Stress Clinical Trial
— JOBSTRESS-OPHOfficial title:
Monitoring of JOB STRESS Related to Night Shifts in OPHthalmology Physicians and Residents
Ophthalmology physicians and residents work under stress conditions during night emergency ophthalmology shifts. Under time pressure, that is a characteristic of the urgency of care, they must use all their cognitive resources to make an accurate diagnosis and to provide accurate decisions, with sometimes surgical emergency acts. In addition, in France, they work at night following by an usual day work, and they can also work 48 consecutive hours during weekends, followed by a work day … i.e. 60 consecutive hours of work … Long working hours with a short recovery time has been demonstrated to be a major factor of stress and fatigue. Even if not demonstrated on ophthalmologists, those working conditions may contribute to symptoms of mental exhaustion and physical fatigue (sleep deprivation), often accompanied by a loss of motivation at work. This may leads to a feeling of loss of time control; stress can also distort the perception of time and leads to hasty actions or delayed decision-making. The combined effects of stress, feelings of loss of time control, and fatigue necessarily have an impact on work performance and work quality, with a high risk of medical error. Moreover, prolonged stress may expose ophthalmologists to a higher risk of multiple diseases, predominantly systemic inflammation and coronary heart disease. The main hypothesis is that prolonged work (up to 60 consecutive working hours) may impact on HRV, comparatively to a typical working day.
