ClinConnect Summary

This clinical trial is studying how the quality of sleep before and after surgery affects the development of long-term pain in patients who have had surgery. Specifically, it looks at adults aged 18 to 80 who are scheduled for certain types of surgeries, like video-assisted thoracic surgery, modified radical mastectomy, or coronary artery bypass grafting. The researchers want to find out if poor sleep during this time makes it more likely for patients to experience chronic pain three months after their surgery.

If you or a family member are eligible to participate, you would wear a device that tracks your sleep patterns in the hospital and fill out questionnaires about your sleep and pain both before and after the surgery. This study will also follow up with participants at one, three, and six months after surgery to check on pain levels and overall quality of life. It’s important to know that not everyone can participate; for example, those who have had surgery recently or have certain medical conditions may be excluded.
