Interventions for preventing falls in older people in care facilities and hospitals

Patient safety is our business! Staff perspectives on implementing hospital falls prevention education

Providing patients with falls prevention education reduces falls in hospitals, yet there is limited research on what influences successful implementation at the staff, ward and hospital levels. We engaged hospital-based health professionals to identify multi-level barriers and enablers to patient falls education that could influence the implementation of a Safe Recovery program. Purposive sampling was used to recruit hospital staff (n = 40) for focus groups and one-on-one interviews. Data were analysed using content analysis and categorized using a socio-ecological framework to understand the micro, meso and macro level influences of hospital falls prevention. We identified five overarching themes, on the barriers and enablers to implementation of the Safe Recovery program. The enablers to falls prevention education included sharing the responsibility to implement the program, setting clear goals for staff, showing the impact of delivering the program, involving family to reinforce the messaging, using falls champions to upskill staff and making the resources (video and booklet) readily available to patients at all times. Barriers included insufficient time for staff to deliver falls prevention education, lack of falls prevention training for staff during their clinical training, absence of standardized protocols and clinical guidelines across hospital settings and insufficient hospital marketing to promote the program. Using a systems thinking approach, this study showed that implementation requires more advocacy and support for patient falls prevention across different tiers of the hospital system to integrate into usual care.

Vitamin D deficiency in hip fracture patients is associated with an increased mortality risk

PURPOSE

The aims were to assess whether vitamin D deficiency influenced mortality risk and length of acute hospital stay in patients presenting with a hip fracture.

METHODS

A retrospective study was undertaken including all patients aged over 50 years that were admitted with a hip fracture to a single centre during a 24-month period. Serum vitamin D levels on admission, patient demographics, perioperative variables and mortality were collected. Cox regression analysis was utilised to determine the independent association between serum vitamin D levels and patient mortality.

RESULTS

The cohort consisted of 1510 patients with a mean age of 81.3 years and 1107 (71.4%) were female. 876 (58.0%) were vitamin D deficient (< 50 nmol/l). The median follow up was 405 (IQR 249 to 610) days. During follow-up there were 464 deaths (30.7%). Vitamin D deficiency was independently associated with higher mortality risk (hazard ratio [HR] 1.26, 95% confidence interval (CI) 1.03 to 1.53, P = 0.022). Male sex (HR 1.64, 95% CI 1.34 to 2.01, P < 0.001) was also associated with a higher mortality risk. Vitamin D deficiency was not associated with length of hospital stay (median difference 0 days, P = 0.207).

CONCLUSION

Vitamin D deficiency was independently associated with increased mortality in hip fracture patients, though this finding may be influenced by lack of comprehensive adjustment for comorbidity. While the value of routine serum vitamin D measurement is debated, supplementation during hospital stays is important to reduce falls and fracture risks associated with deficiency.

Relationship Between Unit Characteristics and Fall Incidence: A Cross-Sectional Survey Using Administrative Data in Japan

BACKGROUND

Falls are the most frequent accident experienced by inpatients in hospitals. As falls affect patient outcomes, high fall risk factors should be studied to prevent falls and improve patient safety. However, the relationship between hospital unit characteristics and fall risk has never been assessed.

PURPOSE

This study was designed to identify the unit characteristics significantly related to fall risk.

METHODS

A cross-sectional study was conducted on the medical records of patients hospitalized in a Japanese academic hospital between 2018 and 2019. This study quantified unit activities and utilized Diagnosis Procedure Combination data to examine unit characteristics related to falls based on unit day.

RESULTS

Data on 16,307 patients were included in the analysis, and 355 unit days were certified as fall events. Based on patient condition and medical treatment, the results identified antineoplastic injections, radiation therapy, aseptic treatment room, and functional status of partly assisted transfers, meals, and oral care as unit characteristics associated with increased fall events. Decreased nursing time per patient at night (odds ratio [OR] = 0.75, p = .04) and higher numbers of partially assisted transfer patients were also identified as unit characteristics associated with higher fall incidence rates (OR = 5.56, p = .01).

CONCLUSIONS

The results of this study are expected to assist nurses to predict falls based on unit characteristics; reducing nursing time in the units was found to be a factor associated with higher fall risk. Nurse managers must understand the unit-related fall risk factors, appropriately assign nurse staffing numbers, and demonstrate nursing leadership to prevent falls in their units.

Improving Neurology Inpatient Fall Rate: Effect of a Collaborative Interdisciplinary Quality Improvement Initiative

Objective

To reduce unwitnessed inpatient falls on the neurology services floor at an academic medical center by 20% over 15 months.

Patients and Methods

A 9-item preintervention survey was administered to neurology nurses, resident physicians, and support staff. Based on survey data, interventions targeting fall prevention were implemented. Providers were educated during monthly in-person training sessions regarding the use of patient bed/chair alarms. Safety checklists were posted inside each patient's room reminding staff to ensure that bed/chair alarms were on, call lights and personal items were within reach, and patients' restroom needs were addressed. Preimplementation (January 1, 2020, to March 31, 2021) and postimplementation (April 1, 2021, to June 31, 2022) rates of falls in the neurology inpatient unit were recorded. Adult patients hospitalized in 4 other medical inpatient units not receiving the intervention served as a control group.

Results

Rates of falls, unwitnessed falls, and falls with injury all decreased after intervention in the neurology unit, with rates of unwitnessed falls decreasing by 44% (2.74 unwitnessed falls per 1000 patient-days before intervention to 1.53 unwitnessed falls per 1000 patient-days after intervention; P=.04). Preintervention survey data revealed a need for education and reminders on inpatient fall prevention best practices given a lack of knowledge on how to operate fall prevention devices, driving the implemented intervention. All staff reported significant improvement in operating patient bed/chair alarms after intervention (P<.001).

Conclusion

A collaborative, multidisciplinary approach focusing on provider fall prevention education and staff checklists is a potential technique to reduce neurology inpatient fall rates.

[Fall prevention in old people through occupational therapy home assessment, consultation and modification: a process outline]

Falls occur frequently in old people and are associated with relevant short-term and long-term trauma sequelae. Particularly in the light of demographic change, preventive measures such as falls prevention are increasingly gaining in importance. Occupational therapy home assessments enable the evaluation of external and behavioral risk factors for falls in the context of environmental prevention. Environmental prevention is an effective measure in preventing morbidity and mortality related to falls in old people and the increase in healthcare costs associated with falls. Occupational therapy home assessments effectively reduce fall risk and fall rate among older people at risk of falling and can be implemented in the context of existing regulatory frameworks. The aim of this overview is to illustrate the optimal process of home assessment and adaptation for patients at risk of falling by general practitioners, orthopedic surgeons and occupational therapists.

How do healthcare providers use national audit data for improvement?

BACKGROUND

Substantial resources are invested by Health Departments worldwide in introducing National Clinical Audits (NCAs). Yet, there is variable evidence on the NCAs' effectiveness and little is known on factors underlying the successful use of NCAs to improve local practice. This study will focus on a single NCA (the National Audit of Inpatient Falls -NAIF 2017) to explore: (i) participants' perspectives on the NCA reports, local feedback characteristics and actions undertaken following the feedback underpinning the effective use of the NCA feedback to improve local practice; (ii) reported changes in local practice following the NCA feedback in England and Wales.

METHODS

Front-line staff perspectives were gathered through interviews. An inductive qualitative approach was used. Eighteen participants were purposefully sampled from 7 of the 85 participating hospitals in England and Wales. Analysis was guided by constant comparative techniques.

RESULTS

Regarding the NAIF annual report, interviewees valued performance benchmarking with other hospitals, the use of visual representations and the inclusion of case studies and recommendations. Participants stated that feedback should target front-line healthcare professionals, be straightforward and focused, and be delivered through an encouraging and honest discussion. Interviewees highlighted the value of using other relevant data sources alongside NAIF feedback and the importance of continuous data monitoring. Participants reported that engagement of front-line staff in the NAIF and following improvement activities was critical. Leadership, ownership, management support and communication at different organisational levels were perceived as enablers, while staffing level and turnover, and poor quality improvement (QI) skills, were perceived as barriers to improvement. Reported changes in practice included increased awareness and attention to patient safety issues and greater involvement of patients and staff in falls prevention activities.

CONCLUSIONS

There is scope to improve the use of NCAs by front-line staff. NCAs should not be seen as isolated interventions but should be fully embedded and integrated into the QI strategic and operational plans of NHS trusts. The use of NCAs could be optimised, but knowledge of them is poor and distributed unevenly across different disciplines. More research is needed to provide guidance on key elements to consider throughout the whole improvement process at different organisational levels.

Clinical Sensor-Based Fall Risk Assessment at an Orthopedic Clinic: A Case Study of the Staff's Views on Utility and Effectiveness

In-hospital falls are a serious threat to patient security and fall risk assessment (FRA) is important to identify high-risk patients. Although sensor-based FRA (SFRA) can provide objective FRA, its clinical use is very limited and research to identify meaningful SFRA methods is required. This study aimed to investigate whether examples of SFRA methods might be relevant for FRA at an orthopedic clinic. Situations where SFRA might assist FRA were identified in a focus group interview with clinical staff. Thereafter, SFRA methods were identified in a literature review of SFRA methods developed for older adults. These were screened for potential relevance in the previously identified situations. Ten SFRA methods were considered potentially relevant in the identified FRA situations. The ten SFRA methods were presented to staff at the orthopedic clinic, and they provided their views on the SFRA methods by filling out a questionnaire. Clinical staff saw that several SFRA tasks could be clinically relevant and feasible, but also identified time constraints as a major barrier for clinical use of SFRA. The study indicates that SFRA methods developed for community-dwelling older adults may be relevant also for hospital inpatients and that effectiveness and efficiency are important for clinical use of SFRA.

