The Medical Emergency Team System and not-for-resuscitation orders: results from the MERIT study

To examine NFR orders in relation to adverse events and emergency team calls in hospitals with or without a Medical Emergency Team (MET) system during the MERIT study. Method: Within a cluster randomized controlled trial (the MERIT study), examining the effect of introducing a MET system, we recorded NFR orders in relation to adverse events and emergency team calls. We compared the proportion and rate of NFR orders issued in relation to adverse events and adverse event-free emergency team calls in hospitals with or without a MET system.
