September 10th is Suicide Prevention Day. Approximately 10 Canadians die by suicide every day. Suicide is currently ranked as the 9th leading cause of death. According to the Canadian Community Health Survey, 14.7% of the population has thought about suicide and 3.5% have attempted suicide in their lifetime.
Here are some resources on suicide and depressive disorders selected by Joule’s Ask a Librarian team using a variety of tools included with CMA membership.

Major Depressive Disorder
- Hospitalization or immediate specialist consultation is usually needed for patients who pose a serious threat of harm to self or others (Strong recommendation) and should be considered for those that are severely depressed, especially if they lack social supports or have a complicating medical or psychiatric conditions.
Recommended initial treatment choices:
- For mild-to-moderate depression in adults:
- psychotherapy is recommended as an initial treatment option in most cases (Strong recommendation)
- consider antidepressants as an alternative initial therapy in some cases (Weak recommendation)
- a prior history of moderate or severe depression
- subthreshold symptoms lasting ≥ 2 years
- consider a combination of psychotherapy plus an antidepressant if there are comorbid psychosocial problems (Weak recommendation)
- For moderate-to-severe depression use a combination of an antidepressant plus psychotherapy (Strong recommendation):
- Consider electroconvulsive therapy (ECT) for severe depression if the patient is unresponsive to psychotherapy plus antidepressants or if there is an urgent need for rapid response (suicidal, food refusal, catatonic) (Weak recommendation).
- For most patients, optimal medications include selective serotonin reuptake inhibitors (SSRIs), serotonin-norepinephrine reuptake inhibitors (SNRIs), mirtazapine, or bupropion (Strong recommendation).
- if patient is pregnant or lactating, individualize medical treatment if psychotherapy has failed as sole treatment.
- Among important adverse events of antidepressant therapy, there is an increased risk of suicidality, generally in the first 1-2 months of treatment, in young adults aged 18-24 years.

Synopsis of clinical studies in POEMs by Essential Evidence Plus:
POEM: CBT effective in adolescents with depression who don't want medication
In adolescents who eschew drug treatment of major depression, short-term cognitive behavioral therapy (CBT) is more effective than treatment as usual in inducing recovery, with a number needed to treat of 4 to 10. CBT also produced faster results. (LOE = 1b)
