Genetic nurse counsellors can be an acceptable and cost-effective alternative to clinical geneticists for breast cancer risk genetic counselling. Evidence from two parallel randomised controlled equivalence trials

The Effect of the Breast Cancer Risk Reduction Program on Women With High Breast Cancer Risk in Terms of Their Participation in Screening and Their Health Beliefs and Behavior: A Study Protocol for a Randomized Controlled Trial

BACKGROUND

First-degree biological relatives of individuals with breast cancer have a higher risk of breast cancer.

OBJECTIVE

The purpose of this study was to create a protocol for evaluating the effect of the Breast Cancer Risk Reduction Program (BrCaRRP) on the participation of women at risk in screening and on their health beliefs and risk reduction behaviors.

METHODS

The research was planned as a single-site, single-blind randomized controlled experimental study with a parallel group. Participants will be assigned to intervention and control groups using the Stratified Permuted Block Randomization method. The BrCaRRP will be applied to the intervention group within the theoretical framework of the Health Belief Model and the Health Promotion Model. The BrCaRRP is a 12-week program that encompasses 6 meetings, the first being face-to-face and the others via phone. Multidisciplinary experts calculated the content validity index of BrCaRRP as being 0.954 (high); its weighted kappa statistic is 0.70 (high).

RESULTS

The difference in the likelihood of participation in breast cancer screening between the BrCaRRP and control groups will be evaluated after the interventions. Findings will be presented in terms of our hypotheses.

CONCLUSIONS

The BrCaRRP is a nurse-led program based on the Health Belief Model and the Health Promotion Model. The BrCaRRP has high content validity and interrater reliability.

IMPLICATIONS FOR PRACTICE

This protocol can be tested as an intervention in a randomized controlled study.

Mapping inter-professional collaboration in oncogenetics: Results from a scoping review

Inter-professional collaboration could improve timely access and quality of oncogenetic services. Here, we present the results of a scoping review conducted to systematically identify collaborative models available, unpack the nature and extent of collaboration proposed, synthesize evidence on their implementation and evaluation, and identify areas where additional research is needed. A comprehensive search was conducted in four journal indexing databases on June 13th, 2022, and complemented with searches of the grey literature and citations. Screening was conducted by two independent reviewers. Eligible documents included those describing either the theory of change, planning, implementation and/or evaluation of collaborative oncogenetic models. 165 publications were identified, describing 136 unique interventions/studies on oncogenetic models with somewhat overlapping collaborative features. Collaboration appears to be mostly inter-professional in nature, often taking place during risk assessment and pre-testing genetic counseling. Yet, most publications provide very limited information on their collaborative features, and only a few studies have set out to formally evaluate them. Better quality research is needed to comprehensively examine and make conclusions regarding the value of collaboration in this oncogenetics. We propose a definition, logic model, and typology of collaborative oncogenetic models to strengthen future planning, implementation, and evaluation in this field.

Cost-effectiveness of bringing a nurse into an Italian genetic day clinic: a before and after study

BACKGROUND

Only a few studies explore the role of nurses in genetic counselling and genetic health care, and none of them is related to orphan diseases. In addition, few studies address the issue of finding variables that might affect the economy of a service or perform a cost-effectiveness analysis of a having genetic nurse at a unit.

METHODS

A multidisciplinary panel of experts working in the hospital was set up to identify sensitive indicators and remove confounding variables. This panel evaluated efficiency and effectiveness indicators and drafted a questionnaire to estimate patient perception of the quality of the service. Data were captured from different sources, including the hospital patient database and a web-accessible platform for data collection. More than 600 clinical evaluations of 400 patients were considered, and economic parameters were studied by applying Porter's Time-Driven Activity-Based Costing methodology to evaluate costs and outcomes. Additionally, an anonymous, semi-structured, paper-and-pencil interview questionnaire was given to patients at their periodic follow-ups.

RESULTS

The results showed an increase in the quality of patient management, more accurate data capturing, and higher quality ambulatory care. In fact, approximately 70% of the respondents reported positive changes. In addition, a parallel economic analysis explored indicators influencing economic impact, and outcomes showed positive results with the quality of outcomes improving more compared to the increase in costs.

CONCLUSIONS

The variety of evaluated issues highlighted that having a nurse in a genetic service and at day clinic activities resulted in better access, better scheduling, more satisfaction, and proved to be a cost-effective solution for patients affected by rare diseases.

