CHAPTER 1
Integrating Research, EBP, and QI Processes
l.,._J
Whether you are a student or a practicing nurse whose goal is to use research as the
foundation of your practice, you will discover that research, evidence-based practice (EBP},
and quality improvement (QI) position our profession at the cutting edge of change and
improvement in patient outcomes. You will also discover the cutting-edge "who;' "what;'
"where;' "when;' "why;' and "how" of research that help you develop a foundation of EBP
knowledge and competencies that will equip you for clinical practice.
Your nursing research adventure will be filled with new and challenging learning experiences that develop your EBP skills. Your critical appraisal skills and clinical decision-making
skills will expand as you develop clinical questions, search the research literature, evaluate
the research evidence found in the literature, and make clinical decisions about applying
the "best available evidence" to your practice. For example, you will be encouraged to ask
important clinical questions, such as,
• What makes a telehealth education intervention more effective with one group of
patients with a diagnosis of congestive heart failure but not another?
• What is the effect of e-learning health literacy modules on self-management of diabetes
in children?
• What research has been conducted to identify barriers to breast cancer screening in
African American women?
• What is the quality of studies conducted about the effectiveness of motivational interviewing in promoting behavioral lifestyle changes for populations at high risk for hypertension?
, Which nurse -delivered smoking cessation interventions are most effective?
This book will help you begin your adventure into EBP by developing an appreciation of
research as the foundation for EBP and QI.
NURSING RESEARCH, EVIDENCE-BASED PRACTICE,
AND QUALITY IMPROVEMENT
Nurses are challenged to stay abreast of new information to provide the highest quality of
patient care (Institute of Medicine [IOM], 201 I). Nurses are challenged to expand their
"comfort zone" by offering creative approaches to old and new health problems and designing new and innovative programs that make a difference in the health status of targeted
populations across the life span. These challenges can best be met by integrating rapidly
expanding research and evidence-based knowledge about biological, behavioral, and environmental influences on health into the care of patients and their families.
It is important to differentiate among research, EBP, and QI. Research is a systematic,
rigorous, critical investigation that aims to answer questions about health-related phenomena. Researchers follow the steps of the scientific process, which are outlined in this chapter
and discussed in detail in each chapter of this text. There are two types of research: quantitative and qualitative. The methods used by nurse researchers are the same methods used
by other disciplines; the difference is that nurses study questions relevant to nursing practice. Published research studies read and evaluated for applicability to practice are used to
inform clinical decisions.
Evidence-based practice is the collection, evaluation, and integration of valid research
evidence, combined with clinical expertise and an understanding of patient and family
values and preferences, to inform clinical decision making (Sackett et al., 2000) . Research
studies are gathered from the literature, and the findings are assessed so evidence-based

evidence. These topics are designed to help you read research articles more effectively and
with greater understanding so you can make evidence-based clinical decisions and contribute to quality and cost-effective patient outcomes.
TYPES OF RESEARCH: QUALITATIVE AND QUANTITATIVE
Research is classified into two major categories: qualitative and quantitative. A researcher
chooses between these categories based on the question being asked. That is, a researcher
may wish to test a cause-and-effect relationship, assess if variables are related, or discover
and understand the meaning of an experience or process. A researcher would choose to
conduct a qualitative research study if the question is about understanding the meaning of a human experience such as grief, hope, or loss. The meaning of an experience is
based on the view that meaning varies, is subjective, and occurs in a context. That is, the
experience of loss as a result of a miscarriage would be different than the experience of
losing a parent.
Qualitative research is generally conducted in natural settings and uses data that are
words or text rather than numeric to describe the experiences being studied. Qualitative
studies are guided by research questions, and data are collected from a small number of
subjects, allowing an in-depth study of a phenomenon. Example:
Hanna et al. (2020)
explored the perceptions that underlie health-related adherence behaviors from the perspective of patients who experienced a heart attack (see Appendix E). Although qualitative
resea rch is systematic in its method, it uses a subjective approach . Data from qualitative
studies help nurses understand experiences or phenomena that affect patients; these data
also assist in generating theories that lead clinicians to develop improved patient care and
stimulate further research. Highlights of the general steps of qualitative studies and the
jo urnal format for a qualitative article are outlined in Table l. l. Chapters 5 to 7 provide
an in -depth view of qualitative research underpinnings, designs, and methods.

CHAPTER 1 Integrating Research, EBP, and QI Processes
Toe primary difference is that qualitative research seeks to interpret meaning and phenomena, whereas quantitative research seeks to test a hypothesis or answer research questions using statistical methods. Remember as you read research articles that, depending on
the research question, a researcher may vary the steps slightly; however, each step should
be addressed systematically.
CRITICAL APPRAISAL SKILLS
To develop expertise in EBP, you will need to be able to critically evaluate all types of
research articles. As you read a research article, you may be struck by the difference
in style or format of a research article versus a clinical article. The terms of a research
art icle are new, and the content is different. You may also be thinking that the research
art icle is hard to read or that it is technical and boring. You may simultaneously wonder,
"How will I possibly learn to appraise all of the steps of a research study, the terminology,
and th e process of EBP? I'm only on Chapter I. This is not so easy; research is as hard as
everyone says:'
Lea rning the research process develops your critical appraisal skills. You will gradually
be able to read a research article and determine whether the conclusions are based on the
study's fi ndi ngs. Once you have obtained this critical appraisal competency, you will be
rea dy to synthesize the findings of multiple studies to use in developing an EBP.

