The document examines three research articles on fall prevention among the elderly and discusses their levels of evidence. Article one presents a quantitative study evaluating the impact of a clinical supervision model on fall risk, which is rated a level III evidence. Article two evaluates the impact of an educational intervention program on fall prevention and is also rated level III evidence. Article three examines the prediction of post-stroke falls using balance assessments and is rated level II evidence. The levels of evidence are based on the study designs and whether randomization was used.

1. Prevention of Falls among the Elderly.
Prevention of Falls among the Elderly. Levels of evidence are classified into five hierarchical
divisions. Evidence in each level is dependent on the applicability, validity and quality of the
methodological design as applied to patient care. The strength of the recommendations
made by a research study is given by the above decisions. The Canadian Task Force on the
Periodic Health Examination described these levels through a 1979 report which sought to
develop recommendations based on medical literature evidence. According to the report,
the effectiveness of an intervention is determined by the system of rating developed by the
authors. This paper seeks to examine three research articles on fall prevention among the
elderly and discuss their levels of evidence.Prevention of Falls among the Elderly.ORDER A

Improving the evaluation of risk of fall through clinical supervision: an evidence. Procedia-
Social and Behavioral Sciences, 217, 382-388.This article presents a quantitative research
on the fall risks. It seeks to provide evidence on the quality and safety of nursing through
the improvement of provider skills and implementation of clinical supervision. The research
was conducted between March and May 2014wit a convenient participating sample of 132
participants. The research is guided by nursing evaluation perimeters and concludes that
prioritization of hospital fall prevention is essential in reducing safety risks. Moreover, Cruz,
Carvalho and Lopes (2016) note that clinical supervision supports the nursing team, raises
awareness and reflection and also ensures the safety and quality of patient care.This
quantitative research is an original study by Cruz, Carvalho and Lopes conducted in 2016. It
focuses on determining the impact of the implementation of healthcare quality indicator
and clinical supervision model on hospital fall prevention.Prevention of Falls among the
Elderly.The level of evidence presented in this article is Level III. This is because; it is a
quantitative, descriptive and correlational study that uses questionnaires from the
convenient samples. The samples were also not randomly selected but instead were
selected based on the presence of a patient within the site of study. As such, this is a
controlled trial with no randomization that falls under the level III evidence category. Level
III evidence contains evidences acquired from well-designed controlled trials without
randomization that is quasi-experimental. Cruz, Carvalho and Lopes (2016) selected the
convenience sample of 132 participants who were admitted within the study period. The
research also sought to determine whether there was a statistically significant relationship
between age,sex, physical restraint and interventionswith fall risks in hospitalized patients
and the results were quantitatively presented.Prevention of Falls among the Elderly.Article

2. 2Ott, L. D. (2018). The impact of implementing a fall prevention educational session for
community‐dwelling physical therapy patients. Nursing open, 5(4), 567-574.This article by
Ott provide a research about the implementation of education session interventions as an
intervention for fall prevention among the community dwelling individuals undergoing
physical therapy. The aim of the study is to evaluate the impact of educational settings on
use of fall prevention interventions, fall risk knowledge and the number of falls experienced
in the community among the physical therapy geriatrics.The study evidence falls under
Level III evidence. This is because; it is a characteristic of both qualitative and quantitative
research employing a mixed method study design. The pilot study is a well-designed
controlled trial without randomization. It is a pretest–posttest quasi‐experimental research
design that uses questionnaires to evaluate the outcome measures of the number of falls
sustained for 60 days post the educational sessions, number of participants implementing
fall prevention techniques and fall risk knowledge (Ott, 2018). Moreover the sampling was
convenient and non-random based on the geriatric attending physical therapy at the time of
study.Prevention of Falls among the Elderly.Article 3Lee, H. H., & Jung, S. H. (2017).
Prediction of post-stroke falls by quantitative assessment of balance. Annals of
rehabilitation medicine, 41(3), 339.This article presents an examination an evaluation of
characteristics of the postural instability in stroke patients and alsogives a prediction model
of post-stroke falls.The research uses participants with first eve stroke cases and postural
instability parameters such as postural sway velocity (PSV) and the weight bearing
asymmetry (WBA). Lee and Jung (2017), statistically assesses the participants using fall
related questionnaires and telephone interviews to obtain the results.The level of evidence
in this quantitative study is Level II. The research is a controlled trial employing convenient
sample of 71 participants derived from the 231 individuals who had experienced first time
stroke cases. The participants are selected based on a designed criterion that ensured that
they all were first time stroke patients admitted for rehabilitation therapy between August
2011 and December 2015 in the Boramae Medical Center (Lee & Jung, 2017).The results
present statistical evidence that the participants of the study increase the postural sway and
weight bearing asymmetry. The research is analyzed though multivariable logistic
regression analysis and Statistical Package for the Social Sciences (SPSS) and presented in
graph form for the tests conducted (Lee & Jung, 2017). As such, the research study uses a
pretest–posttest quasi‐experimental research design.Prevention of Falls among the
Elderly.Levels of EvidenceLevels of evidence are classified into five hierarchical divisions.
Evidence in each level is dependent on the applicability, validity and quality of the
methodological design as applied to patient care. The strength of the recommendations
made by a research study is given by the above decisions. The Canadian Task Force on the
Periodic Health Examination described these levels through a 1979 report which sought to
develop recommendations based on medical literature evidence. According to the report,
the effectiveness of an intervention is determined by the system of rating developed by the
authors. This paper seeks to examine three research articles on fall prevention among the
elderly and discuss their levels of evidence.Article OneChoi, S. D., Guo, L., Kang, D., & Xiong,
S. (2017). Exergame technology and interactive interventions for elderly fall prevention: a
systematic literature review. Applied ergonomics, 65, 570-581.This article presents a

