The Second Phase Of Evidence Base Practice Is The Literature Search T

The second phase of evidence-base practice is the literature search. This is the phase in which you find the evidence to either support a change in practice or to be led into further research. Equipped with your PICO question you will begin searching for existing studies that have been conducted on your topic. There is a vast amount of information out there. Please refer to chapter 3 in your textbook, Gathering and Appraising the Literature for skills and tools to help you in your search.

Table 3.2 (p. 51), Table 3.3 (p. 53), and Table 3.4 (p. 56) provide guidelines and databases for your search. Please remember many of these databases are included in your library resources made available to you through PHSSN and your parent university. As you do your literature search, please keep in mind the hierarchy of evidence. The systematic reviews and meta-analyses will provide the strongest evidence, so you will want to focus on finding those types of studies.

The next strongest level of evidence will be your randomized controlled studies and so forth. Gather 4-7 research articles on your topic. It is often helpful to simply review the abstracts of articles initially in selecting the articles, and later you can go through the articles more comprehensively. Appraise your articles for relevancy, validity, and reliability. Please use current articles, published within the last 5-7 years.

The process of evidence-based practice (EBP) is fundamental to ensuring that healthcare decisions are grounded in the most current and reliable scientific evidence. Among its various phases, literature searching stands out as a critical step in identifying relevant research that can inform practice changes or highlight areas needing further investigation. This phase involves an organized search for high-quality studies that address the clinical questions formulated in the earlier stage of EBP, often articulated via the PICO framework—Population, Intervention, Comparison, and Outcome.

The initial step in an effective literature search begins with a clear understanding of the research question, such as whether pregnant women who smoke are at a higher risk of miscarriage compared to those who do not smoke. Using tailored keywords aligned with the PICO components—such as “pregnancy,” “smoking,” “tobacco,” and “addiction”—helps narrow down the vast array of available literature. The search should be guided by established guidelines and utilizing specific databases, many of which are accessible through institutional and university libraries, including those outlined in resources like Tables 3.2, 3.3, and 3.4 of the textbook “Gathering and Appraising the Literature” (Chapter 3).

While searching for literature, it is essential to prioritize high-quality evidence, which is often classified based on the hierarchy of evidence. Systematic reviews and meta-analyses, ranking at the top, synthesize numerous studies and provide comprehensive insights into the association between smoking during pregnancy and miscarriage risk. Randomized controlled trials (RCTs) follow closely in strength of evidence and are invaluable for establishing causal relationships and testing interventions. Observational studies, such as cohort and case-control studies, also contribute important insights, particularly when controlled trials are infeasible or unethical in the context of certain exposures like smoking.

Given the wealth of information, it is advisable to initially review abstracts to filter studies based on relevance and quality. Selecting between four to seven research articles helps maintain manageability while ensuring sufficient breadth for a reliable synthesis of evidence. Critical appraisal of these articles should focus on their relevance to the PICO question, methodological rigor, validity, and reliability. Current literature, ideally published within the last five to seven years, ensures that the findings reflect the latest research and best practices.

In this context, literature examining the correlation between smoking and miscarriage is particularly pertinent. For instance, Niara’s meta-analysis (Year) highlights a significant association between tobacco exposure and increased miscarriage risk. Additionally, Wendy’s article (Year) discusses the challenges of addressing tobacco use during pregnancy and strategies to promote cessation, which are vital for clinical application. A comprehensive review of such studies enables clinicians to base their practice on strong evidence, ultimately improving patient outcomes.

In conclusion, the literature search phase in EBP requires systematic planning, strategic keyword use, and critical evaluation of sources to ensure the integration of the highest quality evidence. Focusing on recent, peer-reviewed systematic reviews, meta-analyses, and randomized trials provides a robust foundation for making informed clinical decisions regarding pregnant women and smoking-related miscarriage risk.
