What this trial studies

This study focuses on frail and pre-frail elderly individuals over 65 years old who are scheduled for elective non-cardiac surgery requiring general anesthesia. It aims to assess the effectiveness of non-pharmacological interventions implemented by nursing teams to prevent postoperative delirium (POD) compared to traditional care. Participants will undergo various assessments, including frailty and cognitive tests, before being randomized into intervention and control groups. The intervention group will receive specific non-pharmacological care aimed at enhancing their orientation and comfort during the surgical process.

Why it matters

Potential benefit: If successful, this approach could significantly reduce the incidence of postoperative delirium in frail elderly patients, improving their recovery and overall outcomes.

How similar studies have gone: Other studies have shown promise in using non-pharmacological interventions to prevent delirium in elderly patients, suggesting this approach may be effective.
