Impact attenuation provided by older adult protective headwear products during simulated fall-related head impacts.

ABSTRACT:

Introduction

While protective headwear products (PHP) are designed to protect older adults from fall-related head injuries, there are limited data on their protective capacity. This study's goal was to assess the impact attenuation provided by commercially available PHP during simulated head impacts.

Methods

A drop tower and Hybrid III headform measured the decrease in peak linear acceleration (g _atten ) provided by 12 PHP for front- and back-of-head impacts at low (clinically relevant: 3.5 m/s) and high (5.7 m/s) impact velocities.

Results

The range of g _atten across PHP was larger at the low velocity (56% and 41% for back and frontal impacts, respectively) vs. high velocity condition (27% and 38% for back and frontal impacts, respectively). A significant interaction between impact location and velocity was observed (p < .05), with significantly greater g _atten for back-of-head compared to front-of-head impacts at the low impact velocity (19% mean difference). While not significant, there was a modest positive association between g _atten and product padding thickness for back-of-head impacts (p = .095; r = 0.349).

Conclusion

This study demonstrates the wide range in impact attenuation across commercially available PHP, and suggests that existing products provide greater impact attenuation during back-of-head impacts. These data may inform evidence-based decisions for clinicians and consumers and help drive industry innovation.

Can Fall Risk Screening and Fall Prevention Advice in Hospital Settings Motivate Older Adult Patients to Take Action to Reduce Fall Risk?

Project description:ObjectiveWe investigated whether an in-hospital intervention consisting of fall risk screening and tailored advice could prompt patients to take preventive action.MethodPatients (≥70) attending the emergency department and nephrology outpatient clinic in a Dutch hospital were screened. Patients at high risk received tailored advice based on their individual risk factors. Three months after screening, preventive steps taken by patients were surveyed.ResultsTwo hundred sixteen patients were screened. Of the 83 patients completing a 3-month follow-up, 51.8% took action; among patients who received tailored advice (n = 20), 70% took action. Patients most often adhered to advice on improving muscle strength and undergoing vision checkups (20%). Tailored advice and a reported low quality of life were associated with consulting a health care provider.DiscussionPatients at risk in these settings are inclined to take action after screening. However, they do not always adhere to the tailored prevention advice.

Implementing STEADI in Academic Primary Care to Address Older Adult Fall Risk.

Project description:Background and objectivesFalls are the leading cause of injury-related deaths in older adults. Objectives include describing implementation of the Centers for Disease Control and Prevention's Stopping Elderly Accidents, Deaths, and Injuries (STEADI) initiative to help primary care providers (PCPs) identify and manage fall risk, and comparing a 12-item and a 3-item fall screening questionnaire.Design and methodsWe systematically incorporated STEADI into routine patient care via team training, electronic health record tools, and tailored clinic workflow. A retrospective chart review of patients aged 65 and older who received STEADI measured fall screening rates, provider compliance with STEADI (high-risk patients), results from the 12-item questionnaire (Stay Independent), and comparison with a 3-item subset of this questionnaire (three key questions).ResultsEighteen of 24 providers (75%) participated, screening 773 (64%) patients over 6 months; 170 (22%) were high-risk. Of these, 109 (64%) received STEADI interventions (gait, vision, and feet assessment, orthostatic blood pressure measurement, vitamin D, and medication review). Providers intervened on 85% with gait impairment, 97% with orthostatic hypotension, 82% with vision impairment, 90% taking inadequate vitamin D, 75% with foot issues, and 22% on high-risk medications. Using three key questions compared to the full Stay Independent questionnaire decreased screening burden, but increased the number of high-risk patients.Discussion and implicationsWe successfully implemented STEADI, screening two-thirds of eligible patients. Most high-risk patients received recommended assessments and interventions, except medication reduction. Falls remain a substantial public health challenge. Systematic implementation of STEADI could help clinical teams reduce older patient fall risks.

Factors influencing older adult community fall prevention exercise implementation: a scoping review.

Project description:Exercise that challenges balance is the most effective fall prevention intervention in community-dwelling older adults. Identifying factors influencing implementation of community fall prevention exercise programs is a critical step in developing strategies to support program delivery. To identify implementation facilitators, barriers, and details reported in peer-reviewed publications on community fall prevention exercise for older adults. Scoping review. We searched multiple databases up to July 2023 for English-language publications that reported facilitators and/or barriers to implementing an evidence-based fall prevention exercise program in adults aged 50+ years living independently. At least two reviewers independently identified publications and extracted article, implementation, and exercise program characteristics and coded barriers and facilitators using the Consolidated Framework for Implementation Research (CFIR). We included 22 publications between 2001 and July 2023 that reported factors influencing implementation of 10 exercise programs. 293 factors were reported: 183 facilitators, 91 barriers, 6 described as both a facilitator and barrier, and 13 unspecified factors. Factors represented 33 CFIR constructs across all five CFIR domains: implementation inner setting (n = 95 factors); innovation (exercise program) characteristics (n = 84); individuals involved (n = 54); implementation process (n = 40) and outer setting (n = 20). Eight publications reported implementation strategies used; 6 reported using a conceptual framework; and 13 reported implementation outcomes. The high number of factors reflects the complexity of fall prevention exercise implementation. The low reporting of implementation strategies, frameworks and outcomes highlight the ongoing need for work to implement and sustain community fall prevention exercise programs.

