Functional Outcomes of Open Reduction and Internal Fixation in Proximal Humerus Fractures by Philos Plate

INTRODUCTION Proximal humerus fractures are one very common and usually occur in elderly people. These fractures are usually associated with some degree of comminution and deformity. Therefore, good anatomical reduction of fracture fragments and early mobilization are the main component for optimal outcomes of involved limb. This study was intended to evaluate the functional outcome of proximal humerus fracture in adults managed by open reduction and internal fixation (ORIF) by proximal humerus interlocking osteosynthesis (PHILOS) plate. MATERIAL AND METHODS This prospective and observational hospital based study was carried out in Orthopedics Department of Universal College of medical Sciences-Teaching Hospital (UCMS-TH) from October 2021 to September 2023. All patients with proximal humerus fractures who fulfilled the inclusion criteria and who underwent open reduction and internal fixation by PHILOS plate were enrolled in the study. Functional outcome was assessed according to Constant murley scoring system and Visual analogue score. Post-operatively patients were regularly followed at 6 weeks, 3 months and 6 months. RESULTS In this study of 60 cases, the mean age group was 55.38±11.40 years and male patients outnumbered female patients (39 males and 21 females). 36 cases (60%) were of right side and 24 (40%) were of left side. Majority of the fractures were due to fall injury (57%) followed by road traffic accident (35%). The mean Constant Murley Score was 78.15±5.620 and VAS (visual analogue score) was 1.88±0.865. CONCLUSION Open reduction and internal fixation by PHILOS plate is an effective procedure providing good anatomical restoration and early mobilization in proximal humerus fracture thus providing good functional outcome.

A dynamic spatiotemporal model for fall warning and protection.

Early detection of falls is important for reducing fall injuries. However, existing fall detection strategies mostly focus on reducing impact injuries rather than avoiding falls. This study proposed the concept of identifying "Imbalance Point" to warn the body imbalance, allowing sufficient time to recover balance. And if falling cannot be avoided, an impact sign is released by detecting the "Fall Point" prior to the impact. To achieve this goal, motion prediction model and balance recovery model are integrated into a spatiotemporal framework to analyze dynamic and kinematic features of body motion. Eight healthy young volunteers participated in three sets of experiment: Normal trial, Recovery trial and Fall trial. The body motion in the trials was recorded using Microsoft Azure Kinect. The results show that the developed algorithm for Fall Point detection achieved 100% sensitivity and 98.6% specificity, along with an average lead time of 297ms. Moreover, Imbalance Point was successfully detected in all Fall trials, and the average time interval between Imbalance Point and Fall Point was 315ms, longer than reported step reaction time for elderly (approximately 270ms). The experiment results demonstrate that the developed algorithm have great potential for fall warning and protection in the elderly.

Management of Splenic Injury at B&C Medical College, Teaching Hospital and Research Centre

Background: In all blunt abdominal injuries splenic injury relates to about 40%. Splenectomy is the preferred treatment choice for blunt splenic injury in hemodynamically unstable patients. The low-grade splenic injuries and stable patients are mostly treated by non-operative management (NOM) at today era. Consensuses have not been yet formulated about the management of high-grade splenic injuries in hemodynamically stable patients. So, this study analyzes the treatment of patients with high-grade splenic injuries in our institution. Methods: This study includes all the patients with splenic injuries presented to our hospital during the 5 years period from 2017 to 2022. The datas regarding primary baseline at emergency, complications and mortality were collected from the patient records at medical record section. Based on splenic injury and the treatment they received, they were grouped accordingly. Results: In a total of 38 cases of spleen injuries, the most common mode of injury was a road traffic accident (RTA) 84% followed by fall injury (10%) spontaneous rupture of the spleen and blast injury 3% each. Sixty-six per cent of the cases underwent operative management out of which 96% cases had a splenectomy and 4% cases had a splenic repair. There was 5% mortality and 95% recovery without residual morbidity. Conclusion: Most of the cases with spleen injury were managed with a favorable outcome. The careful patient selection for non-operative management will result in higher splenic salvage with close monitoring in an intensive care unit.

Pre-oxygenation using high-flow nasal oxygen versus tight facemask in trauma patients undergoing emergency anaesthesia.

