Summary
Emergency radiologists largely agree on prompt contrast-enhanced CT (CECT) for sepsis diagnosis. While most prefer CECT within 1-6 hours, interdisciplinary differences in timing and indications warrant further investigation.
Area of Science:
- Radiology
- Emergency Medicine
- Infectious Diseases
Background:
- Sepsis management relies on timely diagnosis and source identification.
- Contrast-enhanced CT (CECT) plays a crucial role in detecting infectious foci.
- Understanding emergency radiologists' perspectives is key to optimizing CECT protocols.
Purpose of the Study:
- To survey emergency radiologists on their views regarding CECT in sepsis management.
- To compare these views with those of other clinical specialists.
Main Methods:
- A 2023 survey of European Society of Emergency Radiology (ESER) members (n=297) was conducted.
- The survey assessed perspectives on CECT timing and rationale in sepsis.
- Responses were analyzed using descriptive statistics and chi-square tests, compared to prior data.
Main Results:
- 144 emergency radiologists participated, with most favoring CECT within 1-6 hours of sepsis diagnosis.
- A significant portion (35.6%) accepted intervals >12 hours.
- Emergency radiologists were more inclined towards repeat imaging in deteriorating sepsis patients compared to clinicians.
Conclusions:
- Emergency radiologists strongly agree on the importance of prompt CECT for sepsis diagnosis.
- Significant interdisciplinary differences exist regarding CECT timing and indications.
- Further research is needed to address these discrepancies and refine sepsis management protocols.

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...

Often, psychologists develop surveys as a means of gathering data. Surveys are lists of questions to be answered by research participants, and can be delivered as paper-and-pencil questionnaires, administered electronically, or conducted verbally. Generally, the survey itself can be completed in a short time, and the ease of administering a survey makes it easy to collect data from a large number of people.

Surveying is the art and science of mapping the earth's surface. It involves measuring distances, angles in horizontal or vertical directions, and levels to understand the shape and size of land features. Surveying techniques are essential for various tasks, such as identifying the levels of a land area with reference to a specific point, and mapping undulations and water bodies.There are two main types of surveying: plane surveys and geodetic surveys. Plane surveys assume the earth is flat,...

Jeffrey Arnett's concept of emerging adulthood offers a framework to understand the unique developmental stage between adolescence and full-fledged adulthood, generally from ages 18 to 25. This period is marked by extensive exploration and shifts in identity, relationships, and career choices, a process known in psychology as role experimentation. Emerging adulthood reflects the evolving cultural expectations surrounding adulthood and the dynamic process of personal transformation during...

Surveys are essential for marking property boundaries near water bodies. Different types of surveys are defined, each with its own function. Land surveys mark the property boundaries, while route surveys determine the position of properties on nearby highways. Topographic surveys create maps by capturing the three-dimensional features of the land. Hydrographic surveys focus on the shapes of underwater areas and the movement of streams through the properties. Mine surveys determine the relative...

Surveying near highways, rough terrain, or power lines involves significant risks. Working along highways is particularly dangerous and requires the use of warning signs and flagmen. It is safest to avoid working directly on roads and use offsets whenever possible. When highway work is unavoidable, it must follow all safety guidelines. Surveyors should wear bright clothing, such as orange reflective vests, to ensure visibility to motorists, coworkers, and hunters. In construction zones, wearing...
