Summary
A new questionnaire, the Evaluation du Vecu de l'Anesthesie Generale (EVAN-G), was developed and validated to measure patient satisfaction with general anesthesia. This reliable tool captures patient perceptions during the perioperative period.
Area of Science:
- Anesthesiology
- Patient-Reported Outcomes
- Healthcare Quality Measurement
Background:
- Patient satisfaction is a critical healthcare outcome measure.
- Existing anesthesia-specific questionnaires have limited scope and application.
- A validated tool is needed to assess satisfaction with general anesthesia.
Purpose of the Study:
- To develop and validate the Evaluation du Vecu de l'Anesthesie Generale (EVAN-G) questionnaire.
- To assess patient satisfaction with the perioperative period surrounding general anesthesia.
- To provide a reliable and valid tool for anesthesia practice.
Main Methods:
- Item generation and psychometric validation phases were conducted.
- A patient sample matched to the French general anesthesia population was used.
- Factor analyses, validity, reliability (Cronbach alpha), and test-retest assessments were performed.
Main Results:
- The EVAN-G questionnaire has 26 items with six specific scores and one global index.
- Convergent validity was supported by correlations with other measures.
- Reliability and reproducibility were demonstrated; older patients reported higher satisfaction.
Conclusions:
- The EVAN-G questionnaire effectively captures patients' perceptions of general anesthesia.
- This novel tool offers a valid and reliable method for assessing perioperative satisfaction.
- The EVAN-G can be utilized in clinical anesthesia practice to improve patient care.
