Although weak associations with outcome were noted for several clinical variables, none was strongly associated with trial and permanent implantation results. The strongest predictor of a negative SCS outcome was obtaining <50% pain relief during the trial period.

Our prospective observational study suggests that anesthesiology-related reasons may be an important factor for not undertaking these techniques. Although we did not specifically examine the effect on resident education, our study does provide some evidence to support program directors and department chiefs to set up their regional rotations with faculty most likely to perform RA.
