Hospitalization Counts and Rates of Selected Adverse Hospital Events by California County

Published by Department of Health Care Access and Information | State of California | Metadata Last Checked: November 28, 2025 | Last Modified: 2025-11-07T01:46:00.262072
(See Note below regarding 2015 data). The dataset contains hospitalization counts and rates (age 18+), statewide and by county, for 7 potentially-preventable adverse events that occur during a hospital stay. They provide a perspective on complications and iatrogenic events and help assess total incidence within a region. The measures, based upon the Agency for Healthcare Research and Quality’s (AHRQ’s) Patient Safety Indicators (PSIs), include: retained surgical item or unretrieved device fragment, iatrogenic pneumothorax, central venous catheter-related blood stream infection, postoperative wound dehiscence, accidental puncture or laceration, transfusion reaction, and perioperative hemorrhage or hematoma. Note: HCAI is only releasing the first 3 quarters of 2015 data due to a change in the reporting of diagnoses/procedures from ICD-9-CM to ICD-10-CM/PCS effective October 1, 2015, and the inability of the AHRQ software to handle both code sets concurrently.
