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...

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:

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:

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:

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...

Background:

Blockchain technology, initially used in finance, shows potential for healthcare due to its data integrity and distribution capabilities.
Personal Health Record (PHR) data management faces challenges with geographical distribution and interoperability.
Existing blockchain applications in healthcare are limited, especially for distributed PHR data.

Purpose of the Study:

To propose and discuss an architectural model for a blockchain platform, OmniPHR Multi-Blockchain, designed to address challenges in distributed PHR data management.
To identify critical barriers in applying blockchain to distributed PHR data through literature analysis.
To present a prototype evaluation of the proposed architecture.

Main Methods:

Literature review to identify challenges in applying blockchain to distributed PHR data.
Development of the OmniPHR Multi-Blockchain architectural model.
Prototype development and evaluation for processing geographically distributed PHR data.

Main Results:

The OmniPHR Multi-Blockchain architecture shows promising results for distributed PHR data scenarios.
The proposed architecture provides a viable and beneficial alternative for processing geographically distributed PHR data.
Performance comparable to conventional methods was achieved, demonstrating effectiveness.

Conclusions:

Blockchain technology offers a robust solution for enhancing the distribution and interoperability of PHR data.
The OmniPHR Multi-Blockchain architecture effectively addresses key challenges in managing distributed health records.
This study empirically validates a novel blockchain-based approach for distributed PHR data processing.
