Benchmarks for the interpretation of esophageal high-resolution manometry

Area of Science:

• Gastroenterology
• Medical Education
• Diagnostic Techniques

Background:

• Accurate interpretation of esophageal high-resolution manometry (HRM) is crucial for quality patient care.
• Currently, no standardized methods exist to assess physician competency in HRM interpretation.
• This study aimed to develop an HRM interpretation exam and establish competence benchmarks.

Purpose of the Study:

• To develop a formal examination for assessing esophageal high-resolution manometry (HRM) interpretation skills.
• To establish minimum competency benchmarks for HRM interpretation at trainee, physician interpreter, and master levels.

Main Methods:

• An HRM interpretation exam was designed based on expert consensus.
• Physicians (n=27) including trainees and experts completed the exam.
• Judges used the modified Angoff method to establish minimum competency cut scores.

Main Results:

• The exam includes 22 HRM cases assessing 8 interpretation skills.
• Minimum cut scores were established for trainee, physician interpreter, and master levels.
• Scores ranged from 65-95% depending on skill and expertise level.

Conclusions:

• Formal standard-setting techniques established minimum cut scores for HRM interpretation skills.
• The developed examination and cut scores can be used to assess clinical competency.
• This tool will enhance the quality of esophageal manometry interpretations.
