OBJECTIVES Western countries healthcare systems face growing challenges dealing with disability and death due to chronic diseases. Coordination of healthcare services has become unavoidable. Our objective was to identify the Integrated Health Services (IHS) in the major healthcare markets and understand the funding process. METHODS IHS provided in Europe, North America and Asia were identified through a literature review. Future perspectives were based on country policy and observed trends.  RESULTS All studied countries developed IHS such as disease management, case management and telemonitoring services, with the United States (US) being the major market. However, levels of implementation, funding processes and stakeholders involved vary highly between different countries. Funding processes such as fee for services and capitation are widely used in all studied countries and Payment for performance (P4P), bundled payment and diagnosis-related group (DRG) for outpatient are in progress, used mainly in the US, and to a much lower extent in the United Kingdom (UK) and Germany. Multiple IHS exists in France, though inappropriate incentives hinder their development. In the US, under the Affordable Care Act, Accountable Care Organisations (ACOs) are testing a range of payment models (capitation, one-sided/two-sided shared saving fee-for-service, bundled/episode payments and P4P).  CONCLUSIONS IHS have become ubiquitous in all health organisations. All countries studied are expected to develop more IHS based on P4P schemes. The P4P of ACOs represents the ultimate gold mine for the development of paid health care services. Even if this concept is still in progress it will be leading this market. This will also change dramatically the way pharmaceutical companies will do business. Drugs will have to be integrated in a more complex selling process driven by medium to long term outcome impact. The management of confounding factors on outcomes is critical and represents the challenge for ACOs.
