The Relationship Between Students' Attitude Toward Euthanasia and Optimism: A Descriptive Study

During the recent decades, the main cause of mortality has changed from acute infectious diseases to cardiovascular disease, accidents, and malignancies. Although new treatments have increased the lifespan of such patients, the importance of these diseases is associated with many disabilities for patients and a clear decrease in their quality of life. On the other hand, the presence of new care technologies in intensive care units has made the disabled patients, even those who are brain dead, survive in intensive care units. Most of these patients suffer from a lot of pain without any hope of recovery (1). On the other hand, a lot of expenses may be imposed on the family or health system. Thus, the issue of murder is related to pity or euthanasia with new dimensions. Particularly, it is worth considering the needs of patients in such cases by reinforcing the principle of autonomy or self-righteousness in modern medical ethics. The way of treating the patients in the days and hours of their lives has always been a problem for health care providers including physicians and nurses (2). Making a decision to continue the therapeutic interventions of the end-of-life care patients are the essential skills required by the health care system creating many scientific, ethical, religious, and legal challenges, and sometimes making it difficult to make decisions. Euthanasia is considered as one of the issues raised for the end-of-life care patients. The term “euthanasia” was derived from two words (eu) meaning good and (thanatus) meaning death. Euthanasia refers to killing someone suffering from an incurable disease without causing any pain. In addition, it is the synonym for murder due to pity (3). From the public’s point of view, physicians are the best choice for euthanasia due to the fact that they have access to the necessary tools and knowledge as well as the medicines, which are effective in the rapid and painless killing of humans (4).

In the content of all divine religions, killing a human being is forbidden and since euthanasia is a kind of murder, and appropriate care and attention to the end-of-life care patients are regarded by all religions, Islam does not allow voluntary death to individuals (3). However, there is an increasing pressure to resolve this issue whether physicians and other therapists can contribute to the death of patients in specific circumstances due to the request of patients or families or should generally avoid this issue (5). Several studies were conducted on euthanasia around the world. The quantitative and descriptive study conducted in South Africa on 277 third-year and fourth-year medical students aimed at examining the euthanasia attitude of future physicians as well as indicated that 52.7% of students believed that euthanasia should be legalized. Furthermore, most students (80.1%) believed that the Medical Ethics Committee should be in charge of decision-making in regards to euthanasia while 49.1% of students stated that they would end the life of patients suffering from pain, 36.1% believed that they would not take any action, and 35% stated that they would provide conditions for the patient to end his life (6). Another review study evaluated the health care providers’ euthanasia attitude. The main questions raised in this study were “what is the role of health care providers in euthanasia attitude?” and “what challenges do health care providers face on the patient’s request on euthanasia attitude?”. Among 1715 articles, 33 articles on nurses, patients, social workers, physicians, and examiners were subject to thematic analysis. The results indicated that euthanasia requires the development of a protocol and law in terms of the roles of health care providers. This study indicated that there is no accurate information from the viewpoint of health care providers at the time of request (7). Another study examined and compared the euthanasia attitude of Iranian and American students regarding their individual and cultural characteristics. The results indicated that the American samples had a more positive attitude toward euthanasia while diversity and dispersion were observed among the Iranian samples. Honesty, humility, and openness to experience were the predictive factors in both Iranian and American samples. However, agreeableness is considered as a predictor among the Iranians (8). Another qualitative study explained the challenges faced by Canadian physicians performing euthanasia. A number of 16 physicians in Canada went under semi-structured interviews by telephone. The results indicated that the physicians faced these challenges: (1) improving the relationship with the colleagues performing euthanasia and the tension of the relationship with other colleagues, (2) insufficient financial damages regarding the time they allocated, and (3) large loads of work in such a way that their personal time was sacrificed (9). Regarding the studies conducted in Iran, a descriptive-analytical study was conducted on 165 students to examine their euthanasia attitude and their personality traits. The results indicated that religious beliefs, honesty-humility, agreeableness, and extraversion were associated with a negative attitude toward euthanasia while openness was related to euthanasia acceptance (10). A study of 190 students addressed altruism and other personality traits with euthanasia acceptance. Higher scores in altruism, humility, honesty, agreeableness, and conscientiousness were associated with euthanasia non-acceptance. Altruism explained the most variance of euthanasia attitude beyond gender, religion, and personality factors (11). Further, a descriptive study on 266 nurses from Hajar and Kashani hospitals in Iran indicated that 57.4%, 3.2%, and 39.5% of nurses had negative and positive attitudes toward euthanasia (12). Another descriptive study by Alborzi et al., among the nurses of the intensive care unit for infants and adults in terms of euthanasia attitude in Jondishapur Hospital, Ahwaz indicated that the attitude of all nurses to euthanasia was negative and there was a significant difference between euthanasia attitude and moral distress. However, no significant relationship was found between the severity of moral distress and euthanasia attitude. In this study, it was concluded that the non-acceptance of euthanasia by nurses can be related to the Iranian and Islamic culture (13). Another study examined the euthanasia attitude of the patients referring to the neurology clinic and their relatives. In this study, four groups including dying patients, relatives of dying patients, patients with depressive disorder, and the patients with no depression disorder were selected. In general, 64 participants including 34 females and 30 males were studied. The results indicated no significant relationship between gender and euthanasia attitude, as well as between the four groups and attitude (14).

