Brief summary

To assess impact of behavioral economic principles of precommitment, implementation intentions, and social contracting on smoking cessation for patients undergoing surgery.

Detailed description

Purpose & Objective: Behavioral interventions in surgical patients are an opportunity to improve outcomes through decreased complications, with measurable economic impact. Smoking cessation is one of the most desirable long-term health behaviors for adults with potential substantial impact on postoperative complications Study Activity & Population Group: The investigators propose a precommitment contractual agreement implementing behavioral economic principles at the preoperative appointment for active tobacco users undergoing an operation and assessing for ability to quit smoking with testing on the day of surgery, and the durability of cessation over the postoperative course as measured with urine nicotine testing at follow up appointments. The population of interest is adults who currently smoke tobacco or vaporized nicotine who are scheduled to undergo a major operation. The control group is standard of care; prescriptive advice to quit smoking. The intervention is contract agreement for preoperative cessation. Data Analysis & Risk Issues: Following informed consent patients will be randomized to control or intervention groups, baseline urine nicotine tests will be performed in clinic. Urine nicotine testing will be performed on the day of enrollment, the day of their operation, and at their one-month follow up appointments. Thirty-day outcomes will be evaluated by retrospective chart review.
