Objective This study develops and evaluates a just-in-time adaptive intervention(JITAI)-based smart nursing protocol for interventional radiology preoperative waiting areas,assessing its impact on patient experience Methods A time-series design was employed.Patients in the waiting area of an interventional operating room at a tertiary hospital in Chengdu,Sichuan Province,were studied during April and August 2024.Participants were divided into an intervention group(n=766)and a control group(n=864).The intervention group received the newly developed management protocol,while the control group received conventional nursing care.Differences between the groups were compared regarding perceived waiting time,actual waiting time,preoperative anxiety levels,and satisfaction rates.Results Totally 13 participants were lost to follow-up in the intervention group and 11 in the control group,resulting in final analyzed cohorts of 753 and 853 patients,respectively.The median actual waiting time was significantly shorter in the intervention group with 50.03(23.92,76.38)min,compared to the control group with 65.62(35.77,104.32)min.A significant difference was observed between the 2 groups(P＜0.001).Similarly,the median perceived waiting time was significantly lower in the intervention group with 48.00(20.00,70.00)min than 73.00(38.00,105.00)min in the control group.A significant difference was observed between the 2 groups(P＜0.001).The anxiety score during the waiting period was lower in the experimental group than it in the control group,and the experimental group showed a significantly higher satisfaction level compared to the control group,with both dif ferences being statistically significant(P＜0.05).Conclusion The intelligent nursing program,developed based on the JIT AI theory,effectively reduces both the actual and perceived preoperative waiting time for patients in the in-terventional operating room,optimizing their preoperative waiting experience.

Objective To understand the implementation of WS/T 508-2016 and the status of washing and disin-fection of medical textiles in China,and provide basis for the revision of the standard.Methods A questionnaire survey was conducted on the management of medical institutions and washing and disinfection workplace,building layout,personnel protection,equipment and supplies,washing and disinfection principles,and hygiene quality mo-nitoring of medical textiles in 323 medical institutions and 31 washing institutions in China.Meanwhile,microbio-logical index sampling was conducted on 234 pieces of medical textiles in 9 medical institutions and 8 washing insti-tutions in Hubei,Shanxi,Shanghai,and Sichuan Provinces before and after washing and disinfection.Results The awareness rates of WS/T 508-2016 among medical institutions and washing institutions were 96.90％and 96.77％,respectively,and the implementation rates were 94.12％and 96.77％,respectively.47.99％medical in-stitutions use purchasing services for washing and disinfecting medical textiles,and the higher the level of the medi-cal institution was,the higher the proportion of purchasing services was(x2=15.312,P＜0.001).85.16％medi-cal institutions have conducted risk assessments on service providers,and 52.99％were responsible for or participa-ted in pre-job training by the medical institution.Washing institutions were higher than medical institutions in terms of system soundness rate,pre-job training rate,proportion of quality management leaders and full-time(part-time)quality inspectors,setting rate of hand-washing facilities in zones,passages,isolation barriers,dressing(buffer)room,and toilets,configuration rate of hygiene isolation washing equipment,tunnel washing unit,washing equip-ment with heating functions,drying equipment and mechanical ventilation facilities,and specialty machine washing rate.Among 234 medical textiles specimens,11.97％were detected fungi,and the total fungal colonies in 5 clean textiles exceeded 100 CFU/100 cm2.Conclusion WS/T 508-2016 can further standardize the washing and disin-fection of medical textiles in China through strengthening institutional management,improving the supervision level of service providers,perfecting hardware facilities and layout,introducing new technologies,and increasing the mo-nitoring on fungi in clean textiles.

Objective Based on the analysis of the results of retesting of blood donors with human immunodeficiency virus(HIV)serological single-reagent reactivity,the rationality and practical effect of the existing retesting strategy were discussed.Methods HIV serological single-reagent reactivity blood donors in Wenzhou from January to December 2023 were selected as the study objects,and were confirmed by Wenzhou Center for Disease Control and Prevention(CDC)and returning test to confirm whether they could be returnee.Differences in return rates were analyzed by the basic data of blood donors and the S/CO value of HIV serological test during screening.Results Among the 374 HIV serological single-reagent reactivity blood donors,55 were confirmed by CDC with uncertain HIV antibodies,319 met the criteria for return,and 84 actively applied for return.78 showed no reactivity through self-test and return test and were allowed to return to the team.Four showed HIV serological reactivity,one showed HIV nucleic acid testing(NAT)test reactivity,permanent shielding.One showed the reactivity of anti-HIV chemiluminescence immunoassay test,and the HIV NAT test was noreactivity,and continued to be screened to participate in the next round of return.There were statistically significant differences in the permissible return rate of blood donors with different ages,blood types and blood donation times(P<0.05).There was no significant difference in the allowed return rate of blood donors with different S/CO values during screening(χ2=1.898,P=0.168).Conclusion Reasonable return procedures can effectively reduce the loss of blood donors and ensure the safety of blood for clinical use.

