668 Introduction of a Pre-Operative Assessment Clinic for Elective Procedures in a Renal Replacement Therapy Unit - Analysis of Effect on Cancellation of Procedures

Abstract

Abstract Aim In September 2020, our Renal and Transplant unit introduced a new formalised protocol for Pre-Operative Assessment Clinics (POACs), led by SHO-grade junior doctors. This study aims to investigate the efficacy of the new protocol. Method All elective operations including dialysis access procedures, transplant urology, parathyroidectomies and hernia repairs conducted by a single renal replacement therapy unit were examined over an 18-month period prior to POAC implementation, then a 12-month period following implementation. Living donor transplants and nephrectomies were excluded. On-the day (OTD) cancellation causes were analysed and categorised into: Results Total cases performed: Pre-implementation = 921, post-implementation = 415. OTD cancellations: Pre-implementation - total of 211/921 (22.9%). 90 (9.8%) were due to predictable patient factors, 54 (5.9%) for unpredictable patient factors and 67 (7.2%) for hospital factors. Post-implementation - total of 58/415 (11.6%). 32 (7.7%) for unpredictable patient factors and 12 (2.9%) for hospital factors. Four (1%) were cancelled for predictable patient factors, two due to patients presenting with hypertension. Conclusions Patients with renal failure have multiple co-morbidities. Optimising pre-operative care is crucial to ensure they receive timely treatment. This audit has demonstrated that a redesigned POAC led to a reduction of OTD cancellation rates from 22.9% to 11.6%, with a marked reduction in predictable causes for cancellations. Further improvements and re-audit are planned.
