Current Research Interests

(Disclosure: Dr. Carroll has delivered promotional talks for Lilly, and his research is supported in part by a gift from Allergan.)

Factors causing prolonged post-surgical pain and prolonged opioid use.

Some patients following routine surgery will experience chronic pain, and/or prolonged opioid use. This research done at Stanford Hospital and the Palo Alto VA Hospital will identify factors that delay pain resolution and opioid cessation in patients following surgery. Data collection is currently ongoing in the pilot stage, without funding. This clinical study offers abundant opportunities for undergraduate students, medical students, or residents to contribute meaningfully in collecting data from patients, and analyzing results.
