Education and Counseling About Risk/Risk Communication

Specific clinical programs for risk management may be offered to persons with an increased genetic risk of cancer. These programs may differ from those offered to persons of average risk in several ways: screening may be initiated at an earlier age or involve shorter screening intervals; screening strategies not in routine use, such as screening for ovarian cancer, may be offered; and interventions to reduce cancer risk, such as risk-reducing surgery, may be offered. Current recommendations are summarized in the PDQ summaries addressing the genetics of specific cancers.
The goal of genetic education and counseling is to help individuals understand their personal risk status, their options for cancer risk management, and to explore feelings regarding their personal risk status. Counseling focuses on obtaining and giving information, promoting autonomous decision making, and facilitating informed consent if genetic testing is pursued.
Optimally, education and counseling about cancer risk includes providing the following information:
  • Purpose, strengths, and limitations of cancer risk assessment.
  • Basic genetics and patterns of inheritance.
  • Genetic basis of cancer.
  • Clinical features of relevant hereditary cancer syndromes.
  • Evidence of a hereditary cancer syndrome from the consultand's personal and family history.
  • Options for clarifying cancer risk, including genetic testing, if indicated.
  • Options available for risk management, including data (or lack of data) on the efficacy of different measures for early detection and risk reduction.
  • Signs and symptoms of cancer.
When a clinically valid genetic test is available, education and counseling for genetic testing typically includes the following:
  • Risk of having a pathogenic variant and patterns of transmission.
  • Alternatives to genetic testing.
  • Risks, benefits and limitations of genetic testing, including psychological and discriminatory risks.
  • Possible test outcomes, including likelihood of uninformative results and identifying variants of uncertain significance.
  • Sensitivity of the genetic test, including the techniques utilized to perform the test and their associated limitations.
  • Health care management options based on possible test results.
  • Implications for children and other family members based on pattern of transmission.
  • Dissemination of risk and genetic information to family members.
  • Cost associated with testing, counseling, medical management, and options for insurance coverage.
  • How genetic information and genetic test results will be recorded in the medical record.
  • Specimen storage and reuse, if applicable.
If a second session is held to disclose and interpret genetic test results, education and counseling focuses on the following:
  • Interpretation of test results.
  • Discussion of further testing that may clarify risk (e.g., large rearrangement testing and testing the other genes based on the patient's differential cancer syndrome list).
  • Assessment of the emotional and behavioral responses to genetic test results.
  • Recommendations for coping and communication strategies to address issues related to cancer risk.
  • Cancer risk management recommendations.
  • Risk analysis and dissemination of risk results to family members.
The process of counseling may require more than one visit to address medical, genetic testing, and psychosocial support issues. Additional case-related preparation time is spent before and after the consultation sessions to obtain and review medical records, complete case documentation, seek information about differential diagnoses, identify appropriate laboratories for genetic tests, find patient support groups, research resources, and communicate with or refer to other specialists.[1]
Information about inherited risk of cancer is growing rapidly. Many of the issues discussed in a counseling session may need to be revisited as new information emerges. At the end of the counseling process, individuals are typically reminded of the possibility that future research may provide new options and/or new information on risk. Individuals may be advised to check in with the health care provider periodically to determine whether new information is sufficient to merit an additional counseling session. The obligation of health care providers to recontact individuals when new genetic testing or treatment options are available is controversial, and standards have not been established.

Methods of Risk Presentation

The usage of numerical probabilities to communicate risk may overestimate the level of risk certainty, especially when wide confidence intervals exist to the estimates or when the individual may differ in important ways from the sample on which the risk estimate was derived. Also, numbers are often inadequate for expressing gut-level or emotional aspects of risk. Finally, there are wide variations in individuals’ level of understanding of mathematical concepts (i.e., numeracy). For all the above reasons, conveying risk in multiple ways, both numerically and verbally, with discussion of important caveats, may be a useful strategy to increase risk comprehension. The numerical format that facilitates the best understanding is natural frequencies because frequencies include information concerning the denominator, the reference group to which the individual may refer. In general, logarithmic scales are to be avoided.[2] Additionally, important “contextual” risks may be included with the frequency in order to increase risk comprehension; these may include how the person’s risk compares with those who do not have the risk factor in question and the risks associated with common hazards, such as being in a car accident. Additional suggestions include being consistent in risk formats (do not mix odds and percentages), using the same denominator across risk estimates, avoiding decimal points, including base rate information, and providing more explanation if the risk is less than 1%.
The communication of risk may be numerical, verbal, or visual. Use of multiple strategies may increase comprehension and retention of cancer genetic risk information.[2] Recently, use of visual risk communication strategies has increased (e.g., histograms, pie charts, and Venn diagrams). Visual depictions of risk may be very useful in avoiding problems with comprehension of numbers, but research that confirms this is lacking.[3,4] A study published in 2008 examined the use of two different visual aids to communicate breast cancer risk. Women at an increased risk of breast cancer were randomized to receive feedback via a bar graph alone or a bar graph plus a frequency diagram (i.e., highlighted human figures). Results indicate that overall, there were no differences in improved accuracy of risk perception between the two groups, but among those women who inaccurately perceived very high risk at baseline, the group receiving both visual aids showed greater improvement in accuracy.[5]

