restraint (16.79%). The latter measure was associated with a higher incidence of injuries not requiring stitches (OR=2.06, 95% CI 1.01 to 4.22, P=0.054) and of injuries that did require stitches (OR=3.51, 95% CI 1.36 to 9.01, P=0.014) as a consequence of falls. Bed rails protected against night-time falls.

CONCLUSIONS

Falls are a very common adverse event in nursing homes. The prevention of falls is most commonly addressed by methods to restrain movement. The use of physical restraints is associated with a greater occurrence of injuries caused by a fall.

Comparison of Walking, Muscle Strength, Balance, and Fear of Falling Between Repeated Fall Group, One-time Fall Group, and Nonfall Group of the Elderly Receiving Home Care Service

PURPOSE

The purpose of this study was to provide information to develop a program to prevent repeated falls by analyzing the difference in gait, muscle strength, balance, and fear of falling according to their fall experience.

METHODS

The study subjects were 110 elderly individuals aged over 60 years who agreed to their participation in this research. The study participants were categorized into a repeated fall group (n = 40), a one-time fall group (n = 15), and a nonfall group (n = 46) of the elderly. Measurements of gait, muscle strength, balance, and fear of falling were taken in each group.

RESULTS

With regard to gait, there were significant differences among three groups in gait cycle (F = 3.50, p = .034), speed (F = 13.06, p < .001), and cadence (F = 5.59, p = .005). Regarding muscle strength in the upper and lower limbs, statistically significant differences were shown among three groups in muscle strength of upper (F = 16.98, p < .001) and lower (F = 10.55, p < .001) limbs. With regard to balance, the nonfall group had significantly greater results than the one-time fall group and repeated fall group in dynamic balance (F = 10.80, p < .001) and static balance (F = 8.20, p = .001). In the case of the fear of falling, the repeated fall group had significantly higher score than other two groups (F = 20.62, p < .001).

CONCLUSION

This study suggests that intervention program should be tailored to fall risk factors to enhance gait and balance and lower body muscle strength and reduce the fear of falling to prevent repeated incidences of falls in this population.

Study of fall risk-increasing drugs in elderly patients before and after a bone fracture

BACKGROUND

Accidental falls have a significant economic and human impact. The use of certain drugs is one of the modifiable risk factors associated with these events.

OBJECTIVE

The aim of this study was to determine the prevalence of use and to explore changes in treatment with fall-related drugs in patients over 65 years of age admitted as a result of a fall-related fracture.

METHODS

Observational and prospective study performed in a tertiary level hospital. A list of fall risk-increasing drugs (FRIDs) was drawn up. The main study variables were number and type of FRIDs prescribed at admission and 1 month after the fracture and number, type, treating physician and place where changes in FRIDs were implemented.

RESULTS

In total, 252 patients were included. At admission, 91.3% were receiving at least one FRID, mean daily use was 3.1 FRIDs and the most frequently prescribed FRIDs were diuretics (18%), renin-angiotensin system-acting agents (15.8%) and antidepressants (15%). One month later, mean daily use was 3.4 FRIDs (p=0.099) and a significant increase was detected in the use of hypnotics (p=0.003) and antidepressants (p=0.042). A total of 327 changes in treatment were recorded (1.3 changes/patient). Of the changes, 52.6% were new prescriptions, 72.2% occurred at discharge and 56.6% were ordered by a geriatrician.

CONCLUSIONS

The use of FRIDs among patients with a fall-related fracture is very high. This use rises 1 month after the fracture, significantly in the case of hypnotics and antidepressants.

Fall frequency and associated factors among men and women with or at risk for HIV infection

OBJECTIVES

Falls and fall-related injuries are a major public health concern. HIV-infected adults have been shown to have a high incidence of falls. Identification of major risk factors for falls that are unique to HIV infection or similar to those in the general population will inform development of future interventions for fall prevention.

METHODS

HIV-infected and uninfected men and women participating in the Hearing and Balance Substudy of the Multicenter AIDS Cohort Study and Women's Interagency HIV Study were asked about balance symptoms and falls during the prior 12 months. Falls were categorized as 0, 1, or ≥ 2; proportional odds logistic regression models were used to investigate relationships between falls and demographic and clinical variables and multivariable models were created.

