Family Physicians’ Management of Genetic Aspects of a Cardiac Disease: A Scenario-Based Study from Slovenia

Family Physicians’ Management of Genetic Aspects of a Cardiac Disease: A Scenario-Based Study... The aim of this study was to find out how Slovenian family physicians (FPs) would manage a hypothetical clinical case, to explore their views about possible ethical dilemmas associated with this clinical case and to determine possible associations with demographic and other characteristics of FPs. This was an observational cross-sectional postal study in the Slovenian FPs' surgeries. The study population consisted of the whole population of Slovenian FPs (n = 950). The main outcome measures were the percentages of the answers of FPs on different questions about the clinical case on the management of patient and his relative with hereditary cardiomyopathy. There were 271 FPs who answered the questionnaire (response rate was 27.1%). A sample included 66 (24.4%) men and the mean age of all respondents was 45.5 ± 10.6 years. When dealing with the clinical case, most FPs expressed willingness to take the patient's family history. Only 34.2% FPs did not believe that ordering genetic tests was part of their job. Additionally, only 50.0% of them felt competent to interpret the genetic risk, 25.0% of them would give information about genetic testing and only 6.0% would interpret the results of the genetic testing.

Keywords: Case management; Family medicine; Genetics. INTRODUCTION Preventive activities are an important part of patient management at primary health level. Taking into account the effect of family and society when dealing with individual patients is also one of the core competencies of family medicine [1]. In the era of rapid evolvement of genetic medicine, family physicians (FPs) increasingly face the activities and dilemmas associated with the management of genetic aspects of disease and prevention [2]. Genetics is rarely taught at the undergraduate and postgraduate level of medical education of non genetic specialities [3]. It has already been shown that FPs had low confidence in their ability to carry out basic medical genetic tasks [4] but were aware of their need for additional education and even expressed their educational needs [5]. Even though family history is a crucial part of patient management in family medicine, its association with possible genetic background of disease develop- ment and higher disease risk is not yet fully used in practice [6,7]. Traditionally, family history taking is focused on the patients with symptoms or problems, which might imply that the patient is having a higher risk for the development of some chronic diseases, such as diabetes, coronary disease or asthma [8]. Healthy patients or patients' relatives are rarely being asked about their family history [9] Also, FPs very rarely decide to refer patients at risk to clinical genetics [10]. Family physicians regularly face ethical dilemmas in their everyday practice [11] and find the management of some of them quite difficult [12]. Genetic medicine is undoubtedly associated with many ethical dilemmas [13]. Similarly, many dilemmas can also be encountered when performing preventive activities such as screening for some diseases [14]. Therefore, the field of genetics in preventive activities performed in patients and their healthy relatives is a very sensitive area. Combined with the lack of knowledge of genetics [15], the FPs may face serious difficulties and doubts, and may feel reluctant to perform such activities even though genetic concepts are clearly part of current FPs practice in form of clinical decision making based on family history [16,17]. This was also shown in a clinical case scenario-based study with more than 60.0% of FPs who were willing to take family history but only 16.0% willing to order a genetic test [18]. Similarly, primary care providers seem to assess breast cancer risk mainly by family history but rarely discuss genetic testing with the patients [10]. In Slovenia, as in many other European countries [3], genetic medicine is taught at the undergraduate level. However, it is not taught as a part of family medicine specialization curriculum [19]. The aim of this study was to find out how Slovenian FPs would manage a hypothetical clinical case and to explore their views about possible ethical dilemmas associated with this clinical case. MATERIALS AND METHODS Study Design. This observational cross-sectional postal study was conducted in Slovenia. It was approved by the Slovenian Ethics Committee (No. 40/09/12). Participants. All Slovenian FPs were invited to participate in the study. According to the internal data of the Slovenian Medical Chamber (membership is obligatory for all Slovenian physicians), there were 950 working FPs in Slovenia at the time of the study. Data Collection. We collected data by a postal survey sent in March 2013. The mail consisted of the questionnaire (described below), the invitation letter, and a pre stamped return envelope. Table 1.

