Nursing Clinical Information System

Nursing Clinical Information System

Nursing Clinical Information System (NCIS)
A Nursing Clinical Information System (NCIS) is a specialized type of healthcare information system tailored to meet the unique needs of nursing practice. It incorporates the principles of nursing informatics to streamline information management and improve the quality of care delivery.
Critical attributes of NCIS include:

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,...

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,...

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 settings,...

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...

Area of Science:

Biomedical Engineering
Computer Science
Network Security

Background:

Wireless medical sensor networks (WMSNs) enable remote patient monitoring but face significant security vulnerabilities.
Protecting sensitive patient physiological data from unauthorized access is critical for WMSN deployment.
Current authentication methods in WMSNs may not adequately address the unique security challenges.

Purpose of the Study:

To propose an efficient and strong authentication protocol, named E-SAP, for healthcare applications utilizing WMSNs.
To enhance the security of patient data transmission in WMSNs.
To ensure robust user authentication for healthcare professionals interacting with WMSNs.

Main Methods:

Developed the Efficient and Strong Authentication Protocol (E-SAP) for WMSNs.
Implemented two-factor authentication (password and smartcard) for professionals.
Incorporated mutual authentication between professionals and medical sensor nodes.
Utilized symmetric encryption/decryption for message confidentiality and established secure session keys.
Designed a protocol with three message exchanges for efficiency.

Main Results:

E-SAP provides strong authentication through two-factor and mutual authentication mechanisms.
The protocol ensures message confidentiality and establishes secure session keys.
E-SAP demonstrates efficiency with low computation and communication costs.
Formal, security, and performance analyses confirm E-SAP's robustness against practical attacks.

Conclusions:

E-SAP offers a secure and efficient solution for authentication in WMSNs for healthcare.
The protocol effectively protects sensitive patient data from unauthorized exposure.
E-SAP allows for a flexible tradeoff between security and performance costs in healthcare WMSN applications.
