CONTEXT Back and neck problems are among the symptoms most commonly encountered in clinical practice. However, few studies have examined national trends in expenditures for back and neck problems or related these trends to health status measures. OBJECTIVES To estimate inpatient, outpatient, emergency department, and pharmacy expenditures related to back(More)
STUDY DESIGN Prospective cohort study of randomly selected Veterans Affairs out-patients without baseline low back pain (LBP). OBJECTIVE To determine predictors of new LBP as well as the 3-year incidence of magnetic resonance imaging (MRI) findings. SUMMARY OF BACKGROUND DATA Few prospective studies have examined clinical and anatomic risk factors for(More)
BACKGROUND AND PURPOSE Proton MR spectroscopy ((1)H-MR spectroscopy) is a potentially useful adjunct to anatomic MR imaging in the characterization of brain tumors. We performed an updated systematic review of the evidence. METHODS We employed a standardized search strategy to find studies published during 2002-2004. We reviewed studies measuring(More)
BACKGROUND Vertebroplasty is commonly used to treat painful, osteoporotic vertebral compression fractures. METHODS In this multicenter trial, we randomly assigned 131 patients who had one to three painful osteoporotic vertebral compression fractures to undergo either vertebroplasty or a simulated procedure without cement (control group). The primary(More)
BACKGROUND We sought to determine whether 16-slice multidetector CT angiography (CTA) has sufficient negative predictive value for use as the initial imaging examination for patients with suspected blunt carotid and vertebral artery injury (BCVI) and to estimate the positive predictive value of different screening criteria in assessing BCVI. STUDY DESIGN(More)
We used magnetic resonance imaging (MRI) to assess lumbar lordosis in 27 patients with low back pain and 19 patients and 10 volunteers with no known back pain. Our study aimed to investigate whether lordosis changes with age and is reduced in those with low back pain. Although our results confirm known observations that lumbar lordosis is more prominent in(More)
PURPOSE To elicit preference values for health states associated with Stage III colon cancer (CRC) and to explore the effect of neuropathy associated with current adjuvant treatment. METHODS We used time trade-off (TTO) techniques to elicit preferences from 49 CRC patients and 49 community members. We elicited preferences for 7 health states: remission;(More)
OBJECTIVE Harmful alcohol consumption is a leading cause of death in the United States. The majority of people who die from alcohol use begin drinking in their youth. In this study, we estimate the impact of interventions to reduce the prevalence of drinking among youth on subsequent drinking patterns and alcohol-attributable mortality. METHOD We first(More)
BACKGROUND With the decrease in junior doctor hours, the advent of specialist registrars, and the availability of highly trained and experienced nursing personnel, the service needs of patients with chronic respiratory diseases attending routine outpatient clinics may be better provided by appropriately trained nurse practitioners. METHODS A randomised(More)
BACKGROUND AND OBJECTIVE The Washington State workers' compensation agency funded a coverage with evidence development study to evaluate spinal cord stimulation (SCS) for chronic back and leg pain after spine surgery (failed back surgery syndrome). We previously published the study outcomes. We now report results from a second patient cohort; study costs;(More)
