The influential factors for achieving universal health coverage in Iran: a multimethod study

BACKGROUND: The initial purpose of healthcare systems around the world is to promote and maintain the health of the population. Universal Health Coverage (UHC) is a new approach by which a healthcare system can reach its goals. World Health Organization (WHO) emphasized maximum population coverage, health service coverage, and financial protection, as three dimensions of UHC. In progress for achieving UHC, recognizing the influential factors allows us to accelerate such progress. Therefore, this study aimed to identify the influential factors to achieve UHC in Iran. METHODS: This is a multi-method study was conducted in four phases: First, a systematic review of the literature was conducted to identify the factors in PubMed, Web of Science, Embase, Scopus, ProQuest, Cochrane library, and Science Direct databases, and hand searching google scholar search engine. For recognizing the unmentioned factors, a qualitative study consisting of one session of Focus Group Discussion (FGD) and five semi-structured interviews with experts was designed. The extracted factors were merged and categorized by round table discussion. Finally, the pre-categorized factors were refined and re-categorized under the health system’s control knobs framework during three expert panel sessions. RESULTS: Finally, 33 studies were included. Eight hundred two factors were extracted through systematic review and 96 factors through FGD and interviews (totally, 898). After refining them by the experts’ panel, 105 factors were categorized within the control knob framework (financing 19, payment system7, Organization 23, regulation and supervision 33, Behavior 11, and Others 12). The majority of the identified factors were related to the “regulation and supervision” dimension, whilst the “payment system” entailed the fewest. The political commitment during political turmoil, excessive attention to the treatment, referral system, paying out of pocket(OOP) and protection against high costs, economic growth, sanctions, conflict of interests, weakness of the information system, prioritization of services, health system fragmented, lack of managerial support and lack of standard benefits packages were identified as the leading factors on the way to UHC. CONCLUSION: Considering the distinctive role of the context in policymaking, the identification of the factors affecting UHC accompanying by the countries’ experiences about UHC, can boost our speed toward it. Moreover, adopting a long-term plan toward UHC based on these factors and the robust implementation of it pave the way for Iran to achieve better outcomes comparing to their efforts.
