A limitation of both studies is that no recognition of the diagnostic quality of the images, so whilst more patients are finishing their exams, they may still be required to rebook with sedation to improve image quality, as previous studies have shown that anxiety can increase movement. The study by AlRowaili et al (2016) identifies a clear study aim investigating the factors affecting MRI no-shows and rescheduling of appointments. The study employs an analytical cross-sectional study, which is an appropriate method for collecting qualitative data specific to investigating the relationship between outcomes and affecting variables of interest in a defined population. It also has the benefit of being functional over a short time frame or …show more content…
Again there are limitations of the finding. The most concerning is the sample size. The low participation rate of 13.3% was not acknowledged or that the authors considered extending the study length to help improve recruitment. This may introduce random error from sampling variability, which increases as sample size decrease (Pannucci and Wilkins, 2010). Failure to recruit may arise from the potential inexperience of the researcher chosen to collect approach patients and administer the questionnaire. The researcher is described as an undergraduate student. It is assumed that the researcher has limited experience working with patients and so may not interact or emphasise with patients as well as a seasoned researcher (Pannucci and Wilkins, 2010) This may have had an adverse effect on participation rates, introducing interviewer bias (Pannucci and Wilkins, 2010). A clear weakness of the paper by AlRowaili, et al (2016), is not with the research itself, but more of the cultural differences highlighted in the text, which indicate could play an important factor in the rate of no-shows. Due to these differences, the stand-alone results cannot be considered generalizable to MRI departments within the United Kingdom, although all healthcare services, including MRI, are free to all Saudi Arabians, which correlates with healthcare provision in the UK. Findings from the study by AlRowaili, et al
Some patients, particularly those who experience “scanxiety”, may not be familiar with the unique features the machine offers and will have questions about this and other MRI options.
The researchers used purposive sample but did not give any explanation as to why this choice sampling was made. It is essential to describe the sampling process in a research where this facilitates the reader to distinguish any bias in the whole sampling process. In studies using participants, the process of how to select, access, inform and retain research participants requires considerable thought. Sampling is a key issue, because it is
· Based on your review of the statistics in the study, do you agree with the study’s conclusions? Why or why not?
The results of the study were not useful to the population over a months’ time but over the years the study many show signs of progress (Rolleri, Wilson, Paluzzi, and Sedivy, 2008).
However, there are several limitations to this study. One, the sample size is small, and there results may not generalize to other populations. Second, the study was conducted for only six
"The new improvements are designed to address those issues. Try to alleviate some of the fears, try to make them feel more comfortable, more in control of their environment while they're getting an MRI. They can choose their lighting, their sound, the video they watch. They can also play DVDS if we have one that they like," says MRI Team Leader Shelia Turner.
She also briefly brought up a point on how MRIs can symbolize inequality as getting a MRI shows that you have access to the best of
The authors relied heavily on two studies to create their argument. The first study mentioned was the Pinto et al article. In this study, "Pinto and colleagues (5) assessed the
First week at High Point Regional Hospital was a bit nervous. I didn’t know how the technologists there would interact with me. I worked with Kim, Sonya, and Debbie. All of them seems alright to me. On Tuesday, I didn’t scan anything, I mostly observed the technologists. I helped prep the room, wiped down the table, and put on a new sheet on the table . I’ve learned that the way they scanned their lumbar spine here are different than in Lexington Medical Center. Here, when scanning lumbar, it should only cover 5 disk space, top and bottom field of view (FOV) doesn’t overlap. High Point Regional Hospital has 2 MRI machine; a Siemen Espree and the old Siemen Symphony. Lexington Medical Center has Siemen Aera (newer machine), images are
The framework that will be used to critique the above research paper is Coughlan, Cronin and Ryan (2007). This framework has been chosen because it is easy to follow and is routinely used to critique quantitative research studies (Fothergill and Lipp, 2014).
Cullen and Gendreau compare and contrast the many studies on this subject, the meta-analyses conclusions, their strengths, weaknesses, inconsistencies, and the trends that follow the studies
This study was limited due to the small sample size. Although the conclusions are valid, more research with a
To patients whose are diagnosed with first clinical treatment and the MRI results show clinical exacerbations
These studies only included undergraduate students, therefore consisting mainly of young adults. This raises questions on whether results can be generalised to those in all age groups.
The author’s claim appears to be misleading because it is not clear who the 71% adults are, not enough evidence or broken down into categories. For example, gender, geographic location, adult professionals or otherwise, and ethnicity. Bluman, 2005 claims, that “When interpreting results from studies using small samples, convenience samples, or
