The cost of childhood cancer from the family's perspective: a critical review.

The costs incurred by the families of children with cancer remain under researched. The objectives were to systematically review the literature and identify research and clinical implications. Thirteen studies were critically appraised using the Pediatric Quality Appraisal Questionnaire (PQAQ) [Ungar and Santos. Value Health 2003; 6:584-594]. Existing research indicates that families incur significant variable costs throughout cancer treatment. However, problems with the published studies related to various PQAQ domains (e.g., time horizon, sensitivity analysis) rendered the magnitude of families' childhood cancer costs somewhat uncertain. Strategies for enhancing the quality of childhood cancer cost of illness research are presented. Implications for clinical practice are discussed.
