Objective To explore and implement a differentiated management strategy for multi-campus hospitals to improve patient experience and satisfaction,and achieve the goal of homogenized management.Methods In December 2021,the Picker Patient Experience Questionnaire was used to survey the patient experience at 3 campuses of a tertiary A hospital in Hangzhou,and the reasons for the differences were analyzed.Based on policy document reviews,special group discussions,and expert meetings,differentiated management strategy for multi-campus hospitals was formulated.The patient experience and satisfaction before(December 2021)and after(December 2023)the implementation were compared.Results After the application of the one-hospital multi-campus difference management strategy,the overall medical experience score of the patients in the 3 campus was(58.54±2.36)points,which was higher than(58.13±3.24)points before the application(t=-3.223,P=0.001),and there was no statistically significant differences among the patients in the 3 campuses(F=0.781,P=0.458).After the application of the management strategy,the overall satisfaction score of the patients in the 3 campus was(98.44±6.22)points,which was higher than(97.98±6.87)points before the application of the management strategy(t=-2.490,P=0.013),and there was no statistical significance among the patients in the 3 campus(F=1.128,P=0.324).The number of banners and letters of commendation received by the 3 campuses increased from 1 661 before the application to 2 190 after the application,with a growth rate of 31.85％.Conclusion Differentiated management in a multi-campus hospital,aiming at homogenized quality through differentiated strategies,is practicable and can significantly improve the patient experience and satisfaction across different campuses.

Objective:To explore the risk stratification value of HEART score combined with cardiac troponin (cTn) in emergency patients with chest pain.Methods:A total of 11 583 patients with chest pain who visited the Emergency Department of Zhongshan Hospital Affiliated to Fudan University from January to December 2019 were retrospectively collected. Patients who unfinished 0 h high-sensitivity cardiac troponin T (hs-cTnT) or electrocardiogram diagnosed ST-segment elevation myocardial infarction (STEMI) or lost to follow-up were excluded, and 7 057 patients were finally included. The final diagnosis of chest pain and the occurrence of major adverse cardiovascular events within 6 mon (6 m MACEs) were followed up by telephone and medical history. The HEART score of each patient was calculated by two attending physicians, and the patients were divided into the low-risk group (0-3 points), intermediate-risk group (4-6 points) and high-risk group (7-10 points) according to the final score. The risk stratification performance and safety of HEART score were observed and analyzed. A total of 1 884 patients who completed serial hs-cTnT tests were divided into groups according to HEART score (≤3 as low-risk group) and HEART score combined with serial hs-cTnT pathway (HEART score ≤3 and two hs-cTnT measurements <0.03 ng/mL as the low-risk group). The sensitivity (SE), specificity (SP), positive predictive value (PPV) and negative predictive value (NPV) of each diagnostic method were calculated to compare the diagnostic performance of the two predictive values.Results:The patients were divided into 3 groups by HEART score : 2 765 (39.2%) patients in the low-risk group, 3 438 (48.7%) in the intermediate-risk group, and 854 (12.1%) in the high-risk group. The incidence of 6 m MACEs in each group was 1.2%, 18% and 55.3%, respectively. When the low-risk threshold was 2, 23.1% of patients entered the low-risk group and the incidence of 6 m MACEs was 0.9%. The receiver operating characteristic (ROC) curve was drawn to evaluate the predictive performance of the HEART score for 6 m MACEs, and the final AUC was 0.831 ( P=0.006, 95% CI: 0.819-0.843). Regarding the occurrence of NSTEMI at the time of this visit, 4 (0.8%) patients were misdiagnosed by using the HEART score alone. Combined with serial troponin detection, the diagnostic SE and NPV were both 100%; at the same time, the diagnostic SE and NPV of 6 m MACEs in patients increased from 98.1% (95% CI: 96.9%-99.1%), 97.9% (95% CI: 96.2%-99%) to 99.1% (95% CI: 97.9%-99.7%) and 98.9% (95% CI: 97.4%-99.6%), the diagnosis SE and NPV of 6 m myocardial infarction and cardiac death in patients increased from 98% (95% CI: 96%-99.2%), 98.6% (95% CI: 97%-99.4%) to 99.2% (95% CI: 97.6%-99.8%) and 99.3% (95% CI: 98.1%-99.9%). Conclusions:The HEART score can be used for risk assessment in emergency patients with chest pain, and a threshold of 2 is recommended for the low-risk group. The diagnostic performance of HEART score combined with serial cTn is better than that of HEART score alone.

