- There are currently 1.5 million trained cardiopulmonary resuscitation (CPR) rescuers in Sweden. Bystander CPR is performed on ≈30% of out-of-hospital cardiac arrests. The aim of this study was to analyse trained CPR rescuers’ attitudes and beliefs in terms of CPR performance in an emergency and differences with regard to gender, age, residential area and occupation. In a nation wide survey 1410, randomly selected, recently trained CPR rescuers were approached with a postal questionnaire, resulting in 1012 respondents. The mean age was 36.9 years and only 3% of the respondents were >59 years old. Only 1% had attended the course because of their own or a relative’s cardiac disease. Ninety-four per cent believed there was a minor to major risk of serious disease transmission while performing CPR. When predicting their willingness to perform CPR in six scenarios, 17% would not start CPR on a young drug addict, 7% would not perform CPR on an unkempt man, while 97% were sure about starting CPR on a relative and 91% on a known person. In four of six scenarios, respondents from rural areas were significantly more positive than respondents from metropolitan areas about starting CPR. In conclusion, readiness to perform CPR on a known person is high among trained CPR rescuers, while hesitation about performing CPR on a stranger is evident. Respondents from rural areas are more frequently positive about starting CPR than those from metropolitan areas.

- The importance of bystander cardiopulmonary resuscitation (CPR) prior to arrival of the emergency medical service is well documented. In Sweden, CPR is initiated prior to emergency medical services (EMS) arrival in about 30% of cardiac arrests out-of-hospital, a figure which should be improved urgently. To do so, it is of interest to know more about the bystanders' perceptions of their intervention. A qualitative method inspired by the phenomenographic approach was applied to 19 bystanders who had performed CPR. In the analysis, five main categories and 14 subcategories emerged. The main categories were: to have a sense of humanity, to have competence, to feel an obligation, to have courage and to feel exposed. Interviews described how humanity and concern for another human being were the foundation of their intervention. CPR training offers the possibility to give appropriate help in this emergency. If the aim of CPR training was extended beyond teaching the skill of CPR to include preparation of the rescuer for the intervention and his/her reactions, this might increase the number of people able to take action in the cardiac arrest situation.

- Objectives:To investigate how emergency medical dispatchers (EMDs) perceive their experience of identifying suspected cardiac arrests (CA), and offer and provide instructions in cardiopulmonary resuscitation via telephone (t-CPR). Design: A qualitative method using the phenomenographic design where 10 EMDs were approached for semi-structured interviews. Main outcome measures: Perception in identifying CA, perception in offering t-CPR and perception in providing t-CPR. Results: In this analysis, 12 categories and 31 subcategories emerged. The categories for perception in identifying CA were; to trust the witness's account, to be open-minded and to be organised. The categories for perception in offering t-CPR were: to feel prepared to connect with the witness on a mental level by being organised, flexible and supportive, to obtain a basis for assessments and to be observant for diverse obstacles in a situation. Finally, the categories for perception in providing t-CPR were: to feel engaged, to be supportive of the witness, to feel secure by recognising response-feedback from the witness, to observe external conditions with regard to the locality and technical complications, to be composed and adjust to the needs of the situation, to feel competent or to feel despair. Conclusions: By listening in an open-minded way, a vast amount of information can be collected. Using criteria-based dispatch (CBD) and their own resources, the possibilities and difficulties of the situation are analysed. The EMDs believe that they are being an empathic support, relieving the witness of the burden of responsibility, and connecting with them mentally to enable them to act at the scene. There are EMDs who feel competent and experienced in managing these cases, and other EMDs who feel insecure and despair. The choice between providing t-CPR and answering incoming calls is prioritised differently among EMDs. There is also a broad subjective assessment among EMDs of offering t-CPR, especially to persons over 70 years old whom they consider incapable of performing CPR. The competence of the EMDs in t-CPR is dependent on re-training and a feedback on patient outcome. Witnesses who are negative towards acting constitute a common problem. There are witnesses with physical impediments or psychologically not susceptible to suggestions. The EMD is also dependent on the knowledge and trustworthiness of the witness. Convincing answers from witnesses prompt a more secure feeling in the EMDs, just as lack of knowledge in the witness has a negative effect on the efforts.

- AIM: One of the objectives of this study was to assess the emergency medical dispatchers (EMDs) ability for the identification and prioritisation of cardiac arrest (CA) cases, and offering and achievements of dispatcher-assisted bystander cardiopulmonary resuscitation (CPR). The other objective was to give an account of the frequency of agonal respiration in cardiac arrest calls and the caller's descriptions of breathing. METHODS: Prospective study evaluating 100 tape recordings of the EMD calls of emergency medical service (EMS)-provided advanced life support- (ALS) cases, of out-of-hospital cardiac arrest. RESULTS: The quality of EMD-performed interviews was highly commended in 63% of cases, but insufficient or unapproved in the remaining 37%. The caller's state of mind was not a major problem for co-operation. Among the 100 cases, 24 were suspected to be unconscious and in respiratory arrest. A further 38 cases were presented as unconscious with abnormal breathing. In only 14 cases dispatcher-assisted bystander CPR was offered by the EMD, and in 11 of these it was attempted, and completed in eight. Only four of the cases were unconscious patients with abnormal breathing. The incidence of suspected agonal breathing was estimated to be approximately 30% and the descriptions were; difficulty, poorly, gasping, wheezing, impaired, occasional breathing. CONCLUSIONS: Among suspected cardiac arrest cases, EMDs offer CPR instruction to only a small fraction of callers. A major obstacle was the presentation of agonal breathing. Patients with a combination of unconsciousness and agonal breathing should be offered dispatcher-assisted CPR instruction. This might improve survival in out-of hospital cardiac arrest.

