Endoscopic Quality Improvement Program (EQUIP)

Effective colorectal cancer (CRC) screening relies on early identification and removal of both polypoid and non-polypoid lesions with neoplastic potential. The investigators hypothesize that an intensive training program designed to enhance both recognition and classification of lesions with neoplastic potential, will result in an increase in non-polypoid adenoma detection in addition to and independent of an increase in overall adenoma detection rates.

Official Title: The Effect of an Intensive Endoscopic Quality Improvement Program (EQUIP) on Improved Detection and Classification of Non-polypoid (Flat and Depressed) and Polypoid Colorectal Adenomas. ("EQUIP" Study)

Further study details as provided by Mayo Clinic:

Primary Outcome Measures:
  • Measurement of overall adenoma detection rate [ Time Frame: 1 year ]
    Primary outcome measures will include overall and per patient adenoma detection rate for polypoid and non polypoid neoplastic lesions.

Secondary Outcome Measures:
  • Measurement of total polypectomy rate [ Time Frame: 1 Year ]
    Secondary outcomes will include total polypectomy rate (hyperplastic vs. adenoma),

  • Measurement of colonoscopy time [ Time Frame: 1 Year ]
    Total colonoscopy time and endoscopist acceptance. Variables such as patient demographics and prep quality will be adjusted for.

  • Endoscopist Acceptance [ Time Frame: 1 Year ]
    Ensdoscopist acceptance rate will be measured. Variables such as patient demographics and prep quality will be adjusted for.

Experimental: Randomization and Training Arm Other: Training session
Series of two training sessions after the first phase of study followed by monthly feedback.

Detailed Description:
Our Endoscopic Quality Improvement Program (EQUIP) was a prospective educational intervention with our staff endoscopist as our study population. The investigators measured adenoma detection rates for a baseline period then randomly assigned half of the endoscopists to undergo EQUIP training. The investigators then examined baseline and post-training study adenoma detection rates (ADR's) for all endoscopist (trained and un-trained) to evaluate the impact of training.
