EVENT: Evidence-based shared decision-making assistant for antipsychotics



The project is funded by the Innovation Fund of the German Federal Government (funding code: 01VSF19022). More information here.

Selecting the appropriate antipsychotic is a crucial medical decision in the treatment of schizophrenia. This decision requires not only careful risk-benefit assessments of different medications but also consideration of the preferences and values of the individual patient. Although well-established information exists regarding the efficacy and side-effect profiles of antipsychotics, there is no framework that combines medical evidence on antipsychotics with patient preferences and values within a shared decision-making process.

To address this gap, we have developed an evidence-based tool called the Shared-Decision-Making Assistant (SDM-assistant) for selecting antipsychotics. This tool supports shared decision-making by providing and visualizing information about the efficacy and side effects of different antipsychotics, based on high-quality network meta-analysis.

We are currently conducting a cluster-randomized trial comparing the use of the SDM-assistant with treatment as usual in hospitalized patients with schizophrenia.

If successful, implementing the SDM-assistant could enhance evidence-based medicine in schizophrenia by incorporating patient preferences and values into treatment decisions, leading to improved patient involvement in decision-making and more effective treatment choices.

The protocol was registered a priori in the German Clinical Trial Register (ID: DRKS00027316) and published in BMC Psychiatry:
