RISKS IN THE VISUAL ENVIRONMENT SUCH AS GLARE, ILLUMINANCE AND LUMINANCE RATIO - RISK ASSESSMENTS MADE WITH VISUAL ERGONOMICS RISK ASSESSMENT METHOD, VERAM– A DESCRIPTIVE PAPER

The visual environment has an impact on subjective strain and headaches. A visual ergonomics risk assessment method, VERAM, was used on 217 workplaces, and consists of both of a subjective questionnaire and an objective risk assessment, the latter risks are presented in this paper. The risk for daylight was assessed to be yellow (moderate risk) or red (high risk) at 53% of the workplaces and the risk for glare was yellow or red at 66%. The assessment of the lighting design showed a yellow or red risk at 44% of the workplaces and the illuminance was assessed to be insufficient at 49% of the workplaces. Flicker or TLM (temporal light modulation) was assessed to be a problem among 33%. These results show that the design of the visual environment is in most cases not performed in a satisfying way. The visual environment is essential to increase wellbeing, health and performance.

Subjective strain of care experienced by pulmonary and critical care medical nurses when caring for patients with delirium: a cross-sectional study

Background Delirium, a disorder of consciousness, often occurs for a period of time during hospitalisation. It is characterised by a disturbance of attention or awareness. Hyperactive delirium may lead to accidental removal of medical equipment, while hypoactive delirium may inhibit patients from participating in nursing interventions, medical treatment, and physical therapy. However, there are limited relevant studies of the strain of care of nurses in China when caring for patients with delirium. This study, thus, aimed to investigate the subjective level of the strain of care experienced by pulmonary and critical care nurses when caring for patients with delirium. Methods This was a descriptive, cross-sectional study. A survey was conducted with 100 nurses in the Chinese pulmonary and critical care medical (PCCM) department in 2018. The Strain of Care for Delirium Index (SCDI) was used to measure nurses’ strain of care. Participants were instructed to rate the degree of perceived difficulty in managing patients who displayed the behaviours listed in the SCDI, on a scale from 1 (quite easy) to 4 (very difficult). The mean ± standard deviation (SD) scores of the ranked difficulty scores were calculated. Results In our sample, 47 % of the nurses had received delirium-related training previously. The three wards with the highest strain of care scores when caring for patients with delirium were the chronic obstructive pulmonary disease ward (3.29 ± 0.72), interstitial lung disease ward (3.11 ± 1.31), and respiratory intensive care unit (3.02 ± 0.78). The three types of patient behaviours associated with the highest degree of nursing strain of care were being uncooperative and difficult to manage (3.37 ± 0.84), pulling out tubes and tearing out dressings (3.33 ± 0.98), and irritability (3.22 ± 0.95). Conclusions This study is the first to focus on nurses’ subjective strain of care when caring for patients with delirium in PCCM departments in China. The findings suggest the need to pay more attention to the working status of Chinese nurses. Further trials with large samples assessing relevant outcomes of patients with delirium are warranted.

Predicting Caregiver Strain to Improve Supports for the Caregivers of Children With Emotional and Behavioral Disorders

Caregivers of children/youth with emotional and behavioral disorders often can experience significant strain associated with the day-to-day care of their children, and reducing strain can bring tremendous advantages to children, caregivers, and families. This study examines several predictors of caregiver strain hypothesized to be related to caring for children with emotional and behavioral disorders. Specifically, children’s symptoms, child and caregiver demographics, caregiver mental health, and caregiver relationship to child were examined to better understand both objective and subjective strain among a sample of families participating in a system of care in southeast Indiana. Regression analyses demonstrated that children’s externalizing symptoms are the strongest predictor for both objective strain and subjective strain. Moreover, caregivers who had experienced mental health issues reported higher levels of subjective externalized strain; biological parents tend to experience higher subjective internalized strain than other relative caregivers do. Implications for practitioners, caregivers, and future research are also discussed.
