Impact of CCI and CPET on RARC-ICUD Outcomes

What is it about?

The study aimed to investigate the association between pre-operative comorbidity status measured by the Charlson comorbidity index (CCI) or cardiopulmonary exercise testing (CPET) and postoperative complications and length of stay (LOS) in patients undergoing robot-assisted radical cystectomy and intracorporeal urinary diversion (RARC-ICUD). A retrospective study was conducted on a prospectively maintained database of 428 consecutive patients between 2011 and 2019. A CCI score of 5 or more was associated with a higher rate of postoperative complications. CPET did not predict for complications in the RARC-ICUD population. The study concluded that the CCI score is a simple, reliable, and cost-effective way of identifying patients at increased risk of complications after RARC-ICUD. Surgeons performing RARC-ICUD should consider using CCI to tailor pre-operative patient counseling, improve shared decision-making, and service planning.

Why is it important?

This research is important because it investigates the role of the Charlson comorbidity index (CCI) and cardiopulmonary exercise testing (CPET) in predicting postoperative complications and length of stay (LOS) in patients undergoing robot-assisted radical cystectomy and intracorporeal urinary diversion (RARC-ICUD). Accurate risk prediction is essential to guide patient counselling and facilitate shared decision-making. Key Takeaways: 1. The Charlson comorbidity score is a simple, reliable, and cost-effective approach to identifying patients at increased risk of postoperative complications following RARC-ICUD. 2. A CCI score of >=5 is associated with a higher rate of postoperative complications at 30 and 90 days after RARC-ICUD. 3. CPET did not predict for complications in patients undergoing RARC-ICUD. 4. The most strongly associated factor with increased LOS after RARC-ICUD is the presence of a complication. 5. Surgeons performing robot-assisted radical cystectomy should consider utilizing CCI as a tool to tailor pre-operative patient counselling, improve shared decision-making, and service planning.
