CASC Risk Assessment: How to Score Full Marks Every Time

Risk assessment is a core competency tested across multiple CASC stations. Whether the station is explicitly about risk or not, examiners expect you to screen for and manage risk appropriately. Studies of CASC outcomes consistently show that risk assessment is one of the most common areas where candidates lose marks — often because they avoid it rather than because they do it poorly.

Understanding Risk Assessment in CASC

Risk assessment in the CASC exam goes beyond simply asking "Do you have thoughts of harming yourself?" It requires a nuanced, systematic approach that considers multiple domains, integrates the patient's narrative, and results in a clear formulation with actionable management.

Examiners assess whether you can: - Identify relevant risk factors systematically - Ask about risk sensitively and directly - Integrate risk into the broader clinical picture - Formulate risk clearly with supporting evidence - Develop a proportionate management plan - Communicate risk to the patient and to other professionals

The Risk Framework: Static, Dynamic, and Protective Factors

Every risk assessment should consider three categories of factors:

• Static risk factors (unchangeable historical factors): Previous suicide attempts (strongest predictor), past history of violence, age, gender (males complete suicide more frequently; females attempt more frequently), history of childhood abuse, previous psychiatric admissions, forensic history, family history of suicide
• Dynamic risk factors (current and changeable): Current mental state (hopelessness is the most significant psychological predictor of suicide), active substance misuse, recent stressors (bereavement, relationship breakdown, job loss, financial crisis, legal problems), non-adherence with treatment, command hallucinations, social isolation, insomnia, recent discharge from psychiatric hospital (highest risk period is first 2 weeks post-discharge)
• Protective factors: Strong social support network, dependent children (particularly for mothers), religious or cultural beliefs against suicide, positive therapeutic relationship, active engagement with services, employment, future plans and goals, good coping strategies, reasons for living

The balance between these factors informs your overall risk formulation.

Suicide Risk Assessment

Key Areas to Cover

1. Ideation: "Have you had any thoughts that life isn't worth living?" / "Have you wished you could go to sleep and not wake up?"
2. Intent: "Have you thought about acting on these thoughts?" / "How strong is the urge to act on these feelings?"
3. Plan: "Have you made any specific plans about how you would end your life?"
4. Means: "Do you have access to means of harming yourself?" — ask specifically about medications stockpiled, sharps, ligature points, access to heights, firearms (rare in UK but important internationally)
5. Preparatory acts: Writing letters or notes, giving away possessions, putting affairs in order, researching methods, visiting significant places as a form of goodbye, making a will
6. Previous attempts: Number, methods, severity, medical lethency, circumstances (was it planned or impulsive?), was the person found or did they seek help?, subjective intent at the time, feelings afterwards (relief at surviving or regret?)
7. Timeframe: "When did these thoughts start?" / "How frequently do they occur?" / "When was the last time you had these thoughts?"
8. Hopelessness: This is the cognitive factor most closely associated with completed suicide. Assess directly: "Do you feel hopeless about the future?" / "Can you see things getting better?"
9. Protective factors: Reasons for living, social support, future plans, dependent children, religious beliefs, fear of death or pain

The SAD PERSONS Mnemonic

While not a validated clinical tool, the SAD PERSONS mnemonic is useful for ensuring you have covered key risk factors:

• S — Sex (male)
• A — Age (older adults, young males)
• D — Depression (or other mental illness)
• P — Previous attempt
• E — Ethanol/substance abuse
• R — Rational thinking loss (psychosis)
• S — Social support lacking
• O — Organised plan
• N — No spouse/partner
• S — Sickness (chronic physical illness)

Transitioning Into Sensitive Risk Questions

A common mistake is abruptly switching to risk questions mid-conversation. Instead, use transitional phrases that link what the patient has told you to the risk domain you need to explore:

• "You've described feeling very low and hopeless. When people feel this way, they sometimes have thoughts about harming themselves or ending their life. Has anything like that crossed your mind?"
• "It sounds like things have been incredibly difficult recently. Have there been times when you've felt like you can't go on?"
• "You mentioned feeling like a burden to your family. Sometimes when people feel that way, they can have thoughts that others would be better off without them. Have you ever felt like that?"
• "I appreciate you sharing how angry you've been feeling. When people feel this level of frustration, they sometimes have thoughts about harming themselves or others. Is that something you've experienced?"

These transitions normalise the question and demonstrate empathy, which makes patients more likely to disclose.

Direct Questions When Needed

If you have reason to believe risk is present, do not avoid direct questions:

• "Have you thought about ending your life?"
• "Have you made a plan to kill yourself?"
• "Do you have access to the means to carry this out?"

Research consistently shows that asking about suicide does not plant the idea or increase risk. Examiners know this evidence and expect you to ask directly when clinically indicated.

Violence Risk Assessment

Violence risk assessment is frequently tested in CASC but often poorly handled by candidates. You may encounter this in stations involving psychosis, personality disorder, substance misuse, forensic scenarios, or angry/agitated patients.

