Insights

Electroencephalography (EEG) is underutilized in intracerebral hemorrhage (ICH) patients, with less than half of eligible individuals receiving the test. Factors beyond consensus guidelines influence EEG prescription, highlighting a need for further research.

Area of Science:

  • Neurocritical care
  • Clinical neurophysiology
  • Neurology

Background:

  • Intracerebral hemorrhage (ICH) is a critical neurological condition requiring intensive monitoring.
  • Electroencephalography (EEG) is a key diagnostic tool in neurocritical care, but its utilization in ICH patients is not well-defined.

Purpose of the Study:

  • To investigate clinical factors influencing EEG prescription in critically-ill ICH patients.
  • To compare current EEG prescription patterns with established consensus recommendations.

Main Methods:

  • Retrospective analysis of 330 ICH patients admitted to a neurointensive care unit.
  • Comparison of EEG prescription patterns against EEG consensus guidelines.
  • Logistic regression modeling to identify clinical variables associated with EEG ordering.

Main Results:

  • Only 41% of eligible ICH patients underwent EEG according to consensus guidelines.
  • EEG prescription was associated with guideline adherence, lower Glasgow Coma Scale (GCS) scores, and clinical seizures.
  • EEG findings influenced clinical decision-making in 60% of patients who underwent the procedure.

Conclusions:

  • EEG appears underused in ICH patients, with prescription influenced by factors beyond current consensus recommendations.
  • Further validation of these findings and their impact on patient outcomes is necessary.

Patient-centered Care01:13

Patient-centered Care

Patient-centered care involves delivering care beyond inpatient hospitalization. Reflective practice can enhance a patient-centered approach. Reflective practice is a process of reasoning that considers all aspects of the present situation, including practicalities, learning from personal practice, and consideration of patient needs. Patients appreciate care decisions made while considering their input. Involving the patient in their care provides the patient with a sense of contribution rather...

Prescription, Nonprescription and Orphan Drugs

Prescription drugs require a prescription from a medical practitioner and can only be obtained from a pharmacy. They have many applications, including treating pain, anxiety, and hypertension.
The misuse and addiction to prescription drugs is a growing problem that can affect people of all age groups, specifically teenagers. This can happen when prescription medications are used in ways not intended by the prescriber, such as taking someone else's prescription or using medication for...

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.

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...

International System of Units

The International System of Units, known as the SI system, is a universally accepted measurement system recognized and used worldwide. The SI system is based on a set of three base units considered absolute, and their values do not change with location. These base units are meters, kilograms, and seconds.
Prefixes are used to define both larger and smaller quantities in the SI system. For example, milli, micro, and nano define smaller quantities, while kilo, mega, and giga are used to define...
