Issues And Trends In Healthcare Delivery System

5.7K
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...

Integrated Healthcare System

1.7K
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:

  • Computer Science
  • Information Security
  • Healthcare Technology

Background:

  • Current internet protocols lack robust digital identity management (DIM), posing privacy and security risks.
  • Blockchain technology presents a decentralized solution for secure data management and identity verification.
  • Concerns about sensitive data handling and storage are rising, particularly for e-health services.

Purpose of the Study:

  • To review the state-of-the-art in blockchain-based decentralized identity management (DIM) for healthcare.
  • To provide insights into the application of blockchain DIM frameworks for virtualized healthcare.

Main Methods:

  • A scoping, semi-systematic review approach was employed.
  • Seven identity management systems were evaluated based on autonomy, authority, availability, approval, confidentiality, tenacity, and interoperability.

Main Results:

  • Seven blockchain-based identity management systems were analyzed.
  • Evaluated systems utilized platforms such as Ethereum, Hyperledger Indy, Hyperledger Fabric, Hedera, and Sovrin.

Conclusions:

  • Digital identity management (DIM) is essential for virtual healthcare.
  • Blockchain-based DIM for healthcare is an active area of research and development.
  • Further research is needed to optimize DIM efficiency and identify suitable technical frameworks for e-health.
