Temporal trends of failure-to-rescue following perioperative complications in vulvar cancer surgery in the United States.

Abstract

OBJECTIVE:

Failure-to-rescue, defined as mortality following a perioperative complication, is a perioperative quality indicator studied in various surgeries, but not in vulvar cancer surgery. The objective of this study was to assess failure-to-rescue in patients undergoing surgical therapy for vulvar cancer.

METHODS:

This cross-section study queried the National Inpatient Sample. The study population was 31,077 patients who had surgical therapy for vulvar cancer from 1/2001-9/2015. The main outcomes were (i) perioperative morbidity (29 indicators) and (ii) mortality following a perioperative complication during the index admission for vulvar surgery (failure-to-rescue), assessed with a multivariable binary logistic regression model.

RESULTS:

The cohort-level median age was 69 years, and 14,337 (46.1%) had medical comorbidity. Perioperative complications were reported in 4736 (15.2%) patients during the hospital admission for vulvar surgery. In multivariable analysis, patient factors including older age, medical comorbidity, and morbid obesity, and treatment factors with prior radiotherapy and radical vulvectomy were associated with perioperative complications (P < 0.05). The number of patients with morbid obesity, higher comorbidity index, and prior radiotherapy increased over time (P-trends < 0.001). Among 4736 patients who developed perioperative complications, 55 patients died during the hospital admission for vulvar surgery (failure-to-rescue rate, 1.2%). In multivariable analysis, cardiac arrest (adjusted-odds ratio [aOR] 27.25), sepsis or systemic inflammatory response syndrome (aOR 11.54), pneumonia (aOR 6.03), shock (aOR 4.37), and respiratory failure (aOR 3.10) were associated with failure-to-rescue (high-risk morbidities). There was an increasing trend of high-risk morbidities from 2.0% to 3.7% over time, but the failure-to-rescue from high-risk morbidities decreased from 9.1% to 2.8% (P-trend < 0.05).

CONCLUSION:

Vulvar cancer patients undergoing surgical treatment had increased comorbidity over time with an increase in high-risk complications. However, failure-to-rescue rate has decreased significantly.
