Effects of the Health Transformation Plan on caesarean section rate in the Islamic Republic of Iran: an interrupted time series.

Background: In recent decades, the rate of caesarian section (C-section) has increased in the Islamic Republic of Iran. A reform in the Iranian health system - the Health Transformation Plan (HTP) - was launched in 2014 in which one of the objectives of HTP is decreasing the rate of C-section.

Aims: This study aimed to assess the effects of the Health Transformation Plan (HTP) on the C-section rate in the Islamic Republic of Iran.

Methods: This study was an interrupted time series analysis that used segmented regression analysis to assess the immediate and long-term effects of the HTP on C-section rate in two groups of hospitals affiliated and not affiliated to the Ministry of Health and Medical Education (MoHME) in Kurdistan province. Study samples were selected using the data on monthly C-section rate collected over a period of four years.

Results: We observed significant decreases in C-section rate immediately after the HTP in both groups of hospitals by 0.0629 and 0.0013, respectively (P < 0.05). In the long run, we observed no significant decrease in the regression slope of C-section rate in both groups.

Conclusions: The implementation of HTP decreased the C-section rate. However, the reduction does not meet expectations.
