National Rapid TLC: Testing and Linkage to Care

Overview

The goal of this cross-sectional study is to learn if the GeneXpert system is a practical system for HIV and STBBI testing in community-based organizations and health clinics. The study involves a clinical trial to learn if the HIV-1 Qual XC test works to identify HIV in near-patient settings. The main questions it aims to answer are to create a near-patient testing model for testing and treating patients in a single visit, and to learn if the HIV-1 Qual XC test works to accurately detect HIV in patients. Patients who come to study sites to ask for HIV or STBBI testing will be given the option to participate in the study. Those who agree with provide samples for the tests of their choice and answer survey questions before and after their tests are completed. Those who participate in the clinical trial will have a blood sample sent to provincial labs to compare the results to the HIV -1 Qual XC test. Follow-up visits will be done at 1,3 and 6 months to see if patients completed treatment and/or remained connected to care.

A nationwide test, treat, and connect intervention will be implemented to reach 2,500 individuals attending clinics for routine sexually transmitted and blood-borne infection (STBBI) testing. The intervention will provide opportunities for immediate treatment and culturally appropriate care for hepatitis C virus (HCV), chlamydia, gonorrhea, and HIV. The Xpert HIV-1 Qual XC test performance evaluation will be conducted in community-based point-of-care (POC) settings across Canada to reach up to 1,000 individuals presenting for HIV testing, including those with suspected HIV infection, those at high risk of HIV acquisition, and individuals known to be living with HIV. The evaluation will provide opportunities for newly diagnosed individuals to receive immediate treatment and culturally appropriate HIV care. Critical to the success of this initiative is the engagement and support of people with lived experience, peer navigators, and leaders from community-based organizations in all aspects of the work through shared leadership, collaboration, and joint decision-making. This approach will help address barriers to testing, diagnosis, and care experienced by underserved and undiagnosed populations in inner-city, remote, rural, and isolated communities. All participating sites will use Health Canada-approved rapid antibody point-of-care tests to screen for HIV, combined HIV/syphilis, and/or HCV. All investigational and licensed molecular point-of-care testing (POCT) devices utilize the GeneXpert (GX) Instrument System to automate and integrate sample preparation, nucleic acid extraction, amplification, and target sequence detection in simple and complex specimens using real-time reverse transcription polymerase chain reaction (RT-PCR). The system consists of an instrument, a personal computer, and preloaded software for performing tests and reviewing results. Testing requires the use of single-use disposable GeneXpert cartridges containing the RT-PCR reagents and supporting all RT-PCR processes. The self-contained cartridge design minimizes the risk of cross-contamination between samples. The Xpert HIV-1 Qual XC assay includes reagents for the detection of HIV-1 total nucleic acids, as well as an internal control to verify adequate target processing and monitor for the presence of inhibitors during the reverse transcription and PCR reactions. The Probe Check Control (PCC) verifies reagent rehydration, PCR tube filling within the cartridge, probe integrity, and dye stability.
