Interrater reliability of chart-based assessment of functional impairment after pediatric injury using the functional status scale

Aspartate aminotransferase and alanine aminotransferase elevation in suspected physical abuse: Can the threshold to obtain an abdominal computed tomography be raised?

BACKGROUND

Identification of abdominal injury (AI) in children with concern for physical abuse is important, as it can provide important medical and forensic information. Current recommendations are to obtain screening liver function tests (LFTs) in all children with suspected physical abuse and an abdominal computed tomography (CT) when the aspartate aminotransferase (AST) or alanine aminotransferase (ALT) is >80 IU/L. This threshold to obtain an abdominal CT is lower than general trauma guidelines, which use a cutoff of AST >200 IU/L or ALT >125 IU/L.

METHODS

This was a retrospective review of children aged 0 to 60 months at a single pediatric tertiary care center who were evaluated for physical abuse and had AST or ALT >80 IU/L. Subjects were then stratified into two groups: midrange (AST ≤200 IU/L and ALT ≤125 IU/L) and high-range (AST >200 IU/L and/or ALT >125 IU/L) LFTs.

RESULTS

Abdominal CTs were performed in 55% (131 of 237) of subjects, 38% (50 of 131) with midrange LFTs and 62% (81 of 131) with high-range LFTs. Abdominal injury was identified in 19.8% (26 of 131) of subjects. Subjects with AI were older than those without AI (mean [SD] age, 18.7 [12.5] vs. 11.6 [12.2] months; p = 0.009). The highest yield of abdominal CTs positive for AI was in the group with high-range LFTs with signs or symptoms of AI at 52.0% (13 of 25; 95% confidence interval, 31.3-72.2%). The negative predictive value of having midrange LFTs and no signs or symptoms of AI was 100% (95% confidence interval, 97.0-100%).

CONCLUSION

Our data suggest that abdominal CT may not be necessary in children being evaluated for physical abuse who have AST ≤200 IU/L and ALT ≤125 IU/L and do not have signs or symptoms of AI. This could limit the number of abdominal CTs performed.

New Functional Impairment After Hospital Discharge by Traumatic Brain Injury Mechanism in Younger Than 3 Years Old Admitted to the PICU in a Single Center Retrospective Study

OBJECTIVES

Children who suffer traumatic brain injury (TBI) are at high risk of morbidity and mortality. We hypothesized that in patients with TBI, the abusive head trauma (AHT) mechanism vs. accidental TBI (aTBI) would be associated with higher frequency of new functional impairment between baseline and later follow-up.

DESIGN

Retrospective single center cohort study.

SETTING AND PATIENTS

Children younger than 3 years old admitted with TBI to the PICU at a level 1 trauma center between 2014 and 2019.

INTERVENTIONS

None.

MEASUREMENTS AND MAIN RESULTS

Patient characteristics, TBI mechanism, and Functional Status Scale (FSS) scores at baseline, hospital discharge, short-term (median, 10 mo [interquartile range 3-12 mo]), and long-term (median, 4 yr [3-6 yr]) postdischarge were abstracted from the electronic health record. New impairment was defined as an increase in FSS greater than 1 from baseline. Patients who died were assigned the highest score (30). Multivariable logistic regression was performed to determine the association between TBI mechanism with new impairment. Over 6 years, there were 460 TBI children (170 AHT, 290 aTBI), of which 13 with AHT and four with aTBI died. Frequency of new impairment by follow-up interval, in AHT vs. aTBI patients, were as follows: hospital discharge (42/157 [27%] vs. 27/286 [9%]; p < 0.001), short-term (42/153 [27%] vs. 26/259 [10%]; p < 0.001), and long-term (32/114 [28%] vs. 18/178 [10%]; p < 0.001). Sensory, communication, and motor domains were worse in AHT patients at the short- and long-term timepoint. On multivariable analysis, AHT mechanism was associated with greater odds (odds ratio [95% CI]) of poor outcome (death and new impairment) at hospital discharge (4.4 [2.2-8.9]), short-term (2.7 [1.5-4.9]), and long-term timepoints (2.4 [1.2-4.8]; p < 0.05).

CONCLUSIONS

In patients younger than 3 years old admitted to the PICU after TBI, the AHT mechanism-vs. aTBI-is associated with greater odds of poor outcome in the follow-up period through to ~5 years postdischarge. New impairment occurred in multiple domains and only AHT patients further declined in FSS over time.
