Door-to-needle (DTN) is the duration between patient's arrival at the hospital and receiving intravenous thrombolysis in ischemic stroke settings, for which studies have reported delays in women. The "D's of stroke care" describes 8 steps (D1 to D8) in patients' time tracker. We implemented simple modifications to the "D's of stroke care" by splitting D4 and D6 steps into these substeps: patients' arrival to the emergency room (D4-A), early assessment by a neurologist (D4-B), neurologist decision on patient's eligibility to receive recombinant tissue plasminogen activator (D6-A), and patient's transfer to the stroke unit (D6-B). We evaluated the effect of these changes on reducing DTN time disparity between men and women. This study was conducted from September 2019 to August 2021, at a comprehensive stroke center. Patients were analyzed in 2 groups: group 1, before, and group 2, after using the modifications. Sex as the main variable of interest along with other covariates was regressed toward the DTN time. In groups 1 and 2, 47 and 56 patients received intravenous thrombolysis, respectively. Although there was a significant difference in DTN≤1 hour between women and men in group 1 (36% vs. 52%, P =0.019), it was not significantly different in group 2 ( P =0.97). Regression analysis showed being female was a significant predictor of DTN>1 hour in group 1 (adjusted odds ratio=6.65, P =0.02), whereas after using the modifications, sex was not a significant predictor for delayed DTN. Implementing these substeps reduced sex disparity in DTN time in our center.