RESULTS

Twenty-four per cent of 303 HIV-infected participants reported at least one fall compared with 18% of 233 HIV-uninfected participants (P = 0.27). HIV-infected participants were demographically different from HIV-uninfected participants, and were more likely to report clinical imbalance symptoms (P ≤ 0.035). In univariate analyses, more falls were associated with hepatitis C, female sex, obesity, smoking, and clinical imbalance symptoms, but not age, HIV serostatus or other comorbidities. In multivariable analyses, female sex and imbalance symptoms were independently associated with more falls. Among HIV-infected participants, smoking, a higher number of medications, and imbalance symptoms remained independent fall predictors, while current protease inhibitor use was protective.

CONCLUSIONS

Similar rates of falls among HIV-infected and uninfected participants were largely explained by a high prevalence of imbalance symptoms. Routine assessment of falls and dizziness/imbalance symptoms should be considered, with interventions targeted at reducing symptomatology.

Clinical differences among the elderly admitted to the emergency department for accidental or unexplained falls and syncope

It is difficult to distinguish unexplained falls (UFs) from accidental falls (AFs) or syncope in older people. This study was designed to compare patients referred to the emergency department (ED) for AFs, UFs or syncope. Data from a longitudinal study on adverse drug events diagnosed at the ED (ANCESTRAL-ED) in older people were analyzed in order to select cases of AF, syncope, or UF. A total of 724 patients (median age: 81.0 [65-105] years, 66.3% female) were consecutively admitted to the ED (403 AF, 210 syncope, and 111 UF). The number of psychotropic drugs was the only significant difference in patients with AF versus those with UF (odds ratio [OR] 1.44; 95% confidence interval 1.17-1.77). When comparing AF with syncope, female gender, musculoskeletal diseases, dementia, and systolic blood pressure >110 mmHg emerged as significantly associated with AF (OR 0.40 [0.27-0.58], 0.40 [0.24-0.68], 0.35 [0.14-0.82], and 0.31 [0.20-0.49], respectively), while valvulopathy and the number of antihypertensive drugs were significantly related to syncope (OR 2.51 [1.07-5.90] and 1.24 [1.07-1.44], respectively). Upon comparison of UF and syncope, the number of central nervous system drugs, female gender, musculoskeletal diseases, and SBP >110 mmHg were associated with UF (OR 0.65 [0.50-0.84], 0.52 [0.30-0.89], 0.40 [0.20-0.77], and 0.26 [0.13-0.55]), respectively. These results indicate specific differences, in terms of demographics, medical/pharmacological history, and vital signs, among older patients admitted to the ED for AF and syncope. UF was associated with higher use of psychotropic drugs than AF. Our findings could be helpful in supporting a proper diagnostic process when evaluating older patients after a fall.

The Effectiveness of a Wireless Modular Bed Absence Sensor Device for Fall Prevention among Older Inpatients

Background

Falls and fall-related injuries are increasingly serious issues among elderly inpatients due to population aging. The bed-exit alarm has only previously been evaluated in a handful of studies with mixed results. Therefore, we evaluated the effectiveness of a modular bed absence sensor device (M-BAS) in detecting bed exits among older inpatients in a middle income nation in East Asia.

Methods

Patients aged ≥65 years on an acute geriatric ward who were able to mobilize with or without walking aids and physical assistance were recruited to the study. The total number of alarms and the numbers of true and false alarms were recorded by ward nurses. The M-BAS device is placed across the mattress of all consenting participants. Nurses’ workload was assessed using the National Aeronautics and Space Administration-Task Load Index (NASA-TLX) score, while nurses’ perceptions were surveyed.

Results

The sensitivity of the M-BAS was 100% with a positive predictive value of 68% and a nuisance alarm rate of 31%. There was a significant reduction in total NASA-TLX workload score (mean difference = 14.34 ± 13.96 SD, p < 0.001) at the end of the intervention period. 83% of the nurses found the device useful for falls prevention, 97% found it user friendly, and 87% would use it in future.

Conclusion

The M-BAS was able to accurately detect bed absence episodes among geriatric inpatients and alert nurses accordingly. The use of the device significantly reduced the total workload score, while the acceptability of the device was high among our nurses. A larger, cluster randomized study to measure actual falls outcome associated with the use of the device is now indicated.

