Brief Summary
The community-based ART delivery (CAD) model will build on the existing framework to engage community action, operationalized in the current Global Fund-supported project. Community Action Workers (CAW), who are assigned to ART centers and conduct outreach work, are well-suited to administer CAD scheme. KHANA and the project partners all have implementation roles in the Global Fund-supported project and established working channels with the CAW. While the previous experiences suggest the CAD model's effectiveness, implementing it in Cambodia requires adaptation to its specific local context. The proposed project will be implemented as an implementation study in nine ART sites and supported by a concrete evaluation plan. KHANA Center for Population Health Research will lead the research component. The project has three strategic areas and corresponding deliverables as follows: A. The development of a locally-fitted model: bringing ART closer to the people living with HIV B. The research: formulation, evaluation, documentation, and dissemination of the evidence, knowledge, and lessons learned C. The scale-up: advocacy for the SOP development to replicate/scale-up the CAD model The project will benefit a wide range of stakeholders. The approximately 2,000 ART clients enrolled in the nine selected clinics will face less cost, time, and discrimination, which will also benefit their families. The clinics will have a reduced workload on site, and they would be able to improve the quality of care for the visiting clients. The Cambodian health system will obtain a CAD model tailored to the country's local context and develop Standard Operating Procedures for the scheme with readily involved stakeholders. The scale-up of the model will benefit all other ART clinics and clients in the country. The 36-months project starting from June 1, 2019, will include six months of start-up and baseline assessments, 24-month intervention, and six-month evaluation.

Outcome Measures
Primary Outcomes (4)
Percent of people living with HIV with viral suppression
Viral load At least 90% of participants in intervention arm will have a viral load \<1000 RNA copies/mL by the endline of the intervention
24 months after the intervention started
Percent of people living with HIV who remained in HIV care and treatment
At least 90% of participants in the intervention will be retained in care and treatment 12 months after the treatment started
24 months after the intervention started
Percent of people living with HIV with good adherence to ART
At least 90% of the participants in the intervention will report good adherence to ART at the endline.
24 months after the intervention started
Percent of healthcare providers at ART clinics who reported reduced workload
Workload at ART clinics will be self-reported by health care workers providing ART services at the clinics. The investigators hypothesize that a significantly higher proportion of health care providers at ART clinics under the CAD intervention arm will agree that their workload has been reduced at endline compared to baseline.

Study Arms (2)
Community-based ART delivery (CAD)
EXPERIMENTALThe CAD model intervention will take place for 24 months. A total of 2000 registered stable people living with HIV will form into the CAD group. The investigators have developed the implementation guide, monitoring tools, quality assurance checklist, and lists of people living with HIV in selected ART clinics for the CAD model intervention. The first step will be to extract the data disaggregated by gender, age, and type of sub-populations, including adolescents, female entertainment workers, men who have sex with men, transgender women, and people who use drugs from the national database using the definitions introduced by the WHO. Once the list is completed with patient ART codes, a consultative meeting combined with the project orientation will be convened. Providers from the selected ART clinics and implementing partners at each site will divide stable people living with HIV into their respective groups based on the ART sites.
ART multi-month dispensing (MMD)
ACTIVE COMPARATORA total of 2000 registered stable people living with HIV will form into the control group and received standard services under the MDD model. The control-arm participants will visit the ART clinics and collect their ARVs from the facility-based staff.
Interventions
The frontline workers to implement the CAD model intervention will be people living with HIV recruited from the community who will plays roles as CAWs. The CAWs will receive intensive training, coaching, and mentoring from their respective ART clinics and implementing partners' field staff on ARV dispensing, drug storage, patient's vital sign assessment and recording, HIV education and counseling, medication adherence, referral systems, mental health, stigma and discrimination, and sexual and reproductive health of people living with HIV. To closely monitor the work of the CAWs, a respective ART clinic team, consisting of an ART counselor and a physician, will be tasked to conduct regular supervision along with the program team of the implementing partners to the community groups at least once a month in the first six months. After the six months, supervisory visits will be extended to once every two months.
The control arm participants will receive routine services under the MMD model based on standard community-based prevention, care, and support practices in Cambodia. The NCHADS has introduced MDD in all ART sites across the country. However, so far, not all ART sites currently operate the MMD. The MMD is designed to help ART service providers implement MMD for eligible patients-that is, patients whose condition is determined to be stable-which will reduce the need for frequent visits and providers' workload. Stable people living with HIV receive care and support from counselors and ARVs at the clinics every four to six months.
Eligibility Criteria
You may qualify if:
- Receiving ART for at least one year.
- No adverse drug reactions or ARV drug interactions requiring regular monitoring.
- No suspected or confirmed tuberculosis, no other opportunistic infections, and not on any prophylaxis.
- Not pregnant/breastfeeding (for women).
- Having a good understanding of lifelong treatment and adherence to the medication.
- Presenting with evidence of treatment success: two consecutive undetectable viral load measures (or, in the absence of viral load monitoring, CD4 counts above 200 cells/mm3 and objective adherence measure).
- Aged ≥15 years.
- On the first-line ARV regimen.
You may not qualify if:
- Unstable people living with HIV as defined above
- Mobile populations
