OBJECTIVES Many physicians debate the efficacy of mechanical thrombectomy for ischaemic stroke, but most agree that to establish potential benefit, patient selection must be examined further. People >80 years are a growing population of patients with ischaemic stroke but are largely excluded from clinical trials. The benefit of thrombectomy for them may be greatly reduced due to diminishing neu...

HYPOTHESIS Operative mortality rates for esophageal resection vary across hospital volume groups in a nationally representative sample of hospitals. DESIGN Cross-sectional study of all adult patients in the Nationwide Inpatient Sample who underwent esophageal resection from 1995 through 1999 (N = 3023). Operative mortality was determined for hospital volume quartiles (low, <3 per year; medium...

BACKGROUND AND PURPOSE We have previously reported the difference in length of stay and hospital charges for patients with cerebral aneurysms treated with either clipping or coiling at our institution. We now report an analysis of the same comparison at a national level conducted using the Nationwide Inpatient Sample database. METHODS We obtained the Nationwide Inpatient Sample from the Healt...

Background and Purpose—We have previously reported the difference in length of stay and hospital charges for patients with cerebral aneurysms treated with either clipping or coiling at our institution. We now report an analysis of the same comparison at a national level conducted using the Nationwide Inpatient Sample database. Methods—We obtained the Nationwide Inpatient Sample from the Healthc...

US inpatient capacity increased until the 1970s, then declined. The US Census Bureau expects the population aged ≥65 years to more than double by 2050. The implications for national inpatient capacity requirements have not been quantified. Our objective was to calculate the number of hospital admissions that will be necessitated by population aging, ceteris paribus. We estimated 2011 nationwide...

METHOD: Nationwide Inpatient Sample (2006–2011) was queried to identify bilateral breast reduction cases. Patients with rheumatoid arthritis, systemic lupus erythematosus, Sjogren’s syndrome, Raynaud’s syndrome, psoriatic arthritis, or scleroderma were identified. Demographic factors, comorbidities, and postoperative complications were compared to patients without CTD using student t-test, chi-...

The main goals of this paper are to provide formal characterizations of comovement that are useful empirically in health economics applications and to demonstrate the utility of some of these measures via applications to volume-outcome question using data from the 2005 Nationwide Inpatient Sample. Specifically, the paper focuses on the concepts of quadrant dependence and association and their o...