The effects of decision aids for genetic counselling among people considering genetic testing: A systematic review

AIM

To assess the effectiveness of decision aids for genetic counsellees to improve their conflicts in decision-making and psychological well-being when considering genetic tests for inherited genetic diseases, and their knowledge about these tests and their genetic risks.

DESIGN

Systematic review.

DATA SOURCES

Six electronic databases (PubMed, MEDLINE, OVID Nursing, APA PsycINFO, EMBASE and CINAHL) were searched from inception to May 2022.

REVIEW METHODS

Only randomised controlled trials that examined the effect of decision aids for information provision centring genetic testing on outcomes including decisional conflicts, informed choice making, knowledge on genetic risks or genetic tests, and psychological outcomes among participants who had undergone genetic counselling were included. Their risk of bias was assessed using the Version 2 of the Cochrane risk of bias tool for randomised trials. Results were presented narratively. The review was conducted according to the PRISMA checklist.

RESULTS

Eight included studies examined the effect of booklet-based, computer-based, film-based or web-based decision aids on individuals considering genetic testing for their increased cancer risks. Despite contrasting findings across studies, they showed that decision aids enable genetic counsellees to feel more informed in decision-making on genetic tests, although most showed no effect on decisional conflict. Knowledge of genetic counsellees on genetic risks and genetic tests were increased after the use of decision aids. Most studies showed no significant effect on any psychological outcomes assessed.

CONCLUSIONS

Review findings corroborate the use of decision aids to enhance the effective delivery of genetic counselling, enabling genetic counsellees to gain more knowledge of genetic tests and feel more informed in making decisions to have these tests.

RELEVANCE TO CLINICAL PRACTICE

Decision aids can be used to support nurse-led genetic counselling for better knowledge acquisition and decision-making among counsellees.

A comparative cost analysis of two screening strategies for colorectal cancer in Lynch Syndrome in a South African tertiary hospital

AIM

Lynch Syndrome (LS) individuals have a 25-75% lifetime risk of developing colorectal cancer. Colonoscopy screening decreases this risk. This study compared the cost of Strategy 1: screening colonoscopy for 1st degree relatives of patients that met the Revised Bethesda Criteria (i.e., probands) to Strategy 2: screening colonoscopy for 1^st degree relatives of probands with genetic mutations for Lynch Syndrome based in a resource-constrained health care system.

METHOD

A comparative, health care provider perspective, cost analysis was conducted at a tertiary hospital, using a micro-costing, ingredient approach. Forty probands that underwent genetic testing between November 01, 2014 and October 30, 2015 and their first-degree relatives were costed according to Strategy 1 and Strategy 2. Unit costs of colonoscopy and genetic testing were estimated and used to calculate and compare the total costs per strategy in South African rand (R) converted to UK pounds (£). Sensitivity analyses were performed on colonoscopy adherence, relatives' positivity, and variable discount rates.

RESULTS

The cost for Strategy 1 amounted to £653 344/R6 161 035 compared to £49 327/R 465 155 for Strategy 2 (Discount rate 3%; Adherence 75%; and Positivity rate of relatives 45%). Base case analysis indicated a difference of 92% less in the total cost for Strategy 2 compared to Strategy 1. Sensitivity analyses showed that the difference in cost between the two strategies was not sensitive to variations in adherence, positivity or discount rates.

CONCLUSION

Colonoscopy screening for LS and at-risk family members was tenfold less costly when combined with genetic analysis. The logistics of rolling out this strategy nationally should be investigated.

Women's preferences, willingness-to-pay, and predicted uptake for single-nucleotide polymorphism gene testing to guide personalized breast cancer screening strategies: a discrete choice experiment

BACKGROUND

Single-nucleotide polymorphism (SNP) gene test is a potential tool for improving the accuracy of breast cancer risk prediction. We seek to measure women's preferences and marginal willingness-to-pay (mWTP) for this new technology.

MATERIALS AND METHODS

We administered a discrete choice experiment (DCE) to English-speaking Singaporean women aged 40-69 years without any history of breast cancer, enrolled via door-to-door recruitment with quota sampling by age and ethnicity. DCE attributes comprise: 1) sample type (buccal swab and dried blood spot), 2) person conducting pretest discussion (specialist doctor, non-specialist doctor, and nurse educator), 3) test location (private family clinic, public primary-care clinic, and hospital), and 4) out-of-pocket cost (S$50, S$175, and S$300). Mixed logit model was used to estimate the effect of attribute levels on women's preferences and mWTP. Interactions between significant attributes and respondent characteristics were investigated. Predicted uptake rates for various gene testing scenarios were studied.

