Integrated Healthcare System01:20

Integrated Healthcare System

1.8K
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,...

Ethical Standards I01:25

Ethical Standards I

995
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,...

Issues And Trends In Healthcare Delivery System

5.9K
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...

Secondary Healthcare System01:11

Secondary Healthcare System

1.6K
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:

  • Cybersecurity
  • Healthcare Technology
  • Cryptography

Background:

  • The increasing reliance on cloud computing and the Internet of Medical Things (IoMT) in healthcare infrastructure (CHI) necessitates robust data security and privacy measures.
  • Healthcare systems are frequent targets for cyberattacks, with millions of compromises reported annually, highlighting the urgent need for enhanced security protocols.

Purpose of the Study:

  • To propose a secure and lightweight authentication scheme (RAPCHI) for cloud-healthcare infrastructure (CHI) utilizing the Internet of Medical Things (IoMT).
  • To ensure the confidentiality and integrity of patient data in remote healthcare settings, especially during pandemics.

Main Methods:

  • Developed a novel authentication scheme (RAPCHI) based on cryptographic primitives.
  • Validated the formal security analysis of RAPCHI using the random oracle model (ROM) and two alternative approaches.
  • Assessed the scheme's resistance to man-in-the-middle and replay attacks using the AVISPA simulation program.

Main Results:

  • The proposed RAPCHI scheme demonstrates superior security compared to existing frameworks.
  • RAPCHI is highly resistant to a wide range of security threats, including man-in-the-middle and replay attacks.
  • The scheme is computationally and communicationally lightweight, making it suitable for real-world deployment.

Conclusions:

  • The RAPCHI scheme provides a secure, efficient, and robust solution for authentication in cloud-healthcare infrastructure (CHI) leveraging IoMT.
  • The findings suggest RAPCHI is a viable and practical choice for enhancing data security and patient privacy in modern healthcare systems.
