Chicago - Investing in depressed employees - quickly getting them treatment and even offering telephone psychotherapy - can cut absenteeism while improving workers' health, a study suggests.
Many employers view mental health coverage as a financial black hole, but the study shows that spending money on depression is a smart business move, said researcher Dr Philip Wang. Wang works for the US National Institute of Mental Health, which funded the study.
Employees who got the aggressive intervention worked on average about two weeks more during the yearlong study than those who got the usual care. The typical approach is to advise such employees to see their doctor or seek a mental health specialist.
Also, more workers in the intervention group were still employed by year's end - 93% vs 88% - savings that helped employers avoid hiring and training costs, the researchers said.
In addition, intervention employees were almost 40% more likely to recover from depression during the yearlong study, which is reported in Wednesday's Journal of the American Medical Association.
Good medical, business sense
The researchers have not finished a formal cost-benefits analysis, but early results suggest savings from more hours worked averaged to about $1 800 per employee. That far exceeds the program's initial $100 to $400 per worker cost. The benefits also likely exceed other costs, including drugs and therapy too, the researchers said.
"We knew before that treating depression makes good medical sense. This suggests that it makes good business sense," said Dr Thomas Insel, director of the institute.
The percentage of workers who improved substantially - 31% - or who recovered - 26% - was low even in the intervention group. That was comparable to the rate of improvement in other studies of people with depression.
The results are important because depression takes a hefty toll on the US workplace, affecting about 6% of employees each year and costing more than $30bn annually in lost productivity, said study co-author Ronald Kessler, a Harvard Medical School researcher. Kessler has worked as a paid consultant for several drug companies, including makers of antidepressants.
Two other co-authors are employees of United Behavioural Health, the large managed-care company involved in the study, and own stock in UBH's parent company. The research compared UBH's usual mental health coverage with the experimental telephone-based outreach program devised for the research.
Mental health insurance
Because of the study's results, UBH began offering a similar program after the study ended more than a year ago.
Dr Ken Duckworth, medical director of the non-profit National Alliance on Mental Illness, praised the research as "a real advance".
"This study shows employers benefit" from paying attention to depression, Duckworth said. His group supports a bill before the US Congress that would require employers to offer mental health insurance coverage that is equal to that provided for physical illnesses, when policies cover both.
The study involved 604 white-collar and blue-collar workers at 16 large US companies. Employees included pilots, lawyers, bankers, truckers and janitors.
The study volunteers answered an online screening questionnaire that found signs of depression. Half got the usual care, including a letter suggesting they contact their primary-care doctor or call UBH for referral to a mental health specialist.
Held onto job
The intervention group got repeated telephone calls during non-work hours from UBH case managers trained in mental health treatment. Case managers urged workers to get treatment and called periodically to see how it was going.
When workers resisted seeking help, case managers offered telephone psychotherapy, which many employees viewed as less stigmatising and more convenient than office visits with a psychiatrist, Kessler said.
About 40% of workers in both groups got antidepressants. Intervention group workers were 60% more likely to get treatment from a mental health specialist.
More employees in the treatment group stayed employed, a savings for the company.
