Abstract

Aims

To estimate the cost effectiveness of Topical Wound Oxygen therapy (TWO2) for chronic diabetic foot ulcers.

Methods

A Markov model was created to estimate the cost effectiveness of TWO2 over 2 years. Clinical outcome probabilities were estimated from a recent multi-national randomised controlled trial. Diabetic footcare costs were estimated for the National Health Service in England, based on national cost collections, published literature and expert opinion. Model inputs were varied in sensitivity analyses.

Results

Base case results indicate that at a weekly TWO2 price of £650 for up to 12 weeks, total diabetic footcare costs over 2 years are £5038 lower for a patient treated with TWO2 than for standard care, and QALYs are 0.07 higher. Probabilistic sensitivity analysis estimates an 81 % likelihood that the treatment is cost effective at a willingness to pay threshold of £25,000 per QALY.

Conclusions

Base case results indicate that if the clinical outcomes in the RCT are replicated in routine care, TWO2 is a dominant treatment, with lower cost and improved outcomes relative to standard care. Sensitivity analysis shows a high probability that the treatment is cost effective at a willingness to pay threshold of £25,000 per QALY.

期刊介绍： Journal of Diabetes and Its Complications (JDC) is a journal for health care practitioners and researchers, that publishes original research about the pathogenesis, diagnosis and management of diabetes mellitus and its complications. JDC also publishes articles on physiological and molecular aspects of glucose homeostasis. The primary purpose of JDC is to act as a source of information usable by diabetes practitioners and researchers to increase their knowledge about mechanisms of diabetes and complications development, and promote better management of people with diabetes who are at risk for those complications. Manuscripts submitted to JDC can report any aspect of basic, translational or clinical research as well as epidemiology. Topics can range broadly from early prediabetes to late-stage complicated diabetes. Topics relevant to basic/translational reports include pancreatic islet dysfunction and insulin resistance, altered adipose tissue function in diabetes, altered neuronal control of glucose homeostasis and mechanisms of drug action. Topics relevant to diabetic complications include diabetic retinopathy, neuropathy and nephropathy; peripheral vascular disease and coronary heart disease; gastrointestinal disorders, renal failure and impotence; and hypertension and hyperlipidemia.
