This study aims to identify factors associated with longer wait times for colorectal cancer surgery.
Retrospective cross-sectional cohort study of patients undergoing elective colon and rectal cancer resections from November 2023 to November 2025.
Compared baseline characteristics of patients meeting vs. exceeding wait time targets using statistical tests.
Conducted univariate and multivariate logistic regression to identify predictors of surgical delay.
Out of 370 patients, only 135 (36%) met the 21-day wait time target, with a median wait of 27 days.
Central zone surgery and neoadjuvant chemotherapy were associated with increased delays (OR 2.6, p < 0.001 and OR 4.4, p = 0.038 respectively).
Higher ASA score (≥ 3) correlated with lower odds of delay (OR 0.5).

Resumen

Background: Wait times for surgical care for colorectal cancer in Canada are extremely variable, potentially affecting oncologic outcomes.The purpose of this provincial population-level study was to determine patient-, disease-, and system-level factors associated with longer wait times for colorectal cancer surgery.Methods: This was a retrospective cross-sectional cohort study including patients undergoing elective colon and rectal cancer resections between November 2023 and November 2025.Baseline characteristics (clinical and administrative data sets) were compared between patients meeting and exceeding wait time targets (from ready-for-surgery to surgery in 21 days; from pathologic diagnosis to surgery in 42 days) using the Wilcoxon ranksum test for continuous variables and the Pearson χ 2 test for categorical variables.Univariate and multivariate logistic regression was performed to identify factors associated with delay.Results: Of the 370 patients who underwent elective colorectal cancer resections, only 135 (36%) met the 21-day target from ready-for-surgery to surgery, with a median wait time of 27 days.Multivariable regression identified surgery in central zone (tertiary and quaternary care facilities with subspecialty care) and neoadjuvant chemotherapy as factors strongly associated with surgical delay (odds ratio OR 2.6, p < 0.001, and OR 4.4, p = 0.038, respectively).American Society of Anesthesiologists (ASA) score ≥ 3 was associated with lower odds of delay (OR 0.5,
