PY - 2009 DA - 2009/09/01 TI - Improved hospital-level risk adjustment for surveillance of healthcare-associated bloodstream infections: a retrospective cohort study JO - BMC Infectious Diseases SP - 145 VL - 9 IS - 1 AB - To allow direct comparison of bloodstream infection (BSI) rates between hospitals for performance measurement, observed rates need to be risk adjusted according to the types of patients cared for by the hospital. However, attribute data on all individual patients are often unavailable and hospital-level risk adjustment needs to be done using indirect indicator variables of patient case mix, such as hospital level. We aimed to identify medical services associated with high or low BSI rates, and to evaluate the services provided by the hospital as indicators that can be used for more objective hospital-level risk adjustment.
