How should I manage a patient with OCD and PTSD who, after sertraline titration to 200 mg and discussion of augmentation with lamotrigine or lurasidone, requests transfer of medication management to her primary‑care provider?

How to Proceed After Patient Requests Transfer of Care

Respect the patient's autonomy and facilitate a smooth transition to her primary care provider—this is the appropriate clinical and ethical response. The patient has clearly communicated her decision, and attempting to retain her in your care would be counterproductive and potentially harmful to the therapeutic relationship.

Understanding What Likely Happened

Your clinical approach was evidence-based but may have been experienced as overwhelming:

• Sertraline 200 mg daily is appropriate: Guidelines support 8-12 weeks at maximum tolerated doses for OCD 1, and doses up to 200 mg/day are FDA-approved 2. Higher doses (250-400 mg/day) show additional benefit in non-responders 3, though you hadn't reached that point yet.

• The augmentation discussion was premature: You proposed lamotrigine or lurasidone augmentation before completing the 12-week trial at 200 mg. While both agents have evidence in treatment-resistant OCD 1, 4, discussing augmentation before assessing full response to dose optimization likely created anxiety about treatment complexity.

• Diagnostic re-evaluation created uncertainty: Telling her she "didn't meet criteria for OCD anymore" after she presented with that diagnosis may have been confusing rather than reassuring, even if clinically accurate. This diagnostic shift, combined with PTSD symptoms and "borderline symptoms," likely felt destabilizing.

• Boundary issues with the therapist: The therapist's feedback that you were "stepping into her therapy territory" suggests you may have been providing detailed psychotherapy recommendations (DBT, other interventions) that overlapped with her ongoing therapy work.

Immediate Actions

Send a brief, professional response within 24-48 hours:

• Thank her for communicating her decision directly
• Acknowledge her autonomy in choosing her care team
• Offer to provide records and a brief summary to her PCP
• Leave the door open without pressure: "If you wish to return to psychiatric care in the future, I'm available"
• Do NOT attempt to convince her to stay or ask what went wrong

Coordinate the transition:

• Contact her PCP (with appropriate consent) to provide:
  • Current medication: sertraline 200 mg daily
  • Duration at current dose and response status
  • Any side effects or concerns
  • Recommendation to continue current dose for the full 12-week trial before considering changes
  • Note about PTSD symptoms (sertraline is also first-line for PTSD per VA/DoD guidelines 5)

Clinical Reflection Points

What went wrong (likely):

1. Pacing: You moved too quickly from dose optimization → diagnostic re-evaluation → augmentation discussion. Each of these is a significant clinical decision that needed more time to process.

2. Information overload: Spending an hour "diving into symptoms," providing extensive psychoeducation on DBT and multiple interventions, and discussing complex augmentation strategies (lamotrigine vs. lurasidone) in separate appointments created cognitive and emotional burden.

3. Role confusion: Providing detailed therapy recommendations while she had an active therapist created splitting and confusion about who was managing what aspects of care.

4. Premature complexity: Discussing borderline personality features and multiple augmentation agents before completing a straightforward SSRI optimization trial suggested the treatment would become increasingly complex.

Key Lessons for Future Practice

Slow down the pace of clinical decision-making:

• Complete one intervention fully before introducing the next
• Allow 12 weeks at maximum dose before discussing augmentation 1
• Space out major discussions (diagnosis, prognosis, next steps) across multiple visits

Maintain clear boundaries with therapists:

• Coordinate care but don't provide specific therapy modality recommendations
• Your role: medication management, safety assessment, diagnostic clarification
• Therapist's role: psychotherapy modality selection and implementation
• Communicate: "I support the work you're doing in therapy" rather than suggesting specific techniques

Simplify communication:

• Present one clear treatment plan at a time
• Avoid discussing multiple "next step" options simultaneously
• Frame dose increases as "optimizing current treatment" rather than introducing complexity

Recognize when "good care" feels overwhelming:

• Thorough assessment is valuable, but an hour-long deep dive in a second appointment may feel intense
• Some patients prefer incremental relationship-building over immediate depth
• High engagement can paradoxically create pressure to "match" the clinician's intensity

Common Pitfalls to Avoid

• Don't take it personally: This is about fit and pacing, not your clinical competence
• Don't pursue the patient: Respect her decision without attempting to "win her back"
• Don't blame the therapist: The boundary issue was a systems problem, not a personal conflict
• Don't abandon reflection: Use this as learning without excessive self-criticism

The patient's decision to transfer care is valid and should be honored promptly and professionally. Your clinical approach was evidence-based but the pacing and intensity didn't match her needs. This is valuable feedback for calibrating future patient interactions, particularly in early treatment phases.
