Objective:To analyze the changes in service efficiency and cost structure before and after implementing multidisci-plinary treatment in the GD19(appendectomy with perforation,suppuration,gangrene,etc.)and GD29(appendectomy)groups of pedi-atric specialty medical institutions.Methods:The case data of GD19 and GD29 groups of medical insurance patients in sample hospi-tals in Beijing from 2021 to 2022 were collected.Mann Whitney U test was used to analyze the changes of medical expenses and effi-ciency indicators,and intermittent time series model was established to analyze the change trend.Results:Compared to 2021,the av-erage hospitalization expenses of GD19 group in 2022 decreased by 2 462.00 yuan year-on-year,and that of GD29 group decreased by 2 042.60 yuan year-on-year(P＜0.05).Among them,the cost of medicines,consumables,examinations and tests and treatment have all decreased.In the month when the management measures were implemented,the average consumption cost of GD19 group de-creased by 920.00 yuan(P＜0.05),and the average consumption cost of GD29 group decreased by 632.50 yuan.The average length of stay in GD29 group decreased from 3.74 days to 2.78 days(P＜0.05).Conclusion:After the implementation of management mea-sures,the cost of drug consumables in GD19 group and GD29 group was controlled,the cost level was reduced,and the operation effi-ciency was improved.It is suggested to adhere to the management measures of selection of key DRG groups and multidisciplinary con-sultation,mobilize the management enthusiasm of clinical departments,and strengthen the demonstration and optimization of pediatric DRG grouping and payment scheme.

Objective To investigate the noninvasive indicators of indications for antiviral therapy in HBeAg-negative chronic hepatitis B virus (HBV) infection patients with alanine aminotransferase (ALT) ≤40 U/L under the guidance of liver pathology. MethodsA retrospective analysis was performed for the clinical data of 377 HBeAg-negative chronic HBV infection patients with ALT ≤40 U/L who were hospitalized in Affiliated Hospital of Yan’an University, from October 2013 to August 2018 and underwent liver biopsy, among whom the patients with inflammatory activity ＜A2 and fibrosis stage ＜F2 were enrolled as non-antiviral therapy group(n=266), and the patients with inflammatory activity ≥A2 or fibrosis stage ≥F2 were enrolled as antiviral therapy group(n=111). The chi-square test was used for comparison of categorical data between two groups; the t-test was used for comparison of normally distributed continuous data between two groups, and the Mann-Whitney U test was used for comparison of non-normally distributed continuous data between two groups; univariate and multivariate binary logistic regression analyses were used to screen out the influencing factors for the initiation of antiviral therapy; the receiver operating characteristic (ROC) curve was plotted to evaluate the diagnostic efficiency of each indicator in determining the need for antiviral therapy in HBeAg-negative chronic HBV infection patients with ALT ≤40 U/L. ResultsOf all 377 patients, 266 (70.6%) did not need antiviral therapy for the time being, and 111 (29.4%) had marked liver damage and thus needed active antiviral therapy. The multivariate analysis showed that liver stiffness measurement (LSM) (odds ratio ［HR］=2.003, 95% confidence interval ［CI］: 1.647-2.437, P＜005), HBsAg (HR=1.563, 95% CI: 1.110-2.200, P＜0.05), HBV DNA (HR=1.519, 95% CI: 1173-1.966, P＜0.05), and albumin (HR=0.939, 95% CI: 0.884-0.998, P＜0.05) were independent influencing factors for the initiation of antiviral therapy. The ROC curve analysis showed that the area under the ROC curve (AUC) was 0.749 (95% CI: 0.699-0799) for LSM, 0642 (95% CI: 0.586-0.699) for HBV DNA, and 0.565 (95% CI: 0.507-0.623) for HBsAg, and the combination of LSM, HBV DNA, and HBsAg had a larger AUC of 0.779 (95% CI: 0.732-0.827). ConclusionThe levels of LSM, HBV DNA, and HBsAg have a reference value in determining the initiation of antiviral therapy in HBeAg-negative chronic HBV infection patients with ALT≤40 U/L.

