Introduction: Over the last decade, Transportation Network Companies (TNCs) have emerged as a popular mobility option. Yet past research has not conclusively established the linkage between their service operations and road crash risk. Our analysis compares road crash outcomes in San Francisco between 2010, when TNCs were negligible, and 2016, when they comprised 15% of vehicle trips within San Francisco. Method: We estimated a fixed-effects Poisson regression model for four crash outcomes, controlling for the change in background traffic, speed, and time-invariant factors including roadway geometry. Results: Our results show that TNCs have three competing influences on crashes: (a) they increase total vehicle miles traveled (VMT) and thus crashes; (b) VMT on TNCs themselves is associated with fewer crashes, potentially due to a newer vehicle fleet or the selection of drivers; and (c) TNC pick-ups and drop-offs are associated with more crashes, potentially due to more conflicts at the curb. We apply these models to estimate the number of crashes expected from a counterfactual 2016 scenario without TNCs and compare that to the with-TNC scenario to isolate the total effect of TNCs. This model application reveals that TNCs are associated with a 4% decrease in total crashes. We also find that TNCs are associated with a slight reduction in fatal and injury crashes, crashes involving a bicyclist or pedestrian, and alcohol-involved crashes, but the results are not statistically significant for these crash types. Practical applications: By disaggregating TNC services into distinct operational components, our research provides valuable insights for urban transport planners and policymakers seeking to maximize the safety benefits of emerging transportation technology while mitigating their associated risks.
在过去的十年中,交通网络公司(TNCs)已经成为一种流行的出行选择。然而,过去的研究并没有最终确定它们的服务运营与道路碰撞风险之间的联系。我们的分析比较了2010年旧金山的道路交通事故结果,当时跨国公司几乎可以忽略不计,而2016年,跨国公司占旧金山车辆出行的15%。方法:我们估计了四种碰撞结果的固定效应泊松回归模型,控制了背景交通、速度和包括道路几何形状在内的时不变因素的变化。结果:我们的研究结果表明,跨国公司对撞车事故有三个相互竞争的影响:(a)它们增加了车辆行驶总里程(VMT),从而增加了撞车事故;(b)跨国公司的车辆行驶里程本身与较少的撞车事故有关,可能是由于车队较新或选择了司机;(c)跨国公司上下车与更多车祸有关,这可能是由于路边的冲突更多。我们应用这些模型来估计没有跨国公司的2016年反事实情景的预期撞车次数,并将其与有跨国公司的情景进行比较,以隔离跨国公司的总影响。该模型应用表明,跨国公司与总事故减少4%有关。我们还发现,跨国公司与致命和伤害事故、涉及骑自行车者或行人的事故以及涉及酒精的事故的轻微减少有关,但这些事故类型的结果在统计上并不显著。实际应用:通过将跨国公司服务分解为不同的运营组件,我们的研究为城市交通规划者和政策制定者提供了有价值的见解,以寻求最大限度地提高新兴交通技术的安全效益,同时降低相关风险。

Objectives: This retrospective observational study utilized sociodemographic and neighborhood characteristics of child non-motorists (CNMs) involved in motor-vehicle crashes (MVCs) in Utah (2019–2021), examined neighborhood sociodemographic disparities of the aforementioned CNMs, and explored the differences in CNM incidence between highly vulnerable neighborhoods and other areas. Methods: All children less than 18 years old involved in a pedestrian, cyclist, or nonmotorized scooter/skater versus motor-vehicle crash in Utah from January 1, 2019 to December 31, 2021 were included in the study population. Characteristics of CNMs and associated MVCs were reported overall and compared by occupant types. Neighborhood Area Deprivation Index (ADI), Child Opportunity Index (COI), and Social Vulnerability Index (SVI) percentile scores and quintiles were compared between CNMs, child vehicle occupants (CVOs), and all Utah children. Annual CNM incidence was compared between highly vulnerable census tracts and other areas. All group comparisons were conducted using the Kruskal-Wallis tests, Wilcoxon rank-sum tests, and Chi-square tests, with p-values < 0.05 considered statistically significant. Results: A total of 1,055 MVCs involving 1,115 CNMs were included in the analysis. The majority of MVCs occurred in metropolitan areas, between September and May, on weekdays, and during typical work hours. Children were predominantly male and at least 10 years old. Neighborhoods of child pedestrians ranked higher across all three indices for sociodemographic disparities compared to neighborhoods of child cyclists (p = 0.002 for ADI; p < 0.001 for SVI/COI). A higher proportion of CNMs resided in the most deprived neighborhoods compared to CVOs and general children population. Higher CNM incidence was observed in tracts with greater vulnerability and lower opportunity levels. Conclusions: Significant differences in neighborhood sociodemographic disparities were observed across occupant types and between CNMs, CVOs, and all Utah children. This study underscores the need for multifaceted approaches to improve the safety of CNMs in Utah.
