Sex Disparities in Ischemic Stroke Care: FL-PR CReSD Study (Florida-Puerto Rico Collaboration to Reduce Stroke Disparities)

Background And Purpose: Sex-specific disparities in stroke care including thrombolytic therapy and early hospital admission are reported. In a large registry of Florida and Puerto Rico hospitals participating in the Get With The Guidelines-Stroke program, we sought to determine sex-specific differences in ischemic stroke performance metrics and overall thrombolytic treatment.

Methods: Around 51 317 (49% women) patients were included from 73 sites from 2010 to 2014. Multivariable logistic regression with generalized estimating equations evaluated sex-specific differences in the prespecified Get With The Guidelines-Stroke metrics for defect-free care in ischemic stroke, adjusting for age, race-ethnicity, insurance status, hospital characteristics, individual risk factors, and the presenting stroke severity.

Results: As compared with men, women were older (73±15 versus 69±14 years; P<0.0001), more hypertensive (67% versus 63%, P<0.0001), and had more atrial fibrillation (19% versus 16%; P<0.0001). Defect-free care was slightly lower in women than in men (odds ratio, 0.96; 95% confidence interval, 0.93-1.00). Temporal trends in defect-free care improved substantially and similarly for men and women, with a 29% absolute improvement in women (P<0.0001) and 28% in men (P<0.0001), with P value of 0.13 for time-by-sex interaction. Women were less likely to receive thrombolysis (odds ratio, 0.92; 95% confidence interval, 0.86-0.99; P=0.02) and less likely to have a door-to-needle time <1 hour (odds ratio, 0.83; 95% confidence interval, 0.71-0.97; P=0.02) as compared with men.

Conclusions: Women received comparable stroke care to men in this registry as measured by prespecified Get With The Guidelines metrics. However, women less likely received thrombolysis and had door-to-needle time <1 hour, an observation that calls for the implementation of interventions to reduce sex disparity in these measures.