Hepatocellular carcinoma (HCC) is one of the most common malignant tumors in the world. At present, the treatment methods for HCC mainly include surgical treatment, local regional treatment, radiotherapy, systematic treatment, and traditional Chinese medicine treatment. This article introduces the indications for surgical treatment, surgical procedures, and the advantages of postoperative adjuvant therapy, analyzes the indications for liver transplantation and its future application in clinical practice, and describes the basic principles, optimal indications, and technical advantages of mature and new ablation techniques at present. It is pointed out that for patients with early-stage HCC, the advantages and shortcomings of each treatment regimen should be fully understood to select a precise treatment regimen.

At present, hepatitis B virus (HBV) infection is recognized as an important risk factor for hepatocellular carcinoma (HCC) in the world; however, during the development and progression of hepatitis B, liver cirrhosis, and liver cancer, other factors may promote the development of HCC independently or synergistically with HBV, such as sex, age, family history, alanine aminotransferase/aspartate aminotransferase, smoking and drinking history, metabolic syndrome, and HCV or HIV infection. This article reviews the research advances in the risk factors associated with HCC.

To investigate the value of liver stiffness measurement (LSM) in the diagnosis of liver fibrosis degree in HBeAg-positive patients with chronic HBV infection. Methods A retrospective analysis was performed for the clinical data of 330 HBeAg-positive patients with chronic HBV infection who were hospitalized in Affiliated Hospital of Yan’an University from October 2013 to August 2018 and underwent liver biopsy, and according to liver pathological results, these patients were divided into mild liver fibrosis group (F0-F1) and significant liver fibrosis group (F2-F4). The t-test or the Mann-Whitney U test was used for comparison of continuous data between two groups, and the chi-square test was used for comparison of categorical data between two groups. Univariate and multivariate analyses were performed to screen out the indices for the diagnosis of significant liver fibrosis, and the receiver operating characteristic (ROC) curve was plotted for these indices to evaluate their value in the diagnosis of significant liver fibrosis. Results Of all 330 patients, 245 had mild liver fibrosis and 85 had significant liver fibrosis. There were significant differences between the two groups in HBV DNA, HBsAg, HBeAg, HBcAb, alanine aminotransferase, aspartate aminotransferase, total bilirubin, and LSM (all P＜0.05). The multivariate analysis showed that HBsAg and LSM were independent risk factors for significant liver fibrosis (both P＜0.05). The ROC curve analysis showed that only LSM had a diagnostic value, with an area under the ROC curve of 0.744 (95% confidence interval: 0.680-0.808). At the optimal cut-off value of 6.15 kPa, LSM had a sensitivity of 62.4%, a specificity of 76.3%, an accuracy of 72.1%, a positive predictive value of 72.5%, and a negative predictive value of 67.0% in predicting significant liver fibrosis. ConclusionLSM has a good value in predicting significant liver fibrosis in HBeAg-positive patients with chronic HBV infection.

Objective To research the performance of direct settlement for allopatry medical insurance at a tertiary specialized children′s hospital in Beijing, and to analyze the basics of these inpatients and the structural characteristics of their diseases, for basis and suggestions for improving the policy of direct settlement of allopatry medical insurance. Methods A statistical description of direct settlement data was made for allopatry medical insurance at this hospital from August 2017 to July 2018, to study the age, hometown, attribute, distribution of inpatient departments and disease distribution of these children. Results The patients mainly came upon referrals, preschool children in most cases. The average daily hospitalization cost of the disease was high relatively, and the number of hospitalizations was high as well. Compared with children inpatients in Beijing, these patients tend to come for surgical treatment for malignant tumors and congenital diseases.Conclusions The allopatry direct settlement of children′s medical insurance settlement is found mostly with diseases those are complicated and severe. The management of such settlement can be improved by cooperating with their local institutions in advance, data checking in the course, simplifying the formalities for special diseases, and the differential reimbursement ratio for these patients.

