Comparative case studies in integrated care implementation from across the globe: a quest for action.

Area of Science:

• Healthcare Delivery and Policy
• Health Services Research
• Implementation Science

Background:

• Integrated care, the coordination of general and behavioral health services, is a promising approach to enhance healthcare delivery and patient outcomes.
• Despite growing international interest, formal guidelines for implementing integrated care across diverse healthcare systems are lacking.
• Successful integrated care implementation is influenced by a complex interplay of factors at multiple levels.

Purpose of the Study:

• To highlight current integrated care implementation efforts through seven international case studies.
• To synthesize shared and unique challenges and successes in integrated care implementation.
• To inform the development of practical guidelines and future research agendas for integrated care.

Main Methods:

• A multiple case study design was employed, guided by the Exploration, Preparation, Implementation, Sustainment (EPIS) framework.
• Seven international case studies from diverse healthcare systems, patient populations, and settings were analyzed.
• Qualitative synthesis was used to identify key drivers of implementation across the EPIS framework phases.

Main Results:

• Case studies spanned five countries and continents, representing varied clinical populations and care settings.
• Qualitative synthesis revealed common factors in the outer context, inner context, bridging, and innovation that facilitated implementation.
• The EPIS framework effectively guided the analysis of implementation efforts across different global contexts.

Conclusions:

• An agenda for advancing integrated care implementation research is proposed, focusing on priority goals and strategies.
• Key areas for future focus include the role of funding, meaningful stakeholder collaboration, and clear communication.
• These recommendations aim to support the systematic and effective integration of general and behavioral health services globally.
