Barriers and facilitators to antidepressant deprescribing - A qualitative interview study with general practitioners in Germany.

BACKGROUND

Long-term use of antidepressants frequently extends beyond clinical guidelines, with limited structured support for deprescribing in primary care. Little is known about the factors that influence general practitioners (GPs) in Germany regarding deprescribing of antidepressants.

OBJECTIVES

To identify barriers and facilitators that influence GPs in Germany regarding antidepressant deprescribing. To provide points of departure for developing a targeted intervention to address these challenges.

METHODS

We conducted semi-structured interviews with 20 GPs in Bavaria and purposively sampled for diversity in gender and professional experience. The interview topic guide was informed by the Capability-Opportunity-Motivation-Behaviour (COM-B) model and the Theoretical Domains Framework (TDF). Interviews were transcribed verbatim. Thematic analysis was conducted using a structured coding approach.

RESULTS

Key barriers to deprescribing included time constraints, limited practical tools, and inadequate collaboration with specialists, as well as uncertainty about when to deprescribe. Social and psychological factors, such as patient fears, were also significant. Facilitators included strong GP-patient communication, the use of digital tools, pharmacist support, and positive attitudes towards deprescribing.

CONCLUSION

Antidepressant deprescribing in German primary care is shaped by systemic, social, and behavioural factors. Addressing time constraints, enhancing interdisciplinary collaboration, and integrating decision-support tools into clinical practice could facilitate deprescribing. These insights inform targeted interventions to promote safe and evidence-based antidepressant use. Further research is recommended to develop an intervention suitable for real-world usage.
