Abdominoplasty risk calculator (unplanned reoperation)
Risk calculators are an emerging tool that provide granular, individualized risk estimation. Presently, there is a paucity of risk calculators specific to plastic surgery. Abdominoplasty is a popular plastic surgery procedure associated with moderate risks of complications, such as surgical-site infection and dehiscence, and would benefit from the ability to provide patients with accurate, personalized risk assessment.

An internally valid risk calculator was developed for which individual patient characteristics can be input to predict 30-day complications after abdominoplasty. Given that estimated risk can vary widely, individualized risk assessment is a way to enhance shared decision-making between surgeon and patient.

    Additional information

    A total of 2499 cases performed between 2005 and 2014 met inclusion criteria and were included in the analysis. The mean age and body mass index were 46 ± 12 years and 29.1 ± 5.8 kg/m2 , respectively. Importantly, 9.4 percent of patients were smokers within the previous year, 13.6 percent of patients had American Society of Anesthesiologists classes of 3 or greater, 21.2 percent of patients had hypertension requiring medication, and 6 percent of patients had diabetes. Pulmonary comorbidities and bleeding disorders were relatively rare.
