Utility of the Pediatric Bleeding Questionnaire in Predicting Posttonsillectomy Bleeding.

OBJECTIVE

Posttonsillectomy bleeding is a dreadful complication that may be life-threatening. Preoperative coagulation tests have not been shown to be effective in predicting this complication. The Pediatric Bleeding Questionnaire (PBQ) is a validated and sensitive tool in diagnosing children with abnormal hemostatic functions, and the objective of our study was to assess its utility as a preoperative screening tool for predicting posttonsillectomy bleeding.

STUDY

DESIGN

Prospective single-blinded cohort study.

SETTING

Tertiary care hospital system.

METHODS

All children scheduled for tonsil surgery between 2017 and 2019 in the Galilee Medical Center were included. The PBQ was completed by the caregivers prior to surgery, and all children underwent coagulation tests. Each PBQ item is scored on a scale of -1 to 4, and the total score per candidate is based on summation of all items.

RESULTS

An overall 272 patients were included in the study with a mean age of 5.2 years; 57.7% were boys. The main finding was that in a multivariable model adjusted to age, a PBQ score of 2 is correlated with increased postoperative bleeding risk (odds ratio, 10.018 [95% CI, 1.20-82.74]; P = .046). The results of the PBQ demonstrated better predictive ability when compared with abnormal coagulation test results (odds ratio, 1.76 [95% CI, 0.63-4.80]; P = .279). Sex was not found to be significant (odds ratio, 1.45 [95% CI, 0.70-3.18]; P = .343).

CONCLUSIONS

This study demonstrated that a PBQ score ≥2 has a higher yield for detecting children at risk for posttonsil surgery bleeding as compared with coagulation studies.
