Cancer surgery cancellation: incidence, outcomes and recovery in a universal health care system.

BACKGROUND: Cancer surgery cancellation can have negative consequences for the patient, the surgeon and the health care system. There is a paucity of literature on cancer surgery cancellation and its association with wait times, perioperative outcomes, survival and costs of care. Therefore, the objective of this study was to determine the incidence of same-day cancer surgery cancellation in a universal health care context and its association with short and long-term outcomes. METHODS: This was a population-based retrospective cancer cohort study in Ontario, Canada (2010-2016). There were 199 599 patients in the control cohort and 3539 patients in the cohort that experienced a cancellation. We assessed the cohorts for differences in survival, perioperative complications and costs of care. RESULTS: The overall cancellation rate was 1.74% and was predicted by cancer type (genitourinary), lower income quintile, and more central region of residence. Wait times in the cancelled cohort were longer than in the control cohort; however, this difference was not associated with worse survival outcomes. Patients in the cancelled cohort had higher complication rates while in hospital (7.3 %) than those in the control cohort (4.9%; p < 0.01). After adjusting for important confounders, the cancelled cohort was more costly ($1100). CONCLUSION: Same-day cancer surgery cancellation rates were low. They were associated with longer wait times, higher complication rates and increased costs of care. Survival was not worse in the cancelled cohort, suggesting that appropriate cancer urgency prioritization occurs. Preventable causes of cancellation should be targeted to improve outcomes in patients with cancer.

How equitable is access to treatment for lung cancer patients? A population-based review of treatment practices in Ontario.

AIM: Guideline concordance is one of the metrics used by the Cancer Quality Council of Ontario and Cancer Care Ontario to assess the quality of cancer care and to drive quality improvement. MATERIALS & METHODS: The rates for lung cancer surgical resection and concordance with the Cancer Care Ontario postoperative adjuvant chemotherapy (AC) guideline were assessed by health region during two time periods (2010-2011 and 2012-2013) according to five equity measures (age, sex, neighborhood income, location of residence and size of immigrant population). RESULTS: Of the patients with stage I/II NSCLC, 52.2% to 63.0% underwent surgical resection in the province of Ontario, Canada; for patients with stage IIIA disease, the rate was 26.4%. The probability of a surgical resection decreased substantially with age; only 26.9% of those with potentially resectable (stage I-IIIA) disease over 80 years underwent surgery. The use of postoperative AC increased modestly over the time of the study but the rate of use varied widely by health region (34.6 to 84.6%). Patients in rural areas were as likely to receive AC as urban dwellers; however, older aged patients (≥65 years) and those from the lowest income neighborhoods were significantly less likely to receive AC. CONCLUSION: Surgical rates and the use of AC vary by health region in Ontario and by age and level of neighborhood income despite universal access in a publicly funded health care system. The reasons for this variance are unclear but warrant further study.Presented in part at the 15th World Conference on Lung Cancer, Sydney, Australia, 27-30 October 2013.
