Referral order placement decreases time to transfer to adult congenital heart disease care.

Abstract

Abstract Background Pediatric patients with moderate and great complexity congenital heart disease (CHD) may benefit from coordinated transfer to adult congenital heart disease (ACHD) centers to reduce the risk of complications; however, there are a variety of transfer practices. We examined the impact of referral order placement at the last pediatric cardiology visit on time to transfer to an ACHD center. Methods We analyzed data collected from pediatric patients with moderate and great complexity CHD who were eligible to transfer to our tertiary center’s accredited ACHD center. We examined transfer outcomes and time-to-transfer between those with a referral order placed at the last pediatric cardiology visit and those without using Cox proportional hazards modeling. Results The sample (n = 65) was 44.6% female and mean age at study start was 19.5 years (± 2.2). Referral orders were placed for 32.3% of patients at the last pediatric cardiology visit. Those who had a referral order placed at the last visit had significantly higher number of successful transfers to the ACHD center compared to those who did not (95% vs 25%, p < 0.001). In a Cox regression model, placement of a referral order at the last pediatric cardiology visit was associated significantly with a sooner time to transfer (HR 6.0; 95% CI 2.2–16.2, p > 0.001), adjusting for age, sex, complexity, living location, and pediatric cardiology visit location. Conclusions Placement of a referral order at the last pediatric cardiology visit may improve transfer occurrence and time to transfer to accredited ACHD centers.
