in closing the gaps.

s Background: Health care providers are expected to have the skills and knowledge relevant to their field and should also be familiar with the ethical and legal expectations that arise out of the standard practices. Objectives: To elucidate the practice of the health care providers in relation to healthcare ethics in Nigeria. Methods: A self-administered structured questionnaire was devised and distributed to staff of two tertiary health care facilities in Northern Nigeria. The questionnaire comprised of detailed questions regarding day-to-day aspects of Medical ethical issues. Results: A total of 307(76.2% ) out of 403 health care providers responded to the questionnaire. The median age of the respondents was 34 years. More than half 168(54.7%) of the respondents disagreed as to whether “Ethical conduct is important only to avoid legal action. Many respondents 135 (44.0%) agreed to adhering to “patient’s wishes”, on the other hand over two-third of the respondents 211 (68.7%) agreed that “doctor should do what is best” irrespective of the patient’s opinion.

Conclusion: This study has shown gap in knowledge and practice of healthcare ethics among health care providers. There is a need for periodic education on clinical ethics in our hospitals.


Introduction
Ethics is the application of values and moral rules to human activities.Health care providers are expected to not only have the skills and knowledge relevant to their field but also with the ethical and legal expectations that arise out of the standard practices. 1Medical ethics has been founded on the framework of four moral principles of autonomy, beneficence, nonmaleficence, and justice. 2 The first of these principles, autonomy, is the respect for the patient's right to self-governance, choice in care, and the right to accept or refuse treatment.Be-neficence is the obligation to prevent or remove harm while also promoting good by contributing to the welfare and acting in the best interest of the patient.Nonmaleficence implies the obligation of physicians not to inflict harm or adverse effects on the patient from inappropriate or absent care (This principle involves consideration of risks versus benefits from particular procedures).The last ethical principle, justice means distributing benefits, risks, and costs fairly, equitably, and appropriately, and treating patients with similar cases in a similar manner .3,4There has been growing public concern regarding the ethical conduct of healthcare professionals.This often manifests as complaints about poor ethical conduct and an increasing use of litigation against healthcare practitioners. 5The recent increase in number of court cases against hospital workers in Nigeria may reflect gaps in their level of awareness and basic knowledge of medical ethics.All health care workers have a moral obligation to help their patients and the society.It is generally held that physicians should always act in the best inter-est of their patients; but sometimes there is a conflict between obligations to a patient and those perceived to be owed to the community or to other patients.For instance should a doctor discloses the HIV status of a non consenting spouse to the partner or notify the police of a wounded armed robber in doctor's care.
Traditional training offers little help in resolving the ethical dilemmas encountered by physicians.Even among other healthcare professionals there has been no effort to teach ethics and law as separate courses incorporated into the curriculum. 5In order to formulate ethical curriculum relevant to every region, it is pertinent to determine the current basic knowledge and attitudes of the healthcare practitioners in the region.There have been few studies designed to measure what is known and practiced in Nigeria, so that educational efforts may be better targeted.This background forms the basis of the present study with an attempt to elucidate the knowledge, attitude and practice of the health care providers in relation to health care ethics in Nigeria.We hypothesized that health care ethics are deficient in the health care setting.

Methods
This was a descriptive, cross-sectional study among healthcare providers in two government tertiary hospital in Northern Nigeria.Approval was sought from the Hospital ethics review committees of these institutions prior to the study.Participation was completely voluntary.All information collected for this study was anonymous and responses were treated as confidential.
The study was conducted using structured questionnaires, adopted from previous study by Hariharan et al., 6 The questionnaire was designed to examine the staff decision-making process in relation to ethical and legal problems and to identify the healthcare practitioner's values, beliefs and attitudes.The questionnaire was self administered and divided into two sections.The section A of the questionnaire consisted of demographics such as tribe, education level, occupation, age, gender and duration of the working experience and how often an ethical or legal problem is encountered in their practice.On the other side the section B of the questionnaire consisted of respondent's view about questions regarding day-to-day practice of ethics (Appendix 1).
The respondents were divided into two groups for purpose of analysis.One group consisting of physicians and the other of all other service providers in the same setting who would come in contact with patients --these include nurses, pharmacists, physiotherapists, administrators, medical record officers, laboratory scientists and technicians, social workers, clerks and technicians.The responses were based on a 5 point Likert scale: 1strongly disagree, 2-disagree, 3-not sure, 4-agree and 5-srongly agree.

