- A two-tiered ambulance system with a mobile coronary care unit and standard ambulance has operated in Gothenburg (population 434,000) since 1980. Mass education in cardiopulmonary resuscitation (CPR) commenced in 1985 and in 1988 semiautomatic defibrillators were introduced. Aim: To describe early and late survival after cardiac arrest outside hospital over a 12-year period. Target population: All patients with prehospital cardiac arrest in Gothenburg reached by mobile coronary care unit or standard ambulance between 1980 and 1992.

- Since 1980 an Emergency Medical Service (EMS) system with a two-tier ambulance service has been operating in Göteborg. During this 12-year period, all cardiac arrests outside hospital have been monitored. Cardiopulmonary resuscitation (CPR) training for the general public began in 1985 and, by the end of 1992, 125 000 persons had been trained. The aim of this study was to define the factors associated with an increased chance of survival after cardiac arrest witnessed out-of-hospital and secondary to ventricular fibrillation. The study group comprises all patients with cardiac arrest witnessed outside hospital in Göteborg between 1980 and 1992, in whom CPR was initiated by our EMS and ventricular fibrillation observed at the first ECG recording. In a multivariate analysis of age, sex, time of collapse, interval between collapse and first defibrillation, bystander-initiated CPR, the following factors were associated with an increased chance of being discharged from hospital: (1) Short interval between collapse and first defibrillation (P < 0.001); (2) Bystander-initiated CPR (P < 0.001); and (3) Age (P < 0.05). Among patients with an out-of-hospital cardiac arrest who were found by the EMS personnel to have ventricular fibrillation, the predictors of survival were: interval between collapse and defibrillation, bystander-initiated CPR and age.

- A media campaign conducted to reduce delay time and to increase the use of ambulance transport in acute myocardial infarction was performed in an urban area with about half a million inhabitants during 1 year. The main message was that chest pain lasting more than 15 minutes might indicate acute myocardial infarction; dial 90,000 immediately for ambulance transport to the hospital. The target population was the general public. After 6 and 12 months 400 and 610 randomly chosen persons, respectively, were contacted by telephone to evaluate the reaction of the general public to the campaign. Of these, 60% and 71%, respectively, had heard of the campaign, and all parts of the message were spontaneously remembered by 15% and 19%, respectively. The reaction to the campaign was generally positive. Among all patients admitted to the coronary care unit of one of the two city hospitals, 65% were aware of the campaign and 31% of them were of the opinion that they came to the hospital faster because of the campaign. In conclusion, a media campaign aimed at reducing patient delay time in acute myocardial infarction was shown to reach a majority of people in the community and patients with ischemic heart disease. The reaction was positive and about one fifth of interviewed people spontaneously remembered the total message.

- Background: A two-tiered ambulance system with a mobile coronary care unit and standard ambulance has operated in Gothenburg (population 434 000) since 1980. Mass education in cardiopulmonary resuscitation (CPR) commenced in 1985 and in 1988 semiautomatic defibrillators were introduced. Aim: To describe early and late survival after cardiac arrest outside hospital over a 12-year period. Target population: All patients with prehospital cardiac arrest in Gothenburg reached by mobile coronary care unit or standard ambulance between 1980 and 1992. Results: The number of patients with cardiac arrest remained fairly steady over time. Among patients with witnessed ventricular fibrillation, the time to defibrillation decreased over time. The proportion of patients in whom bystander initiated CPR was increased only moderately over time. The proportion of patients given medication such as lignocaine and adrenaline successively increased. The number of patients with cardiac arrest who were discharged from hospital per year remained steady between 1981 and 1990 (20 per year), but increased during 1991 and 1992 to 41 and 31 respectively. Conclusions: Improvements in the emergency medical service in Gothenburg over a 12-year period have lead to: (1) a shortened delay time between cardiac arrest and first defibrillation and (2) an improved survival of patients with cardiac arrest outside hospital probably explained by this shortened delay time.

Effect of bystander initiated cardiopulmonary resuscitation on ventricular fibrillation and survival after witnessed cardiac arrest outside hospital

- OBJECTIVE--To describe the proportion of patients who were discharged from hospital after witnessed cardiac arrest outside hospital in relation to whether a bystander initiated cardiopulmonary resuscitation. PATIENTS--All patients with witnessed cardiac arrest outside hospital before arrival of the ambulance and in whom cardiopulmonary resuscitation was attempted by the emergency medical service in Gothenburg during 1980-92. RESULTS--Cardiopulmonary resuscitation was initiated by a bystander in 18% (303) of 1,660 cases. In this group 69% had ventricular fibrillation at first recording compared with 51% in the remaining patients (P < 0.001). Among patients in whom cardiopulmonary resuscitation had been initiated by a bystander 25% were discharged alive versus 8% of the remaining patients (P < 0.001). Independent predictors of survival were in order of significance: initial arrhythmia (P < 0.001), interval between collapse and arrival of first ambulance (P < 0.001), cardiopulmonary resuscitation initiated by a bystander (P < 0.001), and age (P < 0.01). Among patients who were admitted to hospital alive 30% of patients in whom cardiopulmonary resuscitation had been initiated by a bystander compared with 58% of remaining patients (P < 0.001) had brain damage and died in hospital. Corresponding figures for death in association with myocardial damage were 18% and 29% respectively (P < 0.01). CONCLUSIONS--Cardiopulmonary resuscitation initiated by a bystander maintains ventricular fibrillation and triples the chance of surviving a cardiac arrest outside hospital. Furthermore, it seems to protect against death in association with brain damage as well as with myocardial damage.

- We evaluated the effect of a media campaign aimed at reducing delay times in suspected acute myocardial infarction (AMI) on the volume of chest pain patients seen in the emergency department. During the 1st week of the campaign, the mean number of chest pain patients increased from 10.5 per day prior to the start to 25.4. However, the number declined rapidly in subsequent months. The greatest increase was observed in patients with chest pain in whom AMI was not suspected on examination. During the campaign, 4,805 patients with chest pain appeared in the emergency department as compared with 4,407 patients during the same time period prior to its start, an increase of 9%. The number of patients with confirmed AMI increased from 595 to 629 (6%).
