Improving Knowledge of Lactation Compatibility of Antirheumatic Medications Among Providers Who Care for Patients With Rheumatic Disease.

OBJECTIVE

We sought to evaluate and improve knowledge of lactation compatibility of medications commonly used to treat rheumatic diseases among rheumatology, obstetric, and newborn providers practicing at an academic safety net hospital.

METHODS

Baseline knowledge of rheumatic disease medication compatibility with lactation among 49 providers was obtained via a multiple-choice questionnaire. Following initial evaluation, providers were given a rheumatic diseases and lactation information card. The questionnaire was readministered at the time of card distribution and 5 months later.

RESULTS

At baseline, more rheumatology providers correctly identified a higher number of lactation-compatible and noncompatible medications than nonrheumatology providers (78% and 65% vs 31% and 46%, respectively; P < 0.0001). After the intervention, rheumatology providers correctly identified lactation-compatible and noncompatible medications 98% and 100% of the time, compared with 78% and 65% of the time before the intervention (P < 0.0001 and P < 0.0001). This improvement was durable because rheumatology providers correctly identified lactation-compatible and noncompatible medications 96% and 98% of the time 5 months following the initial intervention (P = 0.0021 and P < 0.0001). Nonrheumatology providers correctly identified lactation-compatible and noncompatible medications 31% and 46% of the time before the intervention and 95% and 100% of the time after the intervention (P < 0.0001 and P < 0.0001).

CONCLUSION

Rheumatology providers had better baseline knowledge than obstetric and newborn providers of the breastfeeding compatibility of medications used to treat rheumatic diseases. However, all providers had knowledge gaps. After a simple educational intervention, the knowledge gap was significantly narrowed in all provider groups. This improvement was durable because repeat testing of the rheumatology provider subset 5 months post intervention continued to show significant improvement.
