UNASSIGNED: Using inpatient and outpatient claims data from patients with fee-for-service Medicare from 2010 to 2019, we created a coding algorithm to identify patients with CLTI. To qualify for a CLTI diagnosis, patients had to have either diagnostic codes for peripheral artery disease and for ulceration, infection, or gangrene on the same inpatient or outpatient claim or a CLTI-specific diagnostic code. Patients were also required to have a procedural code indicating arterial vascular testing within 6 months before or after the earliest qualifying CLTI diagnostic code(s). We describe baseline characteristics and long-term outcomes of this cohort.
UNASSIGNED: The final cohort comprised 1,130,065 patients diagnosed with CLTI between 2010 and 2019. Mean (±SD) age of the cohort was 75 ± 5.8 years; 48.4% were women, and 14.6% were Black. Within 30 days of CLTI diagnosis, 20.4% of patients underwent either percutaneous or surgical revascularization. Within 6 months, 3.3% of patients underwent major amputation; 16.7% of patients died within 1 year and 50.3% within 5 years.
UNASSIGNED: We described the development of a cohort of fee-for-service Medicare patients with CLTI using inpatient and outpatient Medicare claims data. CLIPPER will be a resource for developing a set of process measures that can be captured from administrative claims data, with plans to describe their association with limb outcomes and corresponding racial, ethnic, socioeconomic, sex-based, and geographic variability.
■使用2010年至2019年的按服务付费Medicare患者的住院和门诊索赔数据,我们创建了一种编码算法来识别CLTI患者。要获得CLTI诊断的资格,患者必须有外周动脉疾病和溃疡的诊断代码,感染,或同一住院或门诊索赔或CLTI特定诊断代码的坏疽。患者还需要在最早的合格CLTI诊断代码之前或之后的6个月内具有指示动脉血管测试的程序代码。我们描述了该队列的基线特征和长期结果。
■最终队列包括2010年至2019年诊断为CLTI的1,130,065例患者。该队列的平均(±SD)年龄为75±5.8岁;48.4%为女性,黑人占14.6%。CLTI诊断后30天内,20.4%的患者接受经皮或手术血运重建。六个月内,3.3%的患者接受了大截肢;16.7%的患者在1年内死亡,50.3%在5年内死亡。
我们使用住院和门诊医疗保险索赔数据描述了一组CLTI按服务付费医疗保险患者的发展。CLIPPER将成为开发一系列过程措施的资源,这些措施可以从行政索赔数据中捕获,计划描述他们与肢体结果和相应种族的联系,民族,社会经济,基于性别,和地理可变性。
