About this study

The investigators conducted a study "Resect and Discard Diminutive Polyps: a new paradigm" (IRB ID # 201105473) from September, 2011 to July, 2013. This study examined whether doctors performing colonoscopy are accurate enough at predicting histology of small colorectal polyps, such that these small polyps could be resected and discarded (instead of being sent to pathology). One of the main advantages of this approach is significant cost savings by reducing pathology costs associated with screening and surveillance colonoscopy. A disadvantage is that there is a 0.03% chance that small polyps contain cancer. There is no data regarding patient preferences toward this approach. The investigators therefore designed a patient survey to determine the patient's view toward this approach.

Read the detailed description

The American Society of Gastrointestinal Endoscopy (ASGE) published a review article on a new paradigm in colorectal cancer screening termed "resect and discard". This new paradigm challenges the current practice of sending all colorectal polyps, regardless of appearance or size, to pathology for analysis. "Resect and Discard" describes a new approach in which small polyps could be removed, but be discarded instead of sent for pathology analysis. This is based on data showing that gastroenterologists can predict the pathology of small colorectal polyps with 80-90% accuracy, and that discarding small polyps would not alter surveillance recommendations.

Neither the ASGE document nor published research, however, assessed patient attitudes toward this approach. This study surveyed patients prior to first time screening colonoscopy, in order to determine their preferences about the resect and discard approach; specifically would patients be willing to pay for pathology analysis of small colorectal polyps with their own money, and what factors influence their decision. We also inquired about factors that would influence their decision to pay/not pay pathology costs themselves.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Number of participants willing to pay out of pocket for pathology costs when a diminutive polyp is found.

    This outcome is measured in percentage.

    Measured: June, 2012 to March, 2014: up to 2 years

Secondary outcomes (1)
  1. The factors that influence patients' decisions to pay or not pay for pathology costs with their own money.

    These factors were measured using univariate analysis with generation of odds ratios and 95% confidence intervals.

    Measured: June, 2012 to March, 2014: up to 2 years

Questions about this trial

What is this clinical trial studying?

An observational study of Colonic Polyps, run by Washington University School of Medicine at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 1 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 11 May 2017. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Number of participants willing to pay out of pocket for pathology costs when a diminutive polyp is found. (time frame: June, 2012 to March, 2014: up to 2 years). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT02305251, which also lists 3 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 11 May 2017.
