Interrupted time series with comparison between pre- and post-intervention period. The time series of quarterly changes in the percent of cases using general anesthesia (GA) from January 2010 to December 2019 were generated to provide a compassion before and after the intervention. The data show a level change in the proportion of GA cases following the launch of our obstetric anesthesia team in 2015. The blue dots in the post-intervention period 2015–2019 are all positioned below the line (red dashed line) representing the pre-existing trend seen during the pre-intervention period 2010–2014. Interrupted time series analysis revealed that the percent of GA cases was significantly decreased in the post-intervention period (P = 0.04). No significant change in slope was found between pre- and post-intervention (P = 0.74)