Associations of Household Solid Fuel Use With Falls and Fall-Related Injuries in Middle-Aged and Older Population in China: A Cohort Study

Objective: This study evaluated the associations of solid fuels with incidence of falls and fall-related injuries. Methods: Data were taken from wave 1∼4 of the China Health and Retirement Longitudinal Study, including 15,651 participants aged 45 years and older. Modified Poisson regression was used to examine the associations of solid fuels with falls and fall-related injuries. Results: Modified Poisson regression analysis showed that solid fuels users for cooking had an increasing incidence of falls and fall-related injuries, with RR of 1.211 (95% CI: 1.124, 1.305) and 1.248 (95% CI: 1.107, 1.408); for heating had an incidence, with RR of 1.178 (95% CI: 1.062, 1.306) and 1.134 (95% CI: 0.963, 1.335); combined for cooking and heating, with RR of 1.247 (95% CI: 1.105, 1.408) and 1.185 (95% CI: 0.982, 1.431). Conclusion: Our study suggests that solid fuel use is associated with a higher incidence of falls and fall-related injuries among adults aged 45 years and older in China. It is necessary to restrict solid fuel use to reduce household air pollution and make stronger environmental protection policies to improve household environment.

The costs of care: An ethnography of care work in residential homes for older people

The cost of social care, the work conditions experienced by care workers and the quality of care provided by residential homes for older people are all linked, yet we know very little about how this relationship works in practice. Drawing upon an ethnography of two differently priced residential care homes for older people in Southern England, I examine the implications of different financial regimes for care-giving practices. I show how the scheduling and allocation of resources-conveyed, for example, in formal routines and staffing levels-structure the care workers' time, tasks and activities in each setting. This acts to symbolically demarcate what, or who, is valued. I argue that the availability of resources facilitates and impedes the symbolic culture of care work, shapes care workers' ability to afford dignity to the individuals in their care and affects how care workers experience, and relate to, their labour. I conclude by discussing how current practices of funding and pricing social care have effects seeping beyond the practical and measurable, and into the realm of the symbolic.

Medication Prescribed Within One Year Preceding Fall-Related Injuries in Ontario Older Adults

Background

Serious injuries secondary to falls are becoming more prevalent due to the worldwide ageing of societies. Several medication classes have been associated with falls and fall-related injuries. The purpose of this study was to describe medication classes and the number of medication classes prescribed to older adults prior to the fall-related injury.

Methods

This population-based descriptive study used secondary administrative health-care data in Ontario, Canada for 2010-2014. Descriptive statistics were reported for Anatomic Therapeutic Chemical 4^th level medication classes. Frequency of medications prescribed to older adults was calculated on different sex, age groups, types of medications, and injures.

Results

Over five years (2010-2014), 288,251 older adults (63.2% females) were admitted to an emergency department for a fall-related injury (40.0% fractures, 12.1% brain injury). In the year before the injury, 48.5% were prescribed statins, 27.2% antidepressants, 25.0% opioids, and 16.6% anxiolytics. Females were prescribed more diuretics, antidepressants, and anxiolytics than males; and people aged 85 years and older had a higher percentage of diuretics, antidepressants, and antipsychotics. There were 36.4% of older adults prescribed 5-9 different medication classes and 41.2% were prescribed 10 or more medication classes.

Discussion

Older adults experiencing fall-related injuries were prescribed more opioids, benzodiazepines, and antidepressants than previously reported for the general population of older adults in Ontario. Higher percentage of females and more 85+ older adults were prescribed with psychotropic drugs, and they were also found to be at higher risk of fall-related injuries. Further associations between medications and fall-related injuries need to be explored in well-defined cohort studies.

What matters when it comes to measuring Age-Friendly Health System transformation

Thousands of health systems are now recognized as "Age-Friendly Health Systems," making this model one of the most widely disseminated - and most promising- models to redesign care delivery for older adults. Sustaining these gains will require demonstrating the impact on care delivery and outcomes of older adults. We propose a new measurement model to more tightly link Age-Friendly Health System transformation to outcomes within each "M" (What Matters, Medications, Mobility, and Mentation). We evaluated measures based on the following characteristics: (1) conceptual responsiveness to changes brought about by practicing "4Ms" care; (2) degree to which they represent outcomes that matter to older adults; and (3) how they can be feasibly, reliably, and validly measured. We offer specific examples of how novel measures are currently being used where available. Finally, we present measures that could capture system-level effects across "M"s. We tie these suggestions together into a conceptual measurement model for AFHS transformation, with the intent to spur discussion, debate, and iterative improvement in measures over time.

Update of the fracture risk prediction tool FRAX: a systematic review of potential cohorts and analysis plan

We describe the collection of cohorts together with the analysis plan for an update of the fracture risk prediction tool FRAX with respect to current and novel risk factors. The resource comprises 2,138,428 participants with a follow-up of approximately 20 million person-years and 116,117 documented incident major osteoporotic fractures.

INTRODUCTION

The availability of the fracture risk assessment tool FRAX® has substantially enhanced the targeting of treatment to those at high risk of fracture with FRAX now incorporated into more than 100 clinical osteoporosis guidelines worldwide. The aim of this study is to determine whether the current algorithms can be further optimised with respect to current and novel risk factors.

METHODS

A computerised literature search was performed in PubMed from inception until May 17, 2019, to identify eligible cohorts for updating the FRAX coefficients. Additionally, we searched the abstracts of conference proceedings of the American Society for Bone and Mineral Research, European Calcified Tissue Society and World Congress of Osteoporosis. Prospective cohort studies with data on baseline clinical risk factors and incident fractures were eligible.

RESULTS

Of the 836 records retrieved, 53 were selected for full-text assessment after screening on title and abstract. Twelve cohorts were deemed eligible and of these, 4 novel cohorts were identified. These cohorts, together with 60 previously identified cohorts, will provide the resource for constructing an updated version of FRAX comprising 2,138,428 participants with a follow-up of approximately 20 million person-years and 116,117 documented incident major osteoporotic fractures. For each known and candidate risk factor, multivariate hazard functions for hip fracture, major osteoporotic fracture and death will be tested using extended Poisson regression. Sex- and/or ethnicity-specific differences in the weights of the risk factors will be investigated. After meta-analyses of the cohort-specific beta coefficients for each risk factor, models comprising 10-year probability of hip and major osteoporotic fracture, with or without femoral neck bone mineral density, will be computed.

CONCLUSIONS

These assembled cohorts and described models will provide the framework for an updated FRAX tool enabling enhanced assessment of fracture risk (PROSPERO (CRD42021227266)).

Efficacy of a multiple-component and multifactorial personalized fall prevention program in a mixed population of community-dwelling older adults with stroke, Parkinson's Disease, or frailty compared to usual care: The PRE.C.I.S.A. randomized controlled trial

Background

Fall risk in the elderly is a major public health issue due to the injury-related consequences and the risk of associated long-term disability. However, delivering preventive interventions in usual clinical practice still represents a challenge.

Aim

To evaluate the efficacy of a multiple-component combined with a multifactorial personalized intervention in reducing fall rates in a mixed population of community-dwelling elderly compared to usual care.

Design

Randomized Controlled Trial (NCT03592420, clinicalTrials.gov).

Setting

Outpatients in two Italian centers.

Population

403 community-dwelling elderly at moderate-to-high fall risk, including subjects with Parkinson's Disease and stroke.

Methods

After the randomization, the described interventions were administered to the intervention group (n = 203). The control group (n = 200) received usual care and recommendations to minimize fall risk factors. In addition, each participant received a fall diary, followed by 12 monthly phone calls. The primary endpoint was the total number of falls in each group over 12 months, while the secondary endpoints were other fall-related indicators recorded at one year. In addition, participants' functioning was assessed at baseline (T1) and 3-month (T3).

Results

690 falls were reported at 12 months, 48.8% in the intervention and 51.2% in the control group, with 1.66 (± 3.5) and 1.77 (± 3.2) mean falls per subject, respectively. Subjects with ≥ 1 fall and ≥2 falls were, respectively, 236 (58.6%) and 148 (36.7%). No statistically significant differences were observed between groups regarding the number of falls, the falling probability, and the time to the first fall. According to the subgroup analysis, no significant differences were reported. However, a statistically significant difference was found for the Mini-BESTest (p = 0.004) and the Fullerton Advanced Balance Scale (p = 0.006) for the intervention group, with a small effect size (Cohen's d 0.26 and 0.32, respectively), at T1 and T3 evaluations.

Conclusions

The intervention was ineffective in reducing the number of falls, the falling probability, and the time to the first fall at 12 months in a mixed population of community-dwelling elderly. A significant improvement for two balance indicators was recorded in the intervention group. Future studies are needed to explore different effects of the proposed interventions to reduce falls and consequences.

