Summary
Structured documentation in radiation oncology using defined data elements is scarce. A comprehensive list of radiation therapy (RT)-specific common data elements (CDEs) is needed to improve standardization and data exchange in clinical practice and research.
Area of Science:
- Radiation oncology informatics
- Medical data standardization
- Clinical trial data management
Background:
- Structured medical data documentation is crucial in radiation oncology.
- Defined data elements (CDEs) enhance standardization and data exchange in clinical trials and health records.
- The International Society for Radiation Oncology Informatics initiated a project to analyze literature on CDEs for radiation oncology documentation.
Approach:
- A systematic literature review was conducted on PubMed and Scopus.
- Publications were analyzed for the utilization of specified data elements in radiation therapy documentation.
- Extracted data elements were quantitatively analyzed and classified.
Key Points:
- 452 publications were reviewed, with 46 deemed relevant for structured data documentation.
- Only two publications focused specifically on data elements in radiation oncology.
- Analyzed publications showed heterogeneity in subject, usage, and terminology for defined data elements.
Conclusions:
- Literature on structured data documentation in radiation oncology using CDEs is limited.
- There is a significant need for a comprehensive list of RT-specific CDEs.
- Establishing such a list would promote interoperability and standardization in radiation oncology practice and research.

01:21Cancer Survival Analysis
402
Cancer survival analysis focuses on quantifying and interpreting the time from a key starting point, such as diagnosis or the initiation of treatment, to a specific endpoint, such as remission or death. This analysis provides critical insights into treatment effectiveness and factors that influence patient outcomes, helping to shape clinical decisions and guide prognostic evaluations. A cornerstone of oncology research, survival analysis tackles the challenges of skewed, non-normally...

01:30Radiological Investigation I: X-ray and CT
298
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...

01:13Radiological Investigation III: Pulmonary Angiogram and PET Scan
117
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...

4.3K
Positron emission tomography (PET) is a medical imaging technique involving radiopharmaceuticals — substances that emit short-lived radiation. Although the first PET scanner was introduced in 1961, it took 15 more years before radiopharmaceuticals were combined with the technique and revolutionized its potential.
One of the main requirements of a PET scan is a positron-emitting radioisotope, which is produced in a cyclotron and then attached to a substance used by the part of the body...

01:30Methods of Documentation VII: EMR
868
Electronic Medical Records (EMRs) primarily center around electronically documenting patients' health information within a single healthcare organization or practice. They contain essential clinical data related to a patient's medical history, diagnoses, medications, treatment plans, lab results, and other pertinent information relevant to the specific encounter or episode of care. EMRs are designed to streamline documentation and workflow processes within individual healthcare...

01:12Hazard Ratio
166
The hazard ratio (HR) is a widely used measure in clinical trials to compare the risk of events, such as death or disease recurrence, between two groups over time. It reflects the ratio of hazard rates—the instantaneous risk of the event occurring—between a treatment group and a control group. This measure provides valuable insights into the relative effectiveness of a treatment by assessing how the risk of an event differs between the two groups.
For example, in a clinical trial...
