The Development and Validation of a Quality Assessment and Rating of Technique for Injections of the Spine (AQUARIUS).

Background And Objectives: Systematic reviews evaluate the utility of procedural interventions of the spine, including epidural steroid injections (ESIs). However, existing quality assessment tools either fail to account for proper technical quality and patient selection or are not validated. We developed and validated a simple scale for ESIs to provide a quality assessment and rating of technique for injections of the spine (AQUARIUS).
