BACKGROUND Thorough skin self-examination (TSSE) has substantial potential to reduce melanoma mortality by early detection. METHODS We interviewed 2,126 patients before a scheduled routine visit with a primary care physician, at which participation in a randomized trial was offered as part of the Check-It-Out Project. We asked about skin examination(More)
OBJECTIVES Cost-utility analysis of screening for anal cancer in high-risk groups from a UK perspective. METHODS Criteria for the assessment of screening programmes were combined in a Markov model representing the natural history of anal cancer and HIV infection in the UK population of men who have sex with men (MSM). Alternative screening programmes were(More)
BACKGROUND Age-related macular degeneration (AMD) is a leading cause of visual impairment and blindness. It is likely that treatment of AMD at earlier stages is more effective than later treatment; thus, screening for AMD should be considered. The aim of this study was to develop a natural history model of AMD to estimate the cost-effectiveness of(More)
In this study the authors developed and explored measures of short-term variations in accuracy on a test of sustained attention, a departure from traditional measures of average performance over long periods. The study participants were normal young adults, actively engaged in a continuous performance test (CPT). Both correct (hits) and incorrect (misses)(More)
BACKGROUND Melanoma and obesity have both increased in recent years. Given the propensity of body dissatisfaction among the obese, the objectives of this paper were to determine how body satisfaction might influence skin examination and to examine differences in this relationship by gender among the participants of Check-It-Out, a study to increase thorough(More)
The mandatory nature of recommendations made by the National Institute for Health and Clinical Excellence (NICE) in the UK has highlighted inherent difficulties in the process of disinvestment in existing technologies to fund NICE-approved technologies. A lack of evidence on candidate technologies means that the process of disinvestment is subject to(More)
OBJECTIVE The aim of this study was to evaluate usability of a prototype tablet PC-administered computerized adaptive test (CAT) of headache impact and patient feedback report, referred to as HEADACHE-CAT. MATERIALS AND METHODS Heuristic evaluation specialists (n = 2) formed a consensus opinion on the application's strengths and areas for improvement(More)
Attempts to sustain a narrow focus of attention over a long period of time are effortful and are punctuated by lapses. Most studies of sustained attention performance obscure the presence and pattern oflapses by reporting measures that are summed across the entire period of an individual's performance, or that are average scores for blocks of trials across(More)
