METHOD: All published articles related to the FPP in Iran were included in this study. In particular, original qualitative studies published in English or Persian from 2011 to 2021 were included. In January 2022, international credible scholarly databases and Persian databases were searched. All selected articles were carefully studied, and the data were extracted using the sample, phenomenon of interest, design, evaluation and research type technique. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses were used in preparing the study report.

RESULTS: Among 491 articles retrieved from the search strategy, 50 met the inclusion criteria after their titles and abstracts were screened. Twenty-nine studies were excluded after their full texts were reviewed. A total of 11 eligible empirical studies were finally included. Based on the results, six broad categories (budget and funding, insurance system, tariffs, payments, accountability and injustice) were identified as financial challenges.
