CalHospitalCompare shows California hospital quality ratings for cancer surgery, heart care, hip and knee, gallbladder infections, surgery volume, pneumonia, COPD, stroke, preventing surgical infections & complications, maternity care including c-sections and VBAC, emergency department and patient opinion ratings, readmissions; some mortality/survival rates. Dates of data are hard to find (click on the red question marks when at the hospital report). When reported, most contain 2020-2021 data. Number of cancer cases is labeled as both 2014 and 2020, which is confusing. Compare hospitals side by side to find Superior Hospitals. Hospitals may be the best in one area but not in another. When viewing hospital report, click on View All, or you’ll miss most of the information. Cal Hospital Compare is supported by IBM Watson Health.
