Cost-effectiveness of a novel, non-active implantable device as a treatment for refractory gastro-esophageal reflux disease

The Economic Impact of Introducing RefluxStop for Refractory Gastroesophageal Reflux Disease on the Italian Healthcare System

INTRODUCTION

Gastroesophageal reflux disease (GERD) is a common ailment associated with troublesome symptoms. The standard of care in Italy involves initial treatment with proton pump inhibitor (PPI)-based medical management or laparoscopic Nissen fundoplication (LNF) for patients unwilling to continue or intolerant of long-term PPI therapy. RefluxStop is a novel medical device, intended for laparoscopic implantation, that has recently proven to be an efficacious and cost-effective treatment option for patients with GERD. This analysis aims to describe the short-term budget impact of introducing RefluxStop as a GERD treatment option within the Italian National Health Service (SSN).

METHODS

A model adherent to international best practice recommendations was developed to estimate the budget impact of introducing RefluxStop over a 5-year time horizon. Two scenarios were considered: one without RefluxStop (i.e., comprising PPI therapy, LNF, and magnetic sphincter augmentation using the LINX system); and one with RefluxStop (i.e., addition of RefluxStop to the three treatment options previously mentioned). Clinical benefits and costs associated with each intervention were included in the analysis.

RESULTS

Over 5 years, the introduction of RefluxStop resulted in avoidance of 95 surgical failures, 11 reoperations, and 64 endoscopic esophageal dilations. Introduction of RefluxStop resulted in an almost neutral impact on the existing budget with a 0.316% increase in the annual Italian SSN spending on GERD treatment.

CONCLUSION

Introduction of RefluxStop as a GERD treatment option in Italy is likely to be associated with substantial clinical benefits and a marginal budget impact.

Budget Impact of RefluxStop™ as a Treatment for Patients with Refractory Gastro-oesophageal Reflux Disease in the United Kingdom

Background: Gastro-oesophageal reflux disease (GORD) is a common condition associated with heartburn and regurgitation. Standard of care for GORD patients in the UK involves initial treatment with proton pump inhibitors (PPIs) and laparoscopic antireflux surgery in patients unwilling to continue or intolerant of long-term PPI treatment. Recently, RefluxStop™, a novel, implantable medical device, has proven to be an efficacious and cost-effective treatment for patients with GORD. The current analysis aimed to describe the budget impact of introducing RefluxStop™ within National Health Service (NHS) England and Wales. Objectives: To estimate the more immediate, short-term clinical and economic effects of introducing RefluxStop™ as a therapeutic option for patients with GORD treated within NHS England and Wales. Methods: A model adherent to international best practice guidelines was developed to estimate the budget impact of introducing RefluxStop™ over a 5-year time horizon, from an NHS perspective. Two hypothetical scenarios were considered, one without RefluxStop™ (comprising PPI treatment, laparoscopic Nissen fundoplication, and magnetic sphincter augmentation using the LINX® system) and one with RefluxStop™ (adding RefluxStop™ to the aforementioned treatment options). Clinical benefits and costs associated with each intervention were included in the analysis. Results: Over 5 years, introducing RefluxStop™ allowed the avoidance of 347 surgical failures, 39 reoperations, and 239 endoscopic esophageal dilations. The financial impact of introducing RefluxStop™ was £3 029 702 in year 5, corresponding to a 1.68% increase in annual NHS spending on GORD treatment in England and Wales. Discussion: While the time horizon was too short to capture some of the adverse events of PPIs and complications of GORD, such as the development of Barrett's esophagus or esophageal cancer, the use of RefluxStop™ was associated with a substantial reduction in surgical complications, including surgical failures, reoperations, and endoscopic esophageal dilations. This favorable clinical profile resulted in cost offsets for the NHS and contributed to the marginal budget impact of RefluxStop™ estimated in the current analysis. Conclusions: Introducing RefluxStop™ as a treatment option for patients with GORD in England and Wales may be associated with clinical benefits at the expense of a marginal budget impact on the NHS.

Cost-effectiveness of the RefluxStop device for management of refractory gastroesophageal reflux disease in Switzerland

BACKGROUND

One of the most prevalent conditions in Western societies is gastroesophageal reflux disease (GERD). In Switzerland, the standard treatment for GERD is proton pump inhibitor (PPI)-based medical management, but surgical options such as Nissen fundoplication and magnetic sphincter augmentation (MSA) are available. RefluxStop is a novel device that offers an alternative solution. The purpose of this report is to evaluate the cost-effectiveness of RefluxStop compared to PPIs and existing surgical treatments.

METHODS

A model (Markov) was developed using the Swiss healthcare payer perspective with a lifetime horizon, 1-month cycle length, and a 3% annual discount rate for costs and benefits. Adverse events specific to treatment arms were incorporated, and benefits were measured in quality-adjusted life-years (QALYs). Clinical efficacy data for RefluxStop was obtained from its CE mark study, and comparator treatments were based on published literature. Deterministic and probabilistic sensitivity analyses were used to explore uncertainty. Since there are no head-to-head studies between RefluxStop and PPI therapy, Nissen fundoplication, or MSA, a limitation of this study is the use of naïve, indirect comparison of clinical effectiveness between the studied treatment options.

RESULTS

Higher QALYs and lower costs were provided by RefluxStop compared to Nissen fundoplication and the MSA system. The incremental cost-effectiveness ratio (ICER) for RefluxStop was CHF 2,116 in comparison to PPI-based medical management. At a cost-effectiveness threshold of CHF 100,000 per QALY gained, the probability of RefluxStop being cost-effective was high, with probabilities of 100%, 97%, and 100% against PPI-based medical management, Nissen fundoplication, and MSA, respectively. The robustness of the analysis was provided by deterministic and probabilistic sensitivity analyses.

CONCLUSION

This cost-effectiveness analysis demonstrates that there is a high likelihood of RefluxStop being a cost-effective treatment modality in adults with GERD when compared with other treatment options available in Switzerland.
