A 32-year-old woman with a 5-year history of schizophrenia, currently on olanzapine 15 mg daily, presents with persistent auditory hallucinations, delusions of reference, and poor medication adherence. Her family reports she stopped taking medication 2 months ago. She denies suicidal or homicidal ideation. Mental status examination confirms active psychotic symptoms. What is the most appropriate next step in management?

Explanation

## Management of Relapse Due to Non-Adherence in Schizophrenia **Key Point:** A patient with established schizophrenia who relapses due to medication non-adherence requires inpatient stabilization, assessment of treatment response, and consideration of long-acting injectable (LAI) antipsychotics to prevent future non-adherence. ### Decision-Making Algorithm ```mermaid flowchart TD A[Schizophrenia relapse due to non-adherence]:::outcome --> B{Active psychosis?}:::decision B -->|Yes| C{Suicidal/Homicidal risk?}:::decision C -->|Yes| D[Admit for safety]:::urgent C -->|No| E[Assess need for admission]:::decision E -->|Poor insight, non-adherence history| F[Admit for stabilization]:::action E -->|Good insight, supportive family| G[Intensive outpatient management]:::action F --> H[Restart/optimize current antipsychotic]:::action H --> I{Response after 4-6 weeks?}:::decision I -->|Yes| J[Plan LAI antipsychotic to improve adherence]:::action I -->|No| K[Consider clozapine or switch agent]:::action J --> L[Discharge with LAI, psychoeducation, family support]:::outcome ``` ### Why Admission Is Indicated | Factor | This Patient | Clinical Significance | | --- | --- | --- | | **Active psychosis** | Yes (hallucinations, delusions) | Requires inpatient assessment and stabilization | | **Non-adherence history** | Yes (stopped meds 2 months ago) | High risk of relapse; needs structured environment | | **Insight** | Poor (no mention of recognizing illness) | Unlikely to comply with outpatient regimen | | **Functional status** | Declining | Supports need for inpatient care | | **Safety risk** | Denies SI/HI but psychotic | Inpatient observation warranted | **High-Yield:** Non-adherence is the leading cause of relapse in schizophrenia. Inpatient admission allows: - Direct observation of medication administration - Assessment of treatment response and side effects - Evaluation for treatment resistance - Planning of adherence-enhancing interventions (LAI antipsychotics) ### Long-Acting Injectable (LAI) Antipsychotics **Clinical Pearl:** After stabilization on oral antipsychotics, LAI agents should be offered to patients with: - History of non-adherence - Multiple relapses - Poor insight - Chronic schizophrenia Common LAI options: - Paliperidone palmitate (monthly or 3-monthly) - Fluphenazine decanoate (fortnightly) - Haloperidol decanoate (monthly) **Mnemonic: LAIN** — **L**ong-acting **A**ntipsychotics **I**mprove **N**on-adherence ### Why NOT Increase Olanzapine? The problem is not inadequate dosing—it is non-adherence. Increasing the dose of a medication the patient is not taking will not improve outcomes. The focus must shift to adherence strategies. **Warning:** Do NOT confuse "poor response" (medication not working) with "poor adherence" (patient not taking medication). This patient has relapsed due to stopping medication, not due to treatment resistance.
