The impact of health reform on poverty estimates in Iran: Implications for monitoring the first goal of Sustainable Development Goals.

INTRODUCTION Iran launched a series of health reforms called Health Transformation Plan (HTP) in order to improve financial protection and access to health care in 2014. This study aimed to investigate the extent of impoverishment due to out of pocket (OOP) payments during 2011-2016 and to assess the implications of health expenditures to overall national poverty rate before and after the HTP implementation, with a focus on monitoring the first Sustainable Development Goals (SDGs). METHODS The study relied on data from a nationally representative household income and expenditure survey. Two measures of poverty were estimated in this study: the prevalence (poverty headcount) and the intensity of poverty before and after OOP health payments (poverty gap). Proportion of the population fell into poverty due to OOP spending for health care from total poor population calculated for 2 years before and after the HTP implementation using three poverty lines suggested by the World Bank for global poverty comparison ($1.90, $3.2 and $5.5 per day in 2011 purchasing power parity (PPP) $). RESULTS Our results indicate that the incidence of impoverishing health expenditures has remained relatively low during 2011-2016. At the 2011 PPP $5.5 daily poverty line, the average incidence rate at the national level was 1.36% during the period. The percentage of population impoverished due to OOP health expenditures increased after HTP implementation, irrespective of the poverty line used. However, the proportion of individuals that pushed further into poverty decreased after HTP implementation. It was estimated that around 12.5% of total poor population fell below poverty line due to paying OOP payments in 2016. CONCLUSION Although health care costs are not major causes of impoverishment in Iran, the relative impact of OOP spending for health is not negligible. To attain SDG 1, pro-poor interventions that aim to reduce the burden of OOP payments should be advocated and implemented with an inter-sectoral approach.
