12. To avoid selection bias, it would be best for the researcher to a.

maintain constancy.

b.

assure homogeneity.

c.

include randomization of groups.

d.

limit maturation.

ANS: C

Randomization of groups will avoid selection bias which can result if precautions are not taken when subjects are chosen.

Constancy is referred to as sameness in methods and procedures of data collection. Homogeneity is similarity of conditions during the study. Maturation can occur in studies that test an intervention or variable over time and refer to the developmental, biological, physiological, or psychological processes within an individual as a function of time and are external to a study’s events differences between the two testing periods rather than the experimental treatment.

13. A pilot study can be best described as a.

making sure all of the conditions in the study are the same.

b.

a small study conducted as a prelude to a larger scale study.

c.

changes in the measurement of a variable that may account for changes in the obtained measurement.

d.

degree of control or uniformity of the study methods.

ANS: B

A pilot study is a small study conducted as a prelude to a larger scale study. Homogeneity is assurance of similarity of conditions in the study. Instrumentation refers to changes in the measurement of a variable that may account for changes in the obtained measurement. Fidelity refers to the degree of control or uniformity of the study methods.

14. Which of the following is not a component of intervention fidelity? a.

Enactment

b.

Training

c.

Delivery

d.

Internal validity

ANS: D

Elements of intervention fidelity include: design, training, delivery, receipt, and enactment. Internal validity assesses if the change in the dependent variable or study outcome was related to the independent variable.

TRUE/FALSE

1. The lack of manipulation of the independent variable of a study results in a weaker study.

ANS: F

The lack of manipulation of the independent variable does not mean a weaker study.

2. Threats to internal validity are assessed in intervention studies and are not considered in quantitative studies.

ANS: F

Threats to internal validity are mainly assessed in intervention studies but can also compromise outcomes of all quantitative studies.

3. When assessing the evidence, more than one threat can be found in a study design.

ANS: T

Depending on the study design, more than one threat can be found in a study.

4. Finding a threat to internal validity in a study invalidates the study’s results.

ANS: F

Finding a threat to internal validity in a study does not invalidate a study’s results but it should be acknowledged in the study’s “Results” or “Discussion” or “Limitations” section.

5

5. Problems of internal validity are generally easier to control compared to problems with external validity.

ANS: T

Problems of internal validity are generally considered easier to control, however external validity is usually more difficult to control because it means that the researcher is assuming that other populations are similar to the one being tested. As more controls are designed into a study, internal validity improves, but generalizability is likely to decline.

6. Evaluation is the synthesis of the overall strengths, quality, and consistency of the evidence provided by the studies retrieved.

ANS: T

Evaluation occurs by synthesizing the overall strengths, quality, and consistency of the evidence provided by the studies retrieved.

7. External validity is the degree to which findings can be generalized to other populations or environments.

ANS: T

External validity is the degree to which findings can be generalized to other populations or environments.

8. Internal validity refers to the consistency among and between the groups being studied.

ANS: F

Internal validity is the degree to which one can infer that the intervention, rather than another condition or variable, resulted in the outcome or observed effects.

assignment is not readily known by anyone before the subject is assigned to a group? a.

Concealment

b.

Blind

c.

Control

d.

Intent-to-treat analysis

ANS: A

The process of protecting the randomization process to make sure the group assignment is not readily known by anyone before the subject is assigned to a group is known as concealment. Blind, blinded, or blinding is the process of making unknown what the subject is receiving in the study. Control is the arm of a randomized trial in which participants receive the standard treatment or possibly a placebo, and intent-to-treat analysis is the statistical process of analyzing data according to randomized groups exactly as it exists upon randomization.

conditions. a.

Open label

b.

Effectiveness trial

c.

Feasibility study

d.

Efficacy trial

ANS: D

An efficacy trial is a trial that is statistically powered and designed to test an intervention under well-controlled conditions. An effectiveness trial is a trial that is designed to test an intervention under “real-world” conditions. A feasibility study is designed to examine if the planned intervention is worth testing in a larger full-scale. It is also used as a trial to identify modifications needed to the intervention, methods, or design. Open label is a type of trial in which both the researcher and the study subjects know what they are receiving.

