RESUMO
BACKGROUND: Previous studies conducted in North America, Europe, and East Asia (Liu et al., EClinicalMedicine 44:101293, 2022; Matsui et al., JAMA Netw Open 2:e195111, 2019; Awad et al., J Am Coll Emerg Physicians Open 4:e12957, 2023; Yoon et al., Prehosp Emerg Care :1-7, 2022) reported gender disparities in the provision of bystander CPR for patients with out-of-hospital cardiac arrest (OHCA). However, it remains unknown whether similar disparities exist in the Middle Eastern and Gulf regions. The primary objective of this study is to evaluate gender differences in the provision of bystander CPR for patients with OHCA in Qatar. METHODS: Retrospective analysis of data obtained from Hamad Medical Corporation OHCA registry in the State of Qatar (2016-2022). We included adults with non-traumatic and EMS-attended OHCA. We used multilevel logistic regression to examine the association between gender and provision of bystander CPR. RESULTS: In total, 4283 patients were included. Of those, 3414 (79.7%) were males, 1639 (38.3%) arrested in public locations, and 1463 (34.2%) received bystander CPR. Unadjusted comparisons showed that females were significantly older than males (mean age: 62.2 vs. 52.7). Females had a lower proportion of OHCA occurring in public locations (15.1% vs. 44.2%) and a lower proportion of shockable rhythm (11.9 vs. 27.5%). Regarding the outcome variable (provision of bystander CPR), the unadjusted analysis showed that the proportion of females who received bystander CPR was lower than that of males (29.2% vs. 35.4%, p < 0.001). However, after adjustment, we found no significant difference in provision of bystander CPR by gender (adjusted OR female vs. male 0.99, 95% CI 0.84-1.20, p = 0.97). In the subgroup who arrested in public locations, the analysis revealed females had greater odds of receiving bystander CPR (adjusted OR female vs. male 1.47, 95% CI 1.10-1.82, p = 0.04). CONCLUSIONS: Overall, bystander CPR was less common in female gender; after adjustment for other covariates, including arrest location, we found no significant gender differences in provision of bystander CPR. We also observed that females were found to have a lower incidence of cardiac arrest in public locations. Nevertheless, if females were to experience cardiac arrest in a public location, they would be more likely to receive CPR. Further research is required to explain the observed differences in provision of bystander CPR.
RESUMO
A comprehensive review of medical examiner data was undertaken of all hanging deaths in the Canadian Maritime province of Newfoundland and Labrador from 1982 to 2021. A total of 811 cases were identified representing suicidal, accidental, and undetermined manners of death. Variables examined included age; sex; seasonality; ligature type; location; time since death; prior attempts/suicidal ideation; presence/absence of a suicide note; and presence/absence of alcohol and drugs. Data subsets were generated, and additional analysis was conducted for hangings involving females; suicidal hangings occurring in the region of Labrador; and those who hanged themselves outdoors. Results indicate that females are choosing to kill themselves by hanging in rapidly increasing numbers. Outdoor suicides by hanging were more common in Newfoundland and Labrador (22.1%) than previously reported in Alberta (11.5%), Texas (5%), and Turkey (12-13%). Unique trends in seasonality were revealed, as were repeated incidents of suicidal clusters. The age distribution was skewed strongly toward youths (10 to 22 years of age), particularly in Labrador. Although Labrador represents only 5% of the total provincial population, it produced 20.1% of the total suicidal hangings in the study. The suicide rate in Canada has decreased by 24% over the past 40 years, yet the rates of suicidal hangings nationally and in Newfoundland and Labrador have increased during the same time period. With a better understanding of the circumstances under which people commit suicide by hanging within the province, it may be possible to target at-risk groups to prevent future cases.
