Objective:To construct an evaluation indicator system for the efficiency of nursing human resources in integrated medical and elderly care institutions using Data Envelopment Analysis (DEA) and subsequently evaluate its effectiveness.Methods:This cross-sectional survey utilized literature review and investigative methods to initially establish a library of evaluation indicators for nursing human resource efficiency. The Delphi method was employed in two rounds of consultations with 17 experts from various fields, including nursing management, elderly care institution management, integrated medical and elderly care institution management, health economics management, and public health. The reliability of the indicator system was assessed based on factors such as expert enthusiasm, authority, concentration of opinions, and coordination. Adjustments, modifications, and improvements were made to the indicators based on expert opinions to establish the final indicator system. From August to December 2022, the DEA model was applied to evaluate the efficiency of 12 integrated medical and elderly care institutions in Haikou city based on this indicator system.Results:The constructed evaluation indicator system comprised 68 items divided into three levels: 9 primary indicators, 19 secondary indicators, and 40 tertiary indicators. The positive coefficients of the two rounds of expert consultations were 100% and 94.1%, with authority coefficients of 0.88 and 0.92, Kendall harmony coefficients of 0.471 and 0.348, and mean coefficients of variation of 0.16 and 0.12 ( P<0.001). DEA evaluation results for the 12 integrated medical and elderly care institutions showed that 5 were DEA effective institutions with comprehensive efficiency (OE), technical efficiency (TE), and scale efficiency (SE) values all equal to 1.000, while 7 were non-DEA effective institutions, including 4 with SE <1.000 but TE=1.000 and 3 with both SE and TE<1.000. Conclusions:The constructed evaluation indicator system demonstrates high enthusiasm, authority coefficients, and coordination in expert consultations, indicating high acceptability and comprehensive content with distinct levels and strong specialty characteristics. The DEA model′s evaluation results objectively and effectively reflect the efficiency of nursing human resources in integrated medical and elderly care institutions, demonstrating practical utility.

Objective:To investigate the influencing factors of increased tube bleeding within 24 h after coronary artery bypass grafting(CABG) and its correlation with perioperative complications.Methods:This study was a prospective observational study. The patients with CABG surgery were enrolled in Beijing Anzhen Hospital affiliated to Capital Medical University from May 2018 to December 2021. The age, sex, complications, blood tests and other clinical data of outpatients were collected. Left ventricular ejection fraction(EF) and left ventricular enddiastolic diameter(LVED) were detected by echocardiography. MGF and PI of grafts were recorded during CABG. Perioperative troponin Ⅰ, blood clotting pentathlon, all-cause death, perioperative myocardial fraction, atrial fibrillation and stroke were collected. According to the tube bleeding within 24 h after operation, the patients were divided into increased group(tube bleeding>1 000 ml) and normal group(tube bleeding≤1 000 ml). The preoperative baseline data, intraoperative indexes and perioperative complications were compared between the two groups. Logistic regression, Spearman and linear regression models were used to analyze the correlation between tube bleeding within 24 h and clinical data.Results:304 patients underwent CABG were enrolled. There were 185 cases(60.9%) in the increased group and 119 cases(39.1%) in the normal group. After adjusting for age, sex and BMI, multivariate logistic regression analysis showed that male( OR=2.40, 95% CI: 1.38-4.18, P=0.002), history of stroke( OR=2.37, 95% CI: 1.07-5.26, P=0.034), and history of myocardial infarction( OR=1.81, 95% CI: 1.13-2.91, P=0.014) could significantly increase the risk of tube bleeding within 24 h after surgery. The average blood flow of the anterior descending branch( OR=0.99, 95% CI: 0.99-1.00, P=0.022) and the circumflex branch( OR=0.99, 95% CI: 0.98-1.00, P=0.003) during the operation was significantly negatively correlated with the increase of tube bleeding within 24 h after surgery, while the PI of anterior descending branch( OR=1.81, 95% CI: 1.26-2.61, P=0.001), circumflex branch( OR=1.45, 95% CI: 1.07-1.97, P=0.017), right coronary artery( OR=1.84, 95% CI: 1.29-2.62, P=0.001) were positively correlated with the increase of tube bleeding within 24 h after operation. In addition, prothrombin time significantly increased the risk of increased tube bleeding within 24 h after surgery( OR=1.16, 95% CI: 1.03-1.30, P=0.018). Linear regression analysis showed that there was a significant positive linear correlation between ICU time and tube bleeding within 24 h after surgery( OR=0.17, 95% CI: 0.96-4.58, P=0.003), and a significant negative linear correlation between postoperative ejection fraction and tube bleeding within 24 h( OR=-0.25, 95% CI: -33.18--13.07, P<0.001). Conclusion:Increased tube bleeding within 24 h after CABG is most common in males and patients with a history of cardiovascular and cerebrovascular infarction. Better graft hemodynamic parameters can reduce the tube bleeding within 24 h after the operation, further improve cardiac function and reduce ICU time.

