Objective To explore the effect of continuous quality improvement on reducing the incidence of urinary retention after natural childbirth.Methods This study was a clinical observation study.We selected the parturients who gave birth naturally in Guangdong Women's and Children's Hospital from January to December 2021 as the research objects.Among them,3 062 parturients in the first delivery area were taken as the experimental group,3 112 parturients in the second delivery area were taken as the control group.The maternal age of the experimental group was(29.52±4.25)years old;perineal wound:there were 266 cases of no wound,2 152 cases of grade Ⅰ laceration,and 644 cases of grade Ⅱ laceration and lateral incision.The maternal age of the control group was(29.68±4.09)years old;perineal wound:there were 244 cases of no wound,2 179 cases of grade Ⅰ laceration,and 689 cases of grade Ⅱ laceration and lateral incision.The control group was given routine urine retention nursing measures,and the observation group was given continuous quality improvement management measures on the basis of routine nursing.The incidence of urinary retention,the rate of indwelling catheter,and the standardized use rate of nursing sheet in parturients with urinary retention were observed in the experimental group and the control group,and the incidence of urinary retention,the rate of indwelling catheter,and the standardized use rate of nursing sheet in parturients with urinary retention were compared before and after improvement.x2 test,rank sum test,and independent sample t test were used.Results There were statistically significant differences in the incidence of urinary retention,the rate of indwelling catheter,and the standardized use rate of nursing sheet in parturients with urinary retention between the experimental group and the control group[3.20%(98/3 062)vs.4.45%(139/3 112),1.40%(43/3 062)vs.2.80%(87/3 112),88.78%(87/98)vs.56.12%(78/139)](x2=6.702,14.354,and 29.988,all P<0.05).The comparison before and after improvement showed that there were statistically significant differences in the incidence of urinary retention,the rate of indwelling catheter,and the standardized use rate of nursing sheet in parturients with urinary retention(all P<0.05).Conclusion Continuous quality improvement can effectively reduce the incidence of urinary retention after natural childbirth and improve the level of nursing quality.