Data analysis
Descriptive analysis was carried out using SPSS version 15.0 (SPSS, Inc, Chicago, IL).The responses of the five point Likert scale were grouped into three: Strongly agree and agree as agree; disagree and strongly disagree as disagree; and the other group was those unsure.Data was quoted as median (interquartile range).The two groups were compared using Pearson's Chi-square test or Fisher's Exact test (as appropriate).P<0.05 was considered as statistically significant.

Results
A total of 307 out of 403 health care providers from various departments responded to the questionnaire (76.2% response rate).There were 216 (70.4%) men and 91(29.6%)women.There were 37 physicians and 270 non-physician health care providers.The demographic characteristics of the respondents are given in Table 1.On whether the children (except in emergency) should never be treated without the consent of their parents or guardian, 228(74.3%)agreed.Two hundred and thirty four (76.2%) disagreed to doctor not refusing to abortion if law permit it, another 267(87%) disagreed to the suggestion of euthanasia and 125(40.7%)agreed they will refer the patient to another doctor, if a patient refused a particular treatment for religious reasons while 31(10%) of respondents were uncertain on how to deal with patients who refuse treatment.Comparison of the responses of physicians and non-physicians on various aspects of the practice of clinical or healthcare ethics is shown in Table 3.There were significant differences (p<0.05) between the perception of physicians and non-physicians on whether they will always inform close relatives about the patient's condition, whether they did what is best for the patient irrespective of the patient's opinion, and whether they will refer patient to another doctor, if a patient refused a particular treatment on religious ground.The response of the physicians and non-physicians also significantly differ on whether patients only need to consent for operations but not for tests or medications, and whether they will agreed with patients who requested their help in dying, and maintaining confidentiality.There were no significant differences in the opinions of physicians and non-physicians regarding other issues such as whether ethical conduct is only important to avoid legal action; whether they considered patients' wishes before taking major decisions on their care; and whether they refused to treat violent patients.
Respondents views were similar on whether they will inform patient when something is wrong, whether they would not treat children without the parent's consent, and whether they will not refuse to perform abortion if the law permitted it.Physicians also share similar opinion with non-physicians on whether hospital staff are free to disseminate/publish hospital information without hospital approval and if they can use patient picture in public forum without the patient's consent (Table 3).
Physicians' reported practices in various situations related to ethical practice were highlighted in Table 3.The majority (70.3%, 26/37) of the physicians disagreed that ethical conduct is important only to avoid legal actions.All the physicians disagreed that confidentially should be abandoned in modern care.Only few (24.3%, 9/37) will always inform close relatives about the patient's condition, majority (59.5%, 22/37) would not treat children without the parent's consent.Seventy-eight percent (29/37) of physicians disagreed that health care worker cannot refuse to perform abortion if the law permitted it.Only (32.4%, 12/37) stated that if a patient refused a particular treatment for religious reasons, they would refer them to another doctor.Most of the physicians (81.1%, 30/37) would not assist a patient who wishes to die to do so, and only one (2.7%) of the physicians will use patient picture in public forum without the patient consent

