SCENARIO

John Mitchell, a 34-year-old Australian soldier, has recently returned from a nine-month deployment in Afghanistan. He presents to your general practice with a range of troubling symptoms. He reports experiencing frequent nightmares and flashbacks related to traumatic events during his service. John describes feeling constantly on edge, jumpy, and unable to relax, especially in crowded or noisy environments.

He also reports being irritable, having difficulty concentrating, and experiencing memory lapses, which have started to affect his performance at work as a truck driver. He has begun avoiding social situations and crowded places, including the supermarket and gatherings with friends, due to feelings of anxiety and panic.

John admits to using alcohol to “calm his nerves” and help him sleep, consuming approximately 6-8 standard drinks each evening. He has noticed that his sleep is still disturbed, waking frequently with sweats and a racing heart. He has also started experiencing frequent tension headaches and feels tired and fatigued during the day. His symptoms have significantly impacted his relationships, work, and overall quality of life.

THE COMPETENT CANDIDATE

The competent candidate should be able to:

Q1: What are the key elements in taking a history from this patient?

A competent candidate will begin by establishing a rapport with John, using empathetic and non-judgmental communication. This is crucial to making the patient feel safe and comfortable, given the sensitive nature of his symptoms related to PTSD.

Key elements to cover in the history include:

  • Symptoms of PTSD: Ask about the frequency, severity, and triggers for his nightmares, flashbacks, hypervigilance, and avoidance behaviours. Clarify how these symptoms impact his daily life, including work, social activities, and relationships.
  • Mental Health History: Explore past mental health issues, including previous diagnoses of depression, and any treatments or therapies received. Determine if there have been any recent changes or escalation in symptoms.
  • Substance Use: Detailed inquiry into his alcohol consumption, including the amount, frequency, and any negative impacts (e.g., on sleep, mood, or functioning). Screen for other substances, such as illicit drugs or misuse of prescription medication.
  • Psychosocial Factors: Explore his social support network, relationships, employment challenges, financial stress, and any legal or social concerns. Ask about coping strategies and whether he feels at risk of self-harm or harm to others.
  • Physical Symptoms: Review his recent headaches, sleep disturbances, and other somatic complaints. Screen for symptoms that might suggest other mental health disorders, such as anxiety or mood disorders.
  • Military Experience: Gather details about his deployment to Afghanistan, particularly any specific traumatic events or stressors that might contribute to PTSD symptoms.

Throughout the history-taking, use open-ended questions to encourage detailed responses, actively listen, and show empathy to build trust. Tailor questions based on responses and remain alert to cues indicating distress or reluctance to disclose sensitive information.

Q2: What is your differential diagnosis for this patient?

A competent candidate should present a differential diagnosis that considers both psychological and medical conditions:

  • Post-Traumatic Stress Disorder (PTSD): The primary consideration given John’s history of trauma exposure, nightmares, flashbacks, hypervigilance, and avoidance behaviours.
  • Major Depressive Disorder (MDD): Symptoms like irritability, poor concentration, and feelings of disconnection may overlap with depression.
  • Alcohol Use Disorder: Given his high alcohol consumption, consider this as a comorbid condition or a primary diagnosis contributing to mood and sleep disturbances.
  • Generalized Anxiety Disorder (GAD): Symptoms such as restlessness, fatigue, difficulty concentrating, and muscle tension could align with GAD.
  • Adjustment Disorder: Consider if the symptoms are a reaction to his recent life transition from military service to civilian life.
  • Sleep Disorder: Evaluate for primary or secondary insomnia due to PTSD or alcohol use.
  • Traumatic Brain Injury (TBI): Given his military history, consider this if there are any neurological symptoms like memory loss or concentration difficulties.
  • Organic: intracerebral, metabolic, endocrine, drug-induced

Highlight that PTSD is the leading diagnosis, but other comorbidities or differentials should not be overlooked. Justify each diagnosis based on clinical findings and history.

Q3: Outline your management plan for John.

A competent candidate should formulate a management plan that addresses both immediate and long-term needs:

  1. Immediate Safety and Risk Assessment:
    • Conduct a thorough risk assessment for suicide, self-harm, or harm to others.
    • Discuss options for urgent mental health support, including referral to a psychologist or psychiatrist and involving crisis teams if needed.
  2. Non-Pharmacological Interventions:
    • Recommend evidence-based psychological therapies, such as trauma-focused Cognitive Behavioural Therapy (CBT) or Eye Movement Desensitization and Reprocessing (EMDR).
    • Discuss alcohol reduction strategies, provide information on local addiction support services, and consider referral for specialist addiction services.
  3. Pharmacological Management:
    • Consider starting selective serotonin reuptake inhibitors (SSRIs), like sertraline or paroxetine, which are first-line pharmacological treatments for PTSD.
    • Evaluate the need for adjunct medications, such as prazosin for nightmares, or consider a short-term prescription of sleep aids if indicated, with caution.
  4. Follow-up and Ongoing Monitoring:
    • Schedule regular follow-ups to assess treatment response, medication adherence, and monitor for side effects or deterioration.
    • Develop a safety plan, including a list of emergency contacts and services.
  5. Referral and Collaboration:
    • Coordinate with mental health services, social workers, and veteran support organizations for holistic care.
    • Consider referral to a psychiatrist for medication management or complex PTSD cases.

Q4: How would you discuss PTSD and its management with the patient?

A competent candidate should aim for clear, empathetic communication to explain PTSD:

  1. Explain the Diagnosis:
    • Describe PTSD as a common and treatable condition resulting from trauma. Use simple language to explain how John’s experiences in Afghanistan may have triggered his symptoms.
    • Emphasize that his symptoms, such as nightmares, flashbacks, and avoidance, are normal responses to abnormal events.
  2. Outline the Management Plan:
    • Discuss both non-pharmacological (e.g., CBT, EMDR) and pharmacological options (e.g., SSRIs).
    • Emphasize the importance of gradual engagement with therapy and setting realistic goals.
  3. Address Concerns and Encourage Participation:
    • Address potential fears or misconceptions about mental health treatment, including concerns about medication or therapy.
    • Encourage John to view treatment as a collaborative process, where his input and comfort with different treatment options are valued.
  4. Provide Written and Verbal Resources:
    • Provide pamphlets or websites with information about PTSD and its management, including local support groups and services for veterans.

Q5: What are the risks and benefits of different therapeutic interventions for PTSD?

A competent candidate should compare therapeutic interventions:

  • Psychological Interventions:
    • Benefits: Effective for long-term management, no pharmacological side effects, builds coping skills.
    • Risks: Initial worsening of symptoms during exposure therapy requires regular attendance and engagement.
  • Pharmacological Interventions (SSRIs):
    • Benefits: It may reduce symptoms such as anxiety and depression and improve sleep.
    • Risks: Side effects (e.g., nausea, weight gain, sexual dysfunction), risk of withdrawal symptoms, especially in irregular takers.
  • Combined Approach:
    • Benefits: Potentially greater symptom reduction by addressing both physiological and psychological aspects.
    • Risks: Increased complexity in managing side effects and adherence.
  • Alternative Interventions (e.g., prazosin for nightmares):
    • Benefits: Targeted symptom relief.
    • Risks: Limited evidence, potential side effects like hypotension.