Risk Communication

The purpose of risk counseling is to provide individuals with accurate information about their risk, help them understand and interpret their risk, assist them as they use this information to make important health care decisions, and help them make the best possible adjustment to their situation. A systematic review of 28 studies that evaluated communication interventions showed that risk communication benefits users cognitively by increasing their knowledge and understanding of risk perception and does not negatively influence affect (anxiety, cancer-related worry, and depression). Risk communication does not appear to result in a change in use of screening practices and tests. Users received the most benefit from an approach utilizing risk communication along with genetic counseling.[6,7] Perceptions of risk are affected by the manner in which risk information is presented, difficulty understanding probability and heredity,[8,9] and other psychological processes on the part of individuals and providers.[10] Risk may be communicated in many ways (e.g., with numbers, words, or graphics; alone or in relation to other risks; as the probability of having an adverse event; in relative or absolute terms; and through combinations of these methods). The way in which risk information is communicated may affect the individual’s perception of the magnitude of that risk. In general, relative risk estimates (e.g., "You have a threefold increased risk of colorectal cancer") are perceived as less informative than absolute risk (e.g., "You have a 25% risk of colorectal cancer") [11] or risk information presented as a ratio (e.g., 1 in 4).[9] A strong preference for having BRCA1/BRCA2 pathogenic variant risk estimates expressed numerically is reported by women considering testing.[12] Individuals associate widely differing quantitative risks with qualitative descriptors of risk such as “rare” or “common.”[13] More research is needed on the best methods of communicating risk in order to help individuals develop an accurate understanding of their cancer risks.

