职业流行病学研究是以观察法为主要手段,研究的对象是具有某些特征的职业人群。同一般实验性研究相比,流行病学研究过程更容易受到各种外界因素的干扰,造成研究结果偏离于真实情形,从而使研究的质量降低。在研究过程中控制质量,不仅是流行病学研究成败的前提,也是做好职业病防治工作的保证。一、质量控制标准在职业流行病学研究过程中,控制质量的标准是
The occupational epidemiology study is based on the observation method as the main method, and the research object is the occupational group with certain characteristics. Compared with the general experimental research, the epidemiological research process is more susceptible to interference from various external factors, resulting in the deviation of the research results from the real situation, thus reducing the quality of the research. Controlling quality during the research process is not only a prerequisite for the success or failure of epidemiological research, but also a guarantee for the prevention and treatment of occupational diseases. I. Quality Control Standards In the process of occupational epidemiology, the criteria for controlling quality are
