Study looks at link between substance abuse, PTSD and mortality
Veterans suffering from posttraumatic stress disorder who are also battling drug or alcohol problems face a higher risk of death, according to new research
from the VA Ann Arbor Healthcare System and the University of Michigan Health System.
The new study is the first to examine the association between drug or alcohol use disorders and death in Veterans with PTSD, and also includes data from
the nation's youngest Veterans who have returned from Iraq and Afghanistan.
Dr. Kipling Bohnert, the study's lead author, said the research sheds new light on the importance of treating both substance use and posttraumatic stress
disorders in Veterans.
"Attention needs to be paid to Veteran patients with PTSD, with an emphasis on identifying those who might also have a problem with drug or alcohol use,"
said Bohnert, who is a post-doctoral fellow at VA Ann Arbor and a research fellow at the University of Michigan. "This study highlights the potential
importance of effective treatment for both conditions in helping Veterans after they've returned from conflict."
Previous research on Veterans has linked PTSD with higher risks of death, but the Ann Arbor study is the first to highlight the association between
substance use disorders, PTSD and mortality. The study was published online in the journal Drug and Alcohol Dependence.
While the researchers found a significant link between substance use disorders and death in Veterans with
PTSD across all ages, they also found that the association was most pronounced for the youngest group of Veterans, including those from the conflicts in
Iraq and Afghanistan.
The youngest Veterans, those 45 and under, showed a particularly strong link between substance use disorders and both injury- and non injury-related death.
Injury-related death included homicides, suicides and accidents, while non injury-related deaths included heart disease, cancer and other health problems.
Bohnert said more research is necessary to figure out why younger Veterans exhibit a stronger tie between substance use disorders and death.
Dr. Federic C. Blow, the paper's senior author and director of VA's National Serious Mental Illness Treatment Research & Evaluation Center, said the
research might be helpful for physicians in deciding the best way to treat their patients.
"In theory," Blow said, "a treatment program that addresses both issues—substance use and PTSD—should reduce the risk of death from all causes, and this
may be especially true for the nation's youngest Veterans."