Communication Strategies

Recent descriptive examination of the process of cancer genetic counseling has found that counseling sessions are predominantly focused on the biomedical teaching required to inform clients of their choices and to put genetic findings in perspective but that attention to psychosocial issues does not detract from teaching goals and may enhance satisfaction in clients undergoing counseling. For instance, one study of communication patterns in 167 pretest counseling sessions for BRCA1 found the sessions to have a predominantly biomedical and educational focus;[14] however, this approach was client focused, with the counselor and client contributing equally to the dialogue. These authors note that there was a marked diversity in counselor styles, both between counselors and within different sessions, for each counselor. The finding of a didactic style was corroborated by other researchers who examined observer-rated content checklists and videotape of 51 counseling sessions for breast cancer susceptibility.[15] Of note, genetic counselors seemed to rely on demographic information and breast cancer history to tailor genetic counseling sessions rather than client’s self-reported expectations or psychosocial factors.[16] Concurrent provision of psychosocial and scientific information may be important in reducing worry in the context of counseling about cancer genetics topics.[17] An increasing appreciation of language choices may contribute to enhanced understanding and reduced anxiety levels in the session; for example, it was noted that patients may appreciate synonymic choices for the word “mutation,” such as “altered gene”.[18] Some authors have published recommendations for cultural tailoring of educational materials for the African-American population, such as a large flip chart, including the use of simple language and pictures, culturally identifiable images (e.g., spiritual symbols and tribal patterns), bright colors, and humor.[19]
Studies have examined novel channels to communicate genetic cancer risk information, deliver psychosocial support, and standardize the genetic counseling process for individuals at increased risk of cancer.[20-27] Much of this literature has attempted to make the genetic counseling session more efficient or to limit the need for the counselor to address basic genetic principles in the session to free up time for the client’s personal and emotional concerns about his or her risk. For example, the receipt of genetic feedback for BRCA1/BRCA2 and mismatch repair gene testing by letter, rather than a face-to-face genetic counseling feedback session, has been investigated.[28] Other modalities include the development of patient assessments or checklists, CD-ROM programs, and interactive computer programs.
Patient assessments or checklists have been developed to facilitate coverage of important areas in the counseling session. One study assessed patients’ psychosocial needs before a hereditary cancer counseling session to determine the assessment’s effect on the session.[29] A total of 246 participants from two familial cancer clinics were randomly assigned to either an intervention arm in which the counselor received assessment results or a usual care control arm. Study results demonstrated that psychosocial concerns were discussed more frequently among intervention participants than among controls, without affecting session length. Moreover, cancer worry and psychological distress were significantly lower for intervention versus control participants 4 weeks after the counseling session.
A second study compared a feedback checklist completed by 197 women attending a high-risk breast clinic prior to the counseling session to convey prior genetic knowledge and misconceptions to aid the counselor in tailoring the session for that client.[22] The use of the feedback checklist led to gains in knowledge from the counseling session but did not reduce genetic counseling time, perhaps because the genetic counselor chose to spend time discussing topics such as psychosocial issues. Use of the checklist did decrease the time spent with the medical oncologist, however. The feedback checklist was compared with a CD-ROM that outlined basic genetic concepts and the benefits and limitations of testing and found that those viewing the CD-ROM spent less time with counselors and were less likely to choose to undergo genetic testing. The CD-ROM did not lead to increased knowledge of genetic concepts, as did use of the checklist.
A prospective study evaluated the effects of a CD-ROM decisional support aid for microsatellite instability (MSI) tumor testing in 239 colorectal cancer patients who met the revised Bethesda criteria but who did not meet the Amsterdam criteria.[30] The study also tested a theoretical model of factors influencing decisional conflict surrounding decisions to pursue MSI tumor testing. Within the study, half of the sample was randomly assigned to receive a brief description of MSI testing within the clinical encounter, and the other half was provided the CD-ROM decisional support aid in addition to the brief description. The CD-ROM and brief description intervention increased knowledge about MSI testing more than the brief description alone did. As a result, decisional conflict decreased because participants felt more prepared to make a decision about the test and had increased perceived benefits of MSI testing.
Other innovative strategies include educational materials and interactive computer technology. In one study, a 13-page color communication aid using a diverse format for conveying risk, including graphic representations and verbal descriptions, was developed.[23] The authors evaluated the influence of the communication aid in 27 women at high risk of a BRCA1/BRCA2 pathogenic variant and compared those who had read the aid to a comparison sample of 107 women who received standard genetic counseling. Improvements in genetic knowledge and accuracy of risk perception were documented in those who had read the aid, with no differences in anxiety or depression between groups. Personalized, interactive electronic materials have also been developed to aid in genetic education and counseling.[24,25] In one study, an interactive computer education program available prior to the genetic counseling session was compared with genetic counseling alone in women undergoing counseling for BRCA1/BRCA2 testing.[25] Use of the computer program prior to genetic counseling reduced face-time with the genetic counselor, particularly for those at lower risk of a BRCA1/BRCA2 pathogenic variant. Many of the counselors reported that their client’s use of the computer program allowed them to be more efficient and to reallocate time spent in the sessions to clients’ unique concerns.
Videoconferencing is an innovative strategy to facilitate genetic counseling sessions with clients who cannot travel to specialized clinic settings. In 37 individuals in the United Kingdom, real-time video conferencing was compared with face-to-face counseling sessions; both methods were found to improve knowledge and reduce anxiety levels.[26] Similarly, teleconferencing sessions, in which the client and genetic specialists were able to talk with each other in real time, were used in rural Maine communities [27] in the pediatric context to convey genetic information and findings for developmental delays and were found to be comparable to in-person consultations in terms of decision-making confidence and satisfaction with the consultations. An Australian study compared the experiences of 106 women who received hereditary breast and ovarian cancer genetic counseling via videoconferencing with the experiences of 89 women who received counseling face to face. Pre- and 1-month postcounseling assessments revealed no significant differences in knowledge gains, satisfaction, cancer-specific anxiety, generalized anxiety, depression, and perceived empathy of the genetic counselor.[31]

Ethical, Legal, and Social Implications

Having an understanding of the ethical, legal, and social implications (ELSI) regarding cancer genetic testing may influence the clinician’s response to the complex questions and issues that may arise during the process of risk assessment and counseling. This section discusses biomedical ethics codes, legal and social issues relevant to privacy, and fair use in the interpretation of genetic information. In order to integrate the different perspectives of bioethics, law, and psychosocial influences, case scenarios are offered to illustrate dilemmas encountered in the clinical setting. (Refer to the Determining the Test to Be Usedsection of this summary for more information about the regulation of genetic tests.)

Bioethical Issues in Cancer Genetic Testing

Bioethical tenets can guide health care providers in dealing with the complex issues surrounding predictive testing for hereditary cancer. The tenets of beneficence, nonmaleficence, autonomy, and justice are part of a framework needed to balance the complex and potentially conflicting factors surrounding a clinician’s role in respecting privacy, confidentiality and fair use of genetic information obtained from cancer genetic testing.