目的:本回顾性观察研究利用了犹他州(2019-2021年)涉及机动车碰撞(MVCs)的儿童非驾驶员(CNM)的社会人口统计学和社区特征,检查了上述CNM的社区社会人口统计学差异,并探讨了高度脆弱社区与其他地区CNM发病率的差异。方法:研究人群包括2019年1月1日至2021年12月31日在犹他州发生的行人、骑自行车者或非机动滑板车/滑冰者与机动车碰撞的所有18岁以下儿童。对CNMs和相关MVCs的特征进行了总体报道,并按居住者类型进行了比较。比较CNMs、儿童车辆乘员(CVOs)和犹他州所有儿童的邻里区域剥夺指数(ADI)、儿童机会指数(COI)和社会脆弱性指数(SVI)百分位数和五分位数。比较了高度脆弱的人口普查区和其他地区的年CNM发病率。所有组间比较均采用Kruskal-Wallis检验、Wilcoxon秩和检验和卡方检验,p值<; 0.05认为有统计学意义。结果:共纳入1055个mvc,涉及1115个CNMs。大多数自杀式袭击发生在大都市地区,发生在9月至5月之间的工作日和典型工作时间。儿童主要是10岁以上的男性。与骑自行车的儿童社区相比,儿童步行社区在所有三个社会人口差异指数中排名更高(ADI为p = 0.002; SVI/COI为p <; 0.001)。与社区儿童和一般儿童相比,居住在最贫困社区的cnm比例更高。在易损性和机会水平较低的地区,CNM发病率较高。结论:社区社会人口统计学差异在不同居住类型、cnm、CVOs和所有犹他州儿童之间存在显著差异。这项研究强调需要采取多方面的方法来提高犹他州cnm的安全性。

Introduction: This study examines the neurocognitive foundations of work-related factors and their role in advancing occupational health psychology (OHP). It bridges gaps between neuroscience and OHP, exploring fields like health neuroscience and neuro-safety science, along with advancements in neurocognitive assessment and interdisciplinary collaboration. Method: A review of 96 studies and structural topic modeling proposes a framework integrating psychological theories with neurobiological insights to better understand workplace behaviors and neural mechanisms. Results: Key cognitive domains—attention, memory, executive functioning, and reaction time—are linked to safety–critical behaviors and decision-making. Using EEG and fMRI, the study introduces objective neural measures to complement self-reports, showing how stress and cognitive load affect performance. Conclusions and Practical Applications: Findings advance OHP theories, identifying neural markers of stress and human errors to guide interventions like neurofeedback and resilience programs. Innovations in neurocognitive assessment strengthen evidence-based strategies to enhance well-being, reduce risks, and improve organizational effectiveness, establishing a neuroscience-informed framework for workplace safety.

