Objective: To assess the cost-effectiveness of surveillance of Barrett's oesophagus.
Design: Cost-utility model.
Setting: UK NHS.
Patients: One thousand 55-year-old men with Barrett's oesophagus.
Intervention: Surveillance programme: endoscopy and biopsy at 3 yearly intervals for non-dysplastic Barrett's oesophagus; low-grade dysplasia yearly; high grade-dysplasia 3 monthly.
Outcome measures: Incremental cost-effectiveness ratio, expected value of perfect information.
Results: Non-surveillance dominated surveillance (i.e. cost less and conferred more benefit), but there was substantial uncertainty around many of the model inputs. Probabilistic analyses showed that non-surveillance cost less and conferred more benefit in 75% of model runs. Surveillance was cost-effective at usual levels of willingness to pay in 11% of runs. For people with Barrett's oesophagus in England and Wales, a value of pound6.5 million is placed on acquiring perfect information about surveillance of Barrett's oesophagus.
Conclusions: The PenTAG cost-utility model suggests that surveillance programmes do more harm than good.