RESULTS

A total of 300 women aged 52.6±7.6 years completed the survey (100 Chinese, Malay, and Indian women, respectively). Sample type (P=0.046), person conducting pretest discussion, and out-of-pocket cost (P<0.001) are significantly associated with going for SNP gene testing. Women with higher income and education levels are more willing to pay higher prices for the test. Preferences in terms of mWTP across ethnic groups appear similar, but Chinese women have greater preference heterogeneity for the attributes. Predicted uptake for a feasible scenario consisting of buccal swab, pretest discussion with nurse educator at the hospital costing S$50 is 60.5%. Only 3.3% of women always opted out of the SNP gene test in real life. Reasons include high cost, poor awareness, and indifference toward test results.

CONCLUSION

SNP gene testing may be tailored according to individual preferences to encourage uptake. Future research should focus on outcomes and cost-effectiveness of personalized breast cancer screening using SNP gene testing.

Evidence for models of diagnostic service provision in the community: literature mapping exercise and focused rapid reviews

Background

Current NHS policy favours the expansion of diagnostic testing services in community and primary care settings.

Objectives

Our objectives were to identify current models of community diagnostic services in the UK and internationally and to assess the evidence for quality, safety and clinical effectiveness of such services. We were also interested in whether or not there is any evidence to support a broader range of diagnostic tests being provided in the community.

Review methods

We performed an initial broad literature mapping exercise to assess the quantity and nature of the published research evidence. The results were used to inform selection of three areas for investigation in more detail. We chose to perform focused reviews on logistics of diagnostic modalities in primary care (because the relevant issues differ widely between different types of test); diagnostic ultrasound (a key diagnostic technology affected by developments in equipment); and a diagnostic pathway (assessment of breathlessness) typically delivered wholly or partly in primary care/community settings. Databases and other sources searched, and search dates, were decided individually for each review. Quantitative and qualitative systematic reviews and primary studies of any design were eligible for inclusion.

Results

We identified seven main models of service that are delivered in primary care/community settings and in most cases with the possible involvement of community/primary care staff. Not all of these models are relevant to all types of diagnostic test. Overall, the evidence base for community- and primary care-based diagnostic services was limited, with very few controlled studies comparing different models of service. We found evidence from different settings that these services can reduce referrals to secondary care and allow more patients to be managed in primary care, but the quality of the research was generally poor. Evidence on the quality (including diagnostic accuracy and appropriateness of test ordering) and safety of such services was mixed.

Conclusions

In the absence of clear evidence of superior clinical effectiveness and cost-effectiveness, the expansion of community-based services appears to be driven by other factors. These include policies to encourage moving services out of hospitals; the promise of reduced waiting times for diagnosis; the availability of a wider range of suitable tests and/or cheaper, more user-friendly equipment; and the ability of commercial providers to bid for NHS contracts. However, service development also faces a number of barriers, including issues related to staffing, training, governance and quality control.

Limitations

We have not attempted to cover all types of diagnostic technology in equal depth. Time and staff resources constrained our ability to carry out review processes in duplicate. Research in this field is limited by the difficulty of obtaining, from publicly available sources, up-to-date information about what models of service are commissioned, where and from which providers.

Future work

There is a need for research to compare the outcomes of different service models using robust study designs. Comparisons of ‘true’ community-based services with secondary care-based open-access services and rapid access clinics would be particularly valuable. There are specific needs for economic evaluations and for studies that incorporate effects on the wider health system. There appears to be no easy way of identifying what services are being commissioned from whom and keeping up with local evaluations of new services, suggesting a need to improve the availability of information in this area.

