Determining the Credibility of Evidence and Resources

Hypertension, commonly known as high blood pressure, is a prevalent health issue affecting millions globally. Its management requires consistent monitoring, accurate treatment protocols, and a deep understanding of patient needs. The ever-evolving medical research landscape necessitates an evidence-based approach to ensure the most effective and contemporary interventions are utilized. In the subsequent sections, we will delve into the importance of evidence-based practices, methodologies to evaluate credibility, and the role of nursing models in the holistic management of hypertension.

Evidence-Based Approach for Hypertension Management 

Hypertension is a chronic condition of high blood pressure exceeding 140/90 mmHg. This chronic healthcare issue predominantly affects older segments of the population, but younger adults can also be susceptible. Hypertension accounted for causing 691,095 deaths in the U.S. in 2021. Moreover, 45 % of U.S. natives have uncontrolled hypertension, making a population of 37 million U.S. adults with hypertension (CDC, 2023).

Hypertension is considered a silent killer as it shows no significant symptoms and can only be diagnosed by measuring blood pressure. Therefore, routine blood pressure examination is essential to diagnose hypertension in patients. Hypertension treatment requires implementing protocols and guidelines to decide the therapeutic plan for patients. Considering the plethora of information available on hypertension, nurses must determine the credibility of evidence and resources.

Additionally, they must practice the evidence-based guidelines on hypertension to ensure patients acquire adequate treatment at the required time. Hypertension management is needed to prevent the onset of lethal cardiovascular diseases such as stroke, heart attack, and kidney disorders. Therefore, it is essential to consider evidence-based practices (EBP) for effective and timely management of hypertension that saves patients from life-threatening conditions (Fuchs & Whelton, 2019). 

Criteria to Determine Credibility of Resources

The CRAAP methodology is a criterion to evaluate the authenticity and credibility of journals, websites, and article resources. The CRAAP criterion is an acronym for Currency, Relevance, Authority, Accuracy, and Purpose. This methodology shares valuable pieces of information on the credibility of resources.

For instance, it describes whether the source has been updated and published lately and if it shares insights on the topic under consideration, showing its relevance. Moreover, it tells about the authors and their credibility, the accuracy of claimed points with scholarly references, and the purpose of the journal and article under study, if it brings valuable data or results for the audience. One way to apply this criterion can be done by considering the following bibliography as an example:

Li, R., Liang, N., Bu, F., & Hesketh, T. (2020). The effectiveness of self-management of hypertension in adults using mobile health: Systematic review and meta-analysis. JMIR MHealth and UHealth, 8(3), e17776.

Currency: The article mentioned above was published in 2020, falling in the category of the latest articles within the past five years. Relevance: This journal article is specifically related to hypertension and its self-management. Authority: The authors are well-equipped with scientific knowledge of hypertension and have scientific and medical backgrounds in their fields. Accuracy: The claims are well-supported by evidence-based references in this journal article. Purpose: This study aims to provide the audience with results on whether self-management is effective for hypertension using mobile health.

Analysis of Credibility and Relevance of Evidence and Resources

This section entails some evidence-based resources on hypertension to analyze their credibility and relevance with the CRAAP test. One study on hypertension management was conducted by Timpel et al. (2020) on managing hypertension through telemedicine. This source was published within the last five years, showing its currency and relevance to hypertension. Moreover, the authors share their knowledge on treating hypertension by using technology where patients can acquire consultation on managing hypertension remotely.

The article is published in the Journal of Medical Internet Research, which publishes peer-reviewed papers. The authors are specifically from medical backgrounds, where they presented accurate results and findings. Lastly, this study aims to brief the audience on managing hypertension using telehealth and telemedicine.

Another literature study by Mostafa et al. (2022) highlights antihypertensive effectiveness in controlling hypertension, i.e., Perindopril and Amlodipine. This study was first published in 2022 and fulfills the criterion of currency in the CRAAP test. Moreover, the study mainly talks about hypertension management, showing its relevance to the topic of discussion.

The authors are acquainted with medical background and furnished information substantiated sufficiently with scholarly references. The purpose is to manage hypertension using anti-hypertensive agents and their efficacy. Based on the analysis, the most helpful resource is the study conducted by Mostafa and colleagues, as it directly mentions pharmacological ways to control hypertension and prevent lethal cardiovascular diseases.

Importance of Evidence-Based Practice Model

Nurses use evidence-based practice models to incorporate credible evidence to address various healthcare issues. Several evidence-based practice models exist in the literature, including Johns Hopkins, Stetler, and Iowa. These EBP models help nurses make informed decisions based on the evidence available. Moreover, integrating evidence-based data into these models promotes the delivery of effective care treatments by identifying relevant interventions.

This will lead to better patient health outcomes and efficient use of resources. Additionally, this will result in cost-effective care treatments as healthcare providers make informed decisions based on evidence incorporated into EBP models.

The Johns Hopkins Nursing Model comprises three key steps: identification of practice question (effective hypertension management), gathering evidence (literature on hypertension treatment), and Translation (plan hypertension treatment, implement them and evaluate results, and communicate with an interdisciplinary team for managing hypertension) (Rice, 2023). The literature will be located for hypertension management, and evidence will be gathered.

After gathering data on the treatment of hypertension, the plan for hypertension management is developed, considering various factors such as patient health needs and preferences and cultural sensitivity while merging clinical expertise. The extended plan for hypertension management is implemented, and monitoring is conducted to evaluate outcomes. The outcomes are thoroughly discussed to revise the plan and improve patient health outcomes. Through this model, nurses can deliver high-quality care to hypertensive patients and enhance their quality of health.


Hypertension requires long-term care treatment and management for which an evidence-based approach is the best-suited strategy. With this strategy, patients can effectively manage their blood pressure and prevent themselves from lethal diseases that occur, leaving it untreated.  The CRAAP test criterion is an effective methodology to determine resources’ credibility and provides hypertension management information.

Various hypertensive relevant studies are analyzed through this criterion that can be useful in treating this healthcare problem. Furthermore, the John Hopkins model is one of the EBP models that nurses can use to integrate hypertensive-related evidence to make informed decisions for hypertensive patients. This will improve health outcomes and quality of life.
