Abstract
Introduction
Professional codes of ethics guide nurses’ practice. They describe the values and principles of the profession, which aim to support nurses’ ethical decision making and express the profession’s obligations to society. The International Council of Nurses’ Code of Ethics unifies the profession globally, 1 while national codes respond to local nursing needs. Codes of ethics provide a foundation for nurses’ ethical competence.2,3 Throughout nursing’s history codes of ethics have been revised periodically due to changes in practice, technology, emerging concerns, and societal developments. 1 Thus, professional codes of ethics are a living document, designed to guide nurses now and in the future. 4
A profession, like nursing, is characterized by its willingness to comply with ethical and professional standards as they are defined in the profession’s codes of ethics. They also support the development of the professional group identity.5,6 Nurses’ codes of ethics have both external and internal functions. External functions describe the profession’s position in society, whereas internal functions describe a normative set of rules.7,8 As an external function, nurses’ codes of ethics express the values of the profession, the codes’ importance in the recognition of patients’ rights, and how the profession addresses ethical obligations to society.7,9 Thus, the professional codes of ethics serve as the social contract between the public and the nursing profession. 7 As an internal function, codes of ethics describe standards of ethical practice, moral obligations, and acceptable behaviors.10,11 Codes of ethics are a form of professional self-regulation to which professionals as individuals and as a group commit themselves voluntarily. 8
Background
This study focuses on Code of Ethics for Nurses with Interpretive Statements published by the American Nurses Association (hereafter the Code). 2 American Nurses Association (ANA) is a national nursing organization representing the interests of more than five million registered nurses. ANA advances the profession fostering high standards of nursing practice, promoting a safe and ethical work environment, bolstering the health and wellness of nurses, and advocating health care issues that affect nurses and the public (https://www.nursingworld.org). Identifying the use of the Code in nursing publications may reveal new applications of the Code useful for revision and development of codes of ethics.
History of the code of ethics for nurses with interpretive statements
In 1950, ANA formally adopted a Code for Professional Nurses written to establish principles of conduct for the profession and outlined the nurse–patient relationship, nurse–physician relationship, and nurse–profession relationship. This Code contained 17 declarative provisions including topics such as the responsibility to conserve life, patient abandonment, respect for patient’s religious beliefs, confidentiality, and inter-professionalism. In responses to changes in society, changes in nursing education and practice, and advances in technology and science, two versions of the Code were published in the 1960s, which shifted the focus from conservation of life to deeper obligations respecting human dignity and safeguarding patient’s rights to privacy. An increasing awareness of the nature and determinants of global health contributed to the succeeding iterations (1976 and 1985). Interpretive statements were added to each of the provisions and gave greater depth and a broader duty to contribute to the professional body of knowledge. Continuing education and competence with an increased focus on inter-professionalism were added. By the early 2000s, the concept of compassion was emphasized and a renewed commitment to patients, families, and communities was included. The duty to self, which was dropped out of the Code after the 1960s, was also renewed focusing on nurses’ moral duties of self-respect, preservation of wholeness of character, and sound ethical decision making.
Previous research of the use and the impact of nurses’ professional codes
Previous research on nurses’ professional codes of ethics has mainly focused on nurses’ awareness and use of codes. 12 In clinical practice, nurses’ adherence to the codes seems to be high, 13 although several barriers to following the codes have been identified 14 including individual attributes and organizational factors. 15 Also, international comparison of the use and understanding of the content of nurses’ codes, 16 interdisciplinary reflection, and theoretical analysis of the functions of the codes has been carried out.17–19 Additionally, the impact of professional codes of ethics has been investigated in several other fields, for example, in mobile journalism, 20 biology, 21 and eco-system survival. 22
In health care, the impact of professional codes has been considered when identifying how they support nursing practice 23 and the status of the nursing profession in society.4,24,25 There are also examples of the impact of codes of ethics identified in tele-health practices, 26 midwifery, 27 facilitation of the use of technology, 28 and in collegial relationships. 29 The impact has also been considered in relation to nursing management, use of resources and quality of care, 30 ethical leadership, 31 and ethical international nurse recruitment. 32 In nursing education, codes of ethics are used especially for teaching and learning professionalism, ethical practice, professional values, and learning ethical action.11,18 The importance of codes of ethics in clinical practice and work life is emphasized in the literature.14,25
The use and impact of codes of ethics can be considered directly and indirectly. Directly, how they unify and support nurses’ practice, research, and administration. Indirectly, as the description and reflection of nursing practice. Impact can be seen as multidimensional, including the use in different contexts, and also as the outcomes and consequences of the use. Outcomes can be identified based on scientific research (e.g., Reference 33) and in narratives among professionals and professions. 34 Indirect impact refers to how the codes have been used as a part or a tool of research and how often they have been cited, recognized, and considered.
Aim
The aim of this review was to determine the use and impact of the American Nurses Association Code of Ethics for Nurses with Interpretive Statements. The purpose of the review was to increase understanding of the use and impact of the Code to provide evidence for further development and revision of the Code and other national and international codes of ethics in response to new challenges in nursing practice, research, policy, and education.
