A cost-effectiveness analysis of Navina Smart on adult patients affected by neurogenic bowel dysfunction

Abstract

Background and Objectives: The objective of this study is to evaluate the economic impact of the device Navina Smart on patients affected by neurogenic bowel dysfunction and dependent on transanal irrigation within the Italian context. This study employs the perspective of the Italian National Health Service. Methods: The analysis was conducted through a Markov model, comparing two scenarios: standard bowel care vs. transanal irrigation. The model operates on a 30-year time period. The results were reported in terms of net monetary benefit. Results: Transanal irrigation therapy was dominant in all scenarios with lower costs and higher effectiveness. The population was assumed to be composed of 1,000 subjects. Setting the willingness to pay at €35,000.00/QALYs (quality-adjusted life years), the analysis yielded a net monetary benefit of €81,087 and cost savings of €66,101 per patient over 30 years. Conclusion: The results of this study substantiate that transanal irrigation therapy treatment employing the Navina Smart device can significantly benefit patients suffering from neurogenic bowel dysfunction by relieving their symptoms. In addition, this therapy offers important cost savings for the Italian National Health Service by reducing resource utilization.