Beneficence

The concept of beneficence dictates that the primary goal of medical care is to provide benefit through appropriate health care.[1] In the field of oncology, this translates into using early detection and effective treatment protocols to improve outcomes. Providing beneficent care may go beyond medical outcomes of treatment to encompass the patient’s life circumstances, expectations, and values.[1] Consideration of the patient’s psychological and emotional ability to handle the testing and results disclosure process can help avoid doing harm.[2] (Refer to the Psychological Impact of Genetic Testing/Test Results on the Individual section of this summary for more information.)

Nonmaleficence

Nonmaleficence is the bioethical code that directs health care providers to do no harm, inclusive of physical and emotional harm, and acknowledges that medical care involves risks and benefits.[1] Particular to the field of oncology, adherence to this construct includes taking measures to minimize the adverse effects of cancer prevention, treatment, and control. This may encompass taking precautionary measures to prevent inadvertent disclosure of sensitive information.[2]

Autonomy

Autonomous decision making respects individual preferences by incorporating informed consent and education.[1] Individuals have the right to be informed about the risks and benefits of genetic testing and to freely choose or decline testing for themselves. Additionally, it is beneficial to consider the sociocultural context and family dynamics to ensure medical decision making takes places without coercion or interference.[1]

Justice

Justice refers to the equitable distribution of the benefits and risks of health care.[1] A goal in oncology is ensuring access to cancer genetic services. The availability of predictive genetic testing should not be dependent on ethnic background, geographical location, or ability to pay. Genetic discrimination should not be a result of predictive testing.[2] Equitable distribution balances individual rights with responsibilities of community membership.[1]

Privacy and Confidentiality: Disclosure of Patient’s Genetic Information

A strong provider-patient relationship is founded on respect for the patient’s privacy and confidentiality; therefore, protecting the patient’s personal information from third parties is key to building trust.[2,3] Predictive testing for cancer susceptibility presents a challenge because of the hereditary nature of the diseases being tested and the implications of genetic risk for family members. Physicians are faced with a duty to warn or to act to prevent foreseeable harm.[4] One practical suggestion for facilitating family-based communication is providing patients with education and information materials to facilitate disease susceptibility discussions with family members.[1] The next section discusses the legal, legislative, and ethical basis for balancing patient confidentiality with duty to warn.

Disclosure in research

Privacy and confidentiality also applies to research, such as population screening for genetic diseases. The U.S. Department of Health and Human Services authorizes the use of Certificates of Confidentiality to researchers.[5] This certificate, issued by the National Institutes of Health, protects the researcher from having to reveal the identity of any research subject “in any Federal, State, or local civil, criminal, administrative, legislative, or other proceedings.” The protections offered by the certificate of confidentiality are limited to personally identifiable information collected beginning on the date of issuance and ending on the expiration date, which matches the date of study completion. The NIH Office of Extramural Research policy and guidance on Certificates of Confidentiality notes that any personally identifiable information collected during that time interval is protected in perpetuity. In regard to family-based recruitment strategies, the Cancer Genetics Network Bioethics Committee assembled a group of experts to develop recommendations for researchers to use in approaching family members.[6] Due to the wide spectrum of research strategies, there are different levels of concern. Essential to family-based recruitment strategies is informing potential research participants how their personal information was obtained by the researcher, why the researcher is approaching them, what the researcher knows about them, and for what purpose the information will be used, whether or not they decide to participate.[6]

“Duty to warn”: Legal proceedings, federal/state legislation, and recommendations of professional organizations

