A Competency-Based Evaluation Checklist for the Pericapsular Nerve Group (PENG) Block: A Delphi Study

Area of Science:

• Regional Anesthesia
• Ultrasound-Guided Procedures
• Pain Management

Background:

• The Pericapsular Nerve Group (PENG) block is an innovative ultrasound-guided regional anesthesia technique for hip surgeries.
• It targets articular nerves, preserving motor function and facilitating early ambulation while reducing opioid consumption.
• Current inconsistencies in PENG block techniques hinder optimal and reproducible results.

Purpose of the Study:

• To develop and validate a competency-based checklist for performing the PENG block.
• The checklist aims to standardize the technique and improve provider competency.

Main Methods:

• The Modified Delphi Method was employed, involving 25 regional anesthesia experts.
• Surveys were distributed, with 16 experts participating in the first round.
• Consensus was reached on checklist items, focusing on anatomical landmarks and post-block procedures.

Main Results:

• A consensus of over 75% was achieved on all checklist items.
• Specific agreement was noted for anatomical landmarks and post-block procedures.
• Feedback highlighted the need for flexibility in ultrasound image acquisition within a standardized framework.

Conclusions:

• A validated, competency-based checklist for the PENG block was developed.
• Standardization through this checklist is expected to enhance provider competence.
• This will likely lead to improved patient outcomes and fewer complications in hip surgeries requiring PENG block.
