HIV testing in jails has provided public health officials with the opportunity to not only identify new cases of HIV but to also reestablish contact with previously diagnosed individuals, many of whom never entered care following diagnosis or entered care but then dropped out. The presence of inmates throughout the HIV/AIDS continuum of care suggests that jails can play a strategic role in engaging persons living with HIV and AIDS in care. In order to be successful in structuring HIV/AIDS programs in jails, health care and correctional officials will be well-served to: (1) understand the HIV/AIDS continuum of care from the standpoint of engagement interventions that promote participation; (2) be aware of jail, community, and prison interventions that promote engagement in care; (3) anticipate and plan for the unique barriers jails provide in implementing engagement interventions; and, (4) be creative in designing engagement interventions suitable for both newly and previously diagnosed individuals.

Linkage, engagement, retention and adherence to care are necessary steps along the HIV care continuum. Progression through these steps is essential for control of the disease and interruption of transmission. Identifying and re-engaging previously diagnosed but out-of-care patients is a priority to achieve the goals of the National HIV/AIDS strategy. Participants in the EnhanceLink cohort who were previously diagnosed HIV+ (n = 1,203) were classified as not-linked to of care and non-adherent to medication prior to incarceration by self report. Results based on multivariate models indicate that recent homelessness as well as high degrees of substance abuse correlated with those classified as not-linked to care and non-adherent to medications while having insurance was associated with being linked to care and adherent to care. The majority of detainees reported being linked to care but not currently adherent to care confirming that jails are an important site for re-engaging HIV+ individuals.
