Abstract
OBJECTIVES Integration of pharmacogenomics into clinical care is being studied in multiple disciplines. We hypothesized that understanding attitudes and perceptions of anesthesiologists, critical care and pain medicine providers would uncover unique considerations for future implementation within perioperative care. METHODS A survey (multiple choice and Likert-scale) was administered to providers within our Department of Anesthesia and Critical Care prior to initiation of a department-wide prospective pharmacogenomics implementation program. The survey addressed knowledge, perceptions, experiences, resources and barriers. RESULTS Of 153 providers contacted, 149 (97%) completed the survey. Almost all providers (92%) said that genetic results influence drug therapy, and few (22%) were skeptical about the usefulness of pharmacogenomics. Despite this enthusiasm, 87% said their awareness about pharmacogenomic information is lacking. Feeling well-informed about pharmacogenomics was directly related to years in practice/experience: only 38% of trainees reported being well-informed, compared to 46% of those with 1-10 years of experience, and nearly two-thirds with 11+ years (P < 0.05). Regarding barriers, providers reported uncertainty about availability of testing, turnaround time and whether testing is worth financial costs. CONCLUSIONS Anesthesiology, critical care and pain medicine providers are optimistic about the potential clinical utility of pharmacogenomics, but are uncertain about practical aspects of testing and desire clear guidelines on the use of results. These findings may inform future institutional efforts toward greater integration of genomic results to improve medication-related outcomes.

BMC FAMILY PRACTICE 2021; 22:141. [PMID: 34210270 PMCID: PMC8247620 DOI: 10.1186/s12875-021-01492-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 02/21/2021] [Accepted: 06/09/2021] [Indexed: 11/10/2022]
Abstract
BACKGROUND Genetic screening (GS), defined as the clinical testing of a population to identify asymptomatic individuals with the aim of providing those identified as high risk with prevention, early treatment, or reproductive options. Genetic screening (GS) improves patient outcomes and is accessible to the community. Family physicians (FPs) are ideally placed to offer GS. There is a need for FPs to adopt GS to address anticipated genetic specialist shortages. OBJECTIVE To explore FP attitudes, perceived roles, motivators and barriers, towards GS; and explore similarities and differences between private and public sector FPs. METHODS We developed a semi-structured interview guide using existing literature. We interviewed private and public sector FPs recruited by purposive, convenience and snowballing strategies, by telephone or video to theme saturation. All sessions were audio-recorded, transcribed and coded for themes by two independent researchers with an adjudicator. RESULTS Thirty FPs were interviewed (15 private, 15 public). Theme saturation was reached for each group. A total of 12 themes (6 common, 3 from private-practice participants, 3 public-employed participants) emerged. Six common major themes emerged: personal lack of training and experience, roles and relevance of GS to family medicine, reluctance and resistance to adding GS to practice, FP motivations for adoption, patient factors as barrier, and potential solutions. Three themes (all facilitators) were unique to the private group: strong rapport with patients, high practice autonomy, and high patient literacy. Three themes (all barriers) were unique to the public group: lack of control, patients' lower socioeconomic status, and rigid administrative infrastructure. CONCLUSION FPs are motivated to incorporate GS but need support for implementation. Policy-makers should consider the practice setting when introducing new screening functions. Strategies to change FP behaviours should be sensitive to their sense of autonomy, and the external factors (either as facilitators or as barriers) shaping FP practices in a given clinical setting.

Abstract
This study aimed to investigate awareness, attitudes, and perspectives on precision medicine among health professionals in Korea and to identify issues that need to be addressed before implementing precision medicine. Mixed methods research was applied. For qualitative research, a semi-structured focus group interview was conducted with six health professionals. For quantitative research, a self-reported survey was administered. A total of 542 health professionals participated in the survey, and 526 completed the entire questionnaire. Health professionals showed positive attitudes toward precision medicine. About 95-96% of respondents agreed that precision medicine will be effective in treatment and precise diagnosis, and 69.9% reported that they would participate as study subjects. Meanwhile, they expressed concerns regarding educating patients and health professionals in precision medicine and developing research and data sharing infrastructure. Also, they emphasized the importance of developing precision medicine in an equitable way. Despite varying levels of awareness of precision medicine, the health professionals expressed a willingness to engage in precision medicine research, and recommended that health professionals work closely with policymakers to design precision medicine in a way that can be effectively adopted. Health professionals showed had a positive, but cautious, attitude toward precision medicine. The results of this study suggest areas to be addressed before ushering in precision medicine in Korea.

Abstract
OBJECTIVES The aim of this study was to demonstrate the utility of a comprehensive program involving management-based evidence, telemedicine, and patient navigation to provide genetic counseling services for patients with ovarian and breast cancer across a geographically large health care system. METHODS We identified all patients with newly diagnosed ovarian and breast cancer in our health care system from January 2013 to December 2015 through the cancer registry. Referral characteristics and testing outcomes were recorded for each year and compared using the χ or Fisher exact test. RESULTS Because the implementation of this program, the number of new ovarian cancer cases remained constant (109-112 cases/year) but patients referred for genetic counseling increased annually from 37% to 43% to 96% (P < 0.05). The percentage of ovarian cancer patients who underwent genetic testing increased annually from 24% to 27% to 53% (P < 0.05). The number of new breast cancer patients was constant (1543-1638 cases/year). The percentage of patients with triple negative breast cancer referred for genetic counseling rose from 69% in 2013 to 91% in 2015; the percentage of patients who underwent testing increased annually from 59% to 86% (P < 0.05). Of women with breast cancer diagnosed at less than 45 years of age, 78% to 85% were referred for genetic counseling across this period; the percentage of patients who underwent testing increased annually from 66% to 82% (P < 0.05). Patient navigation was initiated and was available to all patients in the system during this period. Telemedicine consults were performed in 118 breast/ovarian patients (6%) during this period. CONCLUSIONS A comprehensive program may improve access to effective genetic counseling services in patients with ovarian and breast cancer despite geographic barriers.

