Description of the Search Method

The search method included an electronic search that entailed the use of the CINAHL and Ebscohost databases. While both databases yielded searches that were important to my paper, the Chamberlain Library Database was the most efficient through the use of CINAHL Complete. The search targeted the scholarly articles that are English based and published within the last ten years. The two databases combined yielded more than 300 articles narrowing down to pediatric health. Restricting the articles to the last ten years and choosing the peer-reviewed articles resulted in more than 100 articles. However, at least ten articles were a perfect fit for my paper. There was the freedom to choose articles that would best facilitate the completion of the research paper. The CINAHL database was convenient as it offered all the details about the author making it easy to prove the author’s credibility. The internet also proved instrumental in searching for the summarized articles in the databases with their full versions in the online publications. The following are the keywords used in the search;

Among the articles, some were systemic reviews, while others were qualitative and quantitative studies.

Summary of the used Research Studies

The first article, as authored by Dharmage, Perret, and Custovic (2019), explored the epidemiology of asthma among children and adults. The key findings from this article were that asthma often begins during childhood with a recurrence in adulthood. However, some people do not have asthma during their childhood and encounter the condition as adults. The type of evidence, as presented in the article, is systematic reviews that involved the review of large volumes of data into one document. The article found that there was a continuation of the global asthma epidemic, especially in low-income countries. However, the rates have declined in the high-income countries. The article did not incorporate any sample or data collection methods. It also does not highlight any challenges that could have been encountered in the synchronization of the information therein. The limitation of the study lies in the environmental factors associated with the surge in asthma cases. The authors highlighted the role of the environmental factors in the etiology of asthma as remaining a mystery.

The second article, as authored by Ferrante and La Grutta (2018), studied the burden of pediatric asthma. The article’s determination was the increasing prevalence of asthma in the world at large. The children in low and medium-income countries (LMICs) suffered high mortality and morbidity compared to those in high-income countries. The article was a systematic review. The article found that despite the efforts towards asthma yielding desired results, there exists are disparities between countries as indicated by the number of asthma cases. The article does not include any sample or data collection methods. The limitation of the strategy associated with the adoption strategies. Only a few countries had asthma strategies, with the proportion being lower among the low-income countries that recorded high asthma cases.

The third article by Herzog and Cunningham-Rundles (2011) explored pediatric asthma by studying its history, treatment, and assessment methods. Just like the others, it is a systematic review. The key determination is the difference in asthma prevalence among white and black children. Asthma prevalence stood at 3.0% among the white children and 7.2% among the black children. Even when the environmental, parental, and demographic factors were under control, the black children were 2.5% more likely to experience asthma-related emergencies than their white counterparts. The article does not have any research methods and does not have a sample. The limitation of the study is the inability of the current medical practices to change the natural history of the disease. The article concludes by highlighting the continuing research on the association of the genetic susceptibility factors with the modifier genes in asthma.

Validity of Research

The external validity in the systematic reviews would measure the possibility of the generalization of the results to infer the world’s situation. The information from the three articles measure up to the situation in most countries and, hence, reflect the world’s situation. The data on the disparities in the asthma prevalence rates among the low and medium-income countries with high-income countries could apply to the different parts of the world with varying levels of income. Most global countries have a diverse population, and the differences in the asthma rates among black and white children could also apply to their population. The articles back up the claims made by providing statistical information and using credible sources. The supported claims could reflect the general world situation. The conclusion in the articles is a combination of the determination from the reviewed materials. The high number of reviewed sources depicted in the three reviews means that the holding ground is well-informed and could be a base to generalize the world’s situation. Characteristically, systematic reviews rank as part of the most reliable studies. As such, the conclusions from the three studies are reliable enough to generalize the real world’s situation.
