title: Quality of life of children following bone marrow transplantation: critical review of the research literature.
abstract: Children's quality of life (QOL) following bone marrow transplant (BMT) is an important but poorly understood concept. The aim of this paper is to critically review all research study designs to determine the QOL of childhood BMT recipients and to identify implications for research, practice and theory. The studies' methodological quality was evaluated separately by two investigators according to a set of formal criteria modified from Hoodin and Weber (Psychosomatics 44 (2003) 181). The review yielded one retrospective, one cross-sectional, six descriptive surveys and two prospective longitudinal study designs. The studies included 568 childhood BMT recipients ranging from 0.8 to 33 years. Only one study used a generic and disease-specific, psychometrically sound, QOL measure. Timing of assessments ranged from pre-BMT to 21 years following BMT. Due to the poor methodological quality, rendering conclusions across the studies was challenging. While the available evidence seems to suggest children experience good QOL following BMT, several studies found BMT to have a negative impact on various aspects of QOL. These results appear to be influenced by timing and type of measurements undertaken. Ultimately, there is a need for larger, more methodologically rigorous trials using prospective longitudinal study designs with pre- and post-measures to examine all QOL domains in children.
