WASHINGTON, Aug. 10 (Xinhua) -- A new model of
treatment for bipolar disorder, similar to care given to diabetics and others
with chronic diseases, improved patient outcomes without increasing costs,
according to a new research by U.S. psychiatrists published on Thursday.
Results appear in two reports published in
Psychiatric Services, a journal of the American Psychiatric Association.
The new care model for bipolar disorder tested in
veterans across the nation reduced their manic episodes and improved their
quality of life.
The randomized, controlled trial also showed that the
model did not add to the treatment costs for bipolar disorder, which affects
nearly 6 million American adults a year.
"We applied the same symptom management approaches
found in interventions for diabetes and asthma to the treatment of bipolar
disorder and found that people with serious mental illness can help take control
of their care," said Mark S. Bauer, staff psychiatrist with the Providence
Veterans Affairs Medical Center.
"This finding should reduce the stigma of
helplessness that so often is associated with these disorders, and it will open
new avenues for the treatment of bipolar disorder," the psychiatrist added.
Bauer, who oversaw the clinical trial, is the lead
author of both journal articles.
The new model was developed and tested in veterans
with bipolar disorder at the Providence V.A. Medical Center.
During the trial, 306 veterans were enrolled at 11
V.A. centers located in 10 U.S. states.
Each veteran was randomly assigned to a study group.
One group got usual care through their psychiatrist. The other group received
treatment under the new model.
The model brings together psychiatrists and nurses as
a team to treat the patients. Psychiatrists monitored symptoms and handled
medications. Nurse care coordinators worked with veterans during group education
sessions.
During the weekly group sessions, nurses discussed
topics such as medication side effects and early warning signs for symptoms,
which in bipolar disorder range from bursts of optimism and impulsive behavior
during manic episodes to fatigue, social withdrawal and suicidal thoughts during
depressive episodes.
During the sessions, patients discussed coping
skills, got feedback from the group and created personal action plans.
The intervention was tested for three years. The
results: Under the new model, patients saw a significant reduction in symptoms,
including five fewer weeks experiencing mania during the three-year study
period.
Patients also felt happier and healthier, reporting
more productive time at work, better relations with family, and more
satisfaction with their care.
The new model was less expensive - an average of
61,398 U.S. dollars for three years of direct treatment costs compared with
64,379 dollars for usual care - although the difference was not statistically
significant.
"The bottom line is that we saw improvements in
patients' symptoms, function and quality of life with no change in net costs,"
Bauer said. Enditem
