Purpose. The CoNNECT Project enables comparative effectiveness research on mental health, behavioral health, and substance use in primary care. CoNNECT tracked two main elements: (1) the number of patients identified with a comorbid mental health and physical health diagnosis; (2) the number of patients who initiate treatment secondary to a mental health diagnosis. CoNNECT created the capacity to build a base for mental health in primary care comparative effectiveness research using electronic connectivity to generate retrospective and in time prospective clinical data.Data Access. CoNNECT data are not available from ICPSR. The data from this study are hosted at DARTNet.

Current DARTNet practices are located in 12 states and utilize seven different EHRs. The largest concentration of practices is in Texas where two larger group practices are members. Other large member practices are located in Illinois, Pennsylvania, and New York. Other medium to large groups of practices are in Colorado, North Carolina, Virginia, and Minnesota, with small practices located in Colorado, Texas, Missouri, Arkansas, North Carolina, Vermont, Pennsylvania, and New Jersey. The Texas practices include a large Hispanic population mirroring that state's demographics (30-40 percent of the patient population in these practices). The Colorado practices have a smaller Hispanic population in the 10-15 percent range. The North Carolina practices include the highest percentage of African Americans but this is still less than 20 percent of the patient population of these practices. Several of the largest group practices all have substantial Medicare populations ranging from 30 percent to over 60 percent.
