Estimating time and out-of-pocket costs incurred by families attending a pediatric cochlear implant programme.

OBJECTIVES: The objectives of this study are to estimate time and out-of-pocket costs incurred by families attending a pediatric cochlear implant programme. In addition, qualitative data examine the intangible costs faced by families. METHODS: Data was collected during semi-structured face-to-face interviews with parents of children with a cochlear implant attending a clinic visit at Nottingham Cochlear Implantation Programme (NPCIP), UK. Information supplied included socio-demographic characteristics, mode of travel, out-of-pocket expenses, time foregone, and details of companions. Quantitative data was stored and analysed in SPSS version 11.5. RESULTS: Two hundred and sixteen face-to-face interviews were conducted with parents of children implanted for between 1 month and 13 years. Time and out-of-pocket costs were significantly higher for those in the first 2 years of the programme, mean UK pound 3090 per annum compared to UK pound 2159 per annum for those in years >2-5 and UK pound 1815 per annum for those in years >5 (P<0.001). The biggest component of this was time costs, although the sensitivity analysis revealed that these were also most variable depending on the methods used to estimate them. The largest out-of-pocket cost incurred by families was travel costs which accounted for 44%, although 16% of families received some financial help with travel costs. The qualitative findings are consistent with these findings, also showing that over time the financial and intangible costs incurred as a result of cochlear implantation decline. CONCLUSIONS: This study is the first to obtain primary data on the time and out-of-pocket costs incurred by families attending a pediatric cochlear implant programme in the UK. It finds that these costs are greatest for those families in the first 2 years of the programme and/or who live furthest from the programme.

Eliciting relative preferences for two methods of colorectal cancer screening.

Two methods of mass population screening for colorectal cancer - faecal occult blood testing and sigmoidoscopy - have been the subject of randomized controlled trials in the UK. A national screening programme is currently under consideration and the choice of screening method remains open. To be successful, a programme will require high levels of uptake, and uptake is likely to depend upon subjects' attitudes towards the screening method introduced. Although a preferred screening method has already been identified from a questionnaire survey, we undertook a further interview study (n = 106), with a view to comparing the results of two different approaches to eliciting public preferences. In comparison with the questionnaire study, a higher proportion of interview subjects stated a preference. Interview subjects were generally more favourably disposed towards sigmoidoscopy, excepting those with previous experience. Compared with the questionnaire survey, the interviews provided richer information on the reasons for preferences offered. Individual preferences were evidently subjective and dependant on attitudes towards a variety of method characteristics, such as discomfort, convenience and perceived sophistication. Characteristics such as age and low income, which had predicted preferences in the questionnaire study, predicted preferences in the interview study also. The difference between the results obtained by the different elicitation techniques can be explained in terms of the differential provision of information and sample selection. Conclusions made about public preferences are likely to depend on the technique employed in eliciting them.

Willingness-to-pay for pediatric cochlear implantation.

OBJECTIVE: This paper presents the results of the first willingness-to-pay (WTP) study to be undertaken on cochlear implantation. It aims to measure the values parents place on the UK having a pediatric cochlear implantation (PCI) programme. METHODS: Face-to-face semi-structured interviews were conducted with parents of children from the Nottingham Pediatric Cochlear Implant programme, whom had been implanted for a period ranging from 1 month to 13 years. Parents willingness-to-pay for the UK to have a pediatric cochlear implantation programme were elicited using a bidding process question format and via a discrete choice question. To see if income was a significant determinant of willingness-to-pay an analysis of variance (ANOVA) was undertaken in the statistical package SPSS version 10. RESULTS: Two hundred and sixteen parents were interviewed over the period July 2001-August 2002, representing over 130h of interviewing. The mean and median willingness-to-pay values elicited were UK pound 127 and 50 per month, respectively (UK pound 2001/2002). Willingness-to-pay was positively related to income (P<0.020). When the income constraint was removed, 99% of parents choose the implant over having the money the implant would cost to spend in some other way to benefit their child. CONCLUSIONS: Parents of implanted children were willing to pay substantial monthly amounts for pediatric cochlear implantation. Most parents saw no alternative to pediatric cochlear implantation that could improve their child's quality of life to the same extent. Willingness-to-pay was sensitive to income as expected suggesting that the values elicited are both valid and influenced by a respondent's budget constraint.

Innovation and funding specialist services. Cochlear implantation.