First, the questionnaire was translated into the Slovenian language by two independent experts who agreed on its Slovenian version. Two independent experts then translated it back into the English language. Finally, both experts agreed on the final version of the Slovenian questionnaire. The questionnaire consisted of the demographic questions (see Table 1) and questions about previous attendance to genetic education (see Table 1), of the scenario of clinical case and the questions on how to manage it, of the questions about the use of genetic knowledge in everyday management of patients, of the questions on the educational needs of FPs and of the questions on the self-perceived importance of providing genetic tests' information (see Tables 2 and 3). In Table 2, items 1-9 could be answered with the following options: family physician, cardiologists, genetic specialist. We dichotomized the answers into two categories: family phy- sician/other for the purpose of statistical analysis. In Table 3, items 10-18 could be answered with most likely, likely, unlikely and no. Again, we dichotomized the answers into two categories: yes/no, including most likely and likely to "yes" and unlikely and no to "no". Only the data on the management of patients described in the scenario and its associations with demographic and other characteristics of FPs are reported in this article. The Scenario of a Clinical Case. Mr. Smith (aged 35) came to your surgery because his 27-yearold brother, a competitive swimmer, has just died suddenly. He collapsed in the pool and despite defibrillation was found to be dead. Although sudden death might not immediately suggest a genetic condition, Mr Smith is worried because his mother's sister died suddenly aged 30 and he asks whether the same may happen to him, his children Melanie (12 years), and Tom (6 months) or his brother (32 years). He has been told that his brother's postmortem demonstrated hypertrophic obstructive cardiomyopathy, which can be inherited as an autosomal dominant condition.

Genetic testing may lead to identification of patients at high risk for sudden death as early as 10 years of age. Treatment can be considered with implantable defibrillators or medication. Mr Smith has agreed to be tested and the inherited mutation has been found but he does not want to inform his brother. Data Analysis. We analyzed the data by the Statistical Package for the Social Sciences (SPSS) version 13.0 (SPSS for Windows; SPSS Inc., Chicago, IL, USA). We performed the descriptive analysis. In the bivariate analysis, we used the independent t-test and c2 test. We set the limit for statistical significance at a p value of <0.05. RESULTS There were 271 (27.1%) FPs who completed the questionnaire, out of which 66 (24.4%) were men and 205 (75.6%) were women (Table 1). Mean age of the sample was 45.5 ± 10.6 years. Mean age of the men was 50.1 ± 11.8 and mean age of the women was 43.9 ± 9.7 (p <0.001). Mean working period of the sample was 17.3 ± 11.6 years and mean time from graduation 19.6 ± 10.9 years. Mean number of patient seen by the FP in the previous week was 213.7 ± 77.7. When dealing with the clinical case, most FPs expressed willingness to take Mr. Smith's family history. More than 70.0% of FPs would tell Mr. Smith that it was his responsibility to tell his brother about the genetic risk and almost 90.0% would tell Mr. Smith to tell his brother to come to see them. In the last case, more than 90.0% of FPs would inform Mr. Smith's brother about the risk by themselves (Table 2). Younger FPs were more inclined to give the information to Mr. Smith (t = ­2.040, p = 0.042). Similar associations were found regarding years from graduation (t = ­2.054, p = 0.041). Younger FPs (and those with less working years) would also more likely respect the wish of Mr. Smith not to inform his brother about the mutation (t = ­2.112, p = 0.036; t = ­2.065, p = 0.040; respectively). On the other hand, older FPs, FPs with more working years and with more time since graduation would inform Mr. Smith's brother on his next visit to the practice (t = 3.112, p = 0.002; t = 2.823, p = 0.005; t = 2.925, p = 0.004). Similar findings were detected also in terms of association of age/years from graduation/ working experiences and respecting or disrespecting the patient's wish regarding his brother and referrals to clinical specialists (Table 3). DISCUSSION More than 70.0% of Slovenian FPs believe that taking family history is a part of their everyday job. On the other hand, up to 70.0% of them do not be- lieve that ordering and discussing genetic tests or their implications is part of their job. Additionally, only 50.0% of them feel competent to interpret the genetic risk, 25.0% of them would give information about genetic testing and only 6.0% would interpret the results of the genetic testing. This is the first study on FPs' attitudes to genetic management of patients in Slovenia and also in the southeastern part of Europe. A study using the same questionnaire and also the same clinical case scenario was conducted in France, Germany, The Netherlands, Sweden and the UK, and showed that 61.0% of FPs would take a family history but only 38.0% would explain an inheritance pattern and 16.0% would order a genetic test [18]. In our study, the percentages of FPs taking a family history are higher than in the previously mentioned European studies. Also, Slovenian FPs seem to be more willing to engage in other