Uptake of screening for breast cancer in patients with mental health problems

OBJECTIVES: Mental illness is associated with physical illness and mortality from a variety of causes including cancer. There is little information on screening attendance among the mentally ill population. An audit was conducted of a breast screening service in inner London to determine uptake rates in women with mental illness. DESIGN: Cross sectional data linkage study of the local screening register and patients of the local psychiatric units. Screening uptake rates in all patients, those with a history of multiple detention in hospital, and those with psychosis were compared with the local reference population. SETTING: Women in three inner London boroughs. PARTICIPANTS: Screening records for 933 psychiatric patients and 44 195 women without mental health problems aged 50 to 64 years. MAIN RESULTS: Overall, psychiatric patients were as likely as the reference group to attend breast screening. Patients with a history of multiple detention were significantly less likely to attend (OR = 0.40, 0.29 to 0.55; p<0.001), as were patients with a diagnosis of psychosis (OR = 0.33, 0.18 to 0.61; p<0.01). Increasing age, a history of detention in hospital, and social deprivation remained independent predictors for non-attendance. CONCLUSION: Women with severe mental health problems may be less likely to attend national screening programmes such as breast screening, and action should be taken to overcome the barriers to attendance.     

Social capital and adherence to cervical and breast cancer screening guidelines: a cross‐sectional study in rural Crete

Breast and cervical cancers are among the leading causes of female mortality. The reasons that make women adhere, or not, to screening guidelines are not only related to individual and health characteristics but are also placed in a wider social and cultural context. Social capital might facilitate the dissemination of relevant knowledge of and the adherence to cancer screening guidelines. This cross‐sectional study explored the associations of individual‐level social capital with breast and cervical cancer screening and the knowledge for the existence of relevant screening tests (Pap test and mammography) in the municipality of Gorgolaini, a rural area in Crete, Greece. A random sample of 131 of the 592 women of the 2001 electoral register were invited to participate in the study and 125 completed the Social Capital Questionnaire and two questions on self‐reported health knowledge and behaviour (participation rate 95.4%). Women were eligible to participate if they were aged 35–75, had lived in the area for the last 10 years and were of Greek origin. Multiple logistic regressions were performed to establish associations among each social capital factor (total, participation in the community, value of life, tolerance for diversity, feelings of safety, family/friends connections) and knowledge of and adherence to breast and cervical cancer screening guidelines after adjustment for confounders. Our results suggest that early detection of breast and cervical cancers may be facilitated when taking into account the social context of the population.     

Barriers to breast and cervical cancer screening for women with physical disability: A review

ABSTRACT

This review critically examined the barriers to breast and cervical cancer screening services for women with physical disability and discussed ways forward to change practice. When compared to the rest of the community, women with disability were less likely to use preventive health screening services for multiple reasons. Moreover, women with disability live longer than in previous years, and as age is linked to an increased risk of developing cancer, it is imperative that the barriers to screening for these women become a focus of discussion. We designed an integrative literature review to investigate this. Multiple databases were systematically searched for literature published between 2001 and 2013. Search terms used were a combination (AND/OR) of key terms. After excluding duplicates and articles not meeting the eligibility criteria, twenty-five articles were systematically and critically reviewed. Sociodemographic factors were associated with less access to preventive health screening for women with disability. The literature reviewed indicated that this was complicated further by three prominent barriers: health insurance, health care workers, and physical barriers. Sociodemographic, health insurance, health workers, and physical barriers impair access for disabled women to breast and cervical cancer screening, which are vital measures in the timely detection of breast and cervical cancers and preventable morbidity and mortality. Measures are needed to address these limiting factors for women with disability so that they can be active participants in health care, rather than being marginalized because of their disability.     

