Cooled radiofrequency ablation of the genicular nerves for chronic pain due to osteoarthritis of the knee: a cost-effectiveness analysis based on trial data

Table 5 Secondary analyses: deterministic mean differences between CRFA versus IAS

Analysis	Incremental QALY gain	Incremental cost (US$)	Cost per QALY gained (US$)
Real world cost scenario 1: IAS in-office, CRFA outpatient, nerve block only applied to CRFA group and still performed in outpatient setting
6-month time horizon	0.091	1929.97	21,166
12-month time horizon	0.229	1929.97	8296
Real world cost scenario 2: IAS in-office, CRFA outpatient, nerve block only applied to CRFA patients but performed in-office
6-month time horizon	0.091	1550.98	17,564
12-month time horizon	0.229	1550.98	6768

Abbreviations: CRFA cooled radiofrequency ablation, IAS intra-articular steroid, QALY quality-adjusted life-years
