Variables are important to understand because they are the basic units of the information studied and interpreted in research studies. Researchers carefully analyze and interpret the value of each variable to make sense of how things relate to each other in a descriptive study or what has happened in an experiment (Dept of health and Human Services, 2021). An independent variable is the variable you manipulate or vary, in an experimental study, to explore its effects. It is called “independent” because it is not influenced by any other variables in the study. A dependent variable is the variable that changes because of the independent variable manipulation. It is the outcome you are interested in measuring, and it “depends” on your independent variable (Andrade, 2021). Simply put, independent and dependent variables of a research study have a cause-and-effect relationship; where the independent variable is the cause, and the dependent variable are the effect.

My Capstone change project is a urine culture stewardship initiative implemented at a rehabilitation hospital. My project is evaluated based on outcomes including a reduction in CAUTI rates, a decrease in the number of urine cultures ordered and a reduction of the number of patients inappropriately treated. Patients with indwelling urinary catheters and CAUTI rates have been identified as independent variable related to my change project. These variables are manipulated by the dependent variables which include the urine culture stewardship education and urine culture collection practices, both which directly influence the patients being treated as well as CAUTI rates.

! Understanding the dependent and independent variables are extremely important with respect to our capstone change projects. Being able to understand how the interventions will influence our research. And the results that come about from the interventions and change implemented. The capstone project that I am doing is on fall prevention, the use of bed alarms and the implementation of hourly rounding. As fall continues to be a concern, having a intervention in place to try and prevent these falls from occurring is extremely important. Falls lead our patients to be at risk for injuries and prolonged hospital stays. As most of our populations in the healthcare field are those of the elderly, falls in this population can lead to many devastating outcomes that can include death. The incidence of falls also leads to a large cost to the healthcare system as well. There are many interventions that be put into place such keeping the bedside table within reach, call light within reach, patients have been toilet, and pain medications given. Of course, falls can still occur but placing interventions to try and prevent these falls from occurring is an important task in our daily activities with our patients. There are different ways to measure how the interventions we put into practice are working. Such as seeing a reduction in falls and see an improvement with patient satisfaction with their care, we can see that the intervention is working. Seeing a reduction in call lights as well can be beneficial.

Urine Culture retention is a good topic especially in the rehabilitation hospital. Quality Reporting Program are used

by the center for disease control as away of reporting each hospitals data to the center For Medicare and Medicaid services. Patients receiving rehab may require catheter use because of conditions that caused them to require rehabilitation. Monthly coverage schedules are utilized for CAUTI surveillance in localities where exposure is found. CAUTI investigation must use with to report to these agencies. All records set must be submitted to National Healthcare Safety Network even if no cases are observed.  Statically data is very important to collect.

Indeed, variables can be said to be the fundamental units of knowledge or specific information, especially when reviewing, analyzing, and translating the latest scientific research and evidence. With the availability of both independent and dependent variables, it is pretty important for the researchers to analyze their values and also see their relationship. You stated your definitions with clarity, and one could not agree less. In a concise way, I could add the definition of the independent variable as what the scientist changes or what changes (manipulated variable) on its own in research. In other words, the independent variable must be changed by the scientist, or it will change on its own; nothing else in the experiment affects or alters it (Sarikas, 2018). On the other hand, the dependent variable can also be briefly defined as; What is being studied or measured in an experiment. It is sometimes known as the responding variable, I.e., what shifts when the independent variable is changed or changes.

Your project serves as a great explanation for distinguishing dependent variables from independent variables. Notably, your project has a number of variables which makes it even more interesting. Thank you for also first giving a good and understandable brief of the project. I’m, however, a bit confused with the classifications. I would initially think that since urine culture collection practices and urine culture stewardship education can both be manipulated; they would best be taken as the independent variables subject to clarification. Thank you.


Sarikas, C. (2018). Independent and Dependent Variables: Which Is Which?

Two factors must be examined in research or EBP projects (independent and dependent variables). The dependent variable is what occurs as a result of the independent variable, while the independent variable is what we expect to influence the dependent variable (National Library of Medicine, n.d.). Independent variables are conditions that can be altered in an experiment or project, whereas dependent variables measure reaction or consequences. On one hand, in a scientific experiment, the independent variable is the variable that is manipulated or altered to see how it affects the dependent variable (Polit & Beck, 2015). The dependent variable, on the other hand, is the variable being tested and measured in the study or experiment. As a result, the dependent variable is the one that is affected by the independent variable’s results. The independent variable is affected or changed by the experiment or study, which in turn impacts or changes the dependent variable (Polit & Beck, 2015).

Based on the evaluation of my EBP project, the independent variables include the actual data (expressed in percentages) of mothers who were not able verbalize the benefits of breastfeeding during the audit. The dependent variable will be the percentage increase of patients who were able to verbalize 4 benefits of breastfeeding in an audit after receiving education from the clinic staff. Essentially, the EBP project seeks to identify if the implementation of a performance improvement initiative focused on increased patient education, therefore improving patient knowledge and increasing breastfeeding audit results.
