Applying the Principle of Non-Maleficence in Everyday Nursing Research

The ethical principle of non-maleficence, commonly defined as the obligation to “do no harm,” remains a foundational pillar in nursing research and practice. In contemporary healthcare environments characterized by rapid technological advancements and complex patient needs, ensuring that research activities do not inflict physical, psychological, or social harm is increasingly critical. This study explores how non-maleficence is applied in everyday nursing research contexts and examines its implications for ethical decision-making among nurse researchers. This study employed a literature review research design, systematically examining peer-reviewed articles, policy guidelines, and ethical frameworks published between 2015 and 2025. Databases such as PubMed, CINAHL, and Google Scholar were utilized to identify relevant sources. Inclusion criteria focused on studies addressing ethical principles in nursing research, particularly non-maleficence, while exclusion criteria eliminated unrelated or outdated materials. The selected literature was analyzed using thematic synthesis to identify recurring patterns and key insights. Findings reveal that non-maleficence is operationalized through rigorous risk assessment, informed consent processes, confidentiality safeguards, and ethical review board compliance. Studies highlight that nurse researchers often encounter dilemmas in balancing research benefits with potential risks, particularly in vulnerable populations. The integration of ethical training and institutional oversight mechanisms significantly enhances adherence to non-maleficence. Furthermore, emerging digital health research introduces new ethical challenges, requiring adaptive strategies to prevent harm. The application of non-maleficence in nursing research is both a moral obligation and a professional standard that safeguards participant welfare. Strengthening ethical competence, promoting continuous education, and reinforcing institutional policies are essential to uphold this principle. Ultimately, embedding non-maleficence in all stages of research fosters trust, integrity, and the advancement of safe, patient-centered nursing science.
