Pain, mood disturbance, and quality of life in patients with multiple myeloma.
OBJECTIVE
To determine the levels of pain intensity and pain interference in patients with multiple myeloma, the relationship between pain and mood disturbance, and factors that influence quality of life (QOL).


METHODS
Descriptive correlational mailed survey.


METHODS
A private tertiary institution in the Midwest.


METHODS
Convenience sample of 346 adult patients with multiple myeloma identified through an institutional database, 206 of whom responded to the surveys.


METHODS
Mailed, self-administered questionnaires: Brief Pain Inventory Short Form, Profile of Mood States, QOL Scale (Cancer Patient Version), and a demographic tool. Treatment details were obtained from the database on subjects consenting to participate.


METHODS
Pain intensity, pain interference, psychologic functioning, and QOL.


RESULTS
29% (n = 60) of subjects reported moderate to severe pain intensity. Significant associations were found between pain intensity and mood disturbance scores. As pain interference increased, so did levels of mood disturbance. A joint predictive model explained 74.6% of the variability in total QOL scores.


CONCLUSIONS
Cancer pain remains undertreated, and patients with myeloma are no exception. Pain and mood disturbance scores were significant predictors of QOL in this group of patients. Subjects with multiple myeloma reported higher levels of mood disturbance than patients with cancer from other studies.


CONCLUSIONS
The oncology nurse is in a key position to facilitate ongoing, adequate pain and psychosocial assessment of patients with myeloma. Further study is needed to determine if control of pain and mood disturbance factors has a positive effect on the various domains of QOL.
