What this trial studies

This observational study aims to develop and evaluate the PRoSIT tool, which identifies potentially dangerous drug interactions in hospital discharge prescriptions for patients aged 65 and older. The study is structured in three phases: first, the development of the PRoSIT tool and interface; second, the evaluation of its performance against expert opinions; and third, the assessment of its impact on care organization at Bordeaux University Hospital. By utilizing hospital data warehouses, the study seeks to provide real-time feedback to prescribers to reduce the frequency of harmful co-prescriptions.

Who should consider this trial

Good fit: Ideal candidates for this study are patients aged 65 years or older who are hospitalized or seen in consultations in cardiology, internal medicine, or neurology departments.

Not a fit: Patients under 65 years of age or those not receiving care in the specified departments may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could significantly reduce the prevalence of iatrogenic diseases caused by harmful drug interactions in elderly patients.

How similar studies have performed: Other studies have shown success in identifying drug interactions using similar approaches, but this specific application in a hospital setting is relatively novel.
