An independent variable is the variable that is stable and unaffected by the other variables you are trying to measure (Kowalczyk, 2017). The independent variables that need to be collected in order to evaluate the effectiveness of a urinary catheter protocol implemented in the SICU are the number of patients admitted to the SICU and the number of patients admitted to the SICU with a urinary catheter. These numbers are used to define the population and as reference numbers to compare the dependent variable numbers to.
A dependent variable is the variable that depends on the other factors that are measured (Kowalczyk, 2017). These variables are expected to change when experimental manipulation of the independent variable or variables are performed (Kowalczyk, 2017). The dependent variables that need to be collected in order to evaluate the effectiveness of a urinary catheter protocol implemented in the SICU are the number of CAUTIs, the number of straight caths performed, and the number of urinary catheters replaced. Evaluation of these numbers when compared pre and post-implementation will demonstrate protocol effectiveness.