Systematic review and critical methodological appraisal of community-based falls prevention economic models

BACKGROUND

Falls impose significant health and economic burdens on community-dwelling older persons. Decision modelling can inform commissioning of alternative falls prevention strategies. Several methodological challenges arise when modelling public health interventions including community-based falls prevention. This study aims to conduct a systematic review (SR) to: systematically identify community-based falls prevention economic models; synthesise and critically appraise how the models handled key methodological challenges associated with public health modelling; and suggest areas for further methodological research.

METHODS

The SR followed the 2021 PRISMA reporting guideline and covered the period 2003-2020 and 12 academic databases and grey literature. The extracted methodological features of included models were synthesised by their relevance to the following challenges: (1) capturing non-health outcomes and societal intervention costs; (2) considering heterogeneity and dynamic complexity; (3) considering theories of human behaviour and implementation; and (4) considering equity issues. The critical appraisal assessed the prevalence of each feature across models, then appraised the methods used to incorporate the feature. The methodological strengths and limitations stated by the modellers were used as indicators of desirable modelling practice and scope for improvement, respectively. The methods were also compared against those suggested in the broader empirical and methodological literature. Areas of further methodological research were suggested based on appraisal results.

RESULTS

46 models were identified. Comprehensive incorporation of non-health outcomes and societal intervention costs was infrequent. The assessments of heterogeneity and dynamic complexity were limited; subgroup delineation was confined primarily to demographics and binary disease/physical status. Few models incorporated heterogeneity in intervention implementation level, efficacy and cost. Few dynamic variables other than age and falls history were incorporated to characterise the trajectories of falls risk and general health/frailty. Intervention sustainability was frequently based on assumptions; few models estimated the economic/health returns from improved implementation. Seven models incorporated ethnicity- and severity-based subgroups but did not estimate the equity-efficiency trade-offs. Sixteen methodological research suggestions were made.

CONCLUSION

Existing community-based falls prevention models contain methodological limitations spanning four challenge areas relevant for public health modelling. There is scope for further methodological research to inform the development of falls prevention and other public health models.

Physical Activity and Fall Prevention in Geriatric Inpatients in an Acute Care Unit (AGIR Study): Protocol for a Usability Study

Background

Falls are one of the world’s top 10 risks associated with disability in people older than 60 years. They also represent more than two-thirds of adverse events in hospitals, mainly affecting patients older than 65 years. Physical activity is a central intervention in fall prevention for older people. Whatever the details of the prevention strategy that is adopted (ie, how a mono- or multifactorial intervention is evaluated, the category of person the intervention targets, and where it is used), it is important to ensure that the proposed intervention is feasible and usable for the patient and the health care team.

Objective

The primary objective is to study the usability of carrying out a physical activity intervention, including 3 types of exercises, in older patients hospitalized in a geriatric acute care unit and categorized according to 3 fall risk levels: low, moderate, and high. The secondary objectives are to determine the difficulty of the physical exercise for patients with different fall risk levels, to study the health care team’s perceptions of the intervention’s feasibility, and to study the benefits for patients.

Methods

This is an open-label, unicenter, nonrandomized, usability prospective clinical trial. The intervention tested is a daily physical activity program. It consists of 3 types of physical exercise: staying out of bed for at least 3 hours, performing balance exercises while standing for 2 minutes, and the Five Times Sit to Stand transfer exercise. These exercises are carried out under the supervision of the health care team. Fall risk in the patients is classified with the Brief Geriatric Assessment tool. The exercise program starts on the second day of hospitalization after inclusion in the study. Patient assessment continues until the last day of hospitalization or the 20th day of hospitalization, whichever is earlier. For each fall-risk group and each type of exercise, the intervention will be defined as usable if at least 80% of the participants complete 75% or more of the exercises (ie, the ratio between the number of days when the patient completes a type of exercise and the total number of hospitalization days). The perceived feasibility by the health care team is measured with 2 scales, measuring perceived difficulty and time spent with the patient. The intervention benefit is evaluated using the performance of the Five Times Sit to Stand test before and after the intervention.

Results

The first patient was recruited on March 16, 2015. The study enrolled 266 patients, including 75 with low fall risk, 105 with moderate risk, and 85 with high risk.

Conclusions

We have not yet analyzed the results, but our observations suggest that the usability of each type of exercise for a given patient will depend on their fall risk level.

PUP® (Patient Is Up) Smart Sock Technology Prevents Falls Among Hospital Patients With High Fall Risk in a Clinical Trial and Observational Study

Hospital inpatient falls, especially of older adult patients, can result in injury and death and generate high costs. A new technology, PUP^® (Patient Is Up) Smart Socks, combines sensors and geolocation in socks with a wireless platform. To determine whether these socks prevent falls of patients with high fall risk, we performed a clinical trial at one hospital, and an observational study at two other hospitals. In the clinical trial, patients spent 1,694 patient-days wearing the socks, reducing falls from 4 to 0 per 1,000 patient-days (p < 0.01). In the observational study, patients spent 2,286 patient-days wearing the socks, reducing falls from 4 to 1.3 per 1,000 patient-days (p < 0.05). The new technology resulted in a significant reduction in fall rates among patients with high fall risk and may greatly reduce inpatient fall-related injury and death and their associated costs.

Effects of vitamin D supplementation on the functional outcome in patients with osteoporotic vertebral compression fracture and vitamin D deficiency

BACKGROUND

In osteoporotic vertebral compression fractures, supplementation using vitamin D preparations and maintenance of blood vitamin D level within the normal range are necessary for proper fracture union, enhancement of muscle strength, and maintenance of body balance. The purpose of this study is to investigate the effects of vitamin D supplementation on blood vitamin D level, pain relief, union time, and functional outcome in patients with osteoporotic vertebral compression fracture and vitamin D deficiency.

METHODS

One hundred thirty patients who were deficient in blood vitamin D level and had osteoporotic vertebral compression fracture were divided into supplementation group and non-supplementation group. Initially, 3 months, 6 months, and 12 months after the injury, radiographs were taken to assess fracture union, and questionnaires were evaluated to evaluate the functional outcome and quality of life.

RESULTS

The mean age of the 130 patients (36 males and 94 females) was 74.75 ± 7.25 years. There were no statistically significant differences in initial severity of low back pain, functional outcome, and quality of life between the insufficient group and the deficient group (all p values were > 0.05). There was no significant time-by-group interaction between the supplementation group and the non-supplementation group (p = 0.194). In terms of SF-36 physical component score, there was no significant time-by-group interaction between the supplementation group and the non-supplementation group (p = 0.934).

CONCLUSIONS

Fracture union was achieved in all patients regardless of serum vitamin D level, and there were significant improvements in severity of low back pain, functional outcome, and quality of life over 12 months in patients with osteoporotic vertebral compression fracture. Short-term vitamin D supplementation of patients with osteoporotic vertebral compression fracture and deficiency of vitamin D did not result in significant differences in fracture union status, functional outcome, and quality of life between the supplementation groups and the non-supplementation groups of patients.

Examining the Relationship Between Environmental Factors and Inpatient Hospital Falls: Protocol for a Mixed Methods Study

BACKGROUND

Patient falls are the most common adverse events reported in hospitals. Although it is well understood that the physical hospital environment contributes to nearly 40% of severe or fatal hospital falls, there are significant gaps in the knowledge about the relationship between inpatient unit design and fall rates. The few studies that have examined unit design have been conducted in a single hospital (non-Veterans Health Administration [VHA]) or a small number of inpatient units, limiting generalizability. The goal of this study is to identify unit design factors contributing to inpatient falls in the VHA.

OBJECTIVE

The first aim of the study is to investigate frontline and management perceptions of and experiences with veteran falls as they pertain to inpatient environmental factors. An iterative rapid assessment process will be used to analyze the data. Interview findings will directly inform the development of an environmental assessment survey to be conducted as part of aim 2 and to contribute to interpretation of aim 2. The second aim of this study is to quantify unit design factors and compare spatial and environmental factors of units with higher- versus lower-than-expected fall rates.

METHODS

We will first conduct walk-through interviews with facility personnel in 10 medical/surgical units at 3 VHA medical centers to identify environmental fall risk factors. Data will be used to finalize an environmental assessment survey for nurse managers and facilities managers. We will then use fall data from the VA Inpatient Evaluation Center and patient data from additional sources to identify 50 medical/surgical nursing units with higher- and lower-than-expected fall rates. We will measure spatial factors by analyzing computer-aided design files of unit floorplans and environmental factors from the environmental assessment survey. Statistical tests will be performed to identify design factors that distinguish high and low outliers.

RESULTS

The VA Health Services Research and Development Service approved funding for the study. The research protocol was approved by institutional review boards and VA research committees at both sites. Data collection started in February 2018. Results of the data analysis are expected by February 2022. Data collection and analysis was completed for aim 1 with a manuscript of results in progress. For aim 2, the medical/surgical units were categorized into higher- and lower-than-expected fall categories, the environmental assessment surveys were distributed to facility managers and nurse managers. Data to measure spatial characteristics are being compiled.