- Aim: By evaluating tape recordings of true cardiac arrest calls, to judge the dispatchers ability to (a) identify cases as suspected cardiac arrest (CA), (b) give the case the right priority, (c) identify CA cases suitable for dispatcher-assisted, telephone-guided cardiopulmonary resuscitation (T-CPR) and (d) accomplish T-CPR. Methods: Evaluation of 99 tape recordings of consecutive cases that had been admitted to the two city hospitals in Göteborg after out-of-hospital CA. Results: In 70% of the interviews, the dispatcher demonstrated impeccable behaviour with short, distinct questions, quickly resulting in a decision on how to handle the case. In 30%, serious criticism could be voiced as the dispatcher displayed very stressful behaviour, or omitted to ask important questions such as whether the patient was conscious and breathing. In 21%, the interviews indicated a clear opportunity to perform T-CPR. In another 10%, there was a possibility of performing T-CPR. Only in 8% was T-CPR actually accomplished. Conclusions: (1) In the majority of the interviews, the quality was very high, while in one-third, serious criticism could be voiced. (2) In our study, only one-third (95% confidence interval, 22–41) of CA cases were suitable for T-CPR, and T-CPR was performed in only 8% of the 99 cases. (3) To optimise the dispatcher ability to identify suspected CA and initiate T-CPR, both medical knowledge and practical training are needed, preferably with protocols for pre-arrival instructions.

- AIM: To describe the epidemiology for out of hospital cardiac arrest of a non-cardiac aetiology. PATIENTS: All patients suffering from out of hospital cardiac arrest in whom resuscitation efforts were attempted in the community of Göteborg between 1981 and 2000. METHODS: Between October 1, 1980 and October 1, 2000, all consecutive cases of cardiac arrest in which the emergency medical service (EMS) system responded and attempted resuscitation were reported and followed up to discharge from hospital. RESULTS: In all, 5415 patients participated in the evaluation. Among them 1360 arrests (25%) were judged to be of a non-cardiac aetiology. Among these 24% were caused by a surgical cause or accident, 20% by obstructive pulmonary disease, 13% by drug abuse and the remaining 43% by 'another cause'. Of the patients with out of hospital cardiac arrest of a non-cardiac aetiology 4.0% survived to discharge from hospital as compared with 10.1% of the patients with a cardiac aetiology (P<0.0001). In the various subgroups survival was highest in those with drug abuse (6.8%) and lowest in those with 'another cause' (4.2%). Cerebral performance categories (CPC) score at hospital discharge tended to be worse among survivors from an arrest of non-cardiac than cardiac aetiology. Patients with a cardiac arrest of a non-cardiac aetiology differed from the remaining patients by being younger, including more women, less frequently having a witnessed arrest and less frequently being found in ventricular fibrillation/tachycardia. When simultaneously considering age, sex, witnessed status, presence of bystander cardiopulmonary resuscitation (CPR) and initial arrhythmia, the aetiology (non-cardiac vs. cardiac aetiology) was not an independent predictor of survival. CONCLUSION: Among patients with out of hospital cardiac arrest in whom resuscitation was attempted 25% were judged to be of a non-cardiac aetiology. These patients had a lower survival than patients with a cardiac arrest of cardiac aetiology. However, this was mainly explained by a lower occurrence of ventricular fibrillation and witnessed cardiac arrest.

Tidskriftsartikel (refereegranskat)abstract
- Aims: To describe the epidemiology, resuscitation factors and prognosis among a consecutive population of patients suffering from out-of-hospital cardiac arrest (OHCA) where pulseless electrical activity (PEA) was the first arrhythmia recorded on emergency medical services (EMS) arrival. Methods: Analysis of data collected prospectively on all patients regardless of age succumbing to OHCA during 1980–1997 in the community of Gothenburg where EMS initiated resuscitative measures. Results: 4662 patients with OHCA were attended by the EMS during the study period. Of these, 1069 (23%) were judged as having PEA as the first recorded arrhythmia; 158 (15%) of these were admitted alive to hospital and 26 (2.4%) were discharged alive. Survivors to discharge had a significantly larger share of bystander cardiopulmonary resuscitation (CPR) (28 vs. 8%, P=0.008), significantly higher levels of consciousness (8% awake vs. 0%, P<0.001) and higher median systolic blood pressure (145 vs. 106 mmHg, P<0.001) on arrival at hospital. No patient with unwitnessed cardiac arrest and PEA over 80 years old survived. Conclusion: Survival among patients suffering from OHCA and PEA is poor, especially among the elderly unwitnessed cases and those who do not receive bystander CPR. The latter seems to be of utmost importance among these patients.

