Aim: To determine the relationships among nurses' fatigue, nurses' performance and patient safety culture.
Design: Cross-sectional study.
Methods: A multicentre study was conducted with 308 nurses working in 14 medical and surgical wards from four teaching hospitals in Iran. The sampling method was stratified with a proportional allocation. Data were collected via a demographic form, the Occupational Fatigue/Exhaustion Recovery (OFER-15), the Nurse Performance Instrument (NPI) and the Hospital Survey on Patient Safety Culture (HSOPSC). The data were analysed via structural equation modelling (SEM).
Results: Nurse fatigue was significantly inversely related to performance and patient safety culture (p < 0.001). Path analysis revealed that each unit of reducing nurses' fatigue improved patients' safety culture by 0.286 units and that each unit of improved nurse performance improved patients' safety culture by 0.360 units. Additionally, each one-unit increase in a nurse's fatigue could decrease his or her performance by 0.860 units. SEM analysis confirmed the mediating effect of nurses' performance on the relationship between their level of fatigue and patient safety culture.
Practice Implications: The proposed model can assist nursing managers and healthcare policymakers in developing practical strategies to mitigate and reduce nurses' fatigue and, consequently, improve nurses' performance and patient safety.
Patient Or Public Contribution: All participants contributed to this research by completing self-reported scales.

Background: Preoperative biliary drainage (PBD) has been proposed as a strategy to manage the complications associated with biliary obstruction in hilar cholangiocarcinoma patients. However, the efficacy and safety of PBD in remain controversial, even in clinical guidelines. This meta-analysis aimed to provide a comprehensive evaluation of the efficacy and safety of PBD in patients with hilar cholangiocarcinoma.

Objectives: To profile the array of microbial contaminants of eye drops, both native and non-native to the ocular surface, and associated factors for contamination.
Methods: Potentially relevant studies were retrieved from major bibliographic databases (PubMed, Scopus, and Web of Science). Data were extracted, and study-specific estimates of the contamination rates of topical ophthalmic solutions were combined using meta-analysis to obtain pooled results.
