ObjectiveThe long-term survival of in-hospital cardiac arrest (IHCA) patients treated with targeted temperature management (TTM) is poorly described. The aim of this study was to compare the outcomes of consecutive IHCA with out-of-hospital cardiac arrest (OHCA) patients treated with TTM.Design, setting, and patientsRetrospectively collected data on all consecutive adult patients treated with TTM at a university tertiary heart center between 2005 and 2011 were analyzed.MeasurementsPrimary endpoints were survival to hospital discharge and long-term survival. Secondary endpoint was neurological outcome assessed using the Pittsburgh cerebral performance category (CPC).ResultsA total of 282 patients were included in this study; 233 (83%) OHCA and 49 (17%) IHCA. The IHCA group presented more often with asystole, received bystander cardiopulmonary resuscitation (CPR) in all cases, and had shorter time to return of spontaneous circulation (ROSC). Survival to hospital discharge was 54% for OHCA and 53% for IHCA (adjusted odds ratio 0.98 [95% confidence interval {CI}; 0.43–2.24]). Age ≤60 years, bystander CPR, time to ROSC ≤10 min, and shockable rhythm at presentation were associated with survival to hospital discharge. Good neurologic outcome among survivors was achieved by 86% of OHCA and 92% of IHCA (P=0.83). After a median follow-up time of >5 years, 83% of OHCA and 77% of IHCA were alive (adjusted hazard ratio [HR] 1.51 [95% CI; 0.59–3.91]). Age ≤60 years was the only factor associated with long-term survival (adjusted HR 2.73 [95% CI; 1.36–5.52]).ConclusionThere was no difference in short- and long-term survival and no difference in neurologic outcome to hospital discharge between IHCA and OHCA patients treated with TTM despite higher frequency of asystole in IHCA.

BackgroundIntraosseous infusion (IOI) is recommended when intravenous access cannot be readily established in both pediatric and adult resuscitation. We evaluated the current use of IOI in Danish emergency departments (EDs).MethodsAn online questionnaire was e-mailed to the Heads of Department of the twenty EDs currently established in Denmark. The questionnaire focused on the use of IOI in the EDs and included questions on frequency of use, training, equipment and attitudes towards IOI.ResultsWe received a total of 19 responses (response rate of 95%). Of the responding 19 Danish EDs 74% (n = 14) reported having intraosseous devices available. The median number of IOI procedures performed in these departments over the preceding 12 months was 5.0 (range: 0-45). In 47% (n = 9) of the departments, prior training sessions in the use of intraosseous devices had not been provided, and 42% (n = 8) did not have local guidelines on IOI. The indication for IOI use was often not clearly defined and only 11% (n = 2) consistently used IOI on relevant indication. This is surprising as 95% (n = 18) of responders were aware that IOI can be utilized in both pediatric and adult resuscitation.ConclusionsThe study shows considerable variations in IOI usage in Danish EDs despite the fact that IOI devices were available in the majority of EDs. In addition, in many EDs there were no local guidelines on IOI and no training in the procedure. We recommend more extensive training of medical staff in IOI techniques in Danish EDs.

Background Citizen responder programmes dispatch volunteer citizens to initiate resuscitation in nearby out-of-hospital cardiac arrests (OHCA) before the Emergency Medical Services (EMS) arrival. Little is known about the interaction between citizen responders and EMS personnel during the resuscitation attempt. In the Capital Region of Denmark, emergency physicians are dispatched to all suspected OHCAs. The aim of this study was to evaluate how emergency physicians perceived the collaboration with citizen responders during resuscitation attempts. Method This cross-sectional study was conducted through an online questionnaire. It included all 65 emergency physicians at Copenhagen EMS between June 9 and December 13, 2019 (catchment area 1.8 million). The questionnaire examined how emergency physicians perceived the interaction with citizen responders at the scene of OHCA (use of citizen responders before and after EMS arrival, citizen responders’ skills in cardiopulmonary resuscitation (CPR), and challenges in this setting). Results The response rate was 87.7% (57/65). Nearly all emergency physicians (93.0%) had interacted with a citizen responder at least once. Of those 92.5%(n = 49) considered it relevant to activate citizen responders to OHCA resuscitation, and 67.9%(n = 36) reported the collaboration as helpful. When citizen responders arrived before EMS, 75.5%(n = 40) of the physicians continued to use citizen responders to assist with CPR or to carry equipment. Most (84.9%, n = 45) stated that citizen responders had the necessary skills to perform CPR. Challenges in the collaboration were described by 20.7%(n = 11) of the emergency physicians and included citizen responders being mistaken for relatives, time-consuming communication, or crowding problems during resuscitation. Conclusion Emergency physicians perceived the collaboration with citizen responders as valuable, not only for delivery of CPR, but were also considered an extra helpful resource providing non-CPR related tasks such as directing the EMS to the arrest location, carrying equipment and taking care of relatives.