Abstract
Aim This study aimed to examine pharmacogenomic test results and patient perspectives at an academic cardiovascular medicine clinic. Patients & methods Test results for three common cardiovascular drug-gene tests (warfarin-CYP2C9-VKORC1, clopidogrel-CYP2C19 and simvastatin-SLCO1B1) of 208 patients in the Ohio State University-Coriell Personalized Medicine Collaborative were examined to determine the incidence of potentially actionable test results. A post-hoc, anonymous, patient survey was also conducted. Results Potentially actionable test results for at least one of the three drug-gene tests were determined in 170 (82%) patients. Survey responses (n = 134) suggested that patients generally considered their test results to be important (median of 7.5 on a 10-point scale of importance) and were interested (median of 7.3 on a 10-point scale of interest) in a Clinical Pharmacogenomic Service. Conclusion Attitudes toward pharmacogenomic testing were generally favorable, and potentially actionable test results were not uncommon in this cardiovascular medicine cohort.

Abstract
AIM Our aim was to evaluate physicians' attitudes toward pharmacogenetic testing before and after pharmacogenetic education. METHODS In total, 12 physicians (˜40% response rate) completed a survey with eight questions on 10-point scales on their attitudes toward pharmacogenetic testing before and after a 1-h grand rounds presentation on pharmacogenetics. Differences in question scores overall, among training levels (resident/fellow/attending), and specific drugs (clopidogrel/simvastatin/warfarin) were assessed using Wilcoxon signed-rank and exact Kruskal-Wallis tests. RESULTS & CONCLUSION The scores for all eight questions increased, with statistically significant (p < 0.05) increases for four out of eight questions. The scores were similar among training levels, but the postscores for clopidogrel were significantly higher than for simvastatin and warfarin. In conclusion, brief pharmacogenetic education can significantly affect physicians' attitudes toward pharmacogenetic testing.

Gatekeepers or intermediaries? The role of clinicians in commercial genomic testing. PLoS One 2014; 9:e108484.

Abstract
Background Many commentators on “direct-to-consumer” genetic risk information have raised concerns that giving results to individuals with insufficient knowledge and training in genomics may harm consumers, the health care system, and society. In response, several commercial laboratories offering genomic risk profiling have shifted to more traditional “direct-to-provider” (DTP) marketing strategies, repositioning clinicians as the intended recipients of advertising of laboratory services and as gatekeepers to personal genomic information. Increasing popularity of next generation sequencing puts a premium on ensuring that those who are charged with interpreting, translating, communicating and managing commercial genomic risk information are appropriately equipped for the job. To shed light on their gatekeeping role, we conducted a study to assess how and why early clinical users of genomic risk assessment incorporate these tools in their clinical practices and how they interpret genomic information for their patients. Methods and Findings We conducted qualitative in-depth interviews with 18 clinicians providing genomic risk assessment services to their patients in partnership with DNA Direct and Navigenics. Our findings suggest that clinicians learned most of what they knew about genomics directly from the commercial laboratories. Clinicians rely on the expertise of the commercial laboratories without the ability to critically evaluate the knowledge or assess risks. Conclusions DTP service delivery model cannot guarantee that providers will have adequate expertise or sound clinical judgment. Even if clinicians want greater genomic knowledge, the current market structure is unlikely to build the independent substantive expertise of clinicians, but rather promote its continued outsourcing. Because commercial laboratories have the most “skin in the game” financially, genetics professionals and policymakers should scrutinize the scientific validity and clinical soundness of the process by which these laboratories interpret their findings to assess whether self-interested commercial sources are the most appropriate entities for gate-keeping genomic interpretation.

Abstract
INTRODUCTION Preconception care recognizes that many adolescent girls and young women will be thrust into motherhood without the knowledge, skills or support they need. Sixty million adolescents give birth each year worldwide, even though pregnancy in adolescence has mortality rates at least twice as high as pregnancy in women aged 20-29 years. Reproductive planning and contraceptive use can prevent unintended pregnancies, unsafe abortions and sexually-transmitted infections in adolescent girls and women. Smaller families also mean better nutrition and development opportunities, yet 222 million couples continue to lack access to modern contraception. METHOD A systematic review and meta-analysis of the evidence was conducted to ascertain the possible impact of preconception care for adolescents, women and couples of reproductive age on MNCH outcomes. A comprehensive strategy was used to search electronic reference libraries, and both observational and clinical controlled trials were included. Cross-referencing and a separate search strategy for each preconception risk and intervention ensured wider study capture. RESULTS Comprehensive interventions can prevent first pregnancy in adolescence by 15% and repeat adolescent pregnancy by 37%. Such interventions should address underlying social and community factors, include sexual and reproductive health services, contraceptive provision; personal development programs and emphasizes completion of education. Appropriate birth spacing (18-24 months from birth to next pregnancy compared to short intervals <6 months) can significantly lower maternal mortality, preterm births, stillbirths, low birth weight and early neonatal deaths. CONCLUSION Improving adolescent health and preventing adolescent pregnancy; and promotion of birth spacing through increasing correct and consistent use of effective contraception are fundamental to preconception care. Promoting reproductive planning on a wider scale is closely interlinked with the reliable provision of effective contraception, however, innovative strategies will need to be devised, or existing strategies such as community-based health workers and peer educators may be expanded, to encourage girls and women to plan their families.

Abstract
Sickle cell disease (SCD) is a debilitating illness that affects the life expectancy of patients. It is possible to test for SCD before birth, to allow for reproductive options to parents. However, under Cameroonian Law, voluntary abortion is a criminal offense and medical abortion is permitted only "…if it is done by an authorized professional and justified by the need to save the mother from grave health jeopardy." The objective of the present study was to compare the views of Cameroonian doctors, parents with at least one living SCD-affected child, and adult SCD patients, regarding prenatal genetic diagnosis and termination of SCD-affected pregnancy. We conducted a quantitative sociological survey of 110 doctors, 130 parents, and 89 adult patients. The majority accepted the prenatal genetic diagnosis for SCD (78.7%, 89.8%, and 89.2%, respectively). Parents (62.5%) were more in favor of termination of SCD-affected pregnancy, than doctors and adults patients (36.1% and 40.9% acceptance, respectively). Parents and patients who found medical abortion acceptable cited fear to have a SCD-affected child (98.1 and 88.9%) and the poor quality of the affected child's health (92.6% and 81.5%). The data underscore the urgency of policy action to place emphasis on: premarital screening, early detection and care of SCD, socio-economic measures to assist SCD-affected families, appropriateness to consider maternal distress due to fetal anomalies in medical abortion legislation. These novel findings signal potential value-based conflicts on the horizon, and can usefully inform the future policy actions in the African continent as OMICS biotechnologies are increasingly employed in global health. To the best of our knowledge, the present study is the first attempt in sub-Saharan Africa to attempt to triangulate the views of multiple stakeholders towards prenatal diagnosis of SCD and termination of an affected pregnancy.

