Abstract
BackgroundInternationally, emergency departments are struggling with crowding and its associated morbidity, mortality, and decreased patient and health-care worker satisfaction. The objective was to evaluate the addition of a MDRNSTAT (Physician (MD)-Nurse (RN) Supplementary Team At Triage) on emergency department patient flow and quality of care.MethodsPragmatic cluster randomized trial. From 131 weekday shifts (8:00–14:30) during a 26-week period, we randomized 65 days (3173 visits) to the intervention cluster with a MDRNSTAT presence, and 66 days (3163 visits) to the nurse-only triage control cluster. The primary outcome was emergency department length-of-stay (EDLOS) for patients managed and discharged only by the emergency department. Secondary outcomes included EDLOS for patients initially seen by the emergency department, and subsequently consulted and admitted, patients reaching government-mandated thresholds, time to initial physician assessment, left-without being seen rate, time to investigation, and measurement of harm.ResultsThe intervention’s median EDLOS for discharged, non-consulted, high acuity patients was 4:05 [95th% CI: 3:58 to 4:15] versus 4:29 [95th% CI: 4:19–4:38] during comparator shifts. The intervention’s median EDLOS for discharged, non-consulted, low acuity patients was 1:55 [95th% CI: 1:48 to 2:05] versus 2:08 [95th% CI: 2:02–2:14]. The intervention’s median physician initial assessment time was 0:55 [95th% CI: 0:53 to 0:58] versus 1:21 [95th% CI: 1:18 to 1:25]. The intervention’s left-without-being-seen rate was 1.5% versus 2.2% for the control (p = 0.06). The MDRNSTAT subgroup analysis resulted in significant decreases in median EDLOS for discharged, non-consulted high (4:01 [95th% CI: 3:43–4:16]) and low acuity patients (1:10 95th% CI: 0:58–1:19]), as well as physician initial assessment time (0:25 [95th% CI: 0:23–0:26]). No patients returned to the emergency department after being discharged by the MDRNSTAT at triage.ConclusionsThe intervention reduced delays and left-without-being-seen rate without increased return visits or jeopardizing urgent care of severely ill patients.Trial registration numberNCT00991471 ClinicalTrials.gov

Emergency departments are struggling with crowding and its associated morbidity, mortality, and decreased patient and health-care worker satisfaction
The primary objective of this study is to examine the impact and limitations of adding 6.5 hours of MDRNSTAT on Emergency department (ED) length-of-stay (EDLOS) among non-consulted, discharged patients seen by the emergency physician
Sunnybrook Emergency Department received 45000-patient visits per year with an admission rate of 22%
Summary
Emergency departments are struggling with crowding and its associated morbidity, mortality, and decreased patient and health-care worker satisfaction. In Ontario, discharged patients with longer ED length-of-stay (EDLOS) had higher subsequent hospital admission rates and short-term mortality [4]. Crowding increases both mortality and costs [4,5,6,7,8,9]. This problem is international [2,5,10,11] in scope and impacts [1,2,5,10,11,12,13] governments, [10,14] insurers [7], hospitals, health care workers [11], and patients [4]
