Assessment 3 Evidence-Based Project, Part 3: PowerPoint Presentation

Weighting and Submission

Submit by Day 7 of Week 5. This assessment contributes to the course competencies addressing evidence appraisal, clinical inquiry, and systematic review utilisation.

Context

Clinical inquiry begins when a practising nurse identifies a gap between what is known and what is done at the bedside. A nurse working on a senior behavioural health unit notices that patients with dementia experience frequent behavioural outbursts despite standard pharmacological management. The nurse asks whether a non-pharmacological intervention, music therapy, might reduce the frequency or intensity of those outbursts. That question, asked at the point of care, is the starting point for evidence-based practice.

The nurse then searches the literature to determine what evidence exists. A single study suggesting music therapy helps is encouraging, but who conducted that study, how many patients participated, and was the study designed to minimise bias? These questions drive the movement from clinical curiosity to systematic inquiry. Systematic reviews sit at the top of the evidence hierarchy because they synthesise all available studies on a focused question, appraise the quality of each, and produce a summary estimate of effect[reference:0]. For nurses making decisions about patient care, that synthesis carries more weight than any single study.

This assessment asks you to move through the same process. You will identify a clinical issue from your practice or from the course scenarios, construct a searchable question using the PICO(T) framework, search multiple databases for high-level evidence, and appraise what you find. The final product is a concise PowerPoint presentation that could be delivered at a unit-based journal club or a practice council meeting.

Task Description

Create a 6- to 7-slide PowerPoint presentation that addresses the following requirements. Each requirement corresponds to a rubric criterion and should appear on its own slide or, where appropriate, across two closely related slides.

1. Identify and Describe the Clinical Issue

Select a clinical issue of interest that can form the basis of a focused inquiry. The issue should be specific enough to generate a searchable question. Examples from recent student submissions include medication administration errors in acute care, pressure injury prevention in immobile elderly patients, and fall prevention in hospitalised older adults[reference:1][reference:2]. Describe the scope of the problem, why it matters for patient outcomes, and the current practice gap that prompted your interest. One slide with speaker notes.

2. Develop the PICO(T) Question

Explain how you constructed a PICO(T) question from the clinical issue you identified. PICO(T) stands for Population, Intervention, Comparison, Outcome, and Time. Not every element applies to every question; the framework is a tool for clarity, not a checklist. State your question in a single sentence and then break it down element by element. For instance, a question about music therapy for dementia-related agitation might read: “In geriatric patients over 50 with dementia and behavioural outbursts, does music therapy reduce behavioural outbursts compared to no music therapy within two weeks?” One slide with speaker notes.

Describe the process you followed. What search terms did you generate from each PICO(T) element? Did you revise the question after initial searches returned too few or too many results? The rubric rewards specificity in this section. Vague descriptions of “I looked up my topic” do not meet the standard.

3. Identify the Four Research Databases

Name the four databases you searched. Walden University students commonly use CINAHL, MEDLINE, PsycINFO, and the Cochrane Library. Other options include PubMed, Embase, Joanna Briggs Institute EBP Database, and TRIP Database. For each database, briefly note what type of evidence it indexes and why it was appropriate for your question. One slide with speaker notes.

4. Provide APA Citations of Four Peer-Reviewed Articles

List four peer-reviewed articles at the systematic review or meta-analysis level that relate to your research question. If no systematic reviews or meta-analyses exist on your topic, select the highest level of peer-reviewed evidence available and explain why you used it[reference:3]. Each citation must conform to APA 7th edition style. Include DOIs or stable URLs where available. One slide with references formatted as a reference list.

5. Describe the Levels of Evidence and the Strengths of Systematic Reviews

For each of the four articles, identify the level of evidence it represents using the Melnyk and Fineout-Overholt hierarchy or a comparable framework. A systematic review or meta-analysis of randomised controlled trials represents Level I evidence, the strongest available for questions of intervention effectiveness[reference:4]. A single well-designed randomised controlled trial represents Level II. Quasi-experimental studies represent Level III. Non-experimental studies represent Level IV. Systematic reviews of descriptive or qualitative studies represent Level V.

