title: [Prognostic factors for in-hospital cardiopulmonary arrests. A review of 760 cases].
abstract: OBJECTIVE
  The aim of this study is to analyse in-hospital cardiopulmonary arrests (CA) that took place in conventional wards and evaluate their prognostic factors.
  
  
  METHODS
  Retrospective review of in-hospital CA which occurred in our hospital over a 9-year period. CA that took place in intensive care areas, emergency rooms and operating theatres were excluded from the study. The following data were collected: demographic data, cause and initial rhythm of CA, internal control data, time, place, methods and results after cardiopulmonary resuscitation (CPR) (recovery of spontaneous circulation, [ROSC], and survival at discharge [SAD]) and neurologic performance at discharge. Results were analysed with SPSS(®) v. 20 predictive analytics software.
  
  
  RESULTS
  Average age was 66.9±17.5 years; 63.5% male. CA team arrived in 1.75±0.74min on average, and the average length of CPR was 25.8±16.10min. First rhythm: a) shockable rhythms=22.1%; b) asystole=66.2%, and c) pulseless electrical activity=11.7%. ROSC=51% and SAD=24.8%. Factors associated with a better prognostic (P<.05): age, reason for hospital admission, patient's previous physical condition, principal cause of CA, number of defibrillations and average length of CPR.
  
  
  CONCLUSIONS
  Despite having studied several variables as prognostic factors for CA and some of them being statistically significant, early prediction for survival for an in-hospital CA remains uncertain. Our study suggests that applying rational organisational measures, 25% of in-hospital CA could be discharged from hospital in good condition, and therefore, these organisational and educational measures should be extended to large hospitals.
