Surgeons now have a validated model to predict acute kidney injury in surgical patients, crucial for improving outcomes and reducing costs.

• AKI incidence was 1.8% in the training set and 2.4% in the external validation set.
• The model achieved an AUC of 0.87-0.88 and identified key risk factors: inpatient status, ascites, renal failure, preoperative creatinine, sepsis, ASA classification, and age.

This tool can guide preoperative assessments, allowing targeted interventions to mitigate AKI risk.

• Further studies are needed to refine the model for diverse clinical environments.

A new nationwide surgical registry in Korea reveals important data on 30-day complications, which can help surgeons improve patient selection and surgical outcomes.

• Overall 30-day complication rate is 38.7%, with major complications at 12.7% and mortality at 0.59%.
• Mortality is highest after pancreatic surgery (1.17%) and lowest after gastric surgery (0.16%).

Understanding these results can guide risk assessment in surgical decision-making.

• Colorectal surgery and higher wound class increase surgical site infection risk; chronic pulmonary disease and emergency surgeries elevate pneumonia risk.

Surgeons need to know that patient privilege significantly affects rates of unplanned surgeries and complications in critical procedures.

• 55.4% of patients from low-privilege areas experienced unplanned surgeries compared to 39.4% from high-privilege areas.
• Inpatient mortality was 3.1% for low-privilege patients versus 2.1% for high-privilege; perioperative complications were 30.4% vs 23.8%, respectively.

Consider the role of social determinants of health when evaluating patients for surgical procedures to improve outcomes.
