Cost effectiveness of intermediate-risk squamous cell carcinoma treated with Mohs micrographic surgery compared with wide local excision - 27/01/22
Abstract |
Background |
The efficacy of Mohs micrographic surgery (MMS) in treating cutaneous squamous cell carcinoma has been demonstrated. The cost effectiveness of MMS has rarely been studied to support the perceived higher cost.
Objective |
Perform a cost-effectiveness analysis to determine whether MMS is cost effective over wide local excision (WLE) for Brigham and Women's Hospital tumor stage T2a cutaneous squamous cell carcinoma over a 5-year period.
Methods |
A Markov model with a 5-year time horizon was created using variables from published data. Costs in United States dollars and quality-adjusted life-years (QALY) were calculated.
Results |
MMS was $333.83 less expensive ($4365.57 [95% CI, $3664.68-$6901.66] vs $4699.41 [95% CI, $3782.94-$10,019.31]) than WLE. MMS gained 2.22 weeks of perfect health (3.776 QALY [95% CI, 3.774-3.777] for MMS and 3.733 QALY [95% CI, 3.728-3.777]) over 5 years. The incremental cost-effectiveness ratio was -$7,822.19. MMS had a 99.9% probability of being more cost effective than WLE. Annualized savings of choosing MMS over WLE would be $200 million and over 25,000 QALY. MMS could cost 3.1 times its current rate and remain cost effective.
Limitations |
Relied on data from external retrospective sources.
Conclusion |
MMS is less costly and more effective than WLE and should be strongly considered for stage T2a cSCC, given improvements in costs and QALY.
