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. For more information about NHSN’s statistical models, please review the “NHSN Guide to the SIR” at https://www.cdc.gov/nhsn/ps-analysis-resources/index.html To link the CDPH facility IDs with those from other Departments, like HCAI, please refer to the "Licensed Facility Cross-Walk" Open Data table at https://data.chhs.ca.gov/dataset/licensed-facility-crosswalk For more information about HAIs in California hospitals, please visit: https://www.cdph.ca.gov/Programs/CHCQ/HAI/Pages/AnnualHAIReports.aspx

Oregon hospitals report surgical site infections involving deep incisional layers (fascial and muscle) and organ/space areas following coronary artery bypass graft (CBGB), colon (COLO), abdominal hysterectomy (HYST), hip prosthesis (HPRO), knee prosthesis (KPRO), and laminectomy (LAM) procedures as part of Oregon’s mandatory healthcare-associated infections reporting program. For information regarding standardized infection ratio baselines, please see https://www.cdc.gov/nhsn/2015rebaseline/index.html

This dataset contains the number (volume) of 6 selected inpatient procedures (Esophageal Resection, Pancreatic Resection, Abdominal Aortic Aneurysm Repairs (AAA Repairs), Carotid Endarterectomy, Coronary Artery Bypass Graft Surgery, Percutaneous Coronary Intervention) performed in California hospitals. Data are reported for January – September 2015 due to coding changes from ICD-9-CM to ICD-10-CM/PCS for procedures, which began 10/1/2015. Comparisons across years should be made with caution since other years’ results are based on 12 months of data, while 2015 analysis is based on 9 months of data. The data starting 2015 may differ from previous years due to the coding change. This dataset does not include 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 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.
