The impact of hospital safety-net status on inpatient outcomes for brain tumor craniotomy: a 10-year nationwide analysis.

ABSTRACT:

Background

Outcome disparities have been documented at safety-net hospitals (SNHs), which disproportionately serve vulnerable patient populations. Using a nationwide retrospective cohort, we assessed inpatient outcomes following brain tumor craniotomy at SNHs in the United States.

Methods

We identified all craniotomy procedures in the National Inpatient Sample from 2002-2011 for brain tumors: glioma, metastasis, meningioma, and vestibular schwannoma. Safety-net burden was calculated as the number of Medicaid plus uninsured admissions divided by total admissions. Hospitals in the top quartile of burden were defined as SNHs. The association between SNH status and in-hospital mortality, discharge disposition, complications, hospital-acquired conditions (HACs), length of stay (LOS), and costs were assessed. Multivariate regression adjusted for patient, hospital, and severity characteristics.

Results

304,719 admissions were analyzed. The most common subtype was glioma (43.8%). Of 1,206 unique hospitals, 242 were SNHs. SNH admissions were more likely to be non-white (P < .001), low income (P < .001), and have higher severity scores (P = .034). Mortality rates were higher at SNHs for metastasis admissions (odds ratio [OR] = 1.48, P = .025), and SNHs had higher complication rates for meningioma (OR = 1.34, P = .003) and all tumor types combined (OR = 1.17, P = .034). However, there were no differences at SNHs for discharge disposition or HACs. LOS and hospital costs were elevated at SNHs for all subtypes, culminating in a 10% and 9% increase in LOS and costs for the overall population, respectively (all P < .001).

Conclusions

SNHs demonstrated poorer inpatient outcomes for brain tumor craniotomy. Further analyses of the differences observed and potential interventions to ameliorate interhospital disparities are warranted.

Project description:BackgroundHospitals with safety-net status have been associated with inferior surgical outcomes and higher costs. The mechanism of this discrepancy, however, is not well understood. We hypothesized that discrepant rates of failure to rescue after complications of routine cardiac surgery would explain the observed inferior outcomes at safety-net hospitals.MethodsThe National Inpatient Sample was used to identify adult patients who underwent elective coronary artery bypass grafting and isolated or concomitant valve operations between January 2005 and December 2016. Hospitals were stratified into low-, medium-, or high-burden categories based on the proportion of uninsured or Medicaid patients to emulate safety-net status as defined by the Institute of Medicine. Failure to rescue was defined as mortality after occurrence of neurologic, cardiovascular, respiratory, renal, or infectious complications (major and minor complications). Multivariable regression was used to perform risk-adjusted comparisons of the rate of complications, failures to rescue, and resource use for high-burden hospitals versus low-burden and medium-burden hospitals.ResultsOf an estimated 2,012,104 patients undergoing elective major cardiac operations, 2% died, whereas 36% suffered major and minor complications. Safety-net hospitals had higher odds of failure to rescue after major comorbidity (adjusted odds ratio 1.12, 95% confidence interval 1.01-1.23). Occurrence of major and minor complications at safety-net hospitals was associated with increased costs ($2,480 [95% confidence interval $1,178-$3,935]) compared with low-burden hospitals.ConclusionSafety-net hospitals were associated with higher rates of failure to rescue after occurrence of tamponade, septicemia, and respiratory complications. Implementation of care bundles to tackle cardiovascular, respiratory, and renal complications may affect the discrepancy in incidence of and rescue from complications at safety-net institutions.

Project description:OBJECTIVES:The influence of obesity on the outcomes of curative liver resection for malignancies remains controversial. We aimed to compare the in-hospital outcomes of liver resection for malignancy between obese and non-obese patients. DESIGN:This was a population-based, retrospective, observational study using data from the Nationwide Inpatient Sample (NIS), the largest all-payer US inpatient care database. SETTING:Hospitalisations of adults ≥18 years old with diagnoses of primary hepatobiliary malignancy or secondary malignant neoplasms of liver in the USA were identified from the NIS database between 2005 and 2014. PARTICIPANTS:Data of 18 398 patients ≥18 years old and underwent liver resection without pancreatic resection in the NIS were extracted. All included subjects had primary hepatobiliary malignancy or secondary malignant neoplasms of the liver. Patients were divided into obese and non-obese groups. These groups were compared with respect to postoperative complications, length of hospital stay and hospital cost according to surgical extent and approach. INTERVENTIONS:Patients were undergoing lobectomy of liver or partial hepatectomy. PRIMARY AND SECONDARY OUTCOME MEASURES:The primary endpoints of this study were postoperative complications, length of hospital stay and hospital cost. RESULTS:After adjustment, obese patients were significantly more likely to experience postoperative complications than were non-obese patients (adjusted OR 1.25, 95% CI 1.10 to 1.42), regardless of whether lobectomy or partial hepatectomy was performed. Furthermore, obesity was significantly associated with increased risk of postoperative complications in patients who underwent open liver resection, but not laparoscopic resection. No significant difference was observed in length of hospital stay or total hospital costs between obese and non-obese patients. CONCLUSIONS:After adjustment for preoperative comorbidities and other potential confounders, obesity is significantly associated with greater risk of complications in patients undergoing open liver resection for malignancy, but not laparoscopic resection.
