Insights
Out-of-hospital cardiac arrest survival rates were low in Israel (7% discharged). Prompt cardiopulmonary resuscitation (CPR) and advanced cardiac life support are crucial for improving patient outcomes.
Area of Science:
- Emergency Medicine
- Cardiology
- Public Health
Background:
- Out-of-hospital cardiac arrest (OHCA) presents a significant public health challenge.
- Paramedic care is a critical intervention for OHCA patients.
Purpose of the Study:
- To analyze OHCA outcomes in Israel between 1984-1985.
- To identify factors influencing resuscitation success and hospital discharge rates.
Main Methods:
- Retrospective study of over 3,500 OHCA patients receiving paramedic care.
- Analysis of patient data, including arrest cause, location, bystander CPR, and time to advanced cardiac life support.
Main Results:
- Underlying heart disease caused 83% of OHCA cases.
- Overall hospital discharge rate was 7%, with significant variation (0-13%) across paramedic service areas.
- Factors associated with successful resuscitation included witnessed collapse, ventricular fibrillation, rapid CPR, advanced cardiac life support, public location, and bystander CPR.
Conclusions:
- Improving OHCA survival requires prompt bystander CPR and reduced time to advanced paramedic care.
- Standardizing and enhancing paramedic service delivery is essential to reduce geographical disparities in outcomes.
Abstract:
Out-of-hospital cardiac arrests were studied in Israel from 1984 to 1985. More than 3,500 patients in cardiac arrest received paramedic care. Eighty-three percent of cases were caused by underlying heart disease. Overall, 17% of patients with arrest caused by heart disease were admitted and 7% were discharged from the hospital. There was a wide variation in the percent discharged among the 15 paramedic service areas, ranging from 0% to 13%. Factors associated with successful resuscitation included witnessed collapse, rhythm of ventricular fibrillation, short interval from collapse to cardiopulmonary resuscitation (CPR) and delivery of advanced cardiac life support, collapse at public location, and bystander initiation of CPR. Improvements in survival are likely to result if CPR is more frequently and promptly initiated and the time to arrival of definitive paramedic care can be improved.
