Evaluating Home Healthcare Workers' Safety Hazard Detection Ability Using Virtual Simulation

Effects of virtual heights, dual-tasking, and training on static postural stability

Working at altitudes, dual-tasking (DT), and lack of experience cause falls. This study aimed to investigate the impact of virtual heights, DT, and training on static postural stability. Twenty-eight volunteers' balance at seven virtual environments [VE; ground (G), altitude 1 (A1), edge 1 (E1), altitude 2 (A2), edge 2 (E2), altitude 3 (A3), and edge 3 (E3)] were recorded during single-tasking (ST) and DT over three days. Independent variables were analyzed using a 7 (VE) x 3 (DAY) x 2 (TASK) factorial repeated measures ANOVA. Greater postural sway was observed in A3 and E1, on DAY 1, and during DT. The study demonstrated static postural stability deteriorates at higher virtual altitudes and during DT and improves with training. The findings of the study suggest that virtual reality is a great altitude simulator, which could be used as a potential balance training tool in ergonomic settings.

Physiological and Subjective Measures of Anxiety with Repeated Exposure to Virtual Construction Sites at Different Heights

Background

Occupational workers at altitudes are more prone to falls, leading to catastrophic outcomes. Acrophobia, height-related anxiety, and affected executive functions lead to postural instabilities, causing falls. This study investigated the effects of repeated virtual height exposure and training on cognitive processing and height-related anxiety.

Methods

Twenty-eight healthy volunteers (age 20.48 ± 1.26 years; mass 69.52 ± 13.78 kg) were recruited and tested in seven virtual environments (VE) [ground (G), 2-story altitude (A1), 2-story edge (E1), 4-story altitude (A2), 4-story edge (E2), 6-story altitude (A3), and 6-story edge (E3)] over three days. At each VE, participants identified occupational hazards present in the VE and completed an Attitude Towards Heights Questionnaire (ATHQ) and a modified State-Trait Anxiety Inventory Questionnaire (mSTAIQ). The number of hazards identified and the ATHQ and mSTAIQ scores were analyzed using a 7 (VE; G, A1, A2, A3, E1, E2, E3) x 3 (DAY; DAY 1, DAY 2, DAY 3) factorial repeated measures analysis of variance.

Results

The participants identified the lowest number of hazards at A3 and E3 VEs and on DAY 1 compared to other VEs and DAYs. ATHQ scores were lowest at G, A1, and E1 VEs.

Conclusion

Cognitive processing is negatively affected by virtual altitudes, while it improves with short-term training. The features of virtual reality, such as higher involvement, engagement, and reliability, make it a better training tool to be considered in ergonomic settings. The findings of this study will provide insights into cognitive dual-tasking at altitude and its challenges, which will aid in minimizing occupational falls.

Safety Concerns Associated with Home Care Nursing

Compared to nurses in acute care settings, home care nurses face unique threats to safety, including unsanitary conditions in homes, dangerous pets, firearms in the home, hostile patients or family members, high-crime neighborhoods, and motor vehicle accidents while traveling between patients. The purpose of this descriptive study was to explore specific personal safety and environmental concerns faced by home care nurses. Seventy-five home care and home hospice nurses completed an anonymous Qualtrics survey. Seventy-eight percent admitted to feeling unsafe during a home visit. Safety threats included unsafe neighborhoods, aggressive dogs, aggressive or drug-seeking family members, patients with mental health concerns, sexual harassment, and most alarmingly feeling threatened by a firearm. Participants also identified environmental concerns such as secondhand smoke and bedbugs, and a high number of musculoskeletal injuries they perceived to be related to their work in home care. Home care is a rapidly growing industry with a critical need to attract and retain workers. Safety training specific to the workers' role should be offered at the time of hire and annually thereafter. Home care nurses should be aware of threats to safety and employ the strategies of preparation, awareness, alertness, and prevention before and during visits.

Home health aides' experiences of their occupational health: a qualitative meta-synthesis

Home health aides (HHA) have high sickness absence while the need for home care services is rapidly growing. The aim of this study was to derive new conceptual understandings by identifying, describing and interpreting key concepts across qualitative studies on how HHA experience their occupational health related to their working conditions.A qualitative ethnographic meta-synthesis was used as a method to analyze 27 articles included from systematic searches in CINAHL, MEDLINE and PsycINFO.HHA experience physical strenuous work task demands in combination with unfortunate organizational conditions in an uncontrolled and ever-changing psychosocial and physical working environment as the main obstacle to their occupational health, although many positive presence factors with opposite effects were reported.More research is needed to investigate whether physical demanding work tasks can have positive effects on HHA's occupational health by reorganizing their work while preserving patients' empowerment at their home.
