Comparing Microvascular Outcomes at a Large Integrated Health Maintenance Organization With Flagship Centers in the United States

Abstract

OBJECTIVE: To determine if patients undergoing microvascular reconstructive head and neck surgery (MRHNS) at a large integrated health maintenance organization can expect outcomes similar to some of the best or flagship centers in the United States. DESIGN: Outcomes (flap loss, mortality, length of stay), eligibility (recent consecutive US center experience), high-experience (100 cases), high-volume (26 cases per year), and flagship criteria were prospectively defined. A systematic MEDLINE search identified 17 eligible reports. Independent, blinded medical reviewers identified 5 centers (29%) as flagship centers. PATIENTS: The first 116 consecutive patients (average, 39 cases per year) who underwent MRHNS on this service. RESULTS: All 5 flagship centers are major academic health centers ranked in the top 18 "best head and neck hospitals" in the United States. Flap loss (1.7% vs 4.4% for flagship centers; range, 0.9%-8.8%) and mortality (2.6% vs 2.8% for flagship centers; range, 0.5%-6.3%) rates were not significantly different. Although lengths of stay in flagship centers were similar to each other and the literature (mean, 21.4 days; range, 20.1-22.5 days), our length of stay was significantly shorter (8.8 days, P<.001). CONCLUSION: For high-experience and high-volume centers, patients undergoing MRHNS at a large integrated health maintenance organization can expect morbidity and mortality outcomes similar to flagship centers in the United States, with shorter hospitalizations.