A cost analysis of a cancer genetic service model in the UK

Technological advances in DNA sequencing have made gene testing fast and more affordable. Evidence of effectiveness and cost-effectiveness of genetic service models is essential for the successful translation of sequencing improvements for patient benefit, but remain sparse in the genetics literature. In particular, there is a lack of detailed cost data related to genetic services. A detailed micro-costing of 28 possible pathways relating to breast and/or ovarian cancer and BRCA testing was carried out by defining service activities and establishing associated costs. These data were combined with patient-level data from a Royal Marsden Cancer Genetics Service audit over a 6-month period during which BRCA testing was offered to individuals at ≥10 % risk of having a mutation, in line with current NICE guidance. The average cost across all patient pathways was £2227.39 (range £376.51 to £13,553.10). The average cost per pathway for an affected person was £1897.75 compared to £2410.53 for an unaffected person. Of the women seen in the Cancer Genetics Service during the audit, 38 % were affected with breast and/or ovarian cancer, and 62 % were unaffected but concerned about their family history. The most efficient service strategy is to identify unaffected relatives from an affected individual with an identified BRCA mutation. Implementation of this strategy would require more comprehensive testing of all eligible cancer patients, which could be achieved by integrating BRCA testing into oncology services. Such integration would be also more time-efficient and deliver greater equity of access to BRCA testing than the standard service model.

Interventions to improve patient access to and utilisation of genetic and genomic counselling services

This is the protocol for a review and there is no abstract. The objectives are as follows.

PRIMARY OBJECTIVE

The primary objective is to assess the effectiveness of interventions to improve patient identification, access to and utilisation of genetic and genomic counselling services when compared to: No intervention;Usual or current practice; andOther active intervention.

SECONDARY OBJECTIVE

The secondary objective is to explore the resource use and costs associated with interventions aimed at improving patient identification, access to and utilisation of genetic and genomic counselling services from studies meeting the eligibility criteria. We will report on factors that may explain variation in the effectiveness of interventions aimed at improving patient identification, access to and utilisation of genetic and genomic counselling services from studies meeting the eligibility criteria. Another secondary objective is to explore how interventions which target improved patient identification, access to and utilisation of genetic and genomic counselling services affect the subsequent appropriate use of health services for the prevention or early detection of disease. It is also possible that the genetic counselling interaction itself will contribute to the possible use of preventative services.

[Comparative effectiveness and safety of screening and counselling interventions conducted by non-physicians and physicians: a systematic review]

BACKGROUND

Current forecasts project a future shortage of physicians which might compromise the quality of health care if not addressed adequately by health policy decisions. One proposed measure is to shift selected tasks and responsibilities from physicians to other medical staff, a strategy that has proven successful in some areas (e. g., chronic disease management). To date, no studies have systematically and objectively assessed whether the application of a similar strategy to screening and counselling in preventive medicine compromises patients' health outcomes and experiences.

METHODS

A systematic search was conducted in MEDLINE, the Cochrane Library, CINAHL, and EMBASE (January 2000 - June 2014). We dually reviewed articles and assessed the risk of bias.

RESULTS

3,315 citations were identified and five relevant articles located. Overall, the available evidence indicated that there were no substantial differences in benefits and harms of screening (colon cancer screening, sexual transmitted diseases, and mammography) and counselling (genetic breast cancer risk) between non-physicians and physicians. The quality of evidence, however, is very low for most comparisons. Reported statistically significant differences for some outcomes need to be viewed cautiously.

CONCLUSION

Shifting tasks from physicians to other medical staff for screening and counselling could be a viable strategy to address the shortage of practicing physicians. Adequate training by a physician, however, is a prerequisite for the safe and beneficial screening and counselling conducted by non-physicians.

Valuing the economic benefits of complex interventions: when maximising health is not sufficient

Complex interventions, involving interlinked packages of care, challenge the application of current methods of economic evaluation that focus on measuring only health gain. Complex interventions may be problematic on two levels. The complexity means the intervention may not fit into one of the current appraisal systems, and/or maximising health is not the only objective. This paper discusses the implications of a programme of work that focused on clinical genetics services, as an example of a complex intervention, and aimed to identify the following: the attributes that comprise both health and non-health aspects of benefits and whether it is possible to evaluate such an intervention using current National Institute for Health and Clinical Excellence appraisal processes. Genetic services and tests are a good example of a complex intervention and have broader objectives than just health gain, which may usefully be measured using the concept related to capability, which we have called 'empowerment'. Further methodological work is required to identify the trade-off between non-health (empowerment) and health benefits for other complex interventions. We do not advocate a move away from QALY maximisation but do suggest that there is a need for a more considered approach that can take account of the perceived value for non-health attributes for some complex interventions.

