Customized Adherence Enhancement Plus Long-acting Injectable Antipsychotic

Summary

Psychotropic medications are a cornerstone of treatment for individuals with schizophrenia and schizoaffective disorder, however rates of full or partial non-adherence can exceed 60%. Inadequate adherence is associated with poor outcomes such as relapse, homelessness, hospitalization, and increased health care costs. Studies have shown a direct correlation between non-adherence and rates of relapse in schizophrenia; on average, non-adherent patients have a risk of relapse that is 3.7 times greater than their adherent counterparts. A major obstacle to good outcomes in the maintenance treatment of patients with severe mental illness is difficulty with medication routines on an on-going basis. For this reason, long-acting injectable antipsychotic medication is a particularly attractive treatment option for populations with schizophrenia and schizoaffective disorder, although it is unlikely that medication treatment alone is likely to modify long-term attitudes and behaviors.

This prospective study is a pilot analysis of a combined approach which merges a psychosocial intervention to optimize treatment attitudes towards psychotropic medication (CAE) and long-acting injectable antipsychotic medication (L) in recently homeless individuals with schizophrenia or schizoaffective disorder who are known to have on-going difficulties with treatment non-adherence. It is expected that this combined approach (CAE-L) will improve illness outcomes among the most vulnerable of populations with schizophrenia or schizoaffective disorder.

Conditions

• Patient Noncompliance

Interventions

DRUG

haloperidol decanoate

Drug is in in injectable form and will be administered approximately every four weeks through Week 25 of the study. A participant may continue on the drug after Week 25 at the discretion of his or her treating psychiatrist. Dosage is per package insert or at the discretion of the psychiatrist.

DRUG

haloperidol

Drug will be administered in oral form to participants not already taking oral haloperidol and then transitioned to the injectable version. Dosage and frequency is at the discretion of the psychiatrist.

BEHAVIORAL

Customized Adherence Enhancement

CAE targets key areas relevant to non-adherent populations with schizophrenia or schizoaffective disorder: 1) inadequate or incorrect understanding of mental disorder; 2) lack of medication-taking routines; 3) poor communication with care providers; and 4) substance use which interferes with adherence and healthy behaviors that promote recovery. CAE is delivered based upon initial assessment of reasons for non-adherence and only those components of CAE that are determined to be indicated for that individual are delivered (psychoeducation, modified motivational interviewing, assistance with medication routines, coaching in communication with providers).