Patients suffering from major traumatic injuries frequently require emergency anaesthesia. Due to often compromised physiology and the time-sensitive management, trauma patients may be more prone to desaturate during induction of anaesthesia. We hypothesised that pre-oxygenation using high-flow nasal oxygen would decrease the risk of desaturation during induction of anaesthesia in trauma patients and the study therefore aimed to compare the frequency of desaturation when pre-oxygenation was performed with high-flow nasal oxygen or a traditional facemask. This exploratory, prospective, before-and-after study was conducted at the Karolinska University Hospital, Sweden. Adult (≥18 years of age) patients suffering major traumatic injuries needing emergency anaesthesia were included around the clock. Patients were pre-oxygenated using a tight-fitting facemask during the first nine months of enrollment. High-flow nasal oxygen was then introduced as a method for pre-oxygenation of trauma patients. The primary outcome was the proportion of patients desaturating <93% during induction of anaesthesia, assessed from the start of pre-oxygenation until one minute after intubation. Secondary outcomes included perceived difficulty of pre-oxygenation among anaesthetists (assessed on a scale between 1 and 10) and safety outcomes, such as incidence of regurgitations and intracranial gas (assessed radiologically). Data from 96 patients were analysed. Facemask pre-oxygenation was performed in 66 patients, while 30 patients were pre-oxygenated with high-flow nasal oxygen. The most frequent trauma mechanisms were stabbing injuries (n = 34 (35%)) and fall injuries (n = 21 (22%)). There were no differences in patient characteristics between the groups. Eight (12%) versus three (10%) patients desaturated <93% in the facemask and high-flow nasal oxygen group respectively, OR 0.81 (95% CI 0.20-3.28), p = .76. Anaesthetists assessed pre-oxygenation using high-flow nasal oxygen as easier compared to facemask pre-oxygenation. No patient in any group showed signs of regurgitation. Among patients with facial or skull fractures requiring anaesthesia before radiology was performed, intracranial gas was seen in four (40%) patients pre-oxygenated with a facemask and in no patient pre-oxygenated with HFNO (p = .23). In this prospective study investigating trauma patients undergoing emergency anaesthesia, we could not see any difference in the number of patients desaturating when pre-oxygenation was performed with high-flow nasal oxygen compared to a tight-fitting facemask. Pre-oxygenation using high-flow nasal oxygen was assessed as easier compared to facemask pre-oxygenation.

FALL ENCOUNTERS AMONG OLDER ADULTS: IMPACT OF COVID-19

Abstract It was suspected that the restrictions in activity and clinical care during the COVID-19 pandemic would result in increased fall risks and falls in older populations. To explore the impact of the pandemic on falls, we examined the trajectory of fall rates among older adults cared for through a large, multi-state, Midwest healthcare system. De-identified medical record data was used to measure falls presenting to emergency, urgent, and hospital care in adults age 50+ from April 2019 through September 2022. We compared the fall rate during the pre-and post-COVID-19 time periods. Differences in fall rates were compared based on age groups, gender, race, and neighborhood socioeconomic status (nSES). The overall fall rate after COVID onset was significantly greater compared to prior to before COVID (11.59; 95%CI:11.50-11.67 vs. 11.20; 95%, CI:11.06-11.33). While White patients had a significantly higher rate of falls post-pandemic, changes in fall rates did not differ based on age, gender, or race. The changes did vary based on nSES, with the lower groups experiencing the largest increases. Findings may be related to differences in access to care and other services both early in the pandemic and as restrictions were lifted. Given the high cost of fall injuries, further work is needed to reduce falls and injuries in older adults.

Fall risk and cardiovascular outcomes of first-line antihypertensive medications in nursing home residents.

