Objective To investigate the causes and preventive measures for failure and complications of minimally invasive percutaneous nephrolithotomy (mPCNL). Methods From January 2005 to October 2008,totally 353 cases of mPNCL were performed in our hospital. Among the cases,30 patients experienced failure of the surgery or postoperative complications. The data of the 30 patients were analyzed retrospectively in this study. Results Of the 30 cases,puncture failure occurred in 5 patients,while 2 of them were converted to open surgery,and the other 3 were treated by a second puncture successfully; Zebra wire extrusion was found in 5 cases,who were then cured by re-puncture or a second operation; in 3 patients,the wire or PCN tube was moved into the renal vein (2 cases) or the colon (1 case) without causing bleeding or intestinal fistula,the cases were cured afterwards by a second operation; 3 patients developed hydrothorax and then was cured by chest drainage; postoperative arteriovenous fistula was detected in 2 patients,who were cured by interventional therapy; in 5 days after the operation,one patient developed massive hemorrhage from the PCN tube when driving cars,and then recovered by clipping the PCN tube and hemostasis; another patient showed hemorrhage and infection due to extraction of the PCN tube,and open surgery was carried out to cure this patient. Conclusions Failure of puncture and Zebra wire extrusion are most common causes of failure of mPCNL. Whereas,post-mPCNL complications is often caused by unskillful surgeons or noncompliant patients.

Objective To estimate the operational efficiency of 37 county level public general hospitals in Hubei province using the world popular method of Bootstrap-data envelopment analysis.The aim is to make up for the theory and methodology gaps on DEA research for hospitals in China,and to provide policy and management recommendations for their further improvement.Methods The input and output indicators of hospital efficiency evaluation were selected based on our previous research.R Software was used to describe the current input and output indicators,while FEAR package used to measure Bootstrap-DEA efficiency value of the sample hospitals with bias corrected,along with such applied analysis as efficiency benchmarking for the technical efficiency outcomes.Results There are great differences among the healthcare input and output of these hospitals.In particular,the difference in the number of actual beds was 4.67 times between the highest hospital and the lowest one.All of the bias corrected efficiency scores were lower than those before correction,and the average bias corrected score of the sample hospitals is 0.717 9.Moreover,only 20 hospitals(54.05%)have their efficiency scores above the median level.Conclusions The healthcare resources allocation of these hospitals needs to be further optimized.Hospitals still have big potential to improve their efficiency.Besides providing policy support,the government is advised to guide hospitals to innovate their management mechanisms,such as introducing and applying benchmarking,ranking,inter-hospital learning among others,so as to continuously improve their operational efficiency.

Objectives:This study aims to summarize the research progress of multiple-site physician practice to determine further research directions. Methods:Literature on Chinese multiple-site physician practice between 1949 and 2013 was obtained from CNKI, Wan fang database and CQVIP database, the annual volume distribution of se-lected documents was been described and the topics and content of literature cited at least once were summarized through literature content analysis. Results:The volume of literature increased rapidly from 2009, guided by related government policies. Content analysis is insufficient in the research areas of supporting policies, international experi-ences, relevant laws and empirical studies. Suggestions: Further research should focus on multiple-site physician practice policies themselves and supporting policy analysis, international comparisons of multiple-site physician prac-tice systems, studies into relevant laws and regulations and empirical studies based on quantitative methods.

Objective:This study aims to ensure the private hospitals development strategy in the background of new healthcare reform and put forward some scientific suggestions to help promote their sustainable development. Methods:The SWOT analysis method was adopted to analyze the private hospitals’ internal strength, weakness, exter-nal opportunity and threats. Results: The results showed a clear property right, advanced management system and other outstanding advantages in the private hospitals. Opportunities like the improved policy environment and people’s medical demand expansion are also very prominent. Meanwhile, the private hospitals development also faces some disadvantages and challenges such as illegal operation, disorder in the market competition, vague orientation, etc. Conclusions:It suggests the strengthening of the personnel and hospital culture construction, adoption of the differen-tiation strategy, improvement of the diagnosis and treatment ability, etc.

