Current Trends in Nursing II

Current Trends in Nursing II

Trends in nursing are multifactorial and associated with changes in society, within the nursing profession, and in other professions. Notably, telehealth and remote nursing contribute to successful healthcare delivery for numerous patients and help reduce stress for nurses due to nursing shortages. Nurses can reach patients, monitor their conditions, and interact with them using computers, audio, visual accessories, and telephones—for example, remote patient monitoring systems. Likewise,...

Atherosclerosis IV: Nursing Management

Atherosclerosis IV: Nursing Management

Nursing management for a patient with arteriosclerosis involves a comprehensive approach focusing on lifestyle modification, disease monitoring, education, and symptomatic care. Here is an overview of effective nursing strategies:Assessment and Monitoring: Initial and ongoing assessments are crucial. Nurses must document the patient's medical history, including any hypertension, diabetes, hyperlipidemia, and other cardiovascular diseases. Assessments also cover family history and lifestyle...

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:

Nursing Implementation

Nursing Implementation

Implementation is the execution of the nursing care plan developed during the planning phase.
The five steps to implementing effective nursing care include reassessing the patient, reviewing and revising the existing nursing care plan, organizing the resources and care delivery, anticipating and preventing complications, and implementing nursing interventions.

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...

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...

Area of Science:

Healthcare technology
Wireless sensor networks
Edge computing

Background:

Wireless Body Area Networks (WBANs) are crucial for remote healthcare monitoring but face limitations in storage and computation.
Massive sensor data overwhelms WBANs, decreasing efficiency and reliability.
Mobile Edge Computing (MEC) offers a solution to offload computation from WBANs.

Purpose of the Study:

To address the challenges of limited WBAN resources in healthcare.
To jointly optimize computational offloading and resource allocation (JCORA) in MEC for WBANs.
To reduce time delay and energy consumption in interfered transmission channels.

Main Methods:

Formulated the JCORA problem as a Markov decision process.
Proposed a Deep Deterministic Policy Gradient-based WBAN Offloading Strategy (DDPG-WOS).
Optimized offloading decisions considering channel conditions, transmission quality, computation ability, and energy consumption.

Main Results:

The DDPG-WOS effectively mitigates computation pressure on WBANs.
The proposed scheme enhances transmission capabilities by utilizing MEC.
Simulation results demonstrate significant reductions in energy consumption and computation latency.

Conclusions:

The DDPG-WOS strategy improves the overall utility of WBANs in healthcare scenarios.
The proposed optimization schema outperforms competitive solutions.
MEC integration with WBANs is a viable approach for efficient remote healthcare monitoring.
