Description
California Health and Safety Code section 1288.55(a)(1) requires general acute care hospitals to report all cases of Clostridioides difficile infections (CDI) identified in their facilities to the California Department of Public Health (CDPH). CDI data are submitted by hospitals to the Centers for Disease Control and Prevention (CDC) National Healthcare Safety Network (NHSN).
CDPH downloads California hospital CDI data from NHSN and analyzes the data to describe prevention progress in an annual public report of healthcare-associated infections CDPH publishes annual CDI data reported by each California hospital in the datasets below.
The following datasets include the number of CDI reported by each California hospital in the specified reporting year. Beginning in 2016 for each California hospital, the annual CDI dataset includes the number of CDI that were predicted to occur in each hospital based on its specific facility-level characteristics. The observed (reported) number of CDI are then compared to the predicted number of CDI in a ratio called the Standardized Infection Ratio or SIR. The SIR is a metric that summarizes an individual hospital’s CDI prevention progress compared with the national baseline and California state-specific prevention goals.
Detailed information about the variables included in each dataset are described in the accompanying data dictionaries for the year of interest.
For more information about the SIR and NHSN’s statistical models that are used to calculate the predicted number of CDI for each hospital, please review “NHSN’s Guide to the SIR”: https://www.cdc.gov/nhsn/ps-analysis-resources/index.html