Little evidence exists about the comparative effects of first-line antihypertensive medications (i.e., renin-angiotensin-aldosterone converting enzyme inhibitors (RAASi), amlodipine, or thiazide diuretics) in older adults with limited life expectancy. We compared the rates of injurious falls and short-term cardiovascular events between different first-line antihypertensive medication classes in adults receiving care in nursing homes (NH). This was a retrospective cohort of Medicare fee-for-service beneficiaries receiving care in NHs. Patients newly dispensed first-line antihypertensive medications were identified using Part D claims (2015-2018) and linked with clinical assessments (i.e., Minimum Data Set). Fall-related injuries (FRI), hip fractures, and major adverse cardiac events (MACE) outcomes were identified using hospitalization claims. Patients were followed from the date of antihypertensive dispensing until the occurrence of outcomes, death, disenrollment, or 6-month follow-up. Inverse-probability-of-treatment-weighted (IPTW) cause-specific hazards regression models were used to compare outcomes between patients who were new users of RAASi, amlodipine, or thiazides. Our cohort included 16,504 antihypertensive users (RAASi, n = 9574; amlodipine, n = 5049; thiazide, n = 1881). Mean age was 83.5 years (± 8.2), 70.6% were female, and 17.2% were non-white race. During a mean follow-up of 5.3 months, 326 patients (2.0%) experienced an injurious fall, 1590 (9.6%) experienced MACE, and 2123 patients (12.9%) died. The intention-to-treat IPTW hazard ratio (HR) for injurious falls for amlodipine (vs RAASi) use was 0.85 (95% confidence interval (CI) 0.66-1.08) and for thiazides (vs RAASi) was 1.22 (95% CI 0.88-1.66). The rates of MACE were similar between those taking anti-hypertensive medications. Thiazides were discontinued more often than other classes; however, inferences were largely unchanged in as-treated analyses. Subgroup analyses were generally consistent. Older adults with limited life expectancy experience similar rates of injurious falls and short-term cardiovascular events after initiating any of the first-line antihypertensive medications.

Simultaneous determination of four phytoecdysteroids by LC-MS/MS: application to a comparative pharmacokinetic study in normal and adjuvant arthritis rats after oral administration of C. officinalis Kuan phytoecdysteroids extract

C. officinalis Kuan is the dry root of Cyathula officinalis Kuan. Clinically, it is used for fall and flutter injury, rheumatism and arthralgia. Phytoecdysteroids have significant anti-inflammatory effects, and the phytoecdysteroids present in C. officinalis Kuan exhibit potential for treating rheumatoid arthritis. This study first developed a selective, accurate and efficient LC-MS/MS method for 12-day pharmacokinetic studies regarding the simultaneous determination of cyasterone, 25-epi-28-epi-cyasterone, precyasterone and capitasterone from C. officinalis Kuan phytoecdysteroids extract in normal and adjuvant arthritis rats. An Agilent Eclipse Plus C18 RRHD column (1.8 µm, 50mm × 2.1 mm) with a gradient mobile phase consisting of water (A) and acetonitrile (B) was used for analysis. The mass analysis was performed in an Agilent 6430 QQQ-MS mass spectrometer with positive mode multiple reaction monitoring (MRM). The results indicated that the AUC0-t and AUC0-∞ values of the four phytoecdysteroids in adjuvant arthritis rats were different from those in normal rats on the first day, which could provide a helpful reference for pharmacological and toxicological studies, as well as clinical applications of C. officinalis Kuan in the treatment of rheumatoid arthritis.

Examination of Risk Factors Associated With Falls and Injurious Falls in People With Multiple Sclerosis: An Updated Nationwide Study

ObjectiveTo provide an update on risk factors associated with falls and injurious falls among people with multiple sclerosis (PwMS) in the United States. DesignNationwide cross-sectional web-based survey. SettingCommunity setting. ParticipantsAdult PwMS (n=965). InterventionsNot applicable. Main Outcome MeasuresParticipants completed self-report surveys of demographics, clinical data, concerns about falling, occurrence of falls, factors associated with falls, and injurious falls in the past 6 months. Participants also completed Patient-Reported Outcomes Measurement Information System (PROMIS) measures of depression, pain interference, and physical function, and the Fatigue Severity Scale. ResultsThe most common self-reported factors associated with falls included personal factors such as poor balance (75%), muscle weakness (54%), and/or fatigue (35%), environmental factors such as general surface conditions (37%) and/or distraction (15%), and activities-related factors such as urgency to complete a task (35%) and/or multitasking (27%). Logistic regression analyses indicated that higher fatigue severity (OR=1.19, P<.01) and higher pain interference (OR=1.02, P<.01) were associated with higher odds of experiencing at least 1 fall. Any level of concern, even minimal concern about falling was also significantly associated with a higher odd of experiencing at least 1 fall (ORs range 2.78 - 3.95, all P<.01). Fair to very high concerns about falling compared with no concern about falling (ORs range=5.17 – 10.26, all P<.05) was significantly associated with higher odds of sustaining an injurious fall. ConclusionsFindings suggest falls prevention approaches in PwMS should be multifactorial and include personal, environmental, and activities-related factors. Particular attention on fatigue, pain, and concern about falling may be needed to reduce incidence of falls and injurious falls in this population.

