Issues And Trends In Healthcare Delivery System01:29

Issues And Trends In Healthcare Delivery System

6.0K
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...

Computed Tomography01:10

Computed Tomography

7.7K
Tomography refers to imaging by sections. Computed tomography (CT) is a non-invasive imaging technique that uses computers to analyze several cross-sectional X-rays to reveal minute details about structures in the body.
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...

Pharmacokinetics in Pediatric Patients: Drug Metabolism

108
In pediatric care, understanding the nuances of hepatic drug metabolism is crucial, as it significantly differs from that of adults. This divergence is primarily due to the developmental stage of drug-metabolizing enzymes, which affects how medications are processed in the body. In neonates, for instance, the activity of Phase I enzymes—critical for the initial breakdown of drugs—is markedly reduced, functioning at just 20–40% of the levels seen in adults. This reduction poses...

Imaging Studies for Cardiovascular System III: X-Ray

392
The most common cardiovascular diagnostic test is an X-ray. It produces images of the heart, blood vessels, and adjacent structures.
Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...

Imaging Studies I: CT and MRI

650
Introduction: MRI and CT scans are crucial advancements in medical imaging techniques, playing a vital role in diagnosing conditions related to the gastrointestinal (GI) system. Each scan serves distinct purposes, targets specific areas, and requires unique nursing duties.
Description of the Procedures
Computed Tomography (CT) scan:
Computed Tomography (CT) scans use X-ray technology to generate detailed images of bones, organs, and tissues. During the scan, the patient lies on a moving table...

Pharmacokinetics in Pediatric Patients: Drug Distribution

168
Drug distribution in the pediatric population exhibits unique challenges and considerations due to the physiological differences between children, particularly neonates and infants, and adults. A crucial aspect of pediatric pharmacology is understanding how these differences impact the pharmacokinetics of various drugs, necessitating age-specific dosing strategies to ensure efficacy and safety.Neonates and infants have a higher total body water content, ~75%–90% of their body weight,...

Area of Science:

  • Pediatric cardiology
  • Medical imaging trends
  • Health services research

Background:

  • Limited data exists on pediatric cardiac imaging trends, contrasting with adult imaging growth.
  • This study addresses the paucity of information on noninvasive cardiac imaging utilization in children.

Purpose of the Study:

  • To analyze temporal trends in pediatric noninvasive cardiac imaging use.
  • To compare these trends with noncardiac imaging utilization.
  • To identify factors influencing pediatric imaging trends.

Main Methods:

  • Utilized Pediatric Health Information Service database for inpatient data (2004-2017).
  • Assessed trends in ultrasound, MRI, and CT for cardiac and noncardiac imaging.
  • Employed linear mixed-effects models adjusted for case-mix, comorbidities, and hospital factors.

Main Results:

  • Pediatric inpatient ultrasound and MRI utilization (cardiac and noncardiac) increased from 2004-2017.
  • Noncardiac CT rates decreased, while cardiac CT use rose significantly after 2014.
  • Case-mix index, cardiac surgical volume, and payer source impacted imaging trend drivers.

Conclusions:

  • Cardiac and noncardiac ultrasound and MRI utilization is rising in pediatric inpatients.
  • Cardiac CT use has increased post-2014, with specific influencing factors identified.
  • This research provides a basis for studying imaging resource use and outcomes in pediatric populations.
