Abstract: Introduction: This study describes the patterns of use and processes of care following colonic stent insertion for patients with colorectal cancer (CRC) in clinical practice. Methods: Ontario residents who had a colonic stent placed for CRC between 2000–2009 were identified using linked administrative databases. Baseline patient, physician, and institutional characteristics were extracted. The cohort was followed for death and health services utilization post-stent. Results: Two hundred twenty-five patients were identified. Median overall survival post-stent insertion was 199 days (interquartile range [IQR] 153-282). Eighty-five (38%) patients required a subsequent intervention (abdominal surgery, restenting, and/or dilatation). Median intervention-free survival was 75 days (IQR 59-91). Following stent insertion, the average rate of ER visits was 2.4 visits per person-year of follow up (95% CI, 2.2-2.7) and the overall average days spent in hospital was 19 inpatient days per person-year (95% CI, 18-19). Conclusions: In clinical practice, many patients required another intervention shortly after stent insertion; however, the rate of post-stent ER visits and inpatient hospital days was low.
