This study utilized a two-wave multilevel panel study design with a 4-month interval, involving 379 participants across 23 critical care units in Malaysian hospitals. Grounded in the Conservation of Resources theory, we examined how job demands (i.e., workload, emotional demands, and job complexity) influence IPC practices and how three types of safety climate constructs-safety climate, psychosocial safety climate, and psychological climate-moderate the effects of job demands on IPC. Contrary to our predictions, none of the job demands were directly associated with IPC practices. However, we found that only the safety climate moderated the relationships between workload and job complexity with IPC practices. These findings suggest that each type of safety climate uniquely buffers the effects of specific job demands on IPC practices.

This retrospective cross-sectional study evaluated whether routinely collected physiological indicators could support exploratory stratification of positive TMT responses within a treadmill prioritization (TP) framework. Occupational surveillance records were analyzed among rotational shift workers in the Indonesian oil and gas industry between January 2024 and December 2025. Universal TMT was performed in 3,631 workers (3,544 male, 87 female), with 40 positive TMT responses. Associations were evaluated using multivariable Firth logistic regression, and a reduced exploratory model including hemoglobin and estimated glomerular filtration rate (eGFR) was internally validated using bootstrapping. Higher hemoglobin was independently associated with lower odds of positive TMT response (adjusted OR 0.73; 95% CI 0.58-0.94). The reduced framework demonstrated moderate discrimination (optimism-corrected AUC 0.72) and visual calibration agreement. Within the derivation cohort, 409 workers (11.3%) were classified as low-risk, with no observed positive TMT responses.

Respondents (n=294) rated their estimated likelihood of experiencing five major types of occupational accidents across six levels of injury severity. The results indicated that the FSL risk was not consistently underestimated relative to other accident types. However, when the subjective risk was compared with the objective accident frequency, the non-fatal FSL risk was systematically underestimated, whereas the fatal FSL risk was overestimated. Perceived risk of leaving work for more than 3 months due to non-fatal occupational accidents also decreased with age across accident types, with younger workers reporting the highest estimates and older workers the lowest.
