When the patient isn't improving as expected, the right response is rarely to escalate within the current framework. The right response is to reopen the case — question the diagnosis, verify the assumptions, reformulate the picture, consider what hasn't been tried, and engage the patient honestly about the situation.
Question the diagnosis. The most common cause of treatment failure in psychiatry is a wrong or incomplete diagnosis. The patient with "treatment-resistant depression" who is actually bipolar. The patient with "anxiety" who has untreated OSA. The patient with "schizophrenia" who has autoimmune encephalitis. The patient with "personality disorder" who has trauma-related symptoms that haven't been addressed. Reopen the differential at decision points.
Verify adherence. The "failed trial" may have been adequate dose taken as prescribed; it may have been adequate dose taken inconsistently; it may have been low dose. The patient who endorses adherence may be selectively adherent. Ask specifically and non-judgmentally about specific patterns.
Examine adequacy of prior trials. Each prior medication: dose, duration, response. Many "failed trials" turn out to have been inadequate — sub-therapeutic dose, too short duration, side effect-limited rather than efficacy-limited. Inadequate trials are not failed trials.
Reformulate. What's the underlying problem now? Has something changed in the patient's life that's making the current approach insufficient? Is there a comorbidity that hasn't been addressed (substance use, medical illness, ongoing trauma)? Are there social factors (housing, relationships, finances) that need attention before pharmacotherapy will work?
Consider what hasn't been tried. Different mechanism class. Augmentation strategies. Psychotherapy if not yet engaged. ECT, TMS, esketamine for treatment-resistant depression. Family work. Lifestyle interventions. Often the patient has been treated narrowly when a broader approach is what's needed.
Engage the patient honestly. "I want to step back. We've been at this for months and I don't think we're where you want to be. Let me think about it differently. Would you be open to a consultation, or to considering something we haven't tried?" Patients usually appreciate the honesty; pretending continued progress when there isn't any damages trust.
Refer when needed. Specialty consultation. ECT or TMS centers. Specialty programs for treatment-resistant illness. The clinician who knows when to refer serves patients better than the clinician who persists with insufficient tools.
