Does Quality of Care Matter? A Study of Adherence to National Comprehensive Cancer Network Guidelines for Patients with Locally Advanced Esophageal Cancer.

INTRODUCTION: The aim of this study was to assess whether adherence to National Comprehensive Cancer Network (NCCN) guidelines leads to differences in survival in patients diagnosed with locally advanced esophageal cancer. METHODS: This is a retrospective cohort study of patients with stage II and III esophageal cancer included in the Cancer Registry at the Sidney Kimmel Comprehensive Cancer Center at the Johns Hopkins Hospital from 2008 to 2013. Seven quality indicators were identified using the 2014 NCCN guidelines, and individual and overall quality measure scores were calculated and used to define low and high quality of care groups. RESULTS: One hundred forty-one patients met inclusion criteria, and 88 patients (62.4 %) were identified as receiving high-quality care. Adherence to guidelines ranged from 63.1 to 100.0 %, with an overall compliance of 81.3 %. Risk factors for receiving low quality of care included advanced age, non-white race, lower education level, and unspecified primary site of tumor. A significantly better overall survival was observed in patients who received high-quality care (HR, 0.58; 95 %, 0.37-0.90, p = 0.015). CONCLUSIONS: Delivery of high-quality care is associated with improved survival in these patients. Efforts should be directed at minimizing disparities in treatment in regards to race and educational levels.
