Abstract PDF: Background
In patients with out-of-hospital cardiac arrest (OHCA), guidelines recommend advanced airway (AA) management at the advanced cardiovascular life support stage; however, the ideal timing remains controversial. Therefore, we evaluated the prognosis according to the timing of AA in patients with OHCA.
Methods
We conducted a retrospective observational study of patients with OHCA at six major hospitals in Daegu Metropolitan City, South Korea, from August 2019 to June 2022. We compared groups with early and late AA and evaluated prognosis, including recovery of spontaneous circulation (ROSC), survival to discharge, and neurological evaluation, according to AA timing.
Results
Of 2,087 patients with OHCA, 945 underwent early AA management and 1,142 underwent late AA management. The timing of AA management did not influence ROSC in the emergency department (5–6 minutes: adjusted odds ratio [aOR], 0.97; p=0.914; 7–9 minutes: aOR, 1.37; p=0.223; ≥10 minutes: aOR, 1.32; p=0.345). The timing of AA management also did not influence survival to discharge (5–6 minutes: aOR, 0.79; p=0.680; 7–9 minutes: aOR, 1.04; p=0.944; ≥10 minutes: aOR, 1.86; p=0.320) or good neurological outcomes (5–6 minutes: aOR, 1.72; p=0.512; 7–9 minutes: aOR, 0.48; p=0.471; ≥10 minutes: aOR, 0.96; p=0.892).
Conclusion
AA timing in patients with OHCA was not associated with ROSC, survival to hospital discharge, or neurological outcomes.

Background
To prepare for future work stoppages in the medical industry, this study aimed to identify the effects of healthcare worker strikes on the mortality rate of patients visiting the emergency department (ED) at six training hospitals in Daegu, Korea.
Methods
We used a retrospective, cross-sectional, multicenter design to analyze the medical records of patients who visited six training hospitals in Daegu (August 21–September 8, 2020). For comparison, control period 1 was set as the same period in the previous year (August 21–September 8, 2019) and control period 2 was set as July 1–19, 2020. Patient characteristics including age, sex, and time of ED visit were investigated along with mode of arrival, length of ED stay, and in-hospital mortality. The experimental and control groups were compared using t-tests, and Mann-Whitney U-test, chi-square test, and Fisher exact tests, as appropriate. Univariate logistic regression was performed to identify significant factors, followed by multivariate logistic regression analysis.
Results
During the study period, 31,357 patients visited the ED, of which 7,749 belonged to the experimental group. Control periods 1 and 2 included 13,100 and 10,243 patients, respectively. No significant in-hospital mortality differences were found between study periods; however, the results showed statistically significant differences in the length of ED stay.
Conclusion
The ED resident strike did not influence the mortality rate of patients who visited the EDs of six training hospitals in Daegu. Furthermore, the number of patients admitted and the length of ED stay decreased during the strike period.
