Modified Cancer Care Ontario quality-of-care indicators for evaluating outcomes in colorectal cancer treatment (17)

IndicatorDefinition
1. Patients diagnosed by screeningProportion of patients diagnosed symptom free by any screening method
2. Adequate colon evaluationProportion of patients with complete colon imaging (colonoscopy or barium enema + sigmoidoscopy) 3 months before surgery of within 6 months after surgery
3. Preoperative liver imaging (CT, MRI, ultrasonography)Proportion of patients with complete preoperative imaging of liver with ultrasonography, CT or MRI
4. Preoperative pelvis imaging in patients with rectal cancer (CT, MRI)Proportion of patients with rectal cancer who had preoperative imaging of the pelvis with CT or MRI
5. Patients with rectal cancer who received NEORTProportion of patients with rectal cancer who saw a medical oncologist preoperatively, or of patients with stage II/III rectal cancer who saw a medical oncologist within 8 weeks of surgery or received preoperative radiotherapy
6. Patients with rectal cancer who received NEOCTProportion of patients with rectal cancer who saw a radiation oncologist preoperatively, or patients with stage II/III rectal cancer who saw a radiation oncologist within 8 weeks of surgery or received preoperative chemotherapy
7. Completeness of the operative reportCompleteness of the surgical report of patients who underwent surgery for rectal cancer; 2 points assigned for each of the following aspects: total mesorectal excision, tumour location, tumour extension, lymphadenectomy, degree of nerve sparing (maximum score possible = 10)
8. Pathology report completeness: lymph nodesProportion of patients whose pathology report indicates the number of lymph nodes examined and the number of positive lymph nodes
9. Pathology report completeness: distal and circumferential marginProportion of patients whose pathology report indicates distal and circumferential margins quantitatively
10. Pathology report completeness: rectal cancer distal margin ≥ 1 cmProportion of patients who underwent surgery for rectal cancer whose distal margin was ≥ 1 cm
11. Anastomotic leakProportion of patients who underwent surgery for rectal cancer who experienced anastomotic leak
12. In-hospital/30-day mortalityDeath in hospital or within 30 days of discharge after colon or rectal cancer surgery
13. Local recurrenceProportion of patients with local recurrence within the pelvis confirmed by histologic examination, diagnostic imaging, colonoscopy and/or biopsy at reoperation
14. Survival rate3- or 5-year overall survival rate
15. Surveillance colonoscopyProportion of patients who underwent surveillance colonoscopy within 1 year after surgery
  • CT = computed tomography; MRI = magnetic resonance imaging; NEOCT = neoadjuvant chemotherapy; NEORT = neoadjuvant radiotherapy.
