Difficulty: MediumAnxiety, OCD, and Trauma-Related Disorders

A 21-year-old man is brought to the outpatient psychiatric clinic by his mother. For the past 3 weeks, he has been spending up to 6 hours a day repeatedly checking locks, counting backwards from 100, and washing his hands. He states he must perform these actions because he is tormented by intrusive, unwanted thoughts that his family will die in a house fire if he does not. He recognizes that these thoughts are irrational but feels immense, paralyzing anxiety if he attempts to stop the behaviors. His psychiatric history is notable for a hospitalization at age 19 for a 2-week episode characterized by a decreased need for sleep, grandiosity, and pressured speech, which was preceded by a major depressive episode. He is currently unmedicated. At the end of the clinical assessment, the patient explicitly requests that his medical information remain private. His mother, however, demands to be informed of the diagnosis and treatment plan, stating she has a right to know because he lives in her home and is covered under her health insurance. Which of the following is the most appropriate next step in the management of this patient?

  1. Initiate exposure and response prevention therapy and maintain patient confidentiality.Answer
  2. B
    Initiate fluoxetine monotherapy and maintain patient confidentiality.
  3. C
    Diagnose schizophreniform disorder and initiate a second-generation antipsychotic.
  4. D
    Initiate clomipramine and phenelzine to rapidly control symptoms.
  5. E
    Initiate exposure and response prevention therapy and disclose the treatment plan to his mother.

Answer

The most appropriate step is to initiate exposure and response prevention therapy while honoring the patient's request to maintain medical confidentiality.
The correct answer addresses both the optimal management of Obsessive-Compulsive Disorder (OCD) in a complex psychiatric context and the ethical imperative of patient privacy. The patient's intrusive thoughts and compensatory repetitive behaviors confirm a diagnosis of OCD. While selective serotonin reuptake inhibitors (SSRIs) are a typical first-line pharmacotherapy for OCD, this patient has a clear history of Bipolar I disorder (evidenced by a prior manic episode requiring hospitalization). SSRI monotherapy in patients with bipolar disorder carries a significant risk of precipitating a manic switch. Therefore, Exposure and Response Prevention (ERP) therapy, a specialized form of cognitive-behavioral therapy, is the safest and most effective first-line monotherapy for his OCD. Additionally, competent adult patients have a fundamental right to medical confidentiality. Provision of housing or health insurance by a parent does not grant legal access to protected health information. The physician must respect the patient's explicit request for privacy.

Step-by-Step Solution

1
Identify the primary acute psychiatric diagnosis.
The patient has Obsessive-Compulsive Disorder (OCD).
The presence of time-consuming, distressing intrusive thoughts (obsessions) and compensatory repetitive behaviors (compulsions) with preserved insight confirms OCD.
2
Evaluate the patient's psychiatric history for comorbidities.
The patient has an underlying diagnosis of Bipolar I disorder.
The history of a 2-week episode of grandiosity, decreased sleep, and pressured speech requiring hospitalization meets the criteria for a manic episode.
3
Determine the safest initial management strategy for OCD in this context.
Select Exposure and Response Prevention (ERP) therapy.
Standard first-line pharmacotherapy for OCD (SSRI monotherapy) is contraindicated in Bipolar I disorder due to the risk of inducing mania. ERP is a highly effective, non-pharmacologic first-line treatment that carries no risk of manic switch.
4
Apply core ethical principles regarding patient privacy.
Refuse the mother's request for disclosure.
A competent 21-year-old adult holds the fundamental right to medical confidentiality, which is not negated by parental financial support, shared housing, or dependent insurance coverage.

Key Concept

Management of OCD in patients with comorbid Bipolar I disorder requires avoiding SSRI monotherapy to prevent manic switch, making Exposure and Response Prevention (ERP) therapy the safest first-line intervention. Competent adult patients retain the right to confidentiality regardless of financial dependence.
