Clinical Trial Summary

Retrospective cohort study

Description:

Data source and study cohort:

We conducted a retrospective cohort study using the Premier Healthcare Database (PHD, Premier Inc., Charlotte, NC), an extensive, US hospital-based, all-payer database representing approximately 20% of annual United States inpatient discharges at community and academic centers. The International Classification of Diseases, ninth revision (ICD-9), and tenth revision (ICD-10) procedure codes were used to identify patients who had undergone elective kidney cancer surgery between the 15 years of study from 2003 to 2017. The cohort was then restricted based on appropriate ICD-9 and ICD-10 diagnosis codes to ensure that surgery was performed for a kidney mass. The study cohort was also limited to adult patients (age >= 18 years), "elective" cases based on administrative codes, as well as surgery on hospital day zero or one to minimize outlier patients who could skew the surgical outcomes.

Outcomes:

The primary outcome of this study was the 90-day complication rate. Complication rates were based on the Clavien-Dindo classification of surgical complications and divided into four categories: no complications, minor complications (Clavien grades 1, 2), and non-fatal major complications (Clavien grades 3, 4), and mortality (Clavien grade 5). Clinical systems also categorized complications (bleeding, cardiac, endocrine, gastrointestinal, infection, neurology, pulmonary, renal, soft tissue, urologic, venous thromboembolism) using Health Care Cost and Utilization Project Clinical Classification Software Level II or III designations; of note, the category for "surgical" complications was excluded given that all complications captured in this analysis are considered surgical complications. Secondary outcomes included patient disposition, length of hospital stay, and readmission rate.
