A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

Researchers will collect patient views through a questionnaire to understand which medication side effects are least acceptable given the benefits in pain relief. The effort focuses on adults with chronic pain who are currently receiving treatment and can understand French or English. The study uses a patient-reported approach to help guide future treatment options. No biological interventions are involved beyond the survey, and responses will inform preference-based considerations in pain management. The lead site is Université Catholique de Louvain in Brussels, with no listed collaborators.

Why it matters

Potential benefit: If successful, results could inform clinicians and researchers about patient-prioritized trade-offs between side effects and pain relief to improve future treatments.

How similar studies have gone: Similar poster surveys have been used to elicit patient preferences in other therapeutic areas; the direct impact on treatment choices in pain management remains exploratory.
