Fibrosis Of Lungs
The quality of well-being scale (QWB) has been used to measure overall
life quality in a number of different clinical conditions, including
cystic fibrosis and chronic obstructive pulmonary disease. Evidence
supports its validity and reliability in both cross-sectional and
longitudinal studies. One of the strengths of the QWB is that it is not
organ-specific, so that it can take into account the broad impact of a
disease and/or intervention, including unanticipated effects. The
well-year of life is a concept that includes both morbidity and
mortality: if a disease reduces quality of life by one-half, over a
period of two years, that person can be said to have lost one full
well-year. As we examine the impact of diseases such as cystic fibrosis,
and of interventions such as lung transplantation, it is important to
consider changes in overall well-being over time to help individual
patients and families make difficult therapeutic choices and to help
formulate health policy.
