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,...

Design Example

Design Example

The innovation of touch-tone telephony revolutionized the telecommunications industry by replacing the traditional rotary dial with a dual-tone multi-frequency (DTMF) signaling system. This system uses a matrix-style keypad with buttons arranged in four rows and three columns, creating 12 distinct signals each assigned to a pair of frequencies. Each button press results in a simultaneous generation of two sinusoidal tones – one from a low-frequency group (697 to 941 Hz) and one from a...

Dementia

Dementia

Dementia is a collective term for cognitive disorders primarily affecting memory, thinking, and reasoning. It is not a specific disease but a syndrome, with Alzheimer's disease being the most common cause, accounting for approximately 60-80% of cases. Other types include vascular dementia, Lewy body dementia, and frontotemporal dementia. Dementia affects millions worldwide, particularly older adults, though it is not a normal part of aging.
The progression of dementia is generally gradual.

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:

Dementia l: Introduction

Dementia l: Introduction

Dementia is an acquired, progressive syndrome characterized by a decline in multiple cognitive domains severe enough to impair daily functioning and reduce independence. Although memory loss is a central feature, the diagnosis requires additional deficits involving language, executive function, visuospatial skills, judgment, calculation, or abstract reasoning. These cognitive impairments reflect underlying neurodegenerative or vascular processes that gradually disrupt neuronal networks...

Area of Science:

Gerontology
Assistive Technology
Human-Computer Interaction

Background:

Elderly individuals often face communication challenges due to age-related visual and memory decline.
Traditional mobile phones can be difficult to operate, leading to errors like misdialing.
Existing communication aids may not adequately address the specific needs of seniors.

Purpose of the Study:

To develop and evaluate a user-friendly mobile phone system tailored for elderly users.
To enhance communication accessibility for seniors with visual impairments and memory issues.
To reduce instances of misdialing and communication errors among the elderly population.

Main Methods:

Development of a low-power mobile phone (PHS phone) with a large liquid crystal display.
Implementation of a contact selection interface using registered support personnel pictures.
Automated dialing functionality upon user selection of a contact image.

Main Results:

The system simplifies mobile phone operation for elderly users.
Visual display of contacts aids recognition and verification, reducing errors.
The system effectively assists elderly individuals experiencing poor eyesight and memory limitations.

Conclusions:

The developed mobile communication support system enhances usability for seniors.
This technology can significantly improve communication independence and reduce frustration for elderly users.
The system offers a practical solution for addressing common communication barriers in the elderly population.
