Table I. Unadjusted and adjusted hospital-level outcomes compared across hospital groups.

	All hospitals (n = 43) median (IQR)	Group A hospitals (n = 4) median (IQR)	Group B hospitals (n = 19) median (IQR)	Group C hospitals (n = 16) median (IQR)	P value^*
Unadjusted LOS (d)	3.21 (2.78, 3.79)	2.87 (2.19, 3.15)	3.29 (2.72, 3.85)	3.34 (3.06, 3.66)	.19
Adjusted LOS (d)^†	3.28 (3.03, 3.50)	3.39 (2.67, 3.76)	3.24 (2.90, 3.41)	3.32 (3.18, 3.59)	.34
Unadjusted 30-d readmission rate	8.4 (6.8, 9.9)	4.9 (4.1, 6.7)	8.9 (8.3, 11.6)	6.9 (6.6, 9.7)	.003
Adjusted 30-d readmission rate^†	8.5 (7.3, 9.3)	7.2 (5.7, 8.7)	9.0 (8.4, 10.5)	7.7 (6.8, 9.2)	.03
Unadjusted pneumonia-associated complications rate	23.1 (18.7, 26.8)	20.2 (15.9, 27.1)	23.8 (18.7, 27.2)	23.1 (19.9, 24.1)	.81
Adjusted pneumonia-associated complications rate^†	23.0 (19.9, 25.7)	22.5 (20.3, 27.4)	22.45 (19.9, 24.4)	24.78 (19.9, 26.2)	.58

Models for LOS and readmission outcomes additionally included pneumonia-associated complications as a covariate.

P value represents comparison of group A, group B, and group C hospital outcomes from generalized linear mixed-effects regression model for LOS and as a binary response in a generalized mixed-effects model with logit link for readmission rate and pneumonia-associated complications rate.