Abstract
Background We describe the study design, procedures, and development of the risk counseling protocol used in a randomized controlled trial to evaluate the impact of genetic testing for diabetes mellitus (DM) on psychological, health behavior, and clinical outcomes. Methods/Design Eligible patients are aged 21 to 65 years with body mass index (BMI) ≥27 kg/m2 and no prior diagnosis of DM. At baseline, conventional DM risk factors are assessed, and blood is drawn for possible genetic testing. Participants are randomized to receive conventional risk counseling for DM with eye disease counseling or with genetic test results. The counseling protocol was pilot tested to identify an acceptable graphical format for conveying risk estimates and match the length of the eye disease to genetic counseling. Risk estimates are presented with a vertical bar graph denoting risk level with colors and descriptors. After receiving either genetic counseling regarding risk for DM or control counseling on eye disease, brief lifestyle counseling for prevention of DM is provided to all participants. Discussion A standardized risk counseling protocol is being used in a randomized trial of 600 participants. Results of this trial will inform policy about whether risk counseling should include genetic counseling. Trial registration ClinicalTrials.gov Identifier NCT01060540

Abstract
PURPOSE Appropriate management of autosomal dominant disorders reduces morbidity and mortality but relies on identifying which family members are affected. Genetic testing may identify relatives needing follow-up but is underused. We conducted this study to identify barriers to genetic testing for one disorder, hereditary hemorrhagic telangiectasia. METHODS Surveys and online discussion groups with people from hereditary hemorrhagic telangiectasia families. RESULTS Multiple barriers to hereditary hemorrhagic telangiectasia genetic testing were identified including lack of knowledge about genetic testing, problems with access, and emotional barriers. Many participants did not understand the rationale for hereditary hemorrhagic telangiectasia testing or benefits of early detection; believed that genetic testing is expensive and not covered by insurance; and believed that primary care providers do not know how to order genetic testing. Access to hereditary hemorrhagic telangiectasia testing is limited by distance from a hereditary hemorrhagic telangiectasia center or a genetics clinic. Emotional barriers include fear of insurance discrimination; denial of having hereditary hemorrhagic telangiectasia or being at risk; and guilt and stigma. CONCLUSION Voluntary disease organizations should develop and disseminate brief educational materials that describe the rationale for genetic testing and emphasize the benefits of early detection and treatment. In addition, laboratories offering genetic testing should provide support for primary care physicians to order and interpret genetic tests.

Abstract
To develop a benchmark measure of US physicians' level of knowledge and extent of use of pharmacogenomic testing, we conducted an anonymous, cross-sectional, fax-based, national survey. Of 397,832 physicians receiving the survey questionnaire, 10,303 (3%) completed and returned it; the respondents were representative of the overall US physician population. The factors associated with the decision to test were evaluated using χ(2) and multivariate logistic regression. Overall, 97.6% of responding physicians agreed that genetic variations may influence drug response, but only 10.3% felt adequately informed about pharmacogenomic testing. Only 12.9% of physicians had ordered a test in the previous 6 months, and 26.4% anticipated ordering a test in the next 6 months. Early and future adopters of testing were more likely to have received training in pharmacogenomics, but only 29.0% of physicians overall had received any education in the field. Our findings highlight the need for more effective physician education on the clinical value, availability, and interpretation of pharmacogenomic tests.

Abstract
To assess the educational needs of North Carolina primary care physicians (PCPs) about direct-to-consumer (DTC) genetic testing, surveys were mailed to 2,402 family and internal medicine providers in North Carolina. Out of 382 respondents, 323 (85%) felt unprepared to answer patient questions and 282 (74%) reported wanting to learn about DTC genetic testing. A total of 148 (39%) were aware of DTC genetic testing. Among these, 63 (43%) thought DTC genetic testing was clinically useful. PCPs who felt either unprepared to answer patient questions (OR = 0.354, p = 0.01) or that DTC genetic testing was clinically useful (OR = 5.783, p = 0.00) were more likely to want to learn about DTC genetic testing. PCPs are interested in learning about DTC genetic testing, but are mostly unaware of DTC testing and feel unprepared to help patients with DTC testing results. Familiar and trusted channels that provide the information and tools PCPs need to help answer patient's questions and manage their care should be used when creating educational programs.

Genomic risk profiling: attitudes and use in personal and clinical care of primary care physicians who offer risk profiling. J Gen Intern Med 2011; 26:834-40. [PMID: 21311998 PMCID: PMC3138989 DOI: 10.1007/s11606-011-1651-7] [Citation(s) in RCA: 55] [Impact Index Per Article: 4.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/26/2010] [Revised: 11/16/2010] [Accepted: 01/18/2011] [Indexed: 01/08/2023]
Abstract
BACKGROUND Genomic risk profiling involves the analysis of genetic variations linked through statistical associations to a range of disease states. There is considerable controversy as to how, and even whether, to incorporate these tests into routine medical care. OBJECTIVE To assess physician attitudes and uptake of genomic risk profiling among an 'early adopter' practice group. DESIGN We surveyed members of MDVIP, a national group of primary care physicians (PCPs), currently offering genomic risk profiling as part of their practice. POPULATION All physicians in the MDVIP network (N = 356) RESULTS We obtained a 44% response rate. One third of respondents had ordered a test for themselves and 42% for a patient. The odds of having ordered personal testing were 10.51-fold higher for those who felt well-informed about genomic risk testing (p < 0.0001). Of those who had not ordered a test for themselves, 60% expressed concerns for patients regarding discrimination by life and long-term/disability insurers, 61% about test cost, and 62% about clinical utility. The odds of ordering testing for their patients was 8.29-fold higher among respondents who had ordered testing for themselves (p < 0.0001). Of those who had ordered testing for patients, concerns about insurance coverage (p = 0.014) and uncertain clinical utility (p = 0.034) were associated with a lower relative frequency of intention to order testing again in the future. CONCLUSIONS Our findings demonstrate that respondent familiarity was a key predictor of physician ordering behavior and clinical utility was a primary concern for genomic risk profiling. Educational and interpretive support may enhance uptake of genomic risk profiling.

