In-hospital cardiopulmonary resuscitation - 5 years' incidence and survival according to the Utstein template

Background: Direct comparison of survival rates from in-hospital cardiopulmonary resuscitation (CPR) remains difficult. The objective of this study was to report outcome according to the Utstein template for in-hospital cardiac arrest and to evaluate the Utstein template itself as applied to a retrospective material. Methods: The hospital (900 beds, 37 000 annual admissions) has no established do-not-resuscitate (DNR) order policy. CPR outside the Intensive- or Coronary Care Units (ICU/CCU) is performed by an emergency medical team consisting of an anaesthesiologist, a medical resident and a nurse anaesthetist. CPR attempts during 5 years (1990-1994) were analysed retrospectively. Patient survival, cerebral and overall performance category (CPC/OPC) score of the survivors was determined. The Utstein template was evaluated in terms of clinical relevance and data availability. Results: During 5 years, 4927 patients died as in-patients. CPR outside the CCU/ICU was attempted 244 times. CPR was primarily successful on 83 occasions (34%), and 42 patients (17%) were finally discharged with CPC 1 or 2. Survival from primary ventricular fibrillation (VF) or ventricular tachycardia was 40%, pulseless electrical activity 3%, asystole 11% and of rhythm undetermined 6%. Age or sex effects were not observed. Conclusion: More than 90% of in-hospital deaths in this hospital are handled without CPR being initiated. Overall survival was 17%, and almost all survivors made a favourable outcome. The Utstein template for in-hospital cardiac arrest performed acceptably as a framework for reporting outcome in this retrospective study.
