A cost-effectiveness analysis of long-term intermittent catheterisation with hydrophilic and uncoated catheters

Study design: Cost-effectiveness analysis Objective: To establish a model to investigate the cost effectiveness for people with spinal cord injury (SCI), from a lifetime perspective, for the usage of two different single-use catheter designs: hydrophilic-coated (HC) and uncoated (UC). The model includes the long-term sequelae of impaired renal function and urinary tract infection (UTI). Setting: Analysis based on a UK perspective. Methods: A probabilistic Markov decision model was constructed, to compare lifetime costs and quality-adjusted life years, taking renal and UTI health states into consideration, as well as other catheter-related events. UTI event rates for the primary data set were based on data from hospital settings to ensure controlled and accurate reporting. A sensitivity analysis was applied to evaluate best-and worst-case scenarios. Results: The model predicts that a 36-year-old SCI patient with chronic urinary retention will live an additional 1.4 years if using HC catheters compared with UC catheters, at an incremental cost of 2100 pound. Moreover, the lifetime number of UTI events will be reduced by 16%. All best-and worst-case estimates were within the UK threshold of being cost effective. Conclusion: The use of HC catheters for intermittent catheterisation in SCI patients is highly cost effective. The outcome is consistent irrespective of whether UTI data are collected in hospital or community settings.
