Inpatient Mortality Rate for Hip Replacement The inpatient mortality rate for elective primary and revision hip replacement procedures at Highland Hospital was 0.15% in 2011, which is similar to the rate of 0.15% for hip replacement in University HealthSystem Consortium hospitals like Highland. The mortality rate (measured as a percentage) provides general information about the quality of care delivery, and can be an important quality indicator. However, some hospitals care for patients with a greater severity of illness and therefore may have a higher mortality rate. Hip replacement, an elective surgery, has a relatively low mortality rate. The known predictors of inpatient mortality include age, and the presence of any significant coexisting conditions. University HealthSystem Consortium (UHC), is an alliance of 107 academic medical centers and 220 of their affiliated hospitals, representing approximately 90% of the nation’s non-profit academic medical centers.