Care provided by older adult caregivers to a spouse in active cancer treatment: a scoping review.

Project description:PurposeDue to population aging, the number of older adults with cancer will double in the next 20 years. There is a gap in research about older adults who are the caregiver of a spouse with cancer. Therefore, this review seeks to answer the overarching research question: What is known about the association of providing care on Health-Related Quality of Life (HRQOL), psychological distress, burden, and positive aspects of caregiving for an older adult caregiver to a spouse with cancer?MethodsThis scoping review was guided by the framework of Arksey and O'Malley and refined by Levac et al. Comprehensive search strategies were conducted in Medline, Excerpta Medica Database (EMBASE), PsycINFO, and Cumulative Index to Nursing and Allied Health Literature (CINAHL) from inception until April 15, 2021. Two independent reviewers screened abstracts, full text, and completed data abstraction. A gray literature search and two stakeholder consultations were conducted.ResultsA total of 8132 abstracts were screened, and 17 articles were included. All studies outlined caregivers provided preventive, instrumental, and protective care to a spouse in active cancer treatment. However, the time spent on caregiving was rarely examined (n = 4). Providing care had a negative association on HRQOL, perceived burden, and psychological distress outcomes. Five studies examined positive experiences of caregivers.ConclusionThe scoping review findings highlight the informal care provided by older adult caregivers to a spouse with cancer and how the care provided is associated with HRQOL, burden, psychological distress, and the positive aspects of caregiving.

Occupational Therapy and the Use of Technology on Older Adult Fall Prevention: A Scoping Review.

Project description:Introduction: Falls are the second leading cause of accidental or non-intentional deaths worldwide and are the most common problem as people age. The primary purpose of addressing falls is to detect, prevent, treat, and reduce their incidence and consequences. Previous studies identified that multifactorial programs, an interprofessional team, and assistive technology are required to address falls in older adults effectively. Accordingly, the research question is as follows: what are the scope, type of studies, and approaches and strategies to fall risk using technology in the existing occupational therapy literature regarding interventions to address the effects of falls in older adults on daily living? Methods: This scoping review was carried out in January 2020 through Biblioteca Virtual de Salud España, C.I.N.A.H.L., Cochrane Plus, OTSeeker, PubMed, Scopus, and Web of Science. Results: Twelve papers were included. We analyzed the year and journal of publication, authors' affiliation, and design of the study, and thematic categories. There were three themes: participants' characteristics, type of intervention, and fall approach and type of technology used. Discussion and Conclusions: The literature obtained is scarce. It is considered to still be an emerging theme, especially when considering the use of technology for occupational therapy.

Gas loss in simulated galaxies as they fall into clusters.

Project description:We use high-resolution cosmological hydrodynamic galaxy formation simulations to gain insights into how galaxies lose their cold gas at low redshift as they migrate from the field to the high-density regions of clusters of galaxies. We find that beyond three cluster virial radii, the fraction of gas-rich galaxies is constant, representing the field. Within three cluster-centric radii, the fraction of gas-rich galaxies declines steadily with decreasing radius, reaching <10% near the cluster center. Our results suggest galaxies start to feel the effect of the cluster environment on their gas content well beyond the cluster virial radius. We show that almost all gas-rich galaxies at the cluster virial radius are falling in for the first time at nearly radial orbits. Furthermore, we find that almost no galaxy moving outward at the cluster virial radius is gas-rich (with a gas-to-baryon ratio greater than 1%). These results suggest that galaxies that fall into clusters lose their cold gas within a single radial round-trip.

Older adult fall prevention practices among primary care providers at accountable care organizations: A pilot study.

Project description:BackgroundFalls are a serious and common problem among older adults. Low-tech, inexpensive, community-based fall prevention programs have been shown to be both effective and cost effective, however, these programs are not well-integrated into clinical practice.Research designWe surveyed primary care providers at a convenience sample of two accountable care organizations in Massachusetts to assess their beliefs, attitudes, knowledge, and practices relative to fall risk assessment and intervention for their older patients.ResultsResponse rate was 71%. Providers' beliefs about the efficacy of fall risk assessment and intervention were mixed. Eighty-seven percent believed that they could be effective in reducing fall risk among their older adult patients. Ninety-six percent believed that all older adults should be assessed for fall risk; and, 85% believed that this assessment would identify fall risk factors that could be modified. Nonetheless, only 52% believed that they had the expertise to conduct fall risk assessment and only 68% believed that assessing older adult patients for fall risk was the prevailing standard of practice among their peer providers. Although most providers believed it likely that an evidence-based program could reduce fall risk among their patients, only 14% were aware of the Centers for Disease Control and Prevention's fall risk assessment algorithm (STEADI Toolkit), and only 15% were familiar with Matter of Balance, the most widely disseminated community fall risk prevention program in Massachusetts.DiscussionNew strategies that more directly target providers are needed to accelerate integration of fall risk assessment and intervention into primary care practice.

