Before ___ can be conducted, a number of issues must be explored. All subjects must have provided informed consent. Their responses must remain anonymous and confidential.

scientific method

The foundation of research The most reliable and objective means of acquiring and conducting research and gaining knowledge. A step-by-step process to ensure that findings from a study are valid, reliable, and generalizable to a similar group of subjects. The goal is to apply the knowledge gained from a study to a broader group of patients.

evaluate

After applying evidence in your practice, your next step is to ___ the outcome. Events or results that you do not expect may occur. Never implement a practice change without ____ its effects.

research study.

After completing a thorough review and critique of the scientific literature, you might not have enough strong evidence to make a practice change. Instead you may find a gap in knowledge that makes your PICOT question go unanswered. When this happens, the best way to answer your PICOT question is to conduct a_____

After critiquing all articles for a PICOT question: Do the articles offer evidence to explain or answer my PICOT question? Do the articles show support for the ___ and ___ of the evidence? Can I use the evidence in ___?

EBP:, Research:,QI:

Although EBP, research, and QI are closely related, they are separate processes. The relationship among research, EBP, and QI is overlapping and reinforcing. ____ Use of information from research and other sources to determine safe and effective nursing care with the goal of improving patient care and outcomes _____Systematic inquiry answers questions, solves problems, and contributes to the generalizable knowledge base of nursing; may or may not improve patient care ___Improves local work processes to improve patient outcomes and health system efficiency; results usually not generalizable

Manuscript narrative

Element of an evidence based article, _____. The "middle section" or narrative of an article differs according to the type of evidence-based article it is. A clinical article describes a clinical topic, which often includes a description of the patient population, the nature of a certain disease or health alteration, how patients are affected, and the appropriate nursing therapies.

Methods or design:

Part of the manuscript narrative portion of elements of evidence based article, ____ Explains how a research study was organized and conducted to answer the research question or test the hypothesis. This section explains the type of study that was conducted (e.g., RCT, case control study, or qualitative study) and the number of people who participated in the study.

Purpose statement:

In a research article, the author details the results of the study and explains whether a hypothesis is supported or how a research question is answered. This section includes a statistical analysis if it is a quantitative research study. A qualitative study summarizes the descriptive themes and ideas that arise from the researcher's analysis of data.

Clinical implications:

Part of the manuscript narrative portion of elements of evidence based article, _____ A research article includes a section that explains if the findings from the study have clinical implications. The researcher explains how to apply findings in a practice setting for the type of subjects studied.

nonexperimental

Quantitative method, Because learning to understand how patients experience health problems cannot always be addressed through an RCT, ____ descriptive studies are often used in nursing research. ____ descriptive studies describe, explain, or predict phenomena. Examples of ____ descriptive studies include case control studies and correlational studies. A case control study is one in which researchers study one group of subjects with a certain condition (such as asthma) at the same time as another group of subjects who do not have the condition. A case control study determines if there is an association between one or more predictor variables and the condition. Correlational studies describe the relationship between two variables (such as the age of the adolescents and if the adolescents smoke). The researcher determines if the two variables are correlated or associated with one another and to what extent.

Experimental research:

Quantitative method, One example of _____ is the randomized controlled trial. An RCT is a true experimental study that tightly controls conditions to eliminate bias with the goal of generalizing the results of the study to similar groups of subjects.

Surveys

Quantitative method, ___ obtain information regarding the frequency, distribution, and interrelation of variables among subjects in the study.

Evaluation

Quantitative method, ____ research is a form of quantitative research that determines how well a program, practice, procedure, or policy is working.

health care setting

hierarchy

The ___ of available evidence offers a guide to the types of literature or information that offer the best scientific evidence. This diagram of the ____ of evidence shows that stronger evidence is farther up the triangle. For instance, a well-designed randomized controlled trial (RCT) carries more weight than even the opinions of experts.

National Guidelines Clearinghouse (NGC)

The ____ is a database supported by the AHRQ. It contains clinical guidelines, which are systematically developed statements about a plan of care for a specific set of clinical circumstances involving a specific patient population.

scientific journals

The best information is evidence that comes from well-designed, systematically conducted research studies, mostly found in _____. It is important to rely more on research evidence rather than solely on evidence that is not research based.

PICOT

The questions you ask eventually will lead you to the evidence for an answer. When you go to the scientific literature, you don't want to read 100 articles to find the handful that are most helpful—you want to read the best four to six articles that specifically address your question. Using the ____ format can help. The more focused your question is, the easier it becomes to search for evidence in the scientific literature. Note that a well-designed ____ question does not have to follow the sequence of P, I, C, O, and T. In addition, intervention (I), comparison (C), and time (T) are not appropriate to be used in every question. The aim is to ask a question that contains as many of the PICOT elements as possible.

clinical experts

The use of ____ is at the bottom of the evidence pyramid, but do not consider ___ to be a poor source of evidence. ___ use evidence frequently as they build their own practice, and they are rich sources of information for clinical problems.

textbook, Articles, quality improvement, risk management

There are many sources of evidence. The challenge is to obtain the very best, most relevant, current, and accurate information at the right time, when you need it for patient care. A good ____ incorporates evidence into the information, practice guidelines, and procedures it includes. ___ from nursing and health care literature are available on almost any topic involving nursing practice in either journals or on the Internet. Another source of evidence comes from ____ and ____ data; international, national, and local standards of care; infection control data; benchmarking, retrospective, or concurrent chart reviews; and clinicians' expertise.

pilot study

When evidence is not strong enough to apply in practice, your next option is to conduct a ___ to investigate your PICOT question. A ___ is a small-scale research study or one that includes a quality or performance improvement project.

QI data

When implementing an EBP project, it is important to first review evidence from appropriate research and ____data. This information helps you better understand the extent of a problem in practice and within your organization. ___ data inform you about how processes work within an organization and thus offer information about how to make EBP changes. EBP and QI sometimes provide opportunities for research.

medical librarian

When using scientific literature for evidence, seek the assistance of a ____ who knows the various online databases that are available to you.

clinical problem

When you face a _____, always ask yourself where you can find the best evidence to help you find the best solution in caring for patients. Even when you use the best evidence available, application and outcomes will differ on the basis of your patient's values, preferences, concerns, and/or expectations. As a nurse you develop critical thinking skills to determine whether evidence is relevant and appropriate to your patients and to a clinical situation.

RCTs, Single RCT

___ are the most precise forms of experimental study and therefore are the gold standard for research. 2nd from the top of pyramid, A ___ is not as conclusive as a review of several ____ on the same question. However, a ___ that tests the intervention included in your question yields very useful evidence.

Qualitative

___ nursing research is the study of phenomena that are difficult to quantify or categorize, such as patients' perceptions of illness or quality of life.
