ObjectiveA regional anesthesia complication grading system (regional anesthesia outcomes reporting [ROAR]) was developed and applied to 1,213 consecutive patients over a 14-month period. The goal of the project was the creation of a system to standardize complication reporting in the regional anesthesia literature.DesignPatient demographics, status as a war casualty, regional block procedure-specific details, and complication grade were entered into an Internet-based, encrypted Department of Defense database. Regional anesthesia complications were later graded and subcategorized depending on what phase of the block the procedural adverse event took place.ResultsOne thousand ninety-eight (90.5%) patients had neither regional anesthesia associated technical difficulties or more severe complications. Of a total of 147 cases with adverse events among 115 patients (1.3 per patient), the majority (63.3%, 93/147) were low-grade complications resulting in no significant morbidity. The most common complications resulting in patient morbidity were failed block requiring catheter removal and/or supplemental block (35.4%, 17/48). High grade complications represented only 4.1% (6/147) of all peri-procedural morbidity. These complications included pneumothorax requiring tube thoracostomy, transient laryngeal nerve dysfunction, and cancellation of planned operation after peripheral nerve block or catheter placement.ConclusionsThe value of the ROAR system is that it identifies important issues in risk management in regional anesthesia, thereby providing opportunities for further investigation and clinical practice refinement. Furthermore, it provides for a common language when reporting outcomes in the regional anesthesia literature. Use of the ROAR system will provide consistency in outcomes reporting and facilitate comparisons between methods and procedures.
