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

824
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

1.5K
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,...

Area of Science:

  • Health Informatics
  • Blockchain Technology
  • Data Security

Background:

  • Electronic Health Records (EHR) systems face challenges due to data silos from different vendors, leading to fragmented medical information.
  • Difficulties in inter-institutional EHR sharing, privacy leakage risks, and limited patient control over data usage hinder current healthcare services.

Purpose of the Study:

  • To propose a secure EHR sharing model addressing data fragmentation, privacy concerns, and patient control issues.
  • To enhance the security, privacy, and operational efficiency of EHR systems through a novel blockchain-based approach.

Main Methods:

  • A hybrid storage scheme combining Interplanetary File System (IPFS) with consortium blockchain for improved EHR data security and privacy.
  • Implementation of unidirectional multi-hop conditional proxy re-encryption and distributed key generation for fine-grained EHR access control and traceability.
  • Development of a dynamic Byzantine fault-tolerant algorithm based on reputation and clustering to optimize consensus efficiency.

Main Results:

  • The proposed model effectively improves EHR data security, privacy protection, and operational efficiency.
  • Secure EHR sharing with fine-grained control and traceability of data usage is achieved.
  • The dynamic Byzantine fault-tolerant algorithm enhances consensus efficiency, addressing limitations of traditional PBFT.

Conclusions:

  • The consortium blockchain-based EHR sharing model offers a secure, efficient, and privacy-preserving solution for fragmented healthcare data.
  • The model provides enhanced user control and traceability, addressing key challenges in current EHR systems.
  • The approach demonstrates reduced communication overhead and time consumption, making it suitable for practical implementation.
