Objective: The purpose of this study is to assess patient-reported outcomes after renal tumor ablation.

Materials and methods: A retrospective review of a pilot quality initiative from February 2016 to April 2016 in our renal ablation practice was performed to assess outcomes after treatment. This included a total of 38 patients (mean age, 63 years; range, 39-83 years) undergoing renal ablation procedures. This pilot included the quantification of recovery, pain, physical well-being, interference with social activities, and physical function as reported by the patient, including measures obtained from the National Institutes of Health's Patient-Reported Outcome Measurement Information System (PROMIS). Such measures were obtained within 24 hours before ablation and days 1-7 and 30 after ablation.

Results: The mean numeric rating (0-10) pain scores at 1 and 2 days after treatment were 1.8 (SD, 2.3) and 2.6 (SD, 2.5). Similarly, mean scores for both overall physical well-being and social activities declined by less than 2 points in the days after ablation. PROMIS scales for physical function and social activities showed very little change from baseline. Nearly 50% of patients thought that they had completely recovered from the ablation on the day after treatment; this perception of recovery declined at days 3-5 and then increased to 89% at 30 days after ablation.

Conclusion: This pilot study shows the feasibility of capturing patient-reported outcomes after renal ablation. Such information, particularly when collected from a broader patient population, will be valuable in providing a means to measure quality in the ablation practice and in improving patient education regarding treatment.
