MRCEM OSCE: Mental State Examination – Acute Severe Depression

 Mental State Examination in Acute Severe Depression

1. Understanding the Station

In the MRCEM OSCE, a mental state examination (MSE) station on acute severe depression assesses your ability to:

• Recognise and assess severe depressive symptoms.

• Conduct an appropriate and empathetic mental health interview.

• Identify risk factors (especially suicidal ideation or self-harm).

• Demonstrate safe and effective management and referral.

You are not expected to perform a comprehensive psychiatric assessment, but rather to demonstrate structured, safe, and compassionate acute care skills.

2. Approach at the Start

• Introduction & rapport building:

  • “Hello, I’m Dr.Mehdi one of the emergency doctors. I understand you’ve been feeling very low recently — can you tell me a bit about what’s been happening?”

• Check immediate safety and comfort.

  • Ensure privacy, calm tone, and non-judgmental demeanor.

• Observe appearance and behavior from the outset — note poor eye contact, psychomotor slowing, tearfulness, neglect of self-care.

3. Structure of the Mental State Examination (MSE)

You can use the mnemonic “ASEPTIC” as a guide:

4. Risk Assessment (Critical Component)

Always assess suicidal ideation clearly and sensitively:

• “Have you had thoughts that you would be better off dead?”

• “Have you made any plans to harm yourself?”

• “Do you have access to any means (medication, weapons, etc.)?”

Identify protective factors (family, faith, pets, responsibilities).

---

5. Management in the ED

• Ensure immediate safety — remove harmful objects, close observation.

• Assess physical health (screen for medical causes or overdose).

• Involve psychiatry liaison team urgently for full assessment.

• Do not discharge without a mental health risk review.

• Provide reassurance and clear communication:
  “You’ve done the right thing coming in — we’ll make sure you get the right help and support.”

---

6. Communication Skills

Demonstrate:

• Empathy and active listening.

• Non-judgmental tone.

• Use of silence appropriately.

• Avoid medical jargon.

• Validate the patient’s feelings (“That sounds really difficult.”)

---

7. Common Pitfalls to Avoid

• Rushing through the station without empathy.

• Failing to assess for suicidal intent.

• Ignoring psychotic symptoms or severe risk indicators.

• Not explaining the next steps clearly.

---

8. Example Closing Summary

“From what you’ve told me, it sounds like you’ve been feeling very low, hopeless, and having thoughts of ending your life. I’m really concerned about your safety. I’d like to get our mental health team involved straightaway to support you, and we’ll keep you safe here in the meantime.”

You are asked to perform an appropriate mental state examination and assess suicide risk.

 

SECTION 1: What to Ask / Say to the Patient

Introduction

“Hello, I’m Dr. Mehdi one of the emergency doctors. I understand you’ve been feeling very low recently. Is it okay if we talk a bit about how you’ve been feeling so I can understand what’s going on and how best to help you?”
“Before we start, could I confirm your name and that you’re comfortable to speak here in private?”
“Everything we discuss will remain confidential unless I’m worried about your safety — is that alright?”

---

Appearance & Behaviour

(Observe quietly — then ask if appropriate)
“Have you been managing to take care of yourself — things like eating, sleeping, and getting dressed?”

---

Speech

“I notice you’re speaking quite softly — have you been feeling tired or low in energy?”

---

Mood and Affect

“How have you been feeling lately, in your own words?”
“On a scale of 1 to 10, where 10 is feeling great and 1 is feeling awful, how would you rate yourself?”
“Have you been able to enjoy things you normally like doing?”

---

Thought Content (Depression and Suicide Risk)

“When people feel very low, they sometimes think life isn’t worth living. Have you felt like that?”
“Have you had any thoughts of harming yourself or ending your life?”
“Have you made any plans or tried to act on those thoughts?”
“Do you have access to anything you might use to harm yourself, like tablets or sharp objects?”
“What has stopped you from acting on those thoughts?”

(Pause and show empathy.)

“That must be really difficult — thank you for trusting me with that.”

---

Perception

“Sometimes when people are feeling very low, they might hear voices or see things that others can’t. Has that happened to you?”

---

Cognition

“How have you been sleeping?”
“How’s your appetite been recently?”
“Have you been able to concentrate on reading or watching TV?”

---

Insight

“Do you feel that you might need some professional help for how you’re feeling?”
“Have you ever had treatment for depression or low mood before?”

---

Closure

“Thank you for talking with me — I know that wasn’t easy.
My main concern right now is your safety.
We’ll make sure you’re not left alone and that you get to see our mental health team today.
You’ve done the right thing by coming in, and we’ll make sure you get the support you need.”

SECTION 2: What to Say to the Examiner (Summary and Management)

“I have just assessed Mr Tom presenting with features consistent with acute severe depression.”

“On mental state examination:

• The patient appeared withdrawn, poorly groomed, with psychomotor retardation.

• Speech was slow and quiet.

• Mood was pervasively low with congruent affect.

• Thought content was dominated by hopelessness and guilt.

• The patient expressed suicidal ideation with some planning, but no attempt yet.

• No perceptual disturbances were elicited.

• Cognition is intact, though concentration is poor.

• Insight is present; the patient recognises they need help.”

---

“My working impression is acute severe depression with suicidal ideation.”

---

“In terms of immediate management in the ED:

• I would ensure the patient is in a safe environment, remove potential means of self-harm, and maintain close nursing observation.

• I would perform basic physical observations and screen for overdose or medical causes (e.g., hypoglycaemia, thyroid disorder, substance use).

• I would involve the psychiatric liaison team urgently for full assessment and risk management.

• The patient would not be discharged until reviewed by the mental health team.

• I would provide reassurance, maintain rapport, and document the full assessment clearly.”
