卫生统计可分为经常性统计和一时性统计两种。经常性统计资料主要从日常医疗卫生工作原始记录(如病历)专门报告卡(如出生卡、死亡报告卡)、统计报表(如疫情日报表、年报表)中搜集。一时性统计资料常指现场调查和实验室研究收集。医务工作者可运用统计分析方法,结合专业知识,从经过整理的资料中,计算需要的指标,进行统计描述与统计推断,阐明事物发展的规律。 Health statistics can be divided into two kinds of regular statistics and temporary statistics. Recurrent statistics are mainly collected from the original record of daily medical and health work (such as medical records), special report cards (such as birth card and death report card) and statistical reports (such as epidemic situation reports and annual reports). Temporal statistics are often collected on site and in laboratory studies. Medical workers can use statistical analysis methods, combined with professional knowledge, from the collated information to calculate the required indicators, statistical description and statistical inference, to clarify the law of the development of things.
