Applicability of the CATCH, CHALICE and PECARN paediatric head injury clinical decision rules: pilot data from a...

Area of Science:

• Pediatric Emergency Medicine
• Clinical Decision Science
• Trauma Care

Background:

• Clinical decision rules (CDRs) aid in identifying pediatric head injury (HI) patients at risk for traumatic brain injury.
• Key CDRs include Canadian assessment of tomography for childhood head injury (CATCH), Children's head injury algorithm for the prediction of important clinical events (CHALICE), and Pediatric Emergency Care Applied Research Network (PECARN).
• These CDRs target different pediatric HI cohorts and have not been directly compared in the same clinical setting.

Purpose of the Study:

• To quantify the proportion of pediatric head injury patients to whom each of the three major CDRs (CATCH, CHALICE, PECARN) is applicable.
• To provide data for informed selection and implementation of CDRs in pediatric emergency departments.

Main Methods:

• Prospective enrollment of consecutive children presenting with HI to an Australian pediatric Emergency Department.
• Collection of published inclusion/exclusion criteria and predictor variables for CATCH, CHALICE, and PECARN CDRs.
• Determination of the applicability frequency of each CDR based on collected patient data.

Main Results:

• Out of 949 analyzed patients, no single CDR was applicable to all children with HI.
• The CHALICE CDR was applicable to the highest proportion of patients (97%).
• The CATCH CDR was applicable to the fewest (26%), while PECARN showed applicability to 76% of patients under 2 years and 74% of those aged 2 to 18 years.

Conclusions:

• Each CDR demonstrates varying applicability across different pediatric head injury populations.
• Direct comparison of CDRs is challenging due to differing applicability.
• Further validation, performance accuracy, usability, and cost-effectiveness analyses are recommended before implementing any specific CDR.
