Pediatric minor head trauma: do cranial CT scans change the therapeutic approach?

Computed Tomography Overuse in Pediatric Minor Head Trauma: Insights from a Single-Center Experience

BACKGROUND

Minor head trauma is a common reason for emergency department visits in children, but many of these cases are not clinically significant. Despite established criteria for selecting patients who require computed tomography (CT), concerns about overuse of CT persist. This study aimed to determine the frequency of clinically important traumatic brain injury by retrospectively evaluating cranial CT scans in children categorized as very low risk for such injuries based on PECARN prediction rules.

MATERIALS AND METHODS

Cranial CT scans of 941 minor head trauma cases were assessed for the presence, type, and number of calvarial bone fractures. Concomitant bleeding and treatment approaches were also recorded.

RESULTS

Among 881 patients (93.6%), cranial CT scans did not reveal any lesions apart from soft tissue edema. None of the cases had clinically important traumatic brain injury or required neurosurgical intervention.

DISCUSSION AND CONCLUSION

The study demonstrated that 93.6% of cranial CT scans for pediatric minor head trauma were negative, indicating a concerningly high rate of CT overuse. Although prediction rules exist, their application in clinical practice is not always optimal. Given the principle of "first, do no harm," proper patient selection is crucial to avoid unnecessary exposure to ionizing radiation.

Paediatric minor head injury applied to Paediatric Emergency Care Applied Research Network CT recommendations: An audit

Background

Traumatic brain injury (TBI) is a common cause of paediatric morbidity and mortality, with higher TBI rates in low- and middle-income countries. Non-contrast brain CT is the gold standard for diagnosing intracranial injuries; however, it exposes patients to ionising radiation. The Paediatric Emergency Care Applied Research Network (PECARN) clinical decision rule (CDR) aids clinicians in their decision-making processes whilst deciding whether a patient at very low risk of a clinically important TBI (ciTBI) requires a CT scan.

Objectives

To establish whether the introduction of the PECARN CDR would affect CT utilisation rates for paediatric patients presenting with minor blunt head injuries to an academic hospital in Gauteng, South Africa.

Method

This was an audit of paediatric patients who presented with minor blunt head injuries and were referred for CT imaging at an academic hospital in Gauteng, compared with PECARN CDR recommendations, over a 1-year period.

Results

A total of 100 patients were referred for CT imaging. Twenty patients were classified as very low risk, none of whom had any CT findings of a TBI or ciTBI (p < 0.01). A total of 61 patients were classified as intermediate risk and 19 as high risk. In all, 23% of the intermediate and 47% of the high-risk patients had CT features of a TBI, whilst 8% and 37% had a ciTBI, respectively.

Conclusion

Computed tomography brain imaging may be omitted in patients classified as very low risk without missing a clinically important TBI. Implementing the PECARN CDR in appropriate patients would reduce CT utilisation rates.

Identification of practically important traumatic brain injury using Pediatric Emergency Care Applied Research Network rule in children younger than 2 years with minor head trauma

Background:

Minor head trauma is frequently presented to the pediatric emergency department. Despite the burden this injury poses on public health, evidence-based clinical guidelines on the assessment and management of pediatric minor head trauma remain unestablished, particularly in children below 2 years. We aimed to assess the diagnostic accuracy of a clinical decision rule (Pediatric Emergency Care Applied Research Network rule) and physician discretion in the recognition of practically important traumatic brain injury in children below 2 years of age presenting with minor head trauma to the emergency department.

Methods:

The medical records of children younger than 2 years presenting with head trauma to the emergency department were reviewed with Glasgow Coma Scale scores of 14–15. Practically important traumatic brain injury is a clinically essential traumatic brain injury including all cranial abnormalities (e.g. skull fracture) detected by computed tomography. All predictor variables of the Pediatric Emergency Care Applied Research Network rule and practically important traumatic brain injury outcomes were validated.

Results:

We enrolled and analyzed 433 children below 2 years. The most frequently observed mechanisms of injury in decreasing order were as follows: falls > 90 cm, head struck by high-impact objects, slip down, and automobile traffic accident. Of 224 children, positive findings were observed in 35 and 144 had one or more predictors of Pediatric Emergency Care Applied Research Network rule. The sensitivity, specificity, and negative likelihood ratio of the Pediatric Emergency Care Applied Research Network rule for practically important traumatic brain injury were 94.3%, 41.3%, and 0.14, respectively.

Conclusion:

The Pediatric Emergency Care Applied Research Network rule would assist in clinical decision-making to appropriately detect potential head injuries in children below 2 years, thereby reducing unnecessary performance of computed tomography scan.

Pediatric minor head trauma in Brazil and external validation of PECARN rules with a cost-effectiveness analysis

BACKGROUND

Pediatric minor head trauma approaches aim to ensure the absence of traumatic brain lesions, minimize ionizing radiation, and enhance cost control. We evaluated the applicability and cost-effectiveness of the Pediatric Emergency Care Applied Research Network (PECARN) rules after head trauma and rationalize the use of head computed tomography (CT) scans.

METHODS

We retrospectively divided patients <18 years old who presented at a single institution in Brazil with minor head trauma into four groups: Group I (skull X-ray only), Group II (head CT only), Group III (X-ray and CT), and Group IV (observation only). Direct costs were calculated based on examination and length of hospitalization. The PECARN rules were applied retrospectively in each patient to determine who required a CT scan, and the costs were re-calculated.

RESULTS

Of the 1328 patients, CT scans were performed in 36.4% and X-rays in 52.6%. The mean cost was USD 5.88, 34.58, 41.85, and 4.04 for Groups I-IV, respectively. After applying the PECARN rules, 77.6% of patients no longer required a CT scan, and overall costs were reduced from USD 16.71 to 7.88 (p < .001). Conclusion: The PECARN rules demonstrated a meaningful cost-effectiveness and should be applied to the Brazilian pediatric population.

Effect of parental pressure on emergency physicians for computerized tomography imaging request in children with head trauma

BACKGROUND

Both minor and major head traumas constitute an important proportion of childhood emergency admissions. In this study, the findings of cranial computed tomography (CCT) scans performed as a result of the parental pressure were evaluated.

METHODS

The frequency and findings of CCT scans performed as a result of parental pressure were examined in a separate subgroup.

RESULTS

A total of 227 patients were included in the study; 158 (69.9%) patients had undergone CCT scans; a pathological finding was detected in 24 (10.6%) of these patients and undergone a consultation by the neurosurgeon (most common finding was isolated linear fracture; n = 12; 50%). The patients undergoing CCT scans were divided in two subgroups: the PECARN group [n = 123 (77.8%)] and the Parental pressure group [n = 33 (22.2%)].

CONCLUSION

One third of the parents of children who presented to the emergency department with head trauma and had no indication for CCT according to PECARN rules insisted on CCT imaging, and none of these cases showed ciTBI, surgical operation, or mortality. None of the patients in the parental pressure group had a history of surgical intervention or mortality within one month after discharge.
