PositiveLinks: mHealth for DC Cohort
NCT04998019 · View on ClinicalTrials.gov ↗
Study Summary
To achieve the end of the HIV epidemic, concerted efforts will be needed to address the HIV care continuum, including improving retention in care (RIC) and viral suppression (VS) among persons with HIV (PWH). In the U.S., less than 50% of PWH are RIC and even fewer are VS. Studies have shown that these PWH have poorer clinical outcomes and are at risk of transmitting HIV to others, hence the need for innovative solutions to improve retention in care and subsequent viral suppression. Theory-based mHealth interventions have been shown to be promising in reaching these at-risk groups and improving HIV-related outcomes. PositiveLinks is a clinic-deployed mHealth platform that includes patient and provider smartphone apps, a web portal for clinic staff and providers to manage patient cohorts, an online implementation guide, and a learning management system to train and certify clinic staff. It has theory-based features including daily queries of adherence, mood, and stress, graphical feedback for self-monitoring, secure messaging with staff, appointment reminders, anonymized peer support, information resources, and document upload capability to support insurance re-enrollment. A 12-month prospective study in poorly retained PWH found that PL increased RIC and VS, with app use related to benefit as well as improved social support and stigma. PL is a promising existing mHealth tool for PWH, yet its efficacy has not been tested in a randomized trial, nor in urban populations. The investigators will test the efficacy of PositiveLinks to improve RIC and VS among a cohort of PWH in a high HIV prevalence city of Washington, DC. Participants will be identified from the DC Cohort, a longitudinal prospective cohort of PWH receiving HIV care at 15 clinics in DC. First, the investigators will conduct formative research to assess the feasibility, acceptability and usability of PositiveLinks among this urban cohort and conduct subsequent adaptations based on these findings.

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT04998019
The ClinicalTrials.gov registry entry for NCT04998019 describes a study currently listed as completed. It is categorized as NA, which is the standard way researchers label where a study sits along the investigational pathway from early safety work through later efficacy and post-marketing evaluation. The registered enrollment target is 682 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is George Washington University, which has 134 total studies on file at ClinicalTrials.gov, and sponsors are the parties responsible for study design, oversight, and regulatory filings.
The record links to 1 condition, with HIV/AIDS appearing as the primary indexed condition, and to 1 intervention — of which PositiveLinks is the first listed. Interventions can include drugs, devices, procedures, behavioral programs, or observational arms, and each is tracked as a separate registry field so that downstream queries can filter accurately. When a trial lists multiple interventions, it usually reflects a multi-arm design or a comparison protocol rather than a single treatment being tested in isolation. The brief summary published in the registry is the clearest source of protocol intent and should be read before drawing conclusions from any sidebar tags.
Geographic footprint matters for practical reasons: NCT04998019 reports 13 study locations spanning 1 distinct geographic area — top geographies include District of Columbia. A larger site network tends to correlate with broader recruitment capacity, but it does not imply anything about study quality, and site-level enrollment status can diverge from the overall registry status shown above. Every data point on this page comes from the public ClinicalTrials.gov dataset and is reproduced here for reference only; it is not a medical recommendation, an endorsement of the sponsor, or an invitation to enroll. Verify current status, eligibility criteria, and contact details directly at ClinicalTrials.gov, and discuss any participation decision with your own healthcare provider.