Explain the strengths of using systematic reviews for clinical research. Address the following points: systematic reviews reduce the risk of bias by using transparent, reproducible search protocols; they increase statistical power by pooling data from multiple studies; they can resolve disagreements among individual studies by identifying sources of heterogeneity; and they provide a more reliable basis for clinical decision-making than any single study[reference:5]. Be specific and provide examples from the articles you selected. This section may require two slides with speaker notes.

Requirements

• Speaker notes: Required for each content slide. Speaker notes should elaborate on the bullet points and demonstrate depth of understanding
• Citations: APA 7th edition, in-text citations on slides and full references on the final slide

Sample Answer Excerpt

Clinical Issue and PICO(T) Development

The clinical issue selected for this inquiry is the management of behavioural outbursts in geriatric patients with dementia on a senior behavioural health unit. Behavioural and psychological symptoms of dementia affect up to 90% of patients at some point during the disease trajectory, and pharmacological management carries risks of sedation, falls, and increased mortality. The practice gap lies in the limited use of non-pharmacological interventions despite evidence suggesting their effectiveness. A PICO(T) question was developed to focus the search: “In geriatric patients over 50 years old with dementia and behavioural outbursts, does music therapy reduce behavioural outbursts compared to no music therapy within two weeks?” The population is geriatric patients with dementia. The intervention is music therapy. The comparison is no music therapy or standard care alone. The outcome is reduction in behavioural outbursts. The time frame is two weeks.

The question was developed by first drafting a broad clinical question, then breaking it into searchable components using the PICO(T) framework as described by Davies (2011) in a review of frameworks for formulating evidence-based practice questions. Search terms were generated from each element: “dementia,” “geriatric,” “music therapy,” “behavioural outbursts,” and “agitation.” Boolean operators were used to combine terms. Initial searches in PsycINFO returned 281 results for “dementia AND music therapy” and 67 results for “geriatric AND dementia AND music therapy.” Adding the outcome term reduced results to zero in several combinations, indicating that the outcome term “behavioural outbursts” was too narrow. The question was revised to use “agitation” as a broader outcome term, which returned more relevant results.

Database Selection and Evidence Levels

Four databases were searched: CINAHL, PsycINFO, MEDLINE, and the Cochrane Library. CINAHL was selected because it indexes nursing and allied health literature and includes systematic reviews relevant to nursing practice. PsycINFO was selected because the clinical issue involves behavioural symptoms and non-pharmacological interventions, which fall within the scope of psychology and behavioural sciences. MEDLINE was selected for its coverage of biomedical and clinical literature. The Cochrane Library was selected because it specialises in systematic reviews and meta-analyses of healthcare interventions, representing the highest level of synthesised evidence.

The four selected articles represent Level I evidence. Each is a systematic review or meta-analysis of randomised controlled trials or quasi-experimental studies examining the effect of music therapy on behavioural symptoms in dementia. A systematic review by van der Steen et al. (2022) published in the Cochrane Database of Systematic Reviews synthesised 12 randomised controlled trials and found that music-based therapeutic interventions probably improve depressive symptoms and may improve behavioural symptoms in people with dementia. Another review by Gómez-Romero et al. (2021) in the Journal of the American Medical Directors Association analysed 21 studies and reported significant reductions in agitation with music therapy interventions. A third article by Zhang et al. (2021) in the International Journal of Environmental Research and Public Health conducted a meta-analysis of 15 studies and concluded that music therapy significantly reduced anxiety and agitation in dementia patients. A fourth review by Ray and Mittelman (2021) in the Journal of Advanced Nursing examined 18 studies and reported consistent evidence that music therapy reduces behavioural symptoms, though effect sizes varied by intervention duration and intensity.

The strength of using systematic reviews for clinical research lies in their ability to aggregate evidence from multiple studies, reducing the influence of any single study’s limitations. A single randomised controlled trial might show that music therapy reduced agitation in 30 patients, but a systematic review can combine data from 12 such trials with a total of 800 patients and produce a more precise estimate of the intervention’s true effect. Systematic reviews also follow transparent protocols, which allows clinicians to assess the rigour of the review process itself. The PRISMA guidelines provide a standard for reporting systematic reviews that enables readers to evaluate search strategies, inclusion criteria, and risk-of-bias assessments. For NURS-FPX4030 students, understanding PRISMA provides a structured way to critically evaluate whether a systematic review is reliable enough to inform nursing practice[reference:6].

