Note: CABG = coronary artery bypass graft, CORC = CorHealth Ontario Cardiac Registry, DAD = Discharge Abstract Database, ICU = intensive care unit, IQR = interquartile range, LOS = length of stay, NACRS = National Ambulatory Care Reporting System, OR = operating room, P2–P4 indicates priority level 2 to 4, SETP = Surgical Efficiency Target Program, TOTAL = Trillium Gift of Life Organ and Tissue Allocation System, WTIS = Wait Times Information System.
↵* Regional breakdown can be found in Appendix 1. Percentage of available ORs was modelled as a normal distribution with a mean of 50% and standard deviation of 10%. Turnover time distributions were available from June 2020 from SETP by region. Provincial turnover time across all surgery types was a median of 22 (IQR 12–33) minutes.
↵† Backlog size estimates are reported as the mean (95% prediction interval).
↵‡ OR time, ward LOS and ICU LOS are reported as median (IQR) for 2019 data.
↵§ Provincial historical 2019 attrition rates were available for cancer P2–P3 (0.1%), cancer P4 (0.2%), vascular P2–P4 (0.3%) and transplant (6.1%).