campus Select a research study to read, understand. and critically appraise together. It is always helpful to collaborate on deciding whether the findings are applicable to clinical practice.
STRATEGIES FOR APPRAISINGRESEARCH STUDIES
Critical appraisal of a study objectively and critically evaluates a study's content for its
strengths and weaknesses and overall applicability to practice. It requires some knowledge
of the subject matter and knowledge of how to use critical appraisal criteria. In this text,
you will find:
• Summarized examples of critical appraisal criteria for qualitative studies and an example
of a qualitative critique in Chapter 7
• Summarized critical appraisal criteria and examples of a quantitative critique in
Chapter 18
• An in-depth exploration of the criteria for evaluation required in quantitative research
in Chapters 8 to 18
• Criteria for qualitative research in Chapters 5 to 7
• Principles for qualitative and quantitative research in Chapters 1 to 4
Critical appraisal criteria are the standards, appraisal guides, or questions used to evaluate an article. When analyzing a research article, you must evaluate each step of the research
process and ask questions about whether each step meets the criteria. For instance, the critical appraisal criteria in Chapter 3 ask if "the literature review identifies gaps and inconsistencies in the literature about a subject, concept, or problem;' and if "all of the concepts and
variables are included in the review:' These two questions relate to appraising the research

FIG 1.1 Levels of Evidence. Evidence hierarchy for rating levels of evidence associated with
a study's design. Evidence is assessed at a level according to its source.
Act (ACA) involves considering interventions that are affordable, accessible, available, and
culturally congruent with the targeted community. EBP involves processes and steps, as
does the research process. These steps are presented throughout the text. Chapter 19 provides an overview of EBP steps and strategies.
When using EBP strategies, the first step is to be able to read a study with an understanding of
how each section is linked to the steps of the research process. The following section introduces
you to the research process as presented in published articles. Once you read a study, you must
decide which level of evidence the study provides and how well the study was designed and executed. Fig. 1.1 illustrates a model for determining the levels of evidence associated with a study's
design, ranging from systematic reviews of randomized controlled trials (RCTs) (see Chapters 9
and 10) to expert opinions. The rating system, or evidence hierarchy model, presented here is
just one of many. Many hierarchies for assessing the relative worth ofboth qualitative and quantitative designs are available. Early in the development ofEBP, evidence hierarchies were thought
to be very inflexible, with systematic reviews or meta-analyses at the top and qualitative research
at the bottom. This is no longer the case. There is no guarantee that a Level II RCT with design
flaws will provide stronger evidence than a well-designed Level III cohort study.

review of these guidelines, which are found on a journal's website, will give you an idea of
the format of articles that appear in specific journals.
Remember that even though each step of the research process is discussed at length in this
text, you may find only a short paragraph or a sentence in an article that provides the details
of the step. A publication is a shortened version of the researcher(s) completed work. You will
also find that some researchers devote more space in an article to the results, whereas others
present a longer discussion of the methods and procedures. Decisions about the amount of
material presented for each step of the research process are bound by the following:
• The journal's space limitations
• The journal's author guidelines
• The type or nature of the study
The researcher's decision regarding which component of the study is most important
The following discussion provides a brief overview of each step of the research process
and how it m ay appear in an article. It is important to remember that a quantitative research
article will differ from a qualitative research article. The components of qualitative research
are discussed in Chapters 5 and 6 and are summarized in Chapter 7.
Abstract
An abstract is a short, comprehensive synopsis or summary of a study at the beginning
of an article. An abstract quickly focu ses the reader on the main points of a study. A
well -presented abstract is accurate, self-contained, concise, specific, nonevaluative, coherent, and readable. Abstracts vary in word length. The length and format of an abstract
are dictated by the journal's style. Both quantitative and qualitative research studies have
abstracts that provide a succinct overview of the study. Examples of abstracts can be found
in each of the articles in the appendices.
An abstract is a concise shon overvi ew that provides a reference to the research purpose. research questions,
hypotheses, methodology, resu lts, and implications for practice or future research.
Introduction/Study Purpose
Early in a research article, in a section that may or may not be labeled "Introduction;' or
"Purpose;' the researcher presents a background picture of the area researched and its significance to practice (see Chapter 2) . The study's purpose may or may not be labeled (see
Chapters 2 and 3), or it may be referred to as the study's aim or objective. The studies in
Appendices A to E present specific purposes for each study in untitled sections that appear
in the beginning of each article and in the article's abstract.
Literature Review and Theoretical Framework
Authors of studies present the literature review and theoretical framework in different ways.
Many research articles merge the "Literature Review" and the "Theoretical Framework:'
This section includes the main concepts investigated and may be called "Review of the Literature:• "Literature Review;• "Theoretical Framework;' "Related Literature;• "Background;'
"Conceptual Framework;' or it may not be labeled at all (see Chapters 2 and 3). One style is
not better than another; the studies in the appendices contain all of the critical elements but
present the elements differently.

