The dataset contains risk-adjusted mortality rates, and number of deaths and cases for 6 medical conditions treated (Acute Stroke, Acute Myocardial Infarction, Heart Failure, Gastrointestinal Hemorrhage, Hip Fracture and Pneumonia) and 6 procedures performed (Abdominal Aortic Aneurysm Repair, Carotid Endarterectomy, Craniotomy, Esophageal Resection, Pancreatic Resection, Percutaneous Coronary Intervention) in California hospitals. The 2014 and 2015 IMIs were generated using AHRQ Version 5.0, while the 2012 and 2013 IMIs were generated using AHRQ Version 4.5. The differences in the statistical method employed and inclusion and exclusion criteria using different versions can lead to different results. Users should not compare trends of mortality rates over time. However, many hospitals showed consistent performance over years; “better” performing hospitals may perform better and “worse” performing hospitals may perform worse consistently across years. This dataset does not include conditions treated or procedures performed in outpatient settings.

The dataset contains risk-adjusted mortality rates, quality ratings, and number of deaths and cases for 6 medical conditions treated (Acute Stroke, Acute Myocardial Infarction, Heart Failure, Gastrointestinal Hemorrhage, Hip Fracture and Pneumonia) and 5 procedures performed (Abdominal Aortic Aneurysm Repair, Unruptured/Open, Abdominal Aortic Aneurysm Repair, Unruptured/Endovascular, Carotid Endarterectomy, Pancreatic Resection, Percutaneous Coronary Intervention) in California hospitals. The 2022 IMIs were generated using AHRQ Version 2023, while previous years' IMIs were generated with older versions of AHRQ software (2021 IMIs by Version 2022, 2020 IMIs by Version 2021, 2019 IMIs by Version 2020, 2016-2018 IMIs by Version 2019, 2014 and 2015 IMIs by Version 5.0, and 2012 and 2013 IMIs by Version 4.5).

The dataset provides performance ratings for coronary artery bypass graft (CABG) surgery, inpatient mortality indicators (IMIs), and elective percutaneous coronary intervention (PCI). The outcome measures include: operative mortality for isolated CABG; inpatient mortality for acute stroke, acute myocardial infarction, heart failure, gastrointestinal hemorrhage, hip fracture, pneumonia, abdominal aortic aneurysm repair, carotid endarterectomy, esophageal resection, pancreatic resection, percutaneous coronary intervention; three outcome measures for elective PCI without on-site cardiac surgery: mortality, post-PCI stroke, and post-PCI emergency coronary artery bypass graft surgery. It includes risk-adjusted rates, number of adverse events and cases.

The dataset provides performance ratings for two outcome measures for transcatheter aortic valve replacement (TAVR) procedures: in-hospital/30-day mortality and in-hospital/30-day stroke. It includes the number of cases, adverse events, risk-adjusted rates, and performance ratings for hospitals compared to the overall statewide rates. This dataset also contains the location of hospitals that perform TAVR procedures in California.

This dataset contains the location of hospitals that performed Coronary Artery Bypass Graft (CABG) surgery in California from 2011 to 2022. It also provides performance ratings for the following risk-adjusted outcome measures related to the CABG surgery: operative mortality for isolated CABG and CABG plus valve, post-operative stroke, and 30-day all cause readmission. The dataset also includes the number of cases and adverse events for each CABG outcome measure. The methodology, including risk models that generated the rates and performance ratings differed among years. Users should exercise caution when comparing trends of rates over time (see metadata for more information).

(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.

This dataset contains the statewide composite patient safety and Adverse Events indicator (PSI) rate used to determine the “Incidence of measurable hospital-acquired conditions” rate for the Let’s Get Healthy California Initiative. PSI rates may not be comparable across years as significant changes were made to composition, definition, and calculation of PSI over time. The current composite PSI includes the following component indicators: pressure ulcer, iatrogenic pneumothorax, in-hospital fall-associated fracture, postoperative hemorrhage or hematoma, postoperative acute kidney injury requiring dialysis, postoperative respiratory failure, perioperative pulmonary embolism or deep vein thrombosis, postoperative sepsis, postoperative wound dehiscence, abdominopelvic accidental puncture or laceration.

The dataset contains in-hospital postoperative sepsis cases, elective surgical discharges, risk-adjusted sepsis rates, and performance ratings for California hospitals. This dataset does not include sepsis acquired in outpatient settings.

These datasets show surgical site infections (SSIs) reported by California hospitals to the California Department of Public Health (CDPH), Healthcare-Associated Infections (HAI) Program, via the Centers for Disease Control and Prevention National Healthcare Safety Network (NHSN), in accordance with Health and Safety Code (HSC) section 1288.55. California hospitals track and report deep incisional and organ/space SSIs for adults and pediatric (<18 years of age) patients for 28 types of operative procedures: abdominal aortic aneurysm repair; abdominal hysterectomy; appendix surgery; bile duct, liver or pancreatic surgery, cardiac surgery; Cesarean section; colon surgery; coronary artery bypass graft with both chest and donor site incisions; coronary artery bypass graft with chest incision only*; exploratory abdominal surgery (laparotomy); gallbladder surgery; gastric surgery; heart transplant; hip prosthesis; kidney surgery; kidney transplant; knee prosthesis; laminectomy; liver transplant; open reduction of fracture; ovarian surgery; pacemaker surgery; rectal surgery; small bowel surgery; spinal fusion; spleen surgery; thoracic surgery; vaginal hysterectomy The SSI data tables include information on the statewide and hospital-specific SSI incidence by operative procedure types, displaying procedure counts, number of infections observed (reported) and predicted. NHSN calculates the number of predicted infections using procedure-specific risk adjustment logistic regression models based on 2015 national baseline data and that accounts for particular patient-level factors and hospital characteristics found to be significant predictors of SSI incidence. Detailed information about the variables included in each dataset are described in the accompanying data dictionaries for the year of interest.
