a prospective study of survival after in-hospital cardiopulmonary resuscitation and its related factors

conclusions the survival rate after in-hospital cpr was very low. the duration of cpr and the time of initiating cpr effects patients’ outcomes. these findings highlight the crucial role of an organized, skilled, well-established and timely cpr team. background despite several studies, there is no agreement on factors that affect survival after in-hospital cardiopulmonary resuscitation (cpr). objectives this study aimed to evaluate the survival rate of in-hospital cpr and its related factors at shahid beheshti hospital in kashan, iran, in 2014. patients and methods a descriptive study was conducted on all cases of cpr performed in kashan shahid beheshti hospital during a 6-month period in 2014. through a consecutive sampling method, 250 cases of cpr were studied. a three-part researcher-made instrument was used. the outcome of cpr was documented as either survival to hospital discharge or unsuccessful (death of the patient). chi-square test, t test, and logistic regression analysis were used to analyze the data. results of all cpr cases, 238 (95.2%) were unsuccessful and 12 (4.8%) survived to hospital discharge. only 2.6% of patients who were resuscitated in medical units survived to hospital discharge, whereas this rate was 11.4% in the emergency department. only 45 (18%) patients were defibrillated during resuscitation; in 11 patients, defibrillation was performed between 15 to 45 minutes after the initiation of cpr. the mean time from initiation of cpr to the first dc shock was 13.93 ± 8.88 minutes. moreover, the mean duration of cpr was 35.11 ± 11.42 minutes. the survival rate was higher in the morning shift and lower during the time of shift change (9.4% vs. 0). the duration of cpr and speed of arrival of the cpr team were identified as factors that predicted the outcome of cpr.
