The effects of anti-depressants on depression symptom scores at 12 months follow-up in patients with cardiometabolic disease: Results from a large primary care cohort.
BACKGROUND
Evidence on the long-term usefulness of anti-depressants in managing depression in cardiometabolic disease is limited.


OBJECTIVE
We examined the effects of anti-depressant prescribing on depressive symptoms at 12 months follow-up in patients with cardiometabolic disease and a positive depression screening result at baseline.


METHODS
We retrospectively reviewed routine UK primary care data for patients with coronary heart disease, diabetes and previous stroke for the year 2008-2009. 35,537 patients with one of the three above diseases underwent depression screening using the Hospital Anxiety and Depression Scale (HADS-D). Of 7080 patients with a positive screening result (HADS-D ≥ 8), 3933 (55.5%) patients had a repeat HADS-D recorded at 12 months follow-up.


METHODS
We compared the change in HADS-D at follow-up and remission rate in those who were prescribed anti-depressants (n = 223) against those who were not (n = 3710).


RESULTS
The mean change in HADS-D from baseline, for the nonprescribed group was similar to the reduction observed in patients who were continuously prescribed (n = 93) with anti-depressants during follow-up. Patients who were prescribed intermittently (n = 72) or only one (n = 58) prescription during follow-up had a lower reduction in HADS-D compared to the nonprescribed group. There was no difference in remission rates between continuously prescribed and the nonprescribed group, but remission was lower in patients prescribed intermittently and single prescription.


CONCLUSIONS
Improvement in depressive symptoms in patients with cardiometabolic disease at 12 months was not any better in patients prescribed with anti-depressants compared to the nonprescribed group. The role of anti-depressants in the management of depression in cardiometabolic disease merits further investigation.
