Quality in the Echo Lab

4 cards

Notes

Laboratory accreditation

  • IAC Echocardiography - primary accrediting body for adult TTE, TEE, stress echo, and adult congenital echo in the US.
  • Accreditation is often required by payers.

Personnel qualifications

  • Physicians: board-certified/board-eligible in cardiovascular disease or equivalent; specific echo training. National Board of Echocardiography (NBE) certification (ASCeXAM) is common.
  • Sonographers: registered by ARDMS or CCI in adult echo. Ongoing CME.

Volume requirements

  • Minimum annual case volumes for both physicians and sonographers to maintain proficiency.
  • IAC recommends specific minima that vary by testing area.

Quality assurance activities

  • Peer review of at least 10 % of studies - image quality, interpretation accuracy, report clarity.
  • Structured reporting - consistent format for measurements, findings, and conclusions.
  • Written protocols - standardized study performance for each type (TTE, TEE, stress, etc.).
  • CME - ongoing echo-specific education.

Reporting best practices

  • Preliminary vs final read distinction.
  • Comparison with prior study when applicable.
  • Report turnaround time metrics.
  • Impressions concise and clinically actionable.
  • Critical findings communicated directly to the ordering provider.

Equipment maintenance

  • Regular preventive maintenance.
  • Documentation of QA testing (image quality phantoms).
  • Transducer cleaning and disinfection between patients (per manufacturer and society guidelines).

Contrast use best practices

  • Sonographer training in contrast infusion.
  • Documentation of contrast administration.
  • Monitoring for adverse reactions.

Appropriate use criteria (AUC)

  • Society-defined criteria (ACC, ASE) to guide test ordering.
  • Reduces unnecessary imaging without compromising care.

Cards

  • basicVI.L-001
    Which organization accredits echocardiography labs in the United States?
    The IAC (Intersocietal Accreditation Commission) — specifically IAC Echocardiography.
  • basicVI.L-002
    Approximately what proportion of echo studies should undergo peer review as part of a quality-assurance program?
    At least 10% of studies periodically peer-reviewed for image quality, interpretation, and reporting.
  • basicVI.L-003
    Which credential is standard for a sonographer performing adult echocardiography in the US?
    Registered Diagnostic Cardiac Sonographer (RDCS) through the American Registry for Diagnostic Medical Sonography (ARDMS), or Registered Cardiac Sonographer (RCS) through Cardiovascular Credentialing International (CCI).
  • basicVI.L-004
    What are 'Appropriate Use Criteria' (AUC) in echocardiography?
    Society-endorsed (ACC, ASE) criteria that classify indications for echocardiography as appropriate, may be appropriate, or rarely appropriate — guiding test ordering to reduce unnecessary imaging.