3. Which of the following statements about intervention studies does the nurse researcher identify as not being true? a.

Intervention studies are often called randomized controlled (clinical) trials.

b.

Intervention studies are the weakest design type for an individual study.

c.

Intervention studies are located at level I on the evidence hierarchy.

d.

Intervention studies are the most appropriate type of design to test prognosis.

ANS: A

Rationale intervention studies are often called randomized controlled (clinical) trials. They are the strongest design type for individual studies and are located at level II on the evidence hierarchy. RCTs are the most appropriate type of design to answer questions about the effectiveness and efficacy of interventions focused on testing cause and effect relationships.

4. When describing quasi-experimental design to a research team, which of the following statements should the team leader include? a.

Quasi-experimental designs are a type of randomized controlled trial.

6. A clinical leadership team is planning to test an intervention they developed. Which of the following is the most appropriate

research design for the group to use? a.

Quasi-experimental design

b.

Randomized controlled trials

c.

After-only design

d.

Pilot study

ANS: B

Randomized controlled trials, commonly called intervention studies use an experimental design and are the gold standard for testing an intervention. Quasi-experimental intervention studies test for change through manipulation of the independent variable; however they lack one of the three key properties of an experimental design, typically randomization, or presence of a control group. The after-only design is less frequently used and is a weaker design composed of two randomly assigned groups and unlike the classic experimental design, neither group is pretested. A pilot study is defined as a small sample study conducted as a prelude to a larger sale study to establish if sufficient scientific evidence exists to justify subsequent more extensive research while providing more experience for the research team.

7. When designing an intervention study using an experimental design, which of the following is not an essential feature to be

included in the design? a.

Control

b.

intervention? a.

Crossover design

b.

Solomon four-group design

c.

Randomized controlled trial

d.

After-only design

ANS: D

The after-only design is used less frequently and is a weaker design composed of two randomly assigned groups, but unlike the classic experimental design, neither group is pretested. This design is useful when pretesting of outcomes is not possible such as when testing the effectiveness of a post-cesarean section delivery pain management intervention. A crossover design is considered a repeated measures design in which subjects serve as their own controls. Solomon four-group design consists of two experimental and two control groups. Two groups are identical to those used in the classic experimental design plus two additional groups, an experimental after-group and a control after-group. Solomon four-group design results in two groups that receive only a posttest rather than a pre- and posttest. This design provides an opportunity to minimize testing bias that may have occurred because of exposure to the pretest. A randomized control trial requires control, randomization, and manipulation of variables.

9. Which of the following designs would be most effective for a research team to use when determining which key ingredients in a

bundled intervention make a difference over time using a factorial design to pull apart each component and test then in varying combinations? a.

Pragmatic trial design

b.

SMART design

c.

Intervention study

d.

MOST design

ANS: D

Multiphase optimization strategy (MOST) is a proposed alternative approach to RCTs. MOST uses a factorial design to pull apart each component and test them in varying combinations to extract which key ingredients in a bundled intervention make a difference over time. Sequential multiple assignment randomized trial (SMART) allows tailored components based on patient responses taking into account individual patient responses, adherence to treatment and personal preferences to be used in tailoring 3

the intervention. Guidelines for these individualized sequences of treatment are known as dynamic treatment regimens (DTRs).

Pragmatic trial designs evaluate the effectiveness of an intervention previously tested for efficacy in traditional experimental designs. The focus is on whether the intervention is doable and effective in the real-world clinical setting compared to other accepted clinical practice treatments. An intervention study is also known as a therapy study or randomized controlled trial.

10. Which of the following statements about quasi-experimental design is not true? a.

Quasi-experimental designs lack all of the three key properties of an experimental design.

c.

Quasi-experimental intervention studies test for change through manipulation of the independent variable.

d.

Threats to internal validity such as selection effect, testing, and mortality are common with quasi-experimental design.

