My EBP project involves the early mobility of ICU and its effect on hospital length of stay. When evaluating the results of an EBP project the independent and dependent variables are collected to measure success. Independent variables are those that stand alone and are not changed by other variables (National Center for Education Statistics, n.d.). In my project the independent variable is early mobility. Dependent variables are those that depend on other factors (National Center for Education Statistics, n.d.). The dependent variable in my project is the length of stay in the hospital. The independent variable is the one that is manipulated in order to influence the dependent variable (Shuttleworth & Wilson, 2008). Implementation of an early mobility protocol for ICU patients should have a positive effect on patients by decreasing the hospital length of stay. Ideally data would be collected on ICU patients before implementation of the protocol then again a month after starting the protocol. This would give baseline hospital length of stay data on current practice, no early mobility protocol, compared to hospital length of stay after early mobility is implemented.

Your rationalization of unbiased and dependent variables in your EBP mission is correct. The unbiased variable is the one that’s manipulated so as to affect the dependent variable, which is the end result that’s measured. On this case, early mobility is the unbiased variable, and hospital size of keep is the dependent variable.

It’s important to have clear definitions of those variables to measure the effectiveness of an intervention precisely. Gathering knowledge earlier than and after implementing the early mobility protocol for ICU sufferers is an acceptable method to find out the affect of the intervention on hospital size of keep.

It is usually essential to contemplate any confounding variables which will have an effect on the outcomes. For instance, the severity of sickness or comorbidities of the sufferers could affect the hospital size of keep, no matter whether or not or not they obtain early mobility. Controlling for these components will assist be certain that any variations noticed are as a result of intervention and never different variables.

Total, understanding unbiased and dependent variables is important in EBP initiatives to precisely measure the affect of an intervention and make evidence-based selections.