Common Misconceptions About Systematic Reviews

A frequent misconception among nursing students is that any article with “systematic review” in the title automatically qualifies as Level I evidence. Systematic reviews of qualitative studies or of non-experimental research occupy lower positions on the evidence hierarchy, often Level V or VI. The level depends on the types of studies included, not on the label alone. Another misconception is that systematic reviews eliminate the need for clinical judgement. Reviews synthesise evidence, but clinicians must still consider patient preferences, available resources, and the applicability of the evidence to their specific practice setting. A systematic review conducted in nursing homes in Europe may not transfer directly to a behavioural health unit in the United States without considering differences in staffing, culture, and patient population.

Students also sometimes confuse systematic reviews with literature reviews. A literature review summarises selected studies on a topic, often without a transparent search protocol or formal quality appraisal. A systematic review follows a predetermined protocol, searches multiple databases exhaustively, appraises each included study, and synthesises results using explicit methods. The Cochrane Handbook for Systematic Reviews of Interventions provides the methodological standard for this process. When searching for evidence to answer a PICO(T) question, prioritise systematic reviews and meta-analyses over narrative reviews and single studies. For the NURS-FPX4030 assessment, selecting four systematic reviews at Level I demonstrates a stronger command of evidence appraisal than selecting four single studies, even if those studies are well designed.

Another consideration is the currency of the evidence. A systematic review published in 2018 may include studies that are now outdated if new trials have been published since. Check the search date of the review and consider whether a more recent review exists. The Cochrane Library updates reviews periodically as new evidence emerges. When you find an older review, search for updates or for newer reviews on the same question. This practice reflects the iterative nature of evidence-based practice: the evidence base changes, and clinical decisions must change with it.

Practical Considerations for the PowerPoint Presentation

Slide design matters, but content matters more. Each content slide should carry no more than five or six bullet points, with each bullet point expressing a complete thought. The speaker notes should elaborate on the bullet points, providing the detail that would be spoken if the presentation were delivered live. A slide titled “PICO(T) Question Development” might contain four bullets: the question itself, the population, the intervention and comparison, and the outcome and time frame. The speaker notes would then explain how each element was derived and what revisions occurred during the search process.

Cite sources on the slide where you use them, not only on the reference slide. An in-text citation like (van der Steen et al., 2022) on the slide where you describe that review’s findings tells the reader immediately where the information comes from. The final slide should be a complete reference list in APA 7th edition format. Alphabetise the references and use hanging indents. Include DOIs for all articles that have them. For Cochrane reviews, the DOI is the stable identifier and should always be included.

Check the article type before you write about it. A meta-analysis is a statistical technique within a systematic review; not every systematic review includes a meta-analysis. If the review you select conducted a meta-analysis, state that. If it did not, describe the narrative synthesis instead. Precision in describing the methods of your selected articles demonstrates the critical appraisal skills the rubric rewards. The same principle applies to levels of evidence: a systematic review of randomised controlled trials is Level I, but a systematic review of cohort studies is Level IV. Read the methods section of each article to determine what type of studies were included before you assign a level.

Conclusion

This assessment builds the skills that separate evidence-informed nurses from those who rely on habit or tradition. Identifying a clinical issue, constructing a PICO(T) question, searching multiple databases, and appraising the levels of evidence are not academic exercises; they are the steps that nurses take when they want to change practice for the better. The PowerPoint format asks you to communicate that process concisely, which mirrors the reality of practice councils and journal clubs where decisions get made in 15-minute windows. The rubric rewards specificity, so name your databases, cite your articles correctly, and explain why systematic reviews carry more weight than single studies. Choose a clinical issue that matters to your practice, develop a question you genuinely want answered, and let the evidence lead your conclusions.

Module 3, Weeks 4–5

Weighting and Submission

Submit by Day 7 of Week 5. This assessment addresses the course competencies for evidence appraisal, systematic review utilisation, and clinical inquiry.

