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 System01:20

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,...

Secondary Healthcare System

1.5K
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.

Area of Science:

  • Health Informatics
  • Computer Science
  • Blockchain Technology

Background:

  • e-Healthcare systems face challenges with interoperability, stability, and scalability due to increasing user demands and data complexity.
  • Existing HL7-FHIR frameworks often rely on REST-API, which can be complex, time-consuming, and violate quality-of-service (QoS) standards.

Purpose of the Study:

  • To develop a robust and interoperable e-Healthcare solution using a novel Smart-Contract Authentication Assisted HL7-FHIR framework.
  • To address the limitations of traditional REST-API based FHIR frameworks in meeting QoS demands for large-scale e-Healthcare.

Main Methods:

  • The proposed framework utilizes a Graph-mapping concept to transform FHIR resource variables into Graph-Mapped Data Structures (GMS).
  • Data is stored in a NoSQL MongoDB database, and a Smart Contract is employed for user authentication and secure electronic health record (EHR) exchange.
  • Key components include the GMS-driven HL7 FHIR Gateway Model, Smart Contract Authentication, and Client Model.

Main Results:

  • The novel framework significantly reduces computational time and optimizes resource utilization compared to classical REST-API based FHIR.
  • The Smart Contract effectively verifies and authenticates users, ensuring privacy and security in EHR exchange.
  • The proposed model demonstrates improved performance, meeting QoS demands for e-Healthcare.

Conclusions:

  • The developed Smart-Contract Authentication Assisted HL7-FHIR framework offers a viable and efficient solution for enhancing e-Healthcare interoperability.
  • This approach addresses critical challenges in scalability, stability, and secure data exchange, improving real-world e-Healthcare mechanisms.
