Implementation Research and Delivery Science

In public health research, the focus has traditionally been on descriptive and analytic epidemiological research (“what”, “why”, “where,” and “who”). Less attention has been given, particularly in low-income countries, to “how” interventions do or do not work in the “real world”, given the involvement of different actors, the context in which implementation occurs, and the factors that influence implementation. Future Health Systems (FHS) has been at the forefront in the exploration, application and growth of implementation research (IR).
