Accreditation, Credentialing, and Quality Improvement in Diagnostic Medical Sonography: A Literature Review

Abstract

There are few regulations regarding facility accreditation and individual credentialing in diagnostic medical sonography (DMS), although it is known that the quality of examinations in the field can vary based by the operator. This literature review summarizes the findings from 19 research studies on accreditation, credentialing, and quality improvement and includes illustrative quotes from 23 position papers and 42 editorials. The review uncovered large differences in facility accreditation status based on sonography specialty and geographical area. The findings included many examples of positive correlations between accreditation and improved quality and also a positive correlation between credentialing and improved image quality. The survey studies revealed overwhelming support for accreditation and credentialing. Many articles raised concerns about the unknown quality of sonograms performed in nonaccredited facilities or by uncredentialed sonographers. If facility accreditation and/or individual credentialing could be implemented nationwide in DMS, it may lead to increased quality within the field.