ANS: A

Quasi-experimental designs lack one of the three key properties of an experimental design usually randomization or presence of a control group. Threats to internal validity such as selection effect, testing, and mortality are common with quasi-experimental design. Quasi-experimental interventions test for change through manipulation of the independent variable. The basic problem with quasi-experimental designs is weakened confidence in making causal assertions that the results occurred because of the intervention.

d.

Power calculation

ANS: B

The following should be assessed when thinking about critically appraising intervention fidelity; use of an Intervention Manual, were all research personnel trained on the careful execution of the intervention, the consistency with which the researchers executed the intervention, and measurement of adherence to the protocol. Blinding, also called masking, is the process of concealing from the researchers, recruiters, interventionists, subjects, and/or data collectors what treatment the subjects are receiving in the study. Power analysis is calculated to reduce the probability of making a type II error. A power calculation is used to determine the number of participants needed to detect a small, medium, or large treatment effect as well as if there is a difference between the intervention and control condition at a predetermined level of significance.

13. A CONSORT Diagram is best defined as an analysis of a.

content validity.

b.

construct validity.

c.

treatment fidelity.

d.

If the number of participants originally enrolled in the trial complete the study.

ANS: D

A CONSORT Diagram evaluates whether the number of participants originally enrolled in the trial completed the study. Content validity is the most common type of validity seen resented in research articles. Construct validity is more often referred to in citations from original psychometric studies and treatment fidelity refers to processes used to make sure that the research intervention, and all related activities, were delivered exactly as planned to ensure that the treatment effect found or not found was due to the intervention, and not to alternations in execution of the study.

think about the relevance of the findings to patients cared for.

c.

understand statistics.

d.

determine whether results are of sufficient quality and consistency to consider applying them to practice.

ANS: C

A meta-analysis is a complex and time consuming undertaking. The role of the clinician, educator, or administrator does not require an in-depth understanding of statistics. It is the role of the clinician, educator, or administrator to understand and interpret the findings of a meta-analysis to determine whether the results are of sufficient quality and consistency to consider applying them to practice and finally to think about their relevance for patient, student or staff resources, and setting.

8. An EBP team plans to perform a meta-analysis guided by their clinical question. The first step the team should follow to perform

the meta-analysis is a.

search only randomized controlled studies.

b.

search by expert authors.

b.

the results of the meta-analysis are uncertain and easily could change if other studies were included.

c.

publication bias exists.

d.

studies with non-positive findings have not been published.

ANS: A

If the fail-safe number is large, many studies would be needed to overturn the treatment effects results and one would be more confident about the reported findings. If the fail-safe number is small, the results of the meta-analysis are uncertain and easily could change if other studies were included.

Attrition bias assesses how incomplete data were managed and reporting bias assesses whether all intended outcomes were reported.

11. A test of heterogeneity is completed during a meta-analysis and finds the null hypothesis is supported at the p < .05 level. The EBP

team interprets this as meaning. a.

There are multiple outliers.

b.

The studies are too diverse or heterogeneous to be pooled legitimately and analyzed statistically as pooled sample in a meta-analysis and might conclude as non-quantitative systematic review.

c.

The studies are considered similar and appropriate for a combined statistical analysis.

3

d.

The effect size is too small.

ANS: C

When the null hypothesis is supported at the p < .05 level, the studies are considered similar and appropriate for a combined statistical analysis. If the null hypothesis is rejected, the studies are too diverse or heterogeneous to be pooled legitimately and analyzed statistically as pooled sample in a meta-analysis and might conclude as non-quantitative systematic review. Sensitivity analysis can be used to examine the effect of those studies that are outliers.

12. Which of the following statements about integrative review is incorrect? Integrative reviews a.

include critical appraisal of the literature in a specific area.

b.

includes a statistical analysis.

qualitative research design incorporating the case study approach to review the program. The manager should a.

not follow the case study approach as more than one person will be studied.

b.

realize that case studies apply only to the specific geographic location where the study takes place.

c.

pose questions to begin the case study data collection and grow the questions as data are collected.

d.

review anthropology as it is the basis of the case study approach.

