success rate of cardiopulmonary resuscitation and related factors in emer- gency department of a private hospital in mashhad

Background and aims: most deaths occur unpredictably and outside health care facilities; however, they could be prevented by cardiopulmonary resuscitation (cpr) technique. moreover, the success rate of this procedure is affected by many factors. therefore, this study aimed to evaluate cpr outcomes and determine the associated factors. materials and methods: this descriptive retrospective study was conducted in 2018 in a private hospital in mashhad. the study participants were selected through census, and all the patients who underwent cpr were included in the study. however, those who had signs of death and/ or those with incomplete medical records were excluded from the study. moreover, data were provided through the statistics, medical records, as well as quality improvement units. results: in this study, 394 medical records were evaluated, out of which 224 (56.9%) and 170 (43.1%) belonged to male and female patients, respectively. in total, 96 (24.4%) cases of successful and 298(75.6%) cases of unsuccessful cpr were recorded. it should be mentioned that there was a significant correlation between the patient’s age and successful cpr (p=0.011). conclusion: results of the study revealed that the success rate of cpr has a positive relationship with the younger age patients, shorter cpr duration, and the lack of a non-cardiac underlying disease.
