RESEARCH DESIGN AND STATISTICAL CRITIQUE

In the article “A Qualitative Study of Phlebotomy Device Selection”, Downing has enlightened the phenomenon of choosing a device through decision process staff. In order to carry out the study, the author has used purposive sampling technique that will verify the gap between the correct device and reported practice. Purposive sampling is a non-probabilistic strategy for collecting valid data, especially for small samples and very specific. It has been mentioned in the methodology of the article that author has meaningfully selected the sampling method as he wants to gather a heterogeneous sample that contains CAs and nurses from acute care units located in a large metropolitan hospital, the hospital's institutions have approved the study. Participants in the study were interviewed in private room, they were asked to recognize the type of instrument or device they usually used to collect the sample of blood and also provide the reason behind their selection. Phlebotomy involves the extraction of blood from the veins by a health care professional who is known as a phlebotomist. The author in the article has discussed the involvement in the extraction of blood from the body or vein with exact precision. When blood is drawn from the body, is made for medical examination and various tests. It is not as simple a process as it might seem, because it involves good practices and knowledge similar to the knowledge that is required by medical specialists and doctors.

However, this practice varies considerably from one country or one institution to another or from one individual to another in the same country. Authors in the article have explained that the differences may relate to the sampling technique, training (theoretical and practical), the use of safety equipment, methods of disposal, reuse of materials and the availability of the vaccine against hepatitis B.

This means that, like any other career, you start with a low salary or income and as you become more experienced and professional in the field, you will be able to take advantage of the career as a phlebotomist.

In the article “A Qualitative Study of Phlebotomy Device Selection”, the authors have used qualitative design. Qualitative research is often seen as a precursor to quantitative research, in that it is often used to generate leads ...
