The HARM score for gastrointestinal surgery: Application and validation of a novel, reliable and simple tool to measure surgical quality and outcomes

Background: The HospitAl length of stay, Readmissions and Mortality (HARM) score is a simple, inexpensive quality tool, linked directly to patient outcomes. We assess the HARM score for measuring surgical quality across multiple surgical populations. Methods: Upper gastrointestinal, hepatobiliary, and colorectal surgery cases between 2005 and 2009 were identified from the Healthcare Cost and Utilization Project California State Inpatient Database. Composite and individual HARM scores were calculated from length of stay, 30-day readmission and mortality, correlated to complication rates for each hospital and stratified by operative type. Results: 71,419 admissions were analyzed. Higher HARM scores correlated with higher complication rates for all cases after risk adjustment and stratification by operation type, elective or emergent status. Conclusions: The HARM score is a simple and valid quality measurement for upper gastrointestinal, hepatobiliary and colorectal surgery. The HARM score could facilitate benchmarking to improve patient outcomes and resource utilization, and may facilitate outcome improvement. (C) 2016 Elsevier Inc. All rights reserved.
