California State Water Resources Control Board

This dataset describes the biological condition of nearly 600 sites in Southern California streams based on the condition of benthic invertebrate communities, a key indicator of stream health. The California Stream Condition Index (CSCI), a measure of biological condition based on benthic macroinvertebrates, was calculated at each of these sites and provides a consistent way to characterize biological condition across multiple river-types. For more information on the CSCI, refer to the <a href="http://www.waterboards.ca.gov/water_issues/programs/swamp/bioassessment/docs/csci_factsheet.pdf">CSCI Fact Sheet</a>. The underlying bioassessment data is from sampling programs supported by the California State Water Resources Control Board's Surface Water Monitoring Program (SWAMP).

Biological Endpoints

Data dictionary for the Biological Endpoints csv file, describing the data contained in each field.

Biological Endpoints - Data Dictionary

This dataset describes the hydrologic metrics used to characterize the degree of hydrologic alteration at each of the sites included in this study. The degree of hydrologic alteration at each site is assessed by comparing estimates of present-day and historical flows using a set of regionally calibrated hydrologic models. The hydrologic metrics in this dataset can be compared to the biological condition at corresponding sites (described in the Biological Endpoints dataset) to estimate the probability of good biological conditions along gradients of increasing hydrologic alteration.

Hydrologic Metrics

Hydrologic Metrics - Data Dictionary

This dataset describes the sites assessed as part of this study to determine their biological condition and degree of hydrologic alteration. The information includes the each site’s geographic location, stream classification at that location, scores indicating the hydrologic and biological condition of the site, and the management priority assigned to the site based on its hydrologic and biological condition.

Hospitals who did not report surgical procedures, 2018

This table shows the incidence of surgical site infections (SSI) reported by California general acute care hospitals for 28 operative procedures performed on adult patients (procedures listed in the Data Dictionary). SSI incidence is presented using the Centers for Disease Control and Prevention National Healthcare Safety Network (NHSN) risk adjusted standardized infection ratios (SIR) for SSI. 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 2016 NHSN data, which represents a reference population (baseline) for each procedure type. SIRs are based on procedure date, not the date of the infection event. All procedure and infection data for surgical procedures performed between January 1, 2017, and December 31, 2017, were downloaded from NHSN in 12, 2018. The SIR reported in this table include only complex SSI (deep incisional and organ/space) identified during hospital Admission or Readmission to the same hospital. NHSN calculates an SIR only if the number of observed is at least 1 to meet a minimum precision criterion. CDPH calculated an SIR if the predicted number of infections was less than 1 and greater than or equal to 0.2; these SIRs and comparisons are not as precise as SIRs based on a larger number of predicted infections, but provide more hospitals with a published interpretation of their data. For a detailed explanation, please see the Technical Notes. Each hospital's reported procedure and infection counts are displayed along with an SIR, the 95 percent confidence interval for the SIR, and the statistical comparison as follows:

• Better - lower or fewer infections than predicted,

• Same - no difference in number of observed and predicted infections, or

• Worse - higher or more infections than predicted.

SSI in Adult Patients, 2017

For a detailed explanation, please see the Technical Notes. Each hospital's reported procedure and infection counts are displayed.