CONCLUSIONS

To our knowledge, this study is the first to objectively identify spatial risks for falls in hospitals within in a large multihospital system. Findings can contribute to evidence-based design guidelines for hospitals such as those of the Facility Guidelines Institute and the Department of Veterans Affairs. The metrics for characterizing spatial features are quantitative indices that could be incorporated in larger scale contextual studies examining contributors to falls, which to date often exclude physical environmental factors at the unit level. Space syntax measures could be used as physical environmental factors in future research examining a range of contextual factors-social, personal, organizational, and environmental-that contribute to patient falls.

Impact of Fall Risk and Direct Oral Anticoagulant Treatment on Quality-Adjusted Life-Years in Older Adults with Atrial Fibrillation: A Markov Decision Analysis

BACKGROUND AND OBJECTIVE

The decision to initiate anticoagulation in older adults with atrial fibrillation is complicated by the benefit of ischemic stroke prevention vs the risk of falls resulting in major bleeds. The objective of this study was to assess the impact of different treatments including direct oral anticoagulants on quality-adjusted life-years (QALYs) in patients aged 75 years and older with atrial fibrillation in the context of falls.

METHODS

A Markov decision process was constructed for older patients with atrial fibrillation taking no anti-thrombotic, aspirin, warfarin, rivaroxaban, and apixaban. Input probabilities for clinical events were estimated from the available literature. One-way and two-way sensitivity analyses were performed by measuring the impact of varying input probabilities of clinical events on QALY outcomes.

RESULTS

The base-case scenario estimated that older adults treated with no anti-thrombotic, aspirin, warfarin, rivaroxaban, and apixaban had QALYs of 8.03, 8.69, 10.38, 11.02, and 11.56, respectively. The sensitivity analysis estimated that an older adult would need to fall over 45 (rivaroxaban) and 458 (apixaban) times per year for the QALY of a direct oral anticoagulant to be lower than that of aspirin.

CONCLUSIONS

Older adults with atrial fibrillation benefit from stroke protection of anticoagulants, especially direct oral anticoagulants, even if they are at high risk of falls. Clinicians should not consider fall risk as a deciding factor for withholding anticoagulation in this population of patients.

Chronoprevention in hospital falls of older people: protocol for a mixed-method study

BACKGROUND

Accidental falls in hospitals are serious events concerning the safety of the patients. Recent studies demonstrated that the time of falls is a key factor to be considered in prevention. It has been shown that the time of day, the day of the week and the month of the year impact on the occurrence of falls. The aim of the study is to determine the effect of the application of a programme of preventive measures based on the temporal patterns of the risk factors on the hospital fall occurrence.

METHODS

A mixed-method research design. The following three phases will be carried out: 1) Longitudinal prospective study in two parts: (a) audits and seminars of healthcare professionals focused on an effective and efficient hospital falls register. Multi-Component and Single Cosinor analyses will be performed to obtain the temporal patterns of hospital falls and their related variables and (b) implementation of a based-temporal patterns, multidimensional prevention programme. 2) Retrospective study of falls registered in institutional databases. 3) Qualitative study based on focus groups (physicians, nurses and nursing assistants). The study protocol was approved in 2018.

DISCUSSION

With regard to the safety of patients, hospital falls are serious events. Recent studies have demonstrated that the time of falls is a key factor to be considered in prevention. It has been shown that the time of day, the day of the week and the month of the year impact on the occurrence of falls. It is imperative to study temporal patterns of hospital falls to effectively and comprehensively define the aetiology of falls and, therefore, design preventive strategies. A reduction of the number of in-hospital falls and related injuries is expected, as well as an improvement in the quality of life of patients. Considering temporal patterns and levels of mood and sleep of healthcare professionals will achieve an improvement in patient safety.

Older Adults' Perceived Barriers to Participation in a Falls Prevention Strategy

There is a need to increase older adults’ access and adherence to falls prevention strategies. This study aims to explore older adults’ perceived barriers to participation in a fall prevention strategy. A qualitative descriptive approach was used. Semi-structured interviews were conducted with 18 older adult users of a Day Care Unit from a Private Institution of Social Solidarity in the region of Lisbon and Tagus Valley in Portugal. The recruitment was made in September 2019. The interviews were recorded transcribed verbatim and analysed thematically using the method of constant comparisons. The barriers to participation in a fall prevention strategy are healthcare system gaps, social context, economic context, health status, psychological capability, and lack of knowledge to demystify myths and misconceptions about falls. There are different barriers to participate in a fall prevention strategy. It is urgent to eliminate or reduce the effect of these barriers to increase older adults’ participation in fall prevention strategies.

Management of glucocorticoid-induced osteoporosis

Long-term glucocorticoid (GC) therapy is frequently indicated to treat autoimmune and chronic inflammatory diseases in daily clinical practice. Two of the most devastating untoward effects are bone loss and fractures. Doses as low as 2.5 mg of prednisone for more than 3 months can impair bone integrity. Population at risk is defined based on the dose and duration of GC therapy and should be stratified according to FRAX (Fracture Risk Assessment Tool), major osteoporotic fracture, prior fractures, and bone mineral density values (BMD). General measures include to prescribe the lowest dose of GC to control the underlying disease for the shortest possible time, maintain adequate vitamin D levels and calcium intake, maintain mobility, and prescribe a bone acting agent in patients at high risk of fracture. These agents include oral and intravenous bisphosphonates, denosumab, and teriparatide.

Mismatch: a comparative study of vitamin D status in British-Bangladeshi migrants

Background and objectives

Low levels of vitamin D among dark-skinned migrants to northern latitudes and increased risks for associated pathologies illustrate an evolutionary mismatch between an environment of high ultraviolet (UV) radiation to which such migrants are adapted and the low UV environment to which they migrate. Recently, low levels of vitamin D have also been associated with higher risks for contracting COVID-19. South Asians in the UK have higher risk for low vitamin D levels. In this study, we assessed vitamin D status of British-Bangladeshi migrants compared with white British residents and Bangladeshis still living in Bangladesh (‘sedentees’).

Methodology

The cross-sectional study compared serum vitamin D levels among 149 women aged 35–59, comprising British-Bangladeshi migrants (n = 50), white British neighbors (n = 54) and Bangladeshi sedentees (n = 45). Analyses comprised multivariate models to assess serum levels of 25-hydroxyvitamin D (25(OH)D), and associations with anthropometric, lifestyle, health and migration factors.

Results

Vitamin D levels in Bangladeshi migrants were very low: mean 25(OH)D = 32.2 nmol/L ± 13.0, with 29% of migrants classified as deficient (<25 nmol/L) and 94% deficient or insufficient (≤50 nmol/L). Mean levels of vitamin D were significantly lower among British-Bangladeshis compared with Bangladeshi sedentees (50.9 nmol/L ± 13.3, P < 0.001) and were also lower than in white British women (55.3 nmol/L ± 20.9). Lower levels of vitamin D were associated with increased body mass index and low iron status.

Conclusions and implications

We conclude that lower exposure to sunlight in the UK reduces vitamin D levels in Bangladeshi migrants. Recommending supplements could prevent potentially adverse health outcomes associated with vitamin D deficiency.

Lay Summary

Vitamin D deficiency is one example of mismatch between an evolved trait and novel environments. Here we compare vitamin D status of dark-skinned British-Bangladeshi migrants in the UK to Bangladeshis in Bangladesh and white British individuals. Migrants had lower levels of vitamin D and are at risk for associated pathologies.

Patterns of Sedentary Behavior among Older Adults in Care Facilities: A Scoping Review

Understanding the sedentary patterns can guide the design of strategies to engage older adults in physical activity. This scoping review aimed to synthesize available evidence on sedentary behaviors in care facilities. We searched PubMed/MEDLINE and Web of Science for studies published from inception through October 2020. Eighteen studies were included and reviewed according to the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) guidelines. Data obtained were analyzed based on levels of care provided. Overall, daily sedentary time was higher among residents in high level care facilities (e.g., nursing homes) (11.6 h/day) than intermediate/mixed level care facilities (e.g., assisted living) (9.5 h/day). In intermediate/mixed level care facilities, television (TV) viewing was the most common sedentary activity (2.5-2.9 h/day; 26% of daily sedentary time), while napping was the most favorite sedentary activity (4.7 h/day; 36% of waking hours) in high level care facilities. Sex differences in daily patterns of sedentary behavior (sedentary time, uninterrupted bouts, and bout durations) were commonly observed in intermediate/mixed level care facilities, as exemplified by men being more sedentary by 0.7-1.1 h/day. In summary, this study highlights distinctive sedentary patterns among older adults residing in different levels of care facilities, addressing a pressing need for customized interventions to engage care facility residents in physical activity.

Treatment effects in randomised trials using routinely collected data for outcome assessment versus traditional trials: meta-research study

OBJECTIVE

To compare effect estimates of randomised clinical trials that use routinely collected data (RCD-RCT) for outcome ascertainment with traditional trials not using routinely collected data.

DESIGN

Meta-research study.

DATA SOURCE

Studies included in the same meta-analysis in a Cochrane review.

ELIGIBILITY CRITERIA FOR STUDY SELECTION

Randomised clinical trials using any type of routinely collected data for outcome ascertainment, including from registries, electronic health records, and administrative databases, that were included in a meta-analysis of a Cochrane review on any clinical question and any health outcome together with traditional trials not using routinely collected data for outcome measurement.

