Objective To enhance the qualified rate of preoperative bladder filling and improve the experience of embryo transfer by implementing a nursing intervention based on the root cause analysis and plan-do-check-act(RCA-PDCA)cycle.Methods A before-after comparative study was conducted among the patients who received embryo transfer at a Tire-ⅢA specialist hospital between January and April 2024.The patient who received embryo transfer between January and February 2024(n=130)were assigned to the control group with routine nursing.Those who received embryo transfer between March and April 2024 were assigned to the trial group(n=136)with nursing intervention based on RCA-PDCA.The two groups were compared in terms of the qualified rate of bladder filling,endometrial visualisation rate,instrument-assisted transfer rate and level of comfort.Results A total of 126 women in the control group and 131 in the trial group completed the study.The patient in the trial group demonstrated significantly higher qualified rate of bladder filling and endometrial visualisation rate in comparison with those in the control group(70.2％vs.38.1％,81.7％vs.51.6％,respectively).The trial group also had lower rates in both of the instrument-assisted transfer and the incidence of mild pain than those in the control group(2.3％vs.7.9％,32.1％vs.53.2％,respectively;P<0.05).Conclusion RCA-PDCA is effective in improving preoperative bladder filling and endometrial visualisation,reducing instrument-assisted transfer and enhancing preoperative bladder comfort in the women receiving embryo transfer.

Objective:To investigate the effect of water intake on bladder filling time before embryo transfer.Methods:A total of 189 patients were collected from February to June 2023 who were to undergo embryo transfer in Guangdong Women and Children Hospital. The patients were divided into group A ( n=61), group B ( n=64) and group C ( n=64) using a random number table and they were respectively given 300 mL, 500 mL and 700 mL water to drink. Abdominal ultrasound was performed every 15 min, a total of 1-5 times, from 45 min after drinking water until the bladder filling. The bladder filling time and bladder volume were collected. Kaplan-Meier method was used to compare the difference of bladder filling time among the three groups. The multivariate Cox regression was used to analyze factors of bladder filling time. Results:The cumulative bladder filling rates of group A, group B and group C at 105 min after drinking water were 57.4% (35/61), 90.6% (58/64) and 98.4% (63/64), respectively, and the median survival time (95% CI) of bladder filling was 105.0 (89.9-120.1) min, 60.0 (55.4-64.7) min and 60.0 (55.4-64.6) min, respectively. Pairwise comparison of Kaplan-Meier analysis revealed that the bladder filling time of group A was longer than that of group B and group C ( P<0.001), and there was no statistically significant difference between group B and group C ( P>0.05). The results of age-stratification analysis showed that the bladder filling time of younger patients in group A [90.0 (75.2-104.8) min] was longer than that in group B [60.0 (55.8-64.2) min, P<0.001] and group C [60.0 (55.1-64.8) min, P<0.001], and there was no statistical significance between group B and group C ( P>0.05); the bladder filling time of older patients in group C [60.0 (59.1-70.9) min] was shorter than that in group A [105.0 (89.9-120.1) min, P<0.001] and group B [75.0 (64.3-85.7) min, P=0.027], there was no statistical significance between group A and group B ( P>0.05). Multivariate Cox regression analysis showed that taking group A as reference, the hazard ratio ( HR, 95% CI) of groups B and C were 2.71 (1.78-4.21) and 3.23 (2.10-4.96), both P<0.001. The HR (95% CI) of the elderly patients was 0.69 (0.49-0.99), P=0.044. Conclusion:Water intake and age are independent factors affecting bladder filling time in embryo transfer patients. Patients are recommended to drink 500 mL of water 75 min before embryo transfer and appropriately increase the amount of water or extend the bladder preparation time after drinking water for elderly patients.

Objective:To investigate the current situation of general practitioners' occupational pressure in Heilongjiang Province, and explore its relationship with professional identity and perceived organizational support. It aims to provide references for the construction of general practitioners and the development of general medical education.Methods:The general situation questionnaire, perceived organizational support scale, occupational pressure scale, and professional identity scale were applied through network and site surveys for collecting data. A total of 288 questionnaires were collected with 263 valid questionnaires (91.3%). Pearson correction analysis and bootstrap analysis were performed for data analysis.Results:The average score of occupational pressure among general practitioners was (115.95±22.40), and the results of Pearson correction analysis showed that perceived organizational support was negatively correlated with occupational pressure ( r=-0.413, P<0.01) and positive correlation with professional identity ( r=0.587, P<0.01). There were also significant negative correlations between professional identity and occupational pressure ( r=-0.442, P<0.01). Moreover, the mediating effect showed that professional identity had a certain mediating effect on the relationship between perceived organizational support and occupational pressure (LLCI=-0.2039, ULCI=-0.0760, P<0.05). Conclusion:General practitioners' occupational pressure was at a high level, which can be reduced through improving the perceived organizational support and professional identity.
