title: Outcome of cardiac arrests in a Portuguese hospital--evaluation of a hospital cardiopulmonar resuscitation program at one year.
abstract: OBJECTIVE
  Evaluation of a hospital-wide resuscitation program at one year.
  
  
  METHODS
  All records of cardiac arrest calls were collected, logged in a database by the same operator, and analyzed. The cardiac arrest teams consist of a physician and a nurse with ALS (Advanced Life Support) training. Each team has a radio that is activated by a single emergency number. Only cardiac arrest calls were analyzed.
  
  
  RESULTS
  Between March 1999 and March 2000 there were 173 emergency team calls. Of these, 120 were cardiac arrest calls (90 in-hospital and 30 from the emergency room--out-of-hospital cardiac arrests). Of the 90 in-hospital cardiac arrests, 61% were male, and median age was 73 years. In 90% of the calls, basic life support (BLS) was started before the arrival of the cardiac arrest team. The immediate cause was cardiac in 39% of the patients. Initial rhythm was ventricular fibrillation in 8%, asystole in 60% and other rhythms in 24% of the patients. Thirty percent presented return of spontaneous circulation (ROSC). There were no differences between those in whom BLS was started before the arrival of the cardiac arrest team and those in whom BLS had not been started. Ten patients (11%) were discharged from hospital. Of the 30 out-of-hospital cardiac arrests, 70% were male, and median age was 69 years. In 97% BLS was started before the arrival of the cardiac arrest team. The immediate cause was cardiac in 30% of patients. Initial rhythm was ventricular fibrillation in 10%, asystole in 73% and other rhythms in 17% of the patients. ROSC was achieved in 27% of the patients. Three patients (10%) were discharged from hospital. There were no differences either in ROSC or in survival to hospital discharge between in-hospital and out-of-hospital cardiac arrests. The state of health previous to cardiac arrest was significantly different between in- and out-of-hospital cardiac arrests: 3% versus 32% healthy, with no functional limitation. The authors conclude that: first, the current records do not enable all the desired goals of the "Utstein style" to be achieved and need to be reviewed; second, 90 to 97% of BLS previous to the arrival of the cardiac arrest team is a good indication of the efficiency of the hospital-wide program, which included training in BLS for all the hospital staff; third, the survival rate, although in accordance with much of the literature, could be improved.