Simulated weightlessness procedure, head-down bed rest impairs adult neurogenesis in the hippocampus of rhesus macaque.

Project description:The microgravity environment in space can impact astronauts' cognitive and behavioral activities. However, due to the limitations of research conditions, studies of biological changes in the primate brain, such as neurogenesis, have been comparatively few. We take advantage of - 6° head-down bed rest (HDBR), one of the most implemented space analogue on the ground, to investigate the effects of weightlessness on neurogenesis of non-human primate brain. Rhesus Macaque monkeys were subjected to HDBR for 42 days to simulate weightlessness. BrdU (5-bromodeoxyuridin) and IdU (iododeoxyuridine) were intraperitoneally injected separately before or after HDBR to label the survival and proliferation of newborn neurons. Immunohistochemistry was performed to study the effect of simulated weightlessness on neurogenesis. BrdU staining showed that survival of newborn neurons was reduced, while there were fewer BrdU-positive neurons in the HDBR group compared with the control. Furthermore, IdU-positive neurons also decreased in the HDBR group suggesting a reduced proliferation capacity for these newborn neurons. Our results demonstrate the definite neurogenesis in the adult rhesus macaque hippocampus, and simulated weightlessness HDBR procedure impairs the adult neurogenesis.

Development of a Hybrid Simulated Patient Experience to Practice Care of the Dying Older Adult.

Project description:IntroductionCare of the dying older adult includes critical skills that emerging physicians should master but are not consistently taught. Simulation has been shown to be an excellent tool for teaching these skills in a standardized fashion. Simulation allows direct observation to assess and provide learner feedback. Our goal was to develop a learning activity to practice skills caring for the older adult at the end of life and identify areas in need of improvement.MethodsWe developed a hybrid simulation in which fourth-year medical students and internal medicine (IM) residents cared for a 70-year-old patient (Laerdal SimMan 3G) who was actively dying in the emergency department. He was accompanied by his wife (standardized patient) and a nurse (standardized role). Over the academic year 2012-2013, we observed and videotaped 83 fourth-year medical students and 22 first-year IM residents in this setting. We assessed the learners' completion of 15 tasks associated with good end-of-life care.ResultsAll learners demonstrated professional activity working with the nurse, and all medical students but one gave opioids appropriately for pain. Only 19% of the medical students appropriately disclosed the patient's status to the wife using the words death and/or dying, and only 50% of the IM residents did so.DiscussionWe successfully developed a learning activity in which learners can practice their skills caring for the dying older adult. We also determined that there is opportunity for improvement concerning communication, especially with the use of the words death and dying.

Machine learning versus binomial logistic regression analysis for fall risk based on SPPB scores in older adult outpatients.

Project description:ObjectiveTo compare the performance of the diagnostic model for fall risk based on the short physical performance battery (SPPB) developed using commercial machine learning software (MLS) and binomial logistic regression analysis (BLRA).MethodsWe enrolled 797 out of 850 outpatients who visited the clinic between March 2016 and November 2021. Patients were categorized into the development (n = 642) and validation (n = 155) datasets. Age, sex, number of comorbidities, number of medications, body mass index (BMI), calf circumference (left-right average), handgrip strength (left-right average), total SPPB score, and history of falls were determined. We defined fall risk by an SPPB score of ≤6 in men and ≤9 in women. The main metrics used for evaluating the machine learning model and BLRA were the area under the curve (AUC), accuracy, precision, recall (sensitivity), specificity, and F-measure. The commercial MLS automatically calculates the parameter range of the highest contribution.ResultsThe participants included 797 outpatients (mean age, 76.3 years; interquartile range, 73.0-81.0; 288 men). The metrics of the current diagnostic model in the commercial MLS were as follows: AUC = 0.78, accuracy = 0.74, precision = 0.46, recall (sensitivity) = 0.81, specificity = 0.71, F-measure = 0.59. The metrics of the current diagnostic model in the BLRA were as follows: AUC = 0.77, accuracy = 0.75, precision = 0.47, recall (sensitivity) = 0.67, specificity = 0.77, F-measure = 0.55. The risk factors for falls in older adult outpatients were handgrip strength, female sex, experience of falls, BMI, and calf circumference in the commercial MLS.ConclusionsThe diagnostic model for fall risk based on SPPB scores constructed using commercial MLS is noninferior to BLRA.
