Summary
A new trainer assessment questionnaire, the OxTrAQ, was developed and validated. It demonstrates high reliability for assessing surgical trainers, improving the quality of surgical education.
Area of Science:
- Medical Education
- Surgical Training Assessment
- Psychometrics
Background:
- Surgical trainee assessment is established, but trainer assessment is lacking.
- A systematic review identified 12 key attributes for surgical trainers.
Purpose of the Study:
- Develop the Oxford Trainer Assessment Questionnaire (OxTrAQ).
- Explore the questionnaire's domains.
- Test the reliability and validity of the OxTrAQ.
Main Methods:
- Piloted the OxTrAQ at two surgical training centers across two sub-specialties.
- Trainees assessed trainers under clinical supervision.
- Statistical analyses included Cronbach's alpha, factor analysis, and intraclass correlation coefficients (ICCs).
Main Results:
- The 12-item OxTrAQ showed high internal consistency (Cronbach's alpha = 0.958).
- Factor analysis identified two domains: general (9 items) and independence (3 items).
- Excellent inter-observer and intra-observer reliability were demonstrated (ICCs > 0.8). Construct validity was also confirmed.
Conclusions:
- The OxTrAQ is a reliable and valid tool for assessing surgical trainers.
- This questionnaire can enhance the quality of surgical education by providing structured feedback to trainers.

The two sources for collecting information are primary and secondary. After gathering information, interpretation and validation help to complete the data. The purpose of assessment is to establish data with the initial information, to interpret data about the patient's perceived needs and health problems, and to respond to these problems identified.
The nurse collects all aspects of the patient's health in the initial assessment, establishing priorities for ongoing focused assessments...

Evaluating the rectum and anus plays a crucial role in conducting a thorough physical examination of the gastrointestinal system. Although it may be uncomfortable and often embarrassing for the patient, it holds immense diagnostic value, particularly in detecting gastrointestinal diseases and abnormalities. This guide will explain how to perform this assessment using inspection and palpation methods.

01:23Assessment of the Abdomen III: Palpation
3.9K
Palpation is a crucial tactile examination method for assessing abdominal organs and detecting conditions like tenderness, distention, masses, or fluid. It involves both light and deep palpation techniques, each serving specific diagnostic purposes. Light palpation helps identify tenderness and other surface-level indicators, while deep palpation locates and assess abdominal masses and organ boundaries. A skilled professional can gather valuable insights through palpation, including evaluating...
