Step 1: Identify the clinical priority. This patient has major depression plus several high-risk suicide factors - male sex, divorced (lack of social support), alcohol use, and active passive suicidal ideation ("what is the point in living"). Safety always comes first in psychiatric emergencies.
Step 2: Assess suicide risk. The mnemonic SAD PERSONS (Sex-male, Age, Depression, Previous attempt, Ethanol/alcohol, Rational thinking loss, Social support lacking, Organised plan, No spouse, Sickness) flags multiple risk factors here. A patient verbalising suicidal ideation with depression, alcohol dependence and no social support is at imminent risk.
Step 3: Choose management. The immediate priority for an actively suicidal high-risk patient is to ensure safety, which means inpatient hospitalisation for observation, stabilisation and initiation of treatment.
Step 4: Why the others are wrong. CBT and antidepressants are essential parts of definitive treatment but take days to weeks to act and do not address immediate risk - they are started after the patient is in a safe setting. Calling it a normal part of life is dismissive and dangerous. Hence, hospitalise the patient first.
