Introduction: Integrated care of chronic patients improves quality of their management, but there is scarce evidence of its implementation in different healthcare settings. With this article, we wanted to determine the level of integrated care implementation in the management of T2D (diabetes) and HT (hypertension) in three different settings: Belgium, Slovenia, and Cambodia. Methods: This was an observational study with integrated approach. It was conducted in primary health care organisations in three countries. In each primary health care organisation, we aimed to include primary care workers that worked with Type 2 Diabetes (T2D) and hypertension (HT) patients. Data was collected with the Integrated Care Package (ICP) grid (consisting of six elements: identification, treatment, health education, self-management, caregiver collaboration, and care organisation). Results: ICP is almost completely implemented without major differences within Slovenia. There is a considerable variability across practice types in Belgium. Implementation is constrained by health system resources in Cambodia. Some elements, especially identification, are better implemented then others, across health systems. Conclusion: Countries can enhance integrated care for chronic diseases by implementing central policies, standardized protocols, and local adaptation, addressing resource constraints, promoting systematic screening and health education, and providing training for healthcare workers, tailored to community needs, to improve patient outcomes and healthcare delivery.
