About
The PATH for Triples (PFT) Study is an effectiveness trial comparing a nurse health navigator (NHN) model for HIV+ persons with severe mental illness and substance abuse (i.e., triply diagnosed) with Treatment as Usual (TAU). The team completed a Phase II trial of the nurse health navigator model for HIV+ persons with severe mental illness that showed the intervention was effective. The investigators are now testing the intervention in a real world setting with patients recruited from psychiatric and substance abuse inpatient units in Philadelphia using a longitudinal design. The intervention is set up as a cascade where non-adherent patients receive additional visits from the study nurses. It is hypothesized that patients assigned to the NHN will have better medication compliance, reduced viral loads and improved CD4 counts compared to patients assigned to TAU. It is also hypothesized that the PFT intervention group will be more cost effective compared to TAU. This group of triply diagnosed patients are at very high risk of negative health outcomes and secondary transmission of HIV and, therefore, the study is of high public health significance.
Full description
In response to PA-12-281, HIV/AIDS, Drug Use, and Vulnerable Populations in the US (R01), we are conducting an effectiveness trial among persons triply diagnosed (mental illness, substance abuse, HIV) recruited from inpatient psychiatric units in Philadelphia. Despite general recognition that persons with serious mental illness (SMI) are at heightened risk to contract and transmit human immunodeficiency virus (HIV), systematic HIV testing in mental health settings is rare. Using discarded blood samples over a six-month period, our research team found in excess of 10% HIV seroprevalence in two inpatient psychiatric units in Philadelphia. We argued then that HIV testing should be routinely conducted in those settings. In a five-year longitudinal effectiveness trial, we will identify HIV positive SMI inpatients through rapid testing. Those who are newly diagnosed or who were previously diagnosed but not currently engaged in HIV treatment and who also are substance using will be offered an opportunity to participate in a randomized community trial. Previously, we have conducted a Phase II trial of PATH for Positives (PFP) in which we observed broad and far-reaching effects of an intervention utilizing a nurse health navigator (NHN) model for HIV+ SMI clients. The current study builds on what we learned previously to provide a nurse health navigator (NHN) model as integrated treatment of the targeted individuals in "real world" conditions and to monitor the implementation of PATH for Triples (PFT). The target population is arguably among the highest risk patient populations for poor treatment outcomes. Based on past experience, we expect to enroll about 75% of those eligible on a rolling basis, or ~240 participants who will then be randomized. This will yield ~120 PFT and ~120 Treatment as Usual (TAU) participants over a 36-month recruitment window before attrition. A similar population in PFP resulted in a 17% attrition rate, so we estimate complete data for at least 75% of participants resulting in a complete dataset of ~180 participants (90 PFT, and 90 TAU). PFT participants will receive NHN services for 6 months. Data will be collected at baseline, 3, 6, and 9 months for each participant. Participants will be followed longitudinally for an additional 3 months post intervention to measure any decay of the intervention after it is withdrawn. Experimental participants will begin PFT while still receiving inpatient services and the project nurses will participate in discharge planning and facilitate linkage to Mental Health (MH), Substance Abuse (SA), and Infectious Disease (ID) care in the Philadelphia community. The NHN will also meet at least weekly with the experimental participants to implement the adherence component of PFT using approaches tailored to the communication and comprehension of the person that includes memory aids, education regarding side effects and other treatment aspects, engagement with participants' social networks and treatment providers, and active community outreach. We expect better retention in treatment for PFT participants and improvement in other outcomes including viral load, CD4, indicators of psychological and social functioning, and cost effectiveness.
