Issues And Trends In Healthcare Delivery System

Issues And Trends In Healthcare Delivery System

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

Integrated Healthcare System

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,...

Health Information Technology, commonly called HIT, integrates advanced information systems and technology in healthcare settings. Its primary functions include:

Purpose of Health Records II

Purpose of Health Records II

Health records serve various essential purposes in the healthcare system. Here are some key purposes:

Purpose of Health Records I

Purpose of Health Records I

The vital purpose of health records is to provide a complete and accurate account of a patient's medical history, including communication, diagnostic and therapeutic orders, care planning, research, and quality review.
Here's a breakdown of how health records serve these purposes:

Methods of Documentation VII: EMR

Methods of Documentation VII: EMR

Electronic Medical Records (EMRs) primarily center around electronically documenting patients' health information within a single healthcare organization or practice. They contain essential clinical data related to a patient's medical history, diagnoses, medications, treatment plans, lab results, and other pertinent information relevant to the specific encounter or episode of care. EMRs are designed to streamline documentation and workflow processes within individual healthcare...

Area of Science:

Health Informatics
Blockchain Technology
Data Security

Background:

Electronic Medical Records (EMRs) are sensitive data crucial for patient care.
Current EMR systems face challenges in data sharing, leading to inefficiencies and potential data loss.
Inadequate data privacy, security, and traceability hinder seamless patient transfers between facilities.

Purpose of the Study:

To propose a Hyperledger Fabric-based strategy for improved Electronic Medical Record (EMR) exchange.
To enhance security, privacy, and traceability in medical data sharing.
To introduce a novel medical token system to incentivize EMR data sharing for research.

Main Methods:

Implementation of a Hyperledger Fabric framework for EMR data management.
Integration of Attribute-Based Access Control (ABAC) for granular data access policies.
Utilization of proxy re-encryption to ensure data confidentiality during exchange.
Development of a medical token module for incentivizing data sharing.

Main Results:

The proposed system facilitates secure data sharing among EMR stakeholders via Hyperledger Fabric channels.
Attribute-Based Access Control (ABAC) significantly enhances data access security.
Blockchain immutability ensures data traceability, preventing alteration or destruction of records.
Proxy re-encryption effectively safeguards data privacy during exchange.

Conclusions:

The Hyperledger Fabric-based approach offers a secure and traceable solution for EMR exchange.
The integrated medical token system can encourage patient participation in data sharing for research.
This paradigm promotes collaboration and trust in medical data ecosystems, fostering growth.
