TABLE 4. Multivariate Generalized Estimating Equations Model Analysis of Hospital Characteristics Associated with Community-Associated MRSA Isolation (spa type t008).

	All isolates		Hospital-onset infection isolates		Community-onset infection isolates
Hospital characteristic	OR (95% CI)	P	OR (95% CI)	P	OR (95% CI)	P
Annual admissions (per 1,000 patients)	0.97 (0.96–0.98)	<001	0.98 (0.96–1.0)	.045	0.97 (0.95–0.98)	<001
Percentage Medicaid insured patients	1.2 (1.1–1.3)	.002	1.2 (1.1–1.4)	.002	1.2 (1.1–1.3)	.001
Percentage patients with low Romano score^a	1.3 (1.1–1.5)	<001	1.3 (1.1–1.6)	.004	1.1 (0.9–1.4)	.5

NOTE. CI, confidence interval; OR, odds ratio.

Romano score ranges from 0 to 6; a score less than 3 was considered low.
