The sample included 122 patients (mean age: 56 years, 59.8% men). Clinical, sociodemographic, and functional capacity variables were evaluated and estimated by the Duke Activity Status Index (DASI). Outcomes included clinical complications, early readmission, prolonged hospitalization (&gt; 6 days), and intensive care unit (ICU) stay for more than one day. A logistic regression model was used, with performance evaluated by the C-statistic (area under the curve, AUC), and the model was incorporated into an online tool.<\/jats:p>\n                  <jats:p>The most prevalent comorbidities were hypertension (61%), diabetes (23%), and dyslipidemia (15%). Complications within 30 days occurred in 13.1% of patients, with surgical wound infection and anemia being the most common events. Dyslipidemia (odds ratio [OR]: 4.70; p\u2009=\u20090.010), sedentary lifestyle (OR: 4.71; p\u2009=\u20090.026), high ASA classification (OR: 3.67; p\u2009=\u20090.035), and functional capacity\u2009&lt;\u20094 metabolic equivalents of task (METs) (OR: 4.08; p\u2009=\u20090.040) were significant risk factors.

The model showed good accuracy, and further studies are needed to validate its clinical application.<\/jats:p>\n                  <jats:p>This is a prospective cohort study without a control group