Background: The rate of active transportation to school has significantly declined in recent decades. Safety concerns are a primary factor contributing to this decrease. This study aims to identify factors that impact the safety of students’ bicycling chosen route including environmental features, social factors, as well as student and parent characteristics. Additionally, the study aims to evaluate the effectiveness of navigational applications such as Google Maps and Komoot in recommending safe cycling routes. Method: The study sample included 32 adolescents (10–15 years old) and one parent/guardian for each of the adolescents. The dataset consisted of GPS and video data recorded by helmet cameras during students’ bicycle trips to school. Furthermore, baseline surveys provided demographic information and bicycling habits from both adolescents and parents. To compare different routes, a safety score was calculated, derived from environmental factors, traffic conditions, and geometric features. Linear Mixed Models (LMM) were used to examine the relationship between potential predictors including adolescents and parents’ demographics and environmental characteristics and the safety score assigned to each route. Results: Younger students and those living in a more bike-friendly neighborhood chose safer routes to school. Participants rode on sidewalks more often when taking routes with lower safety scores, most likely to avoid traffic. Additionally, routes suggested by Komoot and the actual routes taken by students were safer than those suggested by Google Maps bike routing. Conclusion: The study’s findings emphasized the significance of bike infrastructure in improving the safety of young bicyclists and increasing the rate of active transportation to school. It also highlights the critical role of safety interventions and parents guiding their children in safe bicycling behaviors, as well as children learning and applying safe route selection skills. Practical Application: Enhancing bike infrastructure and refining navigational apps to prioritize safer routes can improve student cycling safety.
背景:近几十年来,主动交通工具上学的比率显著下降。安全问题是导致这一下降的主要因素。本研究旨在找出影响学生选择骑行路线安全性的因素,包括环境特征、社会因素以及学生和家长特征。此外,该研究旨在评估导航应用程序(如谷歌Maps和Komoot)在推荐安全骑行路线方面的有效性。方法:研究对象为32名10 ~ 15岁青少年,每名青少年1名家长/监护人。该数据集包括GPS和头盔摄像头在学生骑自行车上学时记录的视频数据。此外,基线调查提供了青少年和父母的人口统计信息和骑自行车习惯。为了比较不同的路线,根据环境因素、交通状况和几何特征计算出一个安全分数。使用线性混合模型(LMM)来检验潜在预测因子(包括青少年和父母的人口统计学和环境特征)与分配给每条路线的安全评分之间的关系。结果:年龄较小的学生和居住在更适合骑自行车的社区的学生选择了更安全的上学路线。当参与者选择安全得分较低的路线时,他们更经常在人行道上骑行,因为这些路线最有可能避开交通堵塞。此外,Komoot建议的路线和学生实际采取的路线比谷歌地图建议的自行车路线更安全。结论:研究结果强调了自行车基础设施在提高青少年骑自行车者的安全性和提高主动交通上学率方面的重要性。它还强调了安全干预措施和家长指导孩子安全骑自行车行为以及儿童学习和应用安全路线选择技能的关键作用。实际应用:加强自行车基础设施和改进导航应用程序,优先考虑更安全的路线,可以提高学生骑自行车的安全性。

Introduction: Surf lifesavers form a key part of Australia’s first responder workforce. Patrolling members can start from 13 years old, with potential exposure to traumatic incidents. Protective factors may mitigate the trauma exposure. This study investigated protective factors associated with mental health outcomes among adolescent surf lifesavers (13–17 years), including in response to exposure to potentially traumatic events. Methods: An online survey was developed to collect data from Australian surf lifesavers (13–17 years). Measures included demographic factors, stressful life events, post-traumatic stress symptoms (PTSS), self-efficacy, social support, and attitudes toward mental health problems. Hierarchical regressions and moderation analyses explored the relationships between variables. Results: There were 118 responses collected with overall mean age 15.4 years (SD = 1.3). PTSS was moderately to strongly positively correlated with all trauma domains. Higher self-efficacy and social support scores were correlated with lower PTSS. Hierarchical regression showed that Trauma within SLS, social support, self-efficacy and attitudes toward mental health were significantly associated with the outcome in the final regression model (F(5,110) = 17.87, p < 0.001), with the protective factors collectively explaining 28% of the variance in PTSS. Negative attitudes were positively associated with PTSS, while social support and self-efficacy scores were both negatively associated with PTSS. Conclusions: This study highlights the critical and protective interplay between social support, self-efficacy, mental health attitudes and trauma exposure among adolescent surf lifesavers. The findings will guide the development of targeted interventions to support younger patrolling members with an emphasis on supportive interventions to improve resilience and wellbeing in young emergency service personnel exposed to trauma. Practical applications: This study highlights the importance of encouraging protective factors with young individuals in emergency service roles, with practical implications for mental health professionals, emergency service agencies, surf lifesaving organizations, and policymakers interested in promoting the wellbeing of adolescent emergency service personnel.
