Maximum emergency department overcrowding is correlated with occurrence of unexpected cardiac arrest

Abstract Background Emergency department overcrowding negatively impacts critically ill patients and could lead to the occurrence of cardiac arrest. However, association between emergency department crowding and occurrence of in-hospital cardiac arrest has not been thoroughly investigated. This study aimed to evaluate the correlation between emergency department occupancy rates and incidence of in-hospital cardiac arrest. Methods A single-center, observational, registry-based cohort study was performed including all consecutive adult, non-traumatic in-hospital cardiac arrest patients between January 2014 and June 2017. We used emergency department occupancy rates as a crowding index at time of presentation time of cardiac arrest and at the time of maximum crowding, and the average crowding rate for the duration of emergency department stay for each patient. To calculate incidence rate, we divided the number of arrest cases for each emergency department occupancy period by accumulated time. The primary outcome is association between the incidence of in-hospital cardiac arrest and emergency department occupancy rates. Results During the study period, 629 adult, non-traumatic cardiac arrest patients were enrolled in our registry. Among these, 187 patients experienced in-hospital cardiac arrest. Overall survival discharge rate was 24.6%, and 20.3% of patients showed favorable neurologic outcomes at discharge. Emergency department occupancy rates were positively correlated with in-hospital cardiac arrest occurrence. Moreover, maximum emergency department occupancy in the critical zone had the strongest positive correlation with in-hospital cardiac arrest occurrence (Spearman rank correlation ρ = 1.0, P < .01). Meanwhile, occupancy rates were not associated with the ED mortality. Conclusion Maximum emergency department occupancy was strongly associated with in-hospital cardiac arrest occurrence. Adequate monitoring and managing the maximum occupancy rate would be important to reduce unexpected cardiac arrest.

Abstract Background Emergency department overcrowding negatively impacts critically ill patients and could lead to the occurrence of cardiac arrest. However, associations between emergency department crowding and occurrence of both in-hospital cardiac arrest and out-of-hospital cardiac arrest have not been thoroughly investigated. This study aimed to evaluate the correlation between emergency department occupancy rates and incidence of in-hospital and out-of-hospital cardiac arrest. Methods A single-center, observational, registry-based cohort study was performed including all consecutive adult, non-traumatic cardiac arrest patients between January 2014 and June 2017. We used emergency department occupancy rates as a crowding index at time of presentation time of cardiac arrest and at the time of maximum crowding, and the average crowding rate for the duration of emergency department stay for each patient. To calculate incidence rate, we divided the number of arrest cases for each emergency department occupancy period by accumulated time. The primary outcome is association between the incidence of in-hospital cardiac arrest and out-of-hospital cardiac arrest and emergency department occupancy rates. Results During the study period, 629 adult, non-traumatic cardiac arrest patients were enrolled in our registry. Among these, 187 patients experienced in-hospital cardiac arrest and 442 patients had out-of-hospital cardiac arrest. In-hospital cardiac arrest patients compared to out-of-hospital cardiac arrest patients had a significantly higher return of spontaneous circulation rates (16.5% vs. 4.8%; P < .01) and better neurologic outcomes at discharge (cerebral performance category scales 4.7 vs. 4.0; P < .01). Emergency department occupancy rates were positively correlated with in-hospital cardiac arrest occurrence. Moreover, maximum emergency department occupancy in the critical zone had the strongest positive correlation with in-hospital cardiac arrest occurrence (Spearman rank correlation ρ = 1.0, P < .01). Out-of-hospital cardiac arrest incidence was negatively correlated with emergency department occupancy (ρ = -0.79, P = .04). Conclusion Maximum emergency department occupancy was strongly associated with in-hospital cardiac arrest occurrence, while occupancy rate was negatively correlated with out-of-hospital cardiac arrest incidence.

Objective: Survival-to-discharge rates following in-hospital cardiac arrest (IHCA) patients remain significantly low. The use of initial documented cardiac rhythm as predictor of Survival-to-discharge is still unclear. This study aimed to assess whether the initial documented rhythm can be used as a predictor of survival-to-discharge following IHCA in an emergency department of the tertiary care referral institute, south India. Methods: This observational study was conducted for six months from January to June 2017 among all patients above 12 years, with witnessed cardiac arrest after arrival at the emergency department. After obtaining informed consent from the patients’ caregivers, data of socio-demographic details, previous relevant medical history, initial documented rhythm, neurologic status and survival-to-discharge were collected and analyzed. Results: The mean age of participants was 50 ± 17.15 years. Of the 252 study participants, 77.4% had non-shockable and 22.6% had shockable rhythm as initial documented rhythm. The overall survival-to-discharge rate was 17.5% (n=44) in our study. The overall proportion of participants who survived to discharge after IHCA was higher among participants with shockable rhythm (16/57, 28%) in comparison to participants with non-shockable rhythm (28/195, 14.3%). These differences were found to be statistically significant. Among the patients with shockable rhythm, 61.1% had good cerebral performance. Conclusion: Survival-to-discharge rates after IHCA can be predicted based on the initial documented cardiac rhythm. Early identification of patients with impending cardiac arrest and providing prompt management of patients with cardiac arrest will improve the survival rates significantly.

