Discharge Abstract Database, 2013-2014 [Canada]: Clinical Detail File

The Discharge Abstract Database captures administrative, clinical, and demographic information on hospital discharges. Two files are available: Clinical Detail and Geographic Detail. These files contain a 10% sampling of persons from the database. Reference dates were randomly assigned to selected individuals. The Clinical Detail File includes inpatient data from all acute care institutions in Canada (excluding stillbirths and cadaveric donor cases). Data includes diagnosis, interventions, special care, length of stay, newborn weights, and gestation weeks at delivery. The Enhanced Clinical Detail File has variables that were created at the Western Libraries Map and Data Centre to act as flags for ICD-10 and CCI groupings, to make using the file easier. Additional variables were created which record the number of ICD-10 and CCI codes assigned to each record in the file. The Geographic Detail File includes inpatient data from all acute care institutions in Canada (excluding stillbirths and cadaveric donor cases). Data includes Health Region, case mix variables, and length of stay. Common data elements in the Clinical Detail and Geographic Detail Files are person identifier, facility province (territories are combined), discharge day, admission day, gender, and age group. The purpose of the DAD sample files is for the researchers to become familiar with the structure and content of DAD data, as well as to explore relationships among data elements. The sample files give researchers the chance to work with the data and clarify data requirements before making a formal data request to CIHI. They are not meant for completing an actual research project. You must read and accept the terms of the license agreement before you can obtain the data and documentation.

出院摘要数据库（Discharge Abstract Database, DAD）用于采集医院出院患者的管理、临床及人口统计学信息。目前提供两类数据集文件：临床详情文件与地理详情文件，二者均从原数据库中抽取10%的个体作为样本，且已为抽样个体随机分配参考日期。临床详情文件涵盖加拿大所有急性医疗护理机构的住院患者数据（排除死产病例与尸体供体病例），数据字段包含诊断信息、干预措施、特殊护理、住院时长、新生儿体重及分娩孕周。增强版临床详情文件包含由西部图书馆地图与数据中心开发的变量字段，这些字段作为国际疾病分类第10版（ICD-10）与查尔森合并症指数（CCI）分组的标识标签，以简化文件使用流程；此外还新增了变量字段，用于记录每条数据记录对应的ICD-10编码与CCI编码数量。地理详情文件同样涵盖加拿大所有急性医疗护理机构的住院患者数据（排除死产病例与尸体供体病例），数据字段包含卫生区域、病例组合变量及住院时长。临床详情文件与地理详情文件共有的数据元素包括：个体标识符、就诊机构所在省份（含合并的地区）、出院日期、入院日期、性别及年龄组。本DAD样本文件的设计目的是帮助研究人员熟悉DAD数据的结构与内容，并探索各数据元素间的关联关系。研究人员可借助此类样本文件，在向加拿大卫生信息研究所（Canadian Institute for Health Information, CIHI）提交正式数据申请前，开展数据实操并明确自身的数据需求。此类样本文件不可用于完成正式研究项目。用户需先阅读并接受许可协议条款，方可获取本数据集及相关文档。
