Authors' conclusion

Despite time investments, DIBH is cost-effective in the Belgian population.

Study context

Population
Patients with left-sided breast cancer receiving radiotherapy (Belgian population)plans with both techniques
Participants
100 patients
Comparison
Deep inspiration breath hold (DIBH) vs free breathing (FB)
Outcome
Cost-effectiveness of DIBH vs FB (incremental cost-effectiveness ratio per QALY)
Follow-up
20 years

Main finding

As reported in the abstract

Cost-effectiveness (ICER)
DIBH
incremental cost 617 € per left-sided breast cancer patient (95% CI €615-€619)
DIBH
incremental quality-adjusted life-years (QALYs) 0.04 QALYs per patient (95% CI 0.05–0.05)
ICER (willingness-to-pay threshold €40,000)
€14,023 per QALY
