ICU Admissions and Outcomes for Elderly Patients in China, 2014-2021

A dataset of 31,535 ICU patient records from a tertiary referral hospital in China, spanning January 2014 to December 2021. It categorizes patients into three age groups and tracks trends in admission rates, mortality, and resource use. The data was collected and analyzed by Xiaohui Zhu.

Use Cases

• Analyzing trends in ICU admission rates based on age group and year mentioned in the description
• Comparing hospital mortality rates and risk-adjusted mortality reductions across different patient cohorts
• Studying changes in clinical resource utilization, such as invasive ventilation and blood transfusions, over time

Strengths

• Contains 31,535 patient records, providing a substantial sample size for analysis
• Covers an 8-year time period (2014-2021), enabling longitudinal trend analysis
• Includes specific, reported metrics such as hospital mortality rates (14.1% for elderly) and relative admission rate decreases (31.8%)

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
• Data is from a single tertiary hospital in China, which may limit generalizability
