Quality Improvement Initiative for Aspirin Screening and Prescription Rates for Preeclampsia Prevention in an Outpatient Obstetric Clinic.

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..
