About this study
Official title: Ten-year Trends in the Pre-hospital Emergency Care Spectrum in Beijing From 2005 to 2014: A Multicenter, Retrospective, Observational Study
This was a retrospective analysis of a cohort of all emergency care patients in Beijing from January 2005 to December 2014. This aim of this study was to analyze the trends in pre-hospital emergency care need and the emergency response times, with the intention of aiding the government to optimize medical resources and improve pre-hospital emergency care.
Read the detailed description
Pre-hospital emergency care is a very important part of Emergency Medical Service (EMS) System, crucial to patients' life support, disability and mortality rate reduction. The level of pre-hospital emergency care reflects the comprehensive ability of the organizational, management and public welfare of a country. Beijing Emergency Center and Beijing Red Cross Emergency Center are in the charge of all the pre-hospital emergency care in Beijing, which respectively subordinate to Beijing government and Chinese Red Cross Society. This study collected the data of 3,909,746 cases from these two pre-hospital care centers from January, 2005 to December, 2014 and retrospective analyzed the pre-hospital emergency call demand and first aid related time. The results of this study can help the government optimize medical resources; strengthen the prevention of related emergency diseases. The changes and trends of pre-hospital care disease spectrum also present the same problems and situation of developing megacities like Beijing. Based on the meticulous work in these 2 centers, this study has collected the most complete pre-hospital emergency care data in China.

| Study group | Role | What they receive |
|---|---|---|
| Prehospital care | All pre-hospital service data were collected from January 2005 to December 2014 from the Beijing Emergency Center and Beijing Red Cross Emergency Center, which oversee all pre-hospital care in Beijing. The major illnesses were classified into 34 disease spectrum categories according to the Medical Priority Dispatch System (MPDS) which total includes 34 diseases. Data on pre-hospital emergency demand and first aid-related time intervals were analyzed to determine trends over the period. Receives: Procedure: Prehospital care |
What is being measured
The primary outcome is the main question the study is designed to answer.
Cause of the emergency
The chief complaints of the patients were classified into 34 illnesses according to the Medical Priority Dispatch System (MPDS) which total includes 34 diseases.
Measured: 10 years
Secondary outcomes (2)
The pre-hospital emergency call demand
Total number of pre-hospital emergency calls, reduces the number of missing record, records with no identifiable chief complaint, repeated data, not-emergency care.
Measured: 10 years
Emergency care-related time
Emergency care-related time included emergency response time (ERT), active response time (ART), and passive response time (PRT). ART was defined as the time from emergency call to ambulance departure time; PRT was from departure time to arrival time at the pre-hospital center; ERT was the time from the emergency call to arrival time.
Measured: 10 years
