Fundamental Attribution Error01:14

Fundamental Attribution Error

13.8K
According to some social psychologists, people tend to overemphasize internal factors as explanations—or attributions—for the behavior of other people. They tend to assume that the behavior of another person is a trait of that person, and to underestimate the power of the situation on the behavior of others. They tend to fail to recognize when the behavior of another is due to situational variables, and thus to the person’s state. This erroneous assumption is...

Systematic Error: Methodological and Sampling Errors

11.0K
In the case of systematic errors, the sources can be identified, and the errors can be subsequently minimized by addressing these sources. According to the source, systematic errors can be divided into sampling, instrumental, methodological, and personal errors.
Sampling errors originate from improper sampling methods or the wrong sample population. These errors can be minimized by refining the sampling strategy. Defective instruments or faulty calibrations are the sources of instrumental...

Transcription Factors02:16

Transcription Factors

82.8K
Tissue-specific transcription factors contribute to diverse cellular functions in mammals. For example, the gene for beta globin, a major component of hemoglobin, is present in all cells of the body. However, it is only expressed in red blood cells because the transcription factors that can bind to the promoter sequences of the beta globin gene are only expressed in these cells. Tissue-specific transcription factors also ensure that mutations in these factors may impair only the function of...

Random Error01:04

Random Error

9.8K
Random or indeterminate errors originate from various uncontrollable variables, such as variations in environmental conditions, instrument imperfections, or the inherent variability of the phenomena being measured. Usually, these errors cannot be predicted, estimated, or characterized because their direction and magnitude often vary in magnitude and direction even during consecutive measurements. As a result, they are difficult to eliminate. However, the aggregate effect of these errors can be...

Margin of Error01:27

Margin of Error

7.6K
The margin of error is also called the maximum error of an estimate. The margin of error is the maximum possible or expected difference between the observed sample parameter value and the actual population parameter value. For proportion, it is the maximum difference between the value of sample proportion obtained from the data and the true value of population proportion. As the true value of the population parameter is not known, the margin of error is calculated using the sample statistic.

Radiological Investigation I: X-ray and CT

1.2K
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...

Area of Science:

  • Radiology
  • Patient Safety
  • Health Informatics

Background:

  • Diagnostic errors in radiologic imaging pose a significant patient safety concern.
  • Understanding the sources and nature of these errors is crucial for improvement.

Purpose of the Study:

  • To assess various information sources for their ability to identify errors in radiologic diagnostic imaging.
  • To quantify the incidence of potential safety events from each source.
  • To analyze the diagnostic process steps and socio-technical factors involved.

Main Methods:

  • A retrospective study evaluated five information sources: electronic safety reporting system (ESRS), alert notification for critical result (ANCR) system, PACS-based quality assurance (QA) tool, imaging peer-review system, and imaging CPOE and scheduling system.
  • Data were collected and analyzed to quantify potential safety events.
  • Events were classified by diagnostic process steps and socio-technical factors using the SEIPS framework.

Main Results:

  • Potential safety events varied widely across sources, ranging from 0.5% to 62.1%.
  • All evaluated sources contributed to understanding errors in different diagnostic imaging steps.
  • Key socio-technical factors identified were Person, Tasks, and Tools and Technology.

Conclusions:

  • Multiple information sources offer distinct insights into diagnostic process errors in radiologic imaging.
  • These sources are valuable for understanding workflow errors and socio-technical contributors to patient safety.