REVIEW METHODS

Effect estimates from trials using or not using routinely collected data were summarised in random effects meta-analyses. Agreement of (summary) treatment effect estimates from trials using routinely collected data and those not using such data was expressed as the ratio of odds ratios. Subgroup analyses explored effects in trials based on different types of routinely collected data. Two investigators independently assessed the quality of each data source.

RESULTS

84 RCD-RCTs and 463 traditional trials on 22 clinical questions were included. Trials using routinely collected data for outcome ascertainment showed 20% less favourable treatment effect estimates than traditional trials (ratio of odds ratios 0.80, 95% confidence interval 0.70 to 0.91, I2=14%). Results were similar across various types of outcomes (mortality outcomes: 0.92, 0.74 to 1.15, I2=12%; non-mortality outcomes: 0.71, 0.60 to 0.84, I2=8%), data sources (electronic health records: 0.81, 0.59 to 1.11, I2=28%; registries: 0.86, 0.75 to 0.99, I2=20%; administrative data: 0.84, 0.72 to 0.99, I2=0%), and data quality (high data quality: 0.82, 0.72 to 0.93, I2=0%).

CONCLUSIONS

Randomised clinical trials using routinely collected data for outcome ascertainment show smaller treatment benefits than traditional trials not using routinely collected data. These differences could have implications for healthcare decision making and the application of real world evidence.

Is it reasonable to ignore vitamin D status for musculoskeletal health?

Severe vitamin D deficiency—25-hydroxyvitamin D (25OHD) concentrations below around 25–30 nmol/L—may lead to growth plate disorganization and mineralization abnormalities in children (rickets) and mineralization defects throughout the skeleton (osteomalacia) and proximal muscle weakness. Both problems are reversed with vitamin D treatment. Apart from this musculoskeletal dysfunction at very low vitamin D levels, there is apparent inconsistency in the available data about whether concentrations of 25OHD below around 50 nmol/L cause muscle function impairment and increase the risk of fracture. This narrative review provides evidence to support the contention that improving vitamin D status, up to around 50 nmol/L, plays a small causal role in optimizing bone and muscle function as well as reducing overall mortality.

Fall prevention implementation strategies in use at 60 United States hospitals: a descriptive study

BACKGROUND

To guide fall prevention efforts, United States organisations, such as the Joint Commission and the Agency for Healthcare Research and Quality, have recommended organisational-level implementation strategies: leadership support, interdisciplinary falls committees, electronic health record tools, and staff, family and patient education. It is unclear whether hospitals adhere to such strategies or how these strategies are operationalised.

OBJECTIVE

To identify and describe the prevalence of specific hospital fall prevention implementation strategies.

METHODS

In 2017, we surveyed 80 US hospitals participating in the National Database of Nursing Quality Indicators who volunteered for the study. We conducted descriptive statistics by calculating percentages for categorical variables and the median and IQR for count variables.

RESULTS

A total of 60/80 (75%) of hospitals completed the survey. The majority of hospitals were not-for-profit (98%) and urban (90%); more than half were Magnet (53%), small (53%) and teaching (52%). Hospitals were more likely to use leadership strategies, such as updating fall policies in the past 3 years (98%) but less likely to reward staff (40%). Hospitals commonly used interdisciplinary falls committees (83%) but membership rarely included physicians. Hospitals lacked access to electronic health record tools, such as high-risk medication warnings (27%). Education strategies were commonly used; 100% of hospitals provided fall education at staff orientation, but only 22% educated all employees (not just nursing staff).

CONCLUSIONS

Our study is the first to our knowledge to examine which expert-recommended implementation strategies are being used and how they are being operationalised in US hospitals. Future studies are needed to document fall prevention implementation strategies in detail and to test which implementation strategies are most effective at reducing falls. Additionally, research is needed to evaluate the quality of implementation (eg, fidelity) of fall prevention interventions.

Evaluation of a Patient-Centered Fall-Prevention Tool Kit to Reduce Falls and Injuries: A Nonrandomized Controlled Trial

IMPORTANCE

Falls represent a leading cause of preventable injury in hospitals and a frequently reported serious adverse event. Hospitalization is associated with an increased risk for falls and serious injuries including hip fractures, subdural hematomas, or even death. Multifactorial strategies have been shown to reduce falls in acute care hospitals, but evidence for fall-related injury prevention in hospitals is lacking.

OBJECTIVE

To assess whether a fall-prevention tool kit that engages patients and families in the fall-prevention process throughout hospitalization is associated with reduced falls and injurious falls.

DESIGN, SETTING, AND PARTICIPANTS

This nonrandomized controlled trial using stepped wedge design was conducted between November 1, 2015, and October 31, 2018, in 14 medical units within 3 academic medical centers in Boston and New York City. All adult inpatients hospitalized in participating units were included in the analysis.

INTERVENTIONS

A nurse-led fall-prevention tool kit linking evidence-based preventive interventions to patient-specific fall risk factors and designed to integrate continuous patient and family engagement in the fall-prevention process.

MAIN OUTCOMES AND MEASURES

The primary outcome was the rate of patient falls per 1000 patient-days in targeted units during the study period. The secondary outcome was the rate of falls with injury per 1000 patient-days.

RESULTS

During the interrupted time series, 37 231 patients were evaluated, including 17 948 before the intervention (mean [SD] age, 60.56 [18.30] years; 9723 [54.17%] women) and 19 283 after the intervention (mean [SD] age, 60.92 [18.10] years; 10 325 [53.54%] women). There was an overall adjusted 15% reduction in falls after implementation of the fall-prevention tool kit compared with before implementation (2.92 vs 2.49 falls per 1000 patient-days [95% CI, 2.06-3.00 falls per 1000 patient-days]; adjusted rate ratio 0.85; 95% CI, 0.75-0.96; P = .01) and an adjusted 34% reduction in injurious falls (0.73 vs 0.48 injurious falls per 1000 patient-days [95% CI, 0.34-0.70 injurious falls per 1000 patient-days]; adjusted rate ratio, 0.66; 95% CI, 0.53-0.88; P = .003).

CONCLUSIONS AND RELEVANCE

In this nonrandomized controlled trial, implementation of a fall-prevention tool kit was associated with a significant reduction in falls and related injuries. A patient-care team partnership appears to be beneficial for prevention of falls and fall-related injuries.

Increasing the uptake of vitamin D supplement use in Australian residential aged care facilities: results from the vitamin D implementation (ViDAus) study

BACKGROUND

Adequate (≥800 IU/day) vitamin D supplement use in Australian residential aged care facilities (RACFs) is variable and non-optimal. The vitamin D implementation (ViDAus) study aimed to employ a range of strategies to support the uptake of this best practice in participating facilities. The aim of this paper is to report on facility level prevalence outcomes and factors associated with vitamin D supplement use.

METHODS

This trial followed a stepped wedge cluster, non-randomised design with 41 individual facilities serving as clusters pragmatically allocated into two wedges that commenced the intervention six months apart. This multifaceted, interdisciplinary knowledge translation intervention was led by a project officer, who worked with nominated champions at participating facilities to provide education and undertake quality improvement (QI) planning. Local barriers and responsive strategies were identified to engage stakeholders and promote widespread uptake of vitamin D supplement use.

RESULTS

This study found no significant difference in the change of vitamin D supplement use between the intervention (17 facilities with approx. 1500 residents) and control group (24 facilities with approx. 1900 residents) at six months (difference in prevalence change between groups was 1.10, 95% CI - 3.8 to 6.0, p = 0.6). The average overall facility change in adequate (≥800 IU/day) vitamin D supplement use over 12 months was 3.86% (95% CI 0.6 to 7.2, p = 0.02), which achieved a facility level average prevalence of 59.6%. The variation in uptake at 12 months ranged from 25 to 88% of residents at each facility. In terms of the types of strategies employed for implementation, there were no statistical differences between facilities that achieved a clinically meaningful improvement (≥10%) or a desired prevalence of vitamin D supplement use (80% of residents) compared to those that did not.

CONCLUSIONS

This work confirms the complex nature of implementation of best practice in the RACF setting and indicates that more needs to be done to ensure best practice is translated into action. Whilst some strategies appeared to be associated with better outcomes, the statistical insignificance of these findings and the overall limited impact of the intervention suggests that the role of broader organisational and governmental support for implementation should be investigated further.

Analysis of Fall Risk Factors in an Aging Population Living in Long-Term Care Institutions in SPAIN: A Retrospective Cohort Study

Falls in the elderly are associated with morbidity and mortality. Research about fall risk factors in Spanish care facilities is scarce. This study aimed to assess the prevalence of falls among residents living in long-term care Spanish institutions and to identify fall risk factors in this population. A nationwide retrospective cohort study was conducted in 113 centers. Persons over 70 years old who were living in a residential setting for at least 1 year were included. Simple and multiple regression analyses were conducted to estimate the associations between the main clinical variables registered in the databases and the presence of falls. A total of 2849 subjects were analyzed (mean age 85.21 years). The period prevalence of fallers in the last 12 months was 45.3%, with a proportion of recurrent fallers of 51.7%. The presence of falls was associated with lower Tinetti Scale scores (OR = 1.597, 95% CI: 1.280, 1.991; OR = 1.362, 95% CI: 1.134, 1.635), severe or moderate cognitive impairment (OR= 1.992, 95% CI: 1.472, 2.695; OR = 1.507, 95% CI: 1.231, 1.845, respectively), and polypharmacy (OR = 1.291, 95% CI: 1.039, 1.604). Fall prevention interventions should focus on the prevention of balance and cognitive deterioration and the improvement of these functions when possible. It should also focus on a periodical medication history revision aiming to avoid inappropriate prescriptions.