Objective:To investigate the clinical characteristics of patients with acute aortic dissection (AAD) through a retrospective and observational study, and to construct an early warning model of AAD that could be used in the emergency room.Methods:The data of 11 583 patients in the Emergency Chest Pain Center from January to December 2019 were retrospectively collected from the Chest Pain Database of Zhongshan Hospital Affiliated to Fudan University. Inclusion criteria: patients with chest pain who attended the Emergency Chest Pain Center between January and December 2019. Exclusion criteria were 1) younger than 18 years, 2) no chest/back pain, 3) patients with incomplete clinical information, and 4) patients with a previous definite diagnosis of aortic dissection who had or had not undergone surgery. The clinical data of 9668 patients with acute chest/back pain were finally collected, excluding 53 patients with previous definite diagnosis of AAD and/or without surgical aortic dissection. A total of 9 615 patients were enrolled as the modeling cohort for early diagnosis of AAD. The patients were divided into the AAD group and non-AAD group according to whether AAD was diagnosed. Risk factors were screened by univariate and multivariate logistic regression, the best fitting model was selected for inclusion in the study, and the early warning model was constructed and visualized based on the nomogram function in R software. The model performance was evaluated by accuracy, specificity, sensitivity, positive likelihood ratio and negative likelihood ratio. The model was validated by a validation cohort of 4808 patients who met the inclusion/exclusion criteria from January 2020 to June 2020 in the Emergency Chest Pain Center of the hospital. The effect of early diagnosis and early warning model was evaluated by calibration curve.Results:After multivariate analysis, the risk factors for AAD were male sex ( OR=0.241, P<0.001), cutting/tear-like pain ( OR=38.309, P<0.001), hypertension ( OR=1.943, P=0.007), high-risk medical history ( OR=12.773, P<0.001), high-risk signs ( OR=7.383, P=0.007), and the first D-dimer value ( OR=1.165, P<0.001), Protective factors include diabetes( OR=0.329, P=0.027) and coronary heart disease ( OR=0.121, P<0.001). The area under the ROC curve (AUC) of the early diagnosis and warning model constructed by combining the risk factors was 0.939(95 CI:0.909-0.969). Preliminary validation results showed that the AUC of the early diagnosis and warning model was 0.910(95 CI:0.870-0.949). Conclusions:Sex, cutting/tear-like pain, hypertension, high-risk medical history, high-risk signs, and first D-dimer value are independent risk factors for early diagnosis of AAD. The model constructed by these risk factors has a good effect on the early diagnosis and warning of AAD, which is helpful for the early clinical identification of AAD patients.

Objective:To analyze the clinical features of patients with pyogenic liver abscess (PLA) and the application of mNGS in PLA, thus to provide reference for clinical diagnosis and treatment.Methods:The demographic and clinical data of 549 patients with liver abscess admitted to Zhongshan Hospital Affiliated to Fudan University from December 2015 to June 2020 were analyzed retrospectively. According to the detection of Klebsiella pneumoniae in 246 patients with positive etiological test results, the patients were divided into two groups: KPLA group and nKPLA group, and clinical characteristics of the two groups were compared. At the same time, the application value of mNGS in PLA was analyzed.Results:Among the 549 patients, the main clinical symptom of PLA was fever ( n= 503, 91.6%) and other clinical symptoms included chills and abdominal pain. Most patients had a single abscess ( n= 464, 84.5%) located in the right lobe ( n = 368, 67.0%), with a size between 5 and 10 cm ( n= 341, 62.1%). A total of 246 patients had positive etiological test results, including 202 KPLA patients which was the main pathogen of liver abscess. The prevalence of diabetes and fatty liver was higher in KPLA patients ( P < 0.05), but there were more culture of liver positive factors in nKPLA patients ( P < 0.001). Among the 109 patients with traditional microbiological results, 92 patients were suspected to KPLA (Klebsiella pneumoniae), of which 14 patients (15.2%) were multidrug resistant (MDR) infection; 17 patients were suspected to nKPLA, of which 10 patients (58.8%) were MDR infection; the incidence of MDR infection in patients with nKPLA was significantly higher than that in patients with KPLA ( P < 0.05). The positive rate of mNGS in plasma was 85.2%, the positive rate of traditional microbial culture in plasma was 14.8%, the positive rate of mNGS in pus was 96.2% and traditional microbial culture in pus was 65.4%. The positive rate of traditional culture was significantly lower than that of mNGS ( P < 0.05). Conclusions:PLA is usually manifested as fever, single and at the right lobe of the liver. Klebsiella pneumoniae is the most common pathogenic bacteria of PLA, which is more common in patients with diabetes and fatty liver, while non-Klebsiella pneumoniae is relatively more common in patients with culture of liver positive factors. The positive detection rate of mNGS is high, which has a unique advantage in pathogen detection.

