aAdjusted odds ratios (OR) were obtained from multilevel hierarchical logistic regression models after adjusting for the effects of the following covariates: patient characteristics (age, gender, race, marital status, VA service connection, homelessness, schizophrenia diagnosis, whether last encounter was inpatient, number of medical comorbidity diagnoses) and site characteristics (outpatient clinic status, facility size, and total number of patients on the original list). These models considered patients clustered within sites, and sites are nested within VISNs.
