The evaluation of three comorbidity indices in predicting postoperative complications and readmissions in pediatric urology

The three comorbidity indices evaluated are poor discriminators for postoperative complications, 30-day inpatient readmissions or 30-day ER admissions. A new index is needed for pediatric urology patients.Table Results summary.30-day inpatient readmission30-day ER admissionPostoperative complicationCCSAUC = 0.63 (95% CI 0.61-0.66)AUC = 0.52 (95% CI 0.50-0.54)AUC = 0.62 (95% CI 0.58-0.66)VWIAUC = 0.54 (95% CI 0.52-0.56)AUC = 0.51 (95% CI 0.49-0.53)AUC = 0.61 (95% CI 0.58-0.65)RheeAUC = 0.56 (95% CI 0.53-0.58)AUC = 0.50 (95% CI 0.48-0.52)AUC = 0.67 (95% CI 0.63-0.71)Comparisonp < 0.001*p < 0.4*p < 0.05**The p-value represents the larger p-value between the two comorbidity scores compared with the reference score.* Charlson Comorbidity Score was used as the reference group.** Rhee was used as the reference group.