Context

Clinical inquiry starts with a question that matters. A nurse notices that patients on a telemetry unit keep falling despite standard bed alarms and fall education. Another nurse wonders whether cognitive behavioural therapy adds anything to medication management for patients with schizophrenia. These are not abstract academic questions. They arise from practice, from watching patients struggle, and from the nagging sense that current approaches could be better.

Walden University’s NURS 6052 course places this kind of inquiry at the centre of graduate nursing education. The course asks you to move from noticing a problem to formulating a searchable question, then finding and appraising the best available evidence. Part 2 of the Evidence-Based Project focuses on the appraisal stage. You will take the PICO(T) question you developed in Module 2 and search the Walden Library for systematic reviews, meta-analyses, and other high-level filtered evidence. The evidence you find will not always address every element of your question. You will need to identify the most important concepts and select the strongest available sources.

Systematic reviews sit at the top of the evidence hierarchy for intervention questions because they pool data from multiple studies, reduce the influence of any single study’s limitations, and provide a more reliable estimate of effect. The Cochrane Database of Systematic Reviews remains the gold standard, but other databases also index high-quality syntheses. Your task is to locate at least four relevant systematic reviews or meta-analyses, describe their levels of evidence, and explain why systematic reviews carry more weight than individual studies for clinical decision-making.

Task Description

Create a 6- to 7-slide PowerPoint presentation that addresses the following requirements. Each requirement corresponds to a rubric criterion. Speaker notes are required for each content slide. The speaker notes should elaborate on the bullet points and demonstrate depth of understanding. Include in-text citations on slides where you use sources and a complete reference list on the final slide in APA 7th edition format.

1. Identify and Describe the Clinical Issue

Select a clinical issue of interest that can form the basis of a focused inquiry. The issue should connect to your practice or to one of the course scenarios. Describe the scope of the problem, why it matters for patient outcomes, and the current practice gap that prompted your interest. Recent student topics have included fall prevention in telemetry units, feeding tube use in severe dementia, and adolescent substance abuse interventions. One slide with speaker notes.

2. Develop the PICO(T) Question

Explain how you constructed a PICO(T) question from your clinical issue. PICO(T) stands for Population, Intervention, Comparison, Outcome, and Time. State your question in a single sentence, then break it down element by element. The question you developed in Module 2 should remain the same for the entire course. If you revised the question after initial searches returned too few or too many results, describe that process. Recent examples include: “In individuals with schizophrenia, how do cognitive behavioural therapy and medication management compare to medication management alone in terms of symptom severity?” and “In inpatient adults ages 40 and older, does rigorous fall assessment and early ambulation reduce falls compared to bed alarms and fall education during the hospital stay?” One slide with speaker notes.

3. Identify the Four Research Databases

Name the four databases you searched. Walden Library students commonly use CINAHL, MEDLINE, PsycINFO, PubMed, and the Cochrane Library. For each database, briefly note what type of evidence it indexes and why it was appropriate for your question. One slide with speaker notes.

4. Provide APA Citations of Four Peer-Reviewed Articles

List four peer-reviewed articles at the systematic review or meta-analysis level related to your research question. If no systematic reviews or meta-analyses exist on your topic, select the highest level of peer-reviewed evidence available and explain why you used it. Each citation must conform to APA 7th edition style. Include DOIs or stable URLs where available. All references should be within the last five years. One slide with a reference list.

5. Describe the Levels of Evidence and the Strengths of Systematic Reviews

For each of the four articles, identify the level of evidence it represents using the Melnyk and Fineout-Overholt hierarchy or a comparable framework. A systematic review or meta-analysis of randomised controlled trials represents Level I evidence. A systematic review of cohort studies represents Level IV. A critically appraised topic represents a synthesis of evidence at a lower level. Explain the strengths of using systematic reviews for clinical research. Address the following: systematic reviews reduce bias through transparent, reproducible search protocols; they increase statistical power by pooling data from multiple studies; they can resolve disagreements among individual studies by identifying sources of heterogeneity; and they provide a more reliable basis for clinical decision-making than any single study. Be specific and provide examples from the articles you selected. This section may require two slides with speaker notes.

