Aiming to be NEAT: safely improving and sustaining access to emergency care in a tertiary referral hospital.

OBJECTIVE: To implement and evaluate strategies for improving access to emergency department (ED) care in a tertiary hospital. METHODS: A retrospective pre-post intervention study using routinely collected data involving all patients presenting acutely to the ED of a major tertiary hospital over a 2-year period. Main outcome measures were changes in: the percentage of patients exiting the ED (all patients, patients discharged directly from the ED, patients admitted to inpatient wards); mean patient transit times in the ED; inpatient mortality rates; rates of ED 'did not wait' and re-presentations within 48 h of ED discharge; and selected safety indicators. Qualitative data on staff perceptions of interventions were also gathered. RESULTS: Working groups focused on ED internal processes, ED-inpatient unit interface, hospital-wide discharge processes and performance monitoring and feedback. Twenty-five different reforms were enacted over a 9-month period from April to December 2012. Comparing the baseline period (January-March 2012) with the post-reform period (January-March 2013), the percentage of patients exiting the ED within 4 h rose for all patients presenting to the ED (from 32% to 62%), for patients discharged directly from the ED (from 41% to 75%) and for admitted patients (from 12% to 32%; P<0.001 for all comparisons). The mean (±s.d.) time all patients spent in the ED was reduced from 7.2±5.8 to 4.4±3.5 h (P<0.001) and, for admitted patients, was associated with reduced in-hospital mortality (from 2.3% to 1.7%; P=0.045). The 'did not wait' rates in ED fell from 6.9% to 1.9% (P<0.001), whereas ED re-presentations within 48 h among patients discharged from the ED rose slightly (from 3.1% to 3.8%; P=0.023). Improvements in outcome measures were maintained over the subsequent 12 months. CONCLUSIONS: Multiple reforms targeting processes both within the ED and its interface with inpatient units greatly improved access to ED care over 12 months and were associated with decreased in-hospital mortality. WHAT IS KNOWN ABOUT THIS TOPIC?: Prolonged stays in the ED result in overcrowding, delayed ambulance access to ED care and increased adverse outcomes for admitted patients. The introduction in Australia of National Emergency Access Targets (NEAT), which stipulate at least 70% of patients in the ED must exit the department within 4h, have spurred hospitals into implementing a wide range of reforms with varying levels of success in achieving such targets. WHAT DOES THIS PAPER ADD?: This study demonstrates how multiple reforms implemented in a poor performing tertiary hospital caused the proportion of patients exiting the ED within 4h to double within 9 months to reach levels comparable with best performing peer hospitals. This was associated with a 26% reduction in in-hospital mortality for admitted patients and no clinically significant adverse effects. It demonstrates the importance of robust governance structures, executive sponsorship, cross-disciplinary collaboration, regular feedback of NEAT performance data and major redesign of existing clinical processes, work practices and bed management operations. WHAT ARE THE IMPLICATIONS FOR CLINICIANS AND MANAGERS?: Improving access to emergency care should be regarded as a problem located and resolved both within and without the ED. It requires a whole-of-hospital solution involving interdisciplinary collaboration and significant change in culture and practice relating to inpatient units and their interface with the ED.