Tidskriftsartikel (refereegranskat)abstract
- AIM: To describe patient characteristics, hospital investigations and interventions and early mortality among patients being hospitalized after out-of-hospital cardiac arrest in two hospitals. SETTING: Municipality of Göteborg, Sweden. PATIENTS: All patients suffering an out-of-hospital cardiac arrest who were successfully resuscitated and admitted to hospital between 1 October 1980 and 31 December 1996. All patients were resuscitated by the same Emergency Medical Service and admitted alive to one of the two city hospitals in Göteborg. RESULTS: Of 579 patients admitted to Sahlgrenska Hospital, 253 (44%) were discharged alive and of 459 patients admitted to Ostra Hospital, 152 (33%) were discharged alive (P < 0.001). More patients in Sahlgrenska Hospital were still receiving cardiopulmonary resuscitation (CPR) treatment (P = 0.03), but patients in Ostra had a lower systolic blood pressure and higher heart rate on admission. A larger percentage of patients admitted to Sahlgrenska Hospital underwent coronary angiography (P < 0.001), electrophysiological testing (P < 0.001), Holter recording (P < 0.001), echocardiography (P = 0.004), percutaneous transluminal coronary angioplasty (PTCA, P = 0.009), implantation of automatic implantable cardioverter defibrillator (AICD, P = 0.03) and exercise stress tests (P = 0.003). Inhabitants in the catchment area of Ostra Hospital had a less favourable socio-economic profile. CONCLUSION: Survival after out-of-hospital cardiac arrest may be affected by the course of hospital management. Other variables that might influence survival are socio-economic factors and cardiorespiratory status on admission to hospital. Further investigation is called for as more patients are being hospitalised alive after out-of-hospital cardiac arrest.

- AIM: To describe the epidemiology of children and young adults suffering from out-of-hospital cardiac arrest. PATIENTS: All patients suffering from out-of-hospital cardiac arrest in whom, resuscitation efforts were attempted in the community of Göteborg between 1980 and 2000. METHODS: Between 31 October 1980 and 31 October 2000, all consecutive cases of cardiac arrest in which the emergency medical service (EMS) system responded and attempted resuscitation were reported and followed-up to discharge from hospital. RESULTS: Among 5505 cardiac arrests information on age was available in 5290 cases (96%). Of these 5290 cases 98 (2%) were children (age 0-17 years), 197 (4%) were young adults (age 18-35 years) and the remaining 4995 (94%) were adults (age >35 years). Children and young adults differed from adults by suffering from a witnessed arrest less frequently, being found by the ambulance crew in ventricular fibrillation/tachycardia less frequently and being judged as having an underlying cardiac aetiology less frequently. Of the children only 5% were discharged from hospital alive compared with 8% for young adults and 9% for adults. Among survivors the cerebral performance categories (CPC) score at discharge tended to differ with 38% of young adults registering a CPC score of 1 (no neurological deficit) compared with 52% among adults. CONCLUSION: Children and young adults suffering from out-of-hospital cardiac arrest differed from adults in terms of aetiology and observed initial arrhythmia. Children had a particularly bad outcome whereas young adults had a similar outcome as adults.

- It is difficult to assemble data from an previous termout-of-hospital cardiac arrestnext term since there is often lack of objective information. The true incidence of previous termsudden cardiacnext term death previous termout-of-hospitalnext term is not known since far from all of these patients are attended by emergency medical services. The incidence of previous termout-of-hospital cardiac arrestnext term increases with age and is more common among men. Among patients who die, the probability of having a fatal event outside previous termhospitalnext term decreases with age; i. e. younger patients tend to more often die unexpectedly and outside previous termhospital.next term Among the different initial arrhythmias, ventricular fibrillation is the most common among patients with previous termcardiacnext term aetiology. The true distribution of initial arrhythmias is not known since several minutes most often elapse between collapse and rhythm assessment. Most patients with previous termout-of-hospital cardiac arrestnext term have a previous termcardiacnext term aetiology. previous termOut-of-hospital cardiac arrestsnext term most frequently occur in the patient's home, but the prognosis is shown to be better when they occur in a public place. Witnessed previous termarrest,next term ventricular fibrillation as initial arrhythmia and cardiopulmonary resuscitation are important predictors for immediate survival. In the long-term perspective, previous termcardiac arrestnext term in connection with acute myocardial infarction, high left ventricular ejection fraction, moderate age, absence of other heart failure signs and no history of myocardial infarction promotes better prognosis. Still there is much to learn about time trends, the influence of patient characteristics, comorbidity and previous termhospitalnext term treatment among patients with prehospital previous termcardiac arrest.