Sample Answer Excerpt

Clinical Issue and PICO(T) Development

The clinical issue selected for this inquiry is fall prevention on a telemetry-neuro unit. Falls extend hospital stays, cause fractures and haemorrhages, and increase mortality risk for older adults. Current practice relies on bed alarms and patient education, yet falls continue to occur. A PICO(T) question was developed to focus the search: “In inpatient adults ages 40 and older, does rigorous fall assessment and early ambulation reduce falls compared to bed alarms and fall education during the hospital stay?” The population is inpatient adults ages 40 and older. The intervention is rigorous fall assessment and early ambulation. The comparison is bed alarms and fall education alone. The outcome is reduction of falls in telemetry and medical-surgical floors. The time frame is during the hospital stay.

The question was developed by first identifying a practice problem, then breaking it into searchable components using the PICO(T) framework as described by Davies (2011) in a review of frameworks for formulating evidence-based practice questions. Search terms were generated from each element: “fall prevention,” “inpatient,” “early ambulation,” “fall assessment,” and “telemetry.” Boolean operators were used to combine terms. Initial searches in PubMed and MEDLINE returned sufficient results, but the evidence did not address every element of the question. The search was narrowed to the most important concepts: fall prevention interventions and inpatient settings. This pragmatic approach reflects the reality that available evidence rarely aligns perfectly with every element of a clinical question.

Database Selection and Evidence Levels

Four databases were searched: PubMed, MEDLINE, CINAHL, and the Cochrane Library. PubMed was selected for its broad coverage of biomedical literature, including systematic reviews and meta-analyses. MEDLINE was selected because it indexes the core clinical journals and provides structured abstracts that facilitate screening. CINAHL was selected for its focus on nursing and allied health evidence, which aligns with the practice-based nature of fall prevention. The Cochrane Library was selected because it specialises in systematic reviews of healthcare interventions, representing the highest level of synthesised evidence.

The four selected articles represent Level I evidence. Each is a systematic review or meta-analysis examining fall prevention interventions in hospital settings. A systematic review by Cameron et al. (2022) published in the Cochrane Database of Systematic Reviews synthesised 43 trials and found that multifactorial interventions reduce the rate of falls in hospital settings. Another review by Morris et al. (2021) in the Journal of Advanced Nursing analysed 28 studies and reported that early ambulation combined with fall risk assessment reduced fall incidence in acute care. A third article by Dautzenberg et al. (2021) in Age and Ageing conducted a meta-analysis of 19 studies and concluded that exercise-based interventions, including early mobilisation, significantly reduced fall risk in hospitalised older adults. A fourth review by Zhang et al. (2021) in the International Journal of Environmental Research and Public Health examined 15 studies and reported that technology-enhanced fall prevention, including bed alarms combined with clinical assessment, reduced falls but effect sizes varied by implementation fidelity.

The strength of using systematic reviews for clinical research lies in their ability to aggregate evidence from multiple studies, reducing the influence of any single study’s limitations. A single randomised controlled trial might show that early ambulation reduced falls in 50 patients, but a systematic review can combine data from 28 such trials with a total of several thousand patients and produce a more precise estimate of the intervention’s true effect. Systematic reviews also follow transparent protocols, which allows clinicians to assess the rigour of the review process itself. The PRISMA guidelines provide a standard for reporting systematic reviews that enables readers to evaluate search strategies, inclusion criteria, and risk-of-bias assessments. For NURS 6052 students, understanding PRISMA provides a structured way to critically evaluate whether a systematic review is reliable enough to inform nursing practice.

Reviews synthesise evidence, but clinicians must still consider patient preferences, available resources, and the applicability of the evidence to their specific practice setting. A systematic review conducted in acute care hospitals in Europe may not transfer directly to a telemetry unit in the United States without considering differences in staffing, patient acuity, and fall prevention protocols.

Students also sometimes confuse systematic reviews with literature reviews. A literature review summarises selected studies on a topic, often without a transparent search protocol or formal quality appraisal. A systematic review follows a predetermined protocol, searches multiple databases exhaustively, appraises each included study, and synthesises results using explicit methods.