Objective: To investigate the causes and characteristics of immune hemolytic transfusion reactions (HTRs) triggered by anti-E antibodies, so as to provide a scientific reference for guaranteeing clinical blood transfusion safety. Methods: Five patients who experienced HTRs in our hospital from November 2023 to October 2024 were selected as the research subjects. ABO/RhD blood grouping, antibody screening, antibody identification, and the direct antiglobulin test (DAT) were conducted using the column agglutination method. The causes of HTRs in these patients were investigated using multiple techniques such as the two-step enzyme method, polyethylene glycol (PEG), acid elution technique, and capillary centrifugation method. Results: All five patients tested negative for antibody screening prior to transfusion. However, after transfusion of E+ phenotyped blood, patients 1, 2, 3, and 5 developed delayed haemolytic transfusion reaction (DHTR), while patient 4 experienced acute haemolytic transfusion reaction (AHTR). Anti-E antibodies were detected in all blood samples from the patients after the hemolytic transfusion reaction, including the enzyme-only anti-E antibody in two cases. Conclusion: Anti-E antibody can trigger both intravascular and extravascular hemolysis. It is recommended to conduct ABO/RhD and RhE antigen-matched transfusions and establish a regional blood transfusion database to reduce immune hemolytic transfusion reactions caused by anti-E antibody.

Objective:To investigate the rates of low disease activity and clinical remission in patients with systemic lupus erythematosus(SLE)in a real-world setting,and to analyze the related factors of low disease activity and clinical remission.Methods:One thousand patients with SLE were enrolled from 11 teaching hospitals.Demographic,clinical and laboratory data,as well as treatment regimes were collec-ted by self-completed questionnaire.The rates of low disease activity and remission were calculated based on the lupus low disease activity state(LLDAS)and definitions of remission in SLE(DORIS).Charac-teristics of patients with LLDAS and DORIS were analyzed.Multivariate Logistic regression analysis was used to evaluate the related factors of LLDAS and DORIS remission.Results:20.7％of patients met the criteria of LLDAS,while 10.4％of patients achieved remission defined by DORIS.Patients who met LLDAS or DORIS remission had significantly higher proportion of patients with high income and longer disease duration,compared with non-remission group.Moreover,the rates of anemia,creatinine eleva-tion,increased erythrocyte sedimentation rate(ESR)and hypoalbuminemia was significantly lower in the LLDAS or DORIS group than in the non-remission group.Patients who received hydroxychloroquine for more than 12 months or immunosuppressant therapy for no less than 6 months earned higher rates of LLDAS and DORIS remission.The results of Logistic regression analysis showed that increased ESR,positive anti-dsDNA antibodies,low level of complement(C3 and C4),proteinuria,low household in-come were negatively related with LLDAS and DORIS remission.However,hydroxychloroquine usage for longer than 12 months were positively related with LLDAS and DORIS remission.Conclusion:LLDAS and DORIS remission of SLE patients remain to be improved.Treatment-to-target strategy and standar-dized application of hydroxychloroquine and immunosuppressants in SLE are recommended.

Objective To investigate the correlation and consistency between the parameters of thromboelastography(TEG)and routine coagulation tests,and to evaluate the application value of the two methods in heparin anticoagulation monitoring and coagulation function monitoring in patients receiving extracorporeal membrane oxygenation(ECMO)therapy.Methods A total of 138 patients who recieved ECMO in the Department of Critical Care Medicine of the People's Hospital of Guangxi Zhuang Autonomous Region from October 2021 to December 2022 were selected.A total of 317 pairs of ordinary TEG and heparinase-modified TEG(hmTEG)parameters measured simultaneously were analyzed for correlation and consis-tency with activated partial thromboplastin time(APTT),fibrinogen(Fib),and platelet count(Plt),and the parameters tested when ECMO was established and 24 hours after ECMO operation were compared.Results The correlation coefficient between R values and APTT of hmTEG(r=0.441,P<0.05)was lower than that of ordinary TEG(r=0.547,P<0.05).The parameters α-Angle and K value of ordinary TEG were not correlated with Fib(P>0.05),while as for hmTEG,the correla-tion was 0.359(P<0.05)and-0.343(P<0.05),respectively.The correlation between MA value of hmTEG and Plt was 0.456(P<0.05),which was much lower than its correlation with Fib(r=0.715,P<0.05).APTT and hmTEG had moderate agreement in judging the anticoagulant effect of UFH(P<0.05).Plt at 24 hours after ECMO was significantly lower than that at establishment of ECMO(P<0.05).Fib,APTT and hmTEG parameters were not significantly different between the two groups(P>0.05).Conclusion The parameters of hmTEG can better reflect the real level of coagulation factors in patients receiving ECMO.The results of hmTEG and APTT are complementary to assess whether heparin in ECMO patients is over-dosed,and hmTEG has unique advantages.Routine coagulation tests and TEG cannot replace each other,and the combina-tion of them can achieve better anticoagulation and coagulation management.

Objective To analyze the risk factors of malnutrition in multidrug resistant tuberculosis(MDR-TB)patients.Methods A total of 96 MDR-TB patients admitted to Jiangxi Chest Hospital from September 2021 to March 2023 were selected as study objects.The malnutrition status of patients was evaluated by using mini-nutritional assessment short-form,and the basic data of patients were investigated.Logistic regression analysis was used to investigate the risk factors of malnutrition in MDR-TB patients.Results Of 96 MDR-TB patients,51 cases(53.12%)were malnourished.Logistic regression analysis results showed that age≥60 years old,chronic diseases,insomnia,anxiety and depression,and family dysfunction were all risk factors for malnutrition in MDR-TB patients(P<0.05).Conclusion MDR-TB patients have a high risk of malnutrition,which is affected by age,chronic diseases,sleep status,psychological status,and family function.Nursing programs can be formulated according to the above factors,such as sleep guidance,psychological support,and family intervention,in order to reduce the risk of malnutrition in patients.
