What this trial studies

This study aims to develop and test a mobile contingency management (CM) intervention designed to help military Veterans quit smoking before undergoing major elective surgery. Given that smoking significantly increases the risk of postoperative complications, the intervention will provide positive reinforcement through rewards for verified abstinence from smoking. The study will tailor the CM approach to the surgical context, ensuring it is feasible and effective for Veterans. By focusing on this high-risk population, the study seeks to improve surgical outcomes and reduce the incidence of complications associated with smoking.

Why it matters

Potential benefit: If successful, this intervention could significantly reduce postoperative complications and mortality rates among Veterans who smoke.

How similar studies have gone: While contingency management has been effective in other smoking cessation contexts, this specific application in the perioperative setting for Veterans is novel and has not been previously tested.
