The relationship of CPR success and time of patient's referring to emergency department

Although nearly 50 years have been passed from the beginning of Cardio-Pulmonary Resuscitation (CPR), the survival rate is still poor. Previous researches indicate that different factors affect CPR. This study was carried out with the aim of determining the relationship between CPR and the time of referring to the emergency department. This retrospective correlation study was performed on patients referring to the emergency department of Alborz province Social Security hospitals from March 2009 till March 2011 and had undergone CPR. 558 files were selected by census method and the data were collected from files and supervisor notes by a form. Results were analyzed by Chi-square test and Spearman’s correlation coefficient using SPSS 15 software. Generally, 32% of CPR operations were successful and 68% had failed. Most CPRs were done at 9:00 p.m. and 3:00 a.m. and the least frequency was related to the early hours of morning. 25.5% of CPRs were done during the morning shift, 23.5% during the evening shift and 51% during the night shift. No significant difference was observed between CPR results and work shifts (p=0.513) and there was no significant relation between the CPR team’s shift change time and CPR results (p=0.462). There’s no relation between CPR results and referral time. Other aspects of CPR such as improving the skill of treatment staff, forming a professional CPR team and updating the knowledge and nursing and medical techniques should be considered in planning the reduction of unsuccessful CPRs.
