Description
To Prepare:
Review the Resources and identify a clinical issue of interest that can form the basis of a clinical inquiry.
Review the materials offering guidance on using databases, performing keyword searches, and developing PICO(T) questions provided in the Resources.
Based on the clinical issue of interest and using keywords related to the clinical issue of interest, search at least two different databases in the Walden Library to identify at least four relevant peer-reviewed articles related to your clinical issue of interest. You should not be using systematic reviews for this assignment, select original research articles.
Review the Resources for guidance and develop a PICO(T) question of interest to you for further study. It is suggested that an Intervention-type PICOT question be developed as these seem to work best for this course.
*Library tip:
Walden Library recommends starting your search broadly with one concept or search word and adding more elements one at a time. Depending on your topic, the evidence will not necessarily address all the aspects of your PICO(T) question in one article. Select the most important concepts to search and find the best evidence available, even if that means assembling evidence from multiple articles.

Post a brief description of your clinical issue of interest. This clinical issue will remain the same for the entire course and will be the basis for the development of your PICOT question. Describe your search results in terms of the number of articles returned on original research and how this changed as you added search terms using your Boolean operators. Finally, explain strategies you might make to increase the rigor and effectiveness of a database search on your PICO(T) question. Be specific and provide examples.

Why you chose this
article and/or how it
relates to the clinical
issue of interest
(include a brief
explanation of the
ethics of research
related to your clinical
issue of interest)
This article was
selected because it reports
the findings of action
research study on
interventions to reduce
medication errors. The
article is a peer-reviewed
journal article on various
interventions for medication
errors. It relates to the
clinical issue of interest
because it focuses on
means to address errors.
The study observes the
ethical consideration of
autonomy and informed
consent. This relates to the
research participants’ right
to withdraw from the study
at any moment.
This article was
selected for its contribution
to the research on solutions
to reduce medication errors.
It is a randomized controlled
trial on medication error
interventions to reduce
interruptions during
medication administration.
The article provides
evidence regarding the use
of ‘do not interrupt’ vests in
medications administration.
A potential ethical issue in
this study is the
confidentiality of patients’
information and data. All
data in the study was
processed anonymously
and participants’ identity
was protected.
The rationale for
selecting this study is its
reporting on factors
associated with medication
errors. It was selected
because it outlines
important factors to consider
in order to reduce errors. It
relates to the issue of
concern by outlining factors
leading to the problem of
medication errors. As a
retrospective evaluation, the
article has few ethical
concerns. However, it is still
necessary to ensure
informed consent is
obtained from the
participants. This study
presents no need for
informed consent.

This study was selected
for the project because of its
focus on medication
administration errors. It
contributes to the current
project by identifying a
potential intervention to
reduce errors. The topic of
medication errors is
associated with patient
harm and this article was
selected due to its potential
to reduce errors and hence
harm to the patients. The
study recruited pediatric
patients, a vulnerable
population. It is essential to
consider the rights of the
children and potential
impact of research on their
well-being. This study
presented no foreseeable
harm but also included
ethics approval.
The purpose of the
study was to improve
medications safety by
reviewing effectiveness of
an intervention. The
intervention was doublechecking, a process for
nurses to separately check
information and then share
it. The researchers identified

Brief description of
the research
methodology used
Be sure to identify if
the methodology used
was qualitative,
quantitative, or a
mixed-methods
approach. Be specific.
The methodology used
was action-research using a
quantitative research
approach. Quantitative
research involves statistical
data and hypothesis testing
(Hoare & Hoe, 2013). In this
study, for instance, the main
outcome is the rates of
medication errors reported
as errors per 1,000
prescribed medications. The
researchers evaluated the
rates of errors before and
after the interventions,

interruptions and
consequently led to safer
medication administration.
This study focuses on a
potential solution to reduce
medication administration
errors in the ward.
The study was
conducted using a
quantitative methodology.
Specifically, it is defined as
a multicenter cluster
randomized controlled trial.
In this methodology, the
study was conducted by
randomly selecting hospitals
to participate in the study. A
comparison of pre- and
post-intervention rates of
errors in the intervention
and control groups was
conducted. Data was
analyzed using descriptive
statistics approach.

there is little risk of bias as

a retrospective audit and

is valid since specific
records for medication

reporting were maintained
and used in this study.
Similarly, it is reliable

used and its reliability is
high, about 0.83 alpha level.
It has also acceptable

presents an important
contribution in the
evaluation of doublechecking interventions.
