Abstract Sa707: The role of gender in conversations about suspected cardiac arrest with 9-1-1 callers and telecommunicators

Introduction: Women receive bystander cardiopulmonary resuscitation (BCPR) less frequently than men in public. Studies have demonstrated that the gender of the person calling 9-1-1 may influence receipt of BCPR for female patients with out-of-hospital cardiac arrests (OHCA). It is unknown how the tone, or the way a person speaks to someone else, and gender of the caller impact receipt of BCPR by gender of the patient. Objectives: We sought to understand whether the tone of the caller varies by gender of the caller and whether the tone impacts receipt of BCPR by gender of the patient. Methods: We performed a multiple methods retrospective analysis of 9-1-1 calls for suspected non-traumatic OHCAs in Durham, NC (08/2022-1/2024). Calls were professionally transcribed. We excluded pediatric arrests and those that occurred in a healthcare facility. We identified the gender of the caller and gender of the patient as well as receipt of BCPR. Using qualitative analysis, we coded a full range of tones through the transcripts and listening to the audio. Two team members double coded transcripts (AG, LH) and audio (LH, GW) until they reached interrater reliability. Theme matrix techniques were used to facilitate data analysis and presentation. Quantitative data were analyzed using descriptive statistics. Results: We included 170 total suspected OHCA calls. Mean age of patients was 56±20; 35% were women. Of these, 23% occurred in public and 50% received BCPR. When women called about women patients (16%), 50% received BCPR. When women called about men patients (42%), 51% received BCPR. When women were the callers, the primary tone was distressed (e.g., “Oh, my God. Give me one second, give me one second. I’m trying to think”) , independent of patient gender . When men called about women patients (19%), 50% of women patients received BCPR. In contrast, when men called about men patients (21%), 53% of men patients received BCPR. When the caller was a man, the primary tone was assertive (“Ma’am, she needs an ambulance!” ), independent of patient gender. Distressed or uncertain were also common tones for men callers (“I really rather a paramedic go up there and do that.”; "Yes, yes, please! I don’t have time to talk!"). Conclusion: Further research is needed to understand these interactions, including what types of interventions could improve equity and receipt of BCPR particularly for women.
