Hospital-acquired conditions after surgery for gynecologic cancer - An analysis of 82,304 patients.

Objective: To evaluate the hospital-acquired condition (HAC) following oophorectomy and/or hysterectomy for gynecologic cancer patients based on clinical outcomes and costs.
Materials and Methods: Data were obtained from the Nationwide Inpatient Sample from 2005 to 2011. Chi-squared and Wilcoxon rank sum two-sample tests and multivariate logistic regression model were used for statistical analysis.
Results: Of 82,304 women (median age: 60 years, range: 1-101), 49,386 (60.0%) had endometrial, 23,510 (28.6%) had ovarian, and 9408 (11.4%) had cervical cancers. Of 135 HAC events, these involved catheter-associated urinary tract infections (n = 47), vascular catheter-associated infection (n = 41), foreign object retained after surgery (n = 19), pressure ulcers (n = 16), manifestation of poor glycemic control (n = 10), and air embolism (n = 2). Older patients (≥60 years) experienced more HACs relative to younger (0.23% vs. 0.09%; OR = 2.13, 95% CI: 1.30-3.50; p = 0.003), and patients with Medicaid experienced more HACs compared to those with private insurance (0.35% vs. 0.10%; OR = 3.09, 95% CI: 1.70-5.62; p < 0.001). Laparoscopic surgeries were associated with less HACs compared to open surgeries (0.05% vs. 0.19%; OR = 0.41, 95% CI: 0.19-0.90; p = 0.03). Length of hospitalization and hospital charges were greater for those with HACs, (12 days vs. 3 days; p < 0.001; $89,324 vs. $31,107; p < 0.001), respectively.
Conclusion: The odds of hospital-acquired conditions were higher in older patients, open surgery, Medicaid insured with higher associated hospital charges.
