Insights
A new pediatric comorbidity index effectively predicts postoperative complications in children, outperforming existing tools for both inpatient and ambulatory surgery. This tool aids in risk assessment and perioperative planning.
Area of Science:
- Pediatric Surgery
- Health Services Research
- Medical Informatics
Background:
- Accurate surgical risk assessment in children is crucial for patient counseling and research.
- Existing mortality-focused comorbidity indices show limited success in pediatric risk adjustment.
Purpose of the Study:
- To develop and validate a novel, comorbidity-driven surgical risk index for predicting 30-day postoperative complications in pediatric patients.
- To compare the performance of the new index against established comorbidity indices.
Main Methods:
- Retrospective cohort study using MarketScan® Research databases (2014-2015).
- Development of a novel index using logistic regression for ambulatory and inpatient pediatric surgery cohorts.
- Performance comparison using area under the receiver operating characteristics curves (AUC) against Charlson Comorbidity Index (CCI), Van Walraven Index (VWI), and Rhee Score (RS).
Main Results:
- The novel index demonstrated superior discrimination of postoperative complications in inpatients (AUC 0.76) compared to CCI (0.56), VWI (0.60), and RS (0.69).
- For ambulatory surgery, the novel index also outperformed existing indices (AUC 0.68), although overall discriminatory ability was moderate.
- A total of 190,629 ambulatory and 22,633 inpatient pediatric surgical cases were analyzed.
Conclusions:
- The developed pediatric comorbidity index offers improved prediction of postoperative complications over existing measures in both inpatient and ambulatory settings.
- This novel index is valuable for research and has potential clinical applications in identifying high-risk pediatric surgical patients and optimizing perioperative care.
Introduction/Background:
Comorbidity-driven surgical risk assessment is essential for informed patient counseling, risk-stratification, and outcomes-based health-services research. Existing mortality-focused comorbidity indices have had mixed success at risk-adjustment in children.
Objective:
To develop a new comorbidity-driven multispecialty surgical risk index predicting 30-day postoperative complications in children.
Study Design:
This retrospective cohort study investigated children undergoing surgical procedures across seven specialties in 2014-2015 using the MarketScan® Research databases. The risk index was derived separately for ambulatory and inpatient surgery patients using logistic regression with backward selection. The performance of the novel index in discriminating postoperative complications vis-à-vis three existing comorbidity indices was compared using bootstrapping and area under the receiver operating characteristics curves (AUC).
Results:
We identified 190,629 ambulatory and 22,633 inpatient patients. The novel index had the best performance for discriminating postoperative complications for inpatients (AUC 0.76, 95% confidence interval [CI] 0.75-0.77) relative to the Charlson Comorbidity Index (CCI, 0.56, 95% CI 0.56-0.57), Van Walraven Index (VWI, 0.60, 95% CI 0.60-0.61), and Rhee Score (RS, 0.69, 95% CI 0.68-0.70). In the ambulatory cohort, the novel index outperformed all three existing indices, though none demonstrated excellent discriminatory ability for complications (novel score 0.68, 95% CI 0.67-0.68; CCI 0.53, 95% CI 0.52-0.53; VWI 0.53, 95% CI 0.52-0.53; RS 0.50, 95% CI 0.49-0.50).
Discussion:
In both inpatient and ambulatory pediatric settings, our novel comorbidity index demonstrated better performance at predicting postoperative complications than three widely used alternatives. This index will be useful for research and may be adaptable to clinical settings to identify high-risk patients and facilitate perioperative planning.
Conclusion:
We developed a novel pediatric comorbidity index with better performance at predicting postoperative complications than three widely used alternatives.
