The impact of liver disease on health-related quality of life: a review of the literature.

Quality of life as an outcome variable has become an important measure in clinical research. Making a transition from a "biomedical model" of health to one that incorporates the social aspects of disease, clinicians and researchers dealing with chronic illness now incorporate quality-of-life measures into clinical practice and research.
