Introduction Clinical ethics committees (CECs) support and enhance communication and complex decision making, educate healthcare professionals and the public on ethical matters and maintain standards of care. However, a consistent approach to training members of CECs is lacking. A systematic scoping review was conducted to evaluate prevailing CEC training curricula to guide the design of an evidence-based approach.

Methods Arksey and O’Malley’s methodological framework for conducting scoping reviews was used to evaluate prevailing accounts of CEC training published in six databases. Braun and Clarke’s thematic analysis approach was adopted to thematically analyse data across different healthcare and educational settings.

Results 7370 abstracts were identified, 92 full-text articles were reviewed and 55 articles were thematically analysed to reveal four themes: the design, pedagogy, content and assessment of CEC curricula.

Conclusion Few curricula employ consistent approaches to training. Many programmes fail to provide CEC trainees with sufficient knowledge, skills and experience to meet required competencies. Most programmes do not inculcate prevailing sociocultural, research, clinical and educational considerations into training processes nor provide longitudinal support for CEC trainees. Most CEC training programmes are not supported by host institutions threatening the sustainability of the programme and compromising effective assessment and longitudinal support of CEC trainees. While further reviews are required, this review underlines the need for host organisations to support and oversee a socioculturally appropriate ethically sensitive, clinically relevant longitudinal training, assessment and support process for CEC trainees if CECs are to meet their roles effectively.
