                             Effect of a Nurse-Driven Mobility Protocol

The  title of the study that I have chosen is “the effect of a nurse-driven  mobility protocol.” The population that this study focuses on is that of  older adults. The participants who took part in the study were only 50.  The purpose of the study was to find out if patients had a better  outcome of functional mobility and a decline in the length of stay after  discharge in case a nurse-driven mobility model was employed. The  nurse-driven mobility protocol that was used in the study was the  Geriatric Friendly Environmental through Nursing Evaluation and Specific  Interventions for Successful Healing. Thus nurse-driven agility was  used before the study was conducted and this gave the nurses an  opportunity to train before the study. This protocol allows the nurses  to walk patients two to three times a day for meals or to the washrooms  (Padula, Hughes, &Baumhover, 2009). 

Potential Concerns

Validity  means the degree of credibility and accuracy of information provided  during a study. Internal validity is the liberated variable being the  reason for the results as opposed to several other factors. In this  study, the internal validity is at risk from the reality that most of  the research participants in the treatment group are at a lesser risk  for falls than those from the control group (Metheny, Davis-Jackson,  & Stewart, 2010). This can have an effect on the validity of  information during the research study. This is because if the treatment  group were at a lower risk for falls, the group would be more  self-sufficient before the study which can affect the outcomes of the  research. 

 Another  concern could also be seen where the staff may seem reluctant to walk  their patients for long distances in case the patient is at risk for  falls. Another problem of validity that can be encountered is the fact  that there is no distinct definition of the exact number of times that a  patient should be walked through and the distance to be covered by the  control group. Lack of data showing the exact number of patients who  were in the control and the treatment groups could also harm the  internal validity. Another concern that may affect the validity of  information may arise where patients from a nursing home may not  participate actively as compared to those new from home. 

 Recommendations to Reinforce Internal Validity

To  reinforce the internal validity in this case, the management of nursing  care should implement clear and concise principles to guide the control  group. The assessment of how often patients are ambulated and put on a  chair for feeding should be done before the study to reinforce the  internal validity of the data. In this research, the patients should  have come from a similar environment before the admission. Using the  data for all patients in the control group could also make the data  clear thus strengthening the internal validity. They should also have  similar statuses to enhance internal validity. Before being admitted, it  is also essential for all patients to use or not use an assistive  device for uniformity purposes. Ensuring similarity between these groups  would have prevented issues of internal validity (Yuan et al. 2009).

Effects my Changes Could Have Regarding the Three Types of Validity

The  changes regarding the three types of validity will lead to  strengthening internal validity. By ensuring that all the participants  of this study come from one environment and using the same assistive  device, this will improve the validity of data during the study. Having  clear guidelines for the control group will enhance validity by  providing the best evidence.

  Dangers of Failing to Be Considering the Validity of the Research Study.

During  any research study, backing up your data through evidence-based  practices improves the decision-making process and enhances validity.  Failing to consider validity leads to weak and unreliable results which  may harm the study subjects. Therefore, it is imperative to ensure that  validity is maintained as this would lead to certain outcomes.
