A questionnaire for measuring patient satisfaction to general anesthesia

Area of Science:

• Anesthesiology
• Patient Experience Measurement
• Health Services Research

Background:

• Assessing patient satisfaction with general anesthesia requires a valid and reliable tool.
• No standardized Thai version currently exists for this purpose.
• This study aimed to fill that gap.

Purpose of the Study:

• To develop and validate a reliable Thai questionnaire for measuring patient satisfaction with general anesthesia.
• To ensure the tool covers all essential dimensions of patient satisfaction.
• To provide a culturally relevant instrument for Thai healthcare settings.

Main Methods:

• Literature review and patient interviews to identify satisfaction dimensions.
• Item generation based on customer satisfaction principles.
• Pilot testing, content validity verification, and item analysis (correlation, missing responses).
• Reliability assessment using Cronbach's alpha at two distinct hospitals.

Main Results:

• A ten-item final questionnaire was developed.
• All items demonstrated high correlation ( > 0.5).
• Cronbach's alpha coefficients were 0.8775 (King Chulalongkorn Memorial Hospital) and 0.7571 (Police General Hospital), indicating good reliability.

Conclusions:

• The developed questionnaire is valid and reliable for measuring patient satisfaction with general anesthesia.
• The tool's generalizability was confirmed through testing at a second hospital.
• This instrument provides a much-needed resource for assessing patient satisfaction in Thailand.
