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...

Ethical Standards I

Ethical Standards I

The American Nurses Association (ANA) created and implemented the first nationally accepted Code of Ethics for Nurses with Interpretive Statements. The Code of Ethics is a living document regularly updated by the ANA and establishes an ethical standard that is non-negotiable for nurses in all roles and settings.
The Code of Ethics provisions outline the nurse's duty to the patient, the healthcare team, the profession, and society. The Code's fundamental principles include advocacy,...

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:

Health Information Technology and Healthcare Information System

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

Healthcare Agencies I

Healthcare Agencies I

Healthcare agencies provide healthcare services to people. In the United States, voluntary agencies are often non-profit centers sponsored by donations, grants, or fundraisers. One such organization is Meals on Wheels, which provides meals to the elderly and homebound. The American Heart Association and the American Lung Association are other non-profit community organizations. Doctors and nurses are frequently active members of these organizations, which offer health checks and educational...

Area of Science:

Health Informatics
Blockchain Technology
Data Management

Background:

Electronic Healthcare Records (EHRs) are fragmented across facilities, creating data silos and safety risks.
Existing systems lack clinical context presentation, hindering effective data utilization.
Need for secure, interoperable, and patient-centric EHR management solutions.

Purpose of the Study:

To design and implement a blockchain-based platform for EHR provenance tracking.
To ensure compliance with healthcare standards and patient-informed consent.
To address challenges in EHR interoperability and clinical context.

Main Methods:

Leveraged international standards: Integrating the Healthcare Enterprise (IHE), Health Level Seven International (HL7), and Fast Healthcare Interoperability Resources (FHIR).
Developed a blockchain platform using Hyperledger Fabric with a smart contract for W3C PROV management.
Integrated a Java Proxy for intercepting document submissions/retrievals and a service for PROV document retrieval.

Main Results:

Successfully integrated the decentralized platform with the SpiritEHR engine and a CDA repository.
Observed minimal processing time overhead (milliseconds) for data reading/writing using a cloud-based blockchain.
Demonstrated transparent usage of provenance data for decision-making, data reconciliation, and consent auditing.

Conclusions:

A blockchain-based solution effectively manages EHR provenance, enhancing data integrity and security.
The platform integrates seamlessly into routine healthcare operations using international standards.
This approach facilitates transparent data management, respecting patient consent preferences.