Objective To understand the epidemiological characteristics of acute respiratory virus infection in hospitalized patients, and to provide reference for clinical diagnosis and treatment, and to develop relevant intervention measures. Methods A total of 414 hospitalized patients with respiratory virus infection admitted to our hospital from March 2019 to March 2021 were selected. Immunofluorescence method was used to qualitative detect parainfluenza virus type 1-3, influenza A virus, respiratory syncytial virus (RSV), influenza B virus and adenovirus. Results Among the 414 ARTI patients, 84 cases were positive for respiratory virus, with a positive detection rate of 20.29% (84/414 ) . 76 cases were positive for single virus infection, with a positive detection rate of 18.36% (76/414) . The positive detection rate was 1.93% (8/414). The most common pathogens of virus infection were influenza A virus (25.00%), influenza B virus (20.23%) and RSV(17.86%). There was statistical significance in the positive rate of ARTI among different age groups (χ², P<0.05). The positive rate of respiratory virus in 1-8 years group was the highest (38.93%). There was statistical significance in the positive rate of 7 viruses (P<0.05). The patients with viral mixed infection were mainly children under 8 years old; There was statistical significance in the positive rate of ARTI in different seasons (χ², P<0.05). There was no significant difference in the seasonal distribution of PIV1, PIV2, ADV and mixed infection rates ( P>0.05). The positive rate of PIV3 was the highest in spring (4.04%), and the positive rate of RSV in spring and winter was 24.24% and 25.20%, respectively. The positive rates of influenza A virus and influenza B virus were the highest in winter (9.45%) and (7.09%). There was statistical significance in the positive rate of ARTI among different clinical diagnoses (χ², P<0.05). The positive rates of PIV2, PIV3, influenza A virus and influenza B virus were significantly different (P<0.05). The positive rate of bronchopneumonia virus was the highest (27.48%). Conclusion: RSV infection is the most common in patients with acute respiratory virus infection in Chengdu area, which mostly occurs in autumn and winter, and the main clinical manifestation is bronchopneumonia. The main infected population is children under 8 years old, and the surveillance of respiratory syncytial virus should be strengthened in the future.

Objective:To analyze the prognostic risk factors of patients with sepsis and the clinical characteristics of patients with septic myocardial injury.Methods:A retrospective study was conducted. The clinical data of 300 patients with sepsis admitted to emergency department of Zhongshan Hospital of Fudan University from September 2017 to June 2020 were enrolled, including basic information, blood test indicators and auxiliary inspection indicators. The patients were grouped according to myocardial injury and the clinical characteristics of patients with septic myocardial injury were analyzed. According to 28-day prognosis, they were divided into survival group and non-survival group. The differences in various indicators between the two groups were compared, and binary Logistic regression was used to explore independent risk factors for death in patients with sepsis.Results:In 300 patients, 47 patients were excluded for previous heart disease or lack of the main inspections, and 253 patients were enrolled finally. ① Myocardial injury occurred in 136 out of 253 patients (53.8%), and 117 without myocardial injury. Compared with the non-myocardial injury group, the myocardial injury group had higher blood white blood cell count [WBC (×10 9/L): 9.7 (6.7, 13.4) vs. 8.3 (5.4, 12.2)] and procalcitonin [PCT (μg/L): 0.61 (0.18, 4.63) vs. 0.23 (0.09, 0.99)] at admission, and more Staphylococcal infections (17.6% vs. 2.6%), more arrhythmia (sinus tachycardia: 30.9% vs. 23.1%), more ST-T changes (26.5% vs. 23.1%), lower left ventricular ejection fraction [LVEF: 0.60 (0.54, 0.65) vs. 0.62 (0.60, 0.66)], higher pulmonary artery systolic pressure [PASP (mmHg, 1 mmHg = 0.133 kPa): 38.0 (32.2, 46.0) vs. 33.0 (30.0, 40.2)], and worse prognosis (28-day mortality: 44.1% vs. 6.0%, all P < 0.05). Logistic regression analysis showed that PCT increased [odds ratio ( OR) = 1.039, 95% confidence interval (95% CI) was 1.018-1.060, P < 0.01], LVEF decreased ( OR = 0.828, 95% CI was 0.729-0.941, P < 0.01) and sinus tachycardia ( OR = 3.512, 95% CI was 1.417-8.702, P < 0.01) were clinical characteristics of septic patients with myocardial injury. ② A total of 186 of the 253 patients survived, and 67 died with 28-day mortality of 26.5%. Compared with the survival group, non-survival group had higher myocardial markers and inflammation markers at admission [cardiac troponin T (cTnT, μg/L): 0.06 (0.02, 0.17) vs. 0.02 (0.01, 0.05), N-terminal pro-brain natriuretic peptide (NT-proBNP, ng/L): 3 037.0 (1 308.7, 12 033.7) vs. 893.9 (272.8, 2 825.5), creatine kinase (CK, U/L): 144.5 (57.5, 660.8) vs. 89.5 (47.8, 201.0), WBC (×10 9/L): 10.5 (6.7, 14.6) vs. 8.6 (6.0, 12.0), C-reactive protein (CRP, mg/L): 89.2 (54.8, 128.5) vs. 63.8 (19.3, 105.6), PCT (μg/L): 2.13 (0.31, 11.79) vs. 0.28 (0.10, 1.25), all P < 0.05], and more sinus tachycardia and atrial arrhythmia (41.8% vs. 22.0%, 29.9% vs. 17.7%, both P < 0.05). Logistic regression analysis showed that cTnT increased ( OR = 2.115, 95% CI was 1.189-5.459, P < 0.05), sinus tachycardia ( OR = 2.557, 95% CI was 1.103-5.929, P < 0.05) and atrial arrhythmia ( OR = 2.474, 95% CI was 1.025-5.969, P < 0.05) were independent risk factors for 28-day death in patients with sepsis. Conclusions:Myocardial injury is an independent risk factor for death in patients with sepsis. PCT elevation, LVEF decreased and sinus tachycardia are main characteristics of patients with septic myocardial injury, which should attract clinical attention.