Discussion
This study showed gaps in knowledge of ethics among healthcare workers in our clinical setting.The fact that over 42% of the respondents agreed that ethics is important only for legal purpose indicates that there is very little knowledge regarding health care ethics in these settings.This is in contrast to similar study among Caribbean health workers where majority of the respondents (94%) disagree with this view. 6This may probably reflect the low level of awareness of health care consumers in sub-Sahara Africa of their rights and of health care providers' obligation to respect those rights.Many of the respondents expressed contradictory views in different areas of ethical issues for instance, many respondents 135 (44.0%) agreed to adhering to "patient's wishes", on the other hand over two-third of the respondents 211 (68.7%) agreed that "doctor should do what is best" irrespective of the patient's opinion.
The findings in this study like similar study in India reflect the paternalistic approach to patient care where physicians are seen like God who knows all. 7However, modern medicine seeks to avoid a paternalistic (doctor knows best) approach to patients.Instead it considers the doctor and patient mutually engaging in the decision making with the final decision on treatment options being that of the patient.In a related study on attitudes towards patient autonomy, Caribbean health care providers showed a greater commitment to patient autonomy than this report .5,6This varied view point among practitioners could have been influenced by the cross-cultural perspectives or exposure to ethical teaching.
The fact that handful of the respondents did not feel that the patient's wishes should be adhered to at all times and majority agreeing that the doctor should always do the best for the patient irrespective of patient opinion, shows the lack of knowledge of the basic principles of medical ethics among the surveyed health care providers.Although, significantly more of the non physicians agreed that doctor should do the best for the patient, close to half of the physicians also hold the paternalistic view.Respect for patient autonomy and informed consent are crucial to ethical practice and is a moral obligation we owe our patients.This moral obligation may only be breached in exceptional circumstances.The paternalistic approach to patient care may be relevant in emergency conditions or when patients would not be able to take rational decision such as unconscious state, mental ill health or a minor.
In health care practice, respecting people's autonomy has many prima facie implications.It requires us to consult people and obtain their agreement before any intervention.
Hence, the obligation to obtain informed consent from patients before offering care to them. 8Notwithstanding our aims of offering each patient net benefit, we must respect their autonomy for what constitutes benefit for one patient may be harm for another.This fact has been illustrated with mastectomy for breast cancer.Mastectomy may constitute a prospective net benefit for one woman with breast cancer, while for another the destruction of an aspect of her feminine identity may be so harmful that it cannot be outweighed even by the prospect of an extended life expectancy. 8 is important to note, that the theory of contemporary medical ethics is a typical American product and it remains a concern whether it will spread globally.There are growing dissenting voices, even in western countries such as the United Kingdom, regarding the application of the principle of autonomy in medical field which are being supported by an argument that it erodes the trust between the patient and the treating physician. 9This may explain why about 44 % of the respondents in the present study did not agree to the view that the patient's wishes should always be adhered to and about a twothird of the respondents agreed to the paternalistic attitude of physicians while treating a patient.This finding is consistent with that of Caribbean study where 45% of the respondents did not agree to the view that the patient's wishes should always be adhered to. 6Medical confidentiality is another implication of respecting people's autonomy.Health care workers explicitly or implicitly promise their patients that they will keep confidential the information confided to them as a matter of code of professional conduct.Keeping promises is also a way of respecting people's autonomy.Without such promises of confidentiality patients are also unlikely to divulge the highly private and sensitive information that is needed for their optimal care. 8intaining patient's confidentiality has always been an ethical dilemma.In the present study, the responses to the question regarding confidentiality varied widely.While majority agreed to the view that patient confidentiality is very important and should not be abandoned, almost 65% of the respondents also opined that patient's relatives should be told of the patient's condition.In a study of 364 health care providers in Queen Elizabeth hospital, Barbados, one-third of the respondents also felt that patient's relatives should be told of the patient's condition. 6What is common in these studies is the diverse cultural influence which has been described as the major issues in present day bioethics. 8,10,11alth care workers in Africa similar to Asia communities are more likely to be confronted with moral conflicts because of the less demands for self actualization of their people compare to their counterparts in the West. 10Traditionally, family and community carry a greater weight in African/Asian value systems than individuals.It will always be difficult not to inform relative of patient's condition, whom in the first instance are likely to bring patient to hospital and also most of the time be responsible for the cost of treatment.
