Abstract

Background: Accreditation through the Intersocietal Accreditation Commission (IAC) is believed but not proven to increase quality in imaging. The goal of this study was to use quality metrics to evaluate the impact of accreditation on quality in pediatric echocardiography.

Methods: This is a retrospective study comparing quality metrics in 236 pediatric transthoracic echocardiograms in patients with congenital heart disease from (1) California Pacific Medical Center (CPMC), a community hospital, before and after IAC accreditation, and (2) the IAC-accredited Lucile Packard Children's Hospital (LPCH), an academic children's referral center, during equivalent eras. Consecutive patients who required cardiac intervention were matched between sites based on age, complexity, and time period. Two raters independently evaluated echocardiograms for image quality and study comprehensiveness. A third rater reviewed echocardiogram reports and medical charts for report completeness and diagnostic accuracy. Diagnostic error characterization was performed by consensus among the three raters. Report completeness was an IAC tool approved for maintenance of certification. The remaining quality metrics were developed by the American College of Cardiology Adult Congenital Pediatric Cardiology Quality Metrics Working Group initiative.

Results: At each site, 74 echocardiograms in the era before CPMC accreditation and 44 echocardiograms in the era after CPMC accreditation were included. There was no significant difference in image quality and diagnostic accuracy at CPMC before and after accreditation. Study comprehensiveness and report completeness improved at CPMC after accreditation (P < .001).

Conclusions: Accreditation through the IAC leads to increased study comprehensiveness and report completeness. Image quality and diagnostic accuracy did not differ significantly before and after IAC accreditation. We recommend further studies to assess the effects of accreditation on quality in echocardiography and patient outcomes.
