[Evaluation of the effectiveness of an in-hospital cardiac alarm system].
OBJECTIVE



OBJECTIVE
Evaluate effectiveness of our cardiac arrest (CA) system.


OBJECTIVE
To know the clinical and demographical characteristics of patients who undergo cardiopulmonary resuscitation (CPR). To know the action time of the CA team, immediate survival, hospital discharge and at one year, cerebral functional category of cardiorespiratory arrest survivors.


METHODS
Retrospective descriptive study on CA received in the Hospital San Millan of Logoroño.


METHODS
In-hospital cardiac arrest adults except for those in the Intensive Care Unit (ICU) and Emergency Department.


METHODS
From January 1, 2003 to December 31, 2006. Survival study until December 31, 2007. Data was collected from the Utstein Style Registry of the in-hospital CPR. Descriptive statistic analysis and bivariant analysis was performed with the Chi2 test and odds ratio (OR).


RESULTS
CPR was performed in 90 patients. Average arrival time was 1 minute. Origin was non-cardiac 56%, cardiac 34.4%. Initial rhythm was non-shockable 76.7%, shockable 22.2%. Survival at hospital discharge: 20%. Cerebral Performance Category 1: 89%. Survival after one year 16.7%. Survival: cardiac etiology (P=0.05; OR 0.20; 95% CI 0.06-0.65). Initial rhythm shockable (P=0.0001; OR 0.18; 95% CI 0.05-0.56) CONCLUSIONS: Our CA system is effective. We achieve a survival and cerebral performance categories on hospital discharge that is similar to other studies although the rate of patients with shockable rhythm and cardiac etiology in our series is less than others published.
