Conduct a literature search on your selected topic. Conduct the search using an external source [use the library databases] vs. internal source [use the hospital's Policy & Procedure Policies]. Select appropriate articles for critique from articles with research conducted in the USA and non-USA countries (the global perspective).
Include at least four (4) different articles [1 systematic review, 1 quantitative, 1 literature review, and 1 Quality Improvement report]. Use only current literature published within the past 5 years (2019 – 2024) with evidence to answer the PICO question.
PICOT question: In adult patients, how does ambulation within the first 12 hours after an operation, compare to delaying ambulation beyond 12 hours post-op, affect patient outcomes within 30 days after surgery?
The purpose of EBP Part 2 is to begin (rather to continue) your search for research evidence to answer your PICO question from EBP Part 1. To find the best evidence available, post your selected articles early to ensure inclusion/exclusion criteria 1) no duplicated articles; 2) each Team member must submit (4) different articles – 1 systematic review, 1 quantitative, 1 literature review, and 1 QI report; 3) current literature published in the past 5 years with evidence to answer the PICO; and 4) out of the 4 quantitative research articles, at least one study was conducted in the United States and at least one study was conducted internationally.
Appraise the level & quality of each article selected using Research Evidence Appraisal Tool and Hierarchy of Evidence Guide. (documents attached)
Follow the prompts; answer the questions; complete one sheet for each of the four (4) different articles.

Individual Evidence Summary Tool (DOCUMENT ATTACHED) ***available alternative summary table*** The alternative table is a word doc with the same headings as the Johns Hopkins Table.
Each person will provide the information for four (4) articles they selected.
The table headers indicate the important elements of each article that will contribute to the synthesis. The data on each cell should be complete enough that the other team members are able to gather all relevant information related to the evidence without having to go back to each article again.

Article Appraisal Workflow Is this study:
☐ QuaNtitative (collection, analysis, and reporting of numerical data) Numerical data (how many, how much, or how often) are used to formulate facts, uncover patterns, and generalize to a larger population; provides observed effects of a program, problem, or condition. Common methods are polls, surveys, observations, and reviews of records or documents. Data are analyzed using statistical tests. Go to Section I for QuaNtitative leveling
☐ QuaLitative (collection, analysis, and reporting of narrative data) Rich narrative data to gain a deep understanding of phenomena, meanings, perceptions, concepts, and experiences from those experiencing it. Sample sizes are relatively small and determined by the point of redundancy when no new information is gleaned, and key themes are reiterated (data saturation). Data are analyzed using thematic analysis. Often a starting point for studies when little research exists; may use results to design empirical studies. Common methods are focus groups, individual interviews (unstructured or semi-structured), and participation/observations. Go to Section II for QuaLitative leveling
☐ Mixed methods (results reported both numerically and narratively) A study design (a single study or series of studies) that uses rigorous procedures in collecting and analyzing both quaNtitative and quaLitative data. Note: QuaNtitative survey designs with open-ended questions do not meet criteria for mixed methods research because those questions are not approached using strict quaLitative methods. Mixed methods studies provide a better understanding of research problems than using either a quaNtitative or quaLitative approach alone. Go to Section III for Mixed Methods leveling
Does this evidence answer the EBP question? ☐ Yes Continue appraisal ☐ No STOP, do not continue evidence appraisal

Level III studies lack manipulation of an independent variable; can be descriptive, comparative, or correlational; and often use secondary data

A/B High/Good Quality: The report discusses efforts to enhance or evaluate the quality of the data and the overall inquiry in sufficient detail; it describes the specific techniques used to enhance the quality of the inquiry.
Evidence of at least half or all the following is found in the report:
• Transparency: Describes how information was documented to justify decisions, how data were reviewed by others, and how themes and categories were formulated.
• Diligence: Reads and rereads data to check interpretations; seeks opportunity to find multiple sources to corroborate evidence.
• Verification: The process of checking, confirming, and ensuring methodologic coherence. • Self-reflection and self-scrutiny: Being continuously aware of how a researcher’s experiences, background, or

Section III: Mixed Methods Appraisal You will need to appraise both parts of the study independently before appraising the study as a whole. Evaluate the quaNtitative part of the study using Section I. Evaluate the qualitative part of the studying using Section II, then return here to complete appraisal.

Level Quality
QuaNtitative Portion
QuaLitative Portion
The level of mixed methods evidence is based on the sequence of data collection. Quantitative data collection followed by quaLitative (explanatory design) is based on the level of the quaNtitative portion. All other designs (exploratory, convergent, or multiphasic) are Level III evidence.
Explanatory sequential designs collected quantitative data first, followed by qualitative. Exploratory sequential designs collect qualitative data first, followed by quantitative. Convergent parallel designs collect quantitative and qualitative data at the same time. Multiphasic designs collect qualitative and quantitative data over more than one phase.

After determining the level of evidence, determine the quality of evidence using the considerations below:
Was the mixed-methods research design relevant to address both quaNtitative and quaLitative research questions (or objectives)? ☐ Yes ☐ No Was the research design relevant to address the quaNtitative and the quaLitative aspects of the mixed-methods question (or objective)? ☐ Yes ☐ No
Circle the appropriate quality rating below:
A High quality: Contains high-quality quaNtitative and quaLitative study components; highly relevant study design; relevant integration of data or results; and careful consideration of the limitations of the chosen approach.
B Good quality: Contains good-quality quaNtitative and quaLitative study components; relevant study design; moderately relevant integration of data or results; and some discussion of limitations of integration.
C Low quality: Contains low quality quaNtitative and quaLitative study components; study design not relevant to research questions or objectives; poorly integrated data or results; and no consideration of limits of integration.
