Abstract

DECIDE Study

Effectiveness of shared decision making in treatment planning at discharge of inpatient with schizophrenia: interim analysis.

Introduction

Shared decision-making denotes a structured process that encourages full participation by patient and provider in making complex medical decisions. Hamann et al. conducted a few years ago a randomized controlled trial with schizophrenic inpatients and found increased knowledge and perceived involvement in decisions about antipsychotic treatment at discharge by the experimental group, but not clear beneficial effects on long term outcomes. The present communication introduces the DECIDE study.

Aims and objectives

Of the study: to demonstrate the effectiveness, measured as treatment adherence and readmissions at 3, 6 and 12 months, of shared decision making in the choice of antipsychotic treatment at discharge in a simple of schizophrenics hospitalized after an acute episode of their disorder. Of the oral presentation: to present preliminary conclusions with more of the half of the sample.

Methods

Randomized controlled trial, prospective, two parallel groups, not masked, comparing two interventions (shared decision making and treatment as usual). Study population: inpatients diagnosed of schizophrenia and schizoaffective disorders (ICD-10/DSM-IV-R: F20 y F25) at Adult Acute Hospitalization Unit at Jerez General Hospital.

Results

At discharge, increased scale score COMRADE, both subscales (Satisfacción in communication and trust in the decision) statistically significant. At 3 months follow-up, intensification of these differences in effect size and statistical significance and shows trends in health outcomes. We will present results for 6 and 12 months.
