Abstract Objective  Hypertensive disorders of pregnancy (HDP) impact 10% of pregnancies in the United States and cause adverse maternal and neonatal outcomes such as prematurity and low birth weight. Aspirin administration to at-risk individuals during pregnancy can reduce risk of HDP. Study Design  Define-Measure-Assess-Improve-Control methodology was utilized to improve aspirin screening in an outpatient obstetric clinic. Retrospective cohort analysis compared outcome metrics pre- and postimplementation by using logistic regression models, adjusting for race and insurance. Key informant interviews and process mapping identified barriers to aspirin screening. A multidisciplinary team implemented low-cost strategies such as provider education, additional screening by ancillary staff, automated electronic reminders, and standardized patient counseling. Results  Over 6 months, the screening rate improved from 62.5 to 92.0% (adjusted odds ratio [aOR] = 6.89, 95% confidence interval [CI]: 3.30–14.43). The prescription rate for patients correctly identified to be eligible for aspirin improved from 66.7 to 82.4% (aOR = 1.96, 95% CI: 0.88–4.35). Conclusion  Comprehensive, tailored quality improvement efforts can significantly increase aspirin screening and prescription, which may decrease maternal and neonatal morbidity due to HDP. Key Points Initiative improved overall and correct screening rates. Initiative increased provider knowledge of eligibility. Low-cost interventions can have high impact over short time interval.
