    BACKGROUND A gap analysis was conducted to determine which areas of breast cancer research, if targeted by researchers and funding bodies, could produce the greatest impact on patients. METHODS Fifty-six Breast Cancer Campaign grant holders and prominent UK breast cancer researchers participated in a gap analysis of current breast cancer research. Before, during and following the meeting, groups in seven key research areas participated in cycles of presentation, literature review and discussion. Summary papers were prepared by each group and collated into this position paper highlighting the research gaps, with recommendations for action. RESULTS Gaps were identified in all seven themes. General barriers to progress were lack of financial and practical resources, and poor collaboration between disciplines. Critical gaps in each theme included: (1) genetics (knowledge of genetic changes, their effects and interactions); (2) initiation of breast cancer (how developmental signalling pathways cause ductal elongation and branching at the cellular level and influence stem cell dynamics, and how their disruption initiates tumour formation); (3) progression of breast cancer (deciphering the intracellular and extracellular regulators of early progression, tumour growth, angiogenesis and metastasis); (4) therapies and targets (understanding who develops advanced disease); (5) disease markers (incorporating intelligent trial design into all studies to ensure new treatments are tested in patient groups stratified using biomarkers); (6) prevention (strategies to prevent oestrogen-receptor negative tumours and the long-term effects of chemoprevention for oestrogen-receptor positive tumours); (7) psychosocial aspects of cancer (the use of appropriate psychosocial interventions, and the personal impact of all stages of the disease among patients from a range of ethnic and demographic backgrounds). CONCLUSION Through recommendations to address these gaps with future research, the long-term benefits to patients will include: better estimation of risk in families with breast cancer and strategies to reduce risk; better prediction of drug response and patient prognosis; improved tailoring of treatments to patient subgroups and development of new therapeutic approaches; earlier initiation of treatment; more effective use of resources for screening populations; and an enhanced experience for people with or at risk of breast cancer and their families. The challenge to funding bodies and researchers in all disciplines is to focus on these gaps and to drive advances in knowledge into improvements in patient care

    Ethics and health care 'underfunding'

    Get PDF
    There are continual “crises” in health care systems worldwide as producer and patient groups unify and decry the “underfunding” of health care. Sometimes this cacophony is the self interest of profit seeking producers and often it is advocacy of unproven therapies. Such pressure is to be expected and needs careful management by explicit rationing criteria which determine who gets access to what health care. Science and rationality, however, are unfortunately, rarely the rules of conduct in the medical market-place

    Texas Physicians\u27 Awareness and Utilization of Genetic Services

    Get PDF
    The number of disorders for which genetic testing is available has increased nearly 500% in the past 15 years. Access to the majority of genetic tests and services hinges on physicians’ ability to identify patients at risk for genetic disease and provide appropriate testing and counseling or refer to genetic specialists. Recent research demonstrates the need for referrals to genetic specialists by showing that many physicians lack skills required to perform appropriate genetic services, such as making proper risk assessments, providing genetic counseling, ordering genetic testing and interpreting results. However, little research exists on physicians’ awareness and utilization of genetic services. In this study, an electronic survey evaluating practicing physicians’ awareness of, utilization of and perceived barriers to genetic services in Texas was distributed via state physician organizations. Of the 157 participants, approximately half reported they were moderately or very aware of genetic testing and services in their area. Very few reported awareness of telemedicine services. Over two-thirds reported never or rarely referring to genetic counselors or other genetic specialists, despite 75% reporting they had noticed an increased impact of genetics on their field and 61% reporting they had discussed genetics more in their day-to-day practice in the last 5-10 years. Only 20% reported genetics was very integral to their specialty. Over three-fourths of all participants indicated interest in learning more about genetics, genetic testing and genetic services. Among the most frequently chosen barriers to genetic counselors were awareness-related barriers such as not knowing how to refer to a genetic counselor. Responses to many items varied significantly by medical specialty. The results identify a need to increase awareness of genetic services and referral logistics. Specific findings can help direct outreach efforts to educate clinicians, such as developing clinically meaningful, specialty-specific educational objectives

    How and why do South Asians attend GUM clinics? Evidence from contrasting GUM clinics across England

    Get PDF
    Background: Improving access to sexual healthcare is a priority in the UK, especially for ethnic minorities. Though South Asians in the UK report low levels of sexual ill health, few data exist regarding their use of genitourinary medicine (GUM) services. Objectives: To describe reasons for attendance at GUM clinics among individuals of South Asian origin relative to patients of other ethnicities. Methods: 4600 new attendees (5% South Asian; n=226) at seven sociodemographically and geographically contrasting GUM clinics across England completed a questionnaire between October 2004 and March 2005, which were linked to routine clinical data. Results: South Asians were more likely than other groups to be signposted to the GUM clinic by another health service-for example, in women 14% versus 8% respectively (p=0.005) reported doing so from a family planning clinic. These women also reported that they would be less likely to go to the clinic if their symptoms resolved spontaneously compared with other women (51% vs 31%, p=0.024). However, relative to other clinic attendees, no differences in the proportions of South Asians who had acute STI(s) diagnosed at clinic were noted. Furthermore, South Asian men were more likely to report as their reason for attendance that they wanted an HIV test (23.4% vs 14.8%, p=0.005). Conclusion: Despite having similar STI care needs to attendees from other ethnic groups, South Asians, especially women, may be reluctant to seek care from GUM clinics, especially if their symptoms resolve. Sexual health services need to develop locally-delivered and culturally-appropriate initiatives to improve care pathways

    IT and the NHS: Investigating different perspectives of IT using soft systems methodology

    Get PDF
    The UK NHS National Programme for IT has been criticized for a lack of clinical engagement. This paper uses a soft systems methodology (SSM) analysis of a case study from the use of electronic systems within a National Health Service (NHS) Mental Health Trust in the United Kingdom (UK) to explore the legal and ethical implications of the failure to develop clinical systems which are fit for purpose. Soft systems methodology (SSM) was used as a theoretical model both to derive deeper insights into the survey data and suggest how communication between those producing information and those using it, could be improved. Multiple methods were employed which included a postal survey and participant interviews to triangulate the data The use of SSM reinforced the concept that the national IT programme is based on a 'hard' systems view and does not take local factors (which are related to 'soft systems' thinking) into account. The study found administrative staff to be a crucial link between clinicians and information departments and highlighted the need for a joint-up information strategy and integrated systems. The article concludes with a discussion of the legal and ethical implications of the findings and the lessons for the broader UK national programme. It argues that the failure to deliver systems that are fit for purpose is not value neutral but an ethical issue

    Multilevel Weighted Support Vector Machine for Classification on Healthcare Data with Missing Values

    Full text link
    This work is motivated by the needs of predictive analytics on healthcare data as represented by Electronic Medical Records. Such data is invariably problematic: noisy, with missing entries, with imbalance in classes of interests, leading to serious bias in predictive modeling. Since standard data mining methods often produce poor performance measures, we argue for development of specialized techniques of data-preprocessing and classification. In this paper, we propose a new method to simultaneously classify large datasets and reduce the effects of missing values. It is based on a multilevel framework of the cost-sensitive SVM and the expected maximization imputation method for missing values, which relies on iterated regression analyses. We compare classification results of multilevel SVM-based algorithms on public benchmark datasets with imbalanced classes and missing values as well as real data in health applications, and show that our multilevel SVM-based method produces fast, and more accurate and robust classification results.Comment: arXiv admin note: substantial text overlap with arXiv:1503.0625