简介:冲浪救生员是澳大利亚第一反应队伍的重要组成部分。巡逻队员可以从13岁开始,有可能接触到创伤性事件。保护性因素可能减轻创伤暴露。本研究调查了青少年冲浪救生员(13-17岁)心理健康结果的相关保护因素,包括对潜在创伤性事件的反应。方法:开展一项在线调查,收集澳大利亚冲浪救生员(13-17岁)的数据。测量包括人口统计学因素、压力生活事件、创伤后应激症状(PTSS)、自我效能、社会支持和对心理健康问题的态度。层次回归和适度分析探讨了变量之间的关系。结果:共收集118例应答者,总平均年龄15.4岁(SD = 1.3)。创伤后应激障碍与所有创伤领域呈正相关。较高的自我效能和社会支持得分与较低的创伤后应激障碍相关。层次回归显示,在最终回归模型中,创伤、社会支持、自我效能感和心理健康态度与ptsd的结果显著相关(F(5,110) = 17.87, p < 0.001),这些保护因素共同解释了28%的ptsd方差。消极态度与创伤后应激障碍呈正相关,而社会支持和自我效能得分与创伤后应激障碍均呈负相关。结论:本研究强调了青少年冲浪救生员的社会支持、自我效能感、心理健康态度与创伤暴露之间的关键和保护性相互作用。研究结果将指导制定有针对性的干预措施,以支持年轻的巡逻人员,重点是支持性干预措施,以提高遭受创伤的年轻应急服务人员的复原力和福祉。实际应用:本研究强调了在紧急服务角色中鼓励年轻人保护因素的重要性,对心理健康专业人员、紧急服务机构、冲浪救生组织和对促进青少年紧急服务人员福祉感兴趣的政策制定者具有实际意义。

Introduction: The variation in risk associated with well-known risk factors, like driver age or speed limits on public roads, has become smaller over time. For driver age, this can be shown as a “flattening” of risk: The U-shaped curve showing the variation in accident rate by driver age is getting flatter. Method: This paper asks how this trend can best be described. It is shown that two measures of variation in risk, relative risk and population attributable risk, do not capture the trend towards less variation in risk. It is shown that the trend towards less variation in risk is associated with a reduction of the relative contribution of systematic variation in the number of accidents to the distribution of accidents between the units (drivers, road sections, etc.) of a population at risk. Results: Based on this, it is proposed that accident rates can be interpreted as expected values of Poisson distributions. One may then generate synthetic mixed Poisson distributions and by comparing these for different points in time show that a reduced variation in risk implies that the distribution of accidents is becoming more random. Conclusions: The distribution of accidents in populations at risk (drivers, road segments, etc.) is becoming more random (i.e., it contains less systematic variation than earlier). Practical applications: Randomness does not imply unpreventability. Examples are given of how accidents can be prevented in a population where the distribution is random. The paper is based on data for Norway, and no claim is made that the trends examined in the paper apply to all countries.
