Surgical Risk / Benefit Calculator
Welcome to the MBSAQIP Bariatric Surgical Risk/Benefit Calculator. With this tool you can enter preoperative information about your patient to provide estimates regarding your patient’s risk of postoperative complications, remission of weight-related comorbidities, and weight loss for each of four primary bariatric surgical procedures.
Effective May 26, 2022, the Bariatric Surgical Risk/Benefit Calculator is using updated parameters derived from more current data. This will yield differences in results between the prior and the updated Risk Calculator, though they should be small.
Disclaimer: The MBSAQIP Bariatric Surgical Risk/Benefit Calculator estimates the chance of an unfavorable outcome (such as a complication or death), the chance of remission of weight-related comorbidities, and the patient’s BMI, weight change, and percent total weight change after surgery. These quantities are estimated based upon information the patient gives the healthcare provider about prior health history. The estimates are calculated using data from a large number of patients who had a primary bariatric surgical procedure similar to the one the patient may have.
Please note the risk percentages, remission percentages, BMI, weight change, and percent total weight change provided to you by the risk/benefit calculator are only estimates. These estimates only take certain information into account. There may be other factors that are not included in the estimate which may increase or decrease the risk of a complication, the chance of remission of a weight-related comorbidity, or the amount of weight the patient loses. These estimates are not a guarantee of results. A complication after surgery may happen even if the risk is low, a weight-related comorbidity may not go into remission even if the chances are high, and a patient may lose more or less weight than predicted. This information is not intended to replace the advice of a doctor or healthcare provider about the diagnosis, treatment, or potential outcomes. MBSAQIP is not responsible for medical decisions that may be made based on the risk/benefit calculator estimates, since these estimates are provided for informational purposes. Patients should always consult their doctor or other health care provider before deciding on a treatment plan.
