This study aimed to investigate general factors associated with prognosis regardless of the type of treatment received, for adults with depression in primary care.

We searched Medline, Embase, PsycINFO and Cochrane Central (inception to 12/01/2020) for RCTs that included the most commonly used comprehensive measure of depressive and anxiety disorder symptoms and diagnoses, in primary care depression RCTs (the Revised Clinical Interview Schedule: CIS-R). Two-stage random-effects meta-analyses were conducted.

Twelve (n = 6024) of thirteen eligible studies (n = 6175) provided individual patient data. There was a 31% (95%CI: 25 to 37) difference in depressive symptoms at 3–4 months per standard deviation increase in baseline depressive symptoms. Four additional factors: the duration of anxiety; duration of depression; comorbid panic disorder; and a history of antidepressant treatment were also independently associated with poorer prognosis. There was evidence that the difference in prognosis when these factors were combined could be of clinical importance. Adding these variables improved the amount of variance explained in 3–4 month depressive symptoms from 16% using depressive symptom severity alone to 27%. Risk of bias (assessed with QUIPS) was low in all studies and quality (assessed with GRADE) was high. Sensitivity analyses did not alter our conclusions.

When adults seek treatment for depression clinicians should routinely assess for the duration of anxiety, duration of depression, comorbid panic disorder, and a history of antidepressant treatment alongside depressive symptom severity. This could provide clinicians and patients with useful and desired information to elucidate prognosis and aid the clinical management of depression.

Antidepressant drugs are widely used in the treatment of depression in people with chronic physical health problems.

To examine evidence related to efficacy, tolerability and safety of antidepressants for people with depression and with chronic physical health problems.

Meta-analyses of randomised controlled efficacy trials of antidepressants in depression in chronic physical health conditions. Systematic review of safety studies.

Sixty-three studies met inclusion criteria (5794 participants). In placebo-controlled studies, antidepressants showed a significant advantage in respect to remission and/or response: selective serotonin reuptake inhibitors (SSRIs) risk ratio (RR) = 0.81 (95% CI 0.73–0.91) for remission, RR = 0.83 (95% CI 0.71–0.97) for response; tricyclics RR = 0.70 (95% CI 0.40–1.25 (not significant)) for remission, RR = 0.55 (95% 0.43–0.70) for response. Both groups of drugs were less well tolerated than placebo (leaving study early due to adverse effects) for SSRIs RR = 1.80 (95% CI 1.16–2.78), for tricyclics RR = 2.00 (95% CI 0.99–3.57). Only SSRIs were shown to improve quality of life. Direct comparisons of SSRIs and tricyclics revealed no advantage for either group for remission, response, effect size or tolerability. Effectiveness studies suggest a neutral or beneficial effect on mortality for antidepressants in participants with recent myocardial infarction.

Antidepressants are efficacious and safe in the treatment of depression occurring in the context of chronic physical health problems. The SSRIs are probably the antidepressants of first choice given their demonstrable effect on quality of life and their apparent safety in cardiovascular disease.

The relative efficacy of different psychological treatments for chronic post-traumatic stress disorder (PTSD) is unclear.

To determine the efficacy of specific psychological treatments for chronic PTSD.

In a systematic review of randomised controlled trials, eligible studies were assessed against methodological qualitycriteria and data were extracted and analysed.

Thirty-eight randomised controlled trials were included in the meta-analysis. Trauma-focused cognitive-behavioural therapy (TFCBT), eye movement desensitisation and reprocessing (EMDR), stress management and group cognitive-behavioural therapy improved PTSD symptoms more than waiting-list or usual care. There was inconclusive evidence regarding other therapies. There was no evidence of a difference in efficacy between TFCBT and EMDR butthere was some evidence that TFCBT and EMDR were superior to stress management and other therapies, and that stress management was superior to other therapies.

The first-line psychological treatment for PTSD should be trauma-focused (TFCBTor EMDR).

Treatment options for depression include antidepressants, psychological therapy and a combination of the two.

To develop cost-effective clinical guidelines.

Systematic literature reviews were used to identify clinical, utility and cost data. A decision analysis was then conducted to compare the benefits and costs of antidepressants with combination therapy for moderate and severe depression in secondary care in the UK.

Over the 15-month analysis period, combination therapy resulted in higher costs and an expected 0.16 increase per person in the probability of remission and no relapse compared with antidepressants. The cost per additional successfully treated patient was £4056 (95% CI 1400–18 300); the cost per quality-adjusted life year gained was £5777 (95% CI 1900–33 800) for severe depression and £14 540 (95% CI 4800–79 400) for moderate depression.

Combination therapy is likely to be a cost-effective first-line secondary care treatment for severe depression. Its cost-effectiveness for moderate depression is more uncertain from current evidence. Targeted combination therapy could improve resource utilisation.
