Results: The mean QALY difference (SWL vs. URS) was –0.021 (950.033 to –0.010) and the mean cost difference was –£809 (95£1061 to –£551). The QALY difference translated into approximately 10 more healthy days over the six-month period for the patients in the URS care pathway. The probability that shockwave lithotripsy is cost-effective is 79s willingness to pay for a quality-adjusted life-year of £30,000 and 9820,000 society's willingness to pay for a QALY threshold.
Conclusion: The SWL pathway results in lower QALYs than URS but costs less. The incremental cost per QALY is £39,118 cost saving per QALY loss with a 79effective at £30,000 society’s willingness to pay for a QALY threshold and 9820,000 society’s willingness to pay for a QALY threshold. Decision-makers need to determine if costs saved justify the loss in QALYs.
