The Safe Home Care Intervention Study: Implementation Methods and Effectiveness Evaluation.

Home care (HC) aides experience numerous safety hazards in clients' homes; many hazards also put clients at risk. We hypothesized that safety coaching led by nurse managers (NMs) during their initial HC needs assessment could prompt clients to improve safety conditions in their homes. Following a 2-arm proof-of-concept intervention study design, intervention NMs used motivational interviewing (MI), facilitated by a safety handbook and video, to coach clients on home safety improvements. Control arm NMs performed intake assessments with no changes to usual practices. Intervention effectiveness was assessed by NMs and aides. Three HC agencies and two elder services contributed 35 intervention and 23 control homes. NMs coached 97% of clients and reported that 94% were engaged; 63% implemented improvements. NMs' and aides' assessments were consistent; homes with clients reported by NMs as resistant to safety changes had higher aides' hazard scores. Client coaching can be effective for improving HC safety.

Coaching Home Care Clients to Prepare Their Homes for Safe Care Visits: A Mixed-Methods Study to Evaluate a Nurse-Led Educational Intervention Process.

Assuring home care (HC) workers' safety is challenging because the work environment is a private home. This paper presents the process evaluation for a proof-of-concept safety intervention study to assess whether nurse-led safety coaching, using motivational interviewing and a safety handbook, could enable HC clients to improve safety in their homes. The process evaluation objectives were to (i) document the intervention's implementation progress and (ii) assess the intervention's dose delivery, dose reception, and fidelity. Five agencies employing liaisons (n = 5) and nurse managers (NMs, n = 8) implemented this study's intervention and control arms. NMs assigned to the intervention arm (n = 6) coached 34 clients. Process evaluation metrics were assessed with mixed-methods data from (i) surveys completed by NMs during the intervention, (ii) postintervention audio-recorded and transcribed interviews (n = 6) with NMs and liaisons, and (iii) study progress tracking tools. The delivered dose efficiency was 85%, measured by the distribution of safety handbook copies to clients. About 94% of clients (n = 32) were considered "engaged" or "maybe engaged" during the safety coaching. Most coached clients (n = 30) were reachable for follow-up by NMs to assess intervention progress. Despite challenges, the intervention was implemented with good fidelity. Safety coaching can be applied in many HC contexts in larger populations.

Aide and Client Safety "Should Go Hand-In-Hand": Qualitative Findings From Home Care Aides, Clients, and Agency Leaders.

Retention of the home care (HC) aide workforce is essential to meet the needs of our aging population. Some studies suggest that improving HC safety could increase job retention. This study objective was to explore qualitatively the connection between aide and client safety and factors impacting this care relationship. Data consisted of audio-recorded, verbatim responses to open-ended questions of two focus groups with aides (n = 10), two in-person interviews with HC agency managers, and 37 phone interviews with those working in (aides, n = 16; managers, n = 12) and receiving (clients, n = 9) HC. Clients reported home layout and accessibility as safety concerns. Aides and managers reported that client family members can make the care job more challenging. The aide-client connection was affected by communication style, family and HC agency support, allotted care time, and job task boundaries. Interventions that address the safety of both clients and aides can influence HC job satisfaction and retention.

Risk of Kidney Injury among Construction Workers Exposed to Heat Stress: A Longitudinal Study from Saudi Arabia.

Saudi Arabia (SA) is one of the hottest countries in the world. This study was conducted to assess the impact of summer heat stress in Southeastern SA on short-term kidney injury (KI) among building construction workers and to identify relevant risk factors. Measurements of urinary albumin-creatinine ratio (ACR), height, weight, hydration, symptoms, daily work and behavioral factors were collected in June and September of 2016 from a cohort of construction workers (n = 65) in Al-Ahsa Province, SA. KI was defined as ACR ≥30 mg/g. Multivariate linear regression analysis was used to assess factors related to cross-summer changes in ACR. A significant increase in ACR occurred among most workers over the study period; incidence of KI was 18%. Risk factors associated with an increased ACR included dehydration, short sleep, and obesity. The findings suggest that exposure to summer heat may lead to the development of KI among construction workers in this region. Adequate hydration and promotion of healthy habits among workers may help reduce the risk of KI. A reduction in work hours may be the most effective intervention because this action can reduce heat exposure and improve sleep quality.

