Guidelines recommend lifelong care with adult congenital heart disease (ACHD) specialists for adults with congenital heart disease (CHD). However, such gaps in visits at specialized ACHD centers have not been well-characterized from diverse US settings. This retrospective study analyzed data from 12 centers in the national Patient-Centered Clinical Research Network. CHD conditions were classified using International Classification of Disease codes and a hierarchical algorithm. ACHD specialists were identified by investigators and encounter volumes. Data from the 'Pre-COVID' (2015-2019) and 'COVID' (2020-2022) periods were analyzed separately. Main outcome measures were: 1) Gaps in any ACHD specialist visit and recommended testing throughout the study period. 2) Gaps in recommended ACHD follow-up care. During pre-COVID (N=18,934) and COVID (N=22,453) periods, between 55.3%-55.8% were males, 27.2%-31.0% were 40+ years, 18.2%-19.6% had severe CHD, and 52.7-55.0% had CHD physiologic class B-D conditions. Between 47.0%-54.5% had gaps in specialist visit and 13.0%-24.6% had gaps in all the testing. Patients with gaps in specialist visits were 6.33-9.44 times more likely to have gaps in testing. Gaps were more common among patients with moderate (adjusted odds ratio AOR: 2.61) and simple (AOR: 2.84) CHD, those aged 40+ (AOR: 1.53) and non-physiologic class conditions (AOR 1.51). In both periods, 64.1%-71.5% of patients had gaps in follow-up care. 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, non-physiologic class conditions, and those aged 40+ years.
