With building up a clinical modification system model by upgrading the standard disease classification system architecture,to collect those huge amount of diagnosis names and codes in use,based on the model to screen and coordinate the relation of them,the tenth revision of the International Classification of Disease Clinical Modification of Beijing is implemented.This standard has been successfully applied for two years in all those secondary and above level hospitals in Beijing.It could well support the work of deploying Diagnosis Related Groups in Beijing and support not only those traditional applications of disease classification but also those new and advance requirements of information processing.

Objective Taking the respiratory department of internal medicine as an example, to compare the coverage of clinical treatment of the MDC covered by DRGs of Beijing version with the professional services offered as secondary clinical treatment subjects in China.Methods Using the data from medical record home page from hospitals in Beijing above secondary level from 2012 to 2014 and both the DRGs defined in Pareto diagram statistical method and the DRGs proved by experts, for analysis and definition of the DRGs coverage involved by respiratory discipline of internal medicine.Results Respiratory discipline of internal medicine involved DRGs of 42 groups as found by the two methods.Conclusion The DRGs scope of secondary clinical departments in hospitals should be made based on both expert consultation and clinical data statistics method.

Collection and quality control of inpatient medical record home page information are key to the study and use of DRGs.The paper covered the sampling methods, inspection items, inspection methods, data assembly methods, and data reporting quality scoring methods of Beijing authorities on the hospitals in the city.Also introduced were the inspection results of the city in 2014, which prove a satisfactory outcome in the end.

Objective To analyze the applicability of case mix index (CMI) in medical performance evaluation of different type of hospitals and its calculation method.Methods Standardized adjustment to the CMI value of hospitals according to the CMI of the main disease categories (MDC) of short-term inpatient cases of the city, to align the CMI values of various hospitals with their levels of medical and technical services.Results The said adjustment ensures the CMI value to better represent the levels of such hospitals.Conclusion The adjusted CMI calculation method can provide accurate data support for various hospitals' performance evaluation.

Objective To analyze the inpatient specialist capacity of a hospital during 2013-2014 in Beijing for its specialists development, based on relevant local specialist development.Methods Analyzing the inpatient specialist capacity using case mix index (CMI) and DRG numbers according to BJ-DRG grouping method.Each MDC of the hospital is divided into four types according to the status and development of inpatient specialist capacity.Results Of the 19 MDCs, 2 (such as nervous system disease) fall into type 1, 6 MDCs (such as neck, ears, nose, mouth, pharynx disease and dysfunction) into type 2, while 5 MDCs (such as female reproductive system diseases and dysfunction) into type 3, and 6 MDCs (such as pregnancy, childbirth and postpartum) into type 4.Condusion Most of the MDC inpatient specialist capacities of the hospital in question are at ranking high in Beijing, and such capacities for various MDC can be improved by all means.

Objective To use diagnosis related group (DRGs ) for the first time in overall evaluation of inpatient service performance evaluation of major diagnostic category (MDC)for all the Beijing municipal hospitals,and recommend how to strengthen Beijing municipal hospitals system in diagnosis and treatment ability of main diseases and improve inpateint service performance.Methods BJ-DRGs burster software was used to analyze the first page information of the medical records of cases discharged from all the Beijing municipal hospitals between 2012 and 2014 to determine the weight of each DRG,and based on such weight the related indicators of such hospitals and central hospitals in 2012, 2013,2014 were compared and analyzed.Results Improvements were found in such indices as diagnosis and treatment difficulty of 50% MDC,time efficiency of 81.8% MDC,cost efficiency of 77.3% MDC, and general capacity of 54.5% MDC for all Beijing municipal hospitals.In addition,the municipal hospitals were found superior to the central hospitals in such indices as cost efficiency of 68.2% MDC, and time efficiency of 59.1% MDC.On the other hand however,they were found inferior to the central hospitals in such indices as diagnosis and treatment difficulty of 72.7% MDC,and the comprehensive ability index of the two systems were found equivalent.Another finding was that there was no obvious improvement of the coverage of disease types at major tertiary hospitals in Beijing for the past three years.Municipal hospitals of greater contribution of MDC weight were highly consistent with the hospitals assigned with national key projects of disciplinary developments. Conclusion The comprehensive evaluation results of inpatient service performance of main diseases at Beijing’s municipal hospitals based on DRGs system,showed that the Beijing’s hospital authority had played an important role in improving inpatient service performance especially in reducing the burden of patients,improving the service efficiency through increasing government investment,optimizing service organization and implementation of performance management.But it also suggested that measures such as collectivize construction and management should be taken to improve municipal hospitals’linical specialty ability, improve the MDC diagnosis and treatment difficulty,and resume their functions of tertiary hospitals.

