Congenital heart disease

Understanding gaps in guideline-recommended adult congenital heart disease care: Data from 12 US health care centers

Am Heart JPublished retrospective study

Authors' conclusion

Three-quarters of adults with CHD experienced gaps in specialized ACHD care while receiving services at high volume comprehensive tertiary health centers. To address these gaps, interventions such as fostering physician collaboration within tertiary centers might be needed, and targeted to patients with less severe CHD, nonphysiologic class conditions, and those aged 40+ years.

Study context

Population
Adults with congenital heart disease (CHD) receiving care at US health care centersCounted separately by period
Participants
18,934 vs 22,453
Exposure
Pre-COVID vs COVID
  • Pre-COVIDn = 18,934
  • COVIDn = 22,453
Outcome
1) Gaps in any adult congenital heart disease (ACHD) specialist visit and recommended testing throughout the study period. 2) Gaps in recommended ACHD follow-up care.
Methodological details12 centers in the national Patient-Centered Clinical Research Network, Pre-COVID (2015-2019) and COVID (2020-2022) periods analyzed separately
  • 12 centers in the national Patient-Centered Clinical Research Network
