Polygenic Score for the Prediction of Postoperative Nausea and Vomiting: A Retrospective Derivation and Validation Cohort Study

AnesthesiologyPublished Retrospective derivation and validation cohort study

Authors' conclusion

Standardized polygenic risk was associated with PONV in all three of the study's models, but the genetic influence was smaller than exerted by clinical risk factors.

Study context

Population
Surgeries under GA with integrated genetic and perioperative data at Michigan Medicine and Vanderbilt University Medical Center
Participants
64,523 participants
Comparison
Polygenic score added to clinical risk models for postoperative nausea and vomiting (PONV) prediction
Outcome
PONV (nausea or emesis documented in the PACU)
Methodological detailsgenome-wide association study, meta-analysis of cohorts, multicentre
  • Genome-wide association study
  • Meta-analysis of cohorts
  • Multicentre