Feasibility of Motivational Interviewing to Engage Older Inpatients in Fall Prevention: A Pilot Randomized Controlled Trial

In the current 3-month, two arm, unblinded, single site, pilot randomized controlled trial, 120 high fall risk hospitalized older adults (age ≥65) were contacted, and 67 participants were enrolled. The intervention arm received a brief motivational interviewing (MI) intervention. Both arms received routine hospital fall prevention protocols. Measurements were conducted at baseline, 2 days, 1 week, 1 month, and 3 months. MI intervention took approximately 21 minutes and was provided at beginning proficiency level. Approximately 66% of participants completed 3-month data collection. The intervention group reported a greater decrease in fear of falling after the intervention than the control arm (β = -0.856 vs. β = -0.236) and maintained fall prevention behaviors at 3 months (β = 0.001 vs. β = -0.083) (p < 0.05). The current study found brief MI for fall prevention in acute settings feasible and provided preliminary evidence for a positive impact of MI [Journal of Gerontological Nursing, 45(9), 19-29.].

Health, Functional and Nutritional Determinants of Falls Experienced in the Previous Year-A Cross-Sectional Study in a Geriatric Ward

Falls are a serious health problem in older adults. A limited number of studies assessed their multifactorial nature in geriatric ward patients. The aim of this study is to explore health, functional and nutritional correlates of experiencing fall(s) in the previous year by older inpatients. A cross-sectional study of patients admitted to the department of geriatrics was conducted. A "faller status" was defined based on positive history of falls in the previous 12 months. Health, functional and nutritional factors associated with falls were evaluated, and multivariable logistic regression analysis models were built. A total of 358 patients (median age 82 (IQR 76-86) years, 77.9% women) were recruited, 43.9% of whom reported falls. The "fallers" presented with a significantly higher number of chronic diseases, higher prevalence of Parkinson's disease, peripheral arterial disease, chronic osteoarthritis, more frequently reported urinary incontinence and were dependent on others for daily living activities. They had significantly worse results for the assessment of gait, balance and frailty status. The Mini Nutritional Assessment-Short Form scores and the mean value of serum albumin were significantly lower in the fallers' group. Parkinson's disease (OR = 2.82, CI-1.07-7.45; p = 0.04) and osteoarthritis (OR = 2.08, CI-1.02-4.23; p = 0.04) were the main variables for the outcome prediction, according to the direct multivariable logistic regression analysis. Our findings suggest that Parkinson's disease and osteoarthritis are the main predictors independently associated with a history of falls in patients admitted to the geriatric ward, although the influence of some factors may be underestimated due to the tendency of not taking the history of falls in very frail, functionally dependent and bedridden individuals.

Impact of the backward chaining method on physical and psychological outcome measures in older adults at risk of falling: a systematic review

BACKGROUND

Being unable to "get up from the floor" is a risk factor and predictor of serious fall-related injuries in older age; however, floor-rise training (FRT) is not widely used. The backward chaining method (BCM) is a success-oriented, step-by-step form of FRT. This systematic review aimed to evaluate the impact of BCM on physical and psychological outcome measures, and its clinical application.

METHODS

Studies were identified through systematic searching of five databases. Criteria for inclusion were: use of BCM as a treatment method, outcome measures related to falls, and participants aged 60 + years. Study quality was evaluated using the Mixed Methods Appraisal Tool and PEDro scale, if applicable.

RESULTS

Seven studies with a total of 446 participants (mean age 82.4 ± 5.3 years) were identified. Emerging evidence shows that BCM significantly improves the ability to get up unassisted from the floor, as well as mobility with reduced fall incidence in older people. Furthermore, it can potentially reduce fear of falling. Reporting on feasibility and acceptance of BCM was limited. Study quality varied widely.

CONCLUSIONS

BCM provides a promising intervention in fall-related recovery strategies for older adults and is most effective when offered to older adults at risk of falling. Considering the small number of included studies and the varying methodological quality, these findings should be evaluated accordingly. The growing evidence regarding the benefits of BCM, yet the lack of adoption into standard care, highlights the need for further research and clinical application of this intervention approach.

Predicting Inpatient Falls Using Natural Language Processing of Nursing Records Obtained From Japanese Electronic Medical Records: Case-Control Study

BACKGROUND

Falls in hospitals are the most common risk factor that affects the safety of inpatients and can result in severe harm. Therefore, preventing falls is one of the most important areas of risk management for health care organizations. However, existing methods for predicting falls are laborious and costly.

OBJECTIVE

The objective of this study is to verify whether hospital inpatient falls can be predicted through the analysis of a single input-unstructured nursing records obtained from Japanese electronic medical records (EMRs)-using a natural language processing (NLP) algorithm and machine learning.

METHODS

The nursing records of 335 fallers and 408 nonfallers for a 12-month period were extracted from the EMRs of an acute care hospital and randomly divided into a learning data set and test data set. The former data set was subjected to NLP and machine learning to extract morphemes that contributed to separating fallers from nonfallers to construct a model for predicting falls. Then, the latter data set was used to determine the predictive value of the model using receiver operating characteristic (ROC) analysis.

RESULTS

The prediction of falls using the test data set showed high accuracy, with an area under the ROC curve, sensitivity, specificity, and odds ratio of mean 0.834 (SD 0.005), mean 0.769 (SD 0.013), mean 0.785 (SD 0.020), and mean 12.27 (SD 1.11) for five independent experiments, respectively. The morphemes incorporated into the final model included many words closely related to known risk factors for falls, such as the use of psychotropic drugs, state of consciousness, and mobility, thereby demonstrating that an NLP algorithm combined with machine learning can effectively extract risk factors for falls from nursing records.

CONCLUSIONS

We successfully established that falls among hospital inpatients can be predicted by analyzing nursing records using an NLP algorithm and machine learning. Therefore, it may be possible to develop a fall risk monitoring system that analyzes nursing records daily and alerts health care professionals when the fall risk of an inpatient is increased.

Vitamin D: Newer Concepts of Its Metabolism and Function at the Basic and Clinical Level

The interest in vitamin D continues unabated with thousands of publications contributing to a vast and growing literature each year. It is widely recognized that the vitamin D receptor (VDR) and the enzymes that metabolize vitamin D are found in many cells, not just those involved with calcium and phosphate homeostasis. In this mini review I have focused primarily on recent studies that provide new insights into vitamin D metabolism, mechanisms of action, and clinical applications. In particular, I examine how mutations in vitamin D metabolizing enzymes-and new information on their regulation-links vitamin D metabolism into areas such as metabolism and diseases outside that of the musculoskeletal system. New information regarding the mechanisms governing the function of the VDR elucidates how this molecule can be so multifunctional in a cell-specific fashion. Clinically, the difficulty in determining vitamin D sufficiency for all groups is addressed, including a discussion of whether the standard measure of vitamin D sufficiency, total 25OHD (25 hydroxyvitamin) levels, may not be the best measure-at least by itself. Finally, several recent large clinical trials exploring the role of vitamin D supplementation in nonskeletal diseases are briefly reviewed, with an eye toward what questions they answered and what new questions they raised.

Educating health professionals to optimise falls screening in hospitals: protocol for a mixed methods study

BACKGROUND

Falls in hospitals remain a major challenge to patient safety. All hospitalised adults are at risk of falling during their inpatient stay, though this risk is not always realised by patients and clinicians. This study will evaluate the outcomes of a hospital clinician education program that teaches clinicians how to screen for falls risk and assign mitigation strategies using clinical reasoning, rather than relying on a standardised falls risk assessment tool (FRAT). The education program aims to increase clinician knowledge, motivation and confidence in screening falls risk and selecting individual falls prevention interventions. Perceptions of the education intervention will also be examined.

METHODS

Participants will be a sample of convenience of nurses and allied health professionals from five Australian hospitals. For each hospital there will be two cohorts. Cohort 1 will be clinical leaders who shall receive a three-hour education program on the latest evidence in hospital falls risk assessment and how to implement a new falls screening and management tool. They will also be taught practical skills to enable them to deliver an effective one-hour in-service training session to Cohort 2. Cohort 2 will be recruited from the workforce as a whole and include nurses and other health professionals involved in routine hospital falls screening and prevention. The investigation will be framed on Keller's Model of Motivational Design and Kirkpatrick's evaluation framework. It will involve a mixed methods pre and post-test questionnaire design inclusive of semi-structured telephone interviews, to triangulate the data from multiple approaches.

DISCUSSION

This study will quantify the outcomes of a high-quality clinician education program to increase knowledge of evidence-based practice for falls prevention. It is predicted that positive behavioural changes will occur in health professionals, leading to organisational change and improved patient outcomes. Furthermore, the findings from the study will inform the future refinement of educational delivery to health professionals across hospital sites.