The treatment of acute Stanford type A aortic dissection has always been extremely challenging. Organ malperfusion syndrome is a common severe complication of acute aortic dissection, which can cause organ ischemia and internal environment disorder. Malperfusion increases early mortality, and impacts the long-term prognosis. In recent years, many scholars have done some studies on aortic dissection complicated with malperfusion. They explored the pathogenesis, proposed new classification, and innovated new treatment strategies. However, at present, the treatment strategies of acute Stanford type A aortic dissection complicated with organ malperfusion are different at different centers and consensus on its treatment is still lacking. Therefore, this review summarized the pathogenesis, classification, treatment strategy, and prognosis of acute Stanford type A aortic dissection complicated with malperfusion.

Objective To investigate the influencing factors of nosocomial pneumonia in elderly pa-tients with CHD and HF.Methods A total of 196 elderly CHD patients with HF diagnosed and treated in our department from March 2021 to August 2023 were enrolled,and divided into infec-ted group(n=52)and non-infected group(n=144)based on whether pulmonary infection oc-curred during hospitalization.Logistic regression analysis was used to identify the risk factors af-fecting secondary nosocomial pulmonary infection.Based on these risk factors,a comprehensive in-dex was built.ROC curve was drawn to analyze the diagnostic value of the index for secondary nosocomial pulmonary infection.Results The infected group had significantly advanced age,lar-ger proportions of NYHA grade Ⅲ to Ⅳ,smoking history,diabetes history,mechanical ventila-tion time＞48 h,length of hospital stay＞14 d,and albumin at admission＜30 g/L,and higher RDW at admission when compared with the non-infected group(P＜0.05,P＜0.01).Logistic regression analysis showed that NYHA grade Ⅲ to Ⅳ,diabetes history,mechanical ventilation time＞48 h,length of hospitalization＞14 d,albumin＜30 g/L at admission and RDW at admis-sion were risk factors for secondary nosocomial pulmonary infection in elderly CHD patients with HF(OR=2.398,95％CI:1.157-4.969;OR=2.732,95％CI:1.278-5.839;OR=2.607,95％CI:1.138-5.973;OR=3.368,95％CI:1.567-7.242;OR=2.677,95％CI:1.218-5.886;OR=1.762,95％CI:1.488-61.222).ROC curve analysis indicated that the AUC value of NYHA grade Ⅲ to Ⅳ,diabetes history,mechanical ventilation time＞48 h,length of hospitalization＞14 d,albumin＜30 g/L at admission and RDW at admission in predicting secondary nosocomial pulmonary infec-tion in elderly CHD patients with HF was 0.598,0.620,0.586,0.595,0.615 and 0.850,respectively,and the value of the comprehensive index was 0.743,which is superior to that of above single indi-cator(P＜0.05).Conclusion Age,NYHA grade,smoking history,diabetes history,mechanical ventilation time,hospital stay and albumin and RDW levels at admission have adverse effects on secondary nosocomial pulmonary infection in elderly CHD patients with HF.Our built compre-hensive index based on these risk factors has high efficacy in predicting nosocomial pulmonary in-fection.

