NR439 Evidence Based Practice


Rogers’ diffusion-of-innovation theory is a great theoretical framework to help with an EBP project.

Students might also consider using change models such the Duck’s behavior change model or transtheoretical model.

EBP models, such the Iowa model and Stetler’s model, can also be used to guide your evidence-based interventions in clinical practice.2.

Choose one of the following models and follow the steps, phases or stages that are identified in it.

Answer to Question: NR439 Evidence Based Practice

Model chosen: The Iowa Model of Evidence-Based Practice.

Harris Health System has been selected as the Chosen Organisation

Topic selected: School-Based Intervention in Asthma Prevention

Evidence-based Practice helps improve the quality of patient care as well as reduce rising healthcare costs.

Iowa Model is an evidence-based model for research that assists nurses and other healthcare professionals with translating research findings into practice and improving overall health outcomes (Brown and Associates, 2014).

The first step in the model is to identify a problem which can be solved by EBP.

The patient’s problem, or risk management data, is used to select the problem.

Based on the identification and severity of the clinical conditions, asthmatic issues that are associated to schoolchildren are chosen for the EBP.

The next step is to determine the extent of the problem based on the frequency.

The most expensive problems are given priority.

Anti-inflammatory medications used to treat asthma are too expensive for the poor and minority (Blaakman Cohen Fagnano & Halterman, 2014).

Once you have determined the priority, the next step will be to evaluate the EBP change and then implement it.

The needs of the problem will determine the composition of each member of the team.

It must include stakeholders from outside the hospital or nursing unit.

The study included both registered nurses and schoolteachers from outside the healthcare profession.

After the team has been formed, the next step will be to collect relevant research papers on the desired topic of practice changes.

This is an important step and should not be missed. It involves framing a great question using the PICOT technique.

This will allow you to do a literature search using the PICOT results.

The PICOT question for this case study is: Can effective school-based interventions reduce asthma cases in children with asthma who present to the healthcare facility more frequently than current practices?

After gathering the relevant literatures, critical analysis of each article is done to determine the relevancy and effectiveness of the intervention.

Each article with relevant keywords may not produce the desired result or have the scientific merit required.

The inclusion and exclusion criteria are used to select articles.

Criteria for Exclusion

Criteria of Inclusion


Asthma intervention


Conducted in elementary and primary school

Conducted in a location other than school

Asthma-targeted school children, asthma parents, school nurses, teachers, and a mixture of all of these groups

Targeted at different age groups

Focus groups of 50 students or more are used in studies

These articles deal with asthma drug research

Articles concerning asthma diagnosis

Articles that examine the cost-benefit of asthma

Source: Created by author

After critical review of the articles, the nursing professionals in the team must gather together.

They must discuss the findings and then reach a consensus on whether the study’s relevant articles contain significant information that matches the criteria.

If they meet the criteria, the pilot practice must begin.

But, if there is no adequate research, then the initiative must be taken to conduct actual research.

These articles will provide sufficient data to support the implementation of the plan.

The next step will be to implement the plan into a pilot practice change.

If the intervention is successful, it must be applied at the chosen organization.

To control asthma in school-based intervention, it is necessary to have all the relevant information.
