Assessing recovery and disability after physical trauma: the Pediatric Injury Functional Outcome Scale

Area of Science:

• Pediatric Traumatology
• Rehabilitation Medicine
• Child Psychology

Background:

• Assessing functional recovery in children post-injury is crucial for effective rehabilitation.
• Existing tools may not adequately capture the multifaceted nature of pediatric injury outcomes.
• A brief, reliable, and valid scale is needed to evaluate recovery across various domains.

Purpose of the Study:

• To establish the reliability and validity of the Pediatric Injury Functional Outcome Scale (PIFOS).
• To assess the scale's utility in capturing functional outcomes following pediatric traumatic brain injury (TBI) and orthopedic injury (OI).

Main Methods:

• A prospective longitudinal study involving parents of children aged 3-15 years.
• The PIFOS structured interview was administered at 3 and 12 months post-hospitalization for TBI or OI.
• Statistical analyses, including internal consistency, inter-rater reliability, and generalized linear modeling, were performed.

Main Results:

• The PIFOS demonstrated good internal consistency (α = .90-.93) and inter-rater reliability (α = .90).
• The scale showed significant correlations with injury severity and neurodevelopmental outcomes.
• PIFOS was sensitive to injury type/severity and responsive to changes within the first year post-injury, identifying specific difficulties in both TBI and OI groups.

Conclusions:

• The PIFOS is a reliable and valid instrument for assessing functional outcomes in children after TBI and OI.
• The scale is useful for evaluating recovery in both natural history and intervention studies.
• Findings highlight persistent challenges in coordination, emotionality, social participation, and discomfort in pediatric injury survivors.