Objective:To explore the organizational identity, sense of coherence, perceived social support, and work engagement of surgical nurses in a traditional Chinese medicine hospital and the relationships between them.Methods:From March to May 2022, 450 surgical nurses were selected by convenience sampling from Guangdong Provincial Hospital of Traditional Chinese Medicine for a survey with a general information questionnaire, the Organizational Identification Scale, the Sense of Coherence Scale, the Perceived Social Support Scale, and the Utrecht Work Engagement Scale-9. SPSS 24.0 was used to perform Pearson correlation analysis. AMOS 24.0 was used for structural equation modeling.Results:The nurses' scores of organizational identity, sense of coherence, perceived social support, and work engagement were (26.00±5.00), (53.58±7.50), (47.47±7.50), and (30.06±1.00), respectively. The correlation analysis revealed positive correlations between organizational identity, sense of coherence, perceived social support, and work engagement ( r=0.369-0.741, all P<0.001). Sense of coherence played a partial mediating role between perceived social support and work engagement, and the mediating effect was 0.07, accounting for 12.07% of the total effect. Organizational identity and sense of coherence produced a chain mediating effect between perceived social support and work engagement, in which the mediating effect was 0.11, accounting for 18.97% of the total effect. Conclusions:Organizational identity and sense of coherence produce a chain mediating effect between perceived social support and work engagement in the surgical nurses of the traditional Chinese medicine hospital.

Objective:To retrieve, evaluate, and summarize relevant evidence on remote pulmonary rehabilitation programs for patients with Chronic Obstructive Pulmonary Disease (COPD) .Methods:Following the 6S Pyramid Evidence Model, domestic and international guideline websites, evidence-based databases, association websites, and original databases were systematically searched for literature related to remote pulmonary rehabilitation for patients with COPD, including guidelines, expert consensus, evidence summaries, clinical decisions, practice recommendations, systematic reviews, and randomized controlled trials. The search was conducted from the databases' inception to July 31, 2023. Quality assessment and data extraction were independently conducted by two researchers.Results:A total of 27 articles were included, including five guidelines, one clinical decision, four evidence summaries, one expert consensus, 14 systematic reviews, and two randomized controlled trials. A total of 27 best evidence recommendations were synthesized across seven aspects, including setting, target population, pre-intervention preparation, communication devices, remote pulmonary rehabilitation programs, maintenance exercise plans, and remote health monitoring.Conclusions:The process of forming the best evidence for remote pulmonary rehabilitation programs for patients with COPD is comprehensive and scientific. Healthcare professionals should integrate evidence-based practice with patient preferences to develop personalized remote pulmonary rehabilitation programs according to individual circumstances.

Objective:To explore the clinical value of aspirin combined with atorvastatin in the prevention of new onset atrial fibrillation after off-pump coronary artery bypass grafting (OPCABG).Methods:208 patients with coronary artery bypass grafting in our hospital from June 2019 to June 2021 were selected as the research subjects and divided by a random number table method into groups. The control group (104 cases) was treated with aspirin before operation, and the observation group (104 cases) was treated with aspirin and atorvastatin before operation. ECG monitoring was carried out continuously for 7 days of patients in the two groups, and the occurrence and duration of AF were recorded. The clinical therapeutic efficacy, incidence and adverse reactions of AF, left atrial diameter and high-sensitivity C-reactive protein (hs-CRP) level were observed before and after treatment.Results:The incidence of AF in the observation group was significantly lower than that in the control group, the difference was statistically significant ( P<0.05). There was no statistical significant difference in the starting time of AF between the two groups after operation ( P>0.05). The duration of AF in the observation group was better than that in the control group, the difference was statistically significant ( P<0.05). Before treatment, there was no statistical significant difference in left atrial diameter and hs-CRP level between the two groups ( P>0.05). After treatment, the left atrial diameter in the observation group returned to that before treatment, and there was no statistical significant difference in the same group ( P>0.05). The left atrial diameter in the control group was higher than that before treatment, and there was statistical significant difference in the same group ( P<0.05). The level of hs-CRP was lower than that in the control group, the difference was statistically significant ( P<0.05). There were no adverse reactions in both groups. Conclusion:Aspirin combined with atorvastatin has a significant effect in preventing new onset AF after OPCABG. It can reduce the incidence of postoperative AF, shorten the duration of AF, effectively control the inner diameter of left atrium, reduce the degree of postoperative inflammatory reaction, and has no adverse effects. It is worthy of clinical application.

