California Respiratory Virus Hospitalization and Death Metrics (Archived)

Archived hospitalization, ICU admission, and death data for COVID-19 and influenza in California from summer 2020 to April 2024. Data sources include the California Hospital Association Survey and CDC's National Healthcare Safety Network. The dataset includes metrics on testing, deaths, and hospitalizations.

Use Cases

• Analyze COVID-19 and influenza hospitalization trends over time using data from the California Hospital Association Survey and CDC NHSN.
• Compare state-level influenza testing data from clinical sentinel laboratories against COVID-19 electronic laboratory reporting results.
• Investigate the impact of data source changes on death metrics, comparing the COVID-19 case registry to the California Comprehensive Death File.

Strengths

• Includes data from multiple authoritative sources: California Hospital Association Survey and CDC's National Healthcare Safety Network.
• Covers a multi-year time range from summer 2020 through April 2024 for longitudinal analysis.
• Contains multiple data types including hospitalization, ICU admission, death, and testing metrics for two major viruses.

Limitations

• Dataset is archived and not updated beyond April 30, 2024, limiting analysis of recent trends.
• Influenza testing data is aggregated weekly from sentinel labs and does not represent all testing in California.
• COVID-19 testing data has reporting lags, including a 7-day lag for Los Angeles County.