“Duty to warn” requires balancing the bioethical constructs of beneficence and autonomy with other factors such as case proceedings, legislation, and professional societies’ recommendations. As of September 2008, the National Council of State Legislatures lists the statesExit Disclaimer that have legislation requiring consent to disclose genetic information. The definition of "genetic information" can vary depending on the legal case and the language used in state and federal legislation, and generally includes genetic testing and family history information; however, the definition generally does not apply to current diagnoses. Genetic diagnosis can be done through direct genetic tests for disorders linked to a specific gene and indirect genetic tests for disorders in which the specific genes are not known or there are multiple different genes involved (genetic heterogeneity).[7] There are four state case laws that apply to duty to warn.[8] Two cases deal directly with testing for hereditary cancer predisposition syndromes; one case deals with a psychotherapist's duty to warn a relative of imminent threat, and another with genetic testing as a tool for reproductive decisions. Table 4 summarizes the cases.
Table 4. State Case Laws That Apply to Duty to Warn
State Case LawDescriptionSummary
Tarasoff versus Regents of the University of California [9,10]Establishes moral duty to warn family members of risks unknown to themIn 1976, the California court judged that breach of confidentiality would have been justified in order to warn of a foreseeable and serious harm to an identifiable individual.
Distinct from genetic risk since the pathogenic variantis already present (or absent) in family members
Pate versus Threlkel [8,11,12]Duty to warn family members of hereditary risk of cancer is satisfied by telling the patient to tell his or her familyIn 1995, the Florida court judged that a physician had a duty to warn the patient that her children were at risk of developing thyroid cancer because the disease could have been detected and cured at an earlier stage.
Safer versus Estate of Pack [8,13]Physician must take reasonable steps to warn family members of hereditary risk diseaseIn 1996, a New Jersey appellate court defined a physician’s duty to warn immediate family members of risk of colon cancer; however, the court ruled in favor of the doctor because the patient had undergone rectal screening as a child, which indicated that she had been warned of the risk.
Molloy versus Meier [8,14]Physician’s duty regarding genetic testing and diagnosis of foreseeable disease risk extends beyond the patient to biological parentsIn 2004, a Minnesota Supreme Court held that the physician failed to breach confidentiality to warn of hereditary disease risk because he did not inform parents of the diagnosis of fragile X syndrome in their first child. The parents state that this information would have influenced their reproductive decisions.
At the federal level, there are strict nondisclosure policies governing private health information.[8] The Standards for Privacy of Individually Identifiable Health Information (Privacy Rule), which summarizes the Health Insurance Portability and Accountability Act (HIPAA) of 1996, finds it permissible to disclose health information without consent when the public interest is at risk;[15,16] therefore, under certain conditions, there are exceptions to the nondisclosure policy include the following:
  1. There is serious or imminent threat to the health or safety of a person or the public.
  2. The threat constitutes an imminent, serious threat to an identifiable third party.
  3. The physician has the capacity to avert significant harm.
Professional societies and government advisory agencies have published their different positions and recommendations on communication between a physician and a patient's relatives in regard to disclosure of genetic disease.[4,8,17]
The Council on Ethical and Judicial Affairs of the American Medical AssociationExit Disclaimer (AMA) and the American Society of Clinical Oncology (ASCO) [18,19] encourage discussing the importance of patients sharing genetic information with family members.[4] Specifically, the Council on Ethical and Judicial Affairs of the American Medical AssociationExit Disclaimer states that “Physicians …should identify circumstances under which they would expect patients to notify biological relatives of the availability of information related to risk of disease…(and) physicians should make themselves available to assist patients in communicating with relatives to discuss opportunities for counseling and testing, as appropriate.” ASCO’s position is that providers “should remind patients of the importance of communicating test results to family members… ASCO believes that the cancer care provider’s obligations (if any) to at-risk relatives are best fulfilled by communication of familial risk to the person undergoing testing, emphasizing the importance of sharing this information with family members so that they may also benefit.”[18] These organizations recommend that family members disclose genetic information.
The National Society of Genetic Counselors [20] and the International Society of Nurses in Genetics [21] support the release of any genetic information upon request to third parties including relatives but only with the patient's consent.[4] One of the tenets of genetic counseling is to maintain information received from clients as confidential, unless released by the client or consent for disclosure is provided as required by law.[4,20]
Similar to the Privacy Rule, the U.S. Bioethics Commission,[22] American Society of Human Genetics,[23] and National Human Genome Research Institute (NHGRI) recommend the following guidelines to identify exceptional circumstances under which it is ethically acceptable to breach confidentiality.[4,8]
  1. There is a high likelihood of harm if the relative is not warned.[4,22,23]
  2. The patient, despite encouragement, refuses to inform family members.[4,22,23]
  3. The relative is identifiable.[23]
  4. The harm of nondisclosure is greater than the harm of disclosure.[23]
  5. Current medical technology renders the disease preventable, treatable, or manageable.[23]
  6. Only the information necessary to prevent harm is released.[4,24]
  7. There is no other reasonable way to avert harm.[4]
At an international level, the World Health Organization and World Medical Association have similar guidelines.[4] Additionally, Australia, Canada, Germany, Japan, the Netherlands, and the United Kingdom have guidelines supporting the disclosure of genetic information to relatives under similar exceptional circumstances.[4]

