Improving Drug Exposure Knowledge During Lactation: Quality Improvement Initiative in Low-Income Women

Abstract

Objectives:

To improve maternal knowledge on medication and substance usage during lactation through prenatal breastfeeding education and assess breastfeeding rates at 2–4 and 6–8 weeks postpartum.

Study Design:

This quality improvement initiative occurred between August 2016 and October 2017. Pregnant women without contraindications to breastfeeding receiving prenatal care at one of four prenatal sites in Florida were eligible. Enrolled women participated in a 1-hour interactive session consisting of basic breastfeeding education and medication or substance use during lactation. Demographic information, medical history, and pre/post breastfeeding knowledge scores were obtained. Regression analysis was utilized to evaluate the influence of medication usage on breastfeeding rates at 2–4 and 6–8 weeks postpartum.

Results:

The majority of participants (N = 121; median age = 26) were Hispanic (64%), unmarried (70%), and unemployed (60%). Approximately 25% were on medications other than supplements. Of those, one-third reported concerns regarding medication usage and infant safety during lactation. Knowledge regarding postpartum medications or substances and their breastfeeding compatibility increased significantly postintervention; however, women who were using medications at 2–4 and 6–8 weeks postpartum were 4 times as likely to mix feed or formula feed as compared with mothers not taking medications (adjusted odds ratio [OR] at 2–4 weeks = 3.693 confidence interval [95% CI]: 1.398–9.757) and adjusted OR at 6–8 weeks = 4.208 (95% CI: 1.009–17.548).

Conclusions:

This prenatal breastfeeding education targeting low-income women improved knowledge on medication usage and lactation. However, despite increasing breastfeeding knowledge, medication use appears to influence infant feeding behaviors at 2–4 and 6–8 weeks postpartum.
