It has always been argued that countries should not be inactive about the quality of health services. Therefore, a clear policy needs to be created regarding how quality of health services should be. The present scoping review was aimed to identify and map the available evidence regarding the National Quality Policy and Strategy (NQPS) of the health services in health systems of developing countries, graphically and tabularly. We followed the published methodological guidance of the Joanna Briggs Institute reviews. Also, we employed a narrative thematic synthesis integrated with the systematic analysis using the World Health Organization's approach of NQPS, and the multiple-streams framework of Kingdon. We included 33 records that met the inclusion criteria; these records were published between 2010 and 2019. Meanwhile, government documents were the most frequent records (61%). Zimbabwe, Indonesia, and Sudan were the most frequent locations (each one 8%). The Ministry of Health was in charge of the ultimate responsibility for developing the NQPS in all identified countries. Besides, 82% of the countries were in the development phase of NQPS formulation, and convergence of three streams was observed in Indonesia, Sudan, and Tanzania. It seems that the African countries were informed about their quality issues, and the need for having NQPS have been more popular with them. We recommend that future research focuses on examining NQPS in terms of prioritizing in the agenda-setting phase of the policy-making cycle, and also, document analysis of all identified NQPS based on the core eight interdependent elements related to the NQPS approach.