A Field Evaluation of Construction Workers' Activity, Hydration Status, and Heat Strain in the Extreme Summer Heat of Saudi Arabia.

OBJECTIVES: Assess the impact of summer heat exposure (June-September) on residential construction workers in Al-Ahsa, Saudi Arabia by evaluating (i) heart rate (HR) responses, hydration status, and physical workload among workers in indoor and outdoor construction settings, (ii) factors related to physiological responses to work in hot conditions, and (iii) how well wet-bulb globe temperature-based occupational exposure limits (WBGTOELs) predict measures of heat strain. METHODS: Twenty-three construction workers (plasterers, tilers, and laborers) contributed 260 person-days of monitoring. Workload energy expenditure, HR, fluid intake, and pre- and postshift urine specific gravity (USG) were measured. Indoor and outdoor heat exposures (WBGT) were measured continuously and a WBGTOEL was calculated. The effects of heat exposure and workload on heart rate reserve (HRR), a measure of cardiovascular strain, were examined with linear mixed models. A metric called 'heat stress exceedance' (HSE) was constructed to summarize whether the environmental heat exposure (WBGT) exceeded the heat stress exposure limit (WBGTOEL). The sensitivity and specificity of the HSE as a predictor of cardiovascular strain (HRR ≥30%) were determined. RESULTS: The WBGTOEL was exceeded frequently, on 63 person-days indoors (44%) and 91(78%) outdoors. High-risk HRR occurred on 26 and 36 person-days indoors and outdoors, respectively. The HSE metric showed higher sensitivity for HRR ≥30% outdoors (89%) than indoors (58%) and greater specificity indoors (59%) than outdoors (27%). Workload intensity was generally moderate, with light intensity work more common outdoors. The ability to self-pace work was associated with a lower frequency of HRR ≥30%. USG concentrations indicated that workers began and ended their shifts dehydrated (USG ≥1.020). CONCLUSIONS: Construction work where WBGTOEL is commonly exceeded poses health risks. The ability of workers to self-pace may help reduce risks.

"That's not my job": A mixed methods study of challenging client behaviors, boundaries, and home care aide occupational safety and health.

INTRODUCTION: Home care (HC) aide is among the fastest-growing jobs. Aides often work in long-term care relationships with elders or people with disabilities in clients' homes, assisting with daily activities. The purpose of this mixed-methods paper is to elucidate aides' experiences around the boundary-challenging behaviors of clients asking for services beyond aides' job duties and to identify possible interventions. METHODS: A cross-sectional survey of HC aides in Massachusetts (n = 1249) provided quantitative data. Post-survey qualitative data were collected from nine HC aide focus groups (n = 70) and seven in-depth interviews with HC industry and labor representatives. RESULTS: Quantitatively, aides who reported often being asked to do tasks outside their job duties were more likely to report abuse (prevalence ratio [PR] = 1.93; 95%CI: 1.47-2.52 for verbal, PR = 1.81; 95%CI: 1.13-2.91 for physical/sexual) and pain/injury with lost work time or medical care (PR = 1.58; 95%CI: 1.11-2.25). They were also less likely to want to remain in their job (PR = 0.94; 95%CI: 0.89-1.00) or recommend it to others (PR = 0.94; 95%CI: 0.90-0.98). Qualitative data showed that clients' requests for tasks beyond job duties were frequent and can lead to injuries, abuse, and psychosocial stress. Yet, requests often reflected genuine need. Helping clients stay at home, compassion, and feeling appreciated contributed to job satisfaction; therefore, aides can feel conflicted about refusing requests. CONCLUSION: Client task requests outside HC services are a complex problem. Employer support, training, care plans, and feeling part of a care team can help aides navigate professional boundaries while delivering high quality care.