TRIAL REGISTRATION

The study has also been approved by the Australian New Zealand Clinical Trials Registry: Preventing Hospital Falls: Optimal Screening UTN U1111-1225-8450. Universal Trial Number (UTN): U1111-1228-0041 (obtained 5/2/19). Australian New Zealand Clinical Trials Registry (ANZCTR): ACTRN12619000200189 (obtained 12/2/19).

Frailty and Comprehensive Geriatric Assessment

Frailty is defined as a reduced physiologic reserve vulnerable to external stressors. For older individuals, frailty plays a decisive role in increasing adverse health outcomes in most clinical situations. Many tools or criteria have been introduced to define frailty in recent years, and the definition of frailty has gradually converged into several consensuses. Frail older adults often have multi-domain risk factors in terms of physical, psychological, and social health. Comprehensive geriatric assessment (CGA) is the process of identifying and quantifying frailty by examining various risky domains and body functions, which is the basis for geriatric medicine and research. CGA provides physicians with information on the reversible area of frailty and the leading cause of deterioration in frail older adults. Therefore frailty assessment based on understanding CGA and its relationship with frailty, can help establish treatment strategies and intervention in frail older adults. This review article summarizes the recent consensus and evidence of frailty and CGA.

A population-based study of 2347 fall-related injuries among older people in a Finnish emergency department

PURPOSE

Fall-related injuries are a significant cause of morbidity, mortality and functional decline among older people. The aim of this study is to analyze the incidence of fall-related emergency department (ED) visits and compare the characteristics of single and recurrent fallers in a population-based sample.

METHODS

Consecutive patients aged ≥ 80 years and living in the Tampere city region who visited collaborative emergency department within a two-year study period (1 January 2015 to 31 December 2016) due to fall-related injury were included. The incidence of fall-related injuries and recurrent falls was calculated using population statistics.

RESULTS

A total of 6915 ≥ 80-year-old patients visited our ED 17,769 times during the study period. Thirteen percent of these visits (n = 2347, median 87 years, 80-103 years; 74% female) were fall-related. The incidence of fall-related ED visits increased from 94/1000 person-years to 171/1000 among those aged 80-89 years and ≥ 90 years, respectively. Twenty-four percent of patients had recurrent falls (range 2-5) during the observational period. Twenty-five percent of those discharged home had a subsequent fall-related injury within one month after the index visit. The distribution of diagnoses was similar among those with single and recurrent falls.

CONCLUSION

Fall-related injuries are a significant health issue. Almost one in eight of all ED visits were fall-related, and 24% of patients had recurrent fall-related injuries. The risk of subsequent injury was high during the first month after the first injury, emphasizing the need to intervene with the fall risk promptly.

A multicomponent exercise intervention to improve physical functioning, cognition and psychosocial well-being in elderly nursing home residents: a study protocol of a randomized controlled trial in the PROCARE (prevention and occupational health in long-term care) project

BACKGROUND

Older adults, who are living in nursing homes that provide a high level of long-term nursing care, are characterized by multimorbidity and a high prevalence of dependency in activities of daily living. Results of recent studies indicate positive effects of structured exercise programs during long-term care for physical functioning, cognition, and psychosocial well-being. However, for frail elderly the evidence remains inconsistent. There are no evidence-based guidelines for exercises for nursing home residents that consider their individual deficits and capacities. Therefore, high-quality studies are required to examine the efficacy of exercise interventions for this multimorbid target group. The purpose of this study is to determine the feasibility and efficacy of a multicomponent exercise intervention for nursing home residents that aims to improve physical and cognitive functioning as well as quality of life.

METHODS

A two-arm single-blinded multicenter randomized controlled trial will be conducted, including 48 nursing homes in eight regions of Germany with an estimated sample size of 1120 individuals. Participants will be randomly assigned to either a training or a waiting time control group. For a period of 16 weeks the training group will meet twice a week for group-based sessions (45-60 min each), which will contain exercises to improve physical functioning (strength, endurance, balance, flexibility) and cognitive-motor skills (dual-task). The intervention is organized as a progressive challenge which is successively adapted to the residents' capacities. Physical functioning, cognitive performance, and quality of life will be assessed in both study groups at baseline (pre-test), after 16-weeks (post-treatment), and after 32-weeks (retention test, intervention group only).

DISCUSSION

This study will provide information about the efficacy of a multicomponent exercise program in nursing homes (performance, recruitment). Results from this trial will contribute to the evidence of multicomponent exercises, which specifically focus on cognitive-motor approaches in the maintenance of mental and physical functioning. In addition, it will help to encourage older adults to actively engage in social life. Furthermore, the findings will lead to recommendations for health promotion interventions for frail nursing home residents.

Interventions for preventing falls in people with multiple sclerosis

BACKGROUND

Multiple sclerosis (MS) is one of the most prevalent diseases of the central nervous system with recent prevalence estimates indicating that MS directly affects 2.3 million people worldwide. Fall rates of 56% have been reported among people with MS in a recent meta-analysis. Clinical guidelines do not outline an evidence-based approach to falls interventions in MS. There is a need for synthesised information regarding the effectiveness of falls prevention interventions in MS.

OBJECTIVES

The aim of this review was to evaluate the effectiveness of interventions designed to reduce falls in people with MS. Specific objectives included comparing: (1) falls prevention interventions to controls and; (2) different types of falls prevention interventions.

SEARCH METHODS

We searched the Trials Register of the Cochrane Multiple Sclerosis and Rare Diseases of the CNS Group, Cochrane Central Register of Controlled Trials (2018 Issue 9); MEDLINE (PubMed) (1966 to 12 September 2018); Embase (EMBASE.com) (1974 to 12 September 2018); Cumulative Index to Nursing and Allied Health Literature (EBSCOhost) (1981 to 12 September 2018); Latin American and Caribbean Health Science Information Database (Bireme) (1982 to 12 September 2018); ClinicalTrials.gov; and World Health Organization International Clinical Trials Registry Platform; PsycINFO (1806 to 12 September 2018; and Physiotherapy Evidence Database (1999 to 12 September 2018).

SELECTION CRITERIA

We selected randomised controlled trials or quasi-randomised trials of interventions to reduce falls in people with MS. We included trials that examined falls prevention interventions compared to controls or different types of falls prevention interventions. Primary outcomes included: falls rate, risk of falling, number of falls per person and adverse events.

DATA COLLECTION AND ANALYSIS

Two review authors screened studies for selection, assessed risk of bias and extracted data. We used a rate ratio (RaR) and 95% confidence interval to compare falls rate between groups. For risk of falling, we used a risk ratio (RR) and 95% CI based on the number of fallers in each group.

MAIN RESULTS

A total of 839 people with MS (12 to 177 individuals) were randomised in the 13 included trials. The mean age of the participants was 52 years (36 to 62 years). The percentage of women participants ranged from 59% to 85%. Studies included people with all types of MS. Most trials compared an exercise intervention with no intervention or different types of falls prevention interventions. We included two comparisons: (1) Falls prevention intervention versus control and (2) Falls prevention intervention versus another falls prevention intervention. The most common interventions tested were exercise as a single intervention, education as a single intervention, functional electrical stimulation and exercise plus education. The risk of bias of the included studies mixed, with nine studies demonstrating high risk of bias related to one or more aspects of their methodology. The evidence was uncertain regarding the effects of exercise versus control on falls rate (RaR of 0.68; 95% CI 0.43 to 1.06; very low-quality evidence), number of fallers (RR of 0.85; 95% CI 0.51 to 1.43; low-quality evidence) and adverse events (RR of 1.25; 95% CI 0.26 to 6.03; low-quality evidence). Data were not available on quality of life outcomes comparing exercise to control. The majority of other comparisons between falls interventions and controls demonstrated no evidence of effect in favour of either group for all primary outcomes. For the comparison of different falls prevention interventions, the heterogeneity of intervention types across studies prohibited the pooling of data. In relation to secondary outcomes, there was evidence of an effect in favour of exercise interventions compared to controls for balance function with a SMD of 0.50 (95% CI 0.09 to 0.92), self-reported mobility with a SMD of 16.30 (95% CI 9.34 to 23.26) and objective mobility with a SMD of 0.28 (95% CI 0.07 to 0.50). Secondary outcomes were not assessed under the GRADE criteria and results must be interpreted with caution.

AUTHORS' CONCLUSIONS

The evidence regarding the effects of interventions for preventing falls in MS is sparse and uncertain. The evidence base demonstrates mixed risk of bias, with very low to low certainty of the evidence. There is some evidence in favour of exercise interventions for the improvement of balance function and mobility. However, this must be interpreted with caution as these secondary outcomes were not assessed under the GRADE criteria and as the results represent data from a small number of studies. Robust RCTs examining the effectiveness of multifactorial falls interventions on falls outcomes are needed.

