Locating and Appraising Research
Telehealth has been one of the cutting-edge features of modern nursing practice that
enables remote patient monitoring, speeds up access to care, and enhances patient outcomes. As
technology becomes increasingly synonymous with healthcare delivery, nurses have to learn
effective research and critical appraisal skills to enable application of valid, evidence-based
information. A person must look for credible sources via legitimate databases such as PubMed,
CINAHL, and the Cochrane Library in an attempt to support clinical decision-making. This
paper explores means of searching and determining quality telehealth research with emphasis on
how database literacy, critical appraisal, and evidence-based practice are able to advance the
profession of nursing.
Interview
A phone call interview was conducted with Dr. Dion Whitehead, RN, BSN, MSNed, FNP-
C, PMHNP, DNP (personal communication, October 8, 2025). Advanced practice nurse and
nurse educator Dr. Whitehead emphasized the importance of making use of credible databases
and current literature while looking for telehealth topics. He described his default resources as
the American Telemedicine Association, Centers for Medicare & Medicaid Services (CMS), the
Journal of Telemedicine and Telecare, and The New England Journal of Medicine. These
resources, Dr. Whitehead said, provide both policy guidance and peer-reviewed evidence to
guide the construction of nursing practice in telehealth.
Dr. Whitehead also discussed methods of appraising evidence. He encouraged prioritizing
research credibility, sample size, and study design over conclusions. He encouraged the use of
nursing students in applying Boolean operators as well as date limits in retrieving peer-reviewed
research that is most relevant and credible. His comments emphasized discrimination between
, quality evidence and poor-quality evidence as well as between database search that aligns with
research objectives. His perspective reaffirms that quality literature review is an ongoing process
that can improve the evidence base of nursing practice. Additionally, Dr. Whitehead noted how
telehealth studies are becoming more interdisciplinary and engaging between nursing,
technology, and policy arenas.
He encouraged nurses to look for not just randomized controlled trials but even mixed-
method studies with patient experience and provider feedback reported. He explained that quality
research must include results like patient satisfaction, reduced hospital readmissions, and cost
savings. Dr. Whitehead's remarks confirmed that evidence-based practice in nursing must stay
updated with the latest technology and that close scrutiny of telehealth data bridges the theory-
practice gap.
Locating Resources
Identifying productive sources on telehealth begins with a focused question of inquiry and
identifying appropriate databases. These databases such as PubMed, CINAHL, Cochrane
Library, and PsycINFO are also well-known to be valid and comprehensive sources of peer-
reviewed health science literature. PubMed gives extensive coverage of biomedical and nursing
research while CINAHL addresses nursing and allied health fields (Oermann et al., 2021). Use of
advanced search features such as Boolean operators ("AND," "OR," "NOT") and Medical
Subject Headings (MeSH) terms increase the accuracy and relevance of searches. When making
assessments of studies, credentials of the authors, the reputation of the journal, and study design
are also considered.
Randomized controlled trials, meta-analyses, and systematic reviews are the best
information resources since they provide high levels of evidence (Agarwal et al., 2021).
