Population Characteristics
Table 2  presents the characteristics of the overall population and per year.  There was no significant difference between the years except for primiparity, a history of scarred uterus, and cesarean section during labor. These data are different for the year 2017 compared to other years (p < 0.05).
Overall, 250 of the 800 cesarean sections were coded green (31.3%), 263 orange (32.9%), and 85 red (10.6%). For 202 patients (25.3%), the color code was missing from the medical record, whether computerized or paper. These data are presented in Table 3 . Between 2015 and 2018, the number of patients for whom a color code was not mentioned in the file decreased significantly (p<0.0001). These were mainly for green and orange coded cesarean sections, for which the number increased significantly over the years (p < 0.0001). Conversely, there was no significant difference in the number of red code cesarean sections.