The research question was as follows:
— How has the use and impact of the Code been described in nursing publications?
Method
We used a scoping review based on the methodological framework by Arksey and O’Malley’s
35
to explore literature referring to or discussing the Code (Figure 1) following five stages of the method: identifying research questions and relevant papers, selecting the papers, charting the data and collating, summarizing, and reporting the results. The review follows the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) extension for Scoping Reviews.

Identification of research questions and relevant publications
We identified the research question based on preliminary literature searches to guide the search strategy 35 focusing our research question to identify non-scientific and scientific publications available in electronic databases. No previous reviews were found. Next, we carried out electronic searches using CINAHL and PubMed databases covering the literature in nursing and related fields. We used Boolean operator to formulate our search phrase as follows: (ANA OR “American nurse* association”) AND (”code* of ethics” OR “ethical code*”) limiting our searches to publications published between January 2001 and November 2022 in the English language. The purpose was to analyze the use and impact of the Code over a time period covering two revisions, in 2001 and 2015, of the Code due to changes in nursing practice, advances in technology, societal changes, and expansion of nursing practice into advanced practice roles, research, education, health policy, and administration during these years. 2
Selecting publications
We selected publications based on full texts and using inclusion and exclusion criteria. We included publications that mentioned the Code or a section of it anywhere in the text. We excluded publications representing codes of ethics of an organization other than ANA and if the ANA was mentioned only as an affiliation or as a name of an author. Our searches yielded 1739 publications and after removing duplicates (

Results
Based on our literature searches, we selected 785 non-scientific and 71 scientific publications for data. Non-scientific articles fell into seven and scientific articles into five main categories concerning nurses’ professional activities described in the analyzed publications the context of the Code, in which emphasis was in professional ethics and good care, and nursing practice (Table 2). The most frequently and the least referred provisions were in the same line emphasizing immediate nurse–patient relationship, whereas the nurse’s larger societal and researcher roles were less in focus (Table 1).

Discussion
This scoping review analyzed the use and impact of nurses’ codes of ethics focusing on the American Nurses’ Association Code of Ethics (the Code) as an example. 2 The Code has been updated periodically due to changes in practice, technology, emerging concerns, and societal development, both nationally and globally. 2 The literature comprised non-scientific and scientific publications covering the years 2001–2022 and addressing a heterogenous group of nursing fields, topics, and nursing contexts. Use of non-scientific and scientific literature produced two kinds of knowledge of the Code’s impact: empirical research and theoretical analyses are needed to support the codes’ evidence-based development and use, while not underestimating the impact of non-scientific literature as the reflection of nurses’ daily practice concerns in revising nurses’ codes of ethics.106,107
In the publications, the main focus was on professional ethics and good care, suggesting a conventional approach in the use and impact of the codes. Interest in direct patient care and professional ethical issues emphasized care on micro- and meso-level nursing. 4 This finding conforms with earlier studies of the primacy of nurses’ work orientation concentrating on the nurse–patient relationship in clinical settings. 108 Less attention was paid to larger social or leadership issues which would point to macro-level nursing care.4,109,110 However, as the largest group of health care professionals globally, 4 we need to critically analyze factors that promote or prevent nurses’ fulfilling their societal mandate, and consequently its impact. The mandate is clearly expressed in most nurses’ codes of ethics.1,2,4 Nurses’ codes of ethics have both internal and external functions. However, there is little knowledge of how the codes are reflected outside the profession and in collective decision making. This knowledge is important to assess the impact of the codes of ethics on patient care from a wider perspective. Particular attention should focus on nurses who, based on their professional position, are expected to look at nursing from larger perspectives. Professional values were studied rather systematically using versions of Nurses Professional Value Scale 46 comprising factors of caring, activism, trust, professionalism, and justice 46 based on the Code. These value studies are a good example of systematic research in nursing ethics. Many ethical areas in nursing, including codes of ethics, beg for developing instruments and interventions and investing in multifaceted research designs. 111 In issues concerning nursing practice, work environment, and nurses’ working life, the impact of the Code was mainly seen as a guide and support for deliberate problematic issues.6,46,63 Education and research were less in focus. Because publications did not directly focus on teaching codes of ethics, the importance of education may be underestimated in the reviewed literature. Several empirical studies used nursing students as participants, in which importance of teaching codes of ethics was brought up as an essential element of ethics education, as it has been for a long time (e.g., References 24, 112, and 113). As to research, the findings are in line with many studies indicating nurses’ limited use of research in guiding their practice or participating in research activities.1,2,114
Critical discussion of the Code was quite modest (e.g., Reference 42). The codes can be questioned if and how they guide the nursing profession. They should be practiced, not only talked about.11,115 Research has shown that many barriers, such as personal and organizational factors, prevent their use.12,14,109 Furthermore, codes of ethics are known to have several common limitations, such as weaknesses in philosophical foundations, their normative and prescriptive nature, or their minimal impact on moral behavior. The first refers to argumentation from authority and arbitrary choice of values, the second to morality being more than a set of rules, and the last suggesting that the codes do not necessarily impact moral behavior.116,117 Even the claim that codes can be replaced with laws and other documents regulating health professions has been suggested. 118 However, as a caring profession, codes of ethics are seen as fundamental for nursing, supporting the good of patients. This fundamental meaning is still important and relevant. 24 As a normative set of rules, codes of ethics define what is regarded as right and good in nursing. These definitions need revision from time to time. For example, today’s serious global challenges, such as the COVID-19 pandemic and environmental changes, have huge implications for the nursing profession in identifying new ethical goals. These goals clearly involve a need for participating in society to secure healthy living conditions for future generations on the earth 119 by environmentally responsible ways of practicing nursing. 120
