Prehospital cooling in cardiac arrest - the next frontier?

Therapeutic hypothermia (TH) in unconscious survivors of out-of-hospital cardiac arrest (OHCA) is now a well-documented part of post-resuscitation care. Implementation of TH into daily clinical practice has been far more successful in the Scandinavian countries than in the rest of the world. Still, many questions remain. One of them is whether prehospital cooling will result in better outcomes

Successful use of therapeutic hypothermia in an opiate induced out-of-hospital cardiac arrest complicated by severe hypoglycaemia and amphetamine intoxication: a case report

The survival to discharge rate after unwitnessed, non-cardiac out-of-hospital cardiac arrest (OHCA) is dismal. We report the successful use of therapeutic hypothermia in a 26-year old woman with OHCA due to intentional poisoning with heroin, amphetamine and insulin

Prognostication after out-of-hospital cardiac arrest, a clinical survey

Background: Numerous parameters and tests have been proposed for outcome prediction in comatose out-of-hospital cardiac arrest survivors. We conducted a survey of clinical practice of prognostication after therapeutic hypothermia (TH) became common practice in Norway. Methods: By telephone, we interviewed the consultants who were in charge of the 25 ICUs admitting cardiac patients using 6 structured questions regarding timing, tests used and medical specialties involved in prognostication, as well as the clinical importance of the different parameters used and the application of TH in these patients. Results: Prognostication was conducted within 24–48 hours in the majority (72%) of the participating ICUs. The most commonly applied parameters and tests were a clinical neurological examination (100%), prehospital data (76%), CCT (56%) and EEG (52%). The parameters and tests considered to be of greatest importance for accurate prognostication were prehospital data (56%), neurological examination (52%), and EEG (20%). In 76% of the ICUs, a multidisciplinary approach to prognostication was applied, but only one ICU used a standardised protocol. Therapeutic hypothermia was in routine use in 80% of the surveyed ICUs. Conclusion: Despite the routine use of TH, outcome prediction was performed early and was mainly based on prehospital information, neurological examination and CCT and EEG evaluation. Somatosensory evoked potentials appear to be underused and underrated, while the importance of prehospital data, CCT and EEG to appear to be overrated as methods for making accurate predictions. More evidence-based protocols for prognostication in cardiac arrest survivors, as well as additional studies on the effect of TH on known prognostic parameters are needed

Implementing simulation in a nursing education programme: a case report from Tanzania

This paper presents a description of, and some reflections around, the experience of implementing simulation-based education within a nursing education programme in a low-income context. The students in the nursing education programme found the simulation sessions to be useful, motivating and a realistic learning method. Our experience may provide useful insight for other nursing education programmes in low-income contexts. It looks like a deeper knowledge about the feasibility of simulation-based education from both the teacher and student perspective is necessary.publishedVersio

Pre-hospital intubation by anaesthesiologists in patients with severe trauma: an audit of a Norwegian helicopter emergency medical service

<p>Abstract</p> <p>Background</p> <p>Anaesthesiologists are airway management experts, which is one of the reasons why they serve as pre-hospital emergency physicians in many countries. However, limited data are available on the actual quality and safety of anaesthesiologist-managed pre-hospital endotracheal intubation (ETI). To explore whether the general indications for ETI are followed and what complications are recorded, we analysed the use of pre-hospital ETI in severely traumatised patients treated by anaesthesiologists in a Norwegian helicopter emergency medical service (HEMS).</p> <p>Methods</p> <p>A retrospective audit of prospectively registered data concerning patients with trauma as the primary diagnosis and a National Committee on Aeronautics score of 4 - 7 during the period of 1994-2005 from a mixed rural/urban Norwegian HEMS was performed.</p> <p>Results</p> <p>Among the 1255 cases identified, 238 successful pre-hospital ETIs out of 240 attempts were recorded (99.2% success rate). Furthermore, we identified 47 patients for whom ETI was performed immediately upon arrival to the emergency department (ED). This group represented 16% of all intubated patients. Of the ETIs performed in the ED, 43 patients had an initial Glasgow Coma Score (GCS) < 9. Compared to patients who underwent ETI in the ED, patients who underwent pre-hospital ETI had significantly lower median GCS (3 (3-6) vs. 6 (4-8)), lower revised trauma scores (RTS) (3.8 (1.8-5.9) vs. 5.0 (4.1-6.0)), longer mean scene times (23 ± 13 vs. 11 ± 11 min) and longer mean transport times (22 ± 16 vs. 13 ± 14 min). The audit also revealed that very few airway management complications had been recorded.</p> <p>Conclusions</p> <p>We found a very high success rate of pre-hospital ETI and few recorded complications in the studied anaesthesiologist-manned HEMS. However, a substantial number of trauma patients were intubated first on arrival in the ED. This delay may represent a quality problem. Therefore, we believe that more studies are needed to clarify the reasons for and possible clinical consequences of the delayed ETIs.</p

We Are Not There Yet: A Qualitative System Probing Study of a Hospital Rapid Response System