ANS: C

A single case may be an individual, a family, a community, or an organization. Case studies emphasize a holistic approach to the research that may lead to the identification of patterns consistent across a set of cases that contribute to a more global understanding of a particular problem. To begin a case study, researchers pose questions understanding that the initial questions are never all inclusive. The researcher should use an iterative process of “growing questions” in the field. As data are collected, other questions emerge and serve to guide the researcher’s quest to untangle the complexities the case. Case study research is rooted in sociology and focuses on describing elements of an individual case including the commonalities and the peculiarities.

c.

A highly specific test means that there are few false positive results.

d.

The gold standard test is not a component used for review of specificity.

ANS: C

A highly specific test means that there are few false positive results. Sensitivity is the test’s ability to correctly designate a subject with the disease as positive. Specificity is the test’s ability to correctly designate a subject without the disease as negative. Tests with low specificity have the disadvantage that many subjects without the disease will screen positive and potentially receive unnecessary follow-up diagnostic or therapeutic procedures. The gold standard is the single test that is considered the current preferred method of diagnosing a particular disease. It should be used by the researcher to populate the table to compare testing information of new test or nursing interventions.

9. When reading a meta-analysis study, the researcher reviews the statistical analysis section of the report. Which of the following

d.

Studies reviewed reported together as a whole through measures of central tendency

ANS: A

The relative risk, commonly called the odds ratio is the statistic of choice for use in meta-analysis. Meta-analysis often reports on continuous data, typically the mean difference in outcomes. Blobograms, a pictorial representation to display data, is the usual manner of displaying data for a met-analysis. The findings from each individual study are presented.

10. A researcher is reviewing a study that investigated the development of asthma in children who were diagnosed with respiratory

syncytial virus in the first 3 months of life. The odds ratio was calculated to be 1. What does this mean? a.

The null hypothesis was accepted.

b.

The null hypothesis was rejected.

c.

Respiratory syncytial virus did not affect odds of asthma.

d.

Respiratory syncytial virus was associated with higher odds of asthma development.

ANS: C

Prognosis studies often use longitudinal cohort design. At the conclusion of a longitudinal study, investigators statistically analyze data to determine which factors are strongly associated with study outcomes usually through a technique called multivariate regression analysis or simply multiple regression. If the odds ratio is = 1 or the confidence interval = 1, exposure does not affect odds of outcome. If the odds ratio is greater than 1 and the confidence interval does not include 1, exposure is associated with higher odds of outcome.

13. When a research team develops conclusions from their study and report that the findings are significant when they actually are not,

the situation is referred to as a.

type I error.

b.

type II error.

c.

null value.

d.

negative predictive value.

ANS: A

When a researcher states that the findings are significant when they are not, the situation is referred as type I error. This is serious because evidence used to change practice can lead to wrong conclusions and perhaps inappropriate changes in practice. Type II error occurs when an instrument, or test, incorrectly predicts that a phenomenon of interest will not occur. Null value is the value of no effect; in experimental study design it often means there is no difference in the outcomes between the experimental and control group. Negative predictive value expresses the proportion of those with negative test results who truly do not have disease.

14. To reduce the probability of committing a type II error, researchers often conduct which type of analysis? a.

P-value

b.

Receiver operating characteristic (ROC) curve

c.

Power analysis

d.

Standard deviation

ANS: C

A power analysis is a method of determining statistical power which is the probability of correctly rejecting a null hypothesis. A probability value, p-value, is a numeric value that helps determine whether the null hypothesis should be rejected or accepted. A ROC curve is a plot of the true positive rate against the false positive rate for different possible cut points of a diagnostic test.

Standard deviation is a numeric measure of the variation or spread of values in a set of data.

15. When reading study results, which of the following provides information on the clinical meaningfulness of the results? a.

Confidence interval

b.

