Clostridium difficile Infection (CDI) in California Hospitals, 2013 

This report on Clostridium difficile (C. difficile) infections (CDI) in California general acute care hospitals is the fifth by the California Department of Public Health (CDPH) and the fourth using information submitted by California hospitals to the Centers for Disease Control and Prevention (CDC) National Healthcare Safety Network (NHSN). Data were reported from January 1, 2013 through December 31, 2013. The data presented in this report are based on laboratory identification of hospital-onset (HO) CDI cases. Each case is categorized by whether illness onset occurred in a hospital or in the community. Hospital-onset (HO) cases are those for which the positive stool sample for CDI was obtained on day four or later during the hospital stay.

In this report, for general acute care hospitals (other than long-term and rehabilitation acute care hospitals), we provide the NHSN HO CDI standardized infection ratio (SIR), which adjusts for significant risk factors. Risk factors found to be significant in predicting HO CDI incidence include the type of CDI test used by the hospital, if the hospital is affiliated with a medical school, hospital bed size, and the burden of community-onset CDI in patients admitted to the hospital.  Adjusting for these factors provides for a more accurate comparison of hospitals’ infections.

Currently, there are no risk-adjusted SIRs for long-term acute care (LTAC) and rehabilitation hospitals, thus we instead report the HO CDI rates and whether a hospital uses the polymerase chain reaction test (PCR) to detect CDI.  The sensitivity of the PCR test (i.e., the ability of the test to detect C. difficile can be as much as two times greater than other laboratory methods.  Rates for LTAC and rehabilitation hospitals that use PCR have not been adjusted to account for this difference in laboratory test sensitivity.
