a
All data in table are from Medicaid records and are n (%) unless otherwise indicated.
b
P value comparing intervention versus control participants calculated by using Rao-Scott χ2 test adjusted for cluster randomized design (categorical variables) or t tests for continuous variables.
c
Other races include Native Hawaiian/Pacific Islander, Asian, and American Indian/Alaska Native.
d
The comorbidities score is from Medicaid’s Clinical Risk Group weighting system (http://www.ncbi.nlm.nih.gov/pubmed/14713742), which assigns scores to patients on the basis of a prediction of resources needed to address their conditions. For example, a weight of 3 indicates that a patient is expected to spend 3 times the time of the average patient.