Employment and Insurance Discrimination

Genetic information obtained from genetic susceptibility tests may have medical, economic, and psychosocial implications for the individual tested and his or her family members. The potential for employment and insurance discrimination is a common concern for individuals considering genetic testing.[25,26] However, there is limited documentation of the occurrence of employment and insurance discrimination on the basis of hereditary cancer genetic testing results.
Public awareness of the federal Genetic Information Nondiscrimination Act (GINA) and its protections is limited. In a multistate survey conducted in 2010, more than 80% of respondents indicated that they were unaware of the law.[27] In a 2014 survey of 1,479 U.S. adults, 79% indicated that they were unaware of the law.[28] Of those who were aware of GINA, 44% knew that it protected against health insurance and 33% knew it protected against employment discrimination; 23% incorrectly believed the law protected against life, disability, and long-term insurance discrimination. After reading a description of GINA, 30% of respondents indicated that they were actually more concerned about discrimination [note: The denominator for the latter finding is uncertain]. Although genetic testing has increased since the passage of the law, relatively few cases of discrimination in which GINA’s authority can be tested have been reported.[28]
(Refer to the Informed Consent and Exploration of potential risks, benefits, burdens, and limitations of genetic susceptibility testing subsections of this summary for more information about discrimination issues related to cancer genetics services.)

Legal proceedings, federal/state legislation, and recommendations of professional organizations

A legal case example at the federal district court level involves the Burlington Northern Santa Fe Railroad. The U.S. Equal Employment and Opportunities Commission requested that Burlington Northern Santa Fe Railroad not be allowed to use medical information obtained from genetic tests for employment decisions.[24]
In the last 15 years, state and federal legislation statutes have been developed to prevent the use of genetic information for employment practices, such as hiring, promotion, and salary decisions; and insurance policies, including life and health coverage, by employers, schools, government agencies, and insurers.[12] According to Executive Order 13145, federal departments and agencies are prohibited from discriminating against employees on the basis of genetic test results or information about a request for genetic testing services.[24] Employers and insurers are prohibited from intentionally lowering policy rates by using practices such as screening for individuals who are at risk of becoming ill or dying due to genetic disease susceptibility, such as cancer.[24] Federal laws, including GINA, do not cover employer-provided life and disability; however, some states do have legislation addressing the use of genetic information for life and disability policies. The National Conference of State Legislatures (NCSL) [29,30] summarized current health legislation of the U.S. Congress. Examples of relevant legislation regarding genetic information include, GINA, HIPAA, Americans with Disabilities Act (ADA), and Employee Retirement Income Security Act (ERISA).

