DATA SOURCES We used the MEDLINE data base to search for all English language papers evaluating the effectiveness of bed rest in pregnancy. We also(More)
From 1986 through 1992, the Health Care Financing Administration (HCFA) released information comparing patient death rates at individual hospitals. This was viewed widely as an effort to aid consumers in selecting hospitals. This study evaluates how the release of this information affected hospital utilization, as measured by discharges. It finds a very(More)
OBJECTIVE To perform a decision analysis to understand better the implications of 19 potential group B streptococcus screening and treatment strategies. METHODS We searched the literature to locate appropriate articles from which to derive probability estimates. Using decision analysis, we determined the likely outcomes of 19 group B streptococcus(More)
Arteriovenous graft thrombosis is a frequent event in hemodialysis patients, and usually occurs in grafts with significant underlying stenosis. Regular surveillance for graft stenosis, with pre-emptive angioplasty of significant lesions, may improve graft outcomes. This prospective, randomized, clinical trial allocated 126 hemodialysis patients with grafts(More)
BACKGROUND The objective of this study was to determine whether the use of ultrasound and percutaneous breast biopsies in patients with screen-detected nonpalpable abnormalities can reduce benign open surgical biopsies of the breast without increasing cost or sacrificing detection of potentially curable breast carcinomas. METHOD Using a computerized(More)
OBJECTIVES We examined whether cocaine-dependent homeless persons had stable housing and were employed 6, 12, and 18 months after they entered a randomized controlled trial comparing 2 treatments. METHODS One group (n = 103) received abstinence-contingent housing, vocational training, and work; another group (n = 103) received the same intervention plus(More)
BACKGROUND Several reviews of the effectiveness of drug abuse treatment have concluded that treatment works. However, studies analyzing cost-effectiveness or cost-benefits of drug treatment have been limited. Consequently, policy decisions regarding substance abuse treatment have utilized educated guesses or consensus of experts in the absence of controlled(More)
BACKGROUND AND OBJECTIVE The Health Information Technology for Economic and Clinical Health (HITECH) Act has distributed billions of dollars to physicians as incentives for adopting certified electronic health records (EHRs) through the meaningful use (MU) program ultimately aimed at improving healthcare outcomes. The authors examine the extent to which the(More)
In economic evaluations of health treatments, the sensitivity of a cost-benefit (CB), cost-effectiveness (CE) or cost-utility (CU) analysis to changes in modeling assumptions, variation in data, and sampling error is important. The typical approach to this problem is ad hoc experimentation; namely, a few parameters of particular interest are changed, either(More)
OBJECTIVE To determine if the occurrence of health outcomes following clinical laboratory testing can be used to identify types of laboratories that may be having higher than expected error rates. DESIGN Retrospective analysis of Medicare Part B outpatient claims, Part A hospitalization bills, and death records using a case-control study. SETTING(More)
