Cost-utility analysis of home parenteral nutrition.

An economic evaluation of home parenteral nutrition (HPN) for intestinal failure is presented. The cost-utility of HPN and factors affecting the cost-utility ratio were examined to determine whether current practice is the most efficient way of treating intestinal failure. Quality-adjusted life-years (QALYs) gained were measured using a validated health status questionnaire. The cost of treating a patient with intestinal failure was calculated, and marginal cost per QALY gained ratios were obtained. The cost per QALY for an average patient was approximately 68,975 pounds, but the value for patients over 55 years of age of about 126,865 pounds compared with approximately 58,233 pounds for those under 44 years. Treating a patient in hospital rather than at home increased the estimated cost per QALY to approximately 190,000 pounds. The current practice of home care is about 65 per cent more cost-effective than hospital care.
