To assess the validity of using hospital administrative data to measure variations in surgery for early-stage breast cancer, ICD-9-CM coded information was compared with corresponding tumor registry data for 1293 breast cancer patients undergoing lumpectomy or mastectomy at a tertiary referral center from January 1989 to October 1993. Relative to "gold standard" tumor registry data, the administrative data proved 83.4% sensitive and 80.4% specific in identifying women with localized disease who would be potential candidates for lumpectomy. The proportion of women with localized disease undergoing lumpectomy in groups defined by race and insurance status was nearly identical, whichever data were used. Administrative data, which is often readily and publicly available, may be useful in studying variations in breast cancer treatment in key demographic groups.
为评估利用医院管理数据来衡量早期乳腺癌手术差异的有效性,将国际疾病分类第九版临床修订本(ICD-9-CM)编码信息与1989年1月至1993年10月在一家三级转诊中心接受乳房肿瘤切除术或乳房切除术的1293例乳腺癌患者的相应肿瘤登记数据进行了比较。相对于“金标准”肿瘤登记数据,管理数据在识别可能适合进行乳房肿瘤切除术的局限性疾病女性方面,敏感性为83.4%,特异性为80.4%。无论使用哪种数据,按种族和保险状况定义的组中接受乳房肿瘤切除术的局限性疾病女性比例几乎相同。管理数据通常很容易获取且公开可用,可能有助于研究关键人口群体中乳腺癌治疗的差异。
