Does the Veterans Affairs Risk Analysis Index Overestimate Frailty in Patients With Localized Prostate Cancer?

Area of Science:

• Urology
• Surgical Oncology
• Geriatrics

Background:

• The Veterans Affairs (VA) Health System uses the Risk Analysis Index (RAI) to assess surgical frailty.
• Elevated RAI scores can lead to a "surgical pause" and geriatric consultation.
• Cancer diagnoses, including prostate cancer (PCa), can inflate RAI scores, potentially misrepresenting patient frailty.

Purpose of the Study:

• To investigate if low- or intermediate-risk PCa diagnosis correlates with 30-day morbidity and mortality predicted by RAI.
• To determine if excluding PCa from RAI calculations provides a more accurate surgical risk assessment.

Main Methods:

• Retrospective review of 130 patients undergoing radical prostatectomy for low- or intermediate-risk PCa.
• RAI-Administrative (RAI-A) scores calculated with and without PCa diagnosis.
• Comparison of actual 30-day postoperative complications and mortality with RAI-predicted rates.

Main Results:

• Mean RAI-A excluding PCa was 8.58, increasing to 24.95 when PCa was included.
• RAI-A predicted complication rates of 4.6% (2.5% severe) without PCa vs. 11.2% (5.6% severe) with PCa.
• Actual 30-day complications occurred in 4.6% of patients, with no severe (grade IV-V) complications.

Conclusions:

• Including localized PCa in RAI-A calculations overestimates surgical frailty and predicted morbidity.
• Excluding PCa diagnosis may offer a more precise surgical risk evaluation for these patients.
• This adjustment could prevent unnecessary surgical delays for low- and intermediate-risk PCa patients.