Objective:This study aims to explore recent developments in DEA-based hospital efficiency studies in China, so as to provide reference for further research in DEA-based hospital efficiency. Methods:In this study, a 30-year retrospective systematic review is conducted for the classification of 85 hospital efficiency studies that have been published in China with DEA. The characteristics are summarized and compared with those of international liter-ature according to the selection of input and output indicators to evaluate the normalization of studies in China. Re-sults:The classification reveals several problems existing in DEA-based hospital efficiency studies in China, such as too few studies on hospital allocation efficiency, the application of simple classical models, imprecise selection of in-put-output indicators, inappropriate application of monetary variables as output indicators, etc. Conclusions and sug-gestions:The normalization and rationality of DEA methods applied in China’s hospital efficiency research need to be improved, so as to shorten the gap between China and the international world. Chinese researchers should pay more attention to studying the latest international research findings, so as to scientifically select input and output indicators. In depth analysis of methods and application conditions should be conducted so as to improve the normalization and science of China’s hospital efficiency research.

Objective To evaluate the value of acoustic radiation force impulse (ARFI) elastography in assessment of nonalcoholic fatty liver disease (NAFLD) and hepatic fibrosis in rats.Methods Models with various degrees of NAFLD severity were conducted in 110 rats by feeding high fat emulsion.The right liver lobe of rat models were processed and embedded in a fabricated gelatin solution to measure the shear wave velocity (SWV) by ARFI.And the other liver lobes were used for histologic assessment.Based on NAFLD activity score (NAS),the final pathologic NAFLD diagnosis were considered as normal group (NAS=0),simple steatosis (SS) group (1≤NAS≤2),borderline (3≤NAS≤4) group and nonalcoholic steatohepatitis (NASH) group (NAS≥5).The diagnostic accuracy of the SWV parameters in evaluating NAFLD severity and fibrosis stages was studied using ROC curves.Results The difference of SWV values among normal group,SS group,borderline group and NASH group was statistically significant (F=31.53,P＜0.001).Taking SWV≥ 2.54 m/s as the diagnostic standard to differentiate normal rats from rats with SS,and SWV≥2.90 m/s to differentiate SS from NASH in rats,the area under ROC curve (AUC) was 0.922 (95％CI [0.871,0.973],P＜0.001) and 0.882 (95％ CI [0.807,0.956],P＜0.001) respectively.The sensitivity and specificity were 93.5 ％ and 100 ％ for differentiating normal and SS groups,83.3 ％ and 84.2 ％ for differentiating SS and NASH groups.Taking SWV≥3.48 m/s as cutoff to predict fibrosis (≥F2 stage),the AUC was 0.963 (95％CI [0.909,1.000],P＜0.001),the sensitivity was 92.9％ and the specificity was 97.6％.Taking SWV≥3.61 m/s as cutoff to predict severe fibrosis (≥F3 stage),the AUC was 0.997 (95％CI [0.990,1.000],P＜0.001),sensitivity was 100％ and specificity was 98.9％.The same high validity was maintained as in the prediction of cirrhosis (F4 stage) with the cutoff as SWV≥4.50 m/s,and the AUC was 0.993 (95％CI [0.982,1.000],P＜0.001),the sensitivity was 100 ％ and the specificity was 96.8％.Conclusion ARFI elastography is a promising method for differentiating the different severity of NAFLD and staging the degree of hepatic fibrosis with NAFLD in rat models.

OBJECTIVETo explore the minimally invasive treatment for fresh acromioclavicular dislocation and the distal clavicle fracture.

METHODSThirty skeletons of human shoulder were measured and compared, and the normal data on healthy people were measured with the help of ultrasound-guided. So the invasion point was located at the cross between subclavian axis and the line from coracoid tip to apophysis behind cone ligament node. From January 2001 to January 2010, 127 patients with fresh acromioclavicular dislocation and distal clavicle fracture were treated with minimally invasive internal fixation after locating the invasive point at the body surface. Among the patients, 97 patients were male and 30 patients were female, ranging in age from 19 to 56 years, with an average of 43 years. According to Rockwood classification, among 93 patients with fresh acromioclavicular dislocation, 67 patients were type III, 11 patients were type IV and 15 patients were type V. All the 34 patients with distal clavicle fractures were associated with coracoclavicular ligament broken. The duration from injury to operation ranged from 1 to 8 days. The therapeutic effects were evaluated by using the of shoulder scoring system, University of California (UCLA).

RESULTSAfter the minimally invasive treatment, all the patients had completely reduction at early time. One hundred and thirteen patients were followed up,and the duration ranged from 13 to 15 months,averaged 14 months. Nine patients had screw loose slightly within 30 days, but the reductions and functions were acceptable. Seven patients had complications of frozen shoulder and recovered in 6 months. The average UCLA shoulder score was (32.0 +/- 4.7), and 87 patients got an excellent result, 20 good and 6 fair.