A Bayesian approach to analysing the cost-effectiveness of two primary care interventions aimed at improving attendance for breast screening

AIMS: To assess the cost-effectiveness of two primary care interventions, a letter and a flag, aimed at improving attendance for breast screening among (i) all women invited for breast screening and (ii) non-attenders. METHODS: A probabilistic decision analytic model was developed using Markov chain Monte Carlo simulation implemented in WinBUGS. The model was populated using economic and effectiveness data collected alongside two randomised controlled trials. RESULTS: For all women invited, the incremental cost-effectiveness ratio (ICER) for the letter compared with no intervention is 27 pounds per additional attendance, and the ICER for the combined letter and flag intervention compared to the letter alone is 171 pounds. The corresponding ICERs for non-attenders are 41 pounds and 90 pounds. The flag intervention is an inefficient option in both settings. A large proportion of the costs fall on the practices (25-67%), depending on the intervention and target population. The total costs incurred do not, however, seem prohibitive.Expected value of perfect information suggests that there is greater value in carrying out further research on the intervention implemented among all women invited for breast screening rather than on non-attenders. CONCLUSIONS: The flag intervention alone does not appear to be an efficient option. The choice between the letter and both interventions combined is subjective, depending on the willingness to pay for an additional screening attendance.     

Screening for breast cancer in Catalonia: Which policy is to be preferred?

Background: the effects and costs of different policies forbreast cancer screening in Catalonia (Spain) were analysed,to give a basis for setting priorities and deciding on the introductionof a screening programme. Methods: the MISCAN (MIcrosimulationSCreening ANalysis) model of the natural history of breast cancerwas used. The epidemiology of breast cancer in Catalonia andthe demography of the Catalan population was taken into accountas well as the results on mortality reduction from a Swedishoverview of breast cancer screening trials. Results: the reductionin breast cancer mortality in the total female population dueto a screening programme for the age group 50–64 yearswould be 16, 12 and 9%, with screening intervals of one, twoand three years respectively. The cost-effectiveness ratios(CE ratios) for these scenarios were 924,000, 730,000 and 719,000pesetas (P_t) per life-year gained respectively (5% discounting).The most cost-effective screening scenario is the one in whichwomen aged 50–69 years are screened with an interval ofthree years with a mortality reduction of approximately 12%in the total female population (CE ratio = 694,000 P_t). Screeninguntil the age of 69 years (two year interval) was almost ascost-effective as screening the age group 50–64 yearswith a two year interval, with a reduction in breast cancermortality of 15%. Extension to under the age of 50 years resultedin diverging results depending on the assumptions for improvementin prognosis for younger women (40–49 years). Conclusion:if the extension of a two yearly screening programme for womenaged 50–64 years is considered (mortality reduction of12%), extension to older women would be more advisable, basedon proven benefits and costs, than extension to younger agegroups.     

Medical error: a discussion of the medical construction of error and suggestions for reforms of medical education to decrease error

INTRODUCTION: There is a growing public perception that serious medical error is commonplace and largely tolerated by the medical profession. The Government and medical establishment's response to this perceived epidemic of error has included tighter controls over practising doctors and individual stick-and-carrot reforms of medical practice. DISCUSSION: This paper critically reviews the literature on medical error, professional socialization and medical student education, and suggests that common themes such as uncertainty, necessary fallibility, exclusivity of professional judgement and extensive use of medical networks find their genesis, in part, in aspects of medical education and socialization into medicine. The nature and comparative failure of recent reforms of medical practice and the tension between the individualistic nature of the reforms and the collegiate nature of the medical profession are discussed. CONCLUSION: A more theoretically informed and longitudinal approach to decreasing medical error might be to address the genesis of medical thinking about error through reforms to the aspects of medical education and professional socialization that help to create and perpetuate the existence of avoidable error, and reinforce medical collusion concerning error. Further changes in the curriculum to emphasize team working, communication skills, evidence-based practice and strategies for managing uncertainty are therefore potentially key components in helping tomorrow's doctors to discuss, cope with and commit fewer medical errors.

