BACKGROUND No firm data are available on the natural history of idiopathic thrombocytopenic purpura (ITP) or on mortality rates or frequency of major bleeding episodes associated with this condition. The disease is thought to have a relatively benign course, despite the frequent occurrence of very low platelet counts. This prevailing conception often guides(More)
OBJECTIVE To evaluate the relations between perceived cognitive function and objective cognitive deficit and to assess variables affecting perceived cognitive function among multiple sclerosis (MS) patients. METHODS A cross sectional study of patients with MS. All patients were interviewed and the Expanded Disability Status Scale (EDSS) score was(More)
The purpose of this study was to identify factors associated with 30-day mortality after coronary artery bypass graft surgery (CABG) among diabetic patients, and to compare them with risk factors among nondiabetics. A subanalysis of a prospective national cohort study was performed which included patients who underwent CABG in 14 medical centers in Israel(More)
The purpose of this study is to investigate the variations in quality of life (QOL) among patients with end-stage renal disease (ESRD) who are receiving replacement therapy in several dialysis centers. This observational study includes interviews with nurses and data extraction from medical charts for all 680 adults who had been on dialysis therapy for more(More)
PURPOSE The impact of prostatectomy on quality of life was assessed in patients with benign prostatic hypertrophy (BPH) who were classified according to the expected benefit from surgical intervention. The relative impact of the 2 surgical techniques (open versus closed) on short-term quality of life was compared. MATERIALS AND METHODS An observational(More)
Kurtzke's EDSS remains the most widely-used measure for clinical evaluation of MS patients. However, several studies have demonstrated the limited reliability of this tool. We introduce a computerized instrument, MS-CANE (Multiple Sclerosis Computer-Aided Neurological Examination), for clinical evaluation and follow up of patients with multiple sclerosis(More)
BACKGROUND Investigation of observed differences in outcomes among medical centers is of major interest to the medical community and the public and has a substantial impact on efforts to improve the quality of medical care. METHODS This study analyzed data from consecutive patients who underwent isolated coronary artery bypass grafting at 14 medical(More)
Predictive models have been used to identify factors that may prolong hospital length of stay (LOS). However, because predictors of LOS are collinear, the proportion of variance associated with each factor in a multivariate stepwise regression model may not reflect its mathematical contribution in explaining LOS. In an attempt to model factor contribution(More)
Information is lacking about the public's perception of the term health-related quality of life (HRQL). Specifically, what are the relations between the domains included in the operational definition of HRQL tools and global health ratings. The purpose of this analysis was to identify factors associated with global rating of HRQL. We conducted a survey of a(More)
OBJECTIVE To assess the appropriateness of using coronary angiography in two major medical centers in Israel. METHODS (a) Development of dichotomous appropriateness rating by concensus of an expert panel for possible indications to use coronary angiography; (b) applying the panel's rating to clinical data gathered from interviews and records of 499(More)
