Ward based non-invasive ventilation is a highly cost effective
treatment that reduces total costs and improves mortality in hospital.
The main reason for the cost saving is reduced use of intensive care
units, according to Plant and colleagues (p 956). They conducted an
economic analysis of a randomised controlled trial in 14 centres, which
included a total of 236 patients admitted to hospital with acute
exacerbations of chronic obstructive pulmonary disease and respiratory
acidosis. Twenty four patients randomised to receive standard treatment
died, compared with 12 randomised to non-invasive ventilation. The cost
saving in the group allocated to non-invasive ventilation was £49 000
($77 975;
70 991).
