Shock in China 2018 (SIC-study): a cross-sectional survey

Area of Science:

• Critical care medicine
• Epidemiology
• Health services research

Background:

• Shock represents a life-threatening critical illness with significant patient mortality.
• Understanding the epidemiology and mortality of shock is crucial for improving patient outcomes.
• Identifying factors associated with hospital death in shock patients is essential for targeted interventions.

Purpose of the Study:

• To elucidate the epidemiology of shock in China.
• To determine the mortality rates associated with different types of shock.
• To identify key factors contributing to in-hospital mortality among shock patients.

Main Methods:

• A multi-center, cross-sectional survey was conducted across 1,064 tertiary hospitals in China.
• Data from 289,428 patients diagnosed with shock (ICD-10) were extracted from the Hospital Quality Monitoring System (HQMS) in 2018.
• Regression analysis was employed to identify factors associated with hospital death.

Main Results:

• Hypovolemic shock (44.38%) and septic shock (41.99%) were the most prevalent types.
• Cardiogenic shock exhibited the highest in-hospital mortality rate (31.6%), followed by obstructive (25.2%), septic (22.9%), and hypovolemic shock (15.5%).
• The presence of malignant tumors was identified as a significant factor related to hospital deaths in shock patients.

Conclusions:

• Shock is a severe condition characterized by high fatality rates and substantial clinical costs.
• This 2018 epidemiological survey in China highlights the need to clarify factors influencing hospital death in shock cases.
• Targeted strategies addressing specific shock types and comorbidities like malignant tumors are necessary to reduce mortality.
