A coding system was developed to overcome the difficulties encountered in data registry and retrieval from a national audit. In vascular surgery operations are frequently combined, and neither the OHIP fee schedule of codes (Ontario, Canada) nor the ICD-9 system provides sufficient detail for most vascular surgeons to retrieve information for long-term follow-up. However, some wish to record minimal data on their operative procedures. A numeric classification system was developed. A five-digit number is used, the first two digits classifying the operative procedure and anatomic details. Two decimal digits code the classification of operation (e.g., aortic aneurysm, tube graft, aortoiliac, or aortobifemoral) and the final digit may be used as a modifier. "Holes" in the numeric system allow for new operations to be added as they develop. Codes are stored in a database with the following fields: 1) codes; 2) description of operation; 3) translation. The translation field may be modified to permit translation of any existing databases into the system. This database has been distributed with a data registry program free of charge to vascular surgeons in Canada to allow nationwide registry of vascular surgery patients. A numeric code eliminates spelling and abbreviation errors, and can be sufficiently broad-based to allow all surgeons to participate in a nationwide audit.
为克服国家审计中数据登记和检索遇到的困难，开发了一种编码系统。在血管外科手术中，手术常常是联合进行的，加拿大安大略省的OHIP收费代码表和ICD - 9系统都无法为大多数血管外科医生提供足够详细的信息以进行长期随访检索。然而，一些医生希望记录其手术操作的最少数据。于是开发了一种数字分类系统。使用五位数，前两位对手术操作和解剖细节进行分类。两位小数编码手术分类（例如，主动脉瘤、管状移植物、主动脉髂动脉或主动脉双股动脉），最后一位数字可用作修饰符。数字系统中的“空位”允许在新手术出现时添加。代码存储在具有以下字段的数据库中：1）代码；2）手术描述；3）译文。译文字段可进行修改，以便将任何现有数据库翻译成该系统。此数据库已随数据登记程序免费分发给加拿大的血管外科医生，以实现全国范围内血管外科患者的登记。数字代码消除了拼写和缩写错误，并且基础足够广泛，能够让所有外科医生参与全国性审计。
