Evaluating Outcomes of Nonaccidental Trauma in Military Children.

BACKGROUND: Nonaccidental trauma (NAT), or child abuse, is a leading cause of childhood injury and death in the US. Studies demonstrate that military-affiliated individuals are at greater risk of mental health complication and family violence, including child maltreatment. There is limited information about the outcomes of military children who experience NAT. This study compares the outcomes between military-dependent and civilian children diagnosed with NAT. STUDY DESIGN: A single-institution, retrospective review of children admitted with confirmed NAT at a Level I trauma center was performed. Data were collected from the institutional trauma registry and the Child Abuse Team's database. Military affiliation was identified using insurance status and parental or caregiver self-reported active-duty status. Demographic and clinical data including hospital length of stay (LOS), morbidity, specialty consult, and mortality were compared. RESULTS: Among 535 patients, 11.8% (n = 63) were military-affiliated. The median age of military-associated patients, 3 months (interquartile range [IQR] 1 to 7), was significantly younger than civilian patients, 7 months (IQR 3 to 18, p < 0.001). Military-affilif:ated patients had a longer LOS of 4 days (IQR 2 to 11) vs 2 days (IQR 1 to 7, p = 0.041), increased morbidity or complication (3 vs 2 counts, p = 0.002), and a higher mortality rate (10% vs 4%, p = 0.048). No significant difference was observed in the number of consults or injuries, trauma activation, or need for surgery. CONCLUSIONS: Military-affiliated children diagnosed with NAT experience more adverse outcomes than civilian patients. Increased LOS, morbidity or complication, and mortality suggest military-affiliated patients experience more life-threatening NAT at a younger age. Larger studies are required to further examine this population and better support at-risk families.

Application of a Machine Learning Algorithm in Prediction of Abusive Head Trauma in Children.

PURPOSE: We explored the application of a machine learning algorithm for the timely detection of potential abusive head trauma (AHT) using the first free-text note of an encounter and demographic information. METHODS: First free-text physician notes and demographic information were collected for children under 5 years of age at a Level 1 Trauma Center. The control group, which included patients with head/neck injury, was compared to those with AHT diagnosed by the Child Protective Team. Differential scores accounted for words overrepresented in AHT patient vs. control notes. Sentiment scores were reflective of note positivity/negativity and subjectivity scores accounted for note subjectivity/objectivity. The composite scores reflected the patient's differential score modified by the subjectivity score. Composite, sentiment, and subjectivity scores combined with demographic information trained a Random Forest (RF) machine learning algorithm to predict AHT. RESULTS: Final composite scores with demographic information were highly associated with AHT in a test dataset. The control group included 587 patients and the test group included 193 patients. Combining composite scores with demographic information into the RF model improved AHT classification area under the curve (AUC) from 0.68 to 0.78, with an overall accuracy of 84%. Feature importance analysis of our RF model revealed that composite score, sentiment, age, and subjectivity were the most impactful predictors of AHT. The sentiment was not significantly different between control and AHT notes (p = 0.87), while subjectivity trended higher for AHT notes (p = 0.081). CONCLUSION: We conclude that a machine learning algorithm can recognize patterns within free-text notes and demographic information that aid in AHT detection in children. LEVEL OF EVIDENCE: III.

Standardized perioperative care reduces colorectal surgical site infection in children: A Western Pediatric Surgery Research Consortium multicenter analysis.

PURPOSE: Surgical site infection (SSI) remains a significant source of patient morbidity and resource utilization in children undergoing colorectal surgery. We examined the utility of a protocolized perioperative care bundle in reducing SSI in pediatric patients undergoing colorectal surgery. METHODS: We conducted a prospective cohort study of patients ≤18 years of age undergoing colorectal surgery at ten United States children's hospitals. Using a perioperative care protocol comprising eight elements, or "colon bundle", we divided patients into low (1-4 elements) or high (5-8 elements) compliance cohorts. Procedures involving colorectal repair or anastomosis with abdominal closure were included. Demographics and clinical outcomes were compared between low and high compliance cohorts. Compliance was compared with a retrospective cohort. The primary outcome was superficial SSI incidence at 30 days. RESULTS: Three hundred and thirty-six patients were included in our analysis: 138 from the low compliance cohort and 198 from the high compliance cohort. Age and gender were similar between groups. Preoperative diagnosis was similar except for more patients in the high compliance cohort having inflammatory bowel disease (18.2% versus 5.8%, p<0.01). The most common procedure performed was small bowel to colorectal anastomosis. Wound classification and procedure acuity were similar between groups. Superficial SSI at 30 days occurred less frequently among the high compliance compared to the low compliance cohort (4% versus 9.7%, p = 0.036). Median postoperative length of stay and 30-day rates of readmission, reoperation, intra-abdominal abscess and anastomotic leak requiring operation were not significantly different between groups. None of the individual colon bundle elements were independently protective against superficial SSI. CONCLUSION: Standardization of perioperative care is associated with a reduction in superficial SSI in pediatric colorectal surgery. Expansion of standardized protocols for children undergoing colorectal surgery may improve outcomes and decrease perioperative morbidity.