Objectives The capability of a hospital’s rapid response system (RRS) depends on various factors to reduce in-hospital cardiac arrests and mortality. Through system probing, this qualitative study targeted a more comprehensive understanding of how healthcare professionals manage the complexities of RRS in daily practice as well as identifying its challenges. Methods We observed RRS through in situ simulations in 2 wards and conducted the debriefings as focus group interviews. By arranging a separate focus group interview, we included the perspectives of intensive care unit personnel. Results Healthcare professionals appreciated the standardized use of the National Early Warning Score, when combined with clinical knowledge and experience, structured communication, and interprofessional collaboration. However, we identified salient challenges in RRS, for example, unwanted variation in recognition competence, and inconsistent routines in education and documentation. Furthermore, we found that a lack of interprofessional trust, different understandings of RRS protocol, and signs of low psychological safety in the wards disrupted collaboration. To help remedy identified challenges, healthcare professionals requested shared arenas for learning, such as in situ simulation training. Conclusions Through system probing, we described the inner workings of RRS and revealed the challenges that require more attention. Healthcare professionals depend on structured RRS education, training, and resources to operate such a system. In this study, they request interventions like in situ simulation training as an interprofessional educational arena to improve patient care. This is a relevant field for further research. The Consolidated Criteria for Reporting Qualitative Studies Checklist was followed to ensure rigor in the study.publishedVersio

Decay in chest compression quality due to fatigue is rare during prolonged advanced life support in a manikin model

<p>Abstract</p> <p>Background</p> <p>The aim of this study was to measure chest compression decay during simulated advanced life support (ALS) in a cardiac arrest manikin model.</p> <p>Methods</p> <p>19 paramedic teams, each consisting of three paramedics, performed ALS for 12 minutes with the same paramedic providing all chest compressions. The patient was a resuscitation manikin found in ventricular fibrillation (VF). The first shock terminated the VF and the patient remained in pulseless electrical activity (PEA) throughout the scenario. Average chest compression depth and rate was measured each minute for 12 minutes and divided into three groups based on chest compression quality; good (compression depth ≥ 40 mm, compression rate 100-120/minute for each minute of CPR), bad (initial compression depth < 40 mm, initial compression rate < 100 or > 120/minute) or decay (change from good to bad during the 12 minutes). Changes in no-flow ratio (NFR, defined as the time without chest compressions divided by the total time of the ALS scenario) over time was also measured.</p> <p>Results</p> <p>Based on compression depth, 5 (26%), 9 (47%) and 5 (26%) were good, bad and with decay, respectively. Only one paramedic experienced decay within the first two minutes. Based on compression rate, 6 (32%), 6 (32%) and 7 (37%) were good, bad and with decay, respectively. NFR was 22% in both the 1-3 and 4-6 minute periods, respectively, but decreased to 14% in the 7-9 minute period (P = 0.002) and to 10% in the 10-12 minute period (P < 0.001).</p> <p>Conclusions</p> <p>In this simulated cardiac arrest manikin study, only half of the providers achieved guideline recommended compression depth during prolonged ALS. Large inter-individual differences in chest compression quality were already present from the initiation of CPR. Chest compression decay and thereby fatigue within the first two minutes was rare.</p

Reducing unwarranted variation: can a ‘clinical dashboard’ be helpful for hospital executive boards and top-level leaders?

Background/aim: In the past decades, there has been an increasing focus on defining, identifying and reducing unwarranted variation in clinical practice. There have been several attempts to monitor and reduce unwarranted variation, but the experience so far is that these initiatives have failed to reach their goals. In this article, we present the initial process of developing a safety, quality and utilisation rate dashboard (‘clinical dashboard’) based on a selection of data routinely reported to executive boards and top-level leaders in Norwegian specialist healthcare. Methods: We used a modified version of Wennberg’s categorisation of healthcare delivery to develop the dashboard, focusing on variation in (1) effective care and patient safety and (2) preference-sensitive and supply-sensitive care. Results: Effective care and patient safety are monitored with outcome measures such as 30-day mortality after hospital admission and 5-year cancer survival, whereas utilisation rates for procedures selected on cost and volume are used to follow variations in preference-sensitive and supply-sensitive care. Conclusion: We argue that selecting quality indicators of patient safety, quality and utilisation rates and presenting them in a dashboard may help executive hospital boards and top-level leaders to focus on unwarranted variation

Reactions and coping strategies in lay rescuers who have provided CPR to out-of-hospital cardiac arrest victims: A qualitative study

Objective: Cardiopulmonary resuscitation (CPR) provided by community citizens is of paramount importance for out-of-hospital cardiac arrest (OHCA) victims’ survival. Fortunately, CPR rates by community citizens seem to be rising. However, the experience of providing CPR is rarely investigated. The aim of this study was to explore reactions and coping strategies in lay rescuers who have provided CPR to OHCA victims. Methods, participants: This is a qualitative study of 20 lay rescuers who have provided CPR to 18 OHCA victims. We used a semistructured interview guide focusing on their experiences after providing CPR. Setting: The study was conducted in the Stavanger region of Norway, an area with very high bystander CPR rates. Results: Three themes emerged from the interview analysis: concern, uncertainty and coping strategies. Providing CPR had been emotionally challenging for all lay rescuers and, for some, had consequences in terms of family and work life. Several lay rescuers experienced persistent mental recurrences of the OHCA incident and had concerns about the outcome for the cardiac arrest victim. Unknown or fatal outcomes often caused feelings of guilt and were particularly difficult to handle. Several reported the need to be acknowledged for their CPR attempts. Health-educated lay rescuers seemed to be less affected than others. A common coping strategy was confiding in close relations, preferably the health educated. However, some required professional help to cope with the OHCA incident. Conclusions: Lay rescuers experience emotional and social challenges, and some struggle to cope in life after providing CPR in OHCA incidents. Experiencing a positive patient outcome and being a health-educated lay rescuer seem to mitigate concerns. Common coping strategies are attempts to reduce uncertainty towards patient outcome and own CPR quality. Further studies are needed to determine whether an organised professional follow-up can mitigate the concerns and uncertainty of lay rescuers.publishedVersio
