Implementation and Results of a Percutaneous Renal Allograft Biopsy Protocol to Reduce Complication Rate.

Abstract

Percutaneous renal transplant biopsy (PRTB) is the gold standard for evaluating allograft rejection after renal transplant. Hemorrhage is the predominant complication. We describe the implementation of a standardized protocol for PRTB at a single institution, with the aim of reducing bleeding complications. Utilizing the plan-do-study-act model for quality improvement, we created and deployed a protocol centered on controlling patient's hypertension, platelet function, and anticoagulation status. The 4-year study encompassed a total of 880 PRTBs, before and after implementation of the protocol. Total complication rate, which was 5.8% in the 2 years leading up to implementation of the protocol, was reduced to 2.9% after the protocol was introduced (P = .04). A standardized approach to PRTB can potentially lower complication rates; we present a framework for implementating a quality improvement protocol at other institutions.
