Objective:

To conduct a meta-analysis to quantify the incidence of delirium in hospitalized heart failure patients.

Approach:

Key Findings:

• Pooled incidence of delirium in hospitalized HF patients was 18.5% (95% CI: 13.1%–24.6%).
• Subgroup analysis indicated factors influencing delirium incidence include publication year, country, sex, age, screening tools, and comorbidities.
• No publication bias was detected.

Interpretation:

Incident delirium is common in hospitalized HF patients, affecting nearly one in five.

Limitations:

• Substantial heterogeneity across estimates.
• Limited to studies published in English or Chinese.

Conclusion:

Findings highlight the need for systematic screening and routine assessment of delirium during hospitalization.
