This paper made systematic description of the three objectives of sustainable development designed for the policy based on the sustainability theory for the health sector.The essential drug system for secondary hospitals comprises the list coverage and allocation percentage of essential drugs,requirements for bidding and purchasing as well as pricing practice; management and conditions of these hospitals,including leadership determination and competency,doctors prescription behavior,and supportive reforms at these hospitals; external policies and social environment,including government financial subsidy,medical service prices adjustment,medical insurance,and the awareness and attitude of the people on essential drugs.

Within the KABP model as a framework,the authors studied these behaviors at the following three levels,namely knowledge and learning,beliefs and attitude,and behavior.Such aspects as the education background and training,drug expertise,drug infonmation sources,personal experience and habits,attitudes,needs of physicians and patients',socio-demographic characteristics were discussed among others to probe into how physicians' personal behavior affects their prescription behavior.Recommendations raised include education and training,provision of correct drug information,greater publicity,better compensation mechanism of public hospitals,strengthened supervision,establishment of the system of prescription audit,etc.

BACKGROUND: Traditional anterior release followed by posterior correction and fusion is frequently used to treat severe and rigid adolescent idiopathic scoliosis, which is considered as Cobb angle of the major curve > 65° and flexibility < 34.5%; however, there are a great majority of complications. Whether isolated posterior correction using pedicle screw fixation combining with bone grafting and fusion may provide better effects on severe and rigid adolescent idiopathic scoliosis needs to be further studied.OBJECTIVE: To evaluate isolated posterior correction using pedicle screw fixation combining with bone grafting and fusion for the treatment of severe and rigid adolescent idiopathic scoliosis. DESIGN: Case analysis.SETTING: Department of Orthopaedics, Renji Hospital, Medical College of Shanghai Jiao Tong University.PARTICIPANTS: Twenty patients with severe and rigid adolescent idiopathic scoliosis, including 8 males and 12 females, were selected from Department of Orthopaedics, Renji Hospital, Medical College of Shanghai Jiaotong University from June 1999 to August 2005. They were 12-18 years old, and the mean age was 14.6 years. All patients were finally diagnosed as X-ray of whole spine. According to King-Moe criteria, patients were classified into type Ⅰ(n =4), type Ⅱ(n =6), type Ⅲ (n =5), type Ⅳ(n =3) and type Ⅴ(n =2). Before surgery, mean Cobb angle of the major curve was 82° (75°-92°), mean flexibility was 30% (20%-40%), and mean shoulder height difference was 15 mm (5-35 mm). Moreover, according to Risser syndrome, patients were classified into degree 1 (n =3), degree 2 (n =5), degree 3 (n =6), degree 4 (n =5) and degree 5 (n =1). All patients and their relatives provided the informed consents, and the experiment was approved by the local ethical committee. Artificial bone was Osteoset provided by Wright Company, USA.METHODS: Patients underwent isolated posterior correction using pedicle screw fixation combining with bone grafting and fusion, and spinous process, lamina of vertebra, zygapophysial joints and transverse process were exposed in a preconcerted fusion area. Pedicle screw was inserted into strategy vertebra using free hand technique according to the anatomic landmark of entry point. Six patients underwent fixation with TSRH system, and the other patients with CDH M8 system. Operative time and blood loss were evaluated after surgery. At 7 days after operation, Cobb angle was measured with X-ray, and correction rate of major curve was calculated. While shoulder height difference and admission duration were evaluated simultaneously. Complications and recovery states were followed up in the next 4 years.MAIN OUTCOME MEASURES: ① Operative time and blood loss; ② Cobb angle and correction rate of major curve; ③ shoulder height difference and admission duration; ④ follow-up results.RESULTS: All 20 patients were included in the final analysis. ① Operative time and blood loss: Operative time lasted from 3.2 to 4.3 hours, and the mean time was 3.5 hours. Blood loss ranged from 660 to 1 070 mL, and the mean loss was 865 mL. ② Cobb angle and correction rate of major curve: Cobb angle of the major curve ranged from 82° (75°-92°) before surgery to 31° (22°-37°) after surgery, and the mean correction rate was 62%. ③ Shoulder height difference and admission duration: Mean should height difference before surgery was 15 mm (5-35 mm). Postoperative lateral film of spine indicated that thoracic and lumbar vertebra generally suffered from normal posterior and anterior convexity, and mean shoulder height difference after surgery was 7.5 mm (0-11 mm). The admission duration lasted from 8 to 11 days, and the mean duration was 9 days. ④ Follow-up results: All patients were followed up in the next 4 years after surgery. The cobb angle correction of major curve remained unchanged, and the instrumented segments were completely fused without instrumentation failure.CONCLUSION: Isolated posterior correction using pedicle screw fixation combining with bone grafting and fusion may effectively cure severe and rigid adolescent idiopathic scoliosis, which is considered as Cobb angle of the major curve between 75° and 92° and flexibility ≥ 20%.

