Quality Indicator Completion Rates for Adults with Tetralogy of Fallot.

Quality indicators for adult congenital heart disease (ACHD) were recently published due to a lack of consensus regarding delivery of care to adults with congenital heart disease (CHD). The objective of this study was to examine adherence to quality indicators for the care of patients with tetralogy of Fallot. Adults with tetralogy of Fallot seen in outpatient cardiology clinics at a tertiary care facility between July 2014 and June 2015 were included, and electronic medical records for each visit were reviewed. Completion rates for eight proposed quality indicator metrics were recorded and results for ACHD and non-ACHD cardiologists were compared. A total of 96 eligible patients completed 179 cardiology visits (134 ACHD and 45 non-ACHD). The quality indicator completion rates were over 80% for 7 of the 8 indicators. Metric 5 (cardiac magnetic resonance imaging every five years) had the lowest completion rate at 38.7%. Compared to non-ACHD cardiologists, ACHD cardiologists had higher completion rates for QRS assessment (88.1% vs. 75.6%, p = 0.04), echocardiogram by CHD expert (97.8% vs. 80.0%, p < 0.001), and infective endocarditis counseling (95.9% vs. 77.4%, p = 0.001). In this single center study, there was a wide range of quality indicator completion rates for tetralogy of Fallot. Routine cardiac MRI by an expert in CHD was identified as an area for improvement. There were significant differences in quality indicator completion between ACHD and non-ACHD cardiologists.
