Abstract 9969: Are Men or Women More Likely to Call 911 During an Acute Coronary Syndrome (ACS)?
Introduction: Many patients with ACS fail to call 911. Several studies have identified gender differences in 911 use during an ACS. It may be that general health seeking behaviors impact differently on men and women, which may manifest as an increase in 911 calls. If present, the effect of general health seeking on gender differences in 911 use would be expected for both unstable angina (UA) and myocardial infarction (MI). To examine the effect of increased general health seeking behaviors, participants were stratified as either UA or MI in our examination of the association between gender and 911 use at ACS presentation.
Methods: Participants were hospitalized patients with an ACS (N = 476) enrolled in a prospective cohort study. Demographic, psychosocial and clinical factors were assessed within 7 days of enrollment via clinical interview or chart review. Calling 911 was determined by self-report and verified through a random selection of 20% of medical charts.
Results: Of the 476 participants, 292 (61.3%) had UA and 184 (38.7%) had an MI. Women and men with UA were equally likely to call 911 (14.9% vs. 12.6%, P = 0.59). In contrast, women with an MI were much more likely to call 911 than men (56.7% vs. 28.2%, P < 0.001). In a multivariable model adjusted for socio-demographic factors (age, race/ethnicity, public health insurance status, health insurance (within 2 years), high school education and martial status) and history of MI, women remained significantly more likely than men to call 911 during an MI (Prevalence Ratio 2.03; 95% C.I. 1.39 - 2.98, P < 0.001), Table.
Conclusion: Our study shows that women with an MI are two times as likely than men to call 911, independent of possible socio-demographic explanatory factors. Women with UA did not differ from men in calling 911. Our findings suggest that gender differences in calling 911 are unlikely to be related to either health seeking behaviors or socio-demographic factors.