Abstract
AIMS Pharmacogenetic (PGx) tests, intended to inform therapeutic decision making through prediction of patient likelihood to respond to or experience an adverse effect from a specific treatment, may also generate ancillary, or incidental, disease information unrelated to the purpose for which the test was ordered. To assess attitudes toward PGx testing, ancillary disease risk information, and related clinical issues, we conducted a series of focus groups among health professionals. RESULTS Twenty-one primary care and genetics professionals from Durham, NC, were recruited to participate in three focus groups (two of primary care professionals [PCPs] and one of geneticists). Overall, interest in PGx testing was positive, though enthusiasm was reserved among PCPs due to concerns about clinical utility, insurance coverage, delay of treatment, and ability to communicate and interpret ancillary disease risk information. Although many PCPs felt an obligation to disclose information about ancillary disease risk, geneticists did not believe that it was always necessary, noting the complexities of genetic risk results such as incomplete penetrance. CONCLUSION This pilot study found that health professionals' interest in the use of PGx testing was limited by concerns about the lack of evidence of clinical utility and their ability to interpret and communicate ancillary disease risk information to patients. Additional educational resources, access to genetic specialists, and clear clinical guidelines about the use of PGx testing would greatly facilitate appropriate use of testing.

Abstract
Little is known about attitudes of parents of Sickle Cell Anemia patients in sub-Saharan Africa regarding prenatal genetic diagnosis and termination of an affected pregnancy. In this study, structured face-to-face interviews were conducted with a sample of 130 parents in Cameroon that had at least one living child with Sickle Cell Anemia. The majority of participants lived in urban areas (89%), were female (80%), Christian (93%), married (60.2%) in monogamous households (81.1%), were employed (61.7%), and had at least a secondary or tertiary education (82%). The majority of parents accepted the principle of prenatal genetic diagnosis for Sickle Cell Anemia (89.8%) and termination of pregnancy (62.5%). Acceptance of the principle of pregnancy termination increased with unemployment (p<.01) and single marital status (p<.05). The results of this study suggest Cameroonian parents with children affected with Sickle Cell Anemia generally accept the principles of prenatal diagnosis and in some cases termination of a pregnancy affected with Sickle Cell Anemia. Additional findings, policy and practice implications, and research recommendations are presented.

Abstract
The clinical utility of many emerging genetic technologies has yet to be established. For many new genetic tests, no practice guidelines are available to help clinicians decide when and how to use them in practice. The clinical and public health implications of new genetic technologies are easiest to evaluate when these tests are compared with other genetic tests, including those already well established in clinical practice. Genetic tests can be divided into different categories based on their intent as follows: (1) to establish a diagnosis (genetic diagnostic tests), (2) to classify disease processes to assist management (gene expression profiling), (3) to predict drug response or side effects (pharmacogenomic tests), and (4) to predict susceptibility to disease (genetic susceptibility testing). As new genetic tests emerge, their translation into practice will depend on their performance based on laboratory standards, but also on their ability to enhance prevention or assist clinicians in diagnosing and treating patients. This article reviews the clinical and public health implications of different types of genetic tests, the evaluation of genetic tests from a public health perspective, and the need for partnership to achieve the potential for benefit of new genetic technologies.

Abstract
Nutritional genomics has reached the public through applications of the Human Genome Project offered direct to consumers (DTC). The ability to pursue nutrigenetic testing without the involvement of a health care professional has received considerable attention from academic and policy commentators. To better understand the knowledge and attitudes of Canadian health care professionals regarding nutritional genomics and nutrigenetic testing, qualitative research in the form of focus group discussions was undertaken. Four key themes emerged: (1) concerns over DTC testing; (2) lack of health care professional competency; (3) genetic scepticism and inevitability; (4) expectation of regulation. Together, they indicate that health care professionals have little knowledge about nutritional genomics and hold contradictory attitudes towards genomics in general, and to nutritional genomics in particular. Respondents argue in favour of a delivery model where health care professionals act as intermediaries. They are also aware of their lack of competency to provide such services. To ensure greater public protection, respondents cite the importance of more stringent regulatory oversight of DTC genetic testing. Whether such an approach is necessary to address the various ethical and social issues raised by nutrigenetic testing remains an open debate.

Abstract
AIMS Our study aimed to assess anticoagulation providers' perception and knowledge of warfarin pharmacogenetic testing, and to identify barriers to using it in their clinical practice. MATERIALS & METHODS An online survey that included 5 perception and 5 knowledge questions about the testing was conducted on anticoagulation providers in North America. Participants were also asked to rank the three most significant barriers to using it. RESULTS The survey response rate was 22%. Over 40% of 448 providers participating in the study were undecided about the testing's potential clinical benefits. On average, providers correctly answered 2 out of 5 knowledge questions. Self confidence in interpreting test results significantly predicted the providers' accuracy of the interpretation. The top three barriers were inadequate literature evidence, testing's impracticality and unproven applicability. CONCLUSION Most of the providers did not respond to the survey. Our study suggests inadequate literature evidence influences providers' perception and their use of the testing. In addition, provider education on warfarin pharmacogenetics may be necessary for testing's widespread use.

