Primary

MeasureTime frameDescription
Ability to reach medical suitability for renal transplant within 18 months after initiating treatment and the change and trajectory of health-related quality of life (HRQOL)18 monthsOutcomes will be measured based on weight loss and a variety of validated surveys and questionnaires to measure HRQOL

Secondary

MeasureTime frameDescription
All-cause mortality5 yearsNumber of patients who die from any cause
Weight loss5 yearsAmount of weight lost at various points over the study period
Surgical outcomes5 yearsIncidence of surgical complications including but not limited to leak rate, stricture rate, pulmonary embolism, and infection.
