| Abstract: | Background 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. |
