Over time, antidepressant use is not associated with significantly better health-related quality of life, compared to people with depression who do not take the drugs, according to a new study reported in PLOS ONE.
Depression disorder is known to have a significant impact on the health-related quality of life (HRQoL) of patients. While studies have shown the efficacy of antidepressant medications for treatment of depression disorder, these medications’ effect on patients’ overall well-being and HRQoL remains controversial.
Researchers used data on adult patients with depression drawn from the 2005-2015 United States’ Medical Expenditures Panel Survey (MEPS), a large longitudinal study that tracks the health services that Americans use. There were 17.47 million adult patients diagnosed with depression each year over the study, with two years of follow-up, and 57.6% of these received treatment with antidepressant medications.
Use of antidepressants was associated with some improvement on the mental component of SF-12 – the survey tracking health-related quality of life. However, when this positive change was compared to the change in group of people who were diagnosed with depressive disorder but did not take antidepressants, there was no statistically significant association of antidepressants with either the physical (p=0.9595) or mental (p=0.6405) component of SF-12. In other words, the change in quality of life seen among those on antidepressants over two years was not significantly different from that seen among those not taking the drugs.
The study was not able to separately analyse any subtypes or varying severities of depression. Future studies should investigate the use of non-pharmacological depression interventions used in combination with antidepressants, said the researchers.
The authors noted that, “Although we still need our patients with depression to continue using their antidepressant medications, long-term studies evaluating the actual impact for pharmacological and non-pharmacological interventions on these patients’ quality of life is needed. With that being said, the role of cognitive and behavioural interventions on the long term-management of depression needs to be further evaluated in an effort to improve the ultimate goal of care for these patients; improving their overall quality of life.”
