Determining the Credibility of Evidence and Resources

In practice, reliable sources inspire trust by providing solid evidence to back up research claims. Implementation of evidence-based practice (EBP) refers to the utilization of the best, most accurate, presently accessible, and relevant research findings, opinions of experts, standard guidelines, and books in clinical decision-making practice (Dagne et al., 2021). Proposing an evidence-based approach can be utilized to justify and design new studies and solve problems encountered (Lund et al., 2020). This paper will focus on the importance of evidence-based practices for patients with asthma.

Asthma from Evidence-Based Practice  

Asthma can be regarded as a collection of immunological illnesses that assault the respiratory system since it affects the human respiratory system. The main problem of asthma is shortness of breath, coughing, and chest tightness (Kurniawan et al., 2022). Asthma is a known persistent inflammatory condition. In general, asthma has two categories: childhood-onset asthma and late-onset asthma (Hammad et al., 2021). The heterogeneous nature of asthma has been revealed during studies of clinical features through unsupervised clustering methodologies. The rise in patients with asthma and its related risks supports the vital importance of implementing evidence-based practices in the treatment diagnosis of chronic conditions of asthma.

Asthma has demonstrated major patient-specific differences related to age of onset, associated risk factors, treatment response, and severity levels (Wu et al., 2019). These complexities within the disease require evidence-based practices to ensure that the best, relevant, and credible information is used for patient treatment. The fundamental goal of evidence-based practices is to ensure that individuals receive good care through proven strategies in the past. By improving patient outcomes and elevating the overall quality of care, evidence-based practices play a pivotal role in advancing healthcare standards for individuals struggling with this chronic condition.

Criteria to Determine the Credible Source

EBP is used by nurses in their line of work to determine the reliability of the articles they have chosen and to reduce medical errors in their practices because the patient’s life is at stake. To determine the credible source to use EBP in nursing practice, a CRAAP test is useful, which is an acronym for currency, relevance, authority, accuracy, and purpose (Lowe et al., 2021). This five-letter test is used to analyze if resources are up-to-date with the time, if the source is relevant to the research topic if it is authorized by credible writers and journals, whether the claims are well-supported with scholarly evidence, and if the purpose of the study is significant and clear for the audience. 

To understand the CRAAP criteria, take an example. A study by Wu et al. (2019) published in the American Journal of Respiratory and Critical Care Medicine fulfills the criteria of CRAAP by – currency (the article is within five years gives the durability of an article based on current practice), relevance (the title and the data presented in the article are directly related to the topic of interest that is asthma), authority (authors belonged to healthcare have extensive expertise on a related topic), accuracy (the accuracy of this article is proved by the fact that previous investigations adequately support data presented in this article), purpose (it is evident by the article that the objective of this article is obvious and significant to the targeted audience). 

Analyze the Credibility and Relevance of the Evidence

Healthcare practitioners can learn and gain information from the academic research on asthma used in this work to improve their practices by incorporating evidence-based practice. For example ; The article by Kurniawan et al. (2022) is a credible source as it fulfills the CRAAP criteria. This article is within five as it is last year’s study. It is relevant because the article’s topic, Asthma, is related to the title and data by providing information about asthma and its symptoms. Authorized by credible authors and journals.

It has accuracy as it mentioned the previous research data by relating current research. The purpose of this article is to help nurses by giving EBR. Another article by Hammad et al. (2021) fulfills the CRAAP criteria as this is a two-year-old paper. Providing information about asthma and its types shows the relevancy of the title and context. It contains previous articles’ data related to current research. It aims to help healthcare professionals understand asthma and its type and how to deal with it by using evidence-based practice.

Evidence-Based Practice Model

Incorporating evidence-based research information into evidence-based practice (EBP) models effectively applies research findings to clinical practice. These models provide a structured framework that healthcare professionals can follow to ensure their clinical decisions and involvements are based on the best available evidence. Mentioning the Iowa model for nurses is very relevant here. The Iowa model is a well-established model that leads nurses through the EBP process, focusing on evidence evaluation, clinical expertise integration, and patient preferences and values. Incorporating credible evidence into the Iowa model will provide specific and detailed guidance for nurses on effectively utilizing evidence-based research in their clinical practice. This can enhance the understanding and implementation of EBP among healthcare professionals (Chiwaula et al., 2021).

The Iowa Model and other EBP frameworks clearly distinguish between implementation methods and the EBP processes involved in using evidence to inform care decisions. The steps involved in the Iowa model integrated for our chosen diagnosis include: 1) finding a healthcare problem, such as asthma, within the organization by collecting the data about prevalence, 2) analyzing the severity of this problem by finding the number of cases reported in the certain months, 3) creating a team of professional experts for discussion and collaboration on the issue, 4) finding the evidence through the credible resources using the CRAAP criteria, 5) Critical thinking and reasoning on the new practice or modification in the current practice, 6) Implementation of the new practice or modification in the current practice, 7) analysis of results whether we are getting the desired results or not (Cullen et al., 2022).


In conclusion, implementing evidence-based practice (EBP) refers to utilizing the best, most accurate, presently accessible, and relevant research findings that healthcare professionals use in their practices. They use EBP to treat asthma as it is a chronic disease. Several EBP models have been created, including the Iowa model for nurses. These EBP improved the practice of nurses and patient health.