Home care aides' experiences of verbal abuse: a survey of characteristics and risk factors.

OBJECTIVE: Violence from care recipients and family members, including both verbal and physical abuse, is a serious occupational hazard for healthcare and social assistance workers. Most workplace violence studies in this sector focus on hospitals and other institutional settings. This study examined verbal abuse in a large home care (HC) aide population and evaluated risk factors. METHODS: We used questionnaire survey data collected as part of a larger mixed methods study of a range of working conditions among HC aides. This paper focuses on survey responses of HC aides (n=954) who reported on verbal abuse from non-family clients and their family members. Risk factors were identified in univariate and multivariable analyses. RESULTS: Twenty-two per cent (n=206) of aides reported at least one incident of verbal abuse in the 12 months before the survey. Three factors were found to be important in multivariable models: clients with dementia (relative risk (RR) 1.38, 95% CI 1.07 to 1.78), homes with too little space for the aide to work (RR 1.52, 95% CI 1.17 to 1.97) and predictable work hours (RR 0.74, 95% CI 0.58 to 0.94); two additional factors were associated with verbal abuse, although not as strongly: having clients with limited mobility (RR 1.35, 95% CI 0.94 to 1.93) and an unclear plan for care delivery (RR 1.27, 95% CI 0.95 to 1.69). Aides reporting verbal abuse were 11 times as likely to also report physical abuse (RR 11.53; 95% CI 6.84 to 19.45). CONCLUSIONS: Verbal abuse is common among HC aides. These findings suggest specific changes in work organisation and training that may help reduce verbal abuse.

Assessment of Heat Stress Exposure among Construction Workers in the Hot Desert Climate of Saudi Arabia.

OBJECTIVES: Excessive heat exposure poses significant risks to workers in hot climates. This study assessed the intensity and duration of heat stress exposure among workers performing residential construction in southeastern Saudi Arabia (SA) during the summer, June-September 2016. Objectives were to: identify work factors related to heat stress exposure; measure environmental heat exposure at the construction sites; assess the heat stress risk among workers using the wet bulb globe temperature (WBGT) index; and determine if temperature-humidity indices can be appropriate alternatives to WBGT for managing heat stress risk at the construction sites. METHODS: Worksite walkthrough surveys and environmental monitoring were performed, indoors and outdoors, at 10 construction sites in Al-Ahsa Province. A heat stress exposure assessment was conducted according to the American Conference of Governmental Industrial Hygienists (ACGIH®) guidelines, which uses the WBGT index. WBGT measurements from two instruments were compared. Alternative heat stress indices were compared to the WBGT: the heat index (HI) and humidex (HD) index. RESULTS: Construction workers were exposed to excessive heat stress, indoors and outdoors over a large part of the work day. Complying with a midday outdoor work ban (12-3 p.m.) was not effective in reducing heat stress risk. The highest intensity of exposure was outdoors from 9 a.m. to 12 p.m.; a period identified with the highest hourly mean WBGT values (31-33°C) and the least allowable working time according to ACGIH® guidelines. Comparison of the alternative indices showed that the HI is more reliable than the HD as a surrogate for the WBGT index in the climate studied. CONCLUSION: The extreme heat exposure represents a serious risk. The severity of heat stress and its impact are projected to increase due to climate change, emphasizing the need for immediate improvement of the current required protective measures and the development of occupational heat stress exposure guidelines in SA.

Risk of Sharps Injuries to Home Care Nurses and Aides: A Systematic Review and Meta-Analysis.

OBJECTIVE: To evaluate all available literature and develop a pooled estimate of the risk of sharps injuries (SI) among home care (HC) nurses and aides. METHODS: A systematic literature search was conducted and relevant articles were reviewed following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Primary outcome data from studies identified by the systematic review were pooled using a random effects model to calculate a summary measure of SI risk for nurses and for aides. RESULTS: Five articles were included in the final analysis. Nurses had a 5.25% weighted average risk of experiencing at least one SI in the past year while working in HC (95% confidence interval [CI]: 3.11% to 7.40%); aides pooled SI risk was 1.74% (95% CI: 0.72% to 2.77%). CONCLUSIONS: Combining findings of all available studies demonstrates that there is a serious risk of SI among both the HC nurses and aides.