OBJECTIVETo observe the changes of hospitalization rates and in-hospital mortality for coronary heart disease (CHD) in Beijing from 2007-2012.

METHODSPatients hospitalized for CHD in Beijing from 1 January 2007 to 31 December 2012 were identified from"The Cardiovascular Disease Surveillance System in Beijing". In total, 421 929 patients aged ≥25 years of permanent Beijing residents were admitted for CHD in Beijing during the 6 years. After excluding duplicate records and validation for the completeness and accuracy of the records, the hospitalization rates for CHD and in-hospital CHD mortality were analyzed. Trends in hospitalization rates and the in-hospital mortality for CHD were analyzed with Poisson regression models.

RESULTSThe age-standardized average hospitalization rate of CHD was 515.3 per 100 000 population in patients aged ≥25 years in Beijing. During the six years, an increasing trend was observed in the hospitalization rates for CHD after adjusting the age and gender (P<0.001). The age-standardized hospitalization rates of CHD increased by 43.0% in the past six years. The greatest increases of hospitalization rates were noted in both men and women between 45 to 54 years. The age-standardized in-hospital mortality decreased from 3.3% to 2.2% over the time (P<0.001), with a in-hospital mortality reduction for acute myocardial infarction from 11.3% to 8.5%.

CONCLUSIONSAn increasing trend in hospitalization rate was observed during 2007-2012 for Beijing residents aged ≥25 years, indicating an urgent need in CHD prevention in Beijing. The in-hospital mortality reduction during this period might reflect the improvement in the in-hospital treatment modalities of CHD.

Objective:To study the relationship between the absorptive capacity of inpatients with infectious diseases and the structure of diseases in 65 secondary and tertiary general hospitals in Beijing,and to objectively analyze the current situation of space utilization of inpatients with infectious diseases,so as to provide data support for the formulation of relevant policies.Methods:The variability of spatial absorption capacity indicators for secondary and tertiary general hospitals in 6 urban districts and 10 suburbs were compared separately,and the correlation between the spatial absorption capacity of secondary and tertiary general hospitals and the structure of disease types was visualized and analyzed using quadrant bubble charts.Results:In terms of spatial absorption capacity,there was a statistically significant difference in the proportion of patients from suburban districts treated in the secondary and tertiary general hospitals in 6 urban districts of the Beijing(P=0.003),while there was no statistically significant difference in the proportion of patients from other districts treated in the secondary and tertiary general hospitals in 10 suburbs(P=0.336).The spatial absorption capacity and disease structure of the secondary and tertiary hospitals in 6 urban districts and the tertiary hospitals in 10 suburbs showed significant correlation,while the secondary hospitals in 10 suburbs showed no significant correlation.Conclusion:The tertiary general hospitals in 6 urban districts have superior infectious disease type structure indicators,with significantly stronger spatial absorption capacity and stronger correlation between these two,which plays the function of inpatient service of difficult and severe infectious diseases.Only the district hospitals in the outer suburbs can provide inpatient services for infectious diseases,and the number of cases admitted is large,which meets the needs of inpatient diagnosis and treatment of common infectious diseases in the district.It is necessary to strengthen the investment of infectious disease medical resources and capacity building in 10 suburban districts according to the actual situation.

Objective:The service capacity of infectious diseases department in Beijing secondary and tertiary general hospitals was quantitatively analyzed to provide objective data support for the construction of infectious diseases department.Methods:The scope of infectious diseases was defined by the DRG tool,and the service capacity of medical institutions was described by the Case Mix Index(CMI)and number of DRG groups.The differences in the service capacity of infectious diseases in 67 secondary and tertiary general hospitals in Beijing from 2016 to 2020 were analyzed by data visualization and generalized linear equation,and the disease structure of different hospitals at different levels was compared by selecting representative hospitals.Results:From 2016 to 2020,the mean CMI of tertiary hospitals ranged from 0.94 to 0.97,while that of secondary hospitals ranged from 0.70 to 0.72.From 2016 to 2019,the average number of DRG groups in tertiary hospitals ranged from 26.75 to 27.79,and the average number of DRG groups in secondary hospitals ranged from 15.32 to 15.77,and the average number of DRG groups in secondary and tertiary hospitals showed a significant decline in 2020.CMI and number of DRG groups had statistical significant difference at hospital level(P＜0.001),and number of DRG groups had statistical difference in time dimension(P＜0.001).Conclusion:The infectious disease service capacity of tertiary general hospitals is obviously stronger than that of secondary general hospitals,and the infectious disease medical service capacity of large tertiary hospitals is obviously ahead,while the overall service level of secondary hospitals is low.We should give full play to the advantages of top three hospitals to build a high ground for infectious disease department construction,and combine the spatial distribution of medical resources and demand characteristics to improve the infectious disease service capacity of secondary hospitals.
