Patient Satisfaction With Spinal Cord Stimulation and Dorsal Root Ganglion Stimulation for Chronic Intractable Pain: A Systematic Review and Meta-Analysis

Synopsis

This systematic review and meta-analysis aims to determine the rate of patient satisfaction with the use of SCS and DRG-S in the treatment of chronic intractable pain. We queried articles from multiple electronic data bases, including MEDLINE, EMBASE, and Cochrane Central Register of Controlled Trials data bases, and hand-searched reference lists of identified publications. Our search strategy identified 242 unique citations, of which nine RCTs and 23 observational studies were included for analysis. Overall, 25 studies comprising 1355 participants were pooled in our quantitative analysis. The pooled proportion of patients who self-reported satisfaction from all studies was 82.2% (95% CI, 77.8%-86.2%). Our results show high levels of patient satisfaction across the SCS and DRG-S literature when these treatment modalities are used for chronic intractable pain. However, there is a scarcity of unbiased and/or non-industry-funded prospective studies in the neuromodulation field, and future efforts to expand this area of the SCS and DRG-S literature are greatly needed.
