This study describes the incidence of neonatal abstinence syndrome (NAS) in Ontario, Canada by year and health region from 2003 to 2016.
The incidence of NAS diagnoses per 1,000 live births was calculated for the 36 local public health agency regions in Ontario from 2003 to 2016 using retrospective hospital admissions data. Infants with a diagnosis of NAS were identified using ICD-10 code P961. Local public health agency level data were aggregated and analyzed by geographic region and by Statistics Canada 2015 Peer Groups.
The incidence of NAS in Ontario increased from 0.99 per 1,000 live births in 2003 to 5.94 per 1,000 live births in 2016. There were major differences in NAS incidence by geography, North Western Ontario had the greatest incidence across all years. Health regions with a rural and population center mix or mostly rural population had greater incidence rate of NAS compared to health regions with high density population centers.
The incidence of NAS has dramatically increased across Ontario in the last decade. Actions should be taken to combat the continued increase in NAS rates, especially in health regions with disproportionately high incidence of NAS.
本研究描述了2003年至2016年加拿大安大略省新生儿戒断综合征（NAS）按年份和卫生区域划分的发病率。
利用回顾性医院入院数据，计算了2003年至2016年安大略省36个地方公共卫生机构区域每1000例活产中NAS诊断的发病率。使用国际疾病分类第10版代码P961识别诊断为NAS的婴儿。地方公共卫生机构层面的数据按地理区域和加拿大统计局2015年同类组进行汇总和分析。
安大略省NAS的发病率从2003年每1000例活产中的0.99例增加到2016年的每1000例活产中的5.94例。NAS发病率在地理上存在重大差异，安大略省西北部在所有年份中的发病率最高。与拥有高密度人口中心的卫生区域相比，兼具农村和人口中心或主要为农村人口的卫生区域NAS发病率更高。
在过去十年中，安大略省NAS的发病率急剧上升。应采取行动应对NAS发病率的持续上升，特别是在NAS发病率过高的卫生区域。
