Long-Term Cost-Effectiveness of Transanal Irrigation in Patients with Neurogenic Bowel Dysfunction

BACKGROUND: People suffering from neurogenic bowel dysfunction (NBD) and an ineffective bowel regimen often suffer from fecal incontinence (FI) and related symptoms, which have a huge impact on their quality of life. In these situations, transanal irrigation (TAI) has been shown to reduce these symp...

Sumario:BACKGROUND: People suffering from neurogenic bowel dysfunction (NBD) and an ineffective bowel regimen often suffer from fecal incontinence (FI) and related symptoms, which have a huge impact on their quality of life. In these situations, transanal irrigation (TAI) has been shown to reduce these symptoms and improve quality of life. AIM: To investigate the long-term cost-effectiveness of initiating TAI in patients with NBD who have failed standard bowel care (SBC). METHODS: A deterministic Markov decision model was developed to project the lifetime health economic outcomes, including quality-adjusted life years (QALYs), episodes of FI, urinary tract infections (UTIs), and stoma surgery when initiating TAI relative to continuing SBC. A data set consisting of 227 patients with NBD due to spinal cord injury (SCI), multiple sclerosis, spina bifida and cauda equina syndrome was used in the analysis. In the model a 30-year old individual with SCI was used as a base-case. A probabilistic sensitivity analysis was applied to evaluate the robustness of the model. RESULTS: The model predicts that a 30-year old SCI patient with a life expectancy of 37 years initiating TAI will experience a 36% reduction in FI episodes, a 29% reduction in UTIs, a 35% reduction in likelihood of stoma surgery and a 0.4 improvement in QALYs, compared with patients continuing SBC. A lifetime cost-saving of £21,768 per patient was estimated for TAI versus continuing SBC alone. CONCLUSION: TAI is a cost-saving treatment strategy reducing risk of stoma surgery, UTIs, episodes of FI and improving QALYs for NBD patients who have failed SBC.