genetic activities (i.e., explaining the inheritance pattern, ordering a genetic test) than their colleagues from some European countries, even though the percentage of them willing to do so is still low. A similar study on the FPs' views on their role in cancer genetic services showed that 60.0% of them would take a detailed family history from the patient, almost 80.0% would decide which patients should be referred to genetics clinic and a quarter of them would counsel the patient on cancer risk [21]. It seems that FPs were willing to engage in genetic activities but clearly distinguish between the routine use and function of family history in clinical decision making and contrasting conceptualizations of genetics and genetic conditions as shown by Mathers et al. [16]. Family physicians seem to be willing to embrace genetics as a part of their work from the aspect of core competencies of family medicine (comprehensive approach) and not from an isolated clinical genetics view. Nevertheless, they expressed a very strong opinion about family history taking as their task and we have to take into account that family history is a basic genetic tool [22,23]. Each time a genetic test is undertaken by physicians or by patients themselves, its results will inevitably affect not only the life of the patients but also of their relatives. Confidentiality is one of the basic principles that have to be followed by any physician [24]. However, in some cases (i.e., a duty to warn relatives about risk of some infectious diseases or to warn public about an imminent harm) physicians are legally allowed to breach confidentiality. As far as the notification of family members of the identification of a genetic mutation by physicians is concerned, no clear answer yet exists [25]. It is an example of a conflict between the physician's ethical obligations to respect the privacy of genetic information and the potential liabilities resulting from the physician's failure to notify at risk relatives [26]. According to our study, FPs believe that it is the patients' responsibility to notify their relatives at risk and they would even encourage patients to do so. A majority of them would even offer to help them to inform their relatives. Similarly, UK physicians considered informing family members about genetic risk as a family responsibility [27]. Over two-thirds of medical geneticists in a the USA study [28], believed they should bear the responsibility of warning their patients' relatives when found to be at risk for genetic disease. However, only one quarter of those who faced the dilemma of a patient refusing to notify their at risk relatives seriously considered disclosure to those at risk relatives without the patient's consent [28]. In our study, almost 70.0% of FPs would not respect the patients' wishes not to inform their relatives and would inform them by themselves when first seeing them in the practice. Clearly, FPs are not clear about the correct procedure of informing relatives about genetic risk but according to other studies, this is a wider problem which has not yet been solved [29]. The results of our study highlighted some differences regarding demographic and professional characteristics. The most obvious one was age. It seems that younger FPs were more willing to include genetic tasks into their everyday practice. Also, they appeared to be more sensitive to ethical issues. A study based on the same clinical case [18] showed some differences regarding gender: male FPs seemed to be more willing to perform genetic tests. In our study, male FPs were only found to be more inclined to inform Mr. Smith's brother about the genetic risk. Taking into account that similar associations as with age were found also regarding working years and years since graduation, the differences might be the consequence of the previous finding that the younger generation was more confident in their abilities about genetic tasks and have more genetic knowledge [4,15]. The older generation, on the other hand, usually did not want to change their steady management of patients. We also observed differences regarding education as the physicians with more genetic education and those with the family medicine specialization would be more willing to refer patients to genetic and/or cardiovascular assessment. Greater sensibility of younger and more educated FPs could be the consequence of a new program of family medicine specialization, which also introduced ethical topics to the curriculum [19]. This was also shown by previous studies in Slovenia [12,30]. These findings indicate the need for the introduction of genetic topics to family medicine specialization curriculum. This study was performed in a representative sample of Slovenian FPs and its findings can therefore be generalized to the whole population of FPs in Slovenia. The strength of this study is also the use of a previously validated questionnaire which gives us confidence in the reliability of data. This was a cross-sectional study so it is not possible to detect any causal relationship between variables. The response rate in this study was expected, as a 20.0% response rate is usual for postal surveys [12,31]. Nevertheless, it can be a source of selection bias. Also, the use of a theoretical clinical case represents simulated environment, thus in reality, physicians might have decided differently. attitudes towards ethical issues associated with genetic medicine.

