RESUMEN
This scoping review collates evidence for sex biases in the receipt of bystander cardiopulmonary resuscitation (BCPR) among patients with out-of-hospital cardiac arrest patients globally. The MEDLINE, PsycINFO, CENTRAL, and Embase databases were screened for relevant literature, dated from inception to March 9, 2022. Studies evaluating the association between BCPR and sex/gender in patients with out-of-hospital cardiac arrest, except for pediatric populations and cardiac arrest cases with traumatic cause, were included. The review included 80 articles on BCPR in men and women globally; 58 of these studies evaluated sex differences in BCPR outcomes. Fifty-nine percent of the relevant studies (34/58) indicated that women are less likely recipients of BCPR, 36% (21/58) observed no significant sex differences, and 5% (3/58) reported that women are more likely to receive BCPR. In other studies, women were found to be less likely to receive BCPR in public but equally or more likely to receive BCPR in residential settings. The general reluctance to perform BCPR on women in the Western countries was attributed to perceived frailty of women, chest exposure, pregnancy, gender stereotypes, oversexualization of women's bodies, and belief that women are unlikely to experience a cardiac arrest. Most studies worldwide indicated that women were less likely to receive BCPR than men. Further research from non-Western countries is needed to understand the impact of cultural and socioeconomic settings on such biases and design customized interventions accordingly.