Key Domains to Assess

History of violence (the strongest predictor of future violence): - Previous violent acts: nature, severity, frequency, targets, context, weapon use - Age at first violent act - Previous forensic history: arrests, charges, convictions, sentences - Violence in the context of mental illness vs. when well

Current risk indicators: - Active psychotic symptoms, particularly command hallucinations directing violence, persecutory delusions with an identified target, threat-control override symptoms (belief that external forces are controlling their actions) - Active substance misuse (particularly stimulants, alcohol intoxication) - Expressed intent to harm a specific person - Recent escalation in threatening behaviour - Access to weapons - Breakdown of social supports or accommodation - Non-adherence with treatment

Situational factors: - Identified victim or target - Proximity to potential victims - Lack of supervision or monitoring - Environmental stressors

Structured Professional Judgement Tools

In clinical practice, structured tools improve the accuracy of violence risk assessment. Be aware of these for CASC discussions:

• HCR-20 (Historical, Clinical, Risk Management-20): The most widely used structured professional judgement tool for violence risk. Covers 10 historical, 5 clinical, and 5 risk management items.
• START (Short-Term Assessment of Risk and Treatability): Assesses both risks and strengths across multiple domains.

Asking About Violence in CASC

Use similar transitional and normalising techniques: - "I'd like to ask about times when you've felt very angry or when things have got physical. Has that ever happened?" - "When you feel this frustrated, have you ever felt like lashing out or hurting someone?" - "Have you had any thoughts about harming the person you've been in conflict with?"

Self-Neglect Risk Assessment

Self-neglect is a commonly overlooked risk domain in CASC. It should be assessed particularly in stations involving depression, psychosis, dementia, substance misuse, and eating disorders.

Areas to Screen - **Nutrition and hydration**: "Are you eating and drinking regularly?" / "When did you last have a meal?" - **Personal hygiene**: Observable from appearance — note grooming, clothing, body odour (in your MSE observations) - **Living conditions**: "How are things at home? Is your home in a reasonable state?" - **Medication adherence**: "Are you taking your medications as prescribed?" - **Financial management**: "Are you managing to pay your bills and look after your finances?" - **Physical health neglect**: Failing to attend medical appointments, untreated physical conditions - **Social engagement**: Withdrawal from usual activities, isolation

Safeguarding Considerations

CASC stations may involve safeguarding concerns. Screen for:

• Children: Are there children in the household? Are they affected by the patient's illness? Any concerns about neglect, emotional abuse, or physical harm? Involvement of social services?
• Vulnerable adults: Is the patient vulnerable to exploitation, abuse, or neglect by others? Are they subject to coercion, financial exploitation, or domestic violence?
• Domestic abuse: "Do you feel safe at home?" / "Has anyone at home ever hurt you or threatened you?"

If safeguarding concerns arise, acknowledge them and state that you have a duty to escalate — this is what examiners expect.

Risk Formulation and Documentation

A good risk formulation goes beyond simply labelling risk as low, medium, or high. Examiners expect you to explain your reasoning:

Structure for a Risk Formulation

1. Identify the risk domain: suicide, self-harm, violence, self-neglect, vulnerability
2. Summarise the key factors: "The risk of suicide is elevated because of..." (current hopelessness, active plan with means, previous attempt, social isolation)
3. Note the protective factors: "Protective factors include..." (engagement with services, dependent children, no access to lethal means)
4. State your overall risk judgement with reasoning: "On balance, I would assess the risk of suicide as moderate to high in the short term, primarily driven by the combination of hopelessness, a specific plan, and the recent loss of his spouse"
5. Outline a management plan that addresses the modifiable risk factors

Key Principle Risk is not a static label — it changes over time and with circumstances. Demonstrate awareness that your assessment is a snapshot and that risk will need to be reviewed regularly.

Safety Planning

When risk is identified, examiners expect you to outline a proportionate safety plan. Elements include:

• Immediate safety: Does the patient need to be in a place of safety? Informal admission? Mental Health Act assessment?
• Reducing access to means: Can medications be reduced to weekly prescriptions? Can ligature points or weapons be removed from the home? Should firearms be surrendered?
• Increasing support: Crisis team referral, increased frequency of community follow-up, involving family or friends in safety planning
• Crisis plan: What should the patient do if they feel unable to keep themselves safe? Crisis line numbers, A&E attendance, contacting their care coordinator
• Treatment optimisation: Is the current treatment adequate? Does medication need adjustment? Does psychological therapy need to be expedited?
• Follow-up: When will you next review the patient? How will ongoing risk be monitored?

Common Pitfalls

1. Asking risk questions in a checklist manner — Weave them into the conversation using transitional phrases and follow up on positive responses
2. Not asking about means — This is crucial for safety planning and frequently missed; examiners specifically look for it
3. Forgetting protective factors — Risk is a balance of risk and protective factors; listing only risk factors without protective factors suggests a one-dimensional assessment
4. Not formulating a management plan — Risk assessment without a plan is incomplete and will cost you marks; always close with next steps
5. Being afraid to ask direct questions — Research consistently confirms that asking about suicide does not increase risk
6. Only assessing suicide risk — Remember to consider violence, self-neglect, and vulnerability when clinically relevant
7. Failing to document clearly — Even in CASC, demonstrate that you would document your risk assessment systematically
8. Ignoring the timeframe — Risk is different over different periods; specify whether you are assessing immediate, short-term, or longer-term risk
9. Not involving the patient in safety planning — Collaborative safety planning is more effective than clinician-imposed plans
