Optimal surveillance intervals in Barrett's esophagus (example data for cost-effectiveness analysis)
Optimal surveillance intervals in Barrett's esophagus (example data for cost-effectiveness analysis)
Depiction of the optimal endoscopic surveillance intervals in patients with Barrett's esophagus according to the annual incidence of esophageal cancer. More frequent surveillance is associated with increased quality-adjusted life expectancy as the incidence of esophageal cancer increases. In populations with a low incidence of esophageal adenocarcinoma (less than 0.2%), not performing surveillance endoscopy produced the optimal quality-adjusted life expectancy. In contrast, annual surveillance (gray area) was optimal in populations with a high incidence of esophageal adenocarcinoma (more than 2%). These data were derived from a decision analysis using a Markov model.
