Outcome and costs of intensive care. A follow-up study on patients requiring prolonged mechanical ventilation

This historically prospective study analysed hospital costs and long-term outcome in 249 consecutive patients who required intensive care including intermittent positive pressure ventilation (IPPV) for 48 h or more. The mean age of the patients was 46.7 years and the mean duration on IPPV was 9.1 days. Mortality in hospital was 43%, increasing to 54.6% five years after admission. The mean cost per patient treated was 22,823 US dollars (USD (1980 value]. The mean cost to yield one survivor was 40,035 USD. The mean cost per survivor was 26,056 USD, whereas that of a non-survivor was 18,500 USD. The cost-benefit ratio, i.e. calculated cost per year of extended life until the age of 75 years, averaged 1420 USD (range 360-7980 USD). With the exception of patients suffering from cancerous diseases, the cost-benefit ratio found in this study was favourable in comparison to other high-cost medical care. This is further emphasized by the fact that for the years saved, the quality of life was mostly good.
