Field definitions supplied by the publishing agency in CKAN.

Column	Type	Label	Description
Year	text	—	Calendar year, 2025
State	text	—	California
HAI	text	—	Healthcare-associated infection (HAI): Central Line-Associated Bloodstream Infection (CLABSI)
Facility_ID	text	—	Facility ID. The primary key used to track facility information for all facilities stored in the Electronic Licensing Management System (ELMS) for California Department of Public Health (CDPH) Center of Healthcare Quality, Licensing and Certification Program.
Facility_Name	text	—	Facility name for California general acute care hospitals reporting to the Centers for Disease Control and Prevention (CDC) National Healthcare Safety Network (NHSN) in calendar year 2025.
County	text	—	The name of the California county where the facility is located, derived from COUNTY_CODE in the FACILITY table in ELMS, obtained from the facility's license application form.
Hospital_Category_RiskAdjustment	text	—	California general acute care hospitals are categorized into four major categories consistent with the categories NHSN uses for risk adjustment: 1) Acute Care Hospital, 2) Long-Term Acute Care Hospital, 3) Critical Access Hospital, and 4) Rehabilitation Hospital or Unit.
Facility_Type	text	—	Specific types of California hospitals are Major Teaching; Pediatric; Community, >250 Beds; Community, 125-250 Beds; Community, <125 Beds; Long-Term Acute Care (LTAC); Critical Access; Free-Standing Rehabilitation; and Rehabilitation Unit. A major teaching hospital is a hospital that has a teaching program for medical students and a post-graduate medical training program. A pediatric hospital is a hospital with inpatients predominantly age 18 years or younger. A community hospital is a CDPH designation for hospitals not classified as major teaching, long-term acute care (LTAC), critical access, pediatric, or rehabilitation. Community hospitals are further categorized by number of active beds as reported by the hospital in the NHSN Annual Survey. A LTAC hospital is defined by the Centers for Medicare & Medicaid Services (CMS) as a licensed general acute care hospital providing care for patients with medically complex conditions requiring an average length of stay greater than 25 days. A critical access hospital is designated by CMS as a hospital with 25 or fewer acute care inpatient beds, located more than 35 miles from another hospital (with some exceptions), with an average length of stay of four days or less. A rehabilitation hospital is an acute care facility exclusively providing evaluation and restoration of function for patients who have lost function due to acute or chronic pain, musculoskeletal problems, stroke, or catastrophic events resulting in complete or partial paralysis. A rehabilitation unit is an inpatient ward within a general acute care hospital providing evaluation and restoration of function for patients who have lost function due to acute or chronic pain, musculoskeletal problems, stroke, or catastrophic events resulting in complete or partial paralysis. A rehabilitation unit typically has its own unique CMS certification number (CCN) and reports separately from the rest of the hospital.
Infections_Reported	text	—	Number of reported CLABSIs. A rehabilitation unit with its own CCN number reports separately from the rest of the hospital. The "NHSN Patient Safety Component Manual" document contains the specific criteria for CLABSI surveillance and reporting and provides examples of how to apply the CLABSI definition. See the NHSN website: http://www.cdc.gov/nhsn.
Infections_Predicted	text	—	The predicted number of CLABSI as determined by the 2022 national baseline data, adjusting for significant risk factors outlined in the NHSN Guide to the SIR.
Central_line_Days	text	—	The number of patients with central lines counted at the same time each day. At the end of the month, the daily counts are summed and entered into NHSN. Central line data from electronic databases may be used as long as the counts are not substantially different (+/- 5%) from manually-collected counts, validated for a minimum of 3 months. See the NHSN website: http://www.cdc.gov/nhsn.
SIR	text	—	The standardized infection ratio (SIR) is a summary measure used to track HAIs over time. The SIR compares the number of reported CLABSIs to the number of predicted (expected) number of CLABSIs, based on national baseline data. The SIR also adjusts for several factors that may impact the risk of acquiring a CLABSI. Hospitals with NHSN-predicted number of CLABSI <1 had no SIRs calculated by NHSN. An SIR was calculated by CDPH if the predicted number of infections was <1 and >=0.2. The SIR and its comparison are not as accurate as SIRs based on a larger number of predicted infections.
SIR_CI_95_Lower_Limit	text	—	Lower limit of the SIR 95% confidence interval calculated using exact Poisson distribution. The confidence interval quantifies the precision of the calculated SIR that is associated with random variation. NOTE: If the 95% CI for the SIR includes 1, the number of reported infections is not statistically different from that predicted.
SIR_CI_95_Upper_Limit	text	—	Upper limit of the SIR 95% confidence interval calculated using exact Poisson distribution. The confidence interval quantifies the precision of the calculated SIR that is associated with random variation. NOTE: If the 95% CI for the SIR includes 1, the number of reported infections is not statistically different from that predicted.
Comparison	text	—	The calculated SIR 95% confidence interval indicates if the observed number of infections was significantly different from the predicted number of infections. Based on the SIR 95% confidence interval, we labeled each SIR as indicating: 'Better' (fewer observed infections than predicted), 'Same' (no significant difference in the number of observed and predicted infections), 'Worse' (more observed infections than predicted).' This field is blank if the predicted number of infections was <0.2.
On_Track	text	—	Yes indicates hospital is on track to meet the 2028 national HAI reduction goal in calendar year of 2025. In 2025, hospitals should have achieved incremental progress goal of 16% reduction (SIR<=0.84) towards the 2028 40% reduction goal.
Months	text	—	California hospitals are required to report data throughout each calendar year on a quarterly basis. NHSN data are downloaded in monthly units. This field indicates the number of months for which a hospital reported "complete" data, defined as a numerator (CLABSI cases or zero CLABSI) and a denominator (central line days).
Notes	text	—	A hospital labeled "Incomplete Reporter" is a hospital reporting in-plan CLABSI data for fewer months than it was operational. See the Patient Safety Monthly Reporting Plan and Annual Surveys document (https://www.cdc.gov/nhsn/pdfs/pscmanual/3psc_monthlyreportingplancurrent.pdf) for NHSN's monthly reporting plan definitions. ¥ SIR was calculated by CDPH if the predicted number of infections was <1 and >=0.2. The SIR and its comparison are not as precise as SIRs based on a larger number of predicted infections.