导言:随着时间的推移,与众所周知的风险因素相关的风险变化,如司机年龄或公共道路上的速度限制,已经变得越来越小。对于司机的年龄,这可以表现为风险的“平坦化”:显示事故率随司机年龄变化的u形曲线越来越平坦。方法:本文询问如何最好地描述这种趋势。研究表明,风险变化的两种衡量标准,即相对风险和人口归因风险,并不能反映风险变化趋向于减少的趋势。研究表明,风险变化的趋势与事故数量的系统变化对处于危险中的人群的单位(司机、路段等)之间的事故分布的相对贡献的减少有关。结果:在此基础上,提出事故率可以用泊松分布的期望值来解释。然后,人们可以生成合成的混合泊松分布,并通过比较不同时间点的这些分布,表明风险变化的减少意味着事故的分布变得更加随机。结论:事故在危险人群(驾驶员、路段等)中的分布正变得更加随机(即,它比以前包含更少的系统变化)。实际应用:随机性并不意味着不可预防。文中给出了在随机分布的人群中如何预防事故的例子。这篇论文基于挪威的数据,并没有声称论文中研究的趋势适用于所有国家。

Introduction: The advancement of advanced driver assistance systems (ADAS) aims to enhance driving safety, efficiency, and convenience. However, their potential remains underutilized as drivers frequently disengage or avoid using these systems. This study investigates the phenomenon of ADAS disuse, encompassing situational disengagement and systematic avoidance, through in-depth interviews with SAE Level 2 automated vehicle drivers. Method: Using thematic analysis, we identified nine key themes influencing disuse across three domains: Driving task (strategic, tactical, and operational level of driving tasks); Human (sense of control, knowledge, trust, and responsibility); and Environment (road users and road situation). Results: Drivers cited discomfort with system aggressiveness, lack of trust in detection capabilities, and incompatibility with their driving styles as critical factors. Environmental complexities, such as construction zones and pedestrian-heavy areas, further exacerbated disengagement. Additionally, legal and moral responsibility emerged as influences on drivers’ preferences for manual control. Conclusions: Our findings underscore the need for adaptive, user-centered designs prioritizing trust, transparency, and context-sensitive system behaviors. By addressing these barriers, ADAS can achieve safer and more consistent adoption, supporting broader goals of accident prevention and traffic efficiency. Practical Applications: This study provides insights for enhancing ADAS design and fostering driver confidence, paving the way for their effective integration into modern mobility solutions.
导读:先进驾驶辅助系统(ADAS)的发展旨在提高驾驶的安全性、效率和便利性。然而,由于驾驶员经常脱离或避免使用这些系统,它们的潜力仍未得到充分利用。本研究通过对SAE 2级自动驾驶汽车驾驶员的深度访谈,调查了ADAS的废弃现象,包括情景脱离和系统回避。方法:通过主题分析,我们确定了影响弃用的九个关键主题,涉及三个领域:驾驶任务(驾驶任务的战略、战术和操作层面);人(控制感、知识感、信任感和责任感);环境(道路使用者和道路情况)。结果:驾驶员将系统侵略性的不适、对检测能力的缺乏信任以及与驾驶风格的不兼容列为关键因素。环境的复杂性,如建筑区和行人密集的地区,进一步加剧了脱离接触。此外,法律和道德责任也会影响驾驶员对手动控制的偏好。结论:我们的研究结果强调了自适应的、以用户为中心的设计需要优先考虑信任、透明度和上下文敏感的系统行为。通过解决这些障碍,ADAS可以实现更安全、更一致的采用,从而支持更广泛的事故预防目标和交通效率。实际应用:本研究为改进ADAS设计和培养驾驶员信心提供了见解,为ADAS与现代移动解决方案的有效整合铺平了道路。

The effect of voluntary driver's licence surrender on road crashes caused by older drivers 自愿交出驾驶执照对高龄司机造成的交通事故的影响
IF 4.4 2区 工程技术 Q1 ERGONOMICS Pub Date : 2025-12-01 Epub Date: 2025-10-11 DOI: 10.1016/j.jsr.2025.10.005

Introduction: As the older population grows, the number of road crashes caused by older drivers has consistently increased at an average of 3.7% per year over the past five years in South Korea. To address this issue, since 2019 the South Korean government has promoted a program of voluntary driver’s license surrender (particularly among older drivers) that provides transport cards worth 100,000 to 200,000 Korean currency for voluntarily surrendering licenses. Method: This study aims to analyze the effect of voluntary driver's license surrender on road crashes caused by older drivers using the Comparison Group method. The number of crashes, the number of fatal crashes, and the number of serious injury crashes are compared before and after introduction of voluntary surrender program. The effects are examined in detail in terms of the ages of older drivers, the surrender rates, and the types of local areas like urban or rural areas. Results: The results indicate that voluntary driver's license surrender significantly reduced the number of fatal and serious injury crashes among older drivers. In particular, it was found that age group 75 and older showed the highest reduction of crashes in all age groups and that the cities and counties with the higher rate of driver’s license surrender showed higher crash reductions. The reduction was also higher in rural areas compared to urban areas.