Improving informed consent: pilot of a decision aid for women invited to participate in a breast cancer prevention trial (IBIS-II DCIS)

Background  Patients and clinicians report difficulties with the process of informed consent to clinical trials and audiotape audits show that critical information is often omitted or poorly presented. Decision aids (DAs) may assist in improving consent.
Aims  This study piloted a DA booklet for a high priority breast cancer prevention trial, IBIS-II DCIS, which compares the efficacy of an aromatase inhibitor (anastrozole) with tamoxifen in women who have had surgery for ductal carcinoma in situ (DCIS).
Method  Thirty-one Australian women participating in the IBIS-I breast cancer prevention trial and who are currently in follow-up agreed to read the IBIS-II DCIS participant information sheet and the DCIS DA booklet, complete a set of standardized questionnaires, and provide feedback on the DA via a semi-structured phone interview.
Results  Women found the DA helpful in deciding about trial participation, reporting that it aided their understanding over and above the approved IBIS-II DCIS participant information sheet and was not anxiety provoking. Women's understanding of the rationale and methods of clinical trials and the IBIS-II DCIS trial was very good; with more than 80% of items answered correctly. The only areas that were not understood well were the concepts of randomization and blinding.
Conclusions  This study suggests that the DA will be acceptable to and valued by potential participants in the IBIS-II DCIS study. The revised DA is currently being evaluated prospectively in a randomized controlled trial. If successful, such DAs could transform the consent process to large clinical trials and may also reduce dropout rates.     

Barriers and enablers to adolescent self-consent for vaccination: A mixed-methods evidence synthesis

Introduction

The recent global expansion of routine adolescent vaccination programmes has the potential to protect young people against infectious diseases and improve their health. Although the legal framework in many countries permits young people to consent for vaccinations if competent, lack of written parental consent can still prevent uptake. We aimed to review systematically the associated barriers and enablers to implementation of adolescent self-consent procedures.

Multipoint development of the weighted pairwise correlation (WPC) linkage method for pedigrees of arbitrary size and application to the analysis of breast cancer and alcoholism familial data.

The weighted pairwise correlation (WPC) method is a simple and powerful model-free method of linkage analysis that has the advantages of being applicable to binary, ordered categorical, quantitative, or censored traits, and to consider all pairs of relatives in large pedigrees. The originally implemented approach was limited to the use of the identical by state (IBS) information, and we recently extended the WPC method to incorporate the identical by descent (IBD) information for two-point linkage analysis. Here, we develop a multipoint WPC method suitable for pedigrees of arbitrary size and large number of markers. The multipoint IBD estimation procedure for relative pairs is based on the efficient regression approach developed for pedigrees implemented in SOLAR. A robust and fast Monte-Carlo procedure is used to determine reliable P values. Application of the method to the 214 pedigrees from the Breast Cancer Linkage Consortium provided for the Genetic Analysis Workshop (GAW) 9 shows that multipoint WPC statistic values were not far from two-point maximum lod-score values obtained by the classical parametric linkage method and were higher than multipoint variance component analysis lod-scores obtained with SOLAR. The multipoint WPC method is also used to analyze the familial Collaborative Study of the Genetics of Alcoholism data on alcoholism released for GAW11. It allows a better specification of the linkage results previously obtained within the chromosome 4 region.     

Behavioral and social sciences theories and models: are they used in unintentional injury prevention research?

Behavioral and social sciences theories and models have the potential to enhance efforts to reduce unintentional injuries. The authors reviewed the published literature on behavioral and social science theory applications to unintentional injury problems to enumerate and categorize the ways different theories and models are used in injury prevention research. The authors conducted a systematic review to evaluate the published literature from 1980 to 2001 on behavioral and social science theory applications to unintentional injury prevention and control. Electronic database searches in PubMed and PsycINFO identified articles that combined behavioral and social sciences theories and models and injury causes. The authors identified some articles that examined behavioral and social science theories and models and unintentional injury topics, but found that several important theories have never been applied to unintentional injury prevention. Among the articles identified, the PRECEDE PROCEED Model was cited most frequently, followed by the Theory of Reasoned Action/Theory of Planned Behavior and Health Belief Model. When behavioral and social sciences theories and models were applied to unintentional injury topics, they were most frequently used to guide program design, implementation or develop evaluation measures; few examples of theory testing were found. Results suggest that the use of behavioral and social sciences theories and models in unintentional injury prevention research is only marginally represented in the mainstream, peer-reviewed literature. Both the fields of injury prevention and behavioral and social sciences could benefit from greater collaborative research to enhance behavioral approaches to injury control.
