The use of decision-analytic modelling for the purpose of health technology assessment (HTA) has increased dramatically in recent years. Several guidelines for best practice have emerged in the literature; however, there is no agreed standard for what constitutes a 'good model' or how models should be formally assessed. The objective of this paper is to(More)
IVF treatment, which involves ovarian stimulation, poses significant health problems such as ovarian hyperstimulation and is associated with a high incidence of multiple pregnancy and premature birth. In this paper, we demonstrate how natural cycle IVF is an effective and potentially cost-effective alternative treatment option for certain groups of(More)
The study reports a questionnaire survey of female university students intended (1) to delineate their knowledge of cervical cancer and screening, and (2) to impute their valuation of the introduction of human papillomavirus (HPV) testing. It was found that almost 80% of respondents thought cervical cancer was a leading cause of cancer death amongst women.(More)
This paper describes the process of developing and testing a new questionnaire, Process Outcome Specific Measure (POSM), including an assessment of its content validity and reliability. The questionnaire was developed within the context of Trial Of Management of Borderline and Other Low-grade Abnormal smears (TOMBOLA) to assess the psychosocial impact of a(More)
This paper aims to complement existing clinical guidelines by providing evidence of the relative cost-effectiveness of treatments for infertility in the UK. A series of decision-analytical models have been developed to reflect current diagnostic and treatment pathways for the five main causes of infertility. Data to populate the models are derived from a(More)
OBJECTIVES The aim of this study was to estimate the time and travel costs generated by women when attending for Papanicolaou (Pap) smear tests or colposcopy appointments in the United Kingdom, both absolutely and relative to the health service cost of the national cervical cancer screening programs. METHODS Data were obtained from questionnaires(More)
Receipt of an abnormal cervical smear result often generates fear and confusion and can have a negative impact on a woman's well-being. Most previous studies have focussed on high-grade abnormal smears. This study describes the psychological and psychosocial effects, on women, of having received a low-grade abnormal smear result. Over 3500 women recruited(More)
Cervical screening reduces the risk of cervical cancer by detecting and treating cervical intraepithelial neoplasia (CIN). The management of women with low-grade cervical abnormalities is controversial. Two management policies exist: repeat smears in primary care and colposcopy examination. It is not clear which of these is the more effective and efficient.(More)
This study assesses the extent and accuracy of women's knowledge of cervical cancer, risk factors, and the efficacy of the national screening program. Data were obtained from a questionnaire survey of randomly selected women eligible for screening, drawn from a population in east-central England. The majority of women in the sample overestimated the current(More)
The purpose of this study is to explain the rationale for the value of information approach to priority setting for research and to describe the methods intuitively for those familiar with basic decision analytical modeling. A policy-relevant case study is used to show the feasibility of the method and to illustrate the type of output that is generated and(More)
