Social Gradients in Myocardial Infarction and Stroke Diagnoses in Emergency Medicine.

BACKGROUND: Persons of lower socio-economic status are at higher risk of disease, especially with respect to severe and chronic illnesses. To date, there have not been any studies with large case numbers regarding acute medical emergencies in this population. METHODS: In a retrospective study, data were obtained on all cases treated by emergency physicians in Bochum, Germany, in 2014/2015, including the diagnoses that were made by the emergency physicians. There were a total of 16 767 cases. The local unemployment rate was taken as an indicator of the socioeconomic situation of a neighborhood; it was defined as the percentage of registered unemployed persons among persons aged 15 to 64 with their domicile in the neighborhood. 12 168 cases were grouped by emergency medical diagnosis and analyzed with respect to the three most heavily represented diagnostic categories (cardiovascular, neurological, and pulmonary emergencies), which accounted for nearly two-thirds of all diagnoses. RESULTS: The overall rates of deployment involving emergency physicians were found to be positively correlated with the unemployment rate. After adjustment for age, sex, and possible confounders, this correlation was statistically significant (p<0.01). The indirectly standardized rate ratio (IRR) for the overall case-activity rate ranged from 0.841 (95% confidence interval: [0.808; 0.875]) with less than 5% unemployment to 1.212 [1.168; 1.256] with 9.5% unemployment or higher. The same finding was obtained with respect to diagnosis-specific case activity in each of the three main diagnostic categories (cardiovascular, neurological, and pulmonary emergencies), as well as for the respective commonest individual diagnoses (acute coronary syndrome/circulatory arrest [1498 cases], transient ischemic attack/ischemic stroke/intracerebral hemorrhage [1274 cases], and asthma/chronic obstructive pulmonary disease [663 cases]). CONCLUSION: This study shows that the case-activity rate of the emergency medical services is significantly higher in socially disadvantaged neighborhoods, both with respect to total numbers and with respect to individual diseases. It demonstrates a problem affecting society as a whole, which should be taken into account in the organization of medical rescue services.

First responder for in-hospital resuscitation: 5-year experience with an automated external defibrillator-based program.

BACKGROUND: The survival of in-hospital cardiac arrest (8-25%) has not changed substantially in the past. Until now, most hospitals in Germany had no standardized protocols available for a course of action in case of emergency, and there are no continuous registry data for in-hospital cardiac arrest and survival. OBJECTIVE: Our aim was to improve survival and receive outcomes data, so we implemented a structured hospital-wide automated first-responder system in the hospital. Here our 5-year experience with 443 emergency calls is outlined. METHODS: Throughout the hospital, 15 automated external defibrillator (AED) "access spots," which can be easily reached within 30 s, were identified. AEDs were then installed at these locations (Lifepak 500 and Lifepak 1000, Medtronic equipped with a Biolog 3000i portable ECG monitor). At the same time, a training program was initiated in which the employees of the hospital participated once a year. Participants learned how to apply and activate an AED in case of cardiac arrest even before the designated Cardiac Arrest Team arrived at the scene. RESULTS: A witnessed cardiac arrest event was confirmed in 126 cases. In 56 of the 126 cases, the primary arrest rhythm was either ventricular tachycardia or ventricular fibrillation and the AED delivered a shock. In this group, spontaneous circulation was reached in 44 cases (79%) and 23 patients (41%) were discharged. In 44% (24 from 55 patients) of the cases, a shock was recommended by AED and delivered by the first responders before the rescue team arrived. CONCLUSIONS: The first-responder AED program successfully gave training lessons to the hospital staff. The training included how to initiate the cardiac arrest call, how to use the AED, and how to start immediate resuscitation. As a result, a higher survival rate after in-hospital cardiac arrest can be accomplished.

Basic life support skills of high school students before and after cardiopulmonary resuscitation training: a longitudinal investigation.

BACKGROUND: Immediate bystander cardiopulmonary resuscitation (CPR) significantly improves survival after a sudden cardiopulmonary collapse. This study assessed the basic life support (BLS) knowledge and performance of high school students before and after CPR training. METHODS: This study included 132 teenagers (mean age 14.6 ± 1.4 years). Students completed a two-hour training course that provided theoretical background on sudden cardiac death (SCD) and a hands-on CPR tutorial. They were asked to perform BLS on a manikin to simulate an SCD scenario before the training. Afterwards, participants encountered the same scenario and completed a questionnaire for self-assessment of their pre- and post-training confidence. Four months later, we assessed the knowledge retention rate of the participants with a BLS performance score. RESULTS: Before the training, 29.5% of students performed chest compressions as compared to 99.2% post-training (P < 0.05). At the four-month follow-up, 99% of students still performed correct chest compressions. The overall improvement, assessed by the BLS performance score, was also statistically significant (median of 4 and 10 pre- and post-training, respectively, P < 0.05). After the training, 99.2% stated that they felt confident about performing CPR, as compared to 26.9% (P < 0.05) before the training. CONCLUSIONS: BLS training in high school seems highly effective considering the minimal amount of previous knowledge the students possess. We observed significant improvement and a good retention rate four months after training. Increasing the number of trained students may minimize the reluctance to conduct bystander CPR and increase the number of positive outcomes after sudden cardiopulmonary collapse.

[In-hospital resuscitation concept with first-responder defibrillation. 2-year experience]. / Innerklinisches notfallmanagement mit "first-responder"-reanimation : 2-jahres-erfahrung.

BACKGROUND AND PURPOSE: Sudden cardiac arrest appears in 1-5 patients/ 1,000 clinical admissions. In spite of different research approaches, the prognosis after in-hospital resuscitation has not significantly improved in the last 40 years. This account presents the experiences with a hospital-wide emergency plan using the concept of defibrillation by first responders. METHODS: In 2003, a hospital-wide emergency plan was implemented. The concept comprised the setup of 15 "defibrillator points", training of the entire hospital personnel as first responder, and the introduction of an emergency team. Over the following 3 years, the concept was optimized. In a period from May 2006 to April 2008, the data of all patients who received an in-hospital resuscitation were collected. RESULTS: Within 24 months, a total of 41 resuscitations were conducted. Out of these, 24 patients (58%) were under intensive monitoring when the event occurred. Initially, 15 patients (36%) showed ventricular fibrillation, 15 (36%) a pulseless electrical activity, and eleven (27%) an asystoly. A total of twelve patients (29%) left hospital alive. About half of them (42%) experienced ventricular fibrillation and were under observation at the time of event. CONCLUSION: The data collected since the implementation of the hospital- wide emergency plan in 2003 reflect the daily clinical routine. The results show that there is a better outcome especially in patients with ventricular fibrillation when receiving first-responder defibrillation.
