Background and Aims. A colonoscopy triage sheet (CTS) integrating 6 hierarchical scheduling priorities based on indications
for screening, surveillance, or symptoms was designed for colonoscopy referral. We compared CTS priority ratings by referring
physicians and endoscopists, assessing yields. Methods. Retrospective study of consecutive patients. Data were collected on
demographics, CTS and endoscopist priority ratings, and endoscopic fndings. Weighted kappa values measured interrater
agreement on priority assignment. Predictors of agreement and lesions were identifed using multivariable analysis. Results. Among
1230 patients (60.3 years, 52.5% female), clinically signifcant lesions included tumors (1.1%), polyps per patient ≥ 10mm (7.6%),
and ileocolitis (4.6%). Moderate agreement was found between referring physician and endoscopist on all 6 priorities (weighted
kappa 0.55 (0.51; 0.59)). P4 and P5 ratings predicted increased agreement (range of OR for P4: 2.47–4.57; P5: 1.58–2.93). Predictors
of clinically signifcant fndings were male gender (OR 1.44, 1.03–2.03) and P1/P2 priorities that were signifcantly superior to P3
(OR = 2.14; 1.04–4.43), P4 (OR = 2.90; 1.35–6.23), and P5 (OR = 4.30; 2.08–8.88). Conclusion. Priority-assignment agreement is
moderate and highest for less urgent ratings. Predictors of clinically signifcant fndings validate the hierarchal priority scheme.
Broader validation and physician education are needed.
1. Introduction
Colorectal cancer (CRC) is a major cause of death worldwide.
Colorectal cancer is the third most commonly diagnosed
cancer in Canada (excluding nonmelanoma skin cancers) and
it is the second leading cause of death from cancer in men
and the third leading cause of death from cancer in women
in Canada [1]. Endoscopic resources are, however, in most
regions of Canada limited with both selected screening (pos-
itive FOBT or imaging) and symptomatic patients requiring
a timely colonoscopy.
Amidst long delays in access to health care services
in Canada, the Canadian Association of Gastroenterol-
ogy (CAG) developed evidence-based recommendations for
appropriate maximal wait times for colonoscopies in order
to promote the efcient and equitable use of endoscopic
resources [2].
Based on the CAG guidelines and in the context of
an Open-Access Endoscopy system (without a prior clinic
consultation with the endoscopist), a 1-page colonoscopy
triage sheet (CTS) was developed for the entire province
to improve the quality, efciency, and equitable delivery of
