Objective To research the effects of establishing core system key risk index in reducing adverse events. Methods Analyzed the causes of the 147 adverse events in 2014. Including the core system implementation of the reasons for the end of the adverse events caused, the data of fundamental reasons in adverse events and the high risk link that because nurses don′t practice the core system. In 2015, randomly checked the 29 nursing units, including 27 wards and emergency outpatient transfusion room, ICU. Contains the implement rates of the core system in transfusion treatment, day and night shifts, doctors′ advice and patients′ identification. In order to quarterly analysis the index and pertinently improve the results, assessors of quality administration council, head nurse in endemic area and attendant watch keeper are chosen to gather index data. Results After one year of management, the key aspects of the core system execution qualified rate has reached 95%, the check of the implementation of the system, the total pass rate compared with before had increased 6.94%, orders execution system implementation of a qualified rate had increased 9.33%, patient identification system implementation of qualified rate had increased 4.29%, the qualified rate of change of comparison the differences were statistically significant (P<0.05). After the establishment of the core system key risk index management, the adverse events had decreased 11.06%(P < 0.05). Conclusion The establishment of the core system key risk index management can effectively improve the implement rates and reduce the nurse adverse events.

OBJECTIVETo analyze the status of maternal health behaviors and it's risk factors for Yi-nationality women in poor rural areas of Sichuan province.
METHODSIn 2012, multi-stage stratified cluster sampling method was used to select 14 villages of two poor counties in Liangshan Yi-nationality autonomous prefecture Sichuan province. At least 10 women who have infants aged 0-12 months were selected in each simple villages, a total of 284. The structured questionnaire was developed on the basis of the theory of reasoned action. Yi-nationality female college students were trained as investigators. Research indicators included prenatal care rate, hospital delivery rate, postpartum examination rate, socio-demographic characteristics, maternal health care knowledge. χ² test was used to compare the differences of above indicators among different groups. The structural equation model were used to statistical analyze.
RESULTSIn the 284 subject women, 51.7% (147/284) women owned more than 2 children, 41.6% (118/284) women were more than 30 years old, 87.3% (248/284) women were illiteracy. The prenatal care rate was 69.7% (197/284), the hospital delivery rate was 26.8% (76/284), and the postnatal check rate was 22.9% (65/284). The influence factors of maternal health behaviors included the number of children, age and education (χ² were 10.92, 13.24, 9.58; P values were 0.027, 0.004, 0.008, respectively).The structural equation model analysis results showed that the maternal health behaviors were directly or indirectly affected by subjective norms (β = 0.236, P < 0.001), women's cognition (β = 0.226, P = 0.020) and women's attitudes on maternal health behavior (β = 0.157, P = 0.001). Among subjective norms, women have high compliance to their husbands (β = 0.850, P < 0.001), their peers (β = 0.708, P < 0.001), and their mothers-in-law (β = 0.636, P < 0.001).
CONCLUSIONThere were still serious problems in maternal health behaviors for Yi-nationality women in poor rural areas. The main factors included not only the women's cognition and attitudes for maternal health, but also the attitudes of important social relationships.

5.Research in physical exercise among rural adolescents based on the theory of planned behavior in Sichuan Province
Chinese Journal of School Health 2021;42(1):41-45
Objective:
To verify the applicability of the theory of planned behavior(TPB) in the physical exercise behaviors of rural adolescents in Sichuan Province, and to explore the possible influencing factors of physical exercise behaviors, and to provide a theoretical basis for further effective intervention measures.
Methods:
A total of 2 302 students were selected from grade seven and grade ten of two rural middle schools in Zizhong, Sichuan Province. The survey was conducted with a structured questionnaire. Using TPB as the research framework and basis, the structural equation model was constructed for analysis.
Results:
Lack of physical exercise was 1 527(66.3%).Physical exercise behavior was statistically different among schools, grades(t=-7.40,-2.90,10.90,P<0.05), and genders. Based on TPB, the structural equation model was established and corrected to obtain the revised model, and the fitting index GFI=0.93, CFI=0.94, NFI=0.94, TLI=0.93, IFI=0.94,RMSEA=0.07, indicating the model fitted good. Exercise intention directly affected exercise behaviors. The standardized effect was 0.45(95%CI=0.39-0.52). Subjective norms and perceived power were the main two mediators of the relationship between value evaluation and exercise intention. The standardized effect values were 0.66(95%CI=0.57-0.73), 0.23(95%CI=0.16-0.93)(P<0.01).
Conclusion
There is serious lack of physical exercise in rural adolescents in Sichuan Province. TPB has a good applicability for physical exercise in rural adolescents in Sichuan Province. Subjective norm is the most important factors to promote exercise intentions.
