Testing criterion-based benchmarking for the appropriate use of radiotherapy

Area of Science:

• Health Services Research
• Radiation Oncology
• Cancer Care Planning

Background:

• Effective planning for radiotherapy (RT) services necessitates accurate data on patient proportions requiring treatment.
• Criterion-Based Benchmark (CBB) is a Canadian model for estimating optimal radiotherapy utilization.
• This study evaluates the applicability of CBB in an Australian healthcare context.

Purpose of the Study:

• To assess the Criterion-Based Benchmark (CBB) model's effectiveness in estimating radiotherapy utilization outside of Canada.
• To compare radiotherapy utilization rates in Australian health system areas meeting CBB criteria versus the general population.

Main Methods:

• Radiotherapy data from New South Wales (NSW) and Australian Capital Territory (ACT) for 2004-06 were analyzed.
• Criterion-Based Benchmark (CBB) Local Government Areas (LGAs) were defined by specific service delivery criteria (no patient payment, specialized oncologists, salary-based, proximity, and waiting times).
• Radiotherapy utilization was compared between CBB LGAs and all LGAs.

Main Results:

• 26% of 98,000 eligible cancer patients received radiotherapy in NSW and ACT.
• Radiotherapy utilization was 31% in CBB LGAs compared to 26% in all LGAs.
• Utilization in CBB LGAs was 7-16% higher but 30-65% below estimated optimal rates.

Conclusions:

• While CBB areas showed higher radiotherapy utilization, rates remained suboptimal and significantly lower than Canadian benchmarks.
• The assumption of perfect service delivery within CBB areas may not hold true universally.
• The CBB approach's reproducibility in diverse healthcare systems outside Canada is questionable.
