Objective To identify the determinants of average length of stay of 16 upper first-class general hospitals from 2000 to 2007.Methods Relative data of 16 upper first-class general hospitals from 2000 to 2007 were collected, and descriptive analysis and multiple linear regression analysis were employed to explore the determinants of average length of stay. Results Operation ratio and days before operation of inpatients, ratio of salary to medical income, ratio of doctors to nurses, successful rescue rate in emergency, number of operation tables and staff had impact on average length of stay. Conclusion Resource allocation should be optimized, health care quality be enhanced, reasonable salary scheme be designed, and rational medical insurance policies be implemented in hospitals to shorten average length of stay.

Objective To comprehensively evaluate the competitiveness of hospitals so as to provide objective referrences for the long-term development. Methods Competitiveness evaluation index system and evaluation model were established. Using related data of 2007, 16 hospitals nationwide were evaluated and factor scores and comprehensive scores were obtained by means of factor analysis. Results Four factors were extracted, which were "technical efficiency factor", "economic income factor", "sustainable development factor" and "resource allocation factor". All hospitals were ranked by each factor score and comprehensive score. Conclusion Each hospital has its advantages and disadvantages, therefore, hospital managers should constitute individual development strategy accordingly.

Performance appraisal is an important means for keeping hospitals on correct tracks for their medical services and their public interest nature,in addition to its importance in enhancing internal performance management within public hospitals.Since 2006,Shanghai Shenkang Hospital Development conducted performance appraisal for directors of 23 public hospitals in Shanghai.This paper highlights the importance of performance appraisal for these directors,and its significance in keeping the correct director of hospital operation.

Objective To learn the present hospital management conditions in Shanghai for upgrading quality of care.Methods The stratified sampling method was used for a questionnaire survey of the quality of care at 20 hospitals in Shanghai (10 tertiary hospitals and 10 secondary hospitals).The survey covered such six dimensions as organizational framework,management functions,management tools,professional training,regulations and norms,and supervision over operations.Results Medical quality management system is established at such hospitals and all of them have established medical quality management committees.Rooms of improvement remain in such details as departmental quality management,regulations standardization,IT support,and management tools popularity.Conclusion Management regulations and standards of medical quality management should be improved and implemented from both external and internal aspects,to improve medical quality and patient safety.

Purpose/Significance To elucidate the complex relationship among face phenotype-disease-gene,and to explore the underlying mechanisms of their interactions.Method/Process Based on scientific literature from the PubMed database,natural language processing tools and manual filtering methods are used to extract the knowledge of the concept and relationship of face phenotype-disease-gene reported in the existing literature,and a knowledge base is constructed.Result/Conclusion The study completes the framework design and construction of the knowledge base of the face phenotype-disease-genotype for intelligent health application,which lays a foundation of both data and theory for exploring the interplay between face phenotype-disease-gene,as well as the potential application of face phenotype in disease diagnosis.
