Night-Shift Work, Self-Reported Well-Being, and Perceived Patient Care Quality Among ICU Nurses: A Cross-Sectional Survey

Background/Aim: Night and rotating shift work are inherent to 24/7 intensive care units (ICUs), but they can disrupt circadian rhythms, affect sleep, and increase physiological and cognitive strain in nurses. This study aimed to describe the self-reported physical health, psychological well-being, job performance, and perceived patient-care quality of ICU nurses in relation to night-shift work. Methods: A descriptive, cross-sectional survey was conducted among ICU nurses recruited by convenience sampling from 10 tertiary hospitals. A researcher-developed structured questionnaire assessed demographic characteristics, physical health, psychological and emotional well-being, job performance, and perceived patient-care quality using a 12-month recall period for subjective health and patient safety items. Data were summarized using frequencies and percentages. Results: Among 123 ICU nurses (all participating in shift schedules encompassing night duties; 113 on active regular night shift rotations and 10 on rotating schedules with periodic night shifts), difficulty falling asleep was reported by 110 participants (89.4%). Occupational back injuries were reported by 70 participants (56.9%), while stress, mood changes, and interpersonal workplace conflict were reported by 59 (48.0%), 104 (84.6%), and 86 (69.9%) participants, respectively. Family conflict related to night-shift work was reported by 93 participants (75.6%). Nursing errors and missed care during night shifts were reported by 74 (60.2%) and 68 (55.3%) participants, respectively. These findings describe substantial self-reported health, psychosocial, and patient-care concerns among the study participants. Conclusion: The findings suggest that night-shift work is associated with self-reported sleep disruption, psychological strain, work-family conflict, and perceived patient-care risks among ICU nurses. Because the study used a cross-sectional design and self-reported measures, causal relationships cannot be established. Further studies using objective measures and longitudinal designs are warranted.
