Heart Failure Patient Readmissions by Discharge Destination in China, 2016-2019

A retrospective cohort study of 2,008 heart failure patients admitted to a hospital in Zigong City, China, between December 2016 and June 2019. The data was analyzed to examine the association between discharge destination (home vs. healthcare facility) and readmission risk at 28 days, 3 months, and 6 months. The dataset was created by author Xia Yun and shared under a CC-BY-4.0 license.

Use Cases

• Modeling readmission risk based on discharge destination and other patient factors mentioned in the study.
• Analyzing time-to-event outcomes for heart failure patients using the reported Kaplan-Meier and Cox regression methods.
• Conducting subgroup analyses to explore the robustness of the discharge destination association across different patient populations.
• Benchmarking readmission rates for heart failure patients in a specific Chinese healthcare context.

Strengths

• Study includes 2,008 patient records, providing a substantive cohort for analysis.
• Analysis covers multiple time horizons for readmission (28 days, 3 months, 6 months).
• Uses multivariable Cox regression and Kaplan-Meier analysis, suggesting structured time-to-event data.

Limitations

• Row count for the final analytic cohort is unclear (836 enrolled vs. 2,008 admitted).
• Column-level documentation is absent; field semantics must be inferred after download.
• Data is from a single hospital in one Chinese city, which may limit generalizability.
