“…Such findings are supported by controlled circadian laboratory studies on alertness, vigilance, sleepiness, and fatigue, which show a clear 24-h variation in these parameters (Åkerstedt, 2007;Aschoff, 1965;Cajochen et al, 1999;Dijk et al, 1992;Graw et al, 2004) and deterioration in these parameters after sleep deprivation (Axelsson et al, 2008;Dinges et al, 1997;Doran et al, 2001;Franzen et al, 2008;Sallinen et al, 2008;Van Dongen et al, 2003). We investigated the incidence rate in rotating shift workers (undertaking morning, late, and night shifts) employed in two different shift-work rotations (Kantermann et al, 2012b). A retrospective analysis of the incidence data from 730 male shift workers employed in either a CW (e.g., rotating from the morning shift to the late shift to the night shift) or CC rotation (e.g., rotating from the night shift to the late shift to the morning shift) with comparable work conditions at the same steel factory over a 5-year period has been performed.…”

“…Starting early particularly increased the risk (p<0.001), so that the peak was during the fourth hour of the shift [34]. In the Belgian metal factory (n=730 male shift-workers), the higher accident rate was found in the morning shift compared to the late shift or to the night shift (p<0.01) [35].…”

Abstract:The aim of this review is to examine the effect of extended working hours and shift work on occupational injuries. A calculation based on five studies shows that the risk of occupational injury during afternoon shifts was 6% lower than that during morning shifts. The same kind of calculation showed that the risk of occupational injury during night shifts was 15% lower than during morning shifts. A review of twelve studies showed that the risk of occupational injury was 15% higher for 10-hour working days compared to 8-hour working days. On the other hand, working 12-hour days increased the risk of occupational injury by 38%. When working more than 12 hours per day, four studies showed a 147% increase in involvement in occupational injury. The results of this review showed that shift work considerably increased the risk of occupational injury in the USA, but not in India and Singapore. Extended working hours was related to elevated risk of occupational injury. Thus shift work and long work hours did not suit for all employees.

“…[6][7][8] However, no evidence of change or increased sleep quality and length during the day as a result of the change to forward rotation has been provided thus far. [9][10][11][12][13] Similarly, no difference in self-rated sleep, [14][15][16] alertness during the shift, 16 or driving performance 15,17 were observed when comparing workers following forward and backward rotation schedules.…”

IMPORTANCEThe association of fast backward-rotating shift work (ie, anticlockwise sequence of afternoon, morning, and night shifts) with subjective and objective measures of sleep-wake quality, daytime attention, and tiredness of health care workers has not yet been established. OBJECTIVE To investigate the association of shift rotation direction with tiredness, sleepiness, and sustained attention among nurses working forward-and backward-rotating shifts. DESIGN, SETTING, AND PARTICIPANTS Data of this cohort study were collected from nurses working at 5 midsized Italian hospitals. The nurses had either a forward-rotating schedule (ie, morning to afternoon to night) and or a backward-rotating schedule (ie, afternoon to morning to night). The data were collected from July 2017 to February 2020. Data analysis was performed from May to October 2020. EXPOSURES Participants were working either forward-or backward-rotating schedules, in which the sequence of 3 shifts (morning, afternoon, and night) changed in a clockwise or anticlockwise direction. MAIN OUTCOMES AND MEASURES Sleep data were collected using the Karolinska Sleepiness Scale and Pittsburgh Sleep Quality Index. Sustained attention was measured using the Psychomotor Vigilance Task. Tiredness was evaluated using the Tiredness Symptom Scale. RESULTS A total of 144 nurses (mean [SE] age, 41.3 [0.8] years; 92 women [63.9%]) participated in the study; 80 nurses had forward-rotating schedules, and 64 had backward-rotating schedules.Nurses with irregular sleep-wake patterns due to night shift work had poor sleep quality (46 [57.5%] in forward-rotating schedule group; 37 [57.8%] in backward-rotating schedule group). Nurses working backward-rotating shifts exhibited significantly greater sleepiness (F 1,139 = 41.23; P < .001) and cognitive slowing (ie, longer median reaction times; F 1,139 = 42.12; P < .001) than those working forward rotations. Importantly, these differences were not affected by age, years of employment, and quality of sleep. Of nurses working on a backward-rotating schedule, 60 (93.8%) reported elevated sleepiness (Karolinska Sleepiness Scale score Ն7) after the night shift. The median reaction time (F 1,139 = 42.12; P < .001), 10% fastest reaction time (F 1,139 = 97.07; P < .001), minor lapses (F 1,139 = 46.29; P < .001), and reaction time distribution (F 1,139 = 60.13; P < .001) of nurses on backward-rotating schedules indicated a lower level of vigilance, which is negatively associated with neurobehavioral performance. CONCLUSIONS AND RELEVANCEIn this study, both shift rotation models were negatively associated with health and cognitive performance. These findings suggest that forward shift rotation may be more beneficial than backward rotation for several measured performance attentional (continued) Key Points Question Among hospital staff who work day and night shifts, do sleep and attention metrics vary between those who work forward-vs backwardrotating shifts? Findings This cohort study of 144 nurses found that fast forward-rotating shifts...