Objective:To compare the predictive value of the HEART, TIMI and GRACE scores for major adversecardiovascular events (MACEs) at 7 and 28 days in patients with actue non-ST-segment elevation myocardial infarction (NSTEMI).Methods:More than 12 000 patients with chest pain from the Emergency Department of Zhongshan Hospital Affiliated to Fudan University from October 2017 to October 2018 were studied, including 566 patients with cardiogenic chest pain, 105 patients with ST-segment elevation myocardial infarction (STEMI) excluded and 15 patients lost to follow-up. Finally, 109 patients with NSTEMI and 337 non-myocardial patients with cardiogenic chest pain were enrolled. NSTEMI patients were divided into subgroups according to whether MACEs occurred. LSD t-test, Mann-Whitney U test or χ2 test were used to analyze and compare the differences between the two subgroups about the baseline data, clinical data, HEART, TIMI and GRACE scores at the time of visit. Multivariate logistic regression analysis was used to explore the independent factors of MACEs at 7 and 28 days. And the predictive values of different scores for 7-day MACEs and 28-day MACEs were compared in NSTEMI patients through the receiver operating characteristic (ROC) curve. Results:Compared NSTEMI patients with non-myocardial patients with cardiogenic chest pain, we found a statistically significant differences in sex, past history of coronary heart disease,≥3 risk factors for atherosclerosis, electrocardiogram, high-sensitivity troponin T (hs-cTnT), creatinine value, past history of myocardial infarction, HEART score, TIMI score and GRACE score. In further subgroup analysis of NSTEMI patients who were divided according to whether MACEs occurred, we found previous history of stroke and increased hs-cTnT were statistically different in 7 days after the onset of the disease. The multivariate analysis showed that the previous history of stroke and increased hs-cTnT were independent factors for the occurrence of MACEs at 7 days after the onset of NSTEMI; The previous history of stroke and increased hs-cTnT, electrocardiogram ST segment depression and TIMI score were statistically different at 28 days after the onset of NSTEMI. The multivariate analysis showed that the previous history of stroke and TIMI score were independent factors for the occurrence of MACEs at 28 days after the onset of NSTEMI patients. ROC curve indicated that the predictive value of TIMI score (AUC=0.715, 95% CI: 0.482-0.948) was better than HEART (AUC=0.659, 95% CI: 0.414-0.904) and GRACE scores (AUC=0.587, 95% CI: 0.341-0.833)in predicting MACEs in NSTEMI patients. Conclusions:HEART score, TIMI score and GRACE score can be used to evaluate NSTEMI patients. There is an independent predictive value on TIMI score for the occurrence of 28-day MACEs in NSTEMI patients.