CONCLUSIONThis minimally invasive treatment has advantages such as little trauma and low cost, which is worthy of clinical applications.

Objective:With Diagnosis related groups(DRG)indicator introduced into the hospital efficiency evaluation, to analyze the adjustment effect of DRG on the efficiency value, and to compare the similarities and differences between the DEA efficiency value and the DRG efficiency indicator.Methods:The DRG pilot data in 2017 and 2018 of tertiary hospitals in Hubei province and related data from other reports were collected. Indicators including the actual number of beds, the number of employees, the actual total bed days occupied, and medical income were used as input indicators, and total admissions, number of discharges, weight of DRG and number of DRG groups were used as output indicators. 7 models were constructed using different indicator combinations. The efficiency of the hospital was calculated by the Bootstrap-DEA efficiency evaluation method. The relationship between hospital attributes and efficiency was analyzed by a generalized linear model.Results:There was an abnormal phenomenon that the higher the hospital level, the lower the efficiency in the efficiency value calculated by the traditional method. The efficiency values of county hospitals, city hospitals and provincial hospitals were 0.83, 0.74 and 0.71, respectively( P<0.01). DRG weight and group number were used as output for DEA analysis, and the efficiency values of county hospitals, city hospitals, and provincial hospitals were 0.95, 0.95 and 0.96( P=0.20)respectively. The DRG efficiency indications of county hospitals, city hospitals and provincial hospitals were 1.42, 1.11, 1.00 respectively( P<0.01). The higher the level, the lower the efficiency, while the efficiency values calculated by DEA were 0.84, 0.82, 0.86, respectively( P=0.58). Conclusions:The efficiency value calculated by the traditional method presents a systematic bias, which could be corrected effectively when DEA analysis using DRG weights is used as output indicator. The results developed new ideas of efficiency analysis for hospitals practicing DRG management.

Objective:To quantitatively measure the level of hospital human resources management of public hospitals in China with D-CHMS.Methods:From January through December of 2019, the Development Chinese Hospital Management Survey(D-CHMS)was used in field survey of relevant personnel of 36 tertiary general hospitals and 27 secondary general hospitals, with 10 persons chosen from each hospital. Survey data were subject to descriptive analysis and t test, for quantitative measurement of the human resources management level of these sample hospitals. Results:The level of human resources management in Chinese public hospitals was on the low side, as seven secondary dimensions scored 2.94 in average. To name a few, talents retention and talents recruitment scored the lowest, being (2.13±0.29) and (2.90±0.63) respectively. Tertiary hospitals presented an obviously better performance than secondary hospitals in incentives for best performers, talents retention and recruitment. Human resources management level of hospitals in China′s west regions scored the highest, followed by those in the east regions.Conclusions:Public hospitals in China, especially secondary hospitals were expected to enhance their human resources management. Approaches recommended include building a talent pool, developing a series of preferential policies, building development platforms, optimizing performance appraisal, motivating remuneration schemes, and offering unique employee value propositions, which serve to recruit and retain talents.

Objective:To analyze the current situation of research on the moral culture construction of the healthcare industry in China, and provide reference for further promoting such construction.Methods:Relevant literature on the moral culture construction of the healthcare industry published from 2012 to April 18, 2022 were retrieved on CNKI, and bibliometric analysis was made on the temporal distribution, sources, institutional cooperation, keyword clustering, etc. of the literature through CiteSpace 5.8.R3 software.Results:A total of 126 effective documents were included, and the highest number of published articles was 23 in 2018. The top 5 journals were all non-core journals with a total of 45 articles(35.71%). The number of papers issued by 11 research institutions was 2, and the other 102 were all 1. The overall density of the knowledge map network of research institutions was 0. The top three keywords in terms of frequency were " moral culture construction" , " hospital" and " medical ethics" , of which the heart rate was>0.1.The results of cluster analysis of subject research showed that the research subjects of the moral culture construction of the healthcare industry mainly focus on the construction of hospital moral culture and medical ethics. Most of the research subjects focused on hospitals, and focus on the construction of public hospitals′ moral culture. The research content was related to medical ethics, party conduct, and doctor-patient relationship.Conclusions:Medical and health institutions should pay more attention to the construction and research of moral culture, expand the depth of research, enhance the influence of this research field, and pay attention to the construction of moral culture of healthcare institutions outside hospitals.
