Closed malpractice claims can provide insight into low-frequency adverse events in many areas of perioperative and chronic pain care. Over the last decade, there have been changes in surgical and regional anesthetic practice, likely impacting adverse event patterns. Given the wide variability and low frequency of complications associated with peripheral nerve blocks, the study of closed malpractice claims offers an opportunity to examine adverse events, and the patient, technical, and provider factors that led to the claim. Knowledge gained from examination of closed claims has already resulted in multiple improvements in processes of care and patient safety. ⋯ Regional, pain, anesthesia, complications, closed claims, liability, nerve, block, injury.
