Study summary

The goals of this project are to learn whether a quality improvement report card assessing technical skills from AI-augmented expert review of video recordings improves doctors' colonoscopy performance. Colonoscopy performance is important because colonoscopies are how doctors detect and remove pre-cancerous polyps. The participants in this study are doctors, usually surgeons, who perform some colonoscopies as part of their practice. These doctors usually do not receive feedback on their performance, and therefore lack information on how to potentially improve their ability to detect and remove pre-cancerous polyps.

The main questions it aims to answer are:

  1. Are there ways we should customize the colonoscopy quality improvement report card to the participating doctors?
  2. Does customizing the report card lead to better acceptance of the information shared?

(2) Does the colonoscopy quality improvement report card improve doctors' colonoscopy performance?

Read the detailed description

Colonoscopy reduces the risk of colorectal cancer (CRC) mortality through the detection and removal of pre-cancerous polyps (adenomas), but the magnitude of risk reduction depends upon the quality of the colonoscopy. Most colonoscopy quality improvement (QI) initiatives have focused on higher-volume gastroenterologists. In rural and peri-urban communities in the United States, most colonoscopies are performed by lower-volume colonoscopists, who are mostly surgeons, and CRC outcomes are worse compared to urban areas. These lower-volume colonoscopists have marked variability in quality and many fail to adhere to best practices or meet national benchmarks. Higher adenoma detection rate (ADR) is the quality metric most associated with reduced CRC mortality. However, ADR is less accurate at lower colonoscopy volumes, suggesting that ADR alone cannot reliably differentiate quality or provide meaningful information to improve quality in lower-volume colonoscopists. Thus, alternative methods to measure and improve quality in lower-volume colonoscopists are needed. Video evaluation of procedures such as colonoscopy is a valuable tool for assessing and improving technical skills in multiple specialties. In prior work, we found that higher-volume gastroenterologists' colonoscopy skill, assessed by expert evaluation of video-recorded colonoscopies using a validated technical skill scoring rubric, is highly correlated with quality metrics requires fewer colonoscopies for accurate assessment, and correlates with ADR. Further, we showed that delivery of focused feedback based on technical skill scores improves colonoscopy quality. While expert video evaluation of colonoscopies is an effective tool to measure and improve quality in lower-volume colonoscopists, it is not feasible on a larger scale given the time and cost of manual video review. We therefore developed and validated an AI-based tool that identifies key steps in colonoscopy videos, for rapid expert review and scoring. This study focuses on the implementation and evaluation of an AI-augmented intervention to improve colonoscopy quality of lower-volume colonoscopists in rural and peri-urban areas to ultimately reduce CRC mortality. The intervention, the "Colonoscopy Quality Improvement Bundle" (ColonQI Bundle), combines (1) AI-augmented expert assessment and scoring of technical skills; (2) AI-augmented automated calculation of quality metrics (e.g., ADR, withdrawal time), and (3) Targeted feedback of specific technical skill deficits based on the scores (audit-feedback, structured video-based didactics, coaching, mentoring). Lower-volume colonoscopists, with a focus on surgeons will be recruited to: (1) Assess the needs and preferences of, and select strategies for implementation of the ColonQI Bundle using an implementation science framework; (2) Implement the ColonQI Bundle, using tailored implementation strategies tailored to the needs and preferences of lower-volume colonoscopists; and (3) Assess the effectiveness of the ColonQI Bundle to improve colonoscopy quality and technical skills among lower-volume colonoscopists.

What researchers measure

Primary outcomes

  1. Pre-post Change in Adenoma Detection Rate (ADR) at the individual and cohort levels

    The rate at which a colonoscopist detects adenomas (pre-cancerous polyps) during a colonoscopy in an average-risk population.

    Time frame: From baseline (the end of the pre-ColonQI Bundle period, prior to the delivery of the ColonQI Bundle) through study completion, an average of 1.5 years.

Secondary outcomes

  1. Colonoscopist technical skill scores (E-CTSS) assessed by expert review of video-recorded colonoscopies at the individual and cohort levels

    Total E-CTSS score; composite of 3 individually scored skills (cleaning, distention, and examination behind colon folds)

    Time frame: From baseline (the end of the pre-ColonQI Bundle period, prior to the delivery of the ColonQI Bundle) through study completion, an average of 1.5 years.

  2. Pre-post Change in Withdrawal time (WT) at the individual and cohort levels

    Time spent inspecting the colon for polyps in screening and surveillance colonoscopies (not including time spent on polyp removal or biopsies)

    Time frame: From baseline (the end of the pre-ColonQI Bundle period, prior to the delivery of the ColonQI Bundle) through study completion, an average of 1.5 years.

  3. Pre-post change in Sessile serrated polyp detection rate (SDR) at the individual and cohort levels

    Proportion of colonoscopies in which a serrated polyp is removed

    Time frame: From baseline (the end of the pre-ColonQI Bundle period, prior to the delivery of the ColonQI Bundle) through study completion, an average of 1.5 years.

Timeline

1 registry update since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Start is estimated for Nov 2026; primary completion for Oct 2028, 23 months later.

Of 899 non-industry interventional studies with no phase under Colorectal Neoplasms, half reached primary completion within 32 months of starting (the median), counting those still running; a quarter within 15 and three quarters within 62. This study's planned 23 months is below that.

Counting every sponsor, half of 956 studies reached it within 32 months; a quarter within 14 and three quarters within 60.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
