Objective:To design a management system of internet of things(IoT)smart operation room based on business process reconstruction theory,and explore the application effect of that in improving management effectiveness for operation room.Methods:Aimed at the existing problems of key points in the management for operation room,the process was reconstructed on the basis of the original information system,relevant systems,workflows and standards of operation room of Fuwai Hospital of Medical Sciences and Peking Union Medical College.Then,a management system of IoT smart operation room based on business process reconstruction theory was designed.The surgical data of 13159 patients who underwent relevant operation of cardiovascular surgery from January to December 2022 were selected,and they were divided into"before-application"group(6 483 cases)and"after-application"group(6 676 cases)according to the point before and after the system was applied.Some indicators'data,which included scheduling management situation of picking up and dropping off patients by medical auxiliaries,duration of preparing anesthesia,duration of preoperative waiting,interval duration of continuous surgery and usage amount of surgical gowns under same amount of surgery,between two groups were compared.Results:The transportation efficiency of patients who underwent surgery after system was applied was(1.38±0.09)surgeries/h,which was higher than(0.99±0.09)surgeries/h before it was applied,and the difference was statistically significant(t=6.604,P<0.001).The satisfaction score of medical auxiliaries increased from 3.83(3.33,4.5)before application to 4.50(4.33,4.83)after application,and the difference was significant(Z=2.02,P<0.05).The duration of preparing anesthesia and duration of preoperative waiting after the system was applied were respectively(62.04±2.29)and(8.09±2.46)min,both of which were less than those before the system was applied,and the differences of them between two groups were statistically significant(t=2.309,2.280,P<0.05).The usage amount of surgical gowns under same amount of surgery after the system was applied was(4.11±0.57)gowns/surgery,which was less than(5.81±0.29)gowns/surgery before the system was applied,and the difference was statistically significant(t=6.489,P<0.05).Conclusion:The application of the management system of IoT smart operation room based on business process reconstruction theory can provide more safely,high-qualitatively and efficiently medical services for patients,and improve work efficiency and management effectiveness for operation room,and reduce resource consumption and operating cost.

Objective To evaluate the frailty status and risk factors among hospitalized elderly patients after percutaneous coronary intervention(PCI),and to provide a reference for improving and delaying their frailty.Methods From March to August 2024,using convenience sampling,patients aged over 75 years who underwent PCI in a tertiary cardiovascular disease specialist hospital in Beijing were selected as the survey participants.Patient-related informations were collected through a self-designed general information questionnaire.The Fried Phenotype Frailty Scale,the Katz Activities of Daily Living,Lawton Instrumental Activities of Daily Living(IADL)scale,the Charlson Comorbidity Index,the Morse Fall Scale,the Mini Nutritional Assessment-Short Form(MNA-SF),and the 15-item Geriatric Depression Scale(GDS-15)were evaluated postoperatively until discharge.Univariate and multivariate logistic analyses were conducted to identify factors associated with frailty among patients after PCI.Results A total of 278 patients were included.The incidence of frailty after PCI was 52.16％.Based on Fried Phenotype scores,patients were divided into a non-frail group and a frail group.Univariate analysis showed statistically significant differences between the 2 groups in terms of age,gender,hemoglobin,NT-ProBNP,LVEF,IADL scores,living alone status,nutrition status,falls risk,and depression level(P＜0.05).Multivariate logistic regression analysis revealed that age,Lawton IADL scores,falls risk,nutrition status,depression level were factors influencing frailty,with odds ratios of 1.167,0.575,1.597,0.399,and 3.610,respectively(P＜0.05).Conclusion The incidence of frailty is high among patients aged over 75 years after PCI,and there are multiple risk factors affecting their frailty status.Clinical healthcare providers should prioritize long-term management of these patients and implement comprehensive interventions with the consideration of their physiological,psychological,and social conditions.

This study summarizes the preoperative and intraoperative nursing experience in 5 cases of bridge-to-transplant heart transplantation with left ventricular assist device(LVAD)explant.Key points of nursing include:preoperative care and assessment of LVAD patients,preoperative discussion of the multidisciplinary team,safe transfer of patients to surgical rooms and other preoperative preparation,cardiomyocardial protection and multidisciplinary team cooperation during bridging transplantation,and intra-operative patient safety management.All 5 patients in this group successfully completed the surgery and were discharged.Pressure sores,wound infections,and other postoperative complications have not occurred.Postoperative cardiac function of 5 patients in this group were classified as New York Heart Association class Ⅰ～Ⅱ.The follow-up period for the 5 patients in this group ranged from 6 months to 6 years.The results of the most recent echocardiography follow-up showed that the left ventricular ejection fraction of all patients was all above 65％,with well prognosis.

Objective To explore the expert consensus on perinatal care management of infants with congenital heart disease(hereinafter referred to as"Consensus")in order to promote the standardization of integrated nursing.Methods The literature was systematically searched and several discussions were organized within the group to compile the first draft of the Consensus.From January to March 2024,20 experts in the clinical nursing,nursing management,clinical medicine and other fields of congenital heart disease were solicited through 2 rounds of Delphi,and 8 experts were invited to conduct a validation to revise the items to form the final Consensus.Results The recovery rates of the 2 rounds of questionnaires were 100％;the experts'authority coefficient was 0.89;the Kendall's W were 0.172,0.211,with statistical significance(P＜0.05).The Consensus included 8 first-level subjects,namely prenatal examination and consultation,postpartum screening,standardized referral,preoperative nursing,intraoperative nursing,postoperative nursing,other disease screening,health education and discharge follow-up.Conclusion The Consensus is scientific and rigorous,and it can provide a reference basis for clinical nursing staff to carry out the care and management of newborns with congenital heart disease.