Objective To investigate the differences of distribution characteristics and risk factors of large artery lesions in patients with ischemic cerebrovascular disease in different age groups in order to provide the basis for the prevention and treatment of stroke in different age groups.Methods From June 2015 to May 2016,a total of 10 711 consecutive inpatients with transient ischemic attack (TIA) and ischemic stroke from 20 centers nationwide were enrolled.Each 10 years was used as an age group from 40 years.All the patients were divided into 5 age groups.The differences of the different risk factors for cerebrovascular disease among the 5 groups were compared.All patients were separated by gender.The chi square test was used to compare the incidences of large artery stenosis of the intracranial and external and anterior and posterior circulation,and the number of vascular lesions in the same sex in different age groups.Results (1) The risk factors of elderly patients were mainly hypertension,diabetes mellitus,and atrial fibrillation (χ2=61.938,χ2=13.349,and χ2=55.940;all P<0.01).The smoking history,family history of cerebrovascular disease,and obesity were more frequent among the young and middle-aged people (χ2=131.505,χ2=7.298,and χ2=100.911,all P<0.01).(2) The linear trend chi square test results showed that the proportion of multivessel diseases in female and male extracranial arterial lesions increased gradually with the increase of age.(χ2=54.799,χ2=161.370,all P<0.01).The proportion of multivessel diseases in the intracranial artery in female decreased gradually (χ2=5.328,P=0.021),and that in male did not have obvious trend of change (χ2=0.289,P=0.591).(3) The linear trend chi square test results showed that the incidence of simple intracranial arterial stenosis in female and male intracranial arterial stenosis decreased gradually with the increase of age (χ2=20.090,χ2=42.351,all P<0.01),and the incidence of simple extracranial arterial stenosis increased gradually (χ2=40.311,χ2=90.698,all P<0.01).The incidence of both intracranial and extracranial artery stenoses increased gradually (χ2=12.077,χ2=45.887,all P<0.01).The incidence of simple posterior circulation vascular stenosis increased gradually in female (χ2=16.434,P<0.01),but that did not have obvious trend of change in male (χ2=1.701,P=0.192).The incidence of stenosis of both anterior and posterior arteries in female and male increased gradually (χ2=4.587,P=0.032;χ2=35.156,P<0.01).Conclusions The distribution of atherosclerotic lesions in ischemic cerebrovascular disease of the different age groups was different.No matter female or male patients,the majority of the young and middle-aged patients were intracranial artery lesions,and the elderly patients were mainly extracranial artery lesions.The majority of elderly women had posterior circulation artery lesions.Understanding the characteristics in patients with intracranial arterial lesion in different age groups will help to develop individualized stroke prevention and treatment strategies for the population of different age groups.

Objective To understand the influence of the disease-based hierarchical medical system on inpatients flow covered by the new rural cooperative medical system ( NRCMS) , and that on the funding diversion and medical costs so incurred. Methods One county was selected from the eastern, central and western regions of China respectively, where the disease-based hierarchical medical system has been in place. Policy documents of the three counties were reviewed to analyze such changes as NRCMS inpatients flow, inpatients subsidy diversion, NRCMS fund surplus rate of the current year and medical costs per hospitalization before and after the system was in place. Results A comparison with 2014 found a 1. 26%drop of the out-of-county inpatients of county W of the western region, a 2. 00% increase of township hospitals inpatients of county D in the middle region, and the same ratio of out-of-county and in-county inpatients in county F of the eastern region in 2015. Compared with 2014, the fund surplus rate of county W increased 10. 46%, and the inpatient subsidy ratio of county D decreased 2. 51% for those in out-of-county medical institutions in 2015. Thanks for the quota payment of specific diseases under global budget in county W, the inpatient medical costs per hospitalization dropped at both county and township medical institutions. Conclusions The disease-based hierarchical medical system could optimize the NRCMS inpatients distribution among various medical institutions, conducive for establishment and operation of such a system.
