About this study

Official title: An Integrated Strategy for the Expedited Diagnosis, Referral, Assessment and Treatment of Complex Colorectal Polyps

The purpose of this study is to evaluate the impact of implementing an integrated clinical care pathway for the diagnosis, referral, evaluation and treatment of large complex colorectal polyps on clinical outcomes

Read the detailed description

Our project will create a system that links community hospitals and ambulatory endoscopy centers throughout the province of Ontario, directly to the expert endoscopists at our tertiary referral center, to facilitate the timely assessment of polyps based on an electronic referral containing endoscopic video recordings or high-resolution images rather than a paper report through a centralized referral pathway. This polyp adjudication will happen in a timely fashion without involving in-person patient consultation, and will streamline the management of these patients to either referral for surgery or booking for endoscopic polyp removal by therapeutic colonoscopy at our center. Specific endoscopy time slots will be reserved for these patients to ensure they have efficient access to their treatment. This system represents a new care model for managing patients with concerning pre-cancerous lesions diagnosed in disparate local hospitals through a centralized process of referral, diagnostic evaluation and treatment at an expert tertiary referral centre.

The primary aim of our study will be to track the outcomes of the new standard-of-care clinical pathway. Clinical objectives of the project include a reduction in wait times for expert assessment after diagnosis of a large or otherwise concerning polyp combined with reduced wait times for therapeutic removal of these polyps, minimizing unnecessary surgery for benign lesions, and facilitating early recommendation for surgery in those patients who truly require surgical resection. Additional objectives include the achievement of excellent rates of clinical success, complication rates similar to those reported in the literature, and high levels of satisfaction from referring doctors at participating centers. A final, major goal is to assess whether this pilot program could serve as a model to be expanded to other academic, tertiary referral centers throughout the province of Ontario.

Our primary research question seeks to compare the diagnostic accuracy of expert polyp adjudication between the different modes of referral (video clip, color photograph, faxed images) against the real-time endoscopic diagnosis during therapeutic colonoscopy and the final pathologic result. The secondary research question is to follow the clinical outcomes of all patients who undergo endoscopic mucosal resection (EMR) of a large or complex colorectal polyp to evaluate the efficacy and safety of this procedure at our expert tertiary referral center.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Integrated Large Complex Polyp Referral PathwayOther

    The referring doctor will use a standardized template to send the referral along with its associated video or high-resolution photographs.

    Referrals will be reviewed in a consensus fashion by at least 2 expert physicians at St. Michael's Hospital (SMH) on a bi-weekly basis. Polyps will be scored using a standardized evaluation form that documents relevant polyp features to assist the determination of whether a lesion is amenable to curative endoscopic resection.

    Cases will be triaged as being: (1) a standard polyp suitable for local removal in the community; (2) a complex polyp requiring expert removal at SMH with priority assigned based on the suspected risk of invasive disease; (3) a polyp that is not amenable to endoscopic resection or that is suspicious for cancer will that be recommended for surgical resection.

What is being measured

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

  1. Diagnostic accuracy of remote polyp diagnosis (based on video clips, electronic color photographs or paper-based images) compared to real-time endoscopic diagnosis during therapeutic colonoscopy

    Determination of diagnostic accuracy (reported as sensitivity and specificity) of video-based vs. real-time endoscopic diagnosis of polyps; diagnostic accuracy of electronic color photo-based vs. real-time endoscopic diagnosis of polyps; diagnostic accuracy of paper-based images vs. real-time endoscopic diagnosis of polyps.

    Measured: During Procedure

Secondary outcomes (7)
  1. Patient Wait Times

    Wait times (measured in days) from index colonoscopy to polyp adjudication, and from index colonoscopy to therapeutic polyp removal. Comparison will be made to historical wait times for polyps > 2 cm referred to SMH for polyp removal.

    Measured: During Procedure

  2. Prediction of Polyp Diagnosis

    Polyp diagnosis based on initial colonoscopy performed at the referring centre, video- or photo-based assessment during polyp triage, and real-time evaluation during colonoscopy by expert endoscopist at SMH, assessed against final pathology from resected polyp specimen.

    Measured: Until availability of histology, generally up to 2 weeks post procedure

  3. Need for adjunctive removal

    Rate of complete snare resection of polyps versus need for the use of combined adjunctive techniques (hot/cold avulsion, argon plasma coagulation, etc.) to achieve removal of polyps.

    Measured: During Procedure

  4. Prediction of Successful Endoscopic Treatment

    Accuracy (reported as likelihood ratios) of the correct prediction of successful endoscopic treatment based on initial video-based, electronic colour photo-based, or paper image-based assessment during polyp triage compared to real-time evaluation during colonoscopy (prior to commencing attempt at polyp removal), assessed against final endoscopic outcome.

    Measured: Through study completion, up to 1 year

  5. Procedural complications

    Rate of immediate and delayed complications both intra-procedural and post-procedural up to 4 weeks.

    Measured: Up to 4 weeks

  6. Residual/Recurrent Polyp

    Rate and predictors of residual or recurrent polyp at follow-up surveillance colonoscopy.

    Measured: 6 months

  7. Referring Physician Satisfaction

    Study specific survey consisting of a 5 point likert scale ranging from 1 ("extremely dissatisfied") to 5 ("extremely satisfied"). Assessed at 1 year from initial referral.

    Measured: 1 year

Questions about this trial

What is this clinical trial studying?

An observational study of Polyp Colorectal, run by Unity Health Toronto.

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 2 inclusion and 2 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: status not confirmed, as of the sponsor's last update on 17 Nov 2020. Status can change between updates, so confirm with the study contact before making plans.

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?

Results are not available in the source record.

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

Contact Christopher Teshima, MD ((416) 864-5646, Christopher.Teshima@unityhealth.to), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Diagnostic accuracy of remote polyp diagnosis (based on video clips, electronic color photographs or paper-based images) compared to real-time endoscopic diagnosis during therapeutic colonoscopy (time frame: During Procedure). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 17 Nov 2020.
