Evaluation of Cardiopulmonary Resuscitation (CPR) for Patient Outcomes and their Predictors.

INTRODUCTION

Cardiac arrest continues to be a common cause of in-hospital deaths. Even small improvements in survival can translate into thousands of lives saved every year.

AIM

The aim of our prospective observational study was to elicit the outcomes and predictors of in-hospital cardiopulmonary resuscitation among adult patients.

SETTINGS AND DESIGN

All in-hospital adult patients (age >14) who suffered cardiac arrest & were attended by a Code Blue Team between 1(st) January 2012 & 30(th) April 2013 were part of the study.

MATERIALS AND METHODS

The cardiopulmonary resuscitation (CPR) was assessed in terms of: Response time, Presenting initial rhythm, Time to first defibrillation, Duration of CPR and Outcome (Return of spontaneous circulation (ROSC), Glasgow outcome scale (GOS) at discharge).

STATISTICAL ANALYSIS

Age, GOS and mean response time were analysed using t-test and ANOVA. Logistic regression was applied to determine the significance of the various factors in determining mortality.

RESULTS

ROSC was achieved in 44% of a total of 127 patients included in our study. Asystole/Pulseless electrical activity (PEA) was the most common presenting rhythm (87.5%). The survival to discharge was seen in 7.1% patients of whom only 3.9% patients had good neurological outcome. Regression and survival analysis depicted achievement of ROSC during CPR, absence of co-morbidities and shorter response time of code blue team as predictors of good outcome.

CONCLUSION

We found poor outcome of CPR after in-hospital cardiac arrest. This was mainly attributed to an initial presenting rhythm of Asystole/PEA in most cases and delayed response times.