Genetic testing may lead to identification of patients at high risk for sudden death as early as 10 years of age. Treatment can be considered with implantable defibrillators or medication. Mr Smith has agreed to be tested and the inherited mutation has been found but he does not want to inform his brother. Data Analysis. We analyzed the data by the Statistical Package for the Social Sciences (SPSS) version 13.0 (SPSS for Windows; SPSS Inc., Chicago, IL, USA). We performed the descriptive analysis. In the bivariate analysis, we used the independent t-test and c2 test. We set the limit for statistical significance at a p value of <0.05. RESULTS There were 271 (27.1%) FPs who completed the questionnaire, out of which 66 (24.4%) were men and 205 (75.6%) were women (Table 1). Mean age of the sample was 45.5 ± 10.6 years. Mean age of the men was 50.1 ± 11.8 and mean age of the women was 43.9 ± 9.7 (p <0.001). Mean working period of the sample was 17.3 ± 11.6 years and mean time from graduation 19.6 ± 10.9 years. Mean number of patient seen by the FP in the previous week was 213.7 ± 77.7. When dealing with the clinical case, most FPs expressed willingness to take Mr. Smith's family history. More than 70.0% of FPs would tell Mr. Smith that it was his responsibility to tell his brother about the genetic risk and almost 90.0% would tell Mr. Smith to tell his brother to come to see them. In the last case, more than 90.0% of FPs would inform Mr. Smith's brother about the risk by themselves (Table 2). Younger FPs were more inclined to give the information to Mr. Smith (t = ­2.040, p = 0.042). Similar associations were found regarding years from graduation (t = ­2.054, p = 0.041). Younger FPs (and those with less working years) would also more likely respect the wish of Mr. Smith not to inform his brother about the mutation (t = ­2.112, p = 0.036; t = ­2.065, p = 0.040; respectively). On the other hand, older FPs, FPs with more working years and with more time since graduation would inform Mr. Smith's brother on his next visit to the practice (t = 3.112, p = 0.002; t = 2.823, p = 0.005; t = 2.925, p = 0.004). Similar findings were detected also in terms of association of age/years from graduation/ working experiences and respecting or disrespecting the patient's wish regarding his brother and referrals to clinical specialists (Table 3). DISCUSSION More than 70.0% of Slovenian FPs believe that taking family history is a part of their everyday job. On the other hand, up to 70.0% of them do not be- lieve that ordering and discussing genetic tests or their implications is part of their job. Additionally, only 50.0% of them feel competent to interpret the genetic risk, 25.0% of them would give information about genetic testing and only 6.0% would interpret the results of the genetic testing. This is the first study on FPs' attitudes to genetic management of patients in Slovenia and also in the southeastern part of Europe. A study using the same questionnaire and also the same clinical case scenario was conducted in France, Germany, The Netherlands, Sweden and the UK, and showed that 61.0% of FPs would take a family history but only 38.0% would explain an inheritance pattern and 16.0% would order a genetic test [18]. In our study, the percentages of FPs taking a family history are higher than in the previously mentioned European studies. Also, Slovenian FPs seem to be more willing to engage in other genetic activities (i.e., explaining the inheritance pattern, ordering a genetic test) than their colleagues from some European countries, even though the percentage of them willing to do so is still low. A similar study on the FPs' views on their role in cancer genetic services showed that 60.0% of them would take a detailed family history from the patient, almost 80.0% would decide which patients should be referred to genetics clinic and a quarter of them would counsel the patient on cancer risk [21]. It seems that FPs were willing to engage in genetic activities but clearly distinguish between the routine use and function of family history in clinical decision making and contrasting conceptualizations of genetics and genetic conditions as shown by Mathers et al. [16]. Family physicians seem to be willing to embrace genetics as a part of their work from the aspect of core competencies of family medicine (comprehensive approach) and not from an isolated clinical genetics view. Nevertheless, they expressed