ABTS Critical Care Policy

The American Board of Thoracic Surgery considers it inappropriate to exclude its Diplomates from credentialing for care of thoracic surgical patients in a critical care setting based on the Diplomate's training or board certification. Our Diplomates have been trained in critical care management of thoracic surgical patients and they have successfully completed both written and oral examinations, which cover the critical care aspects of the thoracic surgical patients.
