Emergency Department Visits for Kidney Disease Patients During COVID-19

Kyung Won Kim analyzed 159,456 emergency department visits by adult patients with end-stage kidney disease in South Korea from January 2018 to May 2021. The study compares visit frequency, causes, severity, hospitalization, and mortality between pre-pandemic and pandemic periods using data from the National Emergency Department Information System.

Use Cases

• Analyzing trends in ED visit frequency and presenting causes like vascular access complications across pre-pandemic and pandemic periods.
• Modeling the odds of hospitalization and mortality using adjusted odds ratios and confidence intervals from logistic regression.
• Comparing clinical severity and patient distribution across hospital service levels before and during the COVID-19 outbreak.
• Studying associations between severe conditions and outcomes like in-hospital mortality during the pandemic.

Strengths

• 159,456 ED visit records analyzed.
• Data spans over three years from January 2018 to May 2021.
• National coverage from South Korea's NEDIS database.

Limitations

• Dataset is a 38.2 KB DOCX file, indicating limited scope and likely containing summary statistics rather than raw patient-level data.
• Specific column names and sample data are unavailable, limiting direct analytical use.
• Temporal coverage ends in May 2021, making the data stale for current pandemic analysis.
