OBJECTIVES: Within the research, we focus on the predictive worth and cost-effectiveness of dorsal root ganglion (DRG) blocks earlier than utilizing dorsal root ganglion pulsed radiofrequency (DRG-PRF) within the remedy of low again ache.
METHODS: The research comprised 60 sufferers with low again ache who have been randomly assigned into 2 teams. Sufferers in group 1 have been screened utilizing DRG block earlier than DRG-PRF remedy for responders. Sufferers in group 2 underwent DRG-PRF remedy with out DRG block. Profitable consequence was outlined as affected person satisfaction, enchancment in numerical ranking scale, and medicine use discount.
RESULTS: In group 1 (n = 30), 24 sufferers demonstrated good response to DRG block, and 20 sufferers had profitable consequence at 6 months after DRG-PRF remedy. In group 2 (n = 30), 25 of the sufferers had profitable consequence at 6 months after DRG-PRF remedy. The imply medical prices have been NT$ 19,245 and NT$ 16,375 for every profitable case in teams 1 and a couple of, respectively.
CONCLUSIONS: On this comparative cost-effectiveness research, the applying of diagnostic DRG blocks earlier than DRG-PRF didn’t have a big impression on affected person satisfaction, ache index rating, or ache remedy discount. Moreover, the applying of diagnostic DRG blocks resulted in total higher medical prices. These findings counsel that DRG-PRF with out screening by DRG block is more cost effective and fewer invasive.
