Work package	Key populations	Index testing	Coupons survey	Cost study	Modelling
Specific objectives	- Identify factors favouring and limiting the introduction of HIVST in the health care system (public and community) and primary and secondary distribution of HIVST kits to key populations. - Analyse perceptions, attitudes, ownership, experience and living with HIVST - Analyse the social effects of HIV prevention. - At the individual, collective and care system levels, in each of the three countries and among the different key populations, take into account the socio-cultural and political contexts that differ from one country to another and from one key population to another.	- Describe how HIV care services and caregivers integrate the proposal of HIVST for partners of PLHIV. - Study how PLHIV negotiate issues around the HIVST proposal to their partner. - Analyse the perceptions, uses and modalities of use of HIVST by PLHIV partners, as well as the impact of the use of HIVST on the relationship between screening and risk. - Identify the individual, conjugal and social impacts of the HIVST.	- Document the socio-behavioural profile and screening history of HIVST users. - Identify the care trajectories of these HIVST users following a reactive or indeterminate self-test. - Provide an empirical estimation of certain parameters used by the Modelling WP.	- Estimate the incremental costs of providing HIV kits by country and by delivery channel based on observed programme costs. - Compare the costs of HIV testing and counselling with other HIV testing and counselling approaches for the same populations in ATLAS countries. - Model the costs of scaling up (regionally and/or nationally) a combination of medium (3–5 years) and long-term HIV HIVST delivery models for budget planning purposes. - Compare the costs with the expected epidemiological impacts (Modelling WP) to estimate the cost-effectiveness of these scale-up scenarios.	- Identify those most likely to acquire and transmit HIV and identify delays in testing and diagnosis. - Estimate the population-level impact of the introduction of HIVST in the three ATLAS countries, (i) at the scale achieved by the ATLAS programme and (ii) within the framework of possible scenarios for scaling up. - Estimate the cost-effectiveness of these scale-up scenarios and conduct a sensitivity analysis to determine the conditions and factors that influence cost-effectiveness.

Specific objectives

- Identify factors favouring and limiting the introduction of HIVST in the health care system (public and community) and primary and secondary distribution of HIVST kits to key populations.

- Analyse perceptions, attitudes, ownership, experience and living with HIVST

- Analyse the social effects of HIV prevention.

- At the individual, collective and care system levels, in each of the three countries and among the different key populations, take into account the socio-cultural and political contexts that differ from one country to another and from one key population to another.

- Describe how HIV care services and caregivers integrate the proposal of HIVST for partners of PLHIV.

- Study how PLHIV negotiate issues around the HIVST proposal to their partner.

- Analyse the perceptions, uses and modalities of use of HIVST by PLHIV partners, as well as the impact of the use of HIVST on the relationship between screening and risk.

- Identify the individual, conjugal and social impacts of the HIVST.

- Document the socio-behavioural profile and screening history of HIVST users.

- Identify the care trajectories of these HIVST users following a reactive or indeterminate self-test.

- Provide an empirical estimation of certain parameters used by the Modelling WP.

- Estimate the incremental costs of providing HIV kits by country and by delivery channel based on observed programme costs.

- Compare the costs of HIV testing and counselling with other HIV testing and counselling approaches for the same populations in ATLAS countries.

- Model the costs of scaling up (regionally and/or nationally) a combination of medium (3–5 years) and long-term HIV HIVST delivery models for budget planning purposes.

- Compare the costs with the expected epidemiological impacts (Modelling WP) to estimate the cost-effectiveness of these scale-up scenarios.

- Identify those most likely to acquire and transmit HIV and identify delays in testing and diagnosis.

- Estimate the population-level impact of the introduction of HIVST in the three ATLAS countries, (i) at the scale achieved by the ATLAS programme and (ii) within the framework of possible scenarios for scaling up.

- Estimate the cost-effectiveness of these scale-up scenarios and conduct a sensitivity analysis to determine the conditions and factors that influence cost-effectiveness.
