Issues And Trends In Healthcare Delivery System

5.9K
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

2.0K
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,...

Secondary Healthcare System01:11

Secondary Healthcare System

1.7K
Secondary healthcare is offered by a specialist, generally in hospitals or clinics for patients referred by primary healthcare providers. It occurs when a person has an illness or injury that requires specific medical care. Secondary care is often referred to as acute care. Secondary care can range from uncomplicated care to repair a minor laceration or treat a strep throat infection to more complicated emergent care, such as treating a head injury sustained in an automobile accident. Whatever...

Healthcare Agencies I

927
Healthcare agencies provide healthcare services to people. In the United States, voluntary agencies are often non-profit centers sponsored by donations, grants, or fundraisers. One such organization is Meals on Wheels, which provides meals to the elderly and homebound. The American Heart Association and the American Lung Association are other non-profit community organizations. Doctors and nurses are frequently active members of these organizations, which offer health checks and educational...

Role-Based Identity01:21

Role-Based Identity

50
Role-based identities are central to understanding how individuals navigate social environments by adopting distinct self-conceptions aligned with various societal roles. These identities are not fixed traits but are constructed through personal actions and the social feedback individuals receive in context-specific interactions. Each social role, such as student, teacher, or friend, carries a set of expectations and norms that influence how people think, feel, and behave within that...

Area of Science:

  • Health Informatics
  • Blockchain Technology
  • Cybersecurity

Background:

  • The COVID-19 pandemic accelerated the adoption of eHealth and telehealth solutions, increasing efficiency and accessibility in healthcare delivery.
  • Current centralized identity management systems in eHealth applications create data silos, limiting interoperability and user authentication across different platforms.
  • Patients using remote eHealth services lack control and transparency regarding the security and privacy of their identity information.

Purpose of the Study:

  • To introduce a blockchain-based decentralized identity management system for eHealth.
  • To enable secure, transparent, and interoperable identification and authentication for patients and healthcare providers across various eHealth domains.
  • To address the limitations of centralized identity systems in current remote healthcare solutions.

Main Methods:

  • Development of a decentralized identity management system utilizing blockchain technology.
  • Implementation of unique health identifiers (healthIDs) for patients and providers, with attributes attested by a healthcare regulator.
  • Deployment of smart contracts on an Ethereum consortium blockchain to manage identification and authentication processes.
  • Performance analysis using metrics such as transaction gas cost, transactions per second, block loss, and propagation time, with parameter tuning for optimization.

Main Results:

  • The proposed system facilitates transparent and secure identification and authentication across different eHealth domains.
  • Performance metrics were analyzed, and parameters like block-time, gas-limit, and sealers were adjusted for optimal consortium blockchain performance.
  • The system establishes a foundation for enhanced security and privacy in remote eHealth interactions.

Conclusions:

  • Blockchain-based decentralized identity management offers a robust solution to the interoperability and security challenges in eHealth.
  • The developed system empowers patients and providers with secure control over their digital identities in the eHealth ecosystem.
  • Further optimization of blockchain parameters is crucial for achieving efficient and scalable decentralized identity solutions in healthcare.