This paper traces the innovative development of the Nottingham Cochlear Implant Programmes. The paediatric programme was the first to be established in the UK in 1989 and remains the largest programme in the UK today, whilst the adult programme developed later, in 1994. The first section of the paper describes trends in service development whilst the second section makes detailed reference to the history of funding arrangements which enabled the programme to become established. The third part of the paper examines the (de)merits of locality purchasing versus centralised purchasing for specialist services, using cochlear implantation as way of illustration. The paper aims to provide an informative history of the development of the service in Nottingham and from this background create debate as to the most appropriate future funding mechanism for cochlear implantation in particular and specialist services in general.

Women's interpretation of cervical smear test results.

Screening for cervical cancer using the Papanicolaou smear test has been available in England since the 1960s, yet very little is known about how women interpret their test results. This questionnaire study required women to explain, in their own words, the meaning of normal and abnormal test results. It was discovered that the use of the word cell as a description of findings was extremely common, and that a proportion of subjects equated abnormal results with technical inadequacy. The frequency of circularity in the interpretations, i.e. interpreting 'normal' as 'not abnormal' and vice versa, was striking. Contrary to previous research, we find that, whilst many women interpret normal results as indicating the current absence of cancer, few appear to believe that future cancer is thereby definitively ruled out. By the same token, only a very small minority interpret abnormal results as definitive of cancer.

Colorectal cancer, screening and survival: the influence of socio-economic deprivation.

OBJECTIVES: To determine the extent to which socio-economic deprivation explains colorectal cancer prevalence, subject participation in screening, and postoperative survival and life expectancy. METHODS: Regression analyses of clinical data from a large randomized controlled trial, augmented by geographical-based indices of deprivation. RESULTS: Deprivation appears to exert no significant impact on colorectal cancer prevalence but is a major factor explaining subject participation in screening. Cancer detection at later stages reduces life expectancy at time of treatment. Females from more-deprived areas have poorer post-treatment life expectancies and survival prospects, independently of their screening behaviour. CONCLUSIONS: Screening increases the chances of having a cancer treated at an earlier stage, and treatment at an earlier stage is associated with longer subsequent life expectancy. However, those from more-deprived areas are less likely to accept an invitation to be screened.

Evidence of improving cost-effectiveness of pediatric cochlear implantation.

OBJECTIVES: To examine the cost-effectiveness of pediatric cochlear implantation over time. METHODS: A prospective study based on ninety-eight children implanted between 1989 and 1996 at Nottingham's Paediatric Cochlear Implantation Programme, UK. The influence of outcomes and other variables on total costs was examined using multivariate regression analysis. RESULTS: Having controlled for potential confounding variables, total cost was negatively related to year of implant and positively related to the number of hours of rehabilitation (p=.000). CONCLUSIONS: Having controlled for outcomes (Categories of Auditory Performance and Speech Intelligibility Rating), the cost-effectiveness improved over time. This finding may be due to a learning curve and have policy implications.

Receipt of information and women's attitudes towards ultrasound scanning during pregnancy.

OBJECTIVE: To audit women's receipt of information during routine antenatal ultrasound investigations; and to investigate women's perceptions of, and attitudes towards, routine screening. DESIGN: Analysis of the records of 384 women from in and around Nottingham, UK, who maintained a diary throughout the course of their pregnancies. RESULTS: The mean number of ultrasound scans received by each women during her pregnancy was 2.6, with more than 96% of women receiving at least one scan. Women initially scanned earlier received more scans in total. Women appeared aware of the specific reasons for each scan being undertaken, and only a minority were dissatisfied by the information they had received. The preponderance of information received during the scans related to results and arrangements for subsequent visits, with only 10% of women reporting receiving information about the procedure itself. Most women reported positive feelings towards scanning, and few gave indications that they would prefer changes in the conduct of the procedure. CONCLUSIONS: The great majority of the women in our study were satisfied with their experiences of routine ultrasound scanning, accepting the procedure uncritically.

Communicating mild and borderline abnormal cervical smear results: how and what are women told?

The way in which women are informed about borderline or mild smear results can have a significant psychological impact. By means of a questionnaire survey of general practices in Nottingham, England, this study audited the means by which abnormal smear results were normally communicated to subjects and analysed the content of these communications. Transmitting abnormal smear results, either by letter or by telephone call, was typically the responsibility of the practice nurse, and communications varied widely in informational content. We conclude that the method and content of communications imparting mild or borderline smear results differs between general practices, even within a small geographical area.