Abstract
Individuals with a family history of cancer are at elevated risk for the disease, and web-based tools are available to assist in assessing risk. Preferences for a potential campaign to promote awareness of the role of family history in cancer risk were sought, guided by McGuire's Input-Output Persuasion Model. A randomized telephone survey administered to five underserved communities assessed potential campaign messages, channels, sources, receivers, and destinations and use of the Internet (n = 101). Information sources sought about hereditary cancer and their predictors were assessed. Nearly half of the sample was African American and had annual income below $25,000. Most (59%) had Internet access at home. Few differences emerged as a function of race (African American vs. Other). The Internet was the most common (43%) first source sought for hereditary cancer information, followed by physicians (23%). In univariate multinomial logistic regression models, those with a high school education or more and those with greater family history (trend) were more likely than those without to choose the Internet as their first source of information over physicians. Our survey provided a wealth of information for understanding how to best launch our family history cancer risk communication campaign. Education level affected information seeking, and efforts are under way to lessen this potential barrier.

Abstract
Given the ethical controversies concerning HIV vaccine trials (HVTs), we aimed to understand through an exploratory study how members of institutional review boards (IRBs) in the United States (US) and research ethics committees (RECs) in South Africa (SA) view issues concerning the process and content of reviews of these studies. We mailed packets of 20 questionnaires to 12 US IRB chairs and administrators and seven REC chairs to distribute to their members. We received 113 questionnaires (76 from the US and 37 from SA). In both countries, members tended to be white males with advanced academic degrees. Compared to the US, SA members called for 'major changes' in HVT protocols more frequently (p = 0.004), and were less likely to think that HVT participants understood risks and benefits (p = 0.033) or informed consent forms (p = 0.000). In both countries, members were divided on several critical issues (e.g. the minimum standard for treatment for HVT participants who became infected during the HVT), but agreed that they needed more training. Of the SA respondents, 40% reported that they were 'self-taught' in ethics. This study, the first we know of to offer quantitative data comparing US vs. non-US IRBs/RECs, thus suggests key similarities and differences (e.g. compared to SA respondents, US respondents appeared to overestimate participants' understanding of informed consent), along with needs for education. These initial exploratory data in this area have important implications for IRBs, RECs, policy-makers and scholars concerning future practice, training, policy, and investigations in research ethics, and prevention and treatment of HIV and other diseases in the developing world and elsewhere.

Abstract
CONTEXT Challenges to the identification of hereditary cancer in primary care may be more pronounced in rural Appalachia, a medically underserved region. PURPOSE To examine primary care physicians' identification of hereditary cancers. METHODS A cross-sectional survey was mailed to family physicians in the midwestern and southeastern United States, stratified by rural/non-rural and Appalachian/non-Appalachian practice location (n = 176). Identification of hereditary breast-ovarian cancer (BRCA1/2), hereditary non-polyposis colon cancer (HNPCC), and other hereditary cancers was assessed. FINDINGS Less than half of physicians (45%) reported having patients with cancer genetic testing. Most (70%) correctly identified the BRCA1/2-relevant scenario; 49% correctly identified the HNPCC-relevant scenario. Factor analysis of psychosocial variables revealed 2 factors: Confidence (knowledge, comfort, confidence) and importance (responsible, important, effective, need) of identifying hereditary cancer. Greater confidence was associated with use of 3 generation pedigree in taking family history. Greater knowledge and access to genetic services were associated with use of genetic testing. More recent graduation year, greater knowledge, and greater confidence were associated with identifying the BRCA1/2-relevant scenario. Greater knowledge and confidence were associated with identifying the HNPCC-relevant scenario. CONCLUSIONS Though rural Appalachian physicians do not differ in ability to identify high risk individuals, access barriers may exist for genetic testing. Interventions are needed to boost physician confidence in identifying hereditary cancer and to improve availability and awareness of availability of genetic services.

Abstract
Emerging pharmacogenetics research may improve clinical outcomes for common complex conditions typically treated in primary care settings. Physicians' willingness to offer genetically-tailored treatments to their patients will be critical to realizing this potential. According to recent research, it is likely that genotypes used to tailor smoking will have pleiotropic associations with other addictions and diseases, and may have different frequencies across populations. These additional features may pose an additional barrier to adoption. To assess physicians' willingness to offer a new test to individually tailor smoking treatment according to specific test characteristics, we conducted a national mailed survey of 2,000 U.S. primary care physicians (response rate: 62.3%). Physicians responded to a baseline scenario describing a new test to tailor smoking treatment, and three additional scenarios describing specific test characteristics based on published research; there was random assignment to one of two survey conditions in which the test was described as a genetic or non-genetic test. Our findings indicate physicians' self-reported likelihood (0-100 scale) that they would offer a new test to tailor smoking cessation treatment ranged from 69%-78% across all scenarios. Relative to baseline scenario responses, physicians were significantly less likely to offer the test when informed that the same genotypes assessed for treatment tailoring: (1) may also identify individuals predisposed to become addicted to nicotine (p<.001), (2) differ in frequency by race (p<.004), and (3) may have associations with other conditions (e.g., alcohol and cocaine addiction, attention deficit hyperactivity disorder ADHD and Tourette Syndrome) (p<.01). Describing a new test to individually tailor smoking treatment as a "genetic" versus non-genetic test significantly reduced physicians' likelihood of offering the test across all scenarios, regardless of specific test characteristics (p<.0007). Effective education of primary care physicians will be critical to successful integration of promising new pharmacogenetic treatment strategies for smoking.

Abstract
This article examines the impact of providing personalized familial cancer risk assessments with the Jameslink Cancer Risk Assessment Tool. Users of the Jameslink (N = 166) at eight community health fairs completed a survey including demographic, psychosocial and behavioral variables to better understand responses to the Jameslink. No differences were found between whites and those of other races for variables of interest, indicating suitability of the Jameslink for diverse populations. Those with higher Jameslink-assessed risk had higher perceived risk of cancer. Approximately half (53.8%) reported that they would speak to their physician about their Jameslink-assessed risk. A regression found Jameslink-assessed risk, cancer worry, and perceived risk of cancer predicted intentions to speak to a physician about their risk. In addition, open-ended data provided suggestions to improve the Jameslink. Changes in content and format were suggested; however most were happy with the program and encouraged its promotion. The lack of findings for differences as a function of race bolsters the use of computerized Cancer Risk Assessment Tools in diverse communities. The positive feedback of users and the close association between cancer risk assessment, perceived risk, and intention to speak to a physician are supportive of continued use and development of Cancer Risk Assessment Tools in the community to promote awareness of cancer risk.

