Gender differences in the provision of key post-arrest interventions for out-of-hospital cardiac arrest (OHCA) patients—protocol for a systematic review

BACKGROUND: Evidence shows that the implementation of optimal post-arrest care significantly increases survival and functional outcomes among patients who experience an out-of-hospital cardiac arrest (OHCA). However, differences in OHCA survival have been reported between men and women, suggesting underlying differences in post-arrest care. This systematic review will evaluate gender differences in the provision of key post-arrest interventions. METHODS: Eligible studies will be identified through systematic searches of relevant databases. Randomized controlled trials and observational studies of adult patients will be eligible for inclusion if they report gender-specific data on the provision of one or more guideline-based post-arrest interventions in OHCA patients who survived to hospital admission. Two independent reviewers will perform both the title and abstract and full-text screening along with data abstraction for the selected studies. Study quality will be assessed using a modified Cochrane Risk of Bias tool for RCTs or the ROBINS-I tool for observational studies. The strength of evidence for each included study will be assessed using a modified Grades of Recommendation, Assessment, Development, and Evaluation (GRADE) system. DISCUSSION: To our knowledge, this systematic review will be the first to address the association between patient gender and the provision of post-arrest care. The findings from this systematic review will provide valuable insight to gender disparities in the provision of post-arrest care. This systematic review was designed in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. This protocol observes the Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols (PRISMA-P) statement.
