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.