The two main groups involved in euthanasia are patients and physicians and studying their attitudes towards this phenomenon plays a critical role in the legal or meta-legal prevalence of such performance in hospitals. The lack of a coherent, complete, and efficient law for all aspects of euthanasia is another reason for the necessity of conducting a study regarding the attitudes of physicians and patients in regards to this issue. The studies conducted in this field in western countries cannot be generalized to Iran due to the great cultural differences and their different beliefs (15-17). Furthermore, the studies conducted in other Islamic countries can not indicate the state and needs in Iran. However, few studies have been conducted in this area in Iran.

As mentioned in the latest studies on euthanasia, some studies were conducted in Iran with respect to the attitudes of nurses and patients. However, fewer studies were conducted in the field of euthanasia for physicians, especially their performance.

The present study aimed to investigate the euthanasia attitude and its relation to optimism among the medical and nursing students of AJA University of Medical Science.

The present study was a descriptive study. The population included the clinical students at Imam Reza Hospital, among whom 150 nursing and medical science students were selected based on the census method. The exclusion criteria were the lack of willingness to participate in the study, being a guest at the time of completing the questionnaire (student of AJA University of Medical Science), and lack of completing the questionnaire appropriately.

The present study aimed to investigate the medical students’ attitudes toward the end-of-life care among the end-patients in the academic year 2017 - 2018 in AJA University of Medical Science. In this study, 150 clinical students were studied, among whom 50 nursing students, 50 online students, and 50 stager. The mean age (2.35) was 23.91 and the mean scores of optimism and attitudes to the end-of-life care were 24.4 (4.39) and 23.54 (2.38), respectively.

Among all of the selected students, a direct and significant correlation was observed between optimism and euthanasia attitude (P = 0.007 and r = 0.219) while there was a negative and significant correlation between age and optimism (P = 0.012, r = -0.35), as well as between age and attitude (P < 0.001 and r = -0.55) among the nursing students. However, this correlation was not observed among the medical students. Other data related to the correlation between optimism, attitude, and age are presented in Table 1 in terms of field of study and academic level.

The mean score of euthanasia attitude among nursing and medical students was respectively 23.2 (2.31) and 23.72 (2.4) while Mann-Whitney test showed no significant difference between the two groups (P = 0.22). The mean score of optimism among nursing and medical students was respectively 23.4 (3.81) and 24.6 (4.62), although no significant difference was found between the two groups (P = 0.07).

In addition, independent t-test and Mann-Whitney indicated no significant difference between attitude, field of study, and academic level as well as between optimism, field of study, and academic level (P > 0.05). Significantly, only the optimism mean score was higher in stager in comparison to nurses (P = 0.052); in addition, Table 2 indicates the pairwise comparison of the two considered variables.

The present study investigated the attitude of Army Medical University students towards end-of-life care. The mean score of optimism was about half the optimism score (maximum optimism score = 40). The mean score of euthanasia attitude was more than half of the attitude questionnaire score (maximum score of 30), indicating that students had no appropriate attitude toward euthanasia and considered the end-of-life care desirable. The results of the present study is consistent with the studies of Aghayi among nurses, on the end-of-life care (20), Moqadasian’s study among the nursing students’ attitudes in Tabriz and Kurdistan toward non-resuscitation on non-resuscitation and inactive euthanasia (19). In the above-mentioned studies, nurses had a favorable attitude to end-of-life care. However, the results of this study are not consistent with the study conducted among the students in the USA (8). In the above-mentioned study, medical students had a favorable euthanasia attitude while a considerable difference was observed in euthanasia attitude among the Iranian students. This lack of coordination can vary due to the differences in the culture and beliefs among the students in different educational environments.

In the present study, a correlation was observed between age and euthanasia attitude. The results of this study are in line with the study by Naseh et al., which evaluated the relationship between euthanasia and the underlying characteristics of nurses and specialists (12). However, in the above-mentioned study, an inverse association was found between euthanasia and age among nurses (12), which was incongruent with the result in the present study, in which a direct relationship was found between the age of nursing students and interns and euthanasia attitude. The results of this study are inconsistent with the studies by Hojjati et al. (21) and Aghaei et al. (20), indicating no relationship between euthanasia attitude and attitude. In another study conducted in Jordan, nurses’ attitudes and their characteristics were considered and the results of this study are not in line with those of the present study. Furthermore, the age group of 40 years had a more favorable attitude than the age group of 20 - 29 years (22).

In the present study, the students’ euthanasia attitudes and their optimism were directly related while optimism was associated with their inappropriate euthanasia attitude. Although no study was found to investigate this personality trait, some studies evaluated the attitude and other personality traits. In the study conducted by Aghababayi et al., the personality traits of religiously, honesty-humility, agreeableness, and extraversion were associated with a negative attitude toward euthanasia (10). Another study indicated that altruism explained the most variance of euthanasia attitude beyond gender, religiously, and a personality factor (11), which is consistent with the findings of the present study in terms of the relationship between euthanasia attitude and the personality trait considered in the present study.
