Summary

Description

This table shows the Centers for Disease Control and Prevention National Healthcare Safety Network (NHSN) risk adjusted standardized infection ratios (SIR) for surgical site infections (SSIs) reported by hospitals for 24 operative procedures that are listed in the Data Dictionary. The SIR is calculated by dividing the number of observed infections by the number of predicted infections. The number of predicted infections is calculated using SSI probabilities estimated from multivariate logistic regression models constructed from NHSN data during a baseline time period 2006 through 2008, which represents a reference population’s SSI experience. To enforce a minimum precision criterion, an SIR is calculated only if the number of observed infections is at least one. SIRs are based on the date of procedure, not the date of the SSI event. All procedure and infection data entered before May 1, 2014 for surgical procedures performed between January 1 and December 31, 2013 were downloaded from NHSN for this data release. The SIR used for this table is a risk adjusted SIR that considers only complex SSI identified during hospital admission or readmission to the same hospital following inpatient surgeries. The procedure counts and infection counts submitted by each hospital are displayed along with an SIR, the 95 percent confidence interval for the SIR, and the statistical comparison as follows: * No difference - no difference in number of observed and predicted infections • High - more infections than predicted, or • Low - fewer infections than predicted To link the CDPH facility IDs with those from other Departments, like OSHPD, please reference the "Licensed Facility Cross-Walk" Open Data table at https://chhs.data.ca.gov/Facilities-and-Services/Licensed-Facility-Cross...