understand how to link the levels of evidence with quantitative designs. A study may not
indicate the specific design used; however, all studies inform the reader of the methodology
used, which can help you decide the type of design the authors used to guide the study.
Sampling
The population from which the sample was drawn is discussed in the section "Methods"
or "Methodology" under the subheadings of "Subjects" or "Sample" (see Chapter 12).
Researchers should identify for you the population from which the sample was chosen, the
inclusion criteria, the number of subjects who participated in the study, and a description of
subjects who dropped out of the study. The authors of the studies in the appendices discuss
their samples in enough detail so the reader is clear about who the subjects are and how
they were selected.
Reliability and Validity
A discussion of the instruments used to study the variables is usually included in a
"Methods" section under the subheading of"Instruments" or "Measures" (see Chapter 14).
Usually a discussion of each instrument (or scale) used in the study along with its reliability and validity is included (see Chapter 15). The studies in the appendices discuss
each of the measures used in the "Methods" section under the subheading "Measures" or
"Instruments;• "tools and data collection;• and "outcome measures and data collection:' Toe
reliability and validity of each measure is not always presented, but references with this
information are usually cited.
Procedures and Data Collection Methods
The data collection procedures, or the individual steps taken to gather measurable data
(usually with instruments or scales), are generally found in the "Procedures" or "Data Collection" section (see Chapter 14). Notice that the researchers in the studies in the Appendices provided information that the studies were approved by an institutional review board
(see Chapter 13), thereby ensuring that each study met ethical standards.
Data Analysis/Results
Data analysis procedures (i.e., the statistical tests used and the results of descriptive and/
or inferential tests applied in quantitative studies) are presented in the "Results" or "Findings" section (see Chapters 16 and 17). Although qualitative studies do not use statistical
tests, the procedures for analyzing the themes, concepts, and/or observational or print data
are usually described in the "Method" or "Data Collection" section and reported in the
"Results;' "Findings;• or "Data Analysis" section (see Appendix E and Chapters 5 and 6).
Discussion
The last section of a research study is the "Discussion" section (see Chapter 17). In this section, the researchers tie together all of the study's components and give a wholistic picture
of the study. The researchers return to the literature reviewed and discuss how their study is
similar to or different from other studies. Researchers may report the results and discussion
in one section but usually report their results in separate "Results" and "Discussion" sections (see Appendices A to E) . One particular format is no better than another. Journal and
space limitations determine how these sections will be handled. Any new or unexpected
findings are usually described in the "Discussion" section.

terms systematic review and integrative review interchangeably. Both a meta-synthesis
and meta-summary are the synthesis of a number of qualitative research studies on a
focused topic using specific qualitative methodology (Kastner et al., 2016; Sandelowski
& Barrosos, 2007).
The components of review articles will be discussed in greater detail in Chapters 6,
11, and 20. These articles take a number of studies related to a clinical question and,
using a specific set of criteria and methods, evaluate the studies as a whole. Although
they may vary somewhat in approach, these reviews all help better inform and develop
EBP. The meta-analysis in Appendix E is an example of a systematic review that is a
meta-analysis.
CLINICAL GUIDELINES
Clinical guidelines are systematically developed statements or recommendations that
serve as a guide for practitioners. Two types of clinical guidelines will be discussed throughout this text: consensus, or expert-developed guidelines, and evidence-based guidelines.
Consensus guid elines, or expert-developed guidelines, are developed by an agreement
of experts in the field. Evidence-based guidelines are those developed using published
research findings. Guidelines are developed to assist in bridging practice and research and
are developed by professional organizations, government agencies, institutions, or convened expert panels. Clinical guidelines provide clinicians with an algorithm for clinical
management or decision making for specific diseases (e.g., breast cancer) or treatments
(e.g., pain management). Not all clinical guidelines are well developed and, like research,
must be assessed before implementation. Though they are systematically developed and
make explicit recommendations for practice, clinical guidelines may be formatted differently. Guidelines for practice are becoming more important as third-party and government
payers are requiring practices to be based on evidence. Guidelines should present the scope
and purpose of the practice, detail who the development group included, demonstrate scientific rigor, be clear in its presentation, demonstrate clinical applicability, and demonstrate
editorial independence (see Chapter 11 ).
QUALITY IMPROVEMENT
As a health care provider, you are responsible for continuously improving the quality and
safety of health care for your patients and their families through systematic redesign of
health care systems in which you work. The !OM (201 I) defined quality health care as care
that is safe, effective, patient-centered, timely, efficient, and equitable. Therefore the goal
of QI is to bring about measurable changes across these six domains by applying specific
methodologies within a care setting. Although several QI methods exist, the core steps for
improvement commonly include the following:
• Conducting an assessment
• Setting specific goals for improvement
• Identifying ideas for changing current practice
• Deciding how improvements in care will be measured
Rapidly testing practice changes
Measuring improvements in care
Adopting the practice change as a new standard of care

how these sections link with one another to support the researcher's conclusions and
recommendations.
