Literature evaluation is an essential aspect of the Evidence-Based Project (EBP) as it sheds light on the topic with findings from current research. When analyzing the literature associated with my EBP, a few gaps were identified. Most studies were carried out using smaller samples that may not guarantee the true reflection of the entire population. Some studies were carried out strictly in rural or urban settings which may have children with different characteristics or learning abilities. While other studies considered eliminating children with parents who worked in healthcare settings that could influence their understanding on the importance hand hygiene (HH) some of them did not eliminate them hence an inaccurate reflection of the effect of HH education among elementary school children. Researchers need to be cognizant of the fact that a small sample size may not give a true reflection of the research findings therefore, there is need to have an adequate sample size. More et al. (2022) recommended the need to carry out the study on a larger sample to get a generalized view on the population. In addition to this, researchers need to purposefully select their sample bearing in mind the variables that may affect the reliability of the study findings such as level of education or knowledge. Klar et al. (2022) recommended that research involving children should be increased. I gathered that ensuring research that focuses on elementary school children should be a driving factor to the researchers. Finally, the location of the study must be considered bearing in mind how it affects the overall outcome of the study.
