Issues And Trends In Healthcare Delivery System

5.8K
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

898
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...

Ethical Standards I

944
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
  • Cybersecurity
  • Distributed Ledger Technology

Background:

  • Centralized Electronic Healthcare Record (EHR) systems face challenges in secure data sharing and maintaining patient privacy.
  • Traditional EHR systems are vulnerable to data breaches and regulatory non-compliance due to their centralized nature.
  • The need for robust, secure, and immutable methods for healthcare data exchange is critical.

Purpose of the Study:

  • To propose a novel blockchain-based architecture for secure and authenticated sharing of Electronic Healthcare Records (EHR).
  • To enhance the security, authenticity, and efficiency of healthcare data management by leveraging decentralized ledger technology.
  • To address the limitations of centralized EHR systems regarding safety, isolation, and regulatory adherence.

Main Methods:

  • Implementation of a blockchain architecture utilizing a Proof of Stake (POS) consensus mechanism for user authentication.
  • Integration of Secure Hash Algorithm (SHA256) for securing EHR data transmission and storage.
  • Utilization of Elliptic Curve Digital Signature Algorithm (ECDSA) for verifying EHR sensor data integrity.

Main Results:

  • The proposed blockchain solution demonstrates superior performance in terms of power consumption, authenticity, and security compared to existing methods like Proof-of-Work (POW), SHA-1, and MD5.
  • The system effectively authenticates users and secures EHR sharing across diverse healthcare systems.
  • Data immutability on the blockchain network significantly reduces the risk of data exploitation.

Conclusions:

  • Blockchain technology offers a secure and efficient paradigm for managing and sharing Electronic Healthcare Records (EHR).
  • The proposed POS and SHA256-based architecture provides enhanced security and authenticity for sensitive patient data.
  • This approach represents a significant advancement in overcoming the security and privacy challenges of traditional EHR systems.
