- BACKGROUND AND AIM: Sudden cardiac arrest survivors suffer from ischaemic brain injury that may lead to poor neurological outcome and death. The reperfusion injury that occurs is associated with damaging biochemical reactions, which are suppressed by mild therapeutic hypothermia (MTH). In several studies MTH has been proven to be safe, with few complications and improved survival, and is recommended by the International Liaison of Committee on Resuscitation. The aim of this paper is to recommend clinical practice guidelines for MTH treatment after cardiac arrest from the Scandinavian Society of Anaesthesiology and Intensive Care Medicine (SSAI). METHODS: Relevant studies were identified after two consensus meetings of the SSAI Task Force on Therapeutic Hypothermia (SSAITFTH) and via literature search of the Cochrane Central Register of Controlled Trials and Medline. Evidence was assessed and consensus opinion was used when high-grade evidence (Grade of Recommendation, GOR) was unavailable. A management strategy was developed as a consensus from the evidence and the protocols in the participating countries. RESULTS AND CONCLUSION: Although proven beneficial only for patients with initial ventricular fibrillation (GOR A), the SSAITFTH also recommend MTH after restored spontaneous circulation, if active treatment is chosen, in patients with initial pulseless electrical activity and asystole (GOR D). Normal ethical considerations, premorbid status, total anoxia time and general condition should decide whether active treatment is required or not. MTH should be part of a standardized treatment protocol, and initiated as early as possible after indication and treatment have been decided (GOR E). There is insufficient evidence to make definitive recommendations among techniques to induce MTH, and we do not know the optimal target temperature, duration of cooling and rewarming time. New studies are needed to address the question as to how MTH affects, for example, prognostic factors.

- During disasters, especially earthquakes, health systems are expected to play an essential role in reducing mortality and morbidity. The most significant naturally occurring disaster in Iran is earthquakes; they have killed >180,000 people in the last 90 years. According to the current plan in 2007, the disaster management system of Iran is composed of three main work groups: (1) Prevention and risk management, (2) Education, and (3) Operation. This organizational separation has resulted in lack of necessary training programs for experts of specialized organizations, e.g., the Ministry of Health and Medical Education (MOHME). The National Board of MOHME arranged a training program in the field of medical disaster management. A qualified training team was chosen to conduct this program in each collaborating center, based on a predefined schedule. All collaborating centers were asked to recall 5–7 experts from each member university. Working in medical disaster management field for ≥2 years was an inclusion criterion. The training programs lasted three days, consisted of all relevant aspects of medical disaster management, and were conducted over a six-month period (November 2007–April 2008). Pretest and post-tests were used to examine the participants’ knowledge regarding disaster management; the mean score on the pre-test was 67.1 ±11.6 and 88.1 ±6.2, respectively. All participants were asked to hold the same training course for their organizations in order to enhance knowledge of related managers, stakeholders, and workers, and build capacity at the local and provincial levels. The next step was supposed to be developing a comprehensive medical disaster management plan in the entire country. Establishing nine disaster management regional collaborating centers in the health system of Iran has provided an appropriate base for related programs to be rapidly and easily accomplished throughout the country. This tree-shaped model is recommended as a cost-benefit and rapid approach for conducting training programs and developing a disaster management plan in the health system of a developing country.

Journal article (peer-reviewed)abstract
- INTRODUCTION: Construction of an effective in-hospital resuscitation programme is challenging. To document and analyse resuscitation skills assessment must provide reliable data. Benchmarking with a hospital having documented excellent results of in-hospital resuscitation is beneficial. The purpose of this study was to assess the resuscitation skills to facilitate construction of an educational programme. MATERIALS AND METHODS: Nurses working in a university hospital Jorvi, Espoo (n=110), Finland and Sahlgrenska University Hospital, Goteborg (n=40), Sweden were compared. The nurses were trained in the same way in both hospitals except for the defining and teaching of leadership applied in Sahlgrenska. Jorvi nurses are not trained to be, nor do they act as, leaders in a resuscitation situation. Their cardiopulmonary resuscitation (CPR) skills using an automated external defibrillator (AED) were assessed using Objective Structured Clinical Examination (OSCE) which was build up as a case of cardiac arrest with ventricular fibrillation (VF) as the initial rhythm. The subjects were tested in pairs, each pair alone. Group-working skills were registered. RESULTS: All Sahlgrenska nurses, but only 49% of Jorvi nurses, were able to defibrillate. Seventy percent of the nurses working in the Sahlgrenska hospital (mean score 35/49) and 27% of the nurses in Jorvi (mean score 26/49) would have passed the OSCE test. Statistically significant differences were found in activating the alarm (P<0.001), activating the AED without delay (P<0.01), setting the lower defibrillation electrode correctly (P<0.001) and using the correct resuscitation technique (P<0.05). The group-working skills of Sahlgrenska nurses were also significantly better than those of Jorvi nurses. CONCLUSIONS: Assessment of CPR-D skills gave valuable information for further education in both hospitals. Defining and teaching leadership seems to improve resuscitation performance.

