We write to express our views on the recent study published in your journal, titled “Identifying Predictors for Early Percutaneous Spinal Cord Stimulator Explant at One and Two Years: A Retrospective Database Analysis.”
1Although the study is notable for its large sample size and the valuable insights it provides into the incidence and predictors of spinal cord stimulator (SCS) explant, we believe there are several limitations that should be acknowledged and addressed.

- Identifying Predictors for Early Percutaneous Spinal Cord Stimulator Explant at One and Two Years: A Retrospective Database AnalysisNeuromodulationVol. 26Issue 1
- PreviewPlacement of percutaneous spinal cord stimulator (SCS) implant has become a therapeutic option for various chronic pain conditions; however, early surgical explant still occurs. Unfortunately, evidence regarding the incidence of early surgical explant, and patient-specific factors and comorbidities associated with such, is limited and mixed. The objective of this retrospective analysis was to elucidate the incidence and predictors of percutaneous SCS explant within the first two years of device placement.

- PreviewWe thank Drs. McLean and Schwarz1 for their interest in our work. We agree that claims-based data base research comes with several limitations,2,3 which we address in our manuscript. Notably, there could be error in the reporting of claims, the possibility of coding bias, and inadequate definitions of comorbidities and complications. Furthermore, because of the reliance on diagnosis and procedural codes, granular rationale for clinical decision-making that is not codified (ie, removal of a spinal cord stimulator device due to poor surgical technique) cannot be reliably detected with claims-based data base research.
