Systematic Review of Pain Assessment Measures Used in Pediatric Acute Lymphoblastic Leukemia.

Background: Pain is a prevalent, frequent, and often persistent symptom among children with acute lymphoblastic leukemia (ALL). Despite its high prevalence, pain has remained understudied, and no evidence-based recommendations exist for how best to assess and treat pain in this population. Without proper assessment, clinical efforts to improve pain management in pediatric ALL will be ineffective.

Aims: Therefore, the purpose of this systematic review is to describe and identify gaps in measurement approaches that have been used to assess pain in pediatric ALL, evaluate the psychometric properties of available pediatric pain measures, and provide recommendations for clinical research and practice.

Methods: Literature searches were performed following Cochrane and PRISMA guidelines for systematic reviews. Domains of pain assessed, measures used to assess pain, measure format, respondent, and timing of pain assessment were extracted from studies that met inclusion criteria. The psychometric properties of included measures were then evaluated. A total of 238 full-text articles were screened and 123 met inclusion criteria.

Results: Most studies assessed pain using generic health-related quality of life instruments rather than pain-specific measures. A total of 39 measures were used across the 123 included studies, and the psychometric properties of the measures varied considerably.

Conclusions: Recommendations include a selection of well-validated pain assessment measures that are currently available and can be used to facilitate best practices in ALL pain assessment. Clinicians and investigators are encouraged to utilize a multidimensional pain assessment approach to inform and enhance pain care in pediatric ALL.