A study of the practice of individual genetic counsellors and genetic nurses in Europe

Advances in genetics have meant that the genetic services are now accessed by increasing numbers of patients. One way of dealing with the pressure on services without jeopardising patient care is the inclusion of nonmedical genetic counsellors and genetic nurses in the genetic services team. However, a cohesive approach to the profession has been lacking in Europe, and an educational programme and registration system for European practitioners is required. The aim of this study was to ascertain the type of work undertaken by genetic nurses and counsellors in Europe and the context in which they practised. We used a cross-sectional survey design to collect data from 213 practitioners, either genetic nurses or genetic counsellors, from 18 European countries. Respondents completed the survey online, and data were analysed using descriptive statistics and cross-tabulations. The majority were involved in undertaking the initial contact with the patient (89.9 %) and explaining the genetic test to the patient (91.5 %), while 74 % ordered tests and 91.4 % obtained informed consent for such tests. Psychological support before and after genetic testing was provided by 80.2 % of respondents, and 82.1 % reported regularly managing cases autonomously. While the genetic counselling profession is barely established in some countries, counsellors are able to contribute substantially to patient care as part of the multi-disciplinary team. Further efforts to establish the profession at the European level through a registration process will enhance the confidence in this new group of allied health professionals.

Cancer genetic risk assessment for individuals at risk of familial breast cancer

BACKGROUND

The recognition of an inherited component to breast cancer has led to an increase in demand for information, reassurance, and genetic testing, which has resulted in the creation of genetic clinics for familial cancer. The first step for patients referred to a cancer genetic clinic is a risk assessment.

OBJECTIVES

To evaluate the impact of cancer genetic risk-assessment services on patients at risk of familial breast cancer.

SEARCH METHODS

The specialised register maintained by the Cochrane Breast Cancer Group was searched on 16th February 2005. We also searched MEDLINE, EMBASE, CINAHL, PsycLIT, CENTRAL, DARE, ASSIA, Web of Science, SIGLE and LILACS. The original searches covered the period 1985 to February 2005. We also handsearched relevant journals. For this review update the search was repeated through to April 2011.

SELECTION CRITERIA

We considered trials looking at interventions for cancer genetic risk-assessment services for familial breast cancer for inclusion. Trials assessed outcomes such as understanding of risk, satisfaction and psychological well-being. We excluded studies if they concerned cancers other than breast cancer or if participants were not at risk of inherited breast cancer. We also excluded trials concerning the provision of general cancer genetic information or education as this review was concerned with the delivery of genetic risk assessment. Participants could be individuals of any age or gender, with or without a known BRCA mutation, but without a previous history of breast cancer or any other serious illness.

DATA COLLECTION AND ANALYSIS

Two review authors independently assessed trial quality and extracted data. Additional information was sought from investigators as necessary. Due to the heterogeneity of both the interventions and outcomes, we reported data descriptively.

MAIN RESULTS

In this review update, we included five new trials, bringing the total number of included studies to eight. The included trials (pertaining to 10 papers), provided data on 1973 participants and assessed the impact of cancer genetic risk assessment on outcomes including perceived risk of inherited cancer, and psychological distress. This review suggests that cancer genetic risk-assessment services help to reduce distress, improve the accuracy of the perceived risk of breast cancer, and increase knowledge about breast cancer and genetics. The health professional delivering the risk assessment does not appear to have a significant impact on these outcomes.

AUTHORS' CONCLUSIONS

This review found favourable outcomes for patients after risk assessment for familial breast cancer. However, there were too few papers to make any significant conclusions about how best to deliver cancer genetic risk-assessment services. Further research is needed assessing the best means of delivering cancer risk assessment, by different health professionals, in different ways and in alternative locations.

Incremental cost of non-invasive prenatal diagnosis versus invasive prenatal diagnosis of fetal sex in England

OBJECTIVES

Fetal sex determination is performed for women who carry X-linked conditions, for example Duchenne muscular dystrophy (DMD), or those associated with ambiguous genitalia, for example congenital adrenal hyperplasia (CAH). Non-invasive prenatal diagnosis (NIPD) using cell-free fetal DNA (cffDNA) in maternal plasma is an alternative to invasive prenatal diagnosis (IPD), which carries a 1% risk of miscarriage. This study aimed to evaluate the incremental cost of NIPD compared with IPD of fetal sex.

METHODS

Diagnostic accuracy, invasive testing rate, and pregnancy outcome following NIPD were ascertained from an audit of all cases referred to two laboratories in 2006 to 2009. Care pathways for DMD and CAH were established and key cost drivers for IPD and NIPD identified using costs derived from published estimates and local laboratory values.

