The purpose of HS4TB Contracting policy primer is to highlight the actions that are needed to create the enabling environment for contracting health services and are relevant to countries considering contracting or looking to improve their existing contracting practices. How these actions are sequenced and conducted is both opportunistic and unique to context. There are no generalized “how-to” steps or processes that countries ought to follow. This primer provides some ideas, useful resources and questions to consider along this journey. Whereas, The purpose of HS4TB Contracting Paper is to identify and synthesize commonalities in the practice of establishing contracting out (referred to as contracting in this paper) for health services – thus highlighting issues that may be relevant to policymakers considering engaging non-government partners through this mechanism.1 The aim is to learn from countries that have sustainable contracting practices as defined by either government funding and/or use of national health systems (e.g., procurement, payment and management systems) for contracting.