Machine-Learning Assessed Abdominal Aortic Calcification is Associated with Long-Term Fall and Fracture Risk in Community-Dwelling Older Australian Women.

Abdominal aortic calcification (AAC), a recognized measure of advanced vascular disease, is associated with higher cardiovascular risk and poorer long-term prognosis. AAC can be assessed on dual-energy X-ray absorptiometry (DXA)-derived lateral spine images used for vertebral fracture assessment at the time of bone density screening using a validated 24-point scoring method (AAC-24). Previous studies have identified robust associations between AAC-24 score, incident falls, and fractures. However, a major limitation of manual AAC assessment is that it requires a trained expert. Hence, we have developed an automated machine-learning algorithm for assessing AAC-24 scores (ML-AAC24). In this prospective study, we evaluated the association between ML-AAC24 and long-term incident falls and fractures in 1023 community-dwelling older women (mean age, 75 ± 3 years) from the Perth Longitudinal Study of Ageing Women. Over 10 years of follow-up, 253 (24.7%) women experienced a clinical fracture identified via self-report every 4-6 months and verified by X-ray, and 169 (16.5%) women had a fracture hospitalization identified from linked hospital discharge data. Over 14.5 years, 393 (38.4%) women experienced an injurious fall requiring hospitalization identified from linked hospital discharge data. After adjusting for baseline fracture risk, women with moderate to extensive AAC (ML-AAC24 ≥ 2) had a greater risk of clinical fractures (hazard ratio [HR] 1.42; 95% confidence interval [CI], 1.10-1.85) and fall-related hospitalization (HR 1.35; 95% CI, 1.09-1.66), compared to those with low AAC (ML-AAC24 ≤ 1). Similar to manually assessed AAC-24, ML-AAC24 was not associated with fracture hospitalizations. The relative hazard estimates obtained using machine learning were similar to those using manually assessed AAC-24 scores. In conclusion, this novel automated method for assessing AAC, that can be easily and seamlessly captured at the time of bone density testing, has robust associations with long-term incident clinical fractures and injurious falls. However, the performance of the ML-AAC24 algorithm needs to be verified in independent cohorts. © 2023 The Authors.

Incidence of cervical spine injuries in paediatric patients and their outcome in tertiary care hospital

Objective: The incidence of mortality after cervical trauma in the pediatric population is very high. The purpose of this study was to determine the treatment given, morbidity and mortality of patients with cervical spine injuries, and their outcome after 6 months of management which includes both surgical and conservative treatment. Materials &amp; Methods: A prospective study was conducted at Lady Reading Hospital, Peshawar with a total number of patients n = 187 included in our study. Patients were stratified according to their age, mortality, mechanism of injury (fall, motor vehicle accident, bicycle injuries, &amp;sports-related injuries), level of cervical spine injury, presence of neurologic deficit, presence of bony injury (fractures, &amp;dislocations), ligamentous injuries &amp; SCIWORA. The primary outcome was the functional status at 6 months following treatment. Results: There were 78 females and 109 males. In comparison to the lower cervical spine (C3 – C7), which was involved in 86 patients (46%), the higher cervical spine level (C0 – C2) was involved in 101 patients (or 54%). The most frequent cause of cervical spine injuries in the older age range was a history of a fall, followed by a motor vehicle accident. Among the treatment groups, mortality was highest in patients who underwent surgery. Conclusion: Younger age groups, higher cervical spine levels, and mechanisms of injury such as high energy impact trauma were independent risk factors for increased mortality. Compared to incomplete neurological abnormalities, a complete neurological disability increases mortality.

Ocular Trauma among Patients Visiting the Outpatient Department of Ophthalmology in a Tertiary Care Centre.

