Yes, global public health systems can and often do use both the DSM and ICD frameworks for autism diagnosis. While the DSM (Diagnostic and Statistical Manual of Mental Disorders) is widely adopted in research and clinical settings, the ICD (International Classification of Diseases) is the official classification used by most health systems worldwide. Many clinicians are trained to navigate both systems, allowing for flexibility in diagnostic reporting and international collaboration.

How Both Healthcare Systems Work Together 

In global health contexts, both manuals can complement each other. Here are key ways they are applied in practice: 

Standardised Language Across Borders 

Using both DSM and ICD ensures healthcare providers share a common diagnostic language, improving communication in international research and treatment planning. 

Adaptation to Local Healthcare Systems 

Some countries adopt ICD for official reporting while clinicians still refer to DSM criteria for detailed case formulation, ensuring both administrative compliance and clinical depth. 

Facilitating Global Research 

By recognising both systems, studies can include participants from countries using either framework, improving the scope and applicability of autism research. 

Supporting Healthcare Systems with Diverse Training 

In regions where professionals have varied training backgrounds, using both systems helps bridge knowledge gaps and ensures consistent autism standards. 

Summary 

In short, global public health can benefit from using both DSM and ICD for autism diagnosis, as this approach strengthens collaboration, supports accurate reporting, and ensures inclusivity in research and healthcare delivery.