Journal article (peer-reviewed)abstract
- OBJECTIVES: The objective of the study was to assess the effect of protocol compliance to the accuracy of cardiac arrest (CA) identification by the dispatchers. METHODS: The study was conducted prospectively over a 1-year period in 1996. The calls categorized as non-traumatic CAs by the dispatcher and calls where the patient was in non-traumatic CA when ambulance crew arrived were included in the study. The data was collected from emergency call tape recordings and ambulance run sheets. The compliance to the protocol was defined as gathering information to two questions: (1) Is the patient awake or can she/he be awakened? and (2) Is she/he breathing normally? RESULTS: The number of calls included in the study was 776 and the dispatchers identified 83% of the CAs. The protocol was adhered in 52.4% of calls, more often in witnessed than unwitnessed cases (72.3% versus 45.0%, P<0.001). In correctly identified CAs, the protocol compliance was 49.4%. The compliance was higher in cases of unidentified CAs (60.3%, P=0.0326) and in cases of wrongly identified as CAs (false positives, 61.9%, P=0.0276). CONCLUSIONS: A high identification rate of CAs seems to be achievable despite poor protocol compliance by dispatchers.

Disaster medicine- performance indicators, information support and documentation : A study of an evaluation tool
- 2006
-
Doctoral thesis (other academic/artistic)abstract
- The science of disaster medicine is more a descriptive than analytical type. Research, in most instances, has not employed quantitative methods and there is very sparse knowledge based on analytical statistics. One consequence of this is that similar mistakes are repeated over and over. Lessons that should be learned are merely observed.Moreover, there are almost no practical or ethical ways in which randomised controlled studies can be performed.The management, command and control of situations on different levels of hierarchy has eldom been evaluated and there have been no standards against which performance can be evaluated. Furthermore, the documentation of decisions and staff work is rarely sufficient enough to evaluate command and control functions.Setting standards that may be used as templates for evaluation and research is an issue that is constantly being addressed by leading experts in the field of disaster medicine and this is also an important issue that is expressed in the Utstein Template.Swedish National Board of Health and Welfare, templates of performance indicators were developed. These were tested on reports available from incidents, and our conclusion was that documentation in this form was not adequate enough for use in this method of evaluation.Documentation must be improved and data probably need to be captured and stored with the help of information systems.A template developed for the evaluation of medical command and control at the scene was tested in standardised examinations. When using this template in this setting it was possible to obtain specific information on those aspects of command and control that need to be improved.An information system using on-line Internet technique was studied twice. The first study concluded that in spite of technical disturbances the system was acceptable to the organisation but could not yet be recommended for use during major incidents. The second study concluded that the retrieval of information was, in all respects not as good as the control system, a conventional ambulance file system.In a study of staff procedure skills during training of management staffs in command and control it was concluded that documentation during training sessions was not adequate and this lack of staff procedure skills could possibly be a contributing factor to the fact that lessons in command and control are not learned from incidents.Conclusions in thesis are that measurable performance indicators can be used in the training of command and control. If performance indicators are to be used in real incidents and disasters, functioning information systems have to be developed. This may lead to a better knowledge of command and control and could possibly contribute to a process where lessons are learned and mistakes are not repeated.

Presenting complaint and mortality in non-surgical emergency medicine patients
- 2008
-
Doctoral thesis (other academic/artistic)abstract
- In 1995 and 2000 a total of 29 886 non surgical ED visits at Uppsala University Hospital were registered. Presenting complaint, admittance to a ward, length of stay, in-hospital mortality, discharge diagnoses, 30-day and long-term mortality were registered. The presenting complaints were sorted into 33 presenting complaint groups (PCGs). For different PCGs there was different in-hospital fatality rate. Compared to the largest PCG, chest pain, the gender and age adjusted OR was 2.12 (95% CI 1.01 – 4.44) for the miscellaneous complaint group and 2.04 (95 % CI 1.35 – 3.08) for the stroke–like symptom group. Within a given PCG the in-hospital mortality could vary depending on discharge diagnoses. By relating PCG and long term mortality to the expected mortality in the population, the Standardized Mortality Ratio (SMR) could be calculated. The SMR was found to be highest in seizure 2.62 (95 % CI 2.13 – 3.22), intoxication 2.51 (95% CI 2.11-2.98) and symptoms of asthma 1.8 (1.65 – 2.06). For the same discharge diagnoses the long term mortality could differ considerably depending on PCG at ED arrival (p<0.001). Between 1995 and 2000 there was a 30 % increase in ED visits at the non surgical ED. PCGs representing lesser severe conditions had increased. Demographic changes could account for 45 % of the increment and the remaining increase could be ascribed to change in visiting pattern. In the 2000 cohort 41.0 % of all visits were performed by re-visitors. The number of revisits and five-year mortality had an inversed u-shaped relationship were patients with three re-visits within the same year had an increased mortality compared to patients with more or less visits. Conclusion: It is possible to define presenting complaint groups (PCGs) that are robust and consistent over time and useful as a tool for epidemiological studies in the ED.
