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...

Applications of GIS: Disaster Management and Emergency Response

143
Geographic Information System (GIS) technology is essential for risk identification, action prioritization, and resource optimization in critical situations like flooding and earthquakes. By integrating spatial and demographic data, GIS provides a comprehensive framework for emergency response.GIS integrates data layers, like rainfall intensity, topography, elevation profiles, and river levels, to model high-risk flood zones. These layers assess areas susceptible to flooding based on their...

Primary care promotes wellness and prevents disease. This care includes health promotion, education, protection (such as immunizations), early disease screening, and environmental considerations. Settings providing this type of healthcare include physician offices, public health clinics, school nursing, and community health nursing.
In 1978, international leaders convened in Alma-Ata, Kazakhstan, for what would be a pivotal event in global health. The Alma-Ata Declaration was the first to call...

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,...

Geographic Information Systems (GIS) rely on two core types of data: spatial data and attribute data.Spatial DataSpatial data defines the physical location of features within a coordinate system, typically expressed in terms of latitude and longitude. It provides precise positioning for elements like roads, rivers, or buildings.Attribute DataAttribute data complements spatial data by adding descriptive information about these features. For example, a road's spatial data includes its start and...

Area of Science:

  • Computer Science
  • Internet of Things (IoT)
  • Blockchain Technology
  • Smart City Applications
  • Public Emergency Services (PES)

Background:

  • Existing smart city applications often prioritize healthcare, neglecting distributed fire brigade systems as public emergency services (PES).
  • Traditional centralized PES suffer from high computation demands, lack of trust, transparency, data integrity, and single points of failure.
  • There is a critical need for a secure, transparent, and efficient PES for fire response in smart homes.

Purpose of the Study:

  • To propose a novel Blockchain-Enabled Secure and Trusted (BEST) framework for public emergency services (PES) in smart cities.
  • To specifically enhance fire brigade response systems for smart homes using IoT and blockchain.
  • To address the limitations of traditional centralized PES by introducing a distributed and trustworthy system.

Main Methods:

  • Development of the Blockchain-Enabled Secure and Trusted (BEST) framework utilizing IoT devices and edge computing.
  • Implementation of an IoT controller for access control and a service controller employing a queue model for efficient request handling.
  • Design and deployment of smart contracts on the Hyperledger Fabric platform for automated PES activation under uncertain conditions.

Main Results:

  • The BEST framework demonstrates the advantages of a distributed environment and smart contract logic for PES.
  • Performance evaluation shows improvements in service queue length, utilization, and reduced end-to-end delay.
  • Simulation results confirm the effectiveness and feasibility of the proposed framework for smart home fire emergencies.

Conclusions:

  • The proposed BEST framework offers a secure, transparent, and efficient solution for distributed smart fire brigade systems.
  • Blockchain technology and edge computing significantly enhance the reliability and performance of public emergency services (PES).
  • The framework effectively addresses critical issues in traditional PES, paving the way for safer smart cities.
