BACKGROUND Patients undergoing hip or knee replacement are at high risk of developing a postoperative venous thromboembolism even after discharge from hospital. We sought to identify hospital and patient characteristics associated with receiving thromboprophylaxis after discharge and to compare the risk of short-term mortality among those who did or did not(More)
OBJECTIVE States vary greatly in their support for home- and community-based services (HCBS) that are intended to help disabled seniors live in the community. This article examines how states' generosity in providing HCBS affects the risk of nursing home admission among older Americans and how family availability moderates such effects. METHODS We(More)
OBJECTIVE Understanding of the effects of providers' cost on regional variation in healthcare spending is still very limited. The objective of this study is to assess cross-state and cross-region variations in inpatient cost of lower extremity amputation among diabetic patients (DLEA) in relation to patient, hospital, and state factors. METHODS Patient(More)
STUDY OBJECTIVE The aim of the study was to evaluate the impact of prospective review of significant drug-drug interactions (DDIs) occurring in medical intensive care unit (MICU) patients by the critical care pharmacist participating in patient care rounds on improvement of safer and more efficacious medication use. STUDY DESIGN A prospective consecutive(More)

In this paper, we propose a fast MPI algorithm for Monte Carlo approximation PageRank vector of all the nodes in a graph, named Fast Fibonacci Series-Based Personal PageRank. In the latter paper we will call it FFSB algorithm for short. The basic ideal is very efficiently computing single random walks of a given length starting at each node in a graph. More(More)
