Summary View help for Summary
This study is part of the Seek, Test, Treat and Retain (STTR) Collaboration Project that involved over twenty studies in the fields of HIV and drug abuse. All studies were independently developed, but were chosen for the collaboration because they focused on one or more steps of the HIV treatment cascade: Seek, Test, Treat and Retain. As part of STTR Collaboration Project, the studies were grouped into Criminal Justice-related studies and Vulnerable Population-related studies. The data collected by these studies included twelve common domains (e.g., Demographic characteristics, Mental Health) in each of which a shared questionnaire or instrument was taken up by the studies and adapted to fit the study.
The Testing & Linkage to Care 'TLC_IDU' study aimed to integrate STTR elements to the base Government of Kenya (GoK) program, including rapid CD4 cell count testing, ART treatment support using peer case support, and evaluation of community viral load. TLC_IDU addressed a most at-risk population (MARP) by focusing on Nairobi and coastal Mombasa (including Malindi), where most injecting drug users (IDU) in Kenya reside. Data was collected at baseline and at five semi-annual follow-ups.
