Summary
Interpersonal and individual factors significantly influence patients' informed consent, while organizational and environmental aspects are more affected. Enhancing communication is key for healthcare system improvement.
Area of Science:
- Medical Ethics
- Healthcare Management
- Patient Rights
Background:
- Informed consent is crucial for ethical medical practice and patient autonomy.
- Inadequate informed consent processes can compromise healthcare system integrity.
- Understanding the interplay of factors influencing informed consent is essential.
Purpose of the Study:
- To analyze the systematic relationships among factors affecting patients' informed consent.
- To identify key influential and influenced factors in the informed consent process.
- To develop a model for understanding informed consent dynamics in healthcare.
Main Methods:
- Descriptive-analytical cross-sectional study conducted in a private Tehran hospital.
- Purposive and snowball sampling of 11 specialist physicians and nurses.
- Data collected via pairwise comparison matrix questionnaire, analyzed using SPSS and DEMATEL method in MATLAB.
Main Results:
- Interpersonal and individual factors were identified as the primary influencers of informed consent.
- Organizational and environmental factors were found to be the most influenced.
- Interpersonal factors emerged as the most influential, and environmental factors as the most influenced.
Conclusions:
- A DEMATEL-based model highlights interpersonal and individual factors as key drivers of informed consent.
- Improving communication quality and patient understanding can yield system-wide benefits.
- Findings are exploratory, originating from a single hospital, providing a basis for future research in similar settings.

01:27Nurses' Legal Responsibilities I
In healthcare, informed consent is a crucial process that involves thoroughly communicating medical treatment options to patients, including benefits, risks, potential side effects, and alternatives. This process enables patients to make well-informed decisions about their care, ensuring they understand the implications of their choices before consenting to or refusing treatment.
The legal responsibilities of a nurse regarding informed consent include the following:

01:56Ethics in Research
Today, scientists agree that good research is ethical in nature and is guided by a basic respect for human dignity and safety. However, this has not always been the case. Modern researchers must demonstrate that the research they perform is ethically sound.
01:30Ethical Dilemmas II
Resolving an ethical dilemma in healthcare involves a systematic approach that considers every aspect of the issue, respecting both the patient's needs and values and the healthcare professional's ethical obligations. Here are potential steps to resolve an ethical dilemma:
01:22Ethics and Bioethics
Ethics is a philosophical study of moral actions. Ethics attempts to determine what is valuable for individuals and society. It examines the rational justification of moral judgments and analyzes what is morally just, fair, and right. Bioethics is a sub-discipline of applied ethics that analyzes the philosophical, social, and legal issues in life sciences and medicine. Ethical theories serve as a foundation for decision-making and represent the viewpoints from which people seek direction. They...
01:03Data Validation
Data validation is an essential part of a comprehensive assessment. Validation is confirming or verifying and opening the door to gathering more assessment data as it clarifies vague or unclear data. The process of checking and verifying the collected information is called data validation. The primary purpose of data validation is to ensure data is as free from error, bias, and misinterpretation as possible.

01:23Types of Biopharmaceutical Studies: Controlled and Non-Controlled Approaches
Biopharmaceutical studies constitute a vital field aiming to enhance drug delivery methods and refine therapeutic approaches, drawing upon diverse interdisciplinary knowledge. In research methodologies, the choice between controlled and non-controlled studies significantly influences the study's reliability and accuracy.
Non-controlled studies, commonly employed for initial exploration, lack a control group, rendering them susceptible to biases and external influences. In contrast, controlled...
