Differentiated Service Delivery (DSD)

AIM: To ensure the scale up of differentiated service delivery for HIV to improve access to and quality of prevention, testing, treatment and care services for people living with and vulnerable to HIV and maximize synergies with other health areas.

"The amount of time we spend at the health facility in the queues – a queue for triage, a queue for the nurse, a queue at the pharmacy and a queue for the labs – it's too much time. I want to come to the facility only twice a year ... I have a life to live." – Patricia Asero Achieng, Kenya

With significant global normative guidance supporting the adoption of differentiated service delivery (DSD) for HIV and continued scale up, national governments and implementers need critical and timely operational guidance on how to scale up quality DSD. The IAS Differentiated Service Delivery programme addresses these gaps in HIV service delivery by:

  • Continuing to advocate for DSD while expanding available tools to develop guidance to further support DSD uptake
  • Strengthening engagement with, and within, countries and communities
  • Leveraging global best practices, tools and evidence

A key component of this work is www.differentiatedservicedelivery.org – the go-to resource for implementing quality DSD for HIV. To highlight latest research, new innovative tools and upcoming events, the IAS DSD programme publishes a quarterly newsletter. Sign up to the DSD newsletter.


Since 2015, the World Health Organization has endorsed a differentiated service delivery approach to providing HIV services to support reaching the Joint United Nations Programme on HIV/AIDS (UNAIDS) 95-95-95 targets by 2030. Differentiated service delivery has been defined as “a client-centred approach that simplifies and adapts HIV services across the cascade, in ways that both serve the needs of people living with HIV better and reduce unnecessary burdens on the health system”. The IAS, through the ongoing work of DSD, is committed to supporting the quality scale up of DSD for HIV through catalysing country and community advocacy and amplifying global best practices, tools and evidence to effectively reach the 37 million people worldwide in need of high-quality life-saving HIV care.
