Insights

An observation unit (OU) in the emergency department significantly reduced computed tomography (CT) scans for pediatric patients with minor blunt head trauma. This initiative lowered CT use by 30%, avoiding unnecessary radiation exposure.

Area of Science:

  • Emergency Medicine
  • Pediatric Radiology
  • Health Services Research

Background:

  • Minor blunt head trauma in children often leads to computed tomography (CT) scans.
  • Overutilization of CT scans in pediatric patients raises concerns regarding radiation exposure and healthcare costs.

Purpose of the Study:

  • To assess the impact of an emergency department observation unit (OU) on reducing unnecessary CT scans for pediatric patients with minor blunt head trauma.
  • To evaluate the effectiveness of an OU in optimizing diagnostic imaging practices for pediatric head injuries.

Main Methods:

  • A retrospective before-and-after study design was employed.
  • Pediatric patients (≤18 years) with minor blunt head trauma and Glasgow Coma Scale scores of 14-15 were analyzed.
  • Head CT utilization rates were compared before and after the implementation of the OU.

Main Results:

  • A total of 4706 pediatric patients were included in the analysis.
  • Head CT use decreased from 5.7% before OU institution to 4.0% after (P = 0.01).
  • The relative risk reduction in CT use was 0.70, indicating a 30% decrease.

Conclusions:

  • The establishment of an observation unit in the emergency department effectively reduced the rate of head CT scans for pediatric minor head injuries.
  • The OU serves as a valuable strategy for avoiding unnecessary CT imaging in this patient population, mitigating radiation risks.

Minor Losses in Pipes

In pipe systems, minor losses refer to energy losses arising from components such as valves, bends, fittings, expansions, and other features that disrupt the steady flow of fluid. These disturbances cause energy dissipation through turbulence and resistance, which engineers quantify to manage system efficiency effectively.
Valves play a significant role in generating minor losses by obstructing or redirecting the fluid flow. When a valve is closed or partially closed, it restricts the flow...

Measurement: Standard Units03:38

Measurement: Standard Units

Every measurement provides three kinds of information: the size or magnitude of the measurement (a number), a standard of comparison for the measurement (a unit), and an indication of the uncertainty of the measurement. While the number and unit are explicitly represented when a quantity is written, the uncertainty is an aspect of the errors in the measurement results.

Measurement: Derived Units

The International System of Units or SI system, by international agreement, has fixed measurement units for seven fundamental properties: length, mass, time, temperature, electric current, amount of substance, and luminosity. These are called the SI base units.

Naturalistic Observations

If you want to understand how behavior occurs, one of the best ways to gain information is to simply observe the behavior in its natural context. However, people might change their behavior in unexpected ways if they know they are being observed. How do researchers obtain accurate information when people tend to hide their natural behavior? As an example, imagine that your professor asks everyone in your class to raise their hand if they always wash their hands after using the restroom. Chances...

Muscles that Move the Head01:19

Muscles that Move the Head

The muscles that move the head are a dynamic and complex group of structures that work together to facilitate a wide range of head movements, including rotation, flexion, extension, and lateral bending.
The bilateral sternocleidomastoid, or SCM, and the suprahyoid and infrahyoid muscles are significant head flexors. The SCM muscles originate at the sternum and clavicle and attach to the mastoid process of the temporal bone. The SCM contracts bilaterally to bend the head forward, whereas...

Units of Measurement

Mechanical engineering is one of the oldest branches of engineering. It deals with designing, analyzing, and manufacturing machines and mechanical systems. To ensure precise and accurate calculations, units of measurement are used. They provide a standard system for expressing and comparing physical quantities.
There are various well-known historical measurement systems, such as the Babylonian system, the Roman system, the Egyptian system, the Olympian system, the British system, and the Indus...