A Novel Head Mounted Display Based Methodology for Balance Evaluation and Rehabilitation

In this paper, we present a new augmented reality (AR) head mounted display (HMD)-based balance rehabilitation method. This method assesses the individual’s postural stability quantitatively by measuring head movement via the inertial measurement unit sensor integrated in the AR HMD. In addition, it provides visual feedback to train through holographic objects, which interacts with the head position in real-time. We implemented applications for Microsoft HoloLens and conducted experiments with eight participants to verify the method we proposed. Participants performed each of three postural tasks three times depending on the presence or absence of augmented reality, the center of pressure (COP) displacement was measured through the Wii Balance Board, and the head displacement was measured through the HoloLens. There are significant correlations (p < 0.05) between COP and head displacement and significant differences (p < 0.05) between with/without AR feedback, although most of them were not statistically significant likely due to the small sample. Despite the results, we confirmed the applicability and potential of the AR HMD-based balance rehabilitation method we proposed. We expect the proposed method could be used as a convenient and effective rehabilitation tool for both patients and therapists in the future.

Meta-analysis and GRADE profiles of exercise interventions for falls prevention in long-term care facilities

AIMS

To provide a comprehensive collection of evidence on the effectiveness of exercise interventions to prevent falls and support clinical decision-making.

DESIGN

A systematic literature review and meta-analysis of randomized controlled trails were performed by combining trials from published systematic reviews and more recent ones from a separate literature search.

DATA SOURCES

The literature search was performed using PubMed, CINAHL, Cochrane Databases, and Google Scholar dating January 2007 - March 2018.

REVIEW METHODS

Comparable studies were pooled using the random-effects model. The GRADE approach was used to judge the evidence.

RESULTS

Exercises with a balance component or with technical devices reduced falls significantly, however, with low confidence in the evidence. The evidence indicated that exercises conducted longer than 6 months were beneficial. In frail residents, exercise interventions seemed to have substantially negative effects on falls.

CONCLUSIONS

Exercise interventions with technical devices, those with a balance component, and those performed longer than 6 months are recommended in long-term care settings. Frail residents need special attention when performing exercises due to their increased risk of falling.

IMPACT

Exercises with a balance component and exercises carried out with technical devices have beneficial effects, whereas exercises performed longer than 6 months are more effective than short-term performances. No significant reduction or decrease in the number of falls was found for exercise in cognitively impaired residents. In frail residents, however, the number of fall events increased substantially as a result of exercise interventions. The results of this review are useful for clinical decision-makers in long-term care facilities with regard to the planning and performance of exercise interventions for residents.

An investigation into the impact and implications of published papers from retracted research: systematic search of affected literature

OBJECTIVE

Analyses of the impact of a body of clinical trial reports subject to research misconduct have been few. Our objective was to examine the impact on clinically relevant research of a group of researchers' trial reports ('affected trial reports') affected by research misconduct, and whether identification of misconduct invoked a reappraisal.

DESIGN

In 2016, we used five databases and search engines to identify 'citing publications', that is, guidelines, systematic and other reviews, and clinical trials citing any of 12 affected trial reports, published 1998-2011, eventually retracted for research misconduct. The affected trial reports were assessed more likely to have had impact because they had hip fracture outcomes and were in journals with impact factor >4. Two authors assessed whether findings of the citing publications would change if the affected trial reports were removed. In 2018, we searched for evidence that the citing publications had undertaken a reassessment as a result of the potential influence of the affected trial reports.

RESULTS

By 2016 the affected trial reports were cited in 1158 publications, including 68 systematic reviews, meta-analyses, narrative reviews, guidelines and clinical trials. We judged that 13 guidelines, systematic or other reviews would likely change their findings if the affected trial reports were removed, and in another eight it was unclear if findings would change. By 2018, only one of the 68 citing publications, a systematic review, appeared to have undertaken a reassessment, which led to a correction.

CONCLUSIONS

We found evidence that this group of affected trial reports distorted the evidence base. Correction of these distortions is slow, uncoordinated and inconsistent. Unless there is a rapid, systematic, coordinated approach by bibliographic databases, authors, journals and publishers to mitigate the impact of known cases of research misconduct, patients, other researchers and their funders may continue to be adversely affected.

Practical tips for prescribing exercise for fall prevention

CLINICAL RELEVANCE

There is strong evidence from meta-analyses that exercise as a single intervention can reduce the number and risk of falls in community-dwelling older adults, yet not all types of exercise are equal.

OBSERVATIONS

Programs that include 3 h a week of exercise and provide a high challenge to balance can reduce falls by almost 40%. Reactive and volitional stepping interventions have also been shown to reduce falls by about 50%. Evidence is less clear regarding the efficacy of exercise in individuals who have experienced a stroke, who live in long-term care, who have been recently discharged from the hospital, or who have visual impairments, but there is some evidence that multifactorial programs may be useful.

CONCLUSION

Depending on the population, exercise as a single or as part of a multifactorial intervention may be beneficial in reducing falls.

Evaluating the use of multiteam systems to manage the complexity of inpatient falls in rural hospitals

OBJECTIVE

To evaluate the implementation and outcomes of evidence-based fall-risk-reduction processes when those processes are implemented using a multiteam system (MTS) structure.

DATA SOURCES/STUDY SETTING

Fall-risk-reduction process and outcome measures from 16 small rural hospitals participating in a research demonstration and dissemination study from August 2012 to July 2014. Previously, these hospitals lacked a fall-event reporting system to drive improvement.

STUDY DESIGN

A one-group pretest-posttest embedded in a participatory research framework. We required hospitals to implement MTSs, which we supported by conducting education, developing an online toolkit, and establishing a fall-event reporting system.

DATA COLLECTION

Hospitals used gap analyses to assess the presence of fall-risk-reduction processes at study beginning and their frequency and effectiveness at study end; they reported fall-event data throughout the study.

PRINCIPAL FINDINGS

The extent to which hospitals implemented 21 processes to coordinate the fall-risk-reduction program and trained staff specifically about the program predicted unassisted and injurious fall rates during the end-of-study period (January 2014-July 2014). Bedside fall-risk-reduction processes were not significant predictors of these outcomes.

CONCLUSIONS

Multiteam systems that effectively coordinate fall-risk-reduction processes may improve the capacity of hospitals to manage the complex patient, environmental, and system factors that result in falls.

New developments in our understanding of vitamin metabolism, action and treatment

Although vitamin D has been reported to have pleiotropic effects including effects on the immune system and on cancer progression, the principal action of vitamin D is the maintenance of calcium and phosphate homeostasis. The importance of vitamin D in this process is emphasized by the consequences of vitamin D deficiency which includes rickets in children and osteomalacia in adults. Vitamin D deficiency has also been reported to increase the risk of falls and osteoporotic fractures. Although vitamin D fortification of foods (including dairy products) has contributed to a marked decrease in rickets in the Western world, vitamin D deficiency in children and adults is still prevalent world-wide. This review summarizes new developments in our understanding of vitamin D endocrine system and addresses clinical syndromes related to abnormalities in vitamin D metabolism and action. In addition, the current understanding of the evaluation of vitamin D deficiency and sufficiency and recommendations for achieving vitamin D sufficiency are discussed.

Physical performance reflects cognitive function, fall risk, and quality of life in community-dwelling older people

This report searched for relationships between physical performance and other health indices through a detailed investigation of a randomly sampled cohort from a basic town resident registry. Residents between the age of 50 and 89 years were randomly sampled from the basic resident registry of a cooperating town for construction of a 415-participant cohort that minimized selection bias. Cognitive function measures, annual fall frequency, and SF-8 as an HRQOL measure were the outcomes of interest. The impact of physical function on outcomes was predicted using multivariate regression models with age and gender as covariates. Knee muscle strength, grip strength, one-leg standing time, and two-step test score had a significant impact on cognitive scores and SF-8 physical component summary scores. A shift of -1 standard deviation for grip strength, the stand-up test, and the two-step test increased fall risk by 39%, 23%, and 38%, respectively. In conclusion, diminished physical performance is related to serious problems in older individuals, specifically cognitive deterioration, increased fall risk, and inability to maintain HRQOL. These factors are independent of age and gender. Thus, the higher physical function can be maintained in older people, the better the other conditions appear to remain.

The economic case for prevention of population vitamin D deficiency: a modelling study using data from England and Wales

BACKGROUND

Vitamin D deficiency (VDD) affects the health and wellbeing of millions worldwide. In high latitude countries such as the United Kingdom (UK), severe complications disproportionally affect ethnic minority groups.

OBJECTIVE

To develop a decision-analytic model to estimate the cost effectiveness of population strategies to prevent VDD.

METHODS

An individual-level simulation model was used to compare: (I) wheat flour fortification; (II) supplementation of at-risk groups; and (III) combined flour fortification and supplementation; with (IV) a 'no additional intervention' scenario, reflecting the current Vitamin D policy in the UK. We simulated the whole population over 90 years. Data from national nutrition surveys were used to estimate the risk of deficiency under the alternative scenarios. Costs incurred by the health care sector, the government, local authorities, and the general public were considered. Results were expressed as total cost and effect of each strategy, and as the cost per 'prevented case of VDD' and the 'cost per Quality Adjusted Life Year (QALY)'.

RESULTS

Wheat flour fortification was cost saving as its costs were more than offset by the cost savings from preventing VDD. The combination of supplementation and fortification was cost effective (£9.5 per QALY gained). The model estimated that wheat flour fortification alone would result in 25% fewer cases of VDD, while the combined strategy would reduce the number of cases by a further 8%.

CONCLUSION

There is a strong economic case for fortifying wheat flour with Vitamin D, alone or in combination with targeted vitamin D3 supplementation.
