背景和目的--为了了解和满足卒中对医疗保健的未来需求，监测是必要的。管理数据是加拿大卒中监测最容易获得的数据来源。国际疾病分类第10版（ICD-10）编码系统在卒中分类方面比ICD-9有潜在的改进。我们的目的是比较医院出院摘要编码使用ICD-9和ICD-10为中风及其risk factors.Methods -我们利用了一个开关的编码系统从ICD-9到ICD-10独立审查中风患者图表。从2000年4月到2001年3月，717张图表，从2002年4月到2003年3月，249张图表被随机选择进行审查。采用前后时间段设计，比较使用ICD-9和ICD-10的卒中（第一部分）和卒中危险因素（第二部分）医院编码的准确性。我们使用了基于ICD-9的中风及其类型的仔细定义，使用了第四和第五位修饰符codes. Results-Stroke编码与ICD-9（90% [CI 95 86至93]正确）和ICD-10（92%[CI 95 88至95正确）与ICD-10同样好。按卒中类型进行编码存在一些差异，尤其是短暂性脑缺血发作，但这些差异无统计学意义。房颤、冠状动脉疾病/缺血性心脏病、糖尿病和高血压被编码为高敏感性（81%至91%）和特异性（83%至100%）。ICD-10是一样好的ICD-9中风危险因素coding.Conclusions -被动监测使用行政数据是一个有用的工具，用于识别中风及其危险因素，使用ICD-9和ICD-10。
Background and Purpose - Surveillance is necessary to understand and meet the future demands stroke will place on health care. Administrative data are the most accessible data source for stroke surveillance in Canada. The International Classification of Diseases, 10th revision (ICD-10) coding system has potential improvements over ICD-9 for stroke classification. Our purpose was to compare hospital discharge abstract coding using ICD-9 and ICD-10 for stroke and its risk factors.Methods - We took advantage of a switch in coding systems from ICD-9 to ICD-10 to independently review stroke patient charts. From time periods April 2000 to March 2001, 717 charts, and from April 2002 to March 2003, 249 charts were randomly selected for review. Using a before-and-after time period design, the accuracy of hospital coding of stroke ( part I) and stroke risk factors ( part II) using ICD-9 and ICD-10 was compared. We used careful definitions of stroke and its types based on ICD-9 using the fourth and fifth digit modifier codes.Results - Stroke coding was equally good with ICD-9 (90% [CI95 86 to 93] correct) and ICD-10 [92% (CI95 88 to 95 correct) with ICD-10. There were some differences in coding by stroke type, notably with transient ischemic attack, but these differences were not statistically significant. Atrial fibrillation, coronary artery disease/ischemic heart disease, diabetes mellitus, and hypertension were coded with high sensitivity (81% to 91%) and specificity (83% to 100%). ICD-10 was as good as ICD-9 for stroke risk factor coding.Conclusions - Passive surveillance using administrative data are a useful tool for identifying stroke and its risk factors using both ICD-9 and ICD-10.