Abstract
Several companies utilize direct-to-consumer (DTC) advertising for genetic tests and some, but not all, bypass clinician involvement by offering DTC purchase of the tests. This article examines how DTC marketing strategies may affect genetic counselors, using available cardiovascular disease susceptibility tests as an illustration. The interpretation of these tests is complex and includes consideration of clinical validity and utility, and the further complications of gene-environment interactions and pleiotropy. Although it is unclear to what extent genetic counselors will encounter clients who have been exposed to DTC marketing strategies, these strategies may influence genetic counseling interactions if they produce directed interest in specific tests and unrealistic expectations for the tests' capacity to predict disease. Often, a client's concern about risk for cardiovascular diseases is best addressed by established clinical tests and a family history assessment. Ethical dilemmas may arise for genetic counselors who consider whether to accept clients who request test interpretation or to order DTC-advertised tests that require a clinician's authorization. Genetic counselors' obligations to care for clients extend to interpreting DTC tests, although this obligation may be fulfilled by referral or consultation with specialists. Genetic counselors do not have an obligation to order DTC-advertised tests that have minimal clinical validity and utility at a client's request. This can be a justified restriction on autonomy based on consideration of risks to the client, the costs, and the implications for society.

Abstract
PURPOSE Little is known about physician's knowledge of, and attitudes toward genetics in sub-Saharan Africa. METHODS Survey of 101 pre-clinical, 95 clinical medical students, and 110 physicians, in Cameroon. RESULTS The awareness of DNA diagnosis was poor: 0, 2.2, and 1.2%, respectively, for sickle cell anemia. The majority of the respondents considered genetic counseling as indispensable (97.6, 98.9 and 100%); and prenatal diagnosis as acceptable. The acceptance of medical abortion increased with the level of medical education (62.6, 74.7 and 90.7%). Sickle cell anemia was considered as a "serious disease" by a greater majority of respondents than Down syndrome (P < 0.001). But, in all three groups, the acceptance of termination of affected pregnancy "if the respondent's own child was affected" was lower for sickle cell anemia than Down syndrome (22.4 versus 40.2%, 10.8 versus 29.3% and 36.1 versus 70.4%). CONCLUSIONS The data suggest a poor knowledge of genetic tests among medical students and physicians. This cohort appears to accept the principles of medical genetics. Our data emphasized a need to introduce genetics and to develop research on its ethical and social implications in Cameroon.

Abstract
INTRODUCTION The integration of pharmacogenetic testing into routine care will, in part, depend upon the patients' and physicians' acceptance of these tests. Empirical data regarding patients' and physicians' views on pharmacogenetic testing are lacking. OBJECTIVES To explore patients' and physicians' perspectives on the potential implications of pharmacogenetic testing, particularly focusing on asthma, and to analyze the possible determinants of their expectations, hopes and fears. METHODS We conducted telephone interviews with patients with asthma or chronic obstructive pulmonary disease taking part in a larger pharmacogenetic study, in addition to general practitioners (GPs) from a different region in Germany. A total of 328 patients and 378 GPs were invited to participate. Determinants of their attitudes toward pharmacogenetic testing were assessed using logistic regression analysis. RESULTS Informed consent to participate in this study was given by 196 patients (60%) and 106 GPs (28%). Most patients (96%) and physicians (52%) appreciated the availability of pharmacogenetic tests for a disease such as asthma. Approximately a third of the patients worried about potential unfavorable test results (35%) and violation of privacy (36%). Female patients were more likely to have a fearful attitude (odds ratio [OR]=2.85; 95% confidence interval [CI]=1.58-5.12). Younger patients were generally more likely to be hopeful about the usefulness of pharmacogenetic testing (OR=2.12; CI=1.01-4.46). The GPs' concerns were mainly related to the possibility that patients might either be put under pressure to be tested (72%) or be disadvantaged at private health insurance agencies (61%). The nature of the responsible institution, the clarity of the research aim and explicit informed consent from patients influenced a physicians' decision regarding whether to support a pharmacogenetic study. CONCLUSION The concerns of patients and GPs differ somewhat with respect to negative psychosocial consequences, discrimination or violation of privacy. Development of information for physicians and patients would be helpful in preventing unrealistic fears or hopes.

Abstract
This article discusses genetics-related policy issues that have an impact on health care systems, health care providers, and their patients: privacy, mass screening, family screening, and knowledge dissemination. Access, cost, and ethical implications are important discussant points for each of these genetic-related policy issues. Embedded in the issue of privacy are concerns of insurability, confidentiality, and discrimination. The public health policy implications related to mass screening programs include efficacy of the screening tests, availability of primary and secondary interventions, access, costs, and program evaluation. Policy issues for family screening are similar to mass screening, with added concerns about privacy and availability of adequate resources, including health care providers and counselors trained in genetics. Knowledge dissemination is critical to maintaining currency of clinical information and applications of genetic technologies and treatments. As genetic information expands, the need for knowledge dissemination will increase. The importance of advanced practice nurses' involvement in these policy issues is discussed.

Abstract
As genetic testing for BRCA1 and BRCA2 (BRCA1/2) mutations is increasingly integrated into the clinical management of high-risk women, it will be important to understand barriers and motivations for genetic counseling among women from underserved minority groups to ensure equitable access to these services. Therefore, the purpose of this review was to synthesize literature on knowledge and attitudes about genetic counseling and testing for inherited breast cancer risk in African Americans. We also review studies that evaluated genetic testing intentions in this population. We conducted a search of the PubMed database to identify studies related to BRCA1/2 testing in African Americans that were published between 1995 and 2003. Overall, studies have evaluated ethnic differences in knowledge and attitudes about genetic testing or have compared African American and Caucasian women in terms of genetic testing intentions. These studies have shown that knowledge about breast cancer genetics and exposure to information about the availability of testing is low among African Americans, whereas expectations about the benefits of genetic testing are endorsed highly. However, much less is known about the psychological and behavioral impact of genetic testing for BRCA1/2 mutations in African Americans. Additional research is needed to understand barriers and motivations for participating in genetic testing for inherited cancer risk in African Americans. The lack of studies on psychological functioning, cancer surveillance, and preventive behaviors following testing is a significant void; however, for these studies to be conducted, greater access to genetic counseling and testing in African Americans will be needed.

