BACKGROUND Asthma is a common and costly health condition, but most estimates of its economic effect have relied on secondary sources with limited condition-specific detail. OBJECTIVE We sought to estimate the magnitude of direct and indirect costs of adult asthma from the perspective of society. METHODS We used cross-sectional survey data from an(More)
BACKGROUND Previous reports have suggested that hospital resource utilization for revision total hip arthroplasty is substantially higher than that for primary total hip arthroplasty. However, current United States Medicare hospital-reimbursement policy does not distinguish between the two procedures. The purpose of this study was to compare primary and(More)

One of the major challenges of assessing quality of life is the high likelihood that after a stroke a patient will not be able to complete such an assessment. One practical solution is to have a family caregiver complete the assessment(More)

Although concurrent models have better predictive power than prospective models, the large payments associated with concurrent RA create incentives for fraudulent coding. A hybrid strategy--in which prospective payments were used for(More)