RESULTS

The differences in mean costs per pregnancy for NIPD versus IPD were small for DMD [mean difference - £87, 95% confidence interval (CI) - £303 to £131] and CAH (-£193, 95% CI - £301 to - £84). Testing costs associated with NIPD were offset by fewer women requiring invasive testing.

CONCLUSIONS

The costs of NIPD and IPD of fetal sex are similar. NIPD can provide benefits for many women by avoiding the risks of invasive testing, without incurring additional costs.

Task shifting in maternal and newborn care: a non-inferiority study examining delegation of antenatal counseling to lay nurse aides supported by job aids in Benin

Background

Shifting the role of counseling to less skilled workers may improve efficiency and coverage of health services, but evidence is needed on the impact of substitution on quality of care. This research explored the influence of delegating maternal and newborn counseling responsibilities to clinic-based lay nurse aides on the quality of counseling provided as part of a task shifting initiative to expand their role.

Methods

Nurse-midwives and lay nurse aides in seven public maternities were trained to use job aids to improve counseling in maternal and newborn care. Quality of counseling and maternal knowledge were assessed using direct observation of antenatal consultations and patient exit interviews. Both provider types were interviewed to examine perceptions regarding the task shift. To compare provider performance levels, non-inferiority analyses were conducted where non-inferiority was demonstrated if the lower confidence limit of the performance difference did not exceed a margin of 10 percentage points.

Results

Mean percent of recommended messages provided by lay nurse aides was non-inferior to counseling by nurse-midwives in adjusted analyses for birth preparedness (β = -0.0, 95% CI: -9.0, 9.1), danger sign recognition (β = 4.7, 95% CI: -5.1, 14.6), and clean delivery (β = 1.4, 95% CI: -9.4, 12.3). Lay nurse aides demonstrated superior performance for communication on general prenatal care (β = 15.7, 95% CI: 7.0, 24.4), although non-inferiority was not achieved for newborn care counseling (β = -7.3, 95% CI: -23.1, 8.4). The proportion of women with correct knowledge was significantly higher among those counseled by lay nurse aides as compared to nurse-midwives in general prenatal care (β = 23.8, 95% CI: 15.7, 32.0), birth preparedness (β = 12.7, 95% CI: 5.2, 20.1), and danger sign recognition (β = 8.6, 95% CI: 3.3, 13.9). Both cadres had positive opinions regarding task shifting, although several preferred 'task sharing' over full delegation.

Conclusions

Lay nurse aides can provide effective antenatal counseling in maternal and newborn care in facility-based settings, provided they receive adequate training and support. Efforts are needed to improve management of human resources to ensure that effective mechanisms for regulating and financing task shifting are sustained.

Evaluation of group genetic counseling for hereditary breast and ovarian cancer

As demand for genetic counseling regarding hereditary cancer continues to grow, more efficient methods of providing this service must be explored. In this pilot study, group genetic counseling was offered to two different cohorts of women seeking genetic counseling for Hereditary Breast and Ovarian Cancer. Seven group sessions, designed to cover all aspects of an individual genetic counseling appointment, were conducted. Although patients were receptive to group genetic counseling, a significant proportion chose individual counseling when given the option. Advantages of group genetic counseling include shared experience and increased efficiency. Disadvantages include increased frustration at not being eligible for genetic testing, group influence on decision-making, privacy concerns, increased need for follow-up, and difficulty booking group appointments. Overall, the level of patient satisfaction with group genetic counseling was similar to that of individual counseling. The results of this pilot study suggest that further research is needed to determine whether group genetic counseling is an acceptable alternative to individual counseling.

Patient preferences and National Health Service costs: a cost-consequences analysis of cancer genetic services

The study has three aims; firstly to establish if, having been informed of their risk status and that gene testing is inappropriate for them, low and moderate risk patients have misunderstood or failed to grasp this and want a test that is inappropriate for them. Secondly, to elicit patients' willingness to pay for cancer genetic services. Thirdly, to ascertain the aspects of cancer genetics services that are important to high risk patients and present service configurations prioritised in terms of preferences accompanied by their costs (cost-consequences analysis). Patient preferences were gathered from 120 patients returning a self-administered discrete choice questionnaire issued post genetic risk assessment. Patients at low and moderate risk of developing breast cancer desired inappropriate testing. Patients at high, moderate and low risk of developing genetic cancer were willing to pay up to 3,000 pounds for genetic serviced, which exceeds the current estimated cost of providing testing and counselling. Counselling by a genetics associate accompanied by favourable levels of other attributes provided high utility and substantial cost savings.

