PG - e157-e164 LID - S1878-8750(18)30038-X [pii] LID - 10.1016/j.wneu.2017.12.183 [doi] AB - OBJECTIVES: In the study, we discuss the predictive value and cost-effectiveness of dorsal root ganglion (DRG) blocks before using dorsal root ganglion pulsed radiofrequency (DRG-PRF) in the treatment of low back pain. METHODS: The study comprised 60 patients with low back pain who were randomly assigned into 2 groups. Patients in group 1 were screened using DRG block before DRG-PRF treatment for responders. Patients in group 2 underwent DRG-PRF treatment without DRG block. Successful outcome was defined as patient satisfaction, improvement in numerical rating scale, and medication use reduction. RESULTS: In group 1 (n = 30), 24 patients demonstrated good response to DRG block, and 20 patients had successful outcome at 6 months after DRG-PRF therapy. In group 2 (n = 30), 25 of the patients had successful outcome at 6 months after DRG-PRF therapy. The mean medical costs were NT$ 19,245 and NT$ 16,375 for each successful case in groups 1 and 2, respectively. CONCLUSIONS: In this comparative cost-effectiveness study, the application of diagnostic DRG blocks before DRG-PRF did not have a significant impact on patient satisfaction, pain index score, or pain medication reduction. Furthermore, the application of diagnostic DRG blocks resulted in overall greater medical costs. These findings suggest that DRG-PRF without screening by DRG block is more cost-effective and less invasive. CI - Copyright (c) 2018 Elsevier Inc. All rights reserved.
