OBJECTIVE: The study aimed to identify risk factors associated with in-hospital mortality among patients with malignant solid tumors. METHODS: Using data from the Nationwide Inpatient Sample 2012, we identified patients (n=330,871) with at least one diagnosis of malignant solid tumor using the International Classification of Diseases, ninth edition...
Conference Paper
OBJECTIVES: Depressive and anxiety disorders are the most common mental disorders and are very common among individuals with a history of military service. The aims of this study were to examine the prevalence of depression among respondents with a history of military service, and examine if self-reported lifetime depression diagnosis in veterans d...
Conference Paper
OBJECTIVES: Depressive and anxiety disorders are the most common mental disorders and often lead to costly mental distress in the US. The aim of this study was to determine if there are variations in the geographic distribution of self-reported lifetime depression using data from the 2012 Behavior Risk Factor Surveillance System (BRFSS). METHODS: D...
Article
Objective To evaluate the cost-effectiveness of adenotonsillectomy (T&A) for adenotonsillar hypertrophy and recurrent tonsillitis through the use of Missouri Medicaid data. Study design Children ages 2-16 years who had a diagnosis of adenotonsillar hypertrophy (based on medical claim codes) in 2006 (n = 4276) were included in this population-based...
Article
Ascites are the most common complication of cirrhosis. Evidence-based guidelines define the criteria and standards of care for patients with cirrhosis and ascites. However, little is known about the extent to which patients with ascites meet these standards. We evaluated the quality of ascites care, measured by 8 explicit Delphi panel-derived quali...
Article
To find the survival rate of patients ≥ 80 years old who undergo salvage surgery for squamous cell carcinoma of the larynx. National data registry analysis. Seventeen population-based registries comprising the National Cancer Institute's Surveillance, Epidemiology, and End Results database. Overall, cancer-specific, and relative survival rates were...
Article
The complement-dependent microcytotoxicity crossmatch (CDCXM) is a standard method for evaluating the presence of preformed antibodies before transplantation. The flow cytometry crossmatch (FCXM) is more sensitive, but there is controversy regarding translation of its increased sensitivity to clinically relevant graft outcomes. We analyzed Organ Pr...
Article

Medicare has proposed quality-of-care indicators for chronic hepatitis C virus (HCV) infection. The extent to which these standards are met in practice is largely unknown. To evaluate the quality of health care that patients with HCV receive and the factors associated with receipt of quality care. Retrospective cohort study. Nationwide U.S. health...
Article
Full-text available
We examined the relationship between the total cost incurred by liver transplantation (LT) recipients and their Model for End-Stage Liver Disease (MELD) score at the time of transplant. We used a novel database linking billing claims from a large private payer with the Organ Procurement and Transplantation Network registry. Included were adults who...
Article
Chronic kidney disease (CKD) can have a negative impact on the natural history of hepatitis C virus infection (HCV) infection; patients with HCV and CKD often have adverse outcomes. We evaluated a large and geographically diverse group of patients to determine whether HCV status has an independent effect on the risk of developing CKD. We conducted...
Article
Retrospective comparison of treatment-related kidney transplant outcomes may be facilitated by multivariable statistical adjustments and case-matching. We studied Organ Procurement and Transplantation Network registry data for kidney transplants in 2001 to 2005 managed with thymoglobulin, basiliximab, or no antibody induction and discharge maintena...
Article
Full-text available
Billing claims are increasingly examined beyond administrative functions as outcomes measures in observational research. Few studies have described the performance of billing claims as surrogate measures of clinical events among kidney transplant recipients. We investigated the sensitivity of Medicare billing claims for clinically verified cardiova...
Article
Full-text available
Whether to include additional comorbidities beyond diabetes in future kidney allocation schemes is controversial. We investigated the predictive ability of multiple pretransplant comorbidities for graft and patient survival. We included first-kidney transplant deceased donor recipients if Medicare was the primary payer for at least one year pretran...
Article
Full-text available
Use of induction for renal transplantation is controversial because of the concerns about long-term safety and efficacy. We compared the safety and efficacy at 10 years among patients randomized to thymoglobulin or Atgam induction in a single center, randomized, double-blinded trial. Quality-adjusted life years (QALYs) were calculated using utility...
