International Journal Of Mental Health Systems

Overview

The editorial frames the global burden of mental ill-health as a major public health challenge and argues that mental health systems should be designed around the needs and expertise of people with lived experience. It describes fragmented, under-resourced services and presents inclusion, coordination, and continuous learning as central considerations for system development. WHO guidance and related learning-health-system sources provide additional context on governance, routine data, and evaluation.

Background

The article estimates that approximately 1.2 billion people worldwide live with a mental health disorder and reports that projected attributable costs are expected to exceed US$6 trillion by 2030. It characterizes many mental health systems as under-developed, under-resourced, and composed of services with limited integration, contributing to fragmentation, access barriers, and inequities. The editorial emphasizes that care should enhance the lives of people with mental health challenges and their families, and that their experiences should inform system design and evaluation. It distinguishes lived experience from lived experience expertise, which combines experience with knowledge and skills that can be applied to support others and inform services and research.

WHO mental health policy guidance	Highlights governance, routine data collection, and iterative evaluation	WHO guidance, 2025

Key Findings

The editorial identifies the worldwide burden of mental health disorders and related costs as a major challenge for health systems.
It argues that service-user engagement and retention should be understood as responsibilities of services and systems, rather than failures of people whose needs remain unmet.
Lived experience expertise is described as lived experience combined with knowledge and skills that can be applied for others’ benefit; the editorial notes its relevance to research and service development, delivery, and evaluation.
The authors call for lived experience to inform the full system pathway, including research, prevention, access, care delivery, outcome measurement, evaluation, and definitions of success.
The editorial describes mental health services as frequently siloed and insufficiently integrated, with population-level consequences including fragmented care, access obstacles, inequities, and accountability gaps.
Related learning-health-system material describes continuous improvement through coordination of science, informatics, incentives, and culture, while WHO’s 2025 policy guidance highlights governance, routine data collection, and iterative evaluation.

Clinical Implications

The editorial supports involving people with lived experience and lived experience expertise in the design, delivery, and evaluation of mental health services and systems. WHO’s cited policy guidance provides system-level context for governance, routine data collection, and iterative evaluation; the supplied material does not specify clinical interventions or comparative treatment outcomes.

Conclusion

The editorial presents inclusion of lived experience and stronger system integration as central to developing mental health services that respond to population needs. Its account of learning systems and WHO policy guidance situates continuous data-informed evaluation within broader mental health system development.
