ABSTRACT
BACKGROUND: In 2010, the acute admissions unit (AAU) at Stirling Royal Infirmary had the highest number of cardiac arrests of any ward. A quality improvement project was undertaken to reduce this to <1/1000 admissions by December 2011. METHODS: In January 2011, based on initial needs assessment, we selected three initiatives to improve cardiac arrest rate: (1) structured response to deteriorating patients; (2) analysis of adverse events; and (3) improved end-of-life decision-making. We performed a failure modes effects analysis to identify reasons for the failure of early recognition and response. Ward staff conducted weekly safety meetings to engage unit staff and promote a safety culture of continuous improvement. Additionally, in July 2011 the unit adopted a ward-based clinical team structure with twice daily consultant ward rounds. Our primary outcome measure, cardiac arrests per 1000 admissions, was measured from January 2011 to August 2012. RESULTS: Over 17 months, the number of cardiac arrests per 1000 admissions fell from a baseline of 2.8/1000 admissions to 0.8/1000 admissions (71% reduction), referrals to palliative care increased by 22 to 37/1000 admissions per month (68% increase) and the 30-day mortality of patients admitted to the AAU fell from 6.3% to 4.8% (24% relative reduction). CONCLUSIONS: Through adoption of a shared goal, application of improvement methodology including the model for improvement to test new innovations, and promotion of a safety culture in the AAU, cardiac arrests were successfully reduced to <1/1000 admissions per month with an associated significant fall in mortality. This was achieved with negligible cost.