Chapter 15: Patient-Centered Evidence-Based Practices LoBiondo-wood: Evidence-Based Practice for Nursing and Health Care Quality Improvement, 1st Edition

MULTIPLE CHOICE

1. A nurse practitioner is caring for a 28 year patient recently diagnosed with stage 4 ovarian cancer. A barrier to shared

decision-making would be for the nurse practitioner to a.

tell the patient which treatment option he or she would choose.

b.

ensure the patient understands their treatment options.

c.

encourage the patient to determine their own preferences.

d.

suggest the patient examine her beliefs.

ANS: A

Patients need to fully understand their treatment options and evaluate their own preferences and beliefs to make an informed decision and truly engage in their health decision-making. It is not appropriate to tell patients what to do.

2. Which of the following is not a component of a shared decision-making aid? a.

Incorporation of counseling

b.

Integration of clinical judgment

c.

Inform the patient of their values

d.

Inclusion of risks

ANS: C

Shared decision-making aids are defined as evidence-based documents or tools that portray health care options; give information about risks, benefits, and outcomes for the options; assist the patient to clarify their values; and incorporate clinical judgment and counseling.

3. Which statement by a colleague regarding decision-making aids should the nurse practitioner question? a.

There is no proof of shared decision-making aids efficacy.

b.

Most clinicians use decision-making tools.

c.

Roughly 50 evidence-based decision aids are currently available on the Internet.

d.

There is lack of access to shared decision-making aids.

ANS: A

There is proof of shared decision-making efficacy, however few clinicians and patients utilize existing decision-making tools such as patient decision aids. Even though over 500 evidence-based decision aids are currently available on the Internet, lack of access to these resources is a common complaint by those seeking to use them because they are scattered across dozes of websites and are not well advertised.

4. A new nurse practitioner plans to include patient activation as a major component of their practice. The nurse practitioner

understands that patient activation a.

can be defined as the knowledge the nurse practitioner has to motivate the patient.

b.

is a static state.

c.

includes patient progress and regress between levels of activation at various points in their life.

d.

involves directing the patient where they need to go from the point you meet them forward.

ANS: C

To truly implement patient-centered evidence-based practices, the provider must meet the patient where they are at tailoring strategies that assess their strengths and challenges. Patient activation is defined as the knowledge, confidence, and skills that a patient possesses and is willing to use to make decisions about their health. Patient activation is a dynamic state meaning that a patient can progress and regress between levels of activation at various points in their life.

5. A nurse practitioner is reading a report which includes results of a Patient Activation Measure (PAM) for a patient who has

identified a goal to lower his cholesterol levels. When working with the patient who scored a 4 on the PAM, the nurse 1

practitioner should a.

be prepared to work with someone who has limited problem solving agility.

b.

avoid stressful situations as this patient is more likely to become overwhelmed.

c.

engage the patient in conversation regarding information to enhance their ability to advocate for their own health.

d.

expect to encounter an individual who is more passive about their health.

ANS: C

Higher activated individuals (PAM), levels 3 and 4, are more likely to seek out and use information to be advocates of their own health. They are more likely to participate in wellness activities like regular exercise, maintain a healthy diet, and adhere to medical regimens because they consider themselves partners in their own health promotion. Individuals with lower ranking PAM scores (levels 1 and 2) are more likely to have a low confidence in their ability to self-manage and take a more passive approach to their health. PAM level 1 and 2 patients are less likely to embrace patient support resources, even when offered, and are more likely to be overwhelmed with stressful situations due to limited problem solving agility.

2

6. A nurse practitioner is working with a patient who scored a level 2 on PAM and has been identified as having low health

numeracy with normal health literacy. To enhance this patient’s understanding of correct insulin doses to maintain consistent blood sugars, it would be most effective for the nurse practitioner to a.

provide teaching in written text.

b.

use infographics to break down numbers and display them as pictures.

c.

incorporate graphs into patient teaching.

d.

merge patient and ideal blood glucose recordings into a table for the patient to use.

ANS: B

Infographics that break down numbers and display them as pictures is one of the options to use when working with patients who have low health numeracy. Health literacy is defined as an individual’s ability to access, interpret, and understand qualitative data (no use of numbers) about their health. Health numeracy is an individual’s ability to access, interpret, and understand quantitative data (using numbers) about their health. Graphs and tables would most likely not assist this patient.