Abstract
Primary care providers (PCPs) are believed to be the professionals who, in the near future, will be responsible for incorporating genomic medicine (GM) into primary care. Given the dearth of empirical data describing PCPs' beliefs about GM and the relationship between beliefs and the incorporation of GM into practice, this study assessed whether (and to what extent) PCPs' perceptions of GM as an innovation influence their likelihood of adopting this innovation into primary care. The study utilized diffusion of innovations theory as a framework. A state-wide representative sample of PCPs practicing in Texas responded to a mailed survey. The survey measured PCPs' perceptions of five characteristics of GM as an innovation. Findings suggest that among the five characteristics examined GM's relative advantage, compatibility with current practice, its complexity, and observability were the strongest predictors of likelihood to adopt GM tasks into primary care practice.

Abstract
Knowledge of the opinions of physicians with regard to preconceptional cystic fibrosis (CF) carrier screening and the possible factors that are associated with their opinions is important for the implementation of such a screening program. Data were obtained from a study in which genetic knowledge, opinions with regard to genetic testing and related skills were investigated. A questionnaire, developed and used by American researchers, was adapted to the Dutch health care situation, and sent to randomly selected general practitioners (GPs) (n = 200), gynecologists (GYNs) (n = 300), and pediatricians (PEDs) (n = 265). In this part of the study, their opinions with regard to genetic preconceptional CF carrier screening in different situations were assessed. The response rate for the GPs, GYNs, and PEDs was 64%, 69%, and 72%, respectively. In total, 63% of the GPs, 69% of the GYNs and 72% of the PEDs supported preconceptional CF carrier testing if a couple requested a test. Sixteen percent, 19% and 25%, respectively, were in favor of actively offering a test with 95% test sensitivity to all couples who were planning a pregnancy. A positive opinion on preconceptional CF carrier screening was associated with the following variables: "considering the test sensitivity as less important" (GPs, GYNs), "high perceived risk of having a child with CF" (GYNs), "providing genetic counselling in their own practice" (PEDs) and "reassurance when both partners test negative" (PEDs). Physicians are sympathetic toward preconceptional CF carrier screening if the couples themselves request a test. Physicians had reservations about routinely offering a CF carrier test.

Abstract
Primary care physicians (PCPs) are assuming greater roles in cancer risk assessment and susceptibility testing of patients. The objective of this study was to assess the beliefs and practices of PCPs relative to genetic susceptibility testing for cancer. A cross-sectional survey was mailed to 726 PCPs in community-based practices in southeastern Pennsylvania and southern New Jersey. Data were collected on physician background, cognitive and psychosocial factors, practice environment, and patient factors. The main outcome measure was physician self-reported recommendation or referral of patients for cancer genetic susceptibility testing in a 12-month period prior to the survey. Of those surveyed, 475 (65%) PCPs responded. Complete survey data were available for 433 PCPs. Multivariable analyses show that factors positively associated with PCP recommendation/referral included: patient inquiry about their need for genetic testing for cancer (p < 0.001); PCP belief that patient age is the best predictor of cancer risk (p = 0.01); PCP self-reported frequency of collecting patient diet information (p = 0.01) and medical history information (p = 0.01); and PCP participation in an integrated health system (p = 0.01). PCP use of cancer genetic susceptibility testing may be influenced by patient inquiry, provider beliefs about factors that affect cancer risk, provider collection of risk-assessment data, and provider practice environment.

Abstract
After the announcement that sequencing of the human genome was nearly complete, media coverage was extensive. In light of ample evidence that the media are a primary source of health and science information, even for health professionals, media portrayals are often inaccurate or misleading, and discoveries that emanate from sequencing the human genome are likely to influence future health care, it is important to assess physicians' interpretations of media coverage about the human genome announcement. This paper describes the reactions of a sample of new physicians in the United States to this announcement, as well as the content of the stories they read or heard. Semi-structured surveys were distributed to all incoming houseofficers during Orientation at one major academic medical center. Eighty-one percent of 190 houseofficers returned a survey; 123 completed surveys were analyzed. Fifty-four percent of respondents thought the media message was only positive and 21% thought it was negative or mixed. Participants who reported radio as their media source were less likely to recall positive messages (p<0.05). Sixty-five percent and 76%, respectively, had positive perceptions of the impact of the accomplishment on people and on the medical profession. Overall, 48% were enthusiastic and 52% were guarded about the accomplishment. Enthusiasm was related to being an adult primary care houseofficer (p=0.07) or to having heard about it on television or in the newspaper (p<0.05). Of the 36 stories analyzed, newspaper and television reports focused more on medical implications and radio reports focused more on ethical issues. The degree of enthusiasm about the accomplishment reflects the content of the media coverage, and, at least for adult primary care houseofficers, probably reflects the increasing relevance of genetic discoveries to medical practice. Since physicians obtain much of their health and science information from the media, they can play an instrumental role in helping their patients interpret media coverage of advances in genetics and their impact on health care. However, this will require that physicians develop an appreciation of the newsmaking process, and how subtle interactions between politics, the media and science influence the "framing" of media coverage.

Abstract
PURPOSE To investigate whether the importance family physicians place on familial cancer-risk screening is influenced by expectations for the motivational impact of a high-risk genetic test result. METHODS Mailed survey of the Massachusetts Academy of Family Physicians. RESULTS Respondents expected patients would increase pursuit of screening for cancer (99.6%) and other diseases (89.9%), quit smoking (93.6%), and improve diet/exercise (92.5%). The degree of motivational effect was significantly related to the importance they place on screening. CONCLUSIONS Family physicians believe that a high-risk cancer genetic-test result would motivate their patients to pursue risk-reduction behavior, and this belief is related to the importance they place on screening their patients for an inherited risk of cancer.