Ocular trauma is an important cause of blindness and ocular morbidity worldwide. Knowledge of the cause of eye injuries can guide preventive strategies and optimize management capacity. The aim of the study was to find out the prevalence of ocular trauma among patients visiting the outpatient Department of Ophthalmology in a tertiary care centre. A descriptive cross-sectional study was conducted among patients with ocular trauma from 10 January 2023 to 5 July 2023 after obtaining ethical approval from the Institutional Review Committee. A convenience sampling method was used. The point estimate was calculated at a 95% Confidence Interval. Among 4,959 patients, 107 (2.16%) (1.76-2.56, 95% Confidence Interval) had ocular trauma. Among them, 24 (22.43%) had occular trauma due to fall injuries. Ocular trauma was observed in 82 (76.64%) males and the common agent was blunt objects seen in 56 (52.34%). The prevalence of ocular trauma among patients was lower than in other studies done in similar settings. blunt injuries; injury; ophthalmology; prevalence.

Cost of U.S emergency department and inpatient visits for fall injuries in older adults

BackgroundFalls are a leading cause of injury and hospital readmissions in older adults. Understanding the distribution of acute treatment costs across inpatient and emergency department settings is critical for informed investment and evaluation of fall prevention efforts. MethodsThis study used the 2016–2018 National Inpatient Sample and National Emergency Department Sample. Annual treatment cost of fall injury among adults 65 years and older was estimated from charges, applying cost-to-charge and professional fee ratios. Weighted multivariable generalized linear models were used to separately estimate cost for inpatient and emergency department (ED) setting by injury type and individual demographic and health characteristics after adjusting for payer and hospital level characteristics. ResultsOlder adults incurred an estimated 922,428 inpatient and 2.3 million ED visits annually due to falls with combined annual costs of $19.8 billion. Over half of inpatient visits for fall injury were for fracture. Notably, 23% of inpatient visits were for fractures other than hip fracture and 14% of inpatient visits were for multiple fractures with costs totaling $3.4 billion and $2.5 billion, respectively. Annual ED costs were driven by superficial injury totaling $1.5 billion. Cost of ED visits were higher for adults 85 years and older (adjusted cost ratio (aCR): 1.11, 95% Confidence Interval (CI)I: 1.11–1.12) and those with dementia (aCR: 1.14, 95% CI: 1.13–1.15). Higher inpatient and ED visit cost was also associated with high-energy falls and discharge to post-acute care. ConclusionThe study found that more than 3 million older adults in the United States seek hospital care for fall injuries annually, a major concern given increasing capacity strain on hospitals and EDs. The $20 billion in annual acute treatment costs attributed to fall injury indicate an urgent need to implement evidence-based fall prevention interventions and underscores the importance of newly launched ED-based fall prevention efforts and investments in geriatric emergency departments.

Staff’s insights into fall prevention solutions in long-term care facilities: a cross-sectional study

BackgroundFalls are one of the most common and serious health issues in long-term care facilities (LTCFs), impacting not just residents, but staff and the healthcare system. This study aimed to explore LTCF staff’s current practices around falls prevention, and their suggested solutions for better falls prevention.MethodsIn the southwest of Ireland, a descriptive cross-sectional study was conducted in 13 LTCF sites, across a range of provider types and facility sizes. A survey, measuring staff knowledge, skills and attitudes, was distributed in physical and online formats. Staff suggestions for prioritising fall and fall-related injury prevention activities, and current staff practices regarding fall incidents were also sought. Content analysis was used to analyse responses, mapping categories and subcategories to the refined theoretical domains framework (TDF) and to an existing fall prevention guideline.ResultsThere were 155 respondents (15% response rate), from staff of the LTCFs. Environmental reviews and modifications (aligned to the TDF environmental context and resource domain) were the most common suggestions for preventing both falls and fall-related injuries. Other common suggestions for preventing falls were staff education, monitoring of residents, and using alarm/calling systems, while few staff members, across all roles, reported assessing residents, exercises, reviewing medications, and vitamin D supplements. For preventing fall-related injuries, suggestions included protective equipment, hip protectors and alarm/calling systems. Staff used a standardised approach when responding to a fall incident, with intensive and holistic post-fall control measures. HCAs focussed on transferring residents safely, while nurses of all grades focused more on post-fall assessment. Respondents believed that staff education, communication, increasing staffing levels and enhancing specialist care could support their practice.ConclusionNoting the low response rate, the results suggest an awareness gap regarding some evidence-based, resident-focussed falls prevention solutions, such as pro-active fall-risk assessment, exercise, medication review, and Vitamin D supplements. These aspects should be included in future fall prevention education programmes in LTCFs.

