Aim: To describe the progression of vigilance and sleepiness over the shift and the coping strategies of nurses working 12-hr day or night shifts.
Background: The spread of 12-hr shift work in nursing raises the question of whether sufficient vigilance can be maintained to ensure quality of care.
Method: 18 nurses working 12-hr shifts filled out a Karolinska Sleepiness Scale questionnaire and a Brief Psychomotor Vigilance Test, at the beginning of the shift and then every 3 hr. Coping strategies and quality of care were assessed on self-administered questionnaires, filled out at 3 hr, 6 hr, 9 hr and 12 hr after the start of the shift.
Results: The present investigation did not show significantly excessive sleepiness or vigilance impairment or poor self-perception of quality of work during 12-hr nursing work shifts, although Psychomotor Vigilance Test results gradually deteriorated slightly over duty time (from start to end of shift). Certain coping strategies were preferred such as 'having a nap' later in the night shift.
Conclusion: Attention needs to be paid to the health status of nurses working 12-hr shifts, with regular medical monitoring by the occupational health service.
Implications for nursing management: Coping strategies to maintain sufficient vigilance to ensure quality of care should be facilitated.