Abstract
BACKGROUND In many countries, GPs play a key role in the referral to other medical specialists. Referral for reproductive genetic counselling during a pregnancy of women with a genetic risk factor already present before pregnancy has many disadvantages. Nevertheless, some 10-20% of the counsellees who attend a Department of Clinical Genetics for the first time are pregnant. OBJECTIVES We aimed to explore the role of the GP in referring women for genetic counselling during, instead of before a pregnancy. METHOD The GPs of 100 pregnant women who received genetic counselling were invited to participate in the study and asked to complete a questionnaire. The topics were: initiation and discussion of aspects of referral to the Department of Clinical Genetics; reasons for the referral during, instead of before a pregnancy; knowledge of genetic counselling; attitudes towards genetic counselling before a pregnancy; and attitudes towards abortion. RESULTS To our surprise, 29% of the GPs indicated that they had not been involved in the referral to the Department of Clinical Genetics at all. Furthermore, the referral was initiated by the patient herself in most cases (40%) and by the GPs in 31% of the cases. Of the GPs who were involved in the referral, most of them (79%) talked to their patients to different extents about what to expect from their visit to the Department of Clinical Genetics; however, potential choices after an adverse outcome at prenatal diagnosis were discussed less often (60%). The main reason for referring the patient during, instead of before her pregnancy was because the GP was unaware of a potential risk factor before pregnancy (71%) and, consequently, never had a chance to talk about a referral before (71%). Other reasons for referral during pregnancy mentioned by the GPs were reassuring the patient about the health of her unborn child (32%) and the wish of the patient to be referred during pregnancy (31%). GPs considered their knowledge of clinical genetics to be limited (mean score 5, on a scale from 0 to 10). The majority of the GPs were in favour of genetic counselling taking place before, instead of during pregnancy, and they had no great objections to abortion. CONCLUSIONS During pregnancy, the gatekeeper function of the GP in the referral for genetic counselling is undermined. Limited alertness and awareness among GPs about genetic risk factors in their patients played a major role in this undermined function and in the less appropriate timing of referral. Neither insufficient knowledge nor barriers to acceptance explained this lack of alertness and awareness. We advocate the implementation of routine family history taking in general practice.

Abstract
PURPOSE To assess nongeneticist physicians' knowledge and experience with BRCA1/2 testing. METHODS In 1998, 2250 internists, obstetrician-gynecologists (Ob-Gyns), and oncologists practicing in Pennsylvania, Maryland, Massachusetts, New York, or New Jersey were surveyed. RESULTS Forty percent responded. Only 13% of internists, 21% of Ob-Gyns, and 40% of oncologists correctly answered all four knowledge questions about genetic aspects of breast cancer and testing for it. Knowledge was associated with discussing or ordering only among oncologists. CONCLUSION Despite deficiencies in their knowledge about the genetic aspects of breast cancer, many nongeneticist physicians have discussed testing and some have ordered testing.

Abstract
PURPOSE The purpose of this literature review is to report primary care physicians' perceived barriers concerning the provision of genetic services. METHODS Sixty-eight papers were identified in six electronic databases. Only publications classified as empirical studies (N = 18) were included in this review. RESULTS Barriers identified most frequently in reviewed studies were inadequate knowledge of basic genetics, lack of detailed or updated family histories, lack of confidence, and lack of referral guidelines. CONCLUSION Although many primary care physicians perceive genetics as a low practice priority, they do report a need for educational programs in genetics, informational resources, and referral guidelines.

Abstract
In a survey we investigated whether gynecologists are sufficiently knowledgeable to perform genetic counseling. It provides information for the development and evaluation of a counseling manual for professionals in primary health care. The members of the sample, consisting of 529 gynecologists in northern Germany, were mailed a questionnaire concerning their knowledge of and attitudes towards genetic counseling and testing for hereditary breast and ovarian cancer (HBOC). The response rate was 32.5% (n = 172). The majority of the respondents (82%) have received requests from patients for genetic testing. Most would offer basic genetic counseling to their patients, 66% feel knowledgeable enough to do so. Physicians set high value on communicating clinical management options, but also consider psychosocial aspects to be important. The results suggest that HBOC genetics play a noticeable role in the practice of gynecology in Germany. There is consensus about the need for further educational training to deal with cancer genetics in physicians' daily practice.

Abstract
PURPOSE The increasing use of the Internet to obtain genetics information and to order medical services without a prescription, combined with a rise in direct-to-consumer marketing for genetic testing, suggests the potential for the Internet to be used to sell genetic services. METHODS A systematic World Wide Web search was conducted in May 2002 to assess the availability of genetic services sold directly to consumers on the Internet. RESULTS Out of 105 sites that offered genetic services directly, most offered non-health-related services, including parentage confirmation testing (83%), identity testing (56%), and DNA banking (24%); however, health-related genetic tests were offered through 14 sites (13%). The health-related genetic tests available ranged from standard tests, such as hemochromatosis and cystic fibrosis, to more unconventional tests related to nutrition, behavior, and aging. Of these 14 sites, 5 described risks associated with the genetic services and 6 described the availability of counseling. CONCLUSIONS The availability of direct sales of health-related genetic tests creates the potential for inadequate pretest decision making, misunderstanding test results, and access to tests of questionable clinical value.

Abstract
PURPOSE Because of the explosion of genetic information resulting from the Human Genome Project and other developments in genetics and genetic technologies, primary care practitioners in Australia will be expected to have a much greater role in the practice of genetic medicine; however, little is published regarding their knowledge and attitudes to genetics, technologies, or genetics education. This study aimed to determine the genetics knowledge and educational needs of general practitioners (GPs) in Victoria, Australia, and their experiences in dealing with genetics in their practices. METHODS Qualitative research methods were used primarily to obtain data from focus groups, interviews, and a limited survey. RESULTS GPs believed their knowledge of genetics was poor and they felt inadequately prepared to manage patients with genetic conditions. They identified testing and counseling as areas that particularly needed strengthening. CONCLUSION These data, together with GPs' suggestions about educational strategies, are essential for developing appropriate genetics education programs and resources that are relevant for Australian health care.
