On bivariate analysis of sociodemographic factors patients were more likely to receive either curative intent RT or SABR for inoperable NSCLC if the treatment facility was located in a metropolitan compared to a rural location. Treatment facility location was not significant for the remaining QIs. Younger patients were also more likely to receive RT for inoperable stage I to III NSCLC and CRT for both NSCLC and SCLC, but did not influence adjuvant RT, receipt of SABR or timing of RT in SCLC. Country of birth had no effect on receipt of concordant care for all QIs except those born overseas were more likely to receive RT for inoperable NSCLC Stages I to III than Australian born patients (25% vs 20%, p<0.05). There was also a statistically significant trend towards patients of lower socioeconomic status (SES) not receiving CRT for LS-SCLC but not early timing of RT. There was no significant influence of SES on receipt of curative intent RT or CRT for inoperable NSCLC.

Conclusion:

QI measurement related to receipt of radiotherapy for lung cancer was feasible when used in a real world setting with routinely collected linked data. Results were variable across radiotherapy guideline concordance and revealed lower compliance rates for definitive radiotherapy for inoperable Stage I to III NSCLC of 21.9% (n=474) and CRT for LS-SCLC of 30.1% (n=90), which fell below suggested published benchmarks. 2 There was higher compliance for the use of curative intent CRT for NSCLC and low 60-day mortality after treatment. Although, the number of patients with stage III NSCLC and LS-SCLC who received curative intent RT was relatively small, potentially reflecting poor data capture. Better data collection more closely reflecting real-time care received with specified data items for clinically relevant QIs are needed for meaningful measurement of radiotherapy quality in lung cancer. We have also demonstrated the feasibility and potential of using QIs to detect variations in care with sociodemographic factors. Ultimately, the ability to accurately measure care received is the first step to describe and identify gaps. Future work is underway to develop a set of RT specific QIs that are clinically important and feasible, with both the potential to be prospectively collected for benchmarking and to precipitate quality improvement efforts for patients receiving radiotherapy for lung cancer.
