Abstract
A questionnaire designed to assess changes in quality of life was sent to 56 survivors of critical illness one year after their admission to an intensive therapy unit. Forty‐one patients completed the questionnaire, and for the majority, quality of life remained unchanged (n = 25). However significant decreases in quality of life were found in those patients who previously enjoyed a good quality of life or were admitted with respiratory problems. Survivors also recorded significant decreases in five aspects of their perceived quality of life (ability to think and remember, seeing family, their contribution to society, activities outside work and income). As part of a previous study, the costs incurred by each of these patients had been measured so that changes in quality of life detected in this study could be combined to the individual costs and expressed as cost per quality adjusted life year. The cost of intensive therapy for a patient surviving for one year after acute respiratory or cardiovascular disease was £2600. The total hospital cost per quality adjusted life year was estimated at £7500, which places intensive therapy at the higher end of health programme costs. If the costs of nonsurvivors are included in the cost per quality adjusted life year calculation, the cost of intensive care increases considerably.
