Background Depression is a major individual and public-health burden throug
hout the world and is managed mainly in primary care. The most effective st
rategy to reduce this burden has been believed to be education of primary-c
are practitioners. We tested this assumption by assessing the effectiveness
of an educational programme based on a clinical-practice guideline in impr
oving the recognition and outcome of primary-care depression.
Methods We carried out a randomised controlled trial in a representative sa
mple of 60 primary-care practices (26% of the total) in an English health d
istrict. Education was delivered to practice teams and quality tested by fe
edback from participants and expert raters, The primary endpoints were reco
gnition of depression, defined by the hospital anxiety and depression (HAD)
scale, and improvement. Analysis was by intention to treat.
Findings The education was well received by participants, 80% of whom thoug
ht it would change their management of patients with depression. 21 409 pat
ients were screened, of whom 4192 were classified as depressed by the HAD s
cale. The sensitivity of physicians to depressive symptoms was 39% in the i
ntervention group and 36% in the control group after education (odds ratio
1.2 [95% CI 0.88-1.61]). The outcome of depressed patients as a whole at 6
weeks or 6 months after the assessment did not significantly Improve.
Interpretation Although well received, this in-practice programme, which wa
s designed to convey the current consensus on best practice for the care of
depression, did not deliver improvements in recognition of or recovery fro
m depression.