OBJECTIVES: The effects of hormone replacement therapy on the survival rate of female lung cancer patients are still controversial. The Meta-analysis aims to systematically evaluate the effect of hormone replacement therapy on the survival rate of female lung cancer patients. METHODS: Retrospective studies regarding the effect of hormone replacement therapy on female lung cancer patients' survival rate were searched from the database of Embase, Cochrane, Pubmed, CNKI, Wanfang, and Weipu. The Meta-analysis was conducted with Stata 12.0 software. test was used to analyze the heterogeneity among included studies. The analysis was conducted by randomized model. Egger's test and Begg's test were used to assess the publication bias. RESULTS: Five retrospective studies were included, involving 2 582 female patients with lung cancer. There were 1 054 cases of female lung cancer with hormone replacement therapy and 1 528 cases of female lung cancer without hormone replacement therapy. No publication bias was observed among these studies. The sensitivity analysis result showed that the overall results were stable. Meta-analysis showed that compared with patients without hormone replacement therapy, patients with hormone replacement therapy had an increased survival time for 5 years (ES=0.346; 95% CI 0.216 to 0.476; <0.001). CONCLUSIONS Hormone replacement therapy improves 5-year survival in female lung cancer patients. Female lung cancer patients with menopausal syndrome can use hormone replacement therapy properly under their doctors' suggestion.

Objective To investigate the early diagnostic and prognostic value of plasma D-dimer level in acute aortic dissection.Method Data of totally 500 acute chest pain patients were studied,in which 250 cases were in group of acute aortic dissection (group AAD) confirmed by aortic computerized tomographic angiography (CTA) or cardiac ultrasonography,and the rest 250 cases were in non AAD group (group control).The D-dimer test was performed in all patients within 72 hours after onset of chest pain,and comparison of plasma D-dimer concentration was carried out between two groups.The D-dimer diagnostic value in AAD was analyzed by plotting the receiver operating characteristic (ROC) curve.According to AAD patients with aortic CTA findings,the whole aortic artery was divided into four segments by the major vascular branches,and the false lumen area was measured by degree score,the relationship between the score and D-dimer level were analyzed.To study the prognostic value of D-dimer in AAD,the comparison of D-dimer level was carried out between survival group and death group,and the AAD patients were further stratified by the surgery and Stanford type.Results The plasma D-dimer concentrations in AAD group were significantly higher than those in controls (P ＜0.01).The sensitivity,specificity,positive predictive value and negative predictive value of D-dimer (＞ 1.14 mg/L) in the diagnosis of AAD were 81.2％,79.39％,74.63％ and 72.4％ respectively,and the area under the ROC curve was 0.083.The elevated level of D-dimer was positively correlated with the extent of AAD false lumen (Spearman-Rho =0.418,P ＜ 0.01).D-dimer levels in the death group were higher than those in the survival group.Conclusions D-dimer may be a valuable biomarker in early diagnosis of AAD.The elevated level of D-dimer was useful to evaluate the extent of the dissection and prognosis of AAD.

Objective: To explore the imaging manifestations of multi-slice spiral CT angiography (CTA) and relationship with in-hospital death in patients with aortic dissection (AD). Methods: The clinical data of 429 patients with AD who underwent CTA in Zhongshan Hospital of Fudan University between January 2009 and January 2016 were retrospectively analyzed. AD patients were divided into 2 groups, including operation group who underwent surgery or interventional therapy (370 cases) and non-operation group who underwent medical conservative treatment(59 cases). The multi-slice spiral CTA imaging features of AD were analyzed, and multivariate logistic regression analysis was used to investigate the relationship between imaging manifestations and in-hospital death in AD patients. Results: There were 12 cases (3.24%) of in-hospital death in operation group, and 28 cases (47.46%) of in-hospital death in non-operation group(P<0.001). AD involved different vascular branches. Multi-slice spiral CTA can clearly show the dissection of true and false lumen, and intimal tear was detected in 363 (84.62%) cases, outer wall calcification was revealed in 63 (14.69%) cases, and thrombus formation was present in 227 (52.91%) cases. The multivariate logistic regression analysis showed that the number of branch vessels involved (OR=1.374, 95%CI 1.081-1.745, P=0.009) and tearing false lumen range(OR=2.059, 95%CI 1.252-3.385, P=0.004) were independent risk factors of in-hospital death in AD patients, and the number of branch vessels involved (OR=1.600, 95%CI 1.062-2.411, P=0.025) was independent risk factor of in-hospital death in the operation group, while the tearing false lumen range (OR=2.315, 95%CI 1.019-5.262, P=0.045) was independent risk factor of in-hospital death of non-operation group. Conclusions Multi-slice spiral CTA can clearly show the entire AD, true and false lumen, intimal tear, wall calcification and thrombosis of AD patients. The number of branch vessels involved and tearing false lumen range are the independent risk factors of in-hospital death in AD patients.
