FQHC = federally qualified health center; FTE = full-time equivalent; NCQA = National Committee for Quality Assurance.
Note: Includes the 20 practices used in this study. Five other practices were excluded because they had no data for this study.
↵a Practice size based on the number of FTE clinicians in each practice, as follows: solo/partner = 1–2 FTE clinicians; small = 3–4 FTE clinicians; medium = 5–9 FTE clinicians; large = ≥10 FTE clinicians.
↵b To achieve NCQA level 1 recognition, practices must comply with at least 5 of 10 must-pass elements in practice standards; achieving level 2 or 3 depends on overall scoring and compliance with all 10 elements (http://www.ncqa.org/portals/0/PCMH%20brochure-web.pdf).
↵c Community-based practice owned by a system.
