Regular monitoring of vital signs is key to early identification of patient deterioration and provision of rapid response. This hospital in Norway determined inconsistent documentation of vital signs could be a barrier to successful implementation of a rapid response system (RRS). During the decade following introduction and refinement of the RRS, the number of completed vital sign sets increased, as did intensive care consultation, another component of RRS. Overall the RSS was associated with a reduction of in-hospital and 30-day mortality rates.
