Abstract: Objective To construet the out-of hospital cardiac arrest (OHCA) database based on Utstein style for standardizing the ollection of data and evaluation of the efct of cardiopulmonary resuscitation,so as to ffctively improve the quality of cardiopulmonary resuscitation and the survival rate of OHCA patients. Methods Based on, AHA guidelines , European Resuscitation Council guidelines and OHCA databases , we collected OHCA emergency medical records from January 2012 to July 2017 in Pudong New Area and the OHCA database based on Utstein style was constructed with the use of MySQL software and under the guidance of E-R model as well as the third paradigm. The database table structure was determined by expert group meetings. Results The OHCA database was constructed based on Utstein style , which consisted of five modules , namely basic data table , cardiac arrest data table , resuscitation table , outcome table and important time table. The database had the functions of input , export , inquiry and management and included 16 122 medical records. It standardized the input and expression of OHCA data. It has clear structure ，detailed content and convenient operation , which can provide a template for the routine OHCA registration in Pre-hospital Emergency Center. Conclusion The OHCA database based on Utstein style establishes the OHCA data collection standard in line with the characteristics of our country and provides an accurate management platform of OHCA information. It is not only laying the foundation for the future accurate research of OHCA,but also provides a scientific basis for the formulation of policies related to OHCA treatment.