Genetic Information Nondiscrimination Act 2008
GINA 2008 protects the provision of health insurance and employment against discrimination based on genetic information as follows:
  • Prohibits access to individuals’ personal genetic information by insurance companies and by employers.[32]
  • Prohibits insurance companies from requesting that applicants for group or individual health coverage plans be subjected to genetic testing or screening and prohibits them from discriminating against health plan applicants based on individual genetic information.[32]
  • Prohibits employers from using genetic information to refuse employment, and prohibits them from collecting employees’ personal genetic information without their explicit consent.[32]
  • Prohibits employment agencies from failing or refusing to refer a candidate on the basis of genetic information.[33]
  • Prohibits labor organizations from refusing membership based on a member's genetic make-up.[33]
  • Does not mandate coverage for medical tests or treatments.[34]
  • Does not prohibit medical underwriting based on current health status.[34]
  • Does not limit a treating health provider, including those employed by or affiliated with health plans, from requesting or notifying individuals about genetic tests.[35]
  • Does not prohibit occupational testing for toxic monitoring programs, employer-sponsored wellness programs, administration of federal and state family and medical leave laws, and certain cases of inadvertent acquisition of genetic information.[36]
GINA amends and/or extends coverage of HIPAA, ADA, and ERISA by including genetic information under medical privacy and confidentiality legislation and employment and insurance determinations.[29] Additionally, with the passage of GINA, researchers and clinicians can encourage participation in clinical trials and appropriate genetic testing knowing that there are federal protections against discrimination based on the results of genetic testing. GINA established the minimum protection level that must be met in all states. However, for states with more robust legislation in place, GINA does not weaken existing protections provided by state law.
However, GINA has several limitations.
  1. GINA does not apply to members of the United States military, to veterans obtaining health care through the Veteran’s Administration, or to the Indian Health Service because the laws amended by GINA do not apply to these groups and programs.
  2. The legislation does not apply to life insurance, long-term care insurance, or disability insurance. Even though GINA does not provide protection for employer-provided disability and life insurance, some states do encompass these arenas in addition to employment, genetic privacy, health insurance, health insurance enforcement, life, disability, and long-term care. NHGRI's Genome Statute and Legislation Databaseprovides a searchable listing of state statutes and bills related to the following topics: direct-to-consumer genetic testing, employment and insurance nondiscrimination, health insurance coverage, privacy, research, and the use of residual newborn screening specimens.
  3. GINA’s employment provisions generally do not apply to employers with fewer than 15 employees.[34]
A study conducted between 2009 and 2010 via a survey posted on the Facing Our Risk of Cancer Empowered (FORCE) website provides insight into consumers' perspectives regarding insurance discrimination based on genetic test results after the passage of GINA. Of the 1,669 participants (69% of whom previously received genetic testing), 53% indicated that they had heard about insurance discrimination based on genetic test results. More than half the sample (54%) reported that they had not heard about GINA before the survey. After being provided with a brief description of GINA as part of the survey process, 60% (n = 886) reported a change in their feelings about genetic testing, with the majority (573 of 886 participants) indicating less concern about health insurance discrimination. Finally, when asked whom they would contact regarding questions about GINA, 38% indicated their health care provider.[37]
Exception to protections against employment and insurance discrimination: Active duty military personnel
GINA and other state and federal protections do not extend to genetic testing of active duty military personnel or genetic information obtained from active duty military personnel.[38] In the military, genetic testing provides medical information that is to be used to protect military personnel from harmful duty or other exposures that could stimulate or aggravate a health problem. For example, use of certain antimalaria medication in individuals with glucose 6-phosphate dehydrogenase deficiency can result in red blood cell rupture. Therefore, some genetic information is critical for maintaining the health and safety of military personnel, given the possible stressful occupational environments they face. In addition, all military personnel provide a DNA sample to be maintained in a repository that can be used for identification purposes.[39]
Results of genetic tests for disease predisposition could influence military eligibility for new enlistments, and for current military personnel, genetic test results could influence worldwide eligibility, assignments, and promotions. For example, a young woman found to carry a BRCA pathogenic variant may not be considered eligible for deployment for 12-15 months because access to recommended health care may not be easily accessible, such as breast MRI, a recommended screening modality for carriers of BRCA pathogenic variants. Active duty military personnel with less than eight years of active duty service are especially vulnerable in the event they become disabled and must go before the medical board to establish benefit eligibility.
In 2006, Department of Defense Instruction Number 1332.38 (DODINST 1332.38) redefined preexisting condition as a result of two cases brought by service members who each had a hereditary condition that presented later in their military careers. The disability instructions state that any injury or disease discovered after a service member enters active duty—with the exception of congenital and hereditary conditions—is presumed to have been incurred in the line of duty. Any hereditary and/or genetic disease shall be presumed to have been incurred prior to entry into active duty. However, DODINST 1332.38 further states that any aggravation of that disease, incurred in the line of duty, beyond that determined to be due to natural progression, shall be deemed service aggravated. As a result of these two cases, the 8-year active duty service limit was established. This means that after 8 or more years of military service, the natural progression of a genetic condition would be deemed aggravated by military service. Therefore, until late 2008, the presence of a congenital or hereditary condition would not be considered a preexisting condition in disability decision making for those with 8 or more years of service.
In October 2008, in response to the National Defense Authorization Act of 2008 (NDAA) Title XVI: “Wounded Warrior Matters,” a policy memorandum was issued providing supplemental and clarifying guidance on implementing disability-related provisions, including new language related to hereditary or genetic diseases. The policy memorandum states, “Any hereditary or genetic disease shall be evaluated to determine whether clear and unmistakable evidence demonstrates that the disability existed before the Service member’s entrance on active duty and was not aggravated by military service. However, even if the conclusion is that the disability was incurred prior to entry on active duty, any aggravation of that disease, incurred while the member is entitled to basic pay, beyond that determined to be due to natural progression shall be determined to be service aggravated.” The interpretation of this policy is uncertain at this time.[39]
