Radiological Investigation I: X-ray and CT01:30

Radiological Investigation I: X-ray and CT

917
Radiological investigations, including X-rays and computed tomography (CT) scans, are critical for diagnosing and evaluating various medical conditions. These imaging techniques provide valuable insights into the body's internal structures, aiding in the detection of abnormalities, assessment of disease progression, and development of treatment strategies. This article delves into two primary radiological investigations, chest X-rays and CT scans, outlining their purpose, procedures, and...

Radiological Investigation III: Pulmonary Angiogram and PET Scan

315
Radiological investigations are paramount in the diagnosis and management of various pulmonary diseases. Two essential investigations are the Pulmonary Angiogram and the Positron Emission Tomography (PET) Scan.
Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...

Imaging Studies for Cardiovascular System III: X-Ray

397
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...

Pneumothorax-II01:27

Pneumothorax-II

715
Pneumothorax is a medical condition defined by the buildup of air in the pleural space between the lungs and the chest wall. This accumulation of air can lead to partial or complete lung collapse, resulting in a range of clinical manifestations. Understanding the clinical presentation and effective management strategies is crucial for healthcare professionals in providing timely and appropriate care to individuals with pneumothorax.

Radiological Investigation II: MRI and Ventilation Perfusion Scan01:30

Radiological Investigation II: MRI and Ventilation Perfusion Scan

405
Description
Magnetic Resonance Imaging (MRI) and Ventilation Perfusion Scans are two radiological investigations that offer detailed diagnostic images of the body, particularly lung structures.
MRI
MRI uses magnetic fields and radiofrequency signals to distinguish between normal and abnormal tissues. This technology provides a more detailed diagnostic image than CT scans, enabling it to characterize pulmonary nodules, stage bronchogenic carcinoma, and evaluate inflammatory activity in...

Assessment of Respiration01:23

Assessment of Respiration

1.7K
The respiratory system's basic structures and primary functions lay the foundation for nurses' comprehensive respiratory assessments. This assessment includes subjective and objective data to gauge the patient's respiratory health.
Subjective Assessment: Nurses interview the patient to gather information directly during the subjective assessment. It includes questions about the individual's medical history, medications, and symptoms, focusing on past respiratory conditions like...

Area of Science:

  • Healthcare Management
  • Radiology
  • Critical Care Medicine

Background:

  • Routine portable chest radiography in adult intensive care units (ICUs) is common but often overutilized.
  • Evidence-based guidelines suggest selective ordering of chest imaging.
  • Cost-effectiveness of imaging practices in ICUs is a significant concern.

Purpose of the Study:

  • To decrease the utilization of routine portable chest radiography in adult ICUs.
  • To demonstrate cost savings associated with reduced imaging using time-driven activity-based costing.
  • To align clinical practice with evidence-based medicine.

Main Methods:

  • A multidisciplinary team mapped the portable chest radiography process and conducted time trials to determine costs.
  • Changes were implemented in resident education, ordering protocols, and workflows to discontinue routine daily chest radiography.
  • Routine imaging was reserved for specific indications like admission or central line placement; complications were tracked as a balancing measure.

Main Results:

  • A 37% decrease in portable chest radiography utilization was observed in adult ICUs within six months.
  • No increase in unplanned extubations or ventilator days was noted.
  • Significant cost savings were realized, as confirmed by time-driven activity-based costing.

Conclusions:

  • Performance improvement initiatives can successfully align clinical practice with evidence-based medicine in ICUs.
  • Decreasing routine chest radiography utilization reduces costs without compromising patient safety or increasing complications.
  • This approach enhances the value of care delivered to ICU patients.
