Int J Technol Assess Health Care
April 2012
Objectives: The aim of this study was to identify and characterize studies that have used quality-adjusted life-years (QALYs) based on measurements of patients' health-related quality of life (HRQoL) as an indicator of effectiveness of screening programs.
Methods: Systematic search of the literature until March 2010, using several electronic databases. Initial screening of articles based on abstracts, and evaluation of full-text articles were done by at least two of the authors.
Background: Expert opinions vary on the appropriate role of antibiotics for sinusitis, one of the most commonly diagnosed conditions among adults in ambulatory care.
Objectives: We examined whether antibiotics are effective in treating acute sinusitis, and if so, which antibiotic classes are the most effective.
Search Strategy: We searched the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library, 2007, Issue 3); MEDLINE (1950 to May 2007) and EMBASE (1974 to June 2007).
Purpose: To assess the cost effectiveness and cost utility of an organized screening programme for glaucoma. The previous cost-effectiveness studies of screening show inconsistent results, and the cost utility of screening has not been assessed.
Methods: An organized screening programme was simulated using Markov modelling in a population aged 50-79 years at 5 year intervals.
Objectives: Despite controversies, endoscopic thoracic sympathectomy (ETS) has been used as a treatment for excessive sweating of hands and face and for facial blushing. This study aims to evaluate the effectiveness of ETS for the current indications in a systematic review.
Methods: Controlled clinical trials and cohort studies with more than 100 patients were included.
