Abstract

BACKGROUND: Sex-based disparities in acute coronary syndrome (ACS) presentations exist and women often have worse outcomes after an ACS event. Calling the emergency medical services (EMS) initiates prehospital diagnosis and treatment and reduces in-hospital time to treatment. This study aims to identify factors affecting the intention to call EMS and EMS usage in Australian women and men. METHODS: A retrospective cross-sectional analysis was conducted to identify sex differences and associated characteristics in the (1) intention to call EMS and (2) EMS use in the setting of ACS. Data sources included national survey data (2018-2020) and the Victorian Emergency Minimum Dataset (2016-2021). Multivariable analysis identified factors associated with intention and EMS use by sex. RESULTS: Of 34 328 survey participants, fewer men expressed an intention to call EMS if experiencing ACS symptoms than women (62.7% vs 70.4%, p<0.001). Associated factors in men included being of Aboriginal or Torres Strait Islander origin, living in Western Australia, having diabetes or having a lower education level. In both sexes, preferring a non-English language, having cardiovascular risk factors, poor symptom knowledge, living in the Northern territory or no/unclear EMS insurance status were associated with lower intentions to call EMS. Finally, women were less comfortable with calling EMS and more likely to hesitate (69.1 vs 76.7%, p<0.001).Among 51 165 ACS presentations (33.6% women) to Victorian public hospitals, fewer men presented by EMS (62.5% vs 67.7%, p<0.001), however, no associated male-specific characteristics were identified. Women preferring a non-English language or living in outer regional/remote Victoria were less likely to use EMS. Being born overseas or being referral by a healthcare provider was associated with lower EMS use in both sexes. CONCLUSION: Sex differences were identified in the intention and use of EMS during an ACS event based on cultural background, preferred language and residential regionality. These subgroups' characteristics can be targeted with education to improve EMS use.
