In-hospital mortality and failure-to-rescue rates after radical cystectomy

Abstract

Objective: To show the underlying variability in peri-operative mortality after radical cystectomy (RC) by analysing failure-to-rescue (FTR) rates, i.e. deaths after complications.

Materials and methods: Patients undergoing RC for non-metastatic bladder cancer (BCa) were identified from the Nationwide Inpatient Sample, 1999-2009, resulting in a weighted estimate of 79,972 patients. The FTR rates were assessed according to patient and hospital characteristics, as well as complication type. Generalized linear regression analyses were performed.

Results: Overall, 26,740 patients had a complication, corresponding to a FTR rate of 5.5%. Septicaemia (odds ratio [OR]: 13.41, P < 0.001) and cardiac (OR: 3.97, P < 0.001), wound-related (OR: 2.12, P < 0.001), genitourinary (OR: 1.62, P = 0.045) and haematological (OR: 1.78, P = 0.008) complications were associated with FTR. Older age (OR: 1.05, P < 0.001), increasing comorbidities (OR: 1.33, P < 0.001), Medicare (OR: 1.52, P = 0.016), and Medicaid insurance status (OR: 2.10, P = 0.029) were associated with higher odds of FTR. Conversely, increasing hospital volume (OR: 0.992, P = 0.014) reduced the odds of FTR.

Conclusions: Whereas both patient and hospital characteristics were associated with increased odds of FTR, the occurrence of septicaemia and cardiac complications were the most strongly associated with a higher risk of in-hospital mortality.