7. A nurse practitioner is advocating use of patient portals in the practice where he is employed. The nurse practitioner should focus

on the fact that patient portals have been designed to primarily a.

decrease the amount of time spent charting by staff.

b.

keep information confidential.

c.

facilitate patient flow in the practice.

d.

promote patient engagement and self-care.

ANS: D

Patient portals are web-based platforms which compile various resources for patient engagement, such as decision-making aids, educational materials and communication applications which are typically connected to the electronic health record. They are designed to promote patient engagement and self-care.

8. One of the most cited contextual barrier against patient engagement is a.

lack of time for patient-provider interactions.

b.

language barriers.

c.

lack of EBP.

d.

providers who wish to maintain control in health care decisions.

ANS: A

Lack of time for patient-provider interaction is cited repeatedly in the literature as a contextual barrier against patient engagement.

TRUE/FALSE 1. Health literacy is best described as an individual’s ability to access, interpret, and understand quantitative data.

ANS: F

Health literacy is an individual’s ability to access, interpret, and understand qualitative data.

2. A patient portal is a web-based platform which compiles various resources for patient engagement such as decision-making aids,

educational materials, and communication applications which are typically connected to the electronic health record.

ANS: T

A patient portal is a web-based platform which compiles various resources for patient engagement such as decision-making aids, educational materials, and communication applications and is typically connected to the electronic health record and is used by their providers to provide health care data back to the patient.

3. The core of evidence-based practice is placing cost reduction at the center of all care decisions.

ANS: F

Putting the patient, whether individual, family or community, at the center of all care decisions is the core of evidence-based practice.

3

4. By keeping EBP patient-centric, the filter for interpreting and applying evidence in the contextual world in which that patient lives

to achieve health.

ANS: T

Matching strategies for engagement that address individuals of all levels of health understanding and targeting how they want or believe they can be engaged in their care is necessary when behavior change or self-management is the goal.

5. By giving up their own centricity, providers can feel more professionally fulfilled by managing patient health instead of patient

flow.

ANS: T

Patient engagement has been deemed a potential “blockbuster drug” and unfortunately has been underutilized.

6. Shared decision-making gained traction in the health care industry when shifts in payment model from a fee for service payment

structure to a pay for performance structure based on value occurred.

ANS: T

In the emerging value-based delivery system there is increased focus on providing quality care at a low cost for populations.

4

7. A level 5 is considered to be the highest proficiency attainable for The Program for the International Assessment of Adult

Competencies (PIAAC).

ANS: T

Participants are scored in the PIACC survey with “proficiency levels” from levels 1 to 5, with “below level 1” being the lowest level of problem solving/proficiency, and “level 4” as the highest proficiency.

8. Asking patients what they already know and understand to assess that understanding can allow patients and providers to enter into

conversations with a more-equal knowledge base.

ANS: T

Asking patients what they already know and understand and using teach-back methods to assess that understanding can allow patients and providers to enter into conversations with a more-equal knowledge base breaking down individual barriers against patient engagement.

9. When patient-centered care is provided appropriately, the patient makes all decisions independently.

ANS: F

When patient-centered care is provided appropriately, patients are allowed to decide their own treatment course with the support of educated and invested health care providers.

Evaluating the potential cost savings of an EBP using selected outcome measures such as additional costs of care delivery associated with adverse events

b.

Actual cost reduction with use of EBPs

c.

Cost-benefit analysis evaluating the benefits of an EB intervention on outcomes in relation to the cost of delivering the EB intervention

d.

Patient satisfaction with the EBP intervention

ANS: D

Patient satisfaction with the EBP intervention would be considered an outcome measure of the EBP intervention. All of the other options are appropriate methods to address fiscal outcomes of implementing EBPs. 9. When preparing a summary report of your EBP work for executive leaders and QI program members, the report should a.

be brief, about 2 to 3 pages.

b.

include statistical process control charts in the body of the report.

c.

avoid inclusion of names of individuals who worked on the project.

d.

focus on the positive experiences during the project.

