Risk factors and exploratory clustering of complications after reconstruction following Mohs surgery: A national NIH All of Us study.

The overall complication rates were 3.2% at 30 days and 11.9% at 1 year.

In multivariable models, primary closure was associated with lower odds of 1-year complications, whereas older age and male sex were associated with higher odds.

BMI significantly predicted individual complications (e.g., cellulitis and wound dehiscence) in univariate models but was not independently significant in multivariable analysis.

Hypertension and diabetes were associated with cellulitis, hematoma, dehiscence, and nerve injury.