Bicycle helmet use to reduce the impact of head injuries in ladder users

BACKGROUND

The aim of this study was to determine if wearing a bicycle helmet during ladder use could reduce the incidence and severity of head injury in the event of a fall.

METHODS

A headform model with inbuilt accelerometers was used to determine the Head Injury Criterion (HIC) score of head impact by dropping 41 helmeted and unhelmeted headforms from eight heights. These results were compared.

RESULTS

There was a statistically significant difference between averaged HIC scores in helmeted and unhelmeted drops (P < 0.001). Unhelmeted HIC scores ranged from 387 at 0.25 m to 2121 at 0.6 m. Helmeted HIC scores ranged from 29 at 0.25 m to 1199 at 2.5 m. At a height of 0.5 m, the risk of severe brain injury (AIS ≥4) from direct frontal head impact is predicted to reduce from >50% to <5% with helmet use.

CONCLUSION

There was a significant decrease in the HIC scores when helmets are used and it is likely that the benefits would be seen in the clinical setting. These results provide an argument for the use of a bicycle helmets by all ladder users, in particular those over age 50 who are at increased risk of head injuries. We recommend that bicycle helmet use be incorporated into ladder injury prevention strategies.

Occupational fall injuries presenting to the emergency department

OBJECTIVES

This study was performed to evaluate occupational and fall injuries presenting to the ED, the risk factors associated with falls among all occupational injuries, and factors affecting prognosis.

METHODS

Data from ED-based Occupational Injury Surveillance System were analysed to investigate the occupational injuries. The 2147 occupational injury subjects were divided into two groups: fall (n = 213, 9.9%) and non-fall (n = 1934, 90.1%). Data including baseline and clinical characteristics were compared between the groups.

RESULTS

The mean age was older in the fall group (46 vs 42 years old). The rate of construction site-related injury was 32% in the fall group and only 8% in the non-fall group. Injury occurrence during regular working hours (09.00 hours to 18.00 hours) was 70% in the fall group and 57% in the non-fall group. Injury severity using the Excess Mortality Ratio-adjusted Injury Severity Score (EMR-ISS) was more severe in the fall group than in the non-fall group, and days away from work were longer in the fall group than the non-fall group. Older age, compared with an age <29 years old and presence in a construction area during regular working hours were factors associated with fall injuries. Factors affecting prolonged absence for work were older age, higher EMR-ISS, fall injury and poor workplace environmental conditions.

CONCLUSION

Risk factors associated with fall-related occupational injuries include older age and being at a construction area during regular working hours. Falls among occupational injuries are more severe than other injuries and result in longer work loss.

Validity of the Morse Fall Scale implemented in an electronic medical record system

AIMS AND OBJECTIVES

To examine the validity of the Morse Fall Scale by analysing the electronic medical records on fall risk during different phases of hospitalisation.

BACKGROUND

Regular monitoring on fall risk with a reliable and valid assessment tool is a key element in the fall prevention. In Korea, the Morse Fall Scale is currently being used in numerous medical institutions, yet it has not been comprehensively evaluated whether it is suitable and valid.

DESIGN

The study design was a retrospective case-control study.

METHODS

The participants included 151 fallers and 694 nonfallers. Data were extracted from a university hospital implementing Morse Fall Scale in the electronic medical records between October 2010 and June 2011. The nonfallers were selected by the stratified random sampling method among the patients who were in the hospital during the same period as the fallers. The Morse Fall Scale scores during three different time periods of hospital stay were used for analysis: the initial assessment score upon admission, the last and the maximum scores recorded from admission to the fall or discharge.

RESULTS

With the maximum Morse Fall Scale score and the best cut-off point of 51, validity indicators showed the highest performance: 0·72 for sensitivity, 0·91 for specificity, 0·63 for positive predictive value, 0·94 for negative predictive value, 0·63 for Youden Index and 0·77 for the area under the receiver operating characteristic curve.

CONCLUSION

The Morse Fall Scale showed relatively high predictive performance for the Korean population.

RELEVANCE TO CLINICAL PRACTICE

The study results recommend practice change in fall prevention. As the validity was highest when the patient was first classified into the high-risk group based on the Morse Fall Scale cut-off score 51, patients classified as high risk should be placed under special nursing interventions until the day of their discharge, regardless of change in the patient state.
