Abstract

Background: This study examined the short-term cost-effectiveness and long-term cost of laparoscopic Nissen fundoplication (LNF) versus maintenance proton-pump inhibitor (PPI) medication for severe gastro-oesophageal reflux disease (GORD) based on a randomized clinical trial.

Methods: Costs and outcomes for 12 months were obtained from the first 100 patients in the trial. Detailed costing was performed using resource use data from hospital records and general practitioners' notes. Short-term incremental cost-effectiveness ratios, calculated as the cost difference divided by the effectiveness difference between LNF and PPI therapy, were analysed using net benefit and bootstrap approaches. Long-term cost was examined using sensitivity analyses incorporating published data from other large series.

Results: The incremental cost of LNF compared with PPI therapy per additional patient returned to a physiologically normal acid score (less than 13.9) at 3 months was pound5515 (95 per cent confidence interval (c.i.) pound3655 to pound13 400) and the incremental cost per point improvement in combined Gastro-Intestinal and Psychological Well-being score at 12 months was pound293 (90 per cent c.i. pound149 to pound5250). On average, LNF cost pound2247 (95 per cent c.i. pound2020 to pound2473) more than PPI therapy in year 1 and broke even in year 8. Break-even was highly sensitive to hospital unit costs but less sensitive to PPI ingestion rate after LNF, LNF reoperation rate, PPI relapse rate, future PPI price, PPI dose escalation and discount rate.

Conclusion: From a National Health Service perspective, LNF may be cost-saving after 8 years compared with maintenance PPI therapy for the treatment of GORD.