ANS: A

A summary report of your EBP work should be written for your executive leaders and QI program members. The report should be brief about 2 to 3 pages. Impact on quality of care can be appended to the report illustrating improvements using statistical process control charts. Lessons learned including both positive and negative experiences during the project as well as the names of the project team members and leader should be included.

10. Which statement by a new researcher regarding evaluating the impact of implementing evidence-based practices indicates that

further explanation is needed by the mentor? a.

Fiscal outcomes may include cost saving, cost reduction, and cost-benefit analysis.

b.

Evaluation includes process measures only.

c.

A common approach used for evaluation is a prospective pre-post-implementation design.

d.

Process measures reflect staff’s use of EBPs and whether the EBPs demonstrated to benefit patients are followed correctly.

ANS: B

Evaluation must include both process and outcome measures. The other statements are true.

TRUE/FALSE

1. Evaluation is a structured approach to evaluate the impact of EBPs prior to implementation of the EBP in practice.

ANS: F

Evaluation is a structured approach to evaluating the impact of EBPs when implemented in practice. It includes collection and analysis of data from the practice setting to determine if the EBPs should be retained, modified, or eliminated.

3

2. Process measures evaluate staff’s use of the EBPs as detailed in the local EBP standard. They measure whether the EBPs

demonstrated to benefit patients are being followed.

ANS: T

Process measures evaluate staff’s use of the EBPs as detailed in the local EBP standard. They measure whether the EBPs demonstrated to benefit patients are being followed.

3. Outcome measures are those projected to change as a result of implementing the EBPs. They are used to evaluate whether

implementation of the selected EBPs are resulting in improvements in health outcomes.

ANS: T

Outcome measures are those projected to change as a result of implementing the EBPs. They are used to evaluate whether implementation of the selected EBPs are resulting in improvements in health outcomes.

4. Fiscal measures are estimated health care costs that may be impacted by implementing EBPs and include cost savings only.

ANS: F

Fiscal measures are estimated health care costs that may be impacted by implementing EBPs. Fiscal measures can address cost savings, cost reductions, and cost benefit.

4

5. When EBPs are implemented in the practice setting by multiple clinicians, the sample of subjects is most likely homogenous.

ANS: F

When an investigator is implementing a study protocol, the environment is controlled with a homogenous sample of subjects. When the EBPs are implemented in practice settings by multiple clinicians the patient population is heterogeneous.

6. A common approach used for evaluation is a prospective pre-post-implementation design.

ANS: T

A common approach used for evaluation is a prospective pre-post-implementation design. Using this format, baseline measures are collected prior to implementation to compare with the same measures at post-implementation.

7. Outcome measures do not reflect care processes but the actual results of care delivered on patient outcomes.

ANS: T

Outcome measures do not reflect care processes but the actual results of care delivered on patient outcomes.

8. Measuring outcomes alone without also measuring process of care is not recommended.

ANS: T

Improving outcomes requires improving care processes.

9. When outcomes do not improve the conclusion is that the EBPs are not working.

ANS: F

When outcomes do not improve there may be too much variability in implementation of the EBPs and thus the impact on outcomes may be limited. A measurement of both process and care outcomes is necessary to fully evaluate the EBP. 10. Individuals who have participated in implementing the EBP protocol should be excluded from implementing the changes in

practice to avoid bias.

ANS: F

Individuals who have participated in implementing the protocol can be very helpful in evaluation by collecting data, providing timely feedback to staff, and assisting staff to overcome barriers encountered when implementing changes in practice.

Chapter 17: Dissemination LoBiondo-wood: Evidence-Based Practice for Nursing and Health Care Quality Improvement, 1st Edition

MULTIPLE CHOICE

1. Which of the following is a component of passive dissemination of EBP projects? a.

One-way communication

b.

Real-time interaction

c.

Bi-directional communication

d.