Risk of sharps injuries among home care aides: Results of the Safe Home Care survey.

OBJECTIVES: Home care (HC) aides constitute an essential, rapidly growing workforce. Technology advances are enabling complex medical care at home, including procedures requiring the percutaneous use of sharp medical devices, also known as sharps. Objectives were to quantify risks of sharps injuries (SI) in a large HC aide population, compare risks between major occupational groups, and evaluate SI risk factors. METHODS: A questionnaire survey was administered to aides hired by HC agencies and directly by clients. One thousand one hundred seventy-eight aides completed questions about SI and potential risk factors occurring in the 12 months before the survey. SI rates were calculated and Poisson regression models identified risk factors. RESULTS: Aides had a 2% annual risk of experiencing at least 1 SI (95% confidence interval [CI], 1.1-2.6). Client-hired aides, men, and immigrants had a higher risk than their counterparts. Risk factors among all HC aides included helping a client use a sharp device (rate ratio [RR], 5.62; 95% CI, 2.75-11.50), observing used sharps lying around the home (RR, 2.68; 95% CI, 1.27-5.67), and caring for physically aggressive clients (RR, 2.82; 95% CI, 1.36-5.85). CONCLUSIONS: HC aides experience serious risks of SI. Preventive interventions are needed, including safety training for clients and their families, as well as aides.

Occupational health of home care aides: results of the safe home care survey.

OBJECTIVES: In countries with ageing populations, home care (HC) aides are among the fastest growing jobs. There are few quantitative studies of HC occupational safety and health (OSH) conditions. The objectives of this study were to: (1) assess quantitatively the OSH hazards and benefits for a wide range of HC working conditions, and (2) compare OSH experiences of HC aides who are employed via different medical and social services systems in Massachusetts, USA. METHODS: HC aides were recruited for a survey via agencies that employ aides and schedule their visits with clients, and through a labour union of aides employed directly by clients or their families. The questionnaire included detailed questions about the most recent HC visits, as well as about individual aides' OSH experiences. RESULTS: The study population included 1249 HC aides (634 agency-employed, 615 client-employed) contributing information on 3484 HC visits. Hazards occurring most frequently related to musculoskeletal strain, exposure to potentially infectious agents and cleaning chemicals for infection prevention and experience of violence. Client-hired and agency-hired aides had similar OSH experiences with a few exceptions, including use of sharps and experience of verbal violence. CONCLUSIONS: The OSH experience of HC aides is similar to that of aides in institutional healthcare settings. Despite OSH challenges, HC aides enjoy caring for others and the benefits of HC work should be enhanced. Quantification of HC hazards and benefits is useful to prioritise resources for the development of preventive interventions and to provide an evidence base for policy-setting.

A growing fire hazard concern in communities: home oxygen therapy and continued smoking habits.

The Safe Home Care Project investigated both qualitatively and quantitatively a range of occupational safety and health hazards, as well as injury and illness prevention practices, among home care aides in Massachusetts. This article reports on a hazard identified by aides during the study's initial focus groups: smoking by home care clients on long-term oxygen therapy. Following the qualitative phase we conducted a cross-sectional survey among 1,249 aides and found that medical oxygen was present in 9 percent of aide visits (314 of aides' 3,484 recent client visits) and that 25 percent of clients on oxygen therapy were described as smokers. Based on our findings, the Board of Health in a local town conducted a pilot study to address fire hazards related to medical oxygen. Medical oxygen combined with smoking or other sources of ignition is a serious fire and explosion hazard that threatens not only workers who visit homes but also communities.

Cleaning and disinfecting environmental surfaces in health care: Toward an integrated framework for infection and occupational illness prevention.

