Kentucky Communities and Researchers Engaging to Halt the Opioid Epidemic (CARE2HOPE)
The proposed project will employ community/academic partnerships to build effective, evidence-based, community-grounded public health responses to combat the intertwined epidemics of heroin and non-medical prescription opioid injecting, overdoses, and HCV, and imminent HIV outbreaks, in 12 of the hardest hit rural counties in the US. Located in Central Appalachian Kentucky, 10 of the 12 counties are in the top 5% for HIV/HCV vulnerability in the US.

Developing an Overdose Prevention Mobile Application
Unintentional poisoning, primarily from drug overdose, is the leading cause of injury-related death among Americans. The Appalachian region has been disproportionately burdened by overdose fatalities and obstacles to overdose prevention have included: (1) legal barriers to naloxone access and too few people trained in overdose prevention, (2) long emergency response times and fear of arrest for calling 911 to report overdoses, and (3) low substance abuse treatment uptake. This proposal aims to address these three factors which have contributed to the overdose epidemic in this region through the development of a novel mobile app.

Combining social network, spatial, and phylogenetic approaches to identify new HIV infections.
HIV transmission rates are ~3.5 times higher among those who are HIV-infected but unaware of their status, compared to those who are aware, and innovative strategies are urgently needed to find HIV-infected individuals who are not yet linked to care and others who are at increased risk for acquiring HIV. Current strategies to identify new HIV infections use social network, spatial, and phylogenetic approaches, but combining these three approaches is rare. This project will develop new analytic methods to combine these three types of data and analyses will inform the development novel multi-level and targeted strategies to identify previously undiagnosed HIV infections and deliver prevention interventions to those most at risk for acquiring HIV

Semi-Automated Processing of Interconnected Dyads Using Entity Resolution (SPIDER)
The overarching aim of this SBIR project is to develop and verify a new software system that will assist researchers in more rigorously constructing social networks. The software, Semi-automated Processing of Interconnected Dyads using Entity Resolution (SPIDER), will enable efficient, semi-automated network construction using a library of robust, statistically rigorous algorithms, rich desktop-based annotation tools, and secure web-based technologies. SPIDER will allow for multi-disciplinary utility in studies using varying designs and will include innovative features that respond to emerging methodological trends in HIV/STI research.