Background: Little is known about cardiac arrests (CA) in the Emergency Department (ED). The objective of this study was to determine the characteristics of ED CA’s. Methods: Included were 60,852 adult, in-patient CA index events in the National Registry of Cardiopulmonary Resuscitation. Multiple regression analysis compared ED CA with those occurring in the ICU, telemetry, or general floors. Subgroup analysis examined traumatic vs. non-traumatic ED CA and ED CA occurring after a successful pre-hospital resuscitation (recurrent) vs. primary ED CA. Results: In multivariate analysis, ED location significantly predicted improved survival to discharge (OR 0.74, 95% CI[0.67–0.82], p<0.0001). Patients with CA occurring in the ED had better Cerebral Performance Category scores (ED 1.59, ICU 1.73, Tele 1.96, Floor 1.69, p<0.0001), shorter mean post-event length of stays (ED 8.6, ICU 17.5, Tele 16.5, Floor 14.2 days, p<0.0001) and were less likely to be declared DNR (ED 23.0%, ICU 31.7%, Tele 28.8%, Floor 31.8%, p<0.0001) than CA in other locations. Secondary analysis showed that ED patients with recurrent CA were less likely to survive to discharge (10.1% vs. 24.6%, p<0.0001) and were more likely to be declared DNR (27.9% vs. 22.2%, p<0.0006.) than primary ED CA. Mean length of stay for survivors in both groups was similar (8.85 vs. 8.54 days, p=ns). Major traumatic injury preceded 6.3% of all ED CA. Patients whose ED CA was related to traumatic injury were younger (46.2 vs. 65.0 years, p<0.001), more likely to be male (78.2% vs. 58.1, p<0.0001), less likely to have the CA caused by an arrythmia (23.6% vs. 32.5%, p<0.0008), and more likely to have the CA preceded by hypotension or shock (41.6% vs. 29.0%, p<0.0001) than ED patients whose CA was not due to traumatic injury. ED trauma CA patients had a significantly lower survival to discharge rate than ED patients whose CA was not due to trauma (7.5% vs. 23.8%, p<0.0001). Conclusions: ED CA patients are a unique population and have better survival and neurologic outcomes compared to patients in other hospital locations. Primary ED CA patients have a better chance of survival to discharge than those who re-arrest following a successful pre-hospital resuscitation. Traumatic ED CA patients have worse outcomes than non-traumatic CA.

AbstractWe aimed to investigate whether video-instructed dispatcher-assisted (DA)-cardiopulmonary resuscitation (CPR) improved neurologic recovery and survival to discharge compared to audio-instructed DA-CPR in adult out-of-hospital cardiac arrest (OHCA) patients in a metropolitan city with sufficient experience and facilities. A retrospective cohort study was conducted for adult bystander-witnessed OHCA patients administered DA-CPR due to presumed cardiac etiology between January 1, 2018 and October 31, 2019 in Seoul, Korea. The primary and secondary outcomes were the differences in favorable neurologic outcome and survival to discharge rates in adult OHCA patients in the two instruction groups. Binary logistic regression analysis was performed to identify the outcome predictors after DA-CPR. A total of 2109 adult OHCA patients with DA-CPR were enrolled. Numbers of elderly patients in audio instruction and video instruction were 1260 (73.2%) and 214 (55.3%), respectively. Elderly patients and those outside the home or medical facility were more likely to receive video instruction. Favorable neurologic outcome was observed more in patients who received video-instructed DA-CPR (n = 75, 19.4%) than in patients who received audio-instructed DA-CPR (n = 117, 6.8%). The survival to discharge rate was also higher in video-instructed DA-CPR (n = 105, 27.1%) than in audio-instructed DA-CPR (n = 211, 12.3%). Video-instructed DA-CPR was significantly associated with neurologic recovery (aOR = 2.11, 95% CI 1.48–3.01) and survival to discharge (aOR = 1.81, 95% CI 1.33–2.46) compared to audio-instructed DA-CPR in adult OHCA patients after adjusting for age, gender, underlying diseases and CPR location. Video-instructed DA-CPR was associated with favorable outcomes in adult patients with OHCA in a metropolitan city equipped with sufficient experience and facilities.