EuroGentest: DNA-based testing for heritable disorders in Europe

OBJECTIVES

Regarding the recent attention to develop policies regarding the provision of clinical genetic testing services, access to, acceptance, utilisation and regulation of genetic services was investigated in selected European countries as well as one non-European country.

METHODS

Data were collected on the basis of relevant international reports and sources accessible via the internet, from self- designed, internationally administered surveys and with the help of a panel of experts from European countries participating in several workshops as well as from National European Societies of Human Genetics.

RESULTS

A selection of divergent health care systems was reviewed and compared (e.g. Finland, Germany, Portugal, Sweden, UK, France, Italy, Spain, Czech Republic, Lithuania and Serbia/Montenegro). For the evaluation of clinical validity and utility of genetic testing, background information was provided focussing on DNA-based testing for heritable disorders with a strong genetic component (usually due to the action of a single gene).

CONCLUSIONS

There is great heterogeneity in genetic testing services among the countries surveyed. It is premature to mandate that genetic testing provided by clinical services meets professional standards regarding clinical validity and utility, because there is to date no consensus within the scientific community and among health care providers to what extent clinical validity and utility can and need to be assessed. Points to consider in the process of developing such standards are proposed.

Risk estimation for familial breast cancer: improving the system of counselling

Women with a family history of breast cancer dominate referrals for cancer genetic risk counselling across Europe. Given limited health care resources, managing this demand, while achieving good value for money for health services, is a major challenge. The paper reports the benefits and associated costs of moving from a traditional system of deriving family history of cancer during the patient's initial clinic attendance, to a protocol-driven system with pre-counselling assessment of family history. The evaluation was based on retrospective clinical data and a clinical audit. Changes in risk between referral and final risk assessment were ascertained and the cost difference between the two systems estimated. The study results showed that 14% of women assessed as 'low' genetic risk at referral were reassessed as 'moderate' or 'high' genetic risk for breast cancer following verification of family history. Sixteen per cent of those assessed as 'moderate' or 'high' genetic risk at referral were reassessed as 'low' genetic risk for breast cancer. Compared to the traditional system, the new protocol-driven system of risk assessment was more consistent, which reduced the number of return appointments and created time for clinicians to spend with other patients. The estimated cost of family history verification and genetic clinic appointment was calculated as 91.68 pounds (132.53 euro) per family history, compared to 104.00 pounds (150.34 euro) for the traditional system, representing a slight reduction in health service costs. Finally, the protocol-driven system can be used as part of ongoing audit for planning future genetics services in Scotland.

Nurse-led cancer genetics clinics in primary and secondary care in varied ethnic population areas: interaction with primary care to improve ascertainment of individuals from ethnic minorities

Genetic services are receiving increasing numbers of referrals of people with a family history of cancer for assessment of genetic risk, and therefore need to find cost-effective ways of meeting this rising demand. General Practitioners (GPs) are known to be reluctant to take on genetic consultations. Current evidence suggests that black and ethnic minorities are poorly represented in cancer genetics clinics. Nurse-led clinics in primary care have been found to be successful. This paper reports a pilot study to test the feasibility, accessibility, and effectiveness of providing cancer genetics nurse-counsellor clinics in primary and secondary care in the SW Thames Region. We initially set up three nurse-led clinics in general practices and two in district hospitals with very different ethnic catchment areas. The service was advertised by displaying posters and leaflets, translated into different languages. Self-referrals were encouraged. We set up a user involvement sub-group and held two focus group meetings to assess barriers to, and satisfaction with, the service. A patient satisfaction questionnaire was designed and administered after the appointments. We also designed a GP satisfaction survey regarding the service. Data on referrals, including their source and outcome, were recorded on a purpose-designed study database. We received increasing numbers of referrals to all clinics over the course of the pilot. Of 137 referrals, 23 (17%) were from ethnic minorities, of whom 17/23 (74%) were self-referred, compared with 102 British White referrals, of whom 91/102 (89%) were self-referred. Sixty-two patients (45%) were assessed to be at population risk and reassured, 60 (44%) were at moderate risk, and 15 (11%) were at high risk and were referred on for appropriate management. These proportions were similar for black and ethnic minority patients. Most patients reported high satisfaction with the service.
