What this trial studies

This study investigates the impact of weighted blankets on anxiety and postsurgical pain in patients undergoing breast surgery. It aims to determine if the weight of the blanket can influence pre-surgical anxiety levels and subsequent pain after surgery. Participants will use a weighted blanket for up to three months and provide feedback through a smartphone app. The study will also explore psychological and clinical factors that may affect individual responses to the blanket's weight.

Who should consider this trial

Good fit: Ideal candidates are English-speaking individuals scheduled for breast surgery who are willing to use a weighted blanket.

Not a fit: Patients who are pregnant, have chronic high-dose opioid use, or have previously used a weighted blanket may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could help reduce postsurgical pain and anxiety for patients undergoing breast surgery.

How similar studies have performed: While the specific use of weighted blankets in this context is novel, other studies have shown that anxiety management can positively influence pain outcomes.
