Chinese version of the clinical learning environment comparison survey: Assessment of reliability and validity.

BACKGROUND: Simulation is recommended as a substitute for clinical practice among nursing students. No current guidelines exist regarding the accurate percentage of simulation hours versus clinical practice hours. Comparing simulation with clinical practice is needed so that both strategies can be optimally combined in nursing education. The 29-item Clinical Learning Environment Comparison Survey (CLECS) is validated to compare the traditional and simulated clinical environment in meeting nursing students' learning needs. This type of tool is not available in China. OBJECTIVES: This study aimed to translate and test the psychometric properties of CLECS for Chinese undergraduate nursing students. DESIGN: This is a cross-sectional study. SETTINGS: Two nursing schools in Central and East China. PARTICIPANTS: A total of 179 undergraduate nursing students who had participated in both traditional and high fidelity simulated clinical practice were recruited. METHODS: A standard procedure with forward translation, back translation, cultural adaptation and pilot testing was followed to test the CLECS (Chinese version). An exploratory factor analysis was used to establish a modified factor structure of CLECS (Chinese version); a confirmatory factor analysis verified its construct validity. Reliability of the CLECS (Chinese version) was estimated using the intraclass correlation coefficients (ICCs) and Cronbach's alpha coefficients. RESULTS: The exploratory factor analyses explained 61.43% and 60.11% of the total variances in traditional and simulated clinical environment. The proposed factor solution of the CLECS (Chinese version) obtained satisfactory model fit and nesting model between two nursing schools. In the proposed model, ICCs were 0.61 and 0.93, and Cronbach's alpha coefficients were 0.75 and 0.95 in the traditional and simulated clinical environment. CONCLUSIONS: The CLECS (Chinese version) showed satisfactory reliability and validity among Chinese undergraduate nursing students. Further validation of the CLECS (Chinese version) is needed in a more representative and larger sample. The CLECS (Chinese version) should be further tested as an effective tool to compare the traditional and simulated clinical practice among Chinese nursing schools.

[Risk assessment of schistosomiasis transmission on rescue workers involved in "Oriental Star shipwreck event"].

OBJECTIVE: To assess the impact of the "Oriental Star shipwreck event" on the risk of schistosomiasis transmission in Jianli County, Hubei Province, so as to provide the evidence for formulating appropriate measures of schistosomiasis prevention and control. METHODS: Based on the field observation and investigation, the data of the on-the-spot rescue and the historical endemic situation of schistosomiasis in Jianli County were collected and analyzed. Meanwhile, the focus group discussion and risk matrix were conducted to assess the risk of schistosome infection of the rescuers. RESULTS: Over 10 000 rescuers participated in the search operation, including the armed police forces, local people, reservists and so on. The armed police forces were the major components, which accounted for 39%. Jianli country was schistosomiasis endemic area with a high infection level in history, but the endemic situation had been mitigated significantly after years of positive prevention and treatment; the schistosome infection rate of population was 0.44% in 2014 and the Oncomelania hupensis snail area was only 6.6 hm2 around the rescue areas in the upstream and downstream. In addition, the snail density was not high, and no infected snails had been found for 11 years. The risk of schistosome infection was in the medium level. CONCLUSIONS: Though there exists the schistosome infection risk in the water area where the accident happened, the probability of occurrence is not high. In order to prevent the outbreak and endemic of schistosomiasis, the protection measures and health education to the rescuers as well as snail control and monitoring, and early-warning should be strengthened.

[Performance of detection and treatment in schistosomiasis in Hubei Province, 2011].

OBJECTIVE: To evaluate the performance of schistosomiasis detection and treatment program in Hubei Province in 2011, so as to enhance the benefit and management of the program. METHODS: In 63 schistosomiasis epidemic counties of Hubei Province, there were 3 types of endemic situation, that was endemic controlled, transmission controlled, and transmission interrupted. Six counties (districts) in each type were selected by the stratified random sampling method. The data including schistosomiasis detection and treatment, fund utilization and others were collected and analyzed statistically in 2011. RESULTS: The completion rate of schistosomiasis detection task was 103.9% and the completion rate of chemotherapy task 106.9%. The total fund was 73.815 million Yuan. The detection cost accounted for 12.0% while the chemotherapy cost accounted for 4.9%. The detection cost per capita was 9.03 Yuan and the treatment cost per capita was 10.35 Yuan. The cost effectiveness ratio was 1:6.1 and the net cost effectiveness ratio was 1:5.1. CONCLUSION: The social-economic benefits in schistosomiasis control and treatment are obvious. However, the resource allocation still needs to be optimized.

[Performance evaluation of small snail control projects in Hubei Province in 2009 and 2010].

OBJECTIVE: To evaluate the performance of small Oncomelania snail control projects in Hubei Province in 2009 and 2010, so as to explore the best snail control project in different areas. METHODS: The expense-effect, expense-efficiency and cost-utility analyses were carried out to analyze the small snail control projects with reference to the relevant schistosomiasis japonica prevention and control index system. RESULTS: The coverage rate of snail control was 40.15%, the decrease rate of the snail areas was 32.86%, the unit cost for the snail control was 0.39 Yuan/m2, the cost of reducing 1% of the snail area was 67.34 ten thousand Yuan, the total benefit was 15 554.14 ten thousand Yuan, the ratio of cost to benefit was 7.03, the net benefit was 13 341.44 ten thousand Yuan, and the ratio of cost to net benefit was 6.03, and the investment ratio was 1 : 2.11 in the 183 small snail control projects. CONCLUSION: There is an obvious and respectable short-period effect of the small snail control projects.
