Abstract:Objective To explore the application effect of anticipatory care quality control circle (QCC) based on root cause analysis on reducing intrapartum hemorrhage in vaginal delivery women. Methods A QCC was established and the theme was set as “reducing postpartum hemorrhage”. At the Nanjing Drum Tower Hospital, 43 parturients who delivered vaginally from March 14 to 24, 2022 were selected as the control group, and 43 parturients who delivered vaginally from September 5 to 15, 2022 were selected as the observation group. The control group received routine nursing methods, while the observation group received predictive nursing based on root cause analysis. The incidence of postpartum hemorrhage, bleeding volume, perineal lateral resection rate, and the comprehensive ability score of midwives between two groups were compared. Results Nine people in the control group experienced bleeding during childbirth (20.93%), while 6 people in the observation group experienced bleeding during childbirth (13.95%). The difference in the incidence of postpartum hemorrhage between two groups was statistically significant (χ²2=0.727, P=0.394). The bleeding volume in the observation group was significantly reduced compared to the control group ［(532.3 ± 138.9) mL vs (678.6 ± 214.5) mL,t=3.754, P＜0.05］. The perineal lateral resection rate in the observation group was lower than that in the control group (16.28% vs 25.58%, χ²=1.124, P=0.289). Conclusion Anticipatory care based on root because analysis can significantly reduce the amount of postpartum hemorrhage in vaginal delivery women, reduce the risk of postpartum bleeding caused by uterine atony and perineal lateral incision, and improve the comprehensive ability of midwives.
