Coef, Coefficient; FM, family medicine; PCMH, Patient-Centered Medical Home; PCA, Practice Culture Assessment; SE, standard error.
↵* Model 1 includes basic practice characteristics, model 2 added one combination of PCA scale (Change culture and chaos), and model 3 tested the other combination of PCA scales (Work culture and chaos). Change culture and work culture were tested in separate models to reduce multicollinearity; SE, standard error.
