Background: Shift workers have worse health outcomes than employees who work standard business hours. However, it is unclear how this poorer health shift may be related to employee work productivity.
Objective: The purpose of this systematic review is to assess the relationship between shift work and errors and performance.
Methods: Searches of MEDLINE/PubMed, EBSCOhost, and CINAHL were conducted to identify articles that examined the relationship between shift work, errors, quality, productivity, and performance. All articles were assessed for study quality.
Results: A total of 435 abstracts were screened with 13 meeting inclusion criteria. Eight studies were rated to be of strong, methodological quality. Nine studies demonstrated a positive relationship that night shift workers committed more errors and had decreased performance.
Conclusions: Night shift workers have worse health that may contribute to errors and decreased performance in the workplace.
Keywords: After-hours; efficiency; productivity; safety.
