Objective To construct a risk prediction model of the postoperative delirium for patients with acute type A aortic dissection（ATAAD）,and to verify the prediction effect of the model. Methods A retrospective study was conducted among 245 adult patients undergoing aortic dissection surgery in the cardiac surgery department of a tertiary A hospital in Wenzhou from October 2020 to April 2021. According to the occurrence of postoperative delirium,the patients were divided into a delirium group （n=51） and a non-delirium group （n=194）,and the data of the 2 groups were compared. The risk prediction scoring model was constructed based on the multivariate logistic regression analysis of ATAAD postoperative delirium risk factors. The Hosmer-Lemeshow test was used to determine the model’s goodness of fit of the model,and the receiver operator characteristic curve （ROC） was used to test the model differentiation. The risk prediction model was validated by the prospective study with inclusion of 51 ATAAD patients admitted to the cardiac surgery department from July,2020 to June,2021. Results There were 6 factors included in the risk prediction model of patients with postoperative delirium,namely age over than 55.50 years（1 point）,male（1 point）,preoperative blood lactic acid value more than 1.85 mmol/L（1 point）,hypothermia cycle arrest time more than 36.50 minutes（1 point）,length of stay in CCU（cardiovascular intensive care unit）more than 8.50 days（2 points）,and other postoperative complications（1 point）. The Hosmer-Lemeshow test of the prediction scoring model showed that when P=0.393,the area under the ROC was 0.926. When the patient’s score was ≤4,the incidence of postoperative delirium in patients with ATAAD was≤15.63%;while it was≥5,the incidence was ≥50.00%. The sensitivity,specificity and accuracy of the risk stratification model were 76.47%,93.30% and 89.80%,respectively. The result of model verification shows that when the area under the ROC was 0.896,the Hosmer-Lemeshow test P=0.359. The sensitivity,specificity and accuracy of the risk stratification model were 75.00%,92.31% and 88.24%,respectively. Conclusion This risk prediction model provides an effective prediction effect,and it is simple and convenient to use in clinical application,which could be a reference for medical staff to take preventive treatment and nursing care.

Objective To investigate the clinical safety of pulling peripheral venous indwelling needle according to clinical indications,and compare its effect with conventional indwelling needle extraction. Methods A multicenter randomized controlled trial was conducted with a total of 3,669 patients in 12 tertiary general hospitals from March 2019 to July 2019. The patients were randomly allocated into the observation group（group A） and the control group （group B） by the random number table. The puncture methods were consistent between the two groups. Researchers compared the indwelling time,the incidence of catheter-related complications within 96 hours,and the risk ratio of catheter-related complications during the entire indwelling period（phlebitis,occlusion,and infiltration,suspected infection） between two groups,among which phlebitis was the primary outcome indicator and other complications as secondary outcome measures. Results A total of 3,642 patients were enrolled in the study with 1,803 cases in group A and 1,839 cases in group B. The indwelling time of group A was（85±52）h and it was longer than that of （71±30） h in group B with a statistical difference（P<0.001）. Within 96 h of indwelling time,there was no statistical differences in the risk of phlebitis,infiltration and suspected infection between two groups（P>0.05）. During the entire indwelling period,the risk of occlusion in group A was higher than that in group B with a statistical difference（P<0.05）. The other indicators showed no statistical difference. Conclusion The placement of indwelling needle based on clinical indications can prolong the indwelling time without increasing the risk of phlebitis,infiltration and suspected infection,but the risk of occlusion will increase. If the catheter is removed according to clinical indications,monitoring and evaluation of occlusion should be strengthened.

Objective To understand the occurrence and protection status of three occupational exposures：needle-stick injury by nurses,blood exposure and workplace violence in the emergency department in tertiary hospitals in Beijing. Methods According to the schedule of the emergency department of each hospital,one group of nurses were selected from each hospital in 21 tertiary hospitals in Beijing to participate in the online survey. Self-designed online questionnaires were distributed and completed anonymously,including general information,the occurrence status and protective behaviors of needle-stick injury by nurses,blood exposure and workplace violence. Results A total of 1,150 questionnaires were collected,of which 1,102 were valid,with an effective rate of 95.83%. In the past year,the incidence rates of at least one needle-stick injury by emergency department nurses,blood exposure during blood collection,verbal violence,physical violence and sexual harassment were 37.8%,36.4%,68%,12%,and 5.3%,respectively. In different working areas at emergency department,the occurrence of needle-stick injury（χ ²=16.805,P=0.01）,verbal violence（χ ²=98.509,P<0.001） and physical violence（χ ²=79.916,P<0.001） were different. Among nurses with occupational exposure,92.8% were able to squeeze blood after needle-stick injury,flush with flowing water and disinfect;69.8% were able to flush and disinfect exposed parts after blood exposure in the process of blood drawing. Among nurses encountering workplace violence,41.3% explained patiently,and 30.0% adopted tolerance and avoidance. In addition,the reporting rate of all three types of occupational exposure was low（less than 30%）. Conclusion The incidence of occupational exposure in emergency department is relatively high. Nursing managers should attach importance to the construction of the work environment in emergency department,strengthen the training of pre-exposure protection in blood collection process and workplace violence,and strengthen the reporting and management of the three types of occupational exposure.
