Effect of the COVID-19 pandemic on presentation and severity of traumatic injury due to physical child abuse across US children's hospitals.

BACKGROUND: Physical child abuse affects 9 in every 1,000 children in the United States and associated traumatic injuries are often identified by the healthcare system. The COVID-19 pandemic has intensified risk factors for physical child abuse and increased avoidance of the healthcare system. This study examined the effect of the COVID-19 pandemic on presentation and severity of physical child abuse. METHODS: A retrospective, cross-sectional study utilizing the Pediatric Health Information System was performed. An interrupted time series analysis estimated the effect of the COVID-19 pandemic on the number of children <15 years old presenting with physical child abuse to children's hospitals from March 1st to June 30th of 2020 by comparing to those presenting during the same period for years 2016-2019. Hierarchical regression models estimated the effect of the pandemic on likelihood of operative intervention, ICU admission, traumatic brain injury, and mortality. RESULTS: Over the study period, 20,346 physical child abuse encounters were reported by 47 children's hospitals. An interrupted times series model predicted a significant decline in cases due to the effect of the COVID-19 pandemic, representing a deficit of 2,645 cases (p = 0.001). Children presenting during the pandemic had increased odds of requiring ICU admission (p = 0.03) and having a traumatic brain injury in those under 5 years of age (p=<0.001). CONCLUSIONS: The number of children with physical child abuse presenting to children's hospitals significantly declined during the COVID-19 pandemic, but those that did were more likely to be severe. The pandemic may be a risk factor for worse outcomes associated with physical child abuse.

Effect of consumer-grade wearable device data on clinician decision making during post-discharge telephone calls after pediatric surgery.

BACKGROUND: During post-discharge telephone calls after pediatric surgery, clinicians must rely on parents/caregivers' assessment of symptoms, which can be inaccurate and often lead to unnecessary emergency department (ED) visits. Physiology (heart rate and physical activity) data from consumer-grade wearables, e.g., Fitbit™, may inform clinical decision making, yet there has been little study of clinician interpretation of this data. This study assessed whether wearable data availability, during simulated telephone calls about postoperative, post-discharge pediatric patients, affects clinician decision making. METHODS: Three simulated telephone call scenarios were presented to a diverse group of pediatric surgery clinicians. The scenarios were based on actual postoperative patients (scenarios 1 and 3 have worrisome symptoms and scenario 2 has non-worrisome symptoms) who had worn a Fitbit™ postoperatively. Each scenario was presented to clinicians (1) without any wearable data; (2) with "concerning" wearable data; and (3) with "reassuring" wearable data. Clinicians rated their likelihood, on a scale of 1-10, of recommending an emergency department (ED) visit for the three instances of each scenario, 10 being definitely ED. RESULTS: Twenty-four (24) clinicians participated in the study. When presented with "reassuring" wearable data, clinicians' likelihood of recommending an ED visit decreased from a median score of 6 to 1 (p < 0.001) for scenario 1 and from 9 to 3 (p < 0.001) for scenario 3. When presented with "concerning" wearable data, the median likelihood of recommending an ED visit increased from 1 to 6 (p = 0.003) for scenario 2. CONCLUSION: This study showed that wearable data affect clinicians' decision making and may be useful in triaging postoperative, post-discharge pediatric patients. LEVEL OF EVIDENCE: V.

Baseline preoperative physical activity for surgical patients varies from healthy population controls.

BACKGROUND: Preoperative physical activity (PA) is an important reference point to evaluate recovery, yet is not attainable for emergent surgical admissions. We investigated the validity of PA of healthy children recruited from within the same community as surgical patients and a nationally representative sample as alternative baseline PA for pediatric surgical patients. METHODS: Patients undergoing an elective operation were matched to community-recruited healthy controls (CRHC) on sex, age, and weight, and their PA was assessed using an Actigraph accelerometer. National Health and Nutrition Examination Survey (NHANES) Actigraph PA data were used as a nationally representative match for baseline PA. Surgical patients wore the accelerometer for 2 days preoperatively, CRHC for 2 days, and NHANES participants for 7 days. PA was categorized as light (LPA) or moderate vigorous (MVPA). Means were compared between the 3 groups. RESULTS: Thirty patients were matched with 80 CRHC and 3147 NHANES participants. LPA was similar between surgical patients and CRHC. However, CRHC averaged 19 min/day more MVPA than surgery patients (p = 0.04), and both groups averaged 58 min and 67 min/day higher MVPA than the matched NHANES sample, respectively (p < 0.01). CONCLUSIONS: CRHC LPA was similar to preoperative LPA in surgical patients and may be an alternative. LEVEL OF EVIDENCE: Level II.

Using accelerometers to characterize recovery after surgery in children.

BACKGROUND: Assessment of recovery after surgery in children remains highly subjective. However, advances in wearable technology present an opportunity for clinicians to have an objective assessment of postoperative recovery. The aims of this pilot study are to: (1) evaluate acceptability of accelerometer use in pediatric surgical patients, (2) use accelerometer data to characterize the recovery trajectory of physical activity, and (3) determine if postoperative adverse events are associated with a decrease in physical activity. STUDY DESIGN: Children aged 3-18-years-old undergoing elective inpatient and outpatient surgical procedures were invited to participate. Physical activity was measured using an Actigraph GT3X wristworn accelerometer for ≥2days preoperatively and 5-14days postoperatively. Time spent performing light (LPA) and moderate-to-vigorous physical activity (MVPA) was expressed in minutes/day. Physical activity for each postoperative day was calculated as a percentage of preoperative activity, and recovery trajectories were produced. Adverse events were reported and mapped against recovery trajectories. RESULTS: Of 60 patients enrolled, 25 (10 inpatients, 15 outpatients) completed the study procedures and were included in the analysis. For outpatient procedures, LPA recovered to preoperative level on postoperative day (POD) 7 and MVPA peaked at 90% on POD 8. For inpatient procedures, LPA peaked at 70% on POD 11, and MVPA peaked at 53% on POD 10. Adverse events in 2 patients were associated with a decline in activity. CONCLUSIONS: This study demonstrates that objective monitoring of postoperative physical activity using accelerometers is feasible in the pediatric surgical population. Recovery trajectories for inpatient and outpatient procedures differ. Accelerometer technology presents clinicians with a new potential tool for assessing and managing surgical recovery, and for determining if children are not recovering as expected.
