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...

Secondary Healthcare System

1.8K
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...

At the different levels of the healthcare system, we see varying methods of healthcare used. These methods include managed care systems, case management, and primary healthcare.
Managed Care System:
The managed care system is designed to control the cost while maintaining the quality of care. The patient's care from admission to discharge is planned by the primary care provider or the case manager, also known as the gatekeeper. In a managed care system, the number of care providers is...

Integrated Healthcare System01:20

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,...

Summary

This study introduces a consortium medical blockchain system using Possible Byzantine Fault Tolerance to securely share patient data. This blockchain prevents data tampering and leakage, improving medical record integrity and accessibility.

Area of Science:

  • Computer Science
  • Medical Informatics
  • Blockchain Technology

Background:

  • Fragmented medical records hinder patient care and referrals.
  • Current systems lack robust data sharing, anti-tampering, and leakage prevention.
  • Paper-based records are prone to loss and authenticity issues.

Purpose of the Study:

  • To design a secure and shareable medical data system.
  • To address challenges in medical data integrity and accessibility.
  • To propose a novel consortium medical blockchain solution.

Main Methods:

  • Development of a consortium medical blockchain system.
  • Implementation of a Possible Byzantine Fault Tolerance (PBFT) algorithm.
  • Multi-node maintenance and data sharing protocols.
