Mean Infrastructure Scores, Percent of “Must Pass” Elements Achieved, and the Proportion of Single-Specialty Group Practices Qualifying for Medical Home Recognition, Stratified by Clinical Specialty

	Estimate (95 Percent Confidence Interval)
Measure of Practices’ Achievement	All Single-Specialty n = 21,016	Primary Care n = 9,014	Medical Specialty n = 7,140	Surgical Specialty n = 4,862	p-Value
Mean infrastructure score*	39.7 (37.0–42.4)	44.3 (39.5–49.2)	34.9 (31.7–38.2)	38.0 (33.5–42.5)	.019
Percent of “must pass” elements achieved	41.4 (38.7–44.0)	45.5 (40.7–50.2)	37.8 (34.0–41.6)	39.0 (34.3–43.6)	.053
Percent of practices with a given level of recognition
Not recognized	34.5 (28.9–40.1)	29.7 (22.1–38.5)	41.0 (31.3–51.5)	33.9 (25.6–43.3)	.238
Level 1	31.7 (26.8–36.6)	29.0 (22.0–37.3)	30.6 (21.5–41.4)	38.3 (30.3–47.0)
Level 2	21.0 (17.1–25.0)	23.6 (17.5–31.1)	19.2 (13.2–27.1)	18.7 (12.7–26.8)
Level 3	12.8 (9.1–16.5)	17.7 (12.3–24.9)	9.2† (4.7–17.2)	9.0 (5.4–14.8)

^*The denominator for a practice's infrastructure score was based on the NAMCS items (that mapped to specific NCQA elements) for which it reported data. The maximum denominator for the score was 59 points; however, the denominator value changed in the setting of missing data.

^†Because it is based on fewer than 30 records or the standard error is more than 30% of the estimate, the National Center for Health Statistics considers this estimate unreliable.
