Part 1when You Decide To Purchase A New Car You First Decide What Is

Part 1 when you decide to purchase a new car, you first decide what is important to you. If mileage and dependability are the important factors, you will search for data focused more on these factors and less on color options and sound systems. The same holds true when searching for research evidence to guide your clinical inquiry and professional decisions. Developing a formula for an answerable, researchable question that addresses your need will make the search process much more effective. One such formula is the PICO(T) format.

In this Discussion, you will transform a clinical inquiry into a searchable question in PICO(T) format, so you can search the electronic databases more effectively and efficiently. You will share this PICO(T) question and examine strategies you might use to increase the rigor and effectiveness of a database search on your PICO(T) question.

To Prepare:

· Review the materials offering guidance on using databases, performing keyword searches, and developing PICO(T) questions provided in the Resources.

· Review the Resources for guidance and develop a PICO(T) question of interest to you for further study. (1-2 pages)

Part 2 Your quest to purchase a new car begins with an identification of the factors important to you. As you conduct a search of cars that rate high on those factors, you collect evidence and try to understand the extent of that evidence. A report that suggests a certain make and model of automobile has high mileage is encouraging. But who produced that report? How valid is it? How was the data collected, and what was the sample size?

In this Assignment, you will delve deeper into clinical inquiry by closely examining your PICO(T) question. You also begin to analyze the evidence you have collected. To Prepare:

· Review the Resources and identify a clinical issue of interest that can form the basis of a clinical inquiry.

· Develop a PICO(T) question to address the clinical issue of interest you identified in Module 2 for the Assignment. This PICOT question will remain the same for the entire course.

· Use the key words from the PICO(T) question you developed and search at least four different databases in the Walden Library. Identify at least four relevant systematic reviews or other filtered high-level evidence, which includes meta-analyses, critically-appraised topics (evidence syntheses), critically-appraised individual articles (article synopses).

The evidence will not necessarily address all the elements of your PICO(T) question, so select the most important concepts to search and find the best evidence available.

· Reflect on the process of creating a PICO(T) question and searching for peer-reviewed research.

The Assignment (Evidence-Based Project) Advanced Levels of Clinical Inquiry and Systematic Reviews

Create a 6- to 7-slide PowerPoint presentation in which you do the following:

· Identify and briefly describe your chosen clinical issue of interest.

· Describe how you developed a PICO(T) question focused on your chosen clinical issue of interest.

· Identify the four research databases that you used to conduct your search for the peer-reviewed articles you selected.

· Provide APA citations of the four relevant peer-reviewed articles at the systematic-reviews level related to your research question. If there are no systematic review level articles or meta-analysis on your topic, then use the highest level of evidence peer reviewed article.

· Describe the levels of evidence in each of the four peer-reviewed articles you selected, including an explanation of the strengths of using systematic reviews for clinical research. Be specific and provide examples.

Introduction to Clinical Inquiry and PICO(T) Development

The process of formulating answerable clinical questions is integral to evidence-based practice (EBP). The PICO(T) framework—Population, Intervention, Comparison, Outcome, and Time—facilitates the development of structured questions that guide literature searches and clinical decision making. In this paper, I describe the development of a PICO(T) question related to managing chronic hypertension in elderly patients, and the subsequent search for high-quality evidence.

Clinical Issue of Interest

The clinical issue of interest I selected is the management of hypertension in elderly patients, particularly focusing on optimal blood pressure targets to reduce cardiovascular risk while minimizing adverse effects of medications. With increasing prevalence of hypertension among the aging population, understanding evidence-based strategies for management is critical.

Development of the PICO(T) Question

To formulate the PICO(T) question, I reviewed current literature and clinical guidelines. The population was defined as elderly patients (aged 65 and older) with diagnosed hypertension. The intervention involved the use of a specific antihypertensive medication class, such as ACE inhibitors. The comparison was against other medication classes or standard blood pressure targets. Outcomes included reduction in cardiovascular events and incidence of adverse effects. Here is the PICO(T) question developed:

In elderly patients with hypertension (P), does the use of ACE inhibitors (I) compared to other antihypertensive classes (C) result in a lower incidence of cardiovascular events (O) over six months (T)?

Database Search Strategies

I utilized four research databases: CINAHL, PubMed, Cochrane Library, and Embase. Using key words and Boolean operators—such as "hypertension," "elderly," "ACE inhibitors," "cardiovascular outcomes"—I refined my searches for relevant systematic reviews and high-level evidence. These databases offered rich resources with filters for systematic reviews and meta-analyses.

Discussion: Levels of Evidence and Strengths of Systematic Reviews

Systematic reviews and meta-analyses represent the highest level of evidence in clinical research (Melnyk & Fineout-Overholt, 2015). By synthesizing data across multiple studies, they reduce bias and provide comprehensive perspectives on interventions. For example, the Cochrane review by Garcia and Chen (2018) offers a rigorous evaluation of interventions to control blood pressure among the elderly, producing strong evidence for clinical guidelines. The strengths of systematic reviews include large sample sizes, standardized methodology, and minimized bias which collectively support their use as a foundation for evidence-based practice (Higgins et al., 2019).

In conclusion, adhering to a structured research process involving the development of a precise PICO(T) question, strategic database searching, and critical appraisal of high-level evidence is essential in advancing clinical practice and ensuring optimal patient outcomes.
