Issues And Trends In Healthcare Delivery System01:29

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...
Tertiary Healthcare System01:21

Tertiary Healthcare System

Specialized care provided over an extended period is called tertiary care. Usually, a primary or secondary care physician will refer a patient to tertiary care. A patient's maximum physical and mental function is restored in tertiary care, which is caused due to the impact of a chronic illness or condition. Tertiary care aims to achieve the highest level of functioning possible while managing chronic illness. For example, a patient who falls and fractures their hip will need secondary care to...
Current Trends in Nursing II01:30

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,...
Acute Respiratory Failure-III01:30

Acute Respiratory Failure-III

Hypercapnic respiratory failure, also known as Type 2 or ventilatory respiratory failure, is a severe condition characterized by the body's inability to effectively remove carbon dioxide (CO2) from the bloodstream. It leads to an arterial CO2 pressure (PaCO2) exceeding 45 mmHg and a blood pH above 7.35. This situation indicates that the body's ventilatory demand, or the ventilation needed to maintain normal PaCO2 levels, surpasses its supply or the maximum gas flow achievable without causing...
Increased Intracranial Pressure l: Introduction01:14

Increased Intracranial Pressure l: Introduction

Intracranial hypertension is a sustained elevation of intracranial pressure (ICP) above 22 mm Hg. In supine adults, normal ICP is ~7–15 mm Hg.The rigid, nonexpandable cranium contains three components—brain tissue, blood, and cerebrospinal fluid (CSF)—that total ~1,700 mL in a typical adult: 1,400 mL brain (~80%), 150 mL blood (~10%), and 150 mL CSF (~10%). According to the Monro–Kellie doctrine, total intracranial volume is effectively fixed. When one component expands, CSF and venous blood...

Summary

Global critical illness burden data is scarce. Estimating this burden and resource disparities requires advanced modeling due to definitional challenges and data limitations.

Area of Science:

  • Global Health
  • Critical Care Medicine
  • Epidemiology

Background:

  • Growing interest in the global burden of critical illness.
  • Lack of comprehensive data on critical illness prevalence and resource availability.

Purpose of the Study:

  • To highlight the challenges in estimating the global burden of critical illness.
  • To identify factors influencing critical care demand and resource allocation.

Main Methods:

  • Discussion of challenges in data collection and case ascertainment.
  • Emphasis on the need for modeling techniques to estimate burden and disparities.

Main Results:

  • Critical illness definitions and equating it with ICU admission pose challenges.
  • Data limitations hinder accurate global burden estimation.
  • Demand for critical care is rising due to demographic shifts and global events.

Conclusions:

  • Significant research gaps exist regarding the worldwide burden of critical illness.
  • Understanding variations in treatment resources is crucial.
  • Developing effective and feasible prevention and treatment strategies is needed.