A field survey of three counties in a province in west China analyzed the public health performance from the dimensions of input, output and outcomes, and computed the composite evaluation indexes for public health performance of the sample areas. The indexes so obtained are as follows: Low public health input in general; gap of public health outcomes among various public health programs;generally high outcome performances. The paper proposed to improve the fund raising mechanism for rural public health, build a performance-based investment mechanism, balanced provision of primary public health services, and secure supports from all the society, in an effort to promote public health development in rural areas.

Objective To give an empirical study on the interests claims of employees in public hospitals. Methods By questionnaire investigation, to sum up data using factor analysis and pairedsamples T test, and to compare difference between different kinds of patients using ANOVA. Results The interests claims of employees can be summed up to seven factors and there is some significant difference between different kinds of employees. Conclusion At current stage, public hospitals need pay more attention to material interests claims of employees.

An analysis of the fundamental concepts for public hospital reform further defined public hospitals and other hospitals,business and non-business in nature,public benefits and welfare,as well as public benefits and profit-oriented hospitals.These distinctions can help reformers of public hospitals clarify their concepts,make clear the purpose and direction of the public hospitals reform,so as to speed up the reform with theory support.

This paper studied the development stages in terms of the public nature of public hospitals in China and analyzed the causes for their weakened public benefits.It proposed the principle of government guidance,achieving government purchasing of healthcare services as the roadmap,as well as building and improving the service purchasing system,performance appraisal system,and payment review system along with supervision system.These measures are designed to make public hospitals in their public benefit nature with scientific system design,powerful institutional guarantee,and efficient execution strategies.

Objective To provide reference for improving the performance of public health by establishing performance evaluation framework of public health in rural areas of China.Methods The performance evaluation framework of public health in rural areas is established by literature research,theoretical derivation and Delphi method.The results of expert consultation are tested by W test of Kendall coordination coefficient and chi-square test.Results The performance evaluation framework of public health in rural areas contains four conceptual modules,ten performance goals and twenty-eight performance evaluation indexes.The positive coefficient of experts is 0.889.The average values of authoritative grade of experts are between 0.681～0.715.The Kendall W uniformity coefficients of the necessity,sensitivity and maneuverability of the indexes are respectively 0.167,0.209 and 0.185.The P values are less than 0.01.Conclusion The performance evaluation framework of public health in rural areas has certain application value.It is necessary to pay attention to scientific nature and applicability in developing performance evaluation of public health in rural areas.

Objective To provide reference for focusing and improving policy efficiency in China by establishing the conceptual model and index system of effectiveness of Township and Village Health Services Integration Policy(TVI).Methods The conceptual model and index system of TVI effectiveness were established by literature review and Delphi method.Comprehensive Index Method and Weighted TOPSIS Method were used in index consistency check.Results The conceptual model and index system of TVI effectiveness contain four conceptual modules,8 policy goals and 27 evaluation indexes.The positive coefficient of experts is 0.95 and authoritative grades of experts are more than 0.90.Conclusion Based on SPO Model,the conceptual model and index system of TVI effectiveness in China have been established,which consists three aspects:construction of organization system,health services and satisfaction.

Object Through performing the service satisfaction survey,to learn their interest claim and discover the service defects ,so as to provide advice and countermeasures.Method Using field survey methods and statistics analysis to study.Result The satisfaction of relatives of pediatric patients at the level of "relatively good" and "good" is about 60% both in medical treatment environment and equipment ,over 70% in medical treatment effect,doctor capacity,nursing capacity and overall assessment,but only 5.1% in medical expenses.Conclusion Relatives of pediatric patients have high satisfaction in treatment capability of medical staff,medical treatment effect as well as overall assessment ,normal satisfaction in medical environment and equipment,but lowest satisfaction in medical expenses,and the satisfaction in tertiary hospital is not high.Relatives in some districts demand much in some aspects,such as improving hospital environment,attaching importance to ward hygiene ,improving service attitude,and providing single ward ect.
