Comparing the WeeFIM and PEDI in neurorehabilitation for children with acquired brain injury: A systematic review

Introduction: We sought to compare the suitability of the Functional Independence Measure for Children (WeeFIM) and the Pediatric Evaluation of Disability Inventory (PEDI) as outcome measures in rehabilitation of children with acquired brain injury (ABI). Methods: We performed a systematic review of the evidence base using five databases. PRISMA guidelines were adhered to and the review was registered with the PROSPERO international prospective register of systematic reviews (registration number CRD42015025370). Results: Twenty-six retrospective studies were included. Twelve studies utilized the PEDI, thirteen studies the WeeFIM, and one study included both. Statistically significant responsiveness was demonstrated for both the WeeFIM and PEDI, although significant ceiling effects were detected. Evidence of clinically significant responsiveness was limited to one center utilizing the PEDI. Conclusion: Although requiring licensing to use, the WeeFIM is more suitable for the inpatient setting, is quicker to administer and showed minimal ceiling effects compared to the PEDI counterpart.