Furthermore, global immigration continues to bring up new cultural challenges requiring complex responses from nurses in all settings not forgetting the internationalization of nursing workforce itself. It raises the question of the need of developing global codes of ethics for nurses in which the profession’s basic ethical principles and values are expressed and appreciated in every country and every situation at all levels of nursing care including care cultures in countries in which ICN code of ethics is not in use. In this, the new Code of Ethics of International Council of Nurses1,2 and all national codes including the ANA Code provide a good starting point for collaboration utilizing both evidence-based scientific knowledge as well as knowledge from nursing practice published in professional journals in analyzing the use and impact of the codes of ethics and in developing global approach to the codes for the best of patients and nurses themselves. However, due to differences between countries and their care cultures we should not undermine the value of national codes. They bring ethical issues in professional practice visible, respond to societal needs concerning ethical issues in health care, and reflect the basic function of the profession as well as strengthen the profession’s justification to provide nursing care.121,122
Limitations and future research
There are some minor limitations in this scoping review concerning the focus, literature searches, and data analysis. One limitation is focusing the review on the code of ethics of one nursing organization. However, that enabled us to examine the extent, range, and nature of publication activity around a limited topic in the codes that has not been comprehensively reviewed before. 35 In the future, the use and impact of nurses’ codes of ethics needs more extensive research focusing also on national codes of smaller countries and their comparison. In addition, comparative research between national codes and other health care professions’ codes of ethics might reveal common perspectives for decision making in shared ethical dilemmas.
We limited our literature searches to the English language because presumably most writing of the ANA code is in English. From the viewpoint of international readership, English is also the lingua franca of science. Furthermore, our resources were limited to allow the use of translation services. The time limitation of data was based on over a time period covering two revisions, in 2001 and 2015, of the Code due to changes in nursing practice, advances in technology, societal changes, and expansion of nursing practice into advanced practice roles, research, education, health policy, and administration during these years. 2 These limitations could be a risk that potentially relevant publications could have been missed. However, our data was large and heterogenous, consisting of both non-scientific and scientific publications covering a rather long time period. However, the scoping review method enabled us to map multiple data and present it in a summarized format. 35
The findings of this review represent two levels of evidence, that is, professional and research-based. As a source of knowledge, these levels are differing in value. 38 However, this division was justified to obtain knowledge both from the worlds of nursing practice and nursing science to get a comprehensive description of the use and impact of nurses’ codes of ethics for their future analysis and development. However, this approach caused some limitations. Due to a large number of non-scientific publications, only their main content was analyzed, however, demonstrating their impact and expressing nursing’s interest in informing about the codes. Perhaps more strict inclusion criteria for non-scientific articles would have allowed their deeper analysis, for example, selecting only professional articles published by ANA. Furthermore, it should be also noted that the yearly number of scientific publications was fairly scarce taking into account the time span of over two decades they covered rendering their findings rather scattered.
The focus solely on the Code unavoidably provides an American perspective to nurses’ codes of ethics. Therefore, comparative research between national codes in terms of similarities and differences in developing more uniform codes of ethics for nurses globally would be welcome. In this vein, relating to the Code of International Council of Nurses as a root of most nurses’ codes of ethics would be a natural approach to bring the Code and ICN code and all national codes of nurses even closer to each other.
The use and impact of nurses’ codes of ethics needs more extensive research focusing also on national codes of individual countries and their comparison. Comparative studies among other health care professions’ codes of ethics might reveal common perspectives for decision making in shared ethical dilemmas. 12 Research is needed on factors influencing internalization of the codes 15 and how the emphasis of nurse–patient relationship correlates with social justice, policy issues, and obligations (e.g., Reference 123). Methodologically, long-term research on specific code-related phenomena and analyses from various perspectives with multiple methods might provide new viewpoints and is still topical.15,124
Conclusion
This study analyzed the use and impact of the Code of Ethics for Nurses with Interpretive Statements (the Code) published by the American Nurses Association on nursing, selecting it as one of the oldest and largest codes of ethics in nursing. Findings indicate the main emphasis is on the direct nurse–patient relationship, despite the Code’s guidance to get nurses involved in larger social and global issues. Education, leadership, and research were not found to be priorities. Further research of the meaning and impact of nurses’ codes of ethics is needed based on this analysis to understand the codes’ relevance to nurses. In many countries, nurses’ national codes of ethics are under development. Hopefully, this review provides new perspectives for the creation and revision of nurses’ codes of ethics and innovative ideas for further research.
