Cost-effectiveness modelling of use of urea breath test for the management of Helicobacter pylori-related dyspepsia and peptic ulcer in the UK.

OBJECTIVE: Clinical data comparing diagnostic strategies in the management of Helicobacter pylori-associated diseases are limited. Invasive and noninvasive diagnostic tests for detecting H. pylori infection are used in the clinical care of patients with dyspeptic symptoms. Modelling studies might help to identify the most cost-effective strategies. The objective of the study is to assess the cost-effectiveness of a 'test-and-treat' strategy with the urea breath test (UBT) compared with other strategies, in managing patients with H. pylori-associated dyspepsia and preventing peptic ulcer in the UK. DESIGN: Cost-effectiveness models compared four strategies: 'test-and-treat' with either UBT or faecal antigen test (FAT), 'endoscopy-based strategy' and 'symptomatic treatment'. A probabilistic cost-effectiveness analysis was performed using a simulation model in order to identify probabilities and costs associated with relief of dyspepsia symptoms (over a 4-week time horizon) and with prevention of peptic ulcers (over a 10-year time horizon). Clinical and cost inputs to the model were derived from routine medical practice in the UK. RESULTS: For relief of dyspepsia symptoms, 'test-and-treat' strategies with either UBT (€526/success) and FAT (€518/success) were the most cost-effective strategies compared with 'endoscopy-based strategy' (€1317/success) and 'symptomatic treatment' (€1 029/success). For the prevention of peptic ulcers, 'test-and-treat' strategies with either UBT (€208/ulcer avoided/year) or FAT (€191/ulcer avoided/year) were the most cost-effective strategies compared with 'endoscopy-based strategy' (€717/ulcer avoided/year) and 'symptomatic treatment' (€651/ulcer avoided/year) (1 EUR=0,871487 GBP at the time of the study). CONCLUSION: 'Test-and-treat' strategies with either UBT or FAT are the most cost-effective medical approaches for the management of H. pylori-associated dyspepsia and the prevention of peptic ulcer in the UK. A 'test-and-treat' strategy with UBT has comparable cost-effectiveness outcomes to the current standard of care using FAT in the UK.

Helicobacter pylori "Test-and-Treat" strategy with urea breath test: A cost-effective strategy for the management of dyspepsia and the prevention of ulcer and gastric cancer in Spain-Results of the Hp-Breath initiative.

BACKGROUND: Data from clinical trials comparing Helicobacter pylori (H. pylori) management strategies in patients with dyspepsia are limited. Cost-effectiveness simulation models might help to identify the optimal strategy. OBJECTIVE: To assess the cost-effectiveness of the H. pylori "Test and Treat" (T&T) strategy including the use of urea breath test (UBT) vs symptomatic treatment (ST) and vs upper gastrointestinal endoscopy (UGE) as a first procedure in patients with dyspepsia. METHODS: Three main strategies: "T&T" strategy including the use of UBT, "UGE" and "ST" have been compared using cost-effectiveness models developed in accordance with the Spanish medical practice. For the model simulations, a time horizon of 4 weeks was considered for the endpoint "Dyspepsia symptoms relief" and 10 years when using "Peptic ulcer avoided" and "Gastric cancer avoided" endpoints. RESULTS: For the endpoint "Dyspepsia symptoms relief", T&T strategy appears to be the most cost-effective (883€/success) compared to UGE strategy and to ST strategy (respectively 1628€ and 990€/success). For the endpoint "Probability of peptic ulcer", the T&T strategy appears to be the most cost-effective (421€/peptic ulcer avoided/y) compared to UGE strategy and ST strategy (respectively 728€ and 632€/peptic ulcer avoided/y). For the endpoint "Gastric cancer avoided", the T&T strategy appears to be the most cost-effective (524€/gastric cancer avoided/y) compared to UGE strategy and "ST" strategy (respectively 716€ and 696€/gastric cancer avoided/y). CONCLUSIONS: T&T strategy including the use of UBT is the most cost-effective medical approach for management of dyspepsia and for the prevention of ulcer and gastric cancer.
