Clinical Report: The Association Between Shift Work and Hospital-Treated Infections
Overview
This study investigates the link between shift work and the incidence of hospital-treated infections, revealing a significant association. It also explores the mediating role of lifestyle factors such as smoking and sleep duration in this relationship.
Background
Shift work is increasingly common in modern economies, yet it poses potential health risks, including chronic diseases and infections. Understanding the impact of shift work on infection susceptibility is crucial, especially in light of the COVID-19 pandemic, which has highlighted vulnerable populations. This study aims to fill gaps in existing research by focusing on hospital-treated infections, which have greater implications for healthcare.

266,450
Median Follow-Up
12.5 years
Adjusted HR for Hospital-Treated Infections
1.10 (95% CI 1.07–1.13)
Key Findings
Shift work is associated with a higher risk of hospital-treated infections.
Excess risks were noted for lower respiratory, gastrointestinal, genitourinary, and skin/soft-tissue infections.
Mediation analyses indicated contributions from smoking, unhealthy sleep duration, sedentary behavior, alcohol use, and higher BMI.
Risk gradients were similar across different frequencies of shift work.
Healthcare and service occupations showed higher infection risks compared to manufacturing or construction.
Clinical Implications
Healthcare professionals should consider shift work as a potential occupational hazard that may elevate infection susceptibility. Implementing preventive measures targeting modifiable lifestyle factors could mitigate these risks for shift workers.
Conclusion
The findings underscore the need for targeted health interventions for shift workers to reduce their risk of hospital-treated infections. Addressing lifestyle factors may enhance the health outcomes of this population.
