Issues And Trends In Healthcare Delivery System

6.1K
The issues and trends in healthcare delivery are constantly changing. The COVID-19 pandemic is one recent issue that wreaked havoc on healthcare systems, causing a shortage of healthcare workers, high demand for medicines and supplies, and increased medical expenditure due to a lack of insurance. Other issues include rising healthcare costs and care fragmentation.
Cost Containment
Payment for healthcare services has historically promoted adoption of costly and often unnecessary or inefficient...

Methods of Documentation VII: EMR

1.3K
Electronic Medical Records (EMRs) primarily center around electronically documenting patients' health information within a single healthcare organization or practice. They contain essential clinical data related to a patient's medical history, diagnoses, medications, treatment plans, lab results, and other pertinent information relevant to the specific encounter or episode of care. EMRs are designed to streamline documentation and workflow processes within individual healthcare...

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,...

Area of Science:

  • Health Informatics
  • Computer Science
  • Information Security

Background:

  • Data security concerns impede the widespread adoption of electronic health records (EHRs).
  • Blockchain technology offers a decentralized approach to verify transactions, presenting a potential solution for securing health data.

Purpose of the Study:

  • To introduce blockchain technology for EHRs by identifying stakeholder requirements.
  • To discuss the key benefits and challenges of implementing blockchain in EHR systems.

Main Methods:

  • Developed a blockchain-based architecture using the design science research paradigm.
  • Identified stakeholder requirements through literature review and interviews with healthcare experts.
  • Evaluated the proposed architecture via workshops with participants.

Main Results:

  • Identified three major EHR stakeholder groups and 34 requirements.
  • Developed a five-layer blockchain architecture for EHRs.
  • Discussed 12 key benefits and 12 key challenges, with five recommendations provided.

Conclusions:

  • Blockchain technology holds significant potential for advancing EHRs, particularly in data security, traceability, and automation via smart contracts.
  • Further research is recommended on patient acceptance and cost-benefit analyses of blockchain-based EHRs.
