Evidence-based estimation and radiotherapy utilisation rate in Andalusia

Area of Science:

• Oncology
• Radiotherapy Research
• Healthcare Management

Background:

• Estimating evidence-based radiotherapy needs is crucial for optimal cancer care.
• Understanding the gap between theoretical needs and actual radiotherapy treatment (RDT) delivery is essential for resource allocation.
• Analyzing trends in RDT utilization provides insights into healthcare system performance.

Purpose of the Study:

• To estimate the evidence-based radiotherapy needs in Andalusia.
• To compare these needs with the actual utilization of RDT in 2006.
• To analyze the evolution of RDT use from 2003 to 2006.

Main Methods:

• Quantitative variables were analyzed using Pearson's correlation coefficient.
• Differences between administered/estimated and actual treatments were assessed using the Student's t-distribution.
• Qualitative variables were analyzed using the Chi-squared test (Xi2).

Main Results:

• The evidence-based radiotherapy rate in Andalusia was 55%, with 85% of theoretical treatments administered in 2006.
• Treatment administration varied by cancer type: 107% for gynecological, 100% for breast, 71% for head and neck, and 48% for lung cancer.
• Significant regional differences in irradiation rates (p<0.0002) and resource distribution were observed. Public hospital treatments increased by 17% over three years.

Conclusions:

• Despite increased RDT utilization, significant underuse occurs for lung and head and neck cancers.
• Substantial variability in RDT use exists across different hospitals in Andalusia.
• Further optimization of radiotherapy services is needed to address disparities and ensure equitable access to care.
