Ethical Standards I

804
The American Nurses Association (ANA) created and implemented the first nationally accepted Code of Ethics for Nurses with Interpretive Statements. The Code of Ethics is a living document regularly updated by the ANA and establishes an ethical standard that is non-negotiable for nurses in all roles and settings.
The Code of Ethics provisions outline the nurse's duty to the patient, the healthcare team, the profession, and society. The Code's fundamental principles include advocacy,...

An integrated healthcare system (IHS) is a set of organizations that provides for or arranges to provide coordinated and continuous service to a defined population. The IHS takes responsibility for that particular population's health status and outcome, both clinically and fiscally. An integrated healthcare system is a well-organized, well-coordinated, and collaborative network. The integrated delivery system is a network that connects different healthcare providers to deliver organized,...

Area of Science:

  • Health Informatics
  • Blockchain Technology
  • Cybersecurity

Background:

  • Electronic health records (EHRs) are crucial for health information exchange (HIE).
  • Balancing privacy preservation and data usability in HIE systems remains a challenge.
  • Traditional HIE systems often struggle to meet both security and accessibility needs.

Purpose of the Study:

  • To propose a novel searchable blockchain-based HIE system.
  • To enhance privacy preservation while improving the usability of EHRs.
  • To address the trade-off between security and data usability in HIE.

Main Methods:

  • Users collect healthcare information (HI) from Internet of Medical Things (IoMT) devices.
  • HI is compiled into EHR blocks and shared on a blockchain network.
  • A searchable mechanism is implemented for efficient data retrieval.

Main Results:

  • The proposed system effectively mitigates issues found in traditional HIE systems.
  • Secure and user-friendly access to EHRs is provided.
  • A balance between security and data usability in EHRs is achieved.

Conclusions:

  • The searchable blockchain-based HIE system successfully resolves the security-usability dilemma.
  • This approach offers a robust solution for modern healthcare data exchange.
  • Enhanced privacy and data utility are key benefits of the proposed system.
