Abstract BackgroundApproximately 100,000 patients suffer from sudden cardiac arrest (CA) annually in Germany. The causes for CA are cardiac in 75% of these cases. The present study aims to investigate the medical prehistory of patients who suffered from out-of-hospital cardiac arrest (OHCA) in a town with 250,000 inhabitants during 5 years and how many of these patients had already been previously treated at the local cardiac arrest center (CAC).Case presentationAll resuscitations due to OHAC were retrospectively analyzed for the cause of OHCA, preexisting cardiac conditions and treatment, lay resuscitation, and outcome from January 1, 2012, to December 31, 2016, in Aachen, Germany. Data analysis was based on the resuscitation protocols and data from the CAC clinical information system. More than 50% of the patients with CA from cardiovascular origin were already known at the receiving respective CAC. Almost 60% of all patients already had cardiac preexisting conditions. Nevertheless, lay resuscitation occurred in only 34.1% of all cases. It was not performed in more than 60% although the probability of discharge can be significantly increased by lay resuscitation.ConclusionThe rate of lay resuscitation is relatively low although many patients suffering from CA have cardiac preexisting conditions. These findings show the importance of better priming their relatives for emergencies to improve lay resuscitation and improve the chances for a better outcome.

Abstract Background Patients who suffer a sudden out-of-hospital cardiac arrest (OHCA) may be preceded by warning symptoms and healthcare system contact. Though, is currently difficult early identification of sudden cardiac arrest patients. Purpose We aimed to examine contacts with the healthcare system up to two weeks and one year before OHCA. Methods OHCA patients were identified from the Danish Cardiac Arrest Registry (2001–2014). The pattern of healthcare contacts (with either general practitioner (GP) or hospital) within the year prior to OHCA of OHCA patients was compared with that of 9 sex- and age-matched controls from the background general population. Additionally, we evaluated characteristics of OHCA patients according to the type of healthcare contact (GP/hospital/both/no-contact) and the including characteristics of contacts, within two weeks prior their OHCA event. Results Out of 28,955 OHCA patients (median age of 72 (62–81) years and with 67% male) of presumed cardiac cause, 16,735 (57.8%) contacted the healthcare system (GP and hospital) within two weeks prior to OHCA. From one year before OHCA, the weekly percentages of contacts to GP were relatively constant (26%) until within 2 weeks prior to OHCA where they markedly increased (54%). In comparison, 14% of the general population contacted the GP during the same period (Figure). The weekly percentages of contacts with hospitals gradually increased in OHCA patients from 3.5% to 6.5% within 6 months, peaking at the second week (6.8%), prior to OHCA. In comparison, only 2% of the general population had a hospital contact in that period (Figure). Within 2 weeks of OHCA, patients contacted GP mainly by telephone (71.6%). Hospital diagnoses were heterogenous, where ischemic heart disease (8%) and heart failure (4.5%) were the most frequent. Conclusions There is an increase in healthcare contacts prior to “sudden” OHCA and overall, 54% of OHCA-patients had contacted GP within 2 weeks before the event. This could have implications for developing future strategies for early identification of patients prior to their cardiac arrest. Figure 1.

AimsOut-of-hospital sudden cardiac arrest (SCA) is a rare but devastating event in children and adolescents. The risk is assumed to be higher in children with congenital heart defects (CHDs) than in healthy individuals. The aim of the present study was to investigate the rate of and survival after out-of-hospital cardiac arrest in children 2–18 years old with CHDs.Methods and resultsData concerning all live births in Norway between 1994 and 2009 were retrieved from the Medical Birth Registry of Norway, the patient administrative systems at all hospitals in Norway, the Oslo University Hospital’s Clinical Registry for Congenital Heart Defects and the Norwegian Cause of Death Registry. Survivors were followed through 2012, and supplementary information for the deceased children was retrieved from medical records at Norwegian hospitals. Among the 943 871 live births in Norway from 1994 to 2009, 11 272 (1.2%) children had a CHD. We identified 11 (0.1%) children 2–18 years old with CHDs who experienced out-of-hospital SCA. The estimated rate of out-of-hospital SCA in children 2–18 years old with CHD was 10 per 100 000 person-years. Early cardiopulmonary resuscitation was initiated in all patients. Three children survived.ConclusionsThe incidence of and survival after out-of-hospital SCA in children with CHDs were comparable to the reported rates in the general child population.

