Vaso-occlusive painful events in sickle cell disease: impact on child well-being

Area of Science:

• Pediatric Hematology
• Quality of Life Research
• Clinical Trial Methodology

Background:

• Sickle cell disease (SCD) frequently causes painful events that can affect a child's health-related quality of life (HRQL).
• Generic HRQL measures need validation for responsiveness in specific pediatric populations like SCD.
• This study investigates the impact of painful events on HRQL in children with SCD.

Purpose of the Study:

• To assess how painful events affect the HRQL of children with SCD.
• To determine the responsiveness of the PedsQL™ 4.0 Acute Version Generic Core Scales in children with SCD during painful events.
• To evaluate HRQL changes from emergency department presentation to post-discharge.

Main Methods:

• A prospective cohort study involving 57 children with SCD.
• HRQL was measured using the PedsQL™ 4.0 Acute Version Generic Core Scales (child self-report and caregiver proxy-report).
• Measurements were taken at presentation for a painful event and 7 days post-discharge, with comparisons to historical SCD controls.

Main Results:

• Children with SCD reported significantly lower HRQL scores during painful events compared to historical controls across most domains.
• Caregiver proxy-reports also showed significantly lower HRQL scores, except for social and school functioning.
• HRQL scores improved significantly by 7 days post-discharge, returning to levels similar to historical controls.

Conclusions:

• The PedsQL™ 4.0 is a responsive and useful tool for measuring HRQL changes in children with SCD.
• Painful events substantially impair all domains of HRQL in children with SCD.
• HRQL demonstrates significant improvement within 7 days after the resolution of a painful event.
