This is an iatroX educational summary of named Canada sources, not an official guideline. It does not replace the complete source documents, local policy, specialist advice or clinical judgement. The evidence source is pan-Canadian, but formularies, funded access, referral routes, public-health directions and service availability remain provincial or territorial.

Source and scope

This summary is bounded to the recommendations, population and decisions covered by 2023 update on clinical guidelines for management of major depressive disorder in adults. Apply it with the current provincial or territorial pathway where implementation differs.

Source-attributed clinical priorities

  • Assess suicide risk, bipolar-spectrum features, psychosis, substance use, medical contributors and functional impairment before selecting treatment.
  • Match psychotherapy, pharmacotherapy and combined care to severity, prior response, preference, comorbidity and access.
  • Measure symptoms and function during follow-up, optimize an adequate trial and use the CANMAT sequence when response is insufficient.
  • Ask directly about previous hypomania or mania because an unrecognized bipolar course changes treatment selection.

Practical assessment and management workflow

1
Record baseline depressive symptoms, functioning, sleep, appetite, cognition and safety with a reproducible measure.
2
Clarify episode duration, recurrence, seasonality, perinatal context, medications and relevant physical illness.
3
Agree on psychotherapy, medication, exercise and social interventions that are feasible for the person.
4
Review early for tolerability and safety, then document remission, residual symptoms and relapse-prevention needs.

Safety, red flags and urgent escalation

  • Arrange urgent assessment for imminent suicide risk, psychotic depression, catatonia or inability to maintain nutrition and hydration.
  • Monitor for activation, emergent suicidality, serotonin toxicity, withdrawal and medication interactions.
  • Do not stop an effective antidepressant abruptly; plan a gradual, monitored change when discontinuation is chosen.
