Core Outcome Measures in Effectiveness Trials

Developing a core outcome set to measure the effectiveness of critical care outreach systems

General Information

Critical care outreach teams were developed on the premise that early detection and prompt resuscitation of acutely deteriorating ward patients would prevent trajectory to serious adverse events including cardiac arrest, unanticipated intensive care admission, and death. Although the concept of outreach teams has been embraced globally, the clinical and cost effectiveness has not been borne out in the literature. This is in part due to the heterogeneity in care models, given the paucity of evidence in how to structure a team, but also due to the lack of consistent and clear outcomes to measure. Therefore it is difficult to analyse systems and performance nationally or internationally. Anecdotal evidence suggests outreach teams are beneficial but this is controversial in the literature. A consistent method of reporting research is required to build a sound evidence base to justify current expenditure and secure future funding.
