Background Adherence to widely accepted practice standards is a frequently used measure of healthcare quality. In the U.S., the most widely recognized authoritative source of practice standards for ethics consultation (EC) is the second edition of the American Society for Bioethics and Humanities’ Core Competencies for Healthcare Ethics Consultation report. Methods To determine the extent to which EC practices in U.S. hospitals adhere to these practice standards, we developed and analyzed 12 evaluative measures from a national survey. Results Only three of the 12 standards achieved over 75% adherence with reported EC practices: allowing anyone involved in a case to request an EC (100%), not requiring an attending physician’s permission to conduct an EC (97.6%), and having at least one person on the ethics consultation service (ECS) with advanced level EC proficiency (79.3%). Conclusions Implications are discussed for achieving consensus on EC standards as they continue to evolve.