Multiple conversations

ANS: A

Passive dissemination can be described as a one-way communication or top down process such as publishing, or posting information with the expectation that the intended audience will access and use the information. Active dissemination is characterized by real-time interaction with the intended audience to impart key messages or information, the dissemination is bi-directional communication and multiple conversations are used to discuss EBPs and rational for use.

2. When analyzing evaluation data from an EBP project intended to promote teamwork and interdisciplinary communication, it is

important to reflect on the intended audience to disseminate information and intervention materials by a.

sending the results to the appropriate national organization for approval.

b.

tailor the report to the intended audience.

c.

create a specific report for each discipline involved in the EBP.

d.

share results with the chief executive officer of the organization who will determine if the EBP results are appropriate.

ANS: B

As EBP evaluation data is analyzed, it is important to identify the intended audience because objectives, methods, and venues for dissemination need to be tailored to the intended audience. It is not necessary to send the results to a national organization or organizational leader for approval. If the EBP project was intended to promote teamwork and interdisciplinary communication including members of multiple disciplines, one report should be developed to possibly impact interprofessional teamwork efforts.

3. When developing objectives for dissemination of EBP information to key senior leaders it is most important to a.

include information on how nursing procedures could be adapted to other areas.

b.

discuss strategies for sustainability.

c.

develop a detailed 10-page report.

d.

illustrate improvements in both quality and cost.

ANS: D

Improvements in both quality and cost would be an appropriate objective for dissemination to key senior leaders. Staff nurses on the unit where the EBPs are implemented may include illustrations of how their contributions have improved process of care and outcomes including how nursing procedures could be adapted to other areas as well as a discussion of strategies for ongoing sustainability. Busy clinical leaders are more likely to read short 2-page executive summaries with details rather than a 10-page project report.

4. When preparing a poster to disseminate your work on an EBP, the nurse researcher should a.

include all specific details of the EBP project on the poster.

b.

create a story board of key information.

c.

avoid a sustained presence by the poster to allow individuals to read content alone to determine their own opinion of the work.

d.

follow guidelines of Times New Roman 12 point font for all of the poster to make best use of space.

ANS: B

A poster presentation is a story board of key information. The design and layout of the poster is important to consider because it will draw people to read and possibly discuss you work therefore at least one member of the team should be available to discuss poster content. Presenting a poster is a social and interactive experience.

5. You are serving as a mentor for a school nurse practitioner who is preparing an oral presentation to disseminate findings from an

EBP focusing on use of social media to assist teens in smoking cessation. The audience is the National Association of School Nurses. Which statement by the School NP indicates the need for continued discussion of the oral presentation process? a.

I will time the talk so the audience has about 2 minutes to ask questions.

b.

I plan to practice the presentation so I keep to the time limit.

c.

I have developed a 25-word summary of my work and its impact that I plan to use as part of my talk.

d.

I have omitted information about the complex methodology used for the EBP from the talk.

ANS: A

Oral presentations are always timed and generally last for about 15 to 20 minutes. The talk should be timed so the audience has 5 minutes to critique or ask questions about your work. The audience generally wants the speaker to get to the point. The talk should not be burdened with conceptually or methodically complex discussions. When preparing the talk, it is best to define the central message and do your best to develop a summary of your work and its impact that you can state in 25 words or less. You should practice the presentation being mindful of the time allocated for your talk.

6. Which one of the following statements regarding publishing to disseminate findings of EBPs should the nurse researcher take into

consideration? a.

Publishing findings of EBP generally is much less time consuming compared to preparing a poster.

b.

Publishing your work in a peer-reviewed journal provides a high level of creditability to your work.

c.

When publishing having grammar experts review and comment on the paper.

d.

It will not be possible for others to replicate your work when publication is used to disseminate EBPs.

ANS: B

Publishing your work in a peer-reviewed journal provides a high level of credibility to your work and makes your work available to a larger audience than oral or poster presentations. Preparing your work for publication is time consuming and can be a tedious process. Having subject matter experts review and comment on your work is a cornerstone of the peer review process. Publication is an important vehicle to promote replication of your project.
