Why are central line-associated bloodstream (CLAB) infections and surgical site infections (SSIs) reported as (half ), (empty circle ), or (full ), while head of bed (HOB) elevation data are reported numerically?

CLAB and SSI data are related to actual infections and are analyzed using risk stratification and other statistical methods so the public can make fair comparisons among facilities. HOB elevation data are not related to actual infections – HOB is a process measure that has been proven to prevent ventilator-associated pneumonia (VAP). The goal is to have the ventilated patient’s HOB elevated 100 percent of the time (when appropriate). Therefore, it was decided to report the percentage of time the HOB was elevated, as an indicator of the hospital’s performance.
