Using HIV Surveillance and Clinic Data to Optimize Data to Care Efforts in Community Health Centers in Massachusetts: The Massachusetts Partnerships for Care Project.

Background: We describe Data to Care processes of the Massachusetts Partnerships for Care (MA P4C) project and identify factors associated with engagement, retention, and viral suppression outcomes. Methods: The Massachusetts Department of Public Health and participating community health centers generated lists of patients not in care based on a temporal gap in laboratory results, missed clinic visits, and provider concern regarding engagement. The Massachusetts Department of Public Health and community health centers reviewed the lists monthly and identified out-of-care patients in need of linkage or re-engagement. Results: Between October 2015 and June 2017, of 1418 patients potentially out of care, 83 (5.9%) were confirmed to be out of care. Forty-four of those out of care (53%) received services or were re-engaged in care within 90 days, 45 (54%) were retained in care, and 40 (48%) were virally suppressed. The odds of being re-engaged or retained were lower for patients who were 6 months out-of-care (vs. those newly diagnosed). Patients with an AIDS-defining condition had increased odds of retention and viral suppression. The odds of viral suppression were reduced for patients who reported exposure categories other than men who have sex with men and were younger (30-49 years vs. >= 50 years). Conclusions: Although rates of re-engagement, retention, and viral suppression were low, the MA P4C Data to Care procedures provided a means for accurate ascertainment of out-of-care status. Future Data to Care programs should investigate the factors that contribute to disengagement from care.