Case scenarios involving ELSI issues in cancer genetic testing
There are multiple psychosocial, ethical, and legal issues to consider in cancer genetic testing. Genetic tests for germline pathogenic variants have social and family implications. In addition to prevention and surveillance options, genetic testing should be offered in conjunction with genetic education and counseling.[18,19] A comprehensive strategy for dealing with ethical dilemmas can incorporate a shared approach to decision making, including open discussion, planning, and involvement of the family.[5] To integrate the different perspectives of bioethics, law, and psychosocial influences, the following scenarios can help health care providers become familiar with commonly encountered dilemmas; it is imperative, however, that the clinician evaluate each patient and his or her situation on a case-by-case basis. These case scenarios were adopted from “Counseling about Cancer: Strategies for Genetic Counseling;” the in-depth case examples are extensively discussed in the original text.[2]
Duty to warn versus privacy
A patient with known family history of breast cancer is interested in testing for BRCA1 and BRCA2 pathogenic variant. In reviewing her family history, the health care provider realizes that the patient is not aware of an additional rare but hereditary cancer pathogenic variant in a second-degree relative, which the health center tested and confirmed in the past. After talking with her family, the patient is unable to confirm the details of the second hereditary cancer pathogenic variant and again expresses interest in BRCA1/BRCA2 testing. Does the health care provider have a “duty to warn” the patient of the unknown cancer susceptibility gene in the family, at the risk of disclosing private patient information? The following issues are important to consider in resolving this case.
  1. Preserving the confidentiality of the relative and informing the patient of her cancer risk are both important goals. In general, the health care professional has a “Duty to warn” when there is a high likelihood of harm if not warned, the person at risk is identifiable, the harm of nondisclosure is greater than disclosure, and only the information necessary to prevent harm is released. (Refer to the Privacy and Confidentiality: Disclosure of Patient’s Genetic Information section of this summary for more information.)
  2. It is possible that the benefit outweighs the harm of informing the patient of the second cancer syndrome because the monitoring and management of the rare cancer are different from guidelines for the general population. Additionally both parties are identifiable. An option is to contact the relative for permission to disclose the genetic test result to the patient in question.
  3. If it is not possible to obtain permission to disclose, it is possible to inform the patient that she meets clinical criteria for the hereditary cancer syndrome without releasing specific information about the genetic test results of the relative.
Patient’s right to know versus family member’s autonomy
A patient with a family history of a hereditary cancer is interested in predictive genetic testing and convinces an affected family member, who initially expresses unwillingness, to be tested in order to establish the familial pathogenic variant. In this scenario, the surviving family member admits to feeling pressured into consenting for genetic testing. Both the patient and the affected family member are patients. What takes precedence—the patient’s right to know or the family member’s autonomy? The following issues are important to consider in resolving this case.
  1. Explore, with the patient, alternatives to testing that do not involve the participation of the unwilling family member, such as testing stored tissue of a deceased relative. (Refer to the Value of Testing an Affected Family Member First section of this summary for more information).
  2. If the patient does not want to consider other options and the family member has agreed to be tested without coercion or interference, inform the family member of the implications of the test results, including risks and benefits, and assess her emotional well-being prior to testing.[20] (Refer to the Informed Consent section of this summary for more information.)
Right to know versus right not to know
A hereditary cancer syndrome has been identified in a family. Within that family, an adult child wants a cancer susceptibility test that her parent declined, and one identical twin wants testing but the other does not. Even though the uninterested parties have declined testing and do not want to know the results, it is possible that testing one relative can disclose results for the other family members. Do the rights of the family members interested in predictive testing take precedence over the rights of the relatives who do not want to know? The following issues are important to consider in resolving this case.
  1. In hereditary cancer syndromes, an individual’s right to know takes precedence over an individual’s right not to know especially if there are early detection and prevention strategies to reduce the likelihood of morbidity and mortality.
  2. Since the family has a documented pathogenic variant, standard of care recommendations include guidelines for screening and monitoring. In the event that testing is not done, it is important to take “reasonable steps” to guarantee immediate family members are warned of the hereditary cancer risk. (Refer to the Privacy and Confidentiality: Disclosure of Patient’s Genetic Information section of this summary for more information.)
  3. Pretest and posttest discussions can include the possibility of medical, psychological, and social impact on family members and strategies on how to lessen any negative impact. The patient should honor the wishes of relatives who request not to know and attempt to keep the results secret.[20]
Beneficence versus paternalism
A psychological assessment of a patient interested in predictive testing for an autosomal dominant cancer reveals a history of depression and suicidal attempts. The health care provider is considering denying or deferring testing because of concerns for the patient’s emotional well-being even though the patient refuses a referral to a psychologist because he reports feeling emotionally stable. Is deferring or denying predictive genetic testing a beneficent gesture or an act of paternalism? The following issues are important to consider in resolving this case.
  1. Despite the patient’s refusal to speak with a psychologist, the health care provider can discuss the details of the case with a mental health professional to determine suicidal risk. (Refer to the Psychological Impact of Genetic Information/Test Results on the Individual section of this summary for more information.)
  2. If there is risk of psychosocial disturbances because of test results, it is possible to defer testing. Conditions under which testing can resume are explained to the patient. For example, the NSGC Code of Ethics recommends that clients be referred to other qualified professionals when the patient requires additional services.[20]
  3. Denying a test does not seem justifiable under any circumstances because it implies that the client will never be able to undergo testing.
