Answer 2 for DNP 820 Compare and contrast qualitative, quantitative, and mixed-method research

Quantitative research is a type of research method that demonstrates measurement and accuracy while making use of a rigorous and controlled design to examine phenomena. The series of applications of quantitative research may be observed in clinical trials for new treatments and medications to surveying nursing staff and patients. The design type is further designs include experimental, quasi-experimental, and non-experimental. While Qualitative research centers on lived experiences and human perceptions using multiple ways to collect data. The qualitative method of research is categorized as ethnography, phenomenology, grounded theory, historical research, and case studies. The mixed research method allows for inferences of data from both quantitative and qualitative research by analyzing data and integrating the findings (Rutberg and Bouikidis, 2018). While both quantitative and qualitative approaches are important quantitative research is most recommended for the DPI project for statistical validity.

Based upon the hierarchical strength in the level of evidence pyramid, translating evidence into practice with evidence from the higher ranked level is crucial. Melnyk  (2016) describe systematic reviews of randomized controlled trials as the strongest level of evidence to guide interventions in clinical practice but added that randomized controlled trial could substitute for the former in their absence in order of strength in supporting level of evidence. The formation of a PICOT question is a pivotal guide in locating the most appropriate data and evidence to support the translation of evidence into improved practice. This level of evidence applies to my DPI project as it is geared toward the best treatment approach for asymptomatic urinary tract infections. Using critically appraised results from a systematic review of randomized controlled trials or randomized clinical trials establishes the best-proven evidence that can be applied to improve clinical practice. It is important to note that the article’s validity, reliability, and applicability are vital in influencing the change of practice (Melnyk, 2016).
