Introduction Learning Health Systems (LHS) is a multifaceted subject. This paper reviewed current concepts as well as real-world experiences of learning health systems, drawing on published and unpublished knowledge in order to identify and describe important principles and practices that characterize learning health systems in low- and middle-income country (LMIC) settings.Methods We adopted an exploratory approach to the literature review, recognizing there are limited studies that focus specifically on system-wide learning in LMICs, but a vast set of connected bodies of literature. 116 studies were included, drawn from an electronic literature search of published and grey literature. In addition, 17 interviews were conducted with health policy and research experts to gain experiential knowledge.Results The findings were structured by eight domains on learning enablers. All of these interact with one another and influence actors from community to international levels. We found that learning comes from the connection between information, deliberation, and action. Moreover, these processes occur at different levels. It is therefore important to consider experiential knowledge from multiple levels and experiences. Creating spaces and providing resources for communities, staff and managers to deliberate on their challenges and find solutions has political implications, however, and is challenging, particularly when resources are constrained, funding and accountability are fragmented and the focus is short-term and narrow. Nevertheless, we can learn from countries that have managed to develop institutional mechanisms and human capacities which help health systems respond to changing environments with ‘best fit’ solutions.Conclusion Health systems are knowledge producers, but learning is not automatic. It needs to be valued and facilitated. Everyday governance of health systems can create spaces for reflective practice and learning within routine processes at different levels. This article highlights important enablers, but there remains much work to be done on developing this field of knowledge.
