Expert consensus on serratus anterior plane block education and credentialing: A modified-Delphi study.

OBJECTIVE

The serratus anterior plane block (SAPB) is a regional anaesthesia technique with increasing use as an analgesic adjunct in patients with rib fractures. The present study aimed to generate consensus of the requirements of education, training and credentialing for the use of a 'single shot' SAPB in the management of rib fractures.

METHODS

A modified Delphi process was designed using online questionnaires. Expert panellists from Australian and Aotearoa New Zealand were invited from the fields of Emergency Medicine and Anaesthesia and were asked to rate the importance of different components of SAPB education, training and credentialling on a 9-point Likert scale. Consensus was achieved if ≥70% of experts provided a score of seven or greater on this scale for any given statement.

RESULTS

Thirty specialists (60% FACEM, 40% FANZCA) representing New Zealand plus all states and territories of Australia formed the expert panel. Participant response rates were 100% (first round), 83% (second round) and 63% (final round). At the end of three survey rounds, 59 consensus statements were formed (27 for education, 5 for training and 17 for credentialing).

CONCLUSIONS

This series of expert statements provides consensus on the education, training and credentialling of the SAPB for the management of rib fractures. These serve as the minimum standard by which this procedure should be taught while providing clinicians with a syllabus for the development of training programmes.
