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.

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,...

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...

Therapeutic Drug Monitoring: Affecting Factors01:29

Therapeutic Drug Monitoring: Affecting Factors

Therapeutic Drug Monitoring (TDM) is the clinical practice of measuring specific drug levels in a patient's blood or body tissues to manage and optimize therapy. TDM is crucial for drugs with narrow therapeutic windows, like warfarin and phenytoin, where incorrect doses can lead to treatment failure or severe side effects. This monitoring ensures the dosage administered is within a safe and effective range. The factors affecting therapeutic drug monitoring include:Patient-Specific Factors:a.

Area of Science:

  • Radiology
  • Medical Imaging
  • Radiation Protection

Background:

  • Computed tomography (CT) utilization has increased exponentially worldwide over the past 25 years.
  • Significant variability exists in CT utilization and practice patterns across different regions and patient populations (adults and pediatrics).
  • Technical, healthcare, regulatory, and cultural factors influence the use of CT imaging.

Purpose of the Study:

  • To highlight key aspects of pediatric CT radiation protection.
  • To discuss challenges in establishing diagnostic reference levels for pediatric CT.
  • To provide an overview of global trends and practice variations in CT use.

Main Methods:

  • Review of global trends in CT utilization.
  • Analysis of available pediatric CT dose surveys from multiple countries.
  • Discussion of factors influencing CT practice patterns.

Main Results:

  • Exponential rise in CT use globally over the last 25 years.
  • Identified variability in CT utilization and practice patterns in both adult and pediatric populations.
  • Development of proposed diagnostic reference levels for pediatric CT in several countries.

Conclusions:

  • Variability in CT use necessitates targeted approaches to radiation protection.
  • Establishing diagnostic reference levels is a critical step in optimizing pediatric CT doses.
  • Continued focus on radiation protection in pediatric CT is essential globally.
