All standard HN patients from January 2015- September 2025 (excluding deceased patients) were included in this retrospective analysis. Data extracted from MOSAIQ included approved timestamps, case complexity (2721 photon and 236 proton patients) and different imaging methods (2D, 3D-CBCT and proton 3D-CBCT). Multiple linear regression analysis (p<0.05) was conducted to assess the trend in the number of images reviewed by APRT and radiation oncologists (ROs) over time. Total time savings were quantified by comparing review durations between ROs and APRT, adjusted for imaging complexity. Economic impact was estimated by applying hourly salary differentials to total time saved. Incremental cost-effectiveness ratio (ICER) was computed as cost difference per hour between APRT and RO-led workflows divided by accuracy difference, incorporating salary-based valuation of time savings. Results: Analysis revealed a significant shift in image review responsibilities over the study period. The images reviewed by APRT demonstrated a marked upward trend while ROs declined correspondingly (Figure 1). This pattern was supported by a significant time– profession interaction (B= –0.271, p<0.001), indicating that as APRT increasingly assumed image review duties, ROs’ involvement progressively diminished. ICER analysis showed SGD$15,105 per 100% accuracy gained, or SGD$151 per 1% difference, indicating APRT-led image review is highly cost-saving with negligible quality compromise (99% vs 100%)3. Image review accuracy was comparable between APRT and ROs, supporting APRT-led review as a practical, value- driven model. Estimated savings were SGD$151/review hour. Over 10 years, APRT completed 404 hours of image review (Table 1), yielding approximately SGD$61,000 in savings. These findings highlighted significant economic benefits without impacting clinical quality.
Conclusion: Collaboration with ROs in HN image review represents a viable, value-based innovation. Evidence strongly demonstrates APRT’s positive impact on unprecedented clinical and service outcomes while enabling ROs to focus on research, complex cases and seeing more patients. This approach improves departmental efficiency and exemplifies a modern, team-based model aligned with healthcare priorities of cost-effectiveness, safety, efficiency and sustainability.