One phenomenon highlighted in previous reports is the difference between East Asian countries and North America/Europe as regard the locus of authority in decision-making: North America/Europe demands and promotes the value of individual autonomy; East Asian countries typically honor and uphold the value of family autonomy .12,13The philosophy in sub-Saharan African countries is similar to Asian countries.In a well written appraisal of the four principles of medical ethics plus attention to scope by Gillion, 8 he emphasized the tendency to disagree about scope of application of the principle of ethics especially about to what or to whom we owe these moral obligations. 8terestingly, even if we agree that the scope of the principle of respect for autonomy is universal, encompassing all autonomous agents.The question remains as to who or what counts as an autonomous agent?. 8 The author however answered the philosophical questions: health care workers should acknowledge that the autonomy of everybody even young children and severely mentally impaired people should prima facie be respected unless there are good moral reasons not to do so and that those reasons should highly be on the context. 8rom the foregoing, it is clear that the health care eth-ics strives to maximize the good by producing the best balance of benefit and harm.It forces us to look at all potential consequences of our decisions.On issue of confidentiality, the ideal ethical practice for health care providers is to consider how best to act in the interest of their patient whilst still respecting the involvement of the family in the decision.
In the present study, significant number of the respondents disagreed that health care workers cannot refuse abortion if law permits it.This finding may reflect the influence of religious values in the respondents.In a similar vein, there was 87% disagreement for the practice of euthanasia.This finding is consistent with previous studies where overwhelming majority of the respondents voted against abortion and euthanasia. 6,14 is important to understand that vast majority of Nigerians are staunchly religious people and they value the teachings of their religion more than the secular thoughts.More importantly, this study was conducted in region which is densely populated with Muslims.The main Islamic guiding principles are respect for human dignity and the maintenance and protection of life, property and honor.Because of the unconditional valuation of human life, every additional day lived is of value; a treatment that prolongs life therefore cannot be harmful.The trust in an omnipotent God is a second reason why decisions to forgo life-prolonging treatments cannot be justified. 15'Muslims feel very strong that it is Allah who does the actual healing, the doctor being only the agent for the will of Allah, 16 just like in Christianity.It has previously been hypothesized that strong religious background may have a profound influence in the practice of ethics in a hospital setting, since religion makes a big difference in clinical healthcare delivery to both provider and the patient, although not invariably. 6,17ligion and its concomitant sanctity of life position provide support to physicians who hold the belief that death should not be deliberately hastened. 18,19Control over life and death (and its timing) is with nature or the divine. 20Accordingly, such a position precludes any acceptance of a request to die or any intentional autonomous action of the physician to hasten death.This views cut across broader political, legal and professional positions, and even across specialties. 21Contrary views to such commonly accepted positions on hastening death are, however, also provided by some physicians who consider patient choice and autonomy most important in directing their position on controlling the timing of death.Many physicians state that they would not intentionally hasten death regardless of whether it is requested or not, but death sometimes occurs as a consequence of addressing patient suffering. 21e findings of this study has demonstrated knowledge gap in health care ethics among both physicians and non-physicians.The fact that varying range of respondents had "no answer" to most of the questions may indicate their lack of awareness or knowledge in that area, their inability to decide or commit a specific response, or their disinterest.
Comparing the two groups of health care providers, responses from both physician and non-physicians to questions pertaining to practical ethics were most common ethical issues (Table 3).There were significantly stronger opinions of the physician on issues like with respect to confidentiality, informing relative about patient condition, doctor doing the best for the patient irrespective of patient opinion; consent for procedures and referring noncompliant patients.There was also a significant difference of opinion between physician and non physician on whether patient who wishes to die should be assisted in doing so.The varying opinions of the respondents in the present study may reflect the difference in the intensity of training between these professionals and also the degree of interaction with patient.

Limitations
Participants' practices were self-reported and their responses may have reflected what they believed were appropriate.The study involved two tertiary hospitals in Northern Nigeria, the results may not necessarily be representative to all hospital healthcare providers.

Conclusion
This study has shown gap in knowledge and practice of healthcare ethics among both physicians and non-physicians in our setting.For the field of healthcare ethics to continuously advance, healthcare workers need to devote more attention to ethical reflection.The study also suggests that most literature and teaching on healthcare ethics emphasize on the so called "western" perspective of ethics which are formulated and applicable to the healthcare profession in the western countries.However, it is necessary to formulate medical ethics within the context of the individual socio-economic, geo-political, religious and cultural background.The need for periodic continuing education on clinical ethics utilizing a multidisciplinary approach to bridge the gap in ethical knowledge and practices between different healthcare personnel cannot be overemphasized.This study should serve as a stimulus to help promote the growth in all areas of ethical discourse.
