A comparison of rotating-shift and permanent night nurses

Area of Science:

• Nursing
• Chronobiology
• Occupational Health

Background:

• Shift work, particularly night shifts, poses challenges to nurses' well-being and performance.
• Permanent night nurses are hypothesized to adapt better than rotating shift nurses.
• Understanding adaptation mechanisms is crucial for optimizing shift work schedules.

Purpose of the Study:

• To test if permanent night nurses are subjectively better off than rotating shift nurses on their first night of duty.
• To investigate the underlying reasons for any observed differences, focusing on biological rhythm adjustment versus lifestyle factors.

Main Methods:

• A comparative study involving 30 permanent and 30 rotating shift female nurses.
• Data collection included sleep diaries, oral temperature measurements, and subjective ratings of well-being and work effort.
• Analysis focused on differences in sleep patterns, temperature rhythms, and subjective experiences.

Main Results:

• Permanent night nurses reported significantly better subjective well-being than rotating shift nurses.
• No significant differences were found in the magnitude of the temperature drop between midnight and 4 a.m. between the groups.
• Differences in subjective ratings were not attributed to maintained nocturnal orientation but rather to pre-shift sleep duration and potentially lifestyle/social factors.

Conclusions:

• Permanent night nurses' superior subjective well-being is unlikely due to better biological rhythm adjustment.
• Lifestyle and social differences between permanent and rotating night nurses may play a more significant role in their perceived well-being.
• Further research should explore these non-biological factors in shift work adaptation.
