Synthesis: International perspectives on healthcare for people with intellectual and developmental disabilities

Background
The organization of healthcare for people with intellectual and developmental disabilities (IDD) varies across countries. Each country has developed unique practices embedded in their historical and organizational context. Understanding and sharing these practices across borders facilitates mutual understanding about healthcare needs of people with IDD and facilitates the adoption of effective strategies in other countries.

Aim
To provide a synthesis across the country-specific papers in the JPPID special edition and thereby identify underlying trends, challenges, and best practices in healthcare for people with IDD.

Methods
The papers in this special edition, which describe the organization of healthcare for people with IDD in 13 countries, were qualitatively analyzed using thematic content analysis, focusing on general characteristics, history, and context, organization of healthcare for people with IDD, challenges, and best practices.

Results
Each paper described a specific national history of evolution of healthcare for people with IDD, but our analysis showed that countries face similar challenges in healthcare for people with IDD. These challenges cover (1) access to healthcare, (2) quality of healthcare, (3) implementation, and (4) visibility of people with IDD. Consequently, people with IDD continue to face significant health disparities. Several best practices have been developed, ranging from making mainstream healthcare more accessible and suitable to providing specialized services, and advocating and raising awareness.

Conclusions
This synthesis is the first paper to include perspectives on healthcare for people with IDD across 13 countries. We identified that, despite differences in context, countries face similar challenges in improving healthcare for people with IDD. International collaboration and networking can provide essential tools in reducing health disparities that people with IDD face, starting with the challenges identified in this synthesis. This will require effort to especially include low- and middle-income countries.