3. systematic review of literature materials regarding exergaming and its applications for
elderly fall prevention. The study sought to determine the cognitive and physical function
impacts of exergame interventions on the elderly population. According to the study,
Nintendo Wii is the most common device for exergaming while Xbox Kinect is reported to
be the second during the prevention of falls (Choi, Guo, Kang & Xiong, 2017). Consequently,
it concludes that fall prevention exergame-based interventions improve the cognitive and
physical functions of the elderly compared to conventional physical therapy.Prevention of
Falls among the Elderly.The level of evidence in this article is Level III. This level of evidence
contains data collected from quasi-experimental, the well-designed controlled trials without
randomization. Quasi experimental research is dependent on the manipulation of
independent variables without the assignment of random order of conditions or conditions
to participants. They have experimental units, treatments outcomes and measures even
though they lack randomization. In this case, the article is based on multiple literature
sources which are selected according to their relevance to the study and not randomized
selection. Most of the articles used employ the quasi-experimental design and pre-post
control group design as well as mixed methods. These designs have been employed in the
research to study the impacts of exergames on the prevention of falls among the elderly and
hence the use of quasi experimental design makes the article fall under level III of evidence
(Choi, Guo, Kang & Xiong, 2017).Article 2Carande-Kulis, V., Stevens, J. A., Florence, C. S.,
Beattie, B. L., & Arias, I. (2015). A cost–benefit analysis of three older adult fall prevention
interventions. Journal of safety research, 52, 65-70.This article is about the cost benefits
associated with fall prevention in adults. It examines three older adults and seeks to identify
the effective, feasible community-based fall interventions with a positive return on
investment. The results of the study concluded that fall interventions have positive net
benefits.In general, the paper recommendsthe use of the Otago Exercise Program, Tai chi:

adults (Carande-Kulis et al., 2015).Prevention of Falls among the Elderly.The evidence of the
study falls under the level I class according to John Hopkins Nursing evidence-based
practice levels of evidence. This level is characterized by experimental studies, randomized
controlled trial (RCT),and systematic review of RCTs, with or without meta-analysis. The
study is experimental inthat it follows three adults wo are highly vulnerable to frequent
falls and analysis the effects of interventions employed in their cases with regard to the
economic value. On the other hand, it employs a randomized control trial .On the
effectiveness of intervention results. A comparison of the national data estimates helped
determine the medical cost of using the interventions.Article 3Tricco, A. C., Thomas, S. M.,

environmental assessment and modification, vision assessment and treatment and
combined exercise; combined clinic-level quality improvement strategies, calcium
supplementation, and vitamin D supplementation (Tricco et al., 2017). The results of the
study conclude that the use of interventions in healthcare reduces the risks of injurious falls

and the values of the caregiver as well as preferences.Prevention of Falls among the
Elderly.The article provides level III evidence. This is because; it is a non-experimental
study that employs a combination of randomized clinical trials (RCTs) and systematic
reviews with meta-analysis. RCTs were used to examine fall prevention interventions for
the geriatric population aged 65 years and above in acute care and community settings
(Tricco et al., 2017). The comparison measures included placebo, fall prevention
interventions and usual care. The systematic review followed a guidance statement
developed by the Preferred Reporting Items for Systematic Review and Meta-analysis
Protocols (PRISMA-P) (Tricco et al., 2017). The results were briefly described and extended
through a network meta-analysis that ranked all the available interventions for fall
prevention and their combinations.Prevention of Falls among the Elderly.
