We quantified the current and historical incidence of periprosthetic infection associated with hip and knee arthroplasty in the United States using the Nationwide Inpatient Sample, as well as corresponding hospitalization charges and length of stay. The rate of infected knee arthroplasties was 0.92%, significantly greater than that of infected hip(More)
This study characterizes the patient and clinical factors influencing the economic burden of periprosthetic joint infection (PJI) in the United States. The 2001-2009 Nationwide Inpatient Sample was used to identify total hip and knee arthroplasties using International Classification of Diseases, Ninth Revision, procedure codes. The relative incidence of PJI(More)
BACKGROUND To assess the patient-reported use of caregiving among individuals with age-related macular degeneration (AMD) and evaluate the impact of visual impairment level on this use. METHODS A survey including the AMD Health and Impact Questionnaire and the Daily Living Tasks Dependent on Vision Questionnaire (DLTV) was mailed to members of the Macular(More)
BACKGROUND Little is known about cost implications of anemia and its association with mortality in chronic obstructive pulmonary disease (COPD). This claims analysis addresses these questions. METHODS Using the the US Medicare claims database (1997-2001), this study identified Medicare enrollees with an ICD-9 diagnosis of COPD. Concomitant anemia was(More)
BACKGROUND A patient report of respiratory symptoms in COPD is essential to successfully monitoring disease, adjusting treatment, and evaluating outcomes. OBJECTIVE To develop empirically based guidelines for interpreting mean changes in symptom scores using the Breathlessness, Cough, and Sputum Scale (BCSS). METHODS Analyses were performed on data from(More)
OBJECTIVES This article updates, through 1996, a previously published bibliography of health-care cost-benefit and cost-effectiveness analysis, which described the literature from 1979 to 1990. METHODS A systematic search of MEDLARS databases was conducted for all articles falling under the medical subject headings "cost-benefit analysis" (which includes(More)
BACKGROUND The burden of inadequately controlled pediatric asthma on education and other daily activities is not well described. OBJECTIVE To evaluate asthma-related activity limitations and productivity losses among children and caregivers. METHODS Surveys were mailed to caregivers of children with asthma.

The purpose of the present study is to determine the differences in cost, complications, and mortality between knee arthroplasty (TKA) patients who stay the standard 3-4 nights in a hospital compared to patients who undergo an outpatient procedure, a shortened stay or an extended stay. TKA patients were identified in the Medicare 5% sample (1997-2009) and(More)
Background: The impact of acute exacerbations of chronic bronchitis (AECB), a common consequence of chronic obstructive pulmonary disease (COPD), is extensive, with symptoms ranging from mild to life threatening. Health-related quality of life (HRQL) is impaired in patients with COPD, but little is known about the direct effect of exacerbations on HRQL.(More)
