Baseline Investigation of Patients With Cardiac Arrest in China

Study Overview
=================
Brief Summary
-----------------
BASIC is a perspective, multicentre and large-scale registry focusing on of patients suffering a cardiac arrest in China. The aims of the study are to establish the monitoring sites covering out-of-hospital cardiac arrest (OHCA) and in-hospital cardiac arrest (IHCA) in urban and rural areas in 7 regions (East China, North China, South China, Central China, Northeast China, Southwest China and Northwest China) around China, to collect data from cardiac arrest patients, and to describe basic characteristics, treatments, outcomes, incidences and risk factors of OHCA and IHCA in China.

Baseline Investigation of Patients With Cardiac Arrest in China

Conditions

Cardiac Arrest

Participation Criteria
=================
Eligibility Criteria
-----------------
Inclusion Criteria: OHCA: Every patient who suffered a cardiac arrest that occurred in any location other than a hospital, and was attended and/or treated by an EMS. IHCA: Every patient who suffered a cardiac arrest in hospital. the representative population-based survey: Every patient who suffered a cardiac arrest in the selected cities or suburbs. Exclusion Criteria: OHCA: 1)The out-of-hospital cardiac arrest patients who were taken to the hospital by their family members; 2) Bystanders suspected cardiac arrest, but the ROSC was achieved without defibrillation or resuscitation by EMS. IHCA: The patient who suffered a cardiac arrest that occurred out-of-hospital and then transferred to the hospital.