A core outcome set for evaluating the effectiveness of mixed-diagnosis falls prevention interventions for people with Multiple Sclerosis, Parkinson’s Disease and stroke

Introduction Clinical trials evaluating the effectiveness of falls prevention interventions for people with Multiple Sclerosis (MS), Parkinson’s Disease (PD) and stroke measure heterogeneous outcomes, often omitting those meaningful to patients. A core outcome set (COS) is a standardised set of outcomes that should be assessed in all trials within a research area. The aim of this study was to develop a COS for evaluating mixed-diagnosis falls prevention interventions for people with MS, PD and stroke in non-acute and community settings, with input from relevant stakeholder groups. Methods Previously published research undertaken by the team, including a qualitative study with 20 patients and a review of the literature, were used to derive a longlist of potential outcomes. Outcomes were prioritised for inclusion in the COS using a three-round online Delphi survey. A multi-stakeholder, consensus meeting was conducted to agree upon the final COS and to provide a recommendation for a single outcome measure for each outcome in the COS. Results Forty-eight participants were recruited across four stakeholder groups (researchers, patients, clinicians, and service-planners/policymakers). A total of 42 participants (87.5%) completed all three rounds of the surveys. Sixty-two outcomes were considered for inclusion in the COS throughout the Delphi process. A total of 15 participants attended the consensus meeting where they agreed upon the final COS and accompanying measurement instruments: fall incidence, injurious fall incidence, quality of life, falls self-efficacy, fear of falling, activity curtailment due to fear of falling, and cost-effectiveness. Attendees at the consensus meeting recommended that the proposed mechanism of impact of an intervention is considered when selecting additional outcomes outside of those in the COS to assess. Conclusions This study identified a COS for evaluating the effectiveness of mixed-diagnosis falls prevention interventions for people with MS, PD and stroke. It is recommended that this COS and accompanying measurement instruments be used in all future trials in this research area so that findings can be combined and compared.

Abstract 12225: The Association of Intensive Blood Pressure Therapy to Mortality in Older Adults After an Injurious Fall. Geriatric Insights From SPRINT

Introduction: The primary finding of the Systolic Blood Pressure Intervention Trial (SPRINT) demonstrated that intensive (IT, &lt;120 mmHg) compared to standard (&lt;140 mmHg) blood pressure (BP) treatment on an index serious adverse event (SAE), injurious falls, was similar. However, mortality after the index fall has not been well studied. We hypothesized that the occurrence of falls may be associated with reduced mortality benefits. Methods: Using the publicly available SPRINT dataset we analyzed the association of IT on the primary outcome of all-cause mortality and the secondary outcome of non-cardiovascular (CV) mortality as a function of falls. Results: Among 9,361 SPRINT participants, 7.1% (n=666) had a fall. Falls were more likely in older adults (p&lt;0.0001), among women (45.9% vs 34.8%), and those with baseline cardiovascular disease (20.3% vs 16.4%). Among those who fell, 7.8% (52/666) died which was 14.2% of all deaths in SPRINT (52/365). In those who fell, mortality increased with age (p&lt;0.0001) and was highest in those ≥ 80 years (13.7%, Figure ). For all-cause mortality- Falls independently and significantly were associated with increased risk (HR 1.41,1.04-1.91, p=0.03 ) while IT significantly decreased the risk (HR 0.73, 0.60-0.91, p=0.004) . The joint effect (IT+Fall) demonstrated a non-significant increased risk (HR 1.03, 0.56-1.88, p int =0.92). For non-CV mortality- Falls independently and significantly were associated with increased risk (HR 1.63, 1.16-2.29, p=0.005) while IT did not significantly lower risk (HR 0.81, 0.63-1.03, p=0.09) . The joint effect (IT+Fall) demonstrated a non-significant increased risk (HR 1.21, 0.63-2.35, p int =0.56). Conclusions: Our findings suggest that current reporting of potential harm of the treatment effects of IT, measured by the index SAE, may underrepresent true risk and overstate treatment benefits.