BACKGROUND: The Cleaning and Disinfecting in Healthcare Working Group of the National Institute for Occupational Safety and Health, National Occupational Research Agenda, is a collaboration of infection prevention and occupational health researchers and practitioners with the objective of providing a more integrated approach to effective environmental surface cleaning and disinfection (C&D) while protecting the respiratory health of health care personnel. METHODS: The Working Group, comprised of >40 members from 4 countries, reviewed current knowledge and identified knowledge gaps and future needs for research and practice. RESULTS: An integrated framework was developed to guide more comprehensive efforts to minimize harmful C&D exposures without reducing the effectiveness of infection prevention. Gaps in basic knowledge and practice that are barriers to an integrated approach were grouped in 2 broad areas related to the need for improved understanding of the (1) effectiveness of environmental surface C&D to reduce the incidence of infectious diseases and colonization in health care workers and patients and (2) adverse health impacts of C&D on health care workers and patients. Specific needs identified within each area relate to basic knowledge, improved selection and use of products and practices, effective hazard communication and training, and safer alternatives. CONCLUSION: A more integrated approach can support multidisciplinary teams with the capacity to maximize effective and safe C&D in health care.

Are green building features safe for preventive maintenance workers? Examining the evidence.

BACKGROUND: Many newly constructed green buildings (GB) are certified using the United States Green Building Council (USGBC) Leadership in Energy and Environmental Design (LEED) rating system for new construction and major renovation which focuses on architectural and mechanical design to conserve energy, reduce environmental harm, and enhance indoor quality for occupants. This study evaluated the preventive maintenance (PM) worker occupational safety and health (OSH) risks related to the design of GB. METHODS: PM job hazard analyses (JHA) were performed on the tasks required to operate and maintain five GB features selected from 13 LEED certified GB. A 22-item JHA and OSH risk scoring system were developed. RESULTS: Potentially serious OSH hazards included: green roofs made of slippery material without fall protection; energy recovery wheels and storm water harvesting systems in confined spaces; skylights without guard rails; and tight geothermal well mechanical rooms constraining safe preventive practices. CONCLUSIONS: GB can present PM OSH risks and these should be eliminated in the building design phase.

Determinants of exposure to 2-butoxyethanol from cleaning tasks: a quasi-experimental study.

BACKGROUND: The quantitative assessment of airborne cleaning exposures requires numerous measurement methods, which are costly and difficult to apply in the workplace. Exposure determinants can be used to predict exposures but have yet to be investigated for cleaning activities. We identified determinants of exposure to 2-butoxyethanol (2-BE), a known respiratory irritant and suspected human carcinogen, commonly found in cleaning products. In addition, we investigated whether 2-BE exposures can be predicted from exposure determinants and total volatile organic compounds (TVOCs) measured with direct reading methods, which are easier to apply in field investigations. METHODS: Exposure determinants were studied in a quasi-experimental study design. Cleaning tasks were performed similarly as in the workplace, but potential factors that can impact exposures were controlled. Simultaneously for each task, we measured concentrations of (1) 2-BE according to the National Institute for Occupational Health and Safety 1430 method and (2) TVOC with photoionization detectors (PIDs). Simple and multiple linear regression analyses were performed to identify 2-BE exposure determinants and to develop exposure prediction models. RESULTS: Significant determinants from univariate analyses consisted of product type, tasks performed, room volume, and ventilation. The best-fit multivariable model was the one comprised of product type, tasks performed, 2-BE product concentration, room volume, and ventilation (R(2) = 77%). We found a strong correlation between the 2-BE and the TVOC concentrations recorded by the PID instruments. A multivariable model with TVOC explained a significant portion of the 2-BE concentrations (R(2) = 72%) when product type and room ventilation were included in the model. CONCLUSIONS: Our results suggest that quantitative exposure assessment for an epidemiologic investigation of cleaning health effects may be feasible even without performing integrated sampling and analytic measurements.
