      BACKGROUND: The SPORT (Spine Patient Outcomes Research Trial) reported favorable surgery outcomes over 2 years among patients with stenosis with and without degenerative spondylolisthesis, but the economic value of these surgeries is uncertain.

      OBJECTIVE: To assess the short-term cost-effectiveness of spine surgery relative to nonoperative care for stenosis alone and for stenosis with spondylolisthesis.

      DESIGN: Prospective cohort study.

      DATA SOURCES: Resource utilization, productivity, ...

      Abstract: The objective of the study was to estimate the impact of hip and vertebral fractures on quality of life in postmenopausal women using a preference-based health measure that is appropriate for economic evaluations and to investigate correlates of health outcome. Interviews to assess health-related quality of life, which also documented other health conditions and characteristics, were undertaken in women age 50 years and older without osteoporotic fractures compared with women ...

      STUDY DESIGN: A reliability assessment of standardized magnetic resonance imaging (MRI) interpretations and measurements.

      OBJECTIVE: To determine the intra- and inter-reader reliability of MRI features of lumbar spinal stenosis (SPS), including severity of central, subarticular, and foraminal stenoses, grading of nerve root impingement, and measurements of cross-sectional area of the spinal canal and thecal sac.

      SUMMARY OF BACKGROUND DATA: MRI is commonly used to assess patients with ...

      STUDY DESIGN: Assessment of the reliability of standardized magnetic resonance imaging (MRI) interpretations and measurements.

      OBJECTIVE: To determine the intra- and inter-reader reliability of MRI parameters relevant to patients with intervertebral disc herniation (IDH), including disc morphology classification, degree of thecal sac compromise, grading of nerve root impingement, and measurements of cross-sectional area of the spinal canal, thecal sac, and disc fragment.

      PURPOSE: To characterize the inter- and intraobserver variability of qualitative, non-disk contour degenerative findings of the lumbar spine at magnetic resonance (MR) imaging.

      MATERIALS AND METHODS: The case accrual method used to perform this institutional review board-approved, HIPAA-compliant retrospective study was the random selection of 111 interpretable MR examination cases of subjects from the Spine Patient Outcomes Research Trial. The subjects were aged 18-87 years (mean, 53 ...

      Several histologic classifications for breast ductal carcinoma in situ (DCIS) have been proposed. This study assessed the diagnostic agreement and reproducibility of three DCIS classifications (Holland [HL], modified Lagios [LA], and Van Nuys [VN]) by comparing the interpretations of pathologists without expertise in breast pathology with those of three breast pathology experts, each a proponent of one classification. Seven nonexpert pathologists in New Hampshire and three experts ...

      BACKGROUND: Several studies have reported lower perioperative mortality rates with pancreaticoduodenectomy at high-volume hospitals than at low-volume hospitals. We sought to determine whether volume is also related to survival after hospital discharge.

      METHODS: Using information from the Medicare claims database, we performed a retrospective cohort study of all 7229 patients over age 65 undergoing pancreaticoduodenectomy in the United States between 1992 and 1995. We divided the study ...

      OBJECTIVE: To determine whether exposure to repetitive head impacts over a single season negatively affects cognitive performance in collegiate contact sport athletes.

      METHODS: This is a prospective cohort study at 3 Division I National Collegiate Athletic Association athletic programs. Participants were 214 Division I college varsity football and ice hockey players who wore instrumented helmets that recorded the acceleration-time history of the head following impact, and 45 noncontact ...

      Purpose: To compare societal values across health-state classification systems and to describe the performance of these systems at baseline in a large population of persons with confirmed diagnosis of intervertebral disc herniation (IDH), spinal stenosis (SpS), or degenerative spondylolisthesis (DS). Methods: We compared values for EQ-5D (York weights), HUI (Mark 2 and 3), SF-6D, and the SF-36-derived estimate of the Quality of Well Being (eQWB) score using signed rank tests. We tested ...

      IMPORTANCE: False-positive mammograms, a common occurrence in breast cancer screening programs, represent a potential screening harm that is currently being evaluated by the US Preventive Services Task Force.

      OBJECTIVE: To measure the effect of false-positive mammograms on quality of life by measuring personal anxiety, health utility, and attitudes toward future screening.

      DESIGN, SETTING, AND PARTICIPANTS: The Digital Mammographic Imaging Screening Trial (DMIST) quality-of-life substudy ...

      STUDY DESIGN: Spine Patient Outcomes Research Trial observational and randomized cohort participants with a confirmed diagnosis of intervertebral disc herniation (IDH) who received either usual nonoperative care and/or standard open discectomy were followed from baseline at 6 weeks, 3, 6, 12, and 24 months at 13 spine clinics in 11 US states.

      STUDY DESIGN: Cost-effectiveness analysis of a randomized plus observational cohort trial.

      OBJECTIVE: Analyze cost-effectiveness of Spine Patient Outcomes Research Trial data over 4 years comparing surgery with nonoperative care for three common diagnoses: spinal stenosis (SPS), degenerative spondylolisthesis (DS), and intervertebral disc herniation (IDH).

      SUMMARY OF BACKGROUND DATA: Spine surgery rates continue to rise in the United States, but the safety and economic value of these ...

      PURPOSE: To describe measures of mammography performance in a geographically defined population and evaluate the interpreter's use of the Breast Imaging Reporting and Data System (BI-RADS).

      MATERIALS AND METHODS: Mammographic data from 47,651 screening and 6,152 diagnostic examinations from November 1, 1996, to October 31, 1997, were linked to 1,572 pathologic results. Mammographic outcomes were based on BI-RADS assessments and recommendations reported by the interpreting radiologist. ...

      BACKGROUND: In the treatment of distal radial fractures, physicians often advocate internal fixation over cast treatment for potentially unstable fracture patterns, citing the difficulties of successful nonoperative treatment and a decrease in patient tolerance for functional deficiencies. This study was performed to evaluate whether early internal fixation or nonoperative treatment would be preferred for displaced, potentially unstable distal radial fractures that initially had an ...

      OBJECTIVE: Percutaneous access to the stomach can be achieved by endoscopic or fluoroscopic methods. Our objective was to compare indications, complications, efficacy and outcomes of these two techniques.

      METHODS: Records of 370 patients with feeding tubes placed either endoscopically by gastroenterology, or fluoroscopically by radiology, at our university-based tertiary care center over a 54-month period were reviewed.

      RESULTS: 177 gastrostomies were placed endoscopically and 193 ...
