To evaluate the impact of a clinical quality registry on unwarranted clinical variation, clinical quality indicator attainment, and survival outcomes in lung cancer.
Retrospective observational cohort study evaluating 25 clinical quality indicators in newly diagnosed lung cancer patients (N=12,121).
Conducted using data from the Victorian Lung Cancer Registry in Victoria, Australia, between 2016 and 2021.
Baseline institutional quality indicator attainment varied widely across centers from 2.1% to 90.0%, with longitudinal attainment subsequently increasing in 6 indicators, remaining stable in 17, and decreasing in 2.
Meeting clinical quality indicators was associated with a significant reduction in mortality hazard for 15 indicators (hazard ratio reduced by 10% to 67%) and an increased hazard for 3 indicators (hazard ratio increased by 32% to 48%).
Survival analysis revealed significant improvements in non-small cell lung cancer survival for overall stage I and pre-COVID stages II and IV.
