Purpose
a. The purpose of the Koh, Wang, Richards, et al (2015) study is clearly stated as being to develop and examine the effectiveness of an advance practice nurse-led telehealth on readmissions and health-related outcomes among patients with post-acute myocardial infarction postdischarge, (p. 1357). The authors also point out that the overarching issue is that cardiovascular disease remains the leading cause of death worldwide, necessitating greater insight into evidence-based preventative solutions. Furthermore, the authors propose a telehealth-based advance practice nursing intervention.
Critique
b. The researchers clearly identify the population (high-risk patients admitted to a hospital in Singapore with an episode of AMI), the variables (readmission after 1000 days of discharge, cardiac self-efficacy, anxiety and depression, and quality of life factors), setting (various, including the initial single...
Everything about this research design is feasible.
Research Design
c. A randomized, two-armed parallel controlled trial, this study fits the criteria and the authors explain exactly how they applied randomization methods and controlled for other variables.
d. After being screened for eligibility, the participants were randomly assigned to the experimental group using numbered envelopes.
e. The type of sample included patients admitted...
…program parameters.
k. This study has few limitations. A few of the outcome measures do not have known reliability, such as the heart self-efficacy instrument. Also, the researchers are trying to measure a cluster of dependent variables instead of focusing on a few. The research does not necessarily illustrate exactly what features of the telehealth program were helpful for the participants, and if those features could have been easily delivered some other way.
l. The findings of this study have tremendous implications for telemedicine practice. Reducing readmissions is a major goal in heart health practice, leading to cost savings as well as improved…
