Tennessee Birth Defects Data Report 2016-2020

This annual report provides details on the prevalence of 46 major birth defects for Tennessee infants born in the years 2016-2020. The primary data sources for this report are the Hospital Discharge Data System (HDDS) and the Birth, Death, and Fetal Death Statistical Data Systems. The methodology of data collection used for this report results in a time lag for analysis, since finalization of the HDDS files occurs one year after the birth year.

本年度报告详尽阐述了2016至2020年间田纳西州新生儿所患46种主要出生缺陷的普遍情况。本报告的主要数据来源为医院出院数据系统（HDDS）以及出生、死亡和胎儿死亡统计数据系统。由于医院出院数据系统（HDDS）文件的最终确定需在出生年份之后一年进行，因此本报告所采用的数据收集方法导致分析存在一定的时间滞后。
