Investigating the Success Rate of Cardiopulmonary Resuscitation, Survival Rate in Patients,and their Related Factor

Abstract

Background: Cardiopulmonary resuscitation (CPR) procedure consists of measures taken to restore the acts of the heart and the brain in a person who has lost their own consciousness. Thus, the purpose of the present study was to investigate the success rate of Cardiopulmonary Resuscitation, survival rate in patients, and their related factors in order to assist in improving effective conditions and measures within hospitals to increase the success rate of CPR. Methods: This cross-sectional analytic study was conducted in 2016. To this end, a total number of 199 patients affected with cardiopulmonary arrest and undergoing the CPR procedure in the emergency wards and other hospitals units in Iran were recruited using a convenience sampling method. Then, patient information was collected through a researcher-designed checklist as well as a review of clinical records. The data were also analyzed via the SPSS.16 software. Data analysis was similarly performed using descriptive statistics and Chi-square and t-test. Results: The mean age of patients was 44 years. The result of 36.7% of CPR procedures conducted was reported successful, however, only 4% of patients finally survived. In general, the findings revealed that factors such as age, gender, hospital, history of prior diseases, checked initial rhythm, work shift, time of work shift change, pre-resuscitation intubation status, and underlying cause of cardiopulmonary arrest had no effects on the success rate of CPR procedure. However, location of the occurrence of cardiopulmonary arrest (P = 0.03) and specialty of physicians in charge of resuscitation teams (P = 0.01) were among the factors affecting the success rate of CPR procedure. Furthermore, checked initial cardiac rhythm (P < 0.0001) and a history of prior heart diseases (P = 0.05) in patients had impacts on their survival rate. Conclusions: Given the simplicity and teachability of the principles of basic life support (BLS), health status, and survival rate in patients can be easily and significantly promoted through the public education of the initial resuscitation measures. Moreover, according to the investigations made in this respect, post-resuscitation measures can dramatically affect the survival rate of individuals. Therefore, it is suggested to investigate post-resuscitation measures in other studies of prospective type in order to propose strategies to improve the survival rate of patients.
