Summary
The Indicator of Sedation Need (IOSN) tool shows promise in identifying Chinese dental patients who may benefit from sedation. Moderate agreement was found between IOSN recommendations and ideal anesthesia plans.
Area of Science:
- Dental Medicine
- Anesthesiology
- Psychology
Background:
- Dental anxiety and sedation needs assessment is crucial for patient care.
- The Indicator of Sedation Need (IOSN) tool requires evaluation in diverse populations.
- This study focuses on Chinese dental patients undergoing common procedures.
Purpose of the Study:
- To evaluate the effectiveness and applicability of the IOSN tool.
- To assess dental anxiety and sedation needs in Chinese patients.
- To determine the tool's agreement with established anesthesia plans.
Main Methods:
- A cross-sectional study of 153 adult patients at Peking Union Medical College Hospital.
- Participants completed a Chinese questionnaire including the IOSN scale and anesthesia evaluation.
- Data analyzed using descriptive statistics, two-way ANOVA, and Kappa analysis.
Main Results:
- Significant differences in IOSN scores were found across anesthesia types, gender, and treatment type (P < 0.05).
- 94.8% of patients rated their anesthesia as appropriate.
- Moderate agreement (κ = 0.4615) was observed between IOSN recommendations and the adjusted ideal anesthesia plan.
Conclusions:
- The IOSN tool demonstrates preliminary potential for assessing sedation needs in Chinese dental patients.
- The tool effectively identifies patients who may benefit from sedation.
- Further validation studies are recommended to confirm findings.
