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:

Open and closed-loop control systems

Open and closed-loop control systems

Control systems are foundational elements in automation and engineering. They are broadly categorized into open-loop and closed-loop systems. These classifications hinge on the presence or absence of feedback mechanisms, significantly influencing the system's performance, complexity, and application.
An open-loop control system operates without feedback from the output. It consists of two primary elements: the controller and the controlled process. The controller receives an input signal and...

Methods of Documentation VI: Case Management Model

Methods of Documentation VI: Case Management Model

The case management model is a multidisciplinary approach that involves healthcare professionals from diverse disciplines, such as physicians, nurses, therapists, social workers, and pharmacists, working collaboratively to address the various needs of patients. Each healthcare professional brings unique expertise and perspectives, contributing to a more comprehensive understanding of the patient's condition and tailoring treatment plans accordingly.
For example, a patient with a chronic illness...

Methods Of Healthcare Delivery System

Methods Of Healthcare Delivery System

At the different levels of the healthcare system, we see varying methods of healthcare used. These methods include managed care systems, case management, and primary healthcare.
Managed Care System:
The managed care system is designed to control the cost while maintaining the quality of care. The patient's care from admission to discharge is planned by the primary care provider or the case manager, also known as the gatekeeper. In a managed care system, the number of care providers is limited...

Introduction To Health Care Delivery System

Introduction To Health Care Delivery System

The healthcare system is constantly changing and complex. Various services are available from different healthcare providers, but gaining access to these services has become challenging for people with limited healthcare insurance. Uninsured people present a challenge to healthcare because they frequently postpone or forego treatment.
The Institute of Medicine (IOM) advocates for a patient-centered, effective, safe, timely, equitable, and effective healthcare system. The National Priorities...

Healthcare Associated Infections II: Preventive Measures

Healthcare Associated Infections II: Preventive Measures

Essential infection prevention measures are based on the knowledge of the infection chain, the modes of transmission in healthcare settings, and the use of the best practices in all healthcare settings. Compulsory public reporting of healthcare-associated infection rates is needed to allow individuals and the community to make informed choices regarding selecting a healthcare facility.
The best practices for preventing healthcare-associated infections include hand hygiene, patient risk...

Area of Science:

Critical Care Medicine
Control Systems Engineering
Biomedical Engineering

Background:

Military operations and mass casualty events present unique challenges to immediate medical care providers.
Limited healthcare resources and provider skill gaps can compromise patient management in austere environments.
Existing critical care practices may be overwhelmed by the demands of mass casualty scenarios.

Purpose of the Study:

To explore the application of closed-loop control (CLC) techniques in critical care medicine for austere environments.
To review control system theory relevant to the design of autonomous CLC systems in healthcare.
To introduce developing clinical applications of CLC for deployment in resource-limited settings.

Main Methods:

Review of control system theory principles applied to dynamic physiological systems.
Analysis of feedback mechanisms in monitoring and controlling patient variables.
Exploration of existing and developing CLC systems in various critical care modalities.

Main Results:

Closed-loop control (CLC) demonstrates potential to manage complex patient needs in resource-limited settings.
Potential benefits include reduced provider task saturation, optimized medication titration, and conserved supplies.
CLC may improve patient outcomes by preventing secondary insults and shortening mechanical ventilation duration.

Conclusions:

Closed-loop control (CLC) systems offer promising solutions for enhancing medical care in austere and high-demand environments.
Further development and validation of autonomous CLC systems are crucial for widespread clinical adoption.
The integration of control theory into critical care medicine can significantly improve patient management and resource utilization.
