Issues And Trends In Healthcare Delivery System

5.6K
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...

Methods of Documentation VII: EMR

832
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...

Integrated Healthcare System

1.6K
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,...

Secondary Healthcare System01:11

Secondary Healthcare System

1.5K
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...

Area of Science:

  • Health Informatics
  • Cybersecurity
  • Blockchain Technology

Background:

  • Securing sensitive medical records in cloud environments is a critical challenge.
  • Existing electronic health record (EHR) systems often lack robust patient control and data integrity.
  • Decentralized storage and advanced encryption are needed to enhance healthcare data security.

Purpose of the Study:

  • To propose and evaluate an End-to-End Encryption (E2EE) enhanced patient-centric blockchain system for EHR management.
  • To enable patients to control access to their medical records.
  • To ensure the integrity and security of EHR data stored in the cloud.

Main Methods:

  • Utilizing a patient-centric blockchain system with Ethereum for EHR management.
  • Implementing Inter-Planetary File System (IPFS) for decentralized and immutable record storage.
  • Applying dual-level hybrid encryption: Advanced Encryption Standard (AES) and Elliptic Curve Cryptography (ECC).

Main Results:

  • The proposed system demonstrates superior performance compared to existing cutting-edge systems.
  • Efficient key generation, encryption, and decryption times were observed for file sizes ranging from 512 KB to 100 MB.
  • The system proved practical for sharing secure health data in cloud environments.

Conclusions:

  • The E2EE enhanced blockchain system offers a secure and patient-controlled solution for EHR management.
  • The integration of IPFS and hybrid encryption ensures data integrity and privacy.
  • The system is a viable approach for enhancing healthcare data security in the cloud.
