The aim of this study was to investigate the changes in the level and trends of average inpatient cost in Behshahr Imam Khomeini Hospital during implementation of the Family Physician Plan (FPP) and Health Transformation Plan (HTP). Materials and methods: In this longitudinal study based on Interrupted Time Series (ITS), the data included monthly average inpatient cost in Behshahr Imam Khomeini Hospital during seven years (2011-2018). Data analysis was conducted in segmented regression model in R 3.6.1. Results: The growth rate of the number of inpatient cases was negative for two consecutive years after implementation of the FPP. The highest growth rate of average inpatient cost was 83% that occurred in 2014 (the first year after implementation of HTP). The change in the level of average inpatient cost at the beginning of the HTP was significant (P<0.001) compared to before that which increased by 3,896,826 Rials. Conclusion: Over the past decade, change in the average cost of hospitalization has experienced a heterogeneous trend influenced by the FPP and the HTP. Further studies are recommended to investigate the impacts of different components and packages of these reforms on health spending. LA eng UL http://jmums.mazums.ac.ir/article-1-15874-en.html M3 ER -
