Capturing adverse events in elective orthopedic surgery: comparison of administrative, surgeon and reviewer reporting E nsuring adverse event (AE) recording is standardized and accurate can bring about improvements in patient care, and may help hospitals track quality-improvement indexes, leading to improved postoperative outcomes and reduced expenditures. However, there is still no one method, tool or protocol that is effective at capturing all AEs. The Spine Adverse Events Severity System (SAVES) has been successfully implemented to record AEs in spine surgery. 1 The Orthopedic Surgical Adverse Events Severity System (OrthoSAVES) is a modification of SAVES that has been used to record AEs in general orthopedic surgery procedures. 2 By using SAVES and OrthoSAVES, we previously showed that independent clinical reviewers reported more AEs than orthopedic surgeons in elective orthopedic surgical patients. 3 Currently, AEs are often captured by hospital administrative discharge abstract coders via a retrospective review of physician directives in medical charts after discharge. This can be inefficient and incomplete owing to the nature of the coding, and can often not be linked back directly to the chart itself. 4 In this discussion we outline our comparison of AE data recorded by orthopedic surgeons and independent clinical reviewers using SAVES and OrthoSAVES against AE data recorded by hospital administrative discharge abstract coders as well as our assessment of the appropriateness of using OrthoSAVES across the general orthopedic surgery population, including spine patients. What We did All elective orthopedic surgical patients operated on by 1 of 6 surgeons (3 spine, 1 hip, 1 knee, and 1 shoulder) over a 10-week period at a tertiary-care teaching hospital were included.
