THE COMPETENT CANDIDATE

The competent candidate should be able to:


Q1: What are the key differential diagnoses for Michael’s presentation?

A structured approach is required to differentiate between substance-induced symptoms and primary mental health conditions.

  • Substance-Induced Disorders (Most Likely):
    • Methamphetamine intoxicationAgitation, paranoia, tachycardia, hypervigilance, pressured speech.
    • Methamphetamine withdrawalFatigue, depression, irritability, anhedonia, cravings.
    • Substance-induced psychosisParanoia, hallucinations, disorganised thinking, often resolves after drug clearance.
  • Primary Psychiatric Disorders (Must Consider):
    • Generalised Anxiety Disorder (GAD) – Pre-existing in Michael, can be worsened by stimulant use.
    • Major Depressive Disorder – If symptoms persist beyond withdrawal.
    • Bipolar Disorder – If mood instability and impulsivity predate substance use.
    • Schizophrenia – Persistent delusions or hallucinations despite abstinence.
  • Medical Causes (Red Flags):
    • Cardiac arrhythmias or hypertension – Methamphetamine-related cardiotoxicity.
    • Hepatitis B or C – High-risk drug use.
    • Neurological conditions – If persistent cognitive symptoms post-abstinence.

A competent candidate prioritises substance-related effects while assessing for co-existing psychiatric or medical conditions.


Q2: What further history and investigations would be useful in this case?

  • Further History:
    • Pattern of drug use: Frequency, amount, route, attempts to quit, cravings.
    • Withdrawal symptoms: Severity, past withdrawal experiences, overdose history.
    • Mental health history: Pre-existing depression, anxiety, suicidal thoughts.
    • Social and legal concerns: Housing, employment, legal issues, support systems.
  • Investigations:
    • Urine drug screen – Confirms recent methamphetamine and benzodiazepine use.
    • Liver function tests (LFTs) – Assess for alcohol or drug-related liver damage.
    • Hepatitis B, C, HIV screening – Due to past IV drug use.
    • ECG – If hypertensive, tachycardic, or at risk of arrhythmias.

A competent candidate tailors investigations to assess acute and long-term risks.


Q3: How would you engage Michael in a conversation about his drug use and readiness for change?

  1. Build rapport and validate concerns:
    • “I appreciate you coming in today—it’s not easy to talk about drug use.”
  2. Use motivational interviewing techniques:
    • Open-ended questions: “What concerns do you have about your methamphetamine use?”
    • Assess readiness: “On a scale of 1-10, how ready are you to make a change?”
    • Explore pros and cons: “What do you enjoy about using? What don’t you like?”
  3. Harm minimisation approach:
    • Safer drug use: Avoid IV use, use clean needles, hydrate, eat well.
    • Recognising overdose signs: Chest pain, severe paranoia, confusion.
    • Link to needle exchange programs if applicable.
  4. Discuss treatment options without pressure:
    • “If you decide to cut down, there are supports available, including medical and psychological help.”

A competent candidate avoids judgement, explores motivation, and promotes harm reduction.


Q4: Outline your initial management plan for Michael.

  1. Acute Symptom Management:
    • If agitated, consider short-term benzodiazepine (e.g., diazepam 2-5mg PRN).
    • If psychotic features, consider antipsychotic (e.g., olanzapine 2.5-5mg PRN).
    • Monitor for withdrawal symptoms, ensuring safety at home.
  2. Referral and Support Services:
    • Drug and Alcohol Counselling – Link to local addiction services.
    • Mental Health Support – Consider psychologist or GP Mental Health Treatment Plan.
    • Peer support programs – Encourage Narcotics Anonymous or SMART Recovery.
  3. Long-Term Management Plan:
    • Regular GP reviews – Monitor mental health, support change.
    • Consider pharmacotherapyN-acetylcysteine (NAC) may help cravings.
    • Crisis planning – Identify relapse triggers and emergency support options.

A competent candidate provides a structured, multidisciplinary approach focusing on safety and support.


Q5: What preventive health strategies should be implemented for Michael?

  1. Vaccination and Screening:
    • Hepatitis B vaccine if not immune.
    • STI screening, including HIV, syphilis, chlamydia, gonorrhoea.
  2. Lifestyle and General Health:
    • Smoking cessation supportNRT, varenicline, behavioural therapy.
    • Alcohol harm reduction – Encourage low-risk drinking strategies.
    • Nutrition and sleep hygiene – Essential for physical and mental recovery.
  3. Regular Mental Health Check-Ins:
    • Screening for depression, anxiety, PTSD.
    • Crisis planning – Identify support services for relapse prevention.

A competent candidate integrates physical and mental health prevention strategies into long-term care.


SUMMARY OF A COMPETENT ANSWER

  • Recognises substance-induced vs primary psychiatric conditions, prioritising withdrawal and psychosis risk.
  • Takes a structured history, covering drug use pattern, mental health, social risk factors.
  • Orders targeted investigations, including urine drug screen, LFTs, hepatitis serology.
  • Uses motivational interviewing, engaging without judgement while promoting harm minimisation.
  • Implements an evidence-based management plan, with mental health support, addiction referrals, and medication if required.
  • Integrates preventive care, including vaccination, STI screening, and lifestyle modifications.

PITFALLS

  • Being judgemental or dismissive, which reduces engagement in care.
  • Failing to screen for medical complications, such as hepatitis C or cardiovascular risks.
  • Not considering harm minimisation, missing an opportunity to reduce overdose and transmission risks.
  • Neglecting long-term mental health support, leading to poor relapse prevention.
  • Over-relying on pharmacotherapy, without addressing psychosocial interventions.