导语:随着老年人口的增长,在过去的五年里,韩国因老年司机导致的道路交通事故数量以平均每年3.7%的速度持续增长。为了解决这一问题,韩国政府从2019年开始推行了自愿交出驾照(特别是老年司机)计划,为自愿交出驾照的人提供价值10万至20万韩元的交通卡。方法:本研究采用比较组法,分析自愿交出驾驶证对老年驾驶员道路交通事故的影响。比较了自愿自首制度实施前后的车祸数量、致命车祸数量和重伤车祸数量。研究人员从老年司机的年龄、退让率以及城市或农村等地区的类型等方面详细考察了这些影响。结果:自愿交出驾照显著降低了老年司机的致命和严重伤害事故数量。特别是,在所有年龄组中,75岁及以上年龄组的车祸减少率最高,而且交出驾照率较高的城市和县的车祸减少率也较高。农村地区的降幅也高于城市地区。

Background: Firefighters face significant occupational hazards resulting in fatal and nonfatal injuries as well as illnesses. This study characterizes the costs of workers’ compensation (WC) claims among Ohio firefighters from 2001 to 2020, providing insights for prevention and resource allocation strategies. Methods: WC claims data for public and private fire departments were analyzed. Claims were categorized by type (medical-only vs. lost-time), demographics, tasks that led to the injury/illness, injury/illness events, and diagnoses. Costs included medical care, indemnity payments, and reserves for future anticipated costs, evaluated as of Q2 2022. Results: Among 37,306 claims, costs totaled $542 million. Lost-time claims accounted for $497 million, while medical-only claims totaled $45 million. Overexertion involving outside sources was the most frequent event, contributing to 27% of claims and $176 million in costs. Patient care activities and long-term exposures had disproportionately high cost-to-claim ratios, highlighting their significant financial burden. A notable increase in cancer-related claims was observed following Ohio’s firefighter cancer presumption law implementation in 2017, reflecting the impact of policy changes on claim trends. Conclusions: This analysis highlights the substantial cost of WC claims among firefighters, emphasizing the need for targeted prevention efforts and resource allocation. The findings underscore the impact of policy changes, such as presumption laws, in shaping WC trends. Future research could examine cost differences across firefighter subgroups and assess the long-term impacts of presumption laws on compensation systems. Practical Applications: Insights from this study provide fire departments and policymakers with critical data to prioritize prevention strategies for high cost injuries, such as overexertion and cancer-related conditions. Findings also support the development of policies and resource allocations aimed at improving firefighter safety.
