Pre- and Post-Implementation of One-Hour Rule for the Boarding of Referral of Critically Ill Patients in the Emergency Department.

In 2017, the Taiwan Ministry of Health and Welfare established a regional electronic referral system in Central Taiwan to streamline transfers of critically ill patients from the intensive care unit (ICU) of a regional hospital to a medical hospital center. Moreover, in 2018, a one-hour rule for the boarding of referral of critically ill patients from emergency department (ED) to ICU was implemented. This pre- and post-implementation study enrolled consecutive critically ill referral patients from a single academic medical center hospital from January 1, 2017 to December 31, 2018. After implementation of the one-hour rule, two interventions, namely, active bed management before patient arrival and no requirement for laboratory test results to be completed before ICU admissions, were used to improve patient flow in the ED. After implementation of one-hour rule, the proportion of patients transferred to the ICU within 1 hour increased from 3.1% to 65.9% (p < 0.001). Median ED length of stay (LOS) reduced from 129.5 minutes to 52.0 minutes (p < 0.001). The overall mortality rate decreased from 34.4% to 26.8%, without a significant difference. In conclusion, the implementation of the one-hour rule for the boarding of referral of critically ill patients in the ED is safe and possible. Achieving the target significantly reduced ED LOS by 77.5 minutes without an increase in patient mortality rate.

Prehospital Predictors of Initial Shockable Rhythm in Out-of-Hospital Cardiac Arrest: Findings From the Taichung Sudden Unexpected Death Registry (THUNDER).

OBJECTIVE: To identify the incidence and prehospital predictors of ventricular tachycardia/ventricular fibrillation (VT/VF) as the initial arrhythmia in patients with out-of-hospital cardiac arrest (OHCA) in central Taiwan. PATIENTS AND METHODS: The Taichung Sudden Unexpected Death Registry program encompasses the Taichung metropolitan area in central Taiwan, with a population of 2.7 million and 17 destination hospitals for patients with OHCA. We performed a detailed analysis of demographic characteristics, circumstances of cardiac arrest, and emergency medical service records using the Utstein Style. RESULTS: From May 1, 2013, through April 30, 2014, resuscitation was attempted in 2013 individuals with OHCA, of which 384 were excluded due to trauma and noncardiac etiologies. Of the 1629 patients with presumed cardiogenic OHCA, 7.9% (n=129) had initial shockable rhythm; this proportion increased to 18.8% (61 of 325) in the witnessed arrest subgroup. Male sex (odds ratio [OR], 2.45; 95% CI, 1.46-4.12; P<.001), age younger than 65 years (OR, 2.39, 95% CI, 1.58-3.62; P<.001), public location of arrest (OR, 4.61; 95% CI, 2.86-7.44; P<.001), and witnessed status (OR, 3.98; 95% CI, 2.62-6.05; P<.001) were independent predictors of VT/VF rhythm. CONCLUSION: The proportion of patients with OHCA presenting with VT/VF was generally low in this East Asian population. Of the prehospital factors associated with VT/VF, public location of OHCA was the strongest predictor of VT/VF in this population, which may affect planning and deployment of emergency medical services in central Taiwan.
