Does Measurement of Preoperative Anxiety Have Added Value for Predicting Postoperative Nausea and Vomiting?
Key result
Adding preoperative anxiety measurement to established predictors did not increase the predictive value for postoperative nausea and vomiting beyond the base model's AUC of 0.72 (95% CI, 0.70-0.74).
Why the study?
Does measurement of preoperative anxiety improve the prediction of postoperative nausea and vomiting in surgical inpatients?
Population
1389 surgical inpatients undergoing various procedures
Comparison
Measurement of preoperative anxiety using the… vs Established predictors of PONV alone
Design
Cohort
Follow-up

Implication
Preoperative anxiety measurement adds no value to PONV prediction; leaves open whether anxiety-targeted interventions reduce incidence.

P
Population
1389 surgical inpatients undergoing various procedures
I
Intervention
Measurement of preoperative anxiety using the Spielberger State-Trait Anxiety Inventory and the Amsterdam Preoperative Anxiety and Information Scale added to established predictors
C
Comparator
Established predictors of PONV alone (sex, age, smoking, history of PONV or motion sickness, surgery type, and anesthetic technique)
O
Outcome
Occurrence of postoperative nausea and vomiting (PONV) in the first 24 h after surgerypatient reported
Main Result
Effect estimate: AUC 0.72 (95% CI 0.70-0.74)
Routine preoperative measurement of anxiety does not add predictive value for postoperative nausea and vomiting when established predictors are already considered.
Cite This Study
Bosch et al. (2005) conducted an observational in Postoperative nausea and vomiting (PONV) (n=1,389). Preoperative anxiety measurement vs. Established predictors of PONV was evaluated on Occurrence of PONV in the first 24 h after surgery (AUC 0.72, 95% CI 0.70-0.74). Adding preoperative anxiety measurement to established predictors did not increase the predictive value for postoperative nausea and vomiting beyond the base model's AUC of 0.72 (95% CI, 0.70-0.74).
