Factors influencing fatigue and its correlation with depressive symptoms, and their impact on turnover or transfer intentions: a retrospective study in an Okinawan ICU

This study found a correlation between ICU nurses' subjective fatigue and mental health, suggesting that severe fatigue, particularly due to interpersonal challenges, may be linked to TTI, highlighting the need for early interventions. However, no direct link was found between fatigue, depressive symptoms, and TTI. Further longitudinal research is required to clarify causality and enhance interventions. In rural areas such as Okinawa, where career options are limited, tailored interventions targeting fatigue and interpersonal challenges are essential.
