Multivariable logistic regression analyses showing the association between care density and outcomes for (a) the entire cohort and patients with (b) CHF, (c) COPD, and (d) DM. The comparison group contains patients in the lowest tertile of care density. Analyses are adjusted for age, gender (except breast and cervical cancer screening), insurance plan and product type, comorbidity (ADGs), number of outpatient visits, number of providers, whether the patients saw a PCP, and the percentage of visits with the usual provider of care.
(Note: See Appendix Table 4 for detailed logistic regression results.)