Objective    To systematically evaluate the risk factors for postoperative pulmonary infection in patients with esophageal cancer. Methods    CNKI, Wangfang Data, VIP, CBM, PubMed, EMbase, The Cochrane Library were searched from inception to January 2021 to collect case-control studies, cohort studies and cross-sectional studies about risk factors for postoperative pulmonary infection in patients with esophageal cancer. Two researchers independently conducted literature screening, data extraction and quality assessment. RevMan 5.3 software and Stata 15.0 software were used for meta-analysis. Results    A total of 20 articles were included, covering 5 409 patients of esophageal cancer. The quality score of included studies was 6-8 points. Meta-analysis results showed that age (MD=1.99, 95%CI 0.10 to 3.88, P=0.04), age≥60 years (OR=2.68, 95%CI 1.46 to 4.91, P=0.001), smoking history (OR=2.41, 95%CI 1.77 to 3.28, P<0.001), diabetes (OR=2.30, 95%CI 1.90 to 2.77, P<0.001), chronic obstructive pulmonary disease (OR=3.69, 95%CI 2.09 to 6.52, P<0.001), pulmonary disease (OR=2.22, 95%CI 1.16 to 4.26, P=0.02), thoracotomy (OR=1.77, 95%CI 1.32 to 2.37, P<0.001), operation time (MD=14.08, 95%CI 9.64 to 18.52, P<0.001), operation time>4 h (OR=3.09, 95%CI 1.46 to 6.55, P=0.003), single lung ventilation (OR=3.46, 95%CI 1.61 to 7.44, P=0.001), recurrent laryngeal nerve injury (OR=5.66, 95%CI 1.63 to 19.71, P=0.006), and no use of patient-controlled epidural analgesia (PCEA) (OR=2.81, 95%CI 1.71 to 4.61, P<0.001) were risk factors for postoperative pulmonary infection in patients with esophageal cancer. Conclusion    The existing evidence shows that age, age≥60 years, smoking history, diabetes, chronic obstructive pulmonary disease, pulmonary disease, thoracotomy, operation time, operation time>4 h, single lung ventilation, recurrent laryngeal nerve injury, and no use of PCEA are risk factors for postoperative pulmonary infection in patients with esophageal cancer. Due to the limitation of the quantity and quality of included literature, the conclusion of this study still needs to be confirmed by more high-quality studies.

Fibromyalgia syndrome (FMS), also known as fibromyalgia, is clinically characterized by diffuse chronic muscle and bone pain, accompanied by fatigue, sleep disturbances, depressive episodes, and cognitive and intestinal dysfunction. Due to lack of clear specific laboratory indicators and appropriate imaging examinations, FMS diagnosis is mostly based on clinical symptoms, but FMS clinical symptoms of lack specificity, and current clinical diagnostic criteria are mostly exclusive criteria, which is prone to missed diagnosis and misdiagnosis. In order to further promote the standardized diagnosis and treatment of FMS, this paper makes extensive references to laboratory-related diagnostic indexes of FMS (Tau, adiponectin, serum cathepsin S, cystatin C, serum ferritin, nitric oxide, neutrophil/lymphocyte ratio, platelet distribution width and mean platelet volume) at home and abroad, aiming to provide new ideas for early diagnosis and intervention of FMS.
