When choosing a strategy for evaluating patients with lung nodules, clinicians should consider both the probability that the nodule is malignant and the advantages and disadvantages of management strategies. The VA Clinical Model has been validated, is available at no charge, and requires only four simple inputs – smoking status, years since quitting, age, and nodule size in mm or cm. The score generated will place your patient into a risk group (low, intermediate, high) that corresponds to the probability that the nodule is malignant.
