In a previous issue of Critical Care Jones and colleagues report their analysis of the impact on outcomes of METs in hospitals in Australasia and link this to reports appearing in the world literature. The difficulty with evaluating an intervention once it has become part of established practice is that like servicing a car in motion the method is inconvenient and the results unreliable. Moreover the intervention is likely to have acquired both adherents and detractors thereby ensuring maximal uncertainty while impairing individual equipoise. We are left with performing retrospective observational before-and-after studies relying on large numbers to minimise confounding. This is what Daryl Jones and his colleagues 1 have done. Outcomes were obtained from the Australia and New Zealand Intensive Care Society ANZICS database. From a pool of 172 Australia and New Zealand hospitals the presence or absence of a medical emergency team MET could be determined in 131 of which 84 64 had established an MET. Of the 84 hospitals with an MET 24 provided adequate data to the ANZICS .
