Shift-Work Scheduling and Health Outcomes in Emergency Dispatchers and Safety-Critical Occupations: A Scoping Review

Public safety telecommunicators sustain 24/7 operations through nonstandard, rotating schedules that may affect health and performance, yet scheduling research specific to emergency communications centers remains limited. We aimed to examine how shift-work structure or scheduling characteristics may contribute to occupational performance, physical health, psychological health, and social and family functioning outcomes in emergency dispatchers and comparable 24/7 safety-critical occupations, identifying risks, practical considerations, and priority research gaps. We searched PubMed, PsycINFO, CINAHL, Web of Science, and Scopus for primary studies published January 2000–May 2026. We included studies examining associations among five scheduling exposure domains (shift timing and duration; rotation and circadian disruption; recovery and schedule spacing; predictability and control; and overtime and interventions) and outcomes spanning occupational performance, physical and psychological health, health behaviors, and social functioning. The search yielded 5259 studies; 66 met the inclusion criteria and were largely observational. Three studies examined dispatcher populations, with no dispatcher-specific evidence for three exposure domains. The most consistent cross-occupational signal linked night work and extended shifts to impaired sleep and cognitive performance. Comparator evidence indicated that schedule architecture and schedule control or mandatory overtime were associated with outcomes independent of shift length. This persistent evidence gap concerns a workforce facing continuous coverage demands, high cognitive load, and trauma exposure. Available evidence supports reframing center schedules as occupational health exposures and prioritizing high-quality (e.g., longitudinal, intervention-based) dispatcher research.
