This proposed initiative uses existing methodology to accurately quantify wait times in the thoracic surgical lung cancer pathway for patients treated within the BC Interior. This will allow for the comparison of the fastest and slowest wait times, information that is needed by the Interior Thoracic Group for evaluating thoracic surgical care quality and determining areas of improvement. Currently, the presentation of wait time data is inconsistent between reports and the use of a quantile regression model for measuring these values can be used for quality assurance purposes. This evaluation will also identify and review ways to rectify any points of lag in the lung cancer treatment pathway. Furthermore, this initiative will enable quality assurance monitoring of diagnostic, treatment, and outcomes for surgical lung cancer patients receiving treatment in the BC Interior.
