California spends $3.1 billion each year on hospital-acquired infections 1

This indicator includes incidence of measurable hospital-acquired conditions (per 1,000 discharges).  This data is comprised of a composite patient safety indicator, which includes an average of the observed-to-expected ratios of several other selected indicators of quality.  The available data is limited and there remains opportunity for further development to establish a more definitive measure. At present, this indicator serves as a useful starting point for examining hospital quality. With sustained and system-wide quality improvement efforts in hospitals, safety and quality of care for patients can be enhanced and billions of dollars saved.

Indicator Progress

In 2011 (baseline year), there were 0.761 hospital-acquired conditions per 1,000 discharges. The most recent rate available is 0.870 (2019). We hope to reach a target of 0.500 or lower by 2022.

Healthcare Associated Infections Program (HAI)

Healthcare Associated Infections Program (HAI) is part of the Center for Health Care Quality of the California Department of Public Health. The Program was created by mandate to oversee the prevention, surveillance and reporting of healthcare-associated infections in California’s general acute care hospitals.

HAIs are the most common complication of hospital care. The vision of the HAI Program is to eliminate HAIs for all Californians. The HAI Program produces annual public reports of hospital HAI data to inform choices of healthcare consumers and prompt providers to take actions to prevent infections; actively engages in HAI prevention by performing site visits to hospitals with high infection rates, convening prevention collaboratives, and provides infection prevention education; and consultation and assistance to local public health for infection outbreaks that occur in healthcare facilities.

Healthcare Associated Infections (HAIs) result in an estimated $30 billion in excess healthcare costs nationally each year.2

It is estimated that each year there are 722,000 infections, 75,000 deaths, and 1 in 25 hospital patients at any given time has an infection contracted during the course of their hospital care.2

Indicator: Incidence of measureable hospital-acquired conditions (per 1,000 discharges)

Description: This data contains composite patient safety indicator (PSI), the weighted average of the reliability-adjusted observed-to-expected ratios for selected indicators. The composite PSI includes the following component indicators: pressure ulcer, iatrogenic pneumothorax, central venous catheter related, blood stream, postoperative hip fracture, perioperative pulmonary embolism, deep vein thrombosis, postoperative sepsis, postoperative wound dehiscence, accidental puncture, laceration. The indicator was calculated using the California Office of Statewide Health Planning & Development (OSHPD) Patient Discharge Data run through the Agency for Healthcare Research and Quality’s Patient Safety Indicator Software, Version 4.4.

Data Limitations: California hospital medical record data for the reported medical conditions and procedures have not been validated through medical record reabstraction to demonstrate that patient severity-of-illness and complications are accurately and reliably coded across all hospitals. OSHPD views these indicators as potentially useful starting points for examining hospital quality but does not regard them as definitive measures of quality. Data for 2015 are reported for nine months only due to a coding change from ICD-9 to ICD-10. Comparisons across years should be made with caution since 2011-2014 results are based on 12 months of data, while the 2015 rate is based on 9 months of data.
