PORTLAND, Ore., Feb. 8, 2018 /PRNewswire/ — Despite the wide availability of effective treatments for depression and a growing effort nationwide to detect and begin treating depression during primary care visits, only about one-third of individuals newly diagnosed with depression start treatment, according to a Kaiser Permanente study published today in the Journal of General Internal Medicine.
More than 16 million U.S. adults experience an episode of major depression each year, and it is one of the country’s costliest public health conditions. The annual cost of depression-related medical care and lost productivity is estimated at $210 billion.
The researchers found that out of a total of more than 240,000 patients who received a new diagnosis of depression in a primary care setting, 35.7 percent initiated antidepressant medication or psychotherapy within 90 days of their diagnosis. Among those with more severe depression, about half started treatment.
In addition, the researchers discovered stark differences between racial and ethnic groups and age groups. The odds of Asians, non-Hispanic blacks, and Hispanics starting treatment were at least 30 percent lower than non-Hispanic whites. The study also found that patients who were 60 years or older at the time of diagnosis were half as likely to begin treatment as patients under the age of 44.
“There was some older, more limited evidence that many people who are diagnosed with depression do not begin treatment, for reasons ranging from stigma to challenges accessing behavioral health services,” said Beth Waitzfelder, PhD, lead author and investigator with the Kaiser Permanente Center for Health Research in Honolulu. She added that additional evidence has shown that some patient populations are particularly vulnerable to being untreated.
“Our study, which was much larger than previous studies, provides important new evidence about the current scope of the problem among leading health care systems across the country that are striving to improve depression care in primary care settings,” said Waitzfelder. “Screening for depression in primary care is a positive step toward improving detection, treatment and outcome for depression, but disparities persist. We need a better understanding of the patient and other factors that influence treatment initiation.”
Using electronic health records, insurance claims and demographic data, the researchers studied patients who received a new diagnosis of depression in primary care settings in five large health care systems between 2010 and 2013. These organizations, including Kaiser Permanente and HealthPartners — are all members