背景:消防员面临严重的职业危害,导致致命和非致命伤害以及疾病。本研究分析了2001年至2020年俄亥俄州消防员工伤赔偿(WC)索赔的成本特征,为预防和资源分配策略提供了见解。方法:对公共和私人消防部门的WC索赔数据进行分析。索赔按类型(仅医疗与损失时间)、人口统计、导致伤害/疾病的任务、伤害/疾病事件和诊断进行分类。费用包括医疗保健、赔款和未来预期费用的准备金,截至2022年第二季度进行评估。结果:在37,306起索赔中,费用总计为5.42亿美元。损失时间索赔占4.97亿美元,而仅医疗索赔总额为4500万美元。与外部来源有关的过度劳累是最常见的事件,占索赔的27%,成本为1.76亿美元。患者护理活动和长期暴露具有不成比例的高成本-索赔比率,突出了他们的重大财务负担。2017年俄亥俄州实施消防员癌症推定法后,癌症相关索赔显著增加,反映了政策变化对索赔趋势的影响。结论:该分析强调了消防员WC索赔的巨大成本,强调了有针对性的预防工作和资源分配的必要性。研究结果强调了政策变化(如推定法)在塑造用水量趋势方面的影响。未来的研究可以检查消防员亚组之间的成本差异,并评估推定法对赔偿制度的长期影响。实际应用:本研究的见解为消防部门和政策制定者提供了关键数据,以优先考虑高成本伤害的预防策略,如过度劳累和癌症相关疾病。研究结果还支持制定旨在改善消防员安全的政策和资源分配。

Introduction: Work-related musculoskeletal disorders (WMSDs) are prevalent among healthcare professionals due to the physically demanding nature of their work environments. These disorders increase costs associated with workers’ compensation claims and healthcare services, reduce productivity, and negatively impact the quality of life for affected workers. Therefore, proper ergonomic risk assessment tools are vital for monitoring and preventing WMSDs among healthcare professionals. Method: This study provides a comprehensive overview of ergonomic risk assessment techniques used among healthcare workers. Following an extensive search, 31 studies published in English from 2014 to 2024 were identified. Results: With growing awareness of ergonomic risks in healthcare settings, research has explored various assessment methods to understand and mitigate these risks among healthcare workers across different disciplines. This finding highlights the significant role of self-reported and observation-based methods, despite potential subjective biases. Despite their challenges and underutilization, direct measurement methods have demonstrated substantial potential for enhancing ergonomic assessments when appropriately adapted to healthcare environments. Conclusions and practical applications: In future research, a longitudinal study design incorporating ergonomic risk assessment tools and hybrid methodologies integrating simulated settings with real-world observations should be employed to facilitate a comprehensive evaluation of ergonomic risks among healthcare professionals. This approach would contribute to the development of effective interventions aimed at mitigating WMSDs.
导读:工作相关的肌肉骨骼疾病(WMSDs)在医疗保健专业人员中很普遍,因为他们的工作环境对身体的要求很高。这些疾病增加了与工人索赔和医疗保健服务相关的成本,降低了生产率,并对受影响工人的生活质量产生了负面影响。因此,适当的人体工程学风险评估工具对于监测和预防医疗保健专业人员的WMSDs至关重要。方法:本研究提供了一个全面的概述人体工程学风险评估技术中使用的卫生保健工作者。经过广泛的搜索,确定了2014年至2024年用英语发表的31项研究。结果:随着人们对卫生保健环境中人体工程学风险的认识不断提高,研究人员探索了各种评估方法,以了解和减轻不同学科卫生保健工作者的这些风险。这一发现强调了自我报告和基于观察的方法的重要作用,尽管存在潜在的主观偏见。尽管存在挑战和未充分利用,但直接测量方法已显示出在适当适应医疗保健环境时加强人体工程学评估的巨大潜力。结论和实际应用:在未来的研究中,应该采用纵向研究设计,结合人体工程学风险评估工具和混合方法,将模拟环境与现实世界的观察相结合,以促进对医疗保健专业人员的人体工程学风险的综合评估。这种做法将有助于制定旨在减轻大规模杀伤性武器的有效干预措施。