The influence of assistive technology and home modifications on falls in community-dwelling older adults: a systematic review protocol

BackgroundFall-related injuries can reduce older adults’ independence and result in economic burdens. The assistive technologies and home modifications explored in this review are suggested to reduce the risk of falls of community-dwelling older people. However, the location of the in-home assistive technology being used, and the in-home modification likely interact and influence fall reduction and injury prevention of community-dwelling older adults. This interactive effect is poorly understood. A better understanding of the impact of assistive technologies and modifications in the homes of older adults is needed to support the appropriate application of these devices.ObjectiveThe objective of this systematic review is to detail the contribution of assistive technology and home modification on falls, fall frequency, fall severity, and fall location within the homes of community-dwelling older adults.MethodsWe will source articles from 3 databases (MEDLINE, CINAHL, Web of Science Core Collection) and will assess them using a set of pre-defined inclusion and exclusion criteria. Reporting will be in accordance with PRISMA 2020. Two independent reviewers will screen each study at the title and abstract and full-text level. We are managing citations within the Covidence software. Data extraction and analysis will be reported in a systematic review.DiscussionThe outcome variables of interest are fall frequency, fall location, injury, mortality, and hospitalization. These variables of interest all relate to falls, their severity, and their locations in the home. We are seeking a better understanding of how these outcomes vary with the use of different assistive technologies and home modifications as reported in the literature. This will help us understand where falls occur which may inform how different assistive technologies can be used by community-dwelling older adults to prevent falls and adverse outcomes in different areas of their homes. Our review will provide a basis for more intentional prescription of ambulatory assistive technologies and evidence-based recommendations of home modifications. It may also inform adaptations to existing technologies to foster safer mobility in the homes of community-dwelling older adults.Systematic review registrationThis protocol has been submitted for registration in PROSPERO CRD42022370172 on October 24, 2022.

Economic burden and financial vulnerability of injuries among the elderly in Vietnam

Falls are a leading cause of death among elderly people. However, research on the cost of fall-related injuries is limited in Vietnam. We estimated treatment costs and associated factors among 405 elderly patients in Thai Binh hospitals. Costs were estimated through self-reported data on medical and non-medical expenses. Logistic regression and GLM were used to identify payment and affordability factors. Inpatient and outpatient care costs for fall-related injuries were US$98.06 and US$8.53, respectively. 11.85% of participants couldn’t pay for treatment. Payment ability and cost decline were linked to family income, medical history, and hospital stay length. Elderly with fall-related injuries in Vietnam experienced high costs and severe health issues. Primary healthcare services and communication campaigns should be strengthened to reduce disease burden and develop effective fall injury prevention strategies.

Factors Associated with Acute Injurious Falls in Elderly Hospitalized Patients: A Multicenter Descriptive Study.

The Centers for Medicare & Medicaid Services Hospital-Acquired Conditions (CMS-HAC) links Medicare payments to health care quality. Experiencing a serious disability or death associated with a fall in a health care facility based on diagnosis codes has been identified as an opportunity for improvement. Multiple factors contribute to an inpatient fall, including medications that affect cognition in older adults. The primary aim of this study was to investigate the effect of the commonly prescribed classes of medications on the CMS-HAC falls and trauma definition in US hospitals in a large inpatient database from 2019 to 2021. The authors analyzed data from 835 hospitals in the Vizient Clinical Data Base between January 1, 2019, and December 31, 2021, on patients ≥ 65 years of age with CMS-HAC patient falls and trauma codes. Using logistic regression and stepwise Poisson regression analysis, the authors identified demographic, clinical, and hospital-related variables associated with falls meeting the CMS-HAC definition. The top 20 prescribed drug classes in these patients were also identified. Among 11,064,024 patient encounters, 5,978 met the CMS-HAC definition of a serious fall. Patients who experienced a serious fall were significantly more likely to be > 79 years of age (p < 0.001, odds ratio [OR] 1.30, 95% confidence interval [CI] 1.23-1.37), have a history of prior falls (p < 0.001, OR 2.30, 95% CI 2.11-2.50), have a code for dementia (p < 0.001, OR 1.50, 95% CI 1.40-1.60), and have higher anticholinergic cognitive burden (ACB) scores (p < 0.001, OR 1.14, 95% CI 1.13-1.14). Specific medication classes associated with CMS-HAC falls were first-generation antihistamines (p < 0.00, OR 1.21, 95% CI 1.09-1.35), second-generation antihistamines (p ≤ 0.001, OR 1.15, 95% CI 1.13-1.19), and atypical antipsychotics (p < 0.001, OR 1.18, CI 1.13-1.29). Patients who experience a fall meeting the CMS-HAC fall definition are significantly more likely to have a prior history of falling, dementia, and a higher ACB score. Results from this study may inform future quality improvement work aimed at reducing injurious falls.
