Essentials Of Evidence-Based Practice

Evidence-based nursing practice frequently uses PICO (T), a procedure that is frequently used in evidence-based practice to frame, ask, and respond to a question regarding the health-related inquiry. Another piece of evidence-based study also makes use of it. The P represents a population, which can include people of a certain age, sex, or ethnicity; the I stands for an implemented intervention; the C is the comparison; the O is the outcome; and the T is the study’s time frame (Melnyk & Fineout- Overholt, 2015). It can be applied to illness epidemiology, research interpretation, diagnosis procedures, and disease etiology. My PICO question is, “How does handwashing with soap and water minimize the incidence of nosocomial infections among healthcare personnel in the emergency room compared to the usage of hand sanitizer during eight months?” Below is a list of the population, intervention, comparison, and result:

P- Medical personnel in emergency rooms

I- Washing hands with water and soap.

C-Using hand sanitizers

O- Lower the potential for nosocomial infections

T-Six months,

Infections acquired in hospitals are one of the issues facing the nation’s healthcare system. Patients, relatives, and healthcare providers are all impacted by this. Only healthcare facilities can provide for the acquisition of nosocomial illnesses, often known as hospital-acquired infections. Pneumonia and urinary tract infections are the most prevalent of these illnesses. If poorly managed or complicated, these infections can have adverse effects on the genitourinary and respiratory systems in addition to other systems. These illnesses are caused by a variety of macro- and microorganisms. Pseudomonas aeruginosa is the most prevalent bacterial organism because it can survive and adapt in a variety of habitats, including soil, water, sewage, and hospitals. As a result, this opportunistic pathogen is the most common cause of nosocomial infection (Zaher Ali & Nusrat munitaz, 2015).

In the Walden Library, the following databases were searched: PubMed, CINAHL, CINAHL & MEDLINE Combined Search. A date range of 2015 to 2020 (5 years) was used to show the most recent papers in evidence-based practice after I focused my search on peer review. An advanced search was used for PubMed, and the article was filtered to focus the search. Only articles involving human subjects that were released between 2015 and 2020 were filtered. Also, I used a function of PubMed called Clinical Queries as a further tactic. The best answers to clinical issues are given by clinical inquiries, which employ an organized search, critical evaluation, reliable suggestions, a clinical perspective, and rigorous peer review. The best evidence for use at the point of care is delivered by clinical inquiries. Clinical Inquiries relate the type of query (treatment, diagnosis, etiology, and prognosis) to a saved search strategy that fetches the proper research technique in order to enhance search results (Schardt, 2007). The search results that will be utilized to locate significant peer-reviewed papers will be improved with the use of these strategies. I immediately added a filter and conducted a phrase search. I received over 212 hits when I added my filters and searched “Hospital Acquired Infection” in the Walden Library. The school advises pupils to use Boolean terms to narrow their search and provide more pertinent results (Walden Library, 2020). The second I inserted the Boolean terms, I received over 84,623 results. Also, a study found that in order to find about 90% of the pertinent material, it is critical to search at least three separate databases. Using alternative terms is another method to improve the rigor and efficacy of a database search (Ho et al., 2016). Other phrases, such as “Nosocomial infection,” “Proper hand hygiene,” or “Hand sanitizers,” can be used to enhance search results and increase the likelihood of relevant evidence-based rese

Describe your search results in terms of the number of articles returned on original research and how this changed as you added search terms using your Boolean operators. Finally, explain strategies you might make to increase the rigor and effectiveness of a database search on your PICO(T) question. Be specific and provide examples.
