Applying the Patient-Reported Outcomes Measurement Information System to Assess Upper Extremity Function among Children with Congenital Hand Differences.

Abstract

Few studies have evaluated self-assessment tools among children with congenital hand differences. The authors compared three upper extremity disability instruments with the Patient-Reported Outcomes Measurement Information System (PROMIS) Pediatric Upper Extremity Item Bank. Thirty-three children (aged 6 to 17 years) with congenital hand differences completed the Pediatric Outcomes Data Collection Instrument; the Michigan Hand Outcomes Questionnaire; the Disabilities of the Arm, Shoulder, and Hand questionnaire; and the PROMIS Upper Extremity short form and computerized adaptive test. Hand function was also assessed, and construct validity and feasibility were examined. PROMIS demonstrated good construct validity. Short form and computerized adaptive test were highly correlated with Disabilities of the Arm, Shoulder, and Hand questionnaire scores (r = 0.80, p < 0.001) and Pediatric Outcomes Data Collection Instrument domains (r = 0.70, p < 0.001). PROMIS was moderately correlated with the Michigan Hand Outcomes Questionnaire (r = 0.40, p < 0.05). PROMIS scores also correlated with grip (r = 0.60, p < 0.001) and pinch strength (r = 0.50, p < 0.001). Compared with the Pediatric Outcomes Data Collection Instrument and the Disabilities of the Arm, Shoulder, and Hand and Michigan Hand Outcomes questionnaires, PROMIS required the least time to complete with fewer children requiring assistance. The Patient-Reported Outcomes Measurement Information System is highly correlated with both functional assessment and self-reported function among children with congenital hand differences.
