目的:了解铁路职工的艾滋病知识、态度和行为(KAP)的基本情况,为开展健康教育及干预措施提供依据。方法:采用整群抽样方法对530名铁路职工进行自填式问卷调查。结果:有效问卷502份。对艾滋病传播途径的认知率达到80%以上,但对艾滋病的非传播途径认知水平较低。对艾滋病治疗方面的知识较为欠缺(认知率在22.31%～57.77%)。对于安全性行为的正确认知率为48.01%,正确使用安全套的认知率为69.92%。对艾滋病感染者或患者的态度正向选择率为58.16%。不同文化程度对艾滋病态度的差异有显著性(Plt;0.01)。 结论:铁路职工艾滋病相关防治知识认知水平较低,应加强艾滋病知识、态度和行为的相关健康教育。
【摘要】 目的 探讨健康教育路径在下腔静脉滤器（inferior vena cava filter，VCF）置入术患者中的应用效果。 方法 2008年1月－2010年5月，将62例VCF置入术患者随机分为观察组（32例）和对照组（30例），观察组采用健康教育路径进行健康教育，对照组患者采用常规健康教育。 结果 观察组患者的健康教育达标率明显高于对照组（Plt;0.05），焦虑发生率明显低于对照组。 结论 应用健康教育路径对VCF置入术患者实施，能提高患者对健康知识的掌握程度和效果，促进患者早日康复；同时可强化护患沟通，和谐护患关系。【Abstract】 Objective To investigate the effect of health education pathway in patients treated with placement of inferior vena cava filter (VCF). Methods Sixty-two patients treated with placement of inferior VCF from January 2008 to May 2010 were randomly divided into experimental group (n=32) and control group (n=30). Health education pathway and routine general way were adopted respectively to treat patients in the experimental group and the control group. Results Standard-achieving rate of the health education in the experimental group was significantly higher than that in the control group (Plt;0.05), and the incidence of anxiety was also lower in the experimental group. Conclusion Health education pathway for patients treated with placement of inferior VCF can increase the patients’ health care knowledge, lessen patients’ anxiety, and strengthen the nurse-patient communication and harmonious relations.
The correlation coefficient is a common used statistic index in the management science, sociology, psychology and nursing. The meta-analysis based on data of correlation coefficients has increased nowadays. The meta package and metafor package are the two major packages in R for performing meta-analysis and can implement many types of meta-analysis, including the meta-analysis of correlation coefficients. This article gives a brief introduction of the process to perform meta-analysis of correlation coefficients using these two packages, and compares their statistical results and functions (such as plot drawing).
The metacor, which is developed based on the classical frequentist theory, is a specified package for performing meta-analysis of correlation coefficients in R software. This package was officially launched in 2011. Based on the DerSimonian-Laird method and Olkin-Pratt method, correlation coefficients can be directly pooled by using this package. The metacor package also can be used to draw the forest plot and is easy to use; however, it still needs to be improved. This paper briefly introduced how to perform a meta-analysis of correlation coefficients using the metacor package in R software through an example.
