Patient-Centered Medication Adherence Intervention for Schizophrenia

Study Summary

Efficacious antipsychotic medication treatments for schizophrenia are available; however , antipsychotic regimens frequently do not achieve their potential because of poor medication adherence. To date, medication adherence interventions have not been widely adopted or sustained in "real-world" practice settings. One reason for this is the substantial resource investment necessary to implement and sustain available interventions. In response to these problems, we developed a patient-centered adherence intervention based on patient-identified barriers, facilitators, and motivators (BFMs) for medication adherence. The intervention includes a BFM survey (checklist and preference weighting exercise to determine the patient's most important BFM) and a brief list of adherence enhancing suggestions (Options List) tailored to the patient-identified BFMs and compatible with CPRS. The long-term objective of this proposed research is to improve antipsychotic medication adherence and clinical outcomes for patients with schizophrenia using a cost-effective medication adherence intervention. The short-term objectives are to refine and test a patient-centered medication adherence intervention for VA patients with schizophrenia and specifically to: 1. Enhance the feasibility and acceptability of the BFM intervention by reducing the burden on patients and mental health providers through BFM checklist item reduction, provider intervention input, and patient intervention input. We hypothesize that our use of end-user input will result in at least 80% of intervention patients having documentation of a BFM intervention in CPRS. 2. Compare the effects of the BFM intervention versus usual care on changes in medication adherence and schizophrenia symptom severity. We hypothesize that the intervention will result in a) greater medication adherence and b) lower schizophrenia symptom severity than usual care. 3. Exploratory objective: compare the effects of the BFM intervention versus usual c

Primary Outcome

The self-report adherence measure asked patients to think about the past four weeks and report to what extent they took their medication for mental, emotional, or nervous problems and report the result on a 5-point Likert scale ranging from 'I never missed taking my medicine' to 'I stopped taking the medicine altogether'. Patients who received depot injections were asked to think about the past six months. Self-report adherence was defined as 1=I never missed taking my medicine' and 0=any other
