What this trial studies

This study aims to evaluate the feasibility of administering open-label placebos to patients experiencing non-specific acute pain in the emergency department. Patients will be randomized into two groups: one receiving open-label placebo tablets and the other receiving standard treatment with ibuprofen. The study will assess the outcomes over a duration of 30 days, focusing on the effectiveness and patient response to the open-label placebo intervention. This collaborative effort involves the Emergency Department and the Faculty of Psychology at the University of Basel.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older with a diagnosis of non-specific acute pain who can understand the study and provide informed consent.

Not a fit: Patients with chronic pain or those requiring hospitalization will not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could provide an effective and low-cost alternative for managing non-specific pain in emergency settings.

How similar studies have performed: While the use of open-label placebos is a novel approach in emergency settings, similar studies have shown promising results in other contexts.
