Development of a High-Performing Congenital Heart Program in Vietnam

Objective Children's HeartLink and the University of California San Francisco (UCSF) have partnered with Vietnam National Children's Hospital (VNCH). Compared with low- and middle-income countries (LMICs) enrolled in the International Quality Improvement Collaborative for Congenital Heart Disease, VNCH is a high performing center. Our goal is to compare outcomes of VNCH with North American centers leveraging data from the Pediatric Cardiac Critical Care Consortium (PC 4 ) in 2023. Methods Children's HeartLink established a partnership with VNCH in 2017 with a consistent senior-level medical volunteer team from UCSF (Dr Sano currently at Showa University Hospital) engaged in semiannual training visits and weekly case conferences. In-person visits have evolved to hands-off teaching. Areas of improvement are identified, and outcomes presented at the subsequent visit. International Quality Improvement Collaborative and PC 4 perform site specific audits to confirm data accuracy. Data presented are based on primary operations. Conversion from Risk Adjustment for Congenital Heart Surgery (RACHS-1) to STAT is as follows: RACHS-1 1-4 equal STAT 1-4; RACHS-1 5-6 equal STAT 5. Results Results represent 8 on-site visits and 109 case discussions. VNCH performed 1,056 operations, and PC 4 represents 14,506 operations in 2023. VNCH had comparable outcomes, except higher surgical mortality for infants with prematurity and noncardiac abnormalities, and a higher rate of surgical site infections. VNCH performed fewer operations on patients with noncardiac abnormalities and higher STAT scores. Conclusions Partnership of highly resourced North American programs with underresourced LMIC centers can elevate congenital heart surgery outcomes. VNCH is a high-volume center with respectable outcomes. Future focus will be higher STAT level and neonatal surgeries.
