The collection of facts that are true, through intense research is called evidence. Therefore, there are different levels of evidence in the form of a pyramid to determine the validity of any research from the lowest being the weakest to the highest being the most authentic. However, as much as there is a level of evidence, there is not one standardized way of interpreting evidence. The level of evidence also known as the hierarchy of evidence is used as a guide to the various types of research that could be performed and helps to place them in categories, so that if the research is conducted properly, the answers will be most reliable (Melnyk, & Fineout-Overholt, 2018).
The highest-ranking level of evidence is the quantitative research which is the systematic review of the randomized control trials (RCT). It gives the best answer for what caused a situation and the effect of the situation because it synthesizes several studies compared with the lower levels of evidence which is based on descriptive and case studies, expert opinions. It is the strongest research method that produces the same results from multiple studies to produce the same outcome results (Melnyk, & Fineout-Overholt, 2018).
The DPI project that I have chosen is about finding out what is causing the reoccurrence of stroke and how it can be prevented. In my facility, there are many patients who are readmitted for stroke reoccurrence. So, the first article is a prospective study that is attempting to discover the clinical and the neuro imaging aspects that may be contributing the reoccurrence of stroke in these patients after they had been treated and are on medications (Hervella, et al., 2021). They conducted a retrospective study with a large number of people and it is primary research because there was ongoing observation and participation by the researchers and the participants (GCU, 2022).
The second article is also primary research because it is a summary of the study data that was conducted by others (GCU, 2022). Though the method used was the RCT method that was taken from a multiple center randomized double blind controlled trial. The purpose of the article was to asses the effect of the medication aspirin to prevent the reoccurrence of stroke compared to the other medicine nicametate and to identify the cause of stroke recurrence (Wang, et al., 2021).
These articles demonstrate support for my DPI project to find what is causing stroke reoccurrence and what interventions that needs to be taken to prevent the stroke reoccurrence.