a very strong opinion about family history taking as their task and we have to take into account that family history is a basic genetic tool [22,23]. Each time a genetic test is undertaken by physicians or by patients themselves, its results will inevitably affect not only the life of the patients but also of their relatives. Confidentiality is one of the basic principles that have to be followed by any physician [24]. However, in some cases (i.e., a duty to warn relatives about risk of some infectious diseases or to warn public about an imminent harm) physicians are legally allowed to breach confidentiality. As far as the notification of family members of the identification of a genetic mutation by physicians is concerned, no clear answer yet exists [25]. It is an example of a conflict between the physician's ethical obligations to respect the privacy of genetic information and the potential liabilities resulting from the physician's failure to notify at risk relatives [26]. According to our study, FPs believe that it is the patients' responsibility to notify their relatives at risk and they would even encourage patients to do so. A majority of them would even offer to help them to inform their relatives. Similarly, UK physicians considered informing family members about genetic risk as a family responsibility [27]. Over two-thirds of medical geneticists in a the USA study [28], believed they should bear the responsibility of warning their patients' relatives when found to be at risk for genetic disease. However, only one quarter of those who faced the dilemma of a patient refusing to notify their at risk relatives seriously considered disclosure to those at risk relatives without the patient's consent [28]. In our study, almost 70.0% of FPs would not respect the patients' wishes not to inform their relatives and would inform them by themselves when first seeing them in the practice. Clearly, FPs are not clear about the correct procedure of informing relatives about genetic risk but according to other studies, this is a wider problem which has not yet been solved [29]. The results of our study highlighted some differences regarding demographic and professional characteristics. The most obvious one was age. It seems that younger FPs were more willing to include genetic tasks into their everyday practice. Also, they appeared to be more sensitive to ethical issues. A study based on the same clinical case [18] showed some differences regarding gender: male FPs seemed to be more willing to perform genetic tests. In our study, male FPs were only found to be more inclined to inform Mr. Smith's brother about the genetic risk. Taking into account that similar associations as with age were found also regarding working years and years since graduation, the differences might be the consequence of the previous finding that the younger generation was more confident in their abilities about genetic tasks and have more genetic knowledge [4,15]. The older generation, on the other hand, usually did not want to change their steady management of patients. We also observed differences regarding education as the physicians with more genetic education and those with the family medicine specialization would be more willing to refer patients to genetic and/or cardiovascular assessment. Greater sensibility of younger and more educated FPs could be the consequence of a new program of family medicine specialization, which also introduced ethical topics to the curriculum [19]. This was also shown by previous studies in Slovenia [12,30]. These findings indicate the need for the introduction of genetic topics to family medicine specialization curriculum. This study was performed in a representative sample of Slovenian FPs and its findings can therefore be generalized to the whole population of FPs in Slovenia. The strength of this study is also the use of a previously validated questionnaire which gives us confidence in the reliability of data. This was a cross-sectional study so it is not possible to detect any causal relationship between variables. The response rate in this study was expected, as a 20.0% response rate is usual for postal surveys [12,31]. Nevertheless, it can be a source of selection bias. Also, the use of a theoretical clinical case represents simulated environment, thus in reality, physicians might have decided differently. attitudes towards ethical issues associated with genetic medicine.
