  1. SD standard deviation
  2. aStrategic Analytics for Improvement and Learning (SAIL) measure. SAIL is a system for summarizing hospital system performance within VHA
  3. bHospital 5-star rating (1–5) indicates a VA hospital’s quality of care relative to other VA hospitals and is based on data such as death rates, nursing turnover, patient satisfaction, and efficiency [17]
  4. cFacility complexity level classifies VHA facilities at levels 1a, 1b, 1c, 2, or 3 with level 1a being the most complex and level 3 being the least complex. The model is reviewed and updated with current data every 3 years. The peer grouping system is based on seven variables relating to patient population, clinical services complexity, and education and research [18]