Early withdrawal from cervical cancer screening: the question of cost-effectiveness.

In countries such as the UK, mass population screening for cervical cancer has been undertaken since the 1960s. Although of established effectiveness, no formal evaluation of the screening protocol was carried out prior to its implementation. On the basis of a published mathematical modelling exercise, it has been speculated that withdrawing women from the screening programme at an earlier age than at present, whilst leading to a higher rate of invasive cervical cancer (ICC), could reduce resource use. Using estimates of screening and treatment costs, and of expected life-years lost following earlier withdrawal, we simulated cost-effectiveness ratios for various scenarios described by the model. Median cost savings resulting from a life-year lost never exceeded pound10000 for any scenario, although the estimates were particularly sensitive to the assumed age at cancer presentation and the rate of cancer progression. Our findings seem to offer little economic support for the early withdrawal of subjects from the cervical screening programme.

Willingness-to-pay for colorectal cancer screening.

Willingness-to-pay (WTP) techniques are increasingly being used in economic evaluation, as a means of assessing the value of new health care technologies. This paper presents the results of a WTP investigation of two types of screening for colorectal cancer. A questionnaire was issued to a general population via general practitioners (GPs), yielding a sample of approximately 2000 cases for analysis. Regression models demonstrated that WTP was significantly influenced by factors such as gender, income, age, risk perceptions, illness experiences and health beliefs. The median WTP for screening emerged as being pound30 or pound50, depending on the method used to elicit WTP, but independent of the screening protocol. Combining the results with those from related research, it emerged, first, that WTP subjects offered higher values for flexible sigmoidoscopy screening than the costs actually incurred by revealed preference studies and, second, they offered WTP values similar to the likely resource costs of the screening procedures.

Measuring concentration in primary care.

There is evidence that patient choice and the quality of service delivery in primary care can be influenced by the organisation and structure of provision at the local level. However, the formal measurement of structure in primary care has yet to be undertaken. Using data for Coventry, standard concentration measures are estimated, which show that concentration varies considerably across the city and tends to be higher in areas of lower deprivation. Assuming that patient choice is an important consideration in health care planning, concentration measurement may provide a useful tool for health authorities in making decisions about GP numbers, practice mergers and re-location.

Prevention of mother-to-child transmission of HIV in developing countries: recommendations for practice. The Ghent International Working Group on Mother-To-Child Transmission of HIV.

OBJECTIVES: Different approaches to prevent mother-to-child transmission of HIV are being evaluated in developing countries. The first trials using a short regimen of zidovudine have been successful in Thailand, Côte d'Ivoire and Burkina Faso. International and local strategies are now being considered. The Ghent International Working Group on Mother-to-Child Transmission of HIV developed public health policy options to integrate these interventions into basic and maternal and child health (MCH) services. METHODS: The following tasks were undertaken: a critical review of randomized trials; an international pooled analysis of late postnatal transmission of HIV through breastfeeding; a review of the cost-effectiveness and cost-benefit of antiretroviral prophylaxis; a feasibility assessment of preventive strategies, including a postal survey on HIV voluntary counselling and testing (VCT) of pregnant women; the identification of requirements and research priorities for prenatal, obstetric and paediatric care. These projects provided the background for a three-day workshop in Ghent, Belgium, in November 1997. Conclusions were further refined, based on 1998 research findings. RESULTS: A summary of relevant evidence and ten public health recommendations are reported. VCT for pregnant women, a short regimen of zidovudine together with alternatives to breastfeeding currently represent the best option to reduce vertical transmission in most developing countries. The primary goal of the integrated package supporting these interventions is to alleviate overall maternal and infant morbidity and mortality. CONCLUSION: Prevention of mother-to-child transmission of HIV should now be considered for integration into basic health and MCH services of selected countries, with the involvement of governments and donor agencies.

The hospital costs of treating lung cancer in the United Kingdom.

A detailed patient-by-patient costing analysis, based on case records for 253 patients diagnosed in 1993, reveals that the mean 4-year diagnosis and management costs amounted to Pound Sterling 6150 and Pound Sterling 5668 for non-small cell and small cell lung cancer respectively. These costs are lower than those identified in Canadian studies, the difference being explained by the use of a simulated costing methodology in these studies, lower unit costs and less aggressive interventions.