Hospital Cardiac Arrest

Background: Sudden cardiac arrest (SCA) and especially the out of hospital cardiac arrest (OHCA) is always an urgent situation, which requires well trained medical personnel. The emergency medical system (EMS) in Vienna took part in the Circulation Improving Care (CIRC) trial form 2008 to 2010. In this time they had an additional training. Therefore we revaluated the outcome of OHCA nowadays. Method: Interim report of a prospective observational study of all humans over eighteen, who suffer an OHCA resuscitated by the EMS in Vienna from August 2013 - April 2014. For those patients, who survived 30 days, a cerebral performance category score (CPC) was evaluated. Results: During nine months 701 patients could be investigated and 625 achieved the protocol for this trial. The median age of the patients was 68 years (IQR 59-79) and 399 (64%) were male. Witnessed by bystanders was the cardiac arrest in 359 (57%) patients. In the latter patients restoration of spontaneous circulation (n=223, 36%)(ROSC) and 30 day survival (n=166, 27%) was significantly more often achieved than in patients with non-witnessed cardiac arrest. Bystanders provided chest compressions in 284 (45%) cases and in this subgroup a shockable initial rhythm was more often (p<0.0001). Still in 189 (53%) of the patients where the cardiac arrest was witnessed, bystander resuscitation wasn′t attempted. An initial shockable rhythm was found in 146 (24%) patients with significant better outcome in all primary outcome measures. Of the 62 (10%) 30-days-survivors, 33 (6%) had good neurological outcome with a CPC 1-2.In 12 (2%) cases the CPC was missing. Conclusion: The results are comparable to findings of our previous studies. A significant better result in all primary outcome measures could be found for witnessed OHCA with an initial shockable rhythm. Furthermore those patients with bystander CPR had significant more often a shockable initial rhythm. Therefore more efforts have to be invested into encouraging the community to start with a bystander CPR if an OHCA is witnessed.

AbstractIntroduction:To date, there are no published data on the association of patient-centered outcomes and accurate public-safety answering point (PSAP) dispatch in an American population. The goal of this study is to determine if PSAP dispatcher recognition of out-of-hospital cardiac arrest (OHCA) is associated with neurologically intact survival to hospital discharge.Methods:This retrospective cohort study is an analysis of prospectively collected Quality Assurance/Quality Improvement (QA/QI) data from the San Antonio Fire Department (SAFD; San Antonio, Texas USA) OHCA registry from January 2013 through December 2015. Exclusion criteria were: Emergency Medical Services (EMS)-witnessed arrest, traumatic arrest, age <18 years old, no dispatch type recorded, and missing outcome data. The primary exposure was dispatcher recognition of cardiac arrest. The primary outcome was neurologically intact survival (defined as Cerebral Performance Category [CPC] 1 or 2) to hospital discharge. The secondary outcomes were: bystander cardiopulmonary resuscitation (CPR), automated external defibrillator (AED) use, and prehospital return of spontaneous return of circulation (ROSC).Results:Of 3,469 consecutive OHCA cases, 2,569 cases were included in this analysis. The PSAP dispatched 1,964/2,569 (76.4%) of confirmed OHCA cases correctly. The PSAP dispatched 605/2,569 (23.6%) of confirmed OHCA cases as another chief complaint. Neurologically intact survival to hospital discharge occurred in 99/1,964 (5.0%) of the recognized cardiac arrest group and 28/605 (4.6%) of the unrecognized cardiac arrest group (OR = 1.09; 95% CI, 0.71–1.70). Bystander CPR occurred in 975/1,964 (49.6%) of the recognized cardiac arrest group versus 138/605 (22.8%) of the unrecognized cardiac arrest group (OR = 3.34; 95% CI, 2.70–4.11).Conclusion:This study found no association between PSAP dispatcher identification of OHCA and neurologically intact survival to hospital discharge. Dispatcher identification of OHCA remains an important, but not singularly decisive link in the OHCA chain of survival.
