Background and study aims
HIV remains a significant public health issue in Indonesia, particularly among key populations such as men who have sex with men (MSM), transgender people, and sex workers. Early detection and treatment of acute HIV infection (AHI) can reduce transmission and improve long-term health outcomes. This study aims to evaluate a new approach to HIV screening, diagnosis, and treatment, integrating advanced diagnostic tools and digital behavioral interventions to improve HIV care in Indonesia.
Who can participate?
The study targets individuals at high risk of HIV who are seeking HIV testing services at participating sexual health clinics. This includes MSM, transgender people, sex workers, and other key populations at increased risk of HIV exposure.
What does the study involve?
Participants will undergo an enhanced HIV screening process, including a risk assessment and HIV-PCR testing. Those diagnosed with HIV will be offered assisted partner notification services and immediate treatment start. A digital behavioral intervention at CekUpYuk.id will be provided to promote HIV prevention, risk assessment and testing.
What are the possible benefits and risks of participating?
Benefits:
1. Early detection of HIV, enabling prompt treatment and rapid viral suppression.
2. Improved access to care and support services.
3. Contribution to public health efforts to reduce HIV transmission.
Risks:
1. Confidentiality risks, although strict data protection measures are in place.
Where Is the study run from?
The study is being conducted at high-volume sexual health clinics in Jakarta and Bali, Indonesia, in collaboration with local and international research institutions.
When is the study starting and how long is it expected to run for?
September 2022 to August 2025
Who is funding the study?
The study is funded by the Medical Research Council, UK Research and Innovation, and is sponsored by the University of Oxford (UK).

| Scientific title | Indonesia intervention study to test & treat people with acute HIV infection (INTERACT) |
| Study acronym | INTERACT |
| Study objectives | The principal overarching research question of the INTERACT project is to evaluate whether implementing a patient-centered care pathway to test and treat acute HIV infection (AHI), coupled with a tailored digital behavioural intervention, can curb the rapidly growing HIV epidemic among key populations in Jakarta and Bali. The INTERACT project aims to answer the following key scientific questions: 1. What is the effectiveness/yield of implementing an AHI clinical pathway? 1.1. Is a risk/symptom screening score an effective method for detecting AHI among men who have sex with men (MSM) and other key populations in Jakarta and Bali? Can the score be locally optimized? 1.2. Do same-visit delivery of diagnosis and immediate initiation of antiretroviral therapy (ART) shorten the time to reaching undetectable viral load? 1.3. What are the factors associated with AHI diagnosis and immediate ART failure/success? 2. What is the uptake/adoption, acceptability and feasibility of an AHI clinical pathway? 2.1. Does the clinical pathway lead to an increased number of individuals and their sexual partners tested for and diagnosed with AHI, and starting immediate ART during AHI, compared to the usual care? What is the uptake, feasibility, and acceptability of the clinical pathway? 2.2. Are AHI patients willing to start ART on the day of diagnosis and adhere to immediate ART? And what are the barriers and facilitators to immediate ART start? 2.3. Can we identify HIV-negative, high-risk populations for enhanced sexual health counselling, and preparation for future PrEP introduction? 3. What is the potential impact of implementing an AHI clinical pathway on curbing the HIV epidemic in Indonesia? 3.1. How many infections and deaths would be averted and quality-adjusted life-years (QALYs) gained in various intervention scale-up scenarios? 3.2. What are the incremental costs or cost savings of those possible scenarios? |

| Health condition(s) or problem(s) studied | Screening of individuals attending a sexual health clinic at risk of HIV acquisition for acute HIV infection (AHI) |
| Intervention | 1. Implementing an optimally sensitive AHI screening approach through a client self-completed risk assessment (“AHI Risk Assessment”), coupled with HIV-PCR diagnostic testing (sequential to and additional to current local standard-of-care HIV Ag/Ab based testing). 2. Strengthening HIV care cascades by same-day delivery of HIV-PCR test results, immediate offer of ART in newly HIV-diagnosed persons, and monitoring HIV-RNA at 3 and 6 months after ART initiation to ensure response and adherence to treatment. 3. Implementing an evidence-based digital behavioural intervention tool, tailored to the wider target population at high risk of HIV, through media platforms, to promote uptake/adoption of HIV prevention, testing and the AHI clinical pathway. |
