Abstract Aims To determine whether cardiac arrest calls, the proportion of adult patients admitted to intensive care after CPR and their associated mortalities were reduced, in a four year period after the introduction of a 24/7 Critical Care Outreach Service and MEWS (Modified Early Warning System) Charts. Methods A retrospective analysis of prospectively collected data during two four-year periods, (2002–05 and 2006–09) in a UK University Teaching Hospital Comparisons were via χ 2 test. A p value of ≤0.05 was regarded as being significant. Results In the second audit period, compared to the first one, the number of cardiac arrest calls relative to adult hospital admissions decreased significantly (0.2% vs. 0.4%; p p = 0.004) as did the in-hospital mortality of these patients (42% vs. 52%; p = 0.05). Conclusion The four years following the introduction of a 24/7 Critical Care Outreach Service and MEWS Charts were associated with significant reductions in the incidence of cardiac arrest calls, the proportion of patients admitted to intensive care having undergone in-hospital CPR and their in-hospital mortality.
