The World Health Organization (WHO) has issued a call for case studies on integrated service delivery for HIV, tuberculosis (TB), hepatitis, and sexually transmitted infections (STIs). The aim is to gather real-world examples of how these services are organized, delivered, and coordinated across different settings. The findings will help illustrate practical approaches and provide lessons to guide the design and implementation of integrated service models.
Countries are increasingly adopting integrated approaches that combine HIV, TB, hepatitis, and STI services with other essential health services aligned with primary health care. These models aim to improve access, continuity, efficiency, and quality of care by organizing services around people’s needs while addressing disease-specific requirements.
Despite this, implementing integrated approaches at the point of care remains challenging. Many services are still delivered through disease-specific workflows, financing mechanisms, and reporting arrangements, with limited guidance on coordination. Additional barriers include workforce shortages, gaps in diagnostics and commodities, and fragmented digital systems, all of which limit continuity and quality of care.
To support evidence-based guidance on integrated service delivery, WHO invites submissions of case studies describing practical experiences at facility, community, or outreach levels. Case studies should describe the integration of at least one of the targeted conditions and may also include integration across multiple diseases, other health services, or non-health services addressing social, legal, or economic factors.
Submissions should include context and setting, services delivered, target populations, points of integration along the care continuum, and the service delivery settings. They should also describe how care is organized and delivered, including referrals, follow-up, continuity, and the roles of different providers. Information on task-sharing, team-based approaches, enablers, barriers, lessons learned, outcomes, and adaptations to local contexts is encouraged.
Eligible case studies must describe models that have been implemented or piloted, focusing on service delivery at the point of care rather than high-level policy reforms. Facility-based, community-based, and outreach models are all welcome.
Submissions should be sent to NSP4HTH@who.int
by 1 May 2026, 23:59 CEST. Questions about scope or content can be directed to parwatic@who.int
. Case studies can be submitted in any of the WHO working languages: Arabic, Chinese, English, French, Russian, and Spanish.
