Quantitative research can be described as the research process that uses collection and numerical data analysis in research studies that generalize results to a wider population, while qualitative research uses involves collecting and analyzing non-numerical data such as interviews, questionnaires and the results are generalized for a smaller or localized population. (Bhandari, 2020). Quantitative research uses various methods for data collection, and these include experiments, observations which are recorded as numbers; and surveys/questionnaires with closed-ended questions.

Alternatively, qualitative research uses interview questions that are open-ended. Other data collection methods include observations that are described in words, literature reviews that explore concepts and reviews (Bhandari, 2020). In quantitative research, the focus is on testing theories and developing the hypothesis, data goes through statistical analysis in numerical and graphical expressions, and requires many respondents answering closed-ended questions

Qualitative research on the other hand focuses on exploration of ideas and formulation of theories or hypothesis. It is analyzed by summarizing, categorizing, and interpreting and mainly expressed in words. Qualitative research requires a few respondents and open-ended questions (Streefkerk, 2019).

Quantitative research will create a major impact on my proposed DPI project because believe that this will help improve patient outcome, save cost of treatment , and provide evidence-based practice for the facility and who knows our sister facilities.

Great Post Carolyn, To add to what you have written, in the article by Chalmers, & Cowdell (2021), he points out that qualitative research needs to be more prevalent in health literature journals because there is a need to expound on the role of human nature and the structural contexts in the lives of individuals. Quantitative research has been used more often because it has a more scientific edge and rigor compared to qualitative research. Likewise, Gilad (2021), in his article is also encouraging quantitative researchers to consider the limits in their research from the lack of the qualitative piece of research, that there are advantages to mixing both methods to enrich the research. The interests of most researchers towards the qualitative method have been because off the training that they have undergone from their past professors and PhD holders who have always emphasized on Qualitative research as the most scientific method (Gilad, 2021).

Qualitative research is mostly developed out of the need to solve and issue. It is holistic working with the whole

patient and family as a whole being and it is detailed and uses many ways to collect information. Nurses use this method to find ways to help patients based on their preferences. It sets the plan for future research by using quantitative or qualitative research with people experiencing and interpreting data differently based on the factors that has affected them, the truth about this research is that it is a composite of different realities (Chicca, 2020). This method still requires the researcher to follow a strict process of research by planning and finding an interesting topic, design with expansive data collection methods that will enhance the quality of the work, the researcher should bracket any personal ideas, views, biases and assumptions (Chicca, 2020).

Qualitative and quantitative research are both essential to nursing science. In general, qualitative research refers to studies that cannot be quantified or expressed numerically such as qualities, opinions, or feelings (Wienclaw, 2021). Data can be collected through participant observations and interviews in qualitative research. On the other hand, quantitative research refers to observations that are measurable, expressed numerically, and can be quantified into hard facts (Wienclaw, 2021). Data can be collected through various experiments, tests, simulations. The general goal of quantitative research is to generalize results to a larger population to explain a phenomenon with numerical data collected from a smaller group (Wienclaw, 2021).

Quantitative research articles are required for the DPI project as it provides the numerical data needed to support the changes being made. With this, the variables used in quantitative research provide numerical data that can be further analyzed and used as statistical tools for implementing change (Wienclaw, 2021).


In the study by Ramer et al. (2016), a randomized controlled trial was used to determine the efficacy of utilizing a VeinViewer when inserting peripheral intravenous catheters. The study included 53 participants who were randomly divided into two groups: the Veinviewer group and the standard group. Overall, results showed that nurses who used the Veinviewer had less procedural time and fewer access complications. The study qualifies as quantitative research as it included variables that are quantifiable numerically.

Quantitative research uses variable-based models that are abstract from different cases and qualitative research favors case-based models that abstract from different characteristics. These “mixed methods” approaches treat qualitative and quantitative research as complementary, rather than opposing strategies (Creswell, 2015). Quantitative research uses large samples, random sampling from an abstract population. Qualitative research usually uses strategy of generalization that relies on exploration of theoretically sampled cases.

Sepsis has been recognized as the leading cause of death in non-coronary ICUs. To understand the impact on sepsis and septic shock, nurses need to know the signs and keep up to date with the latest evidence-based best practices (American Association of Critical Care Nurses [AACN], 2019). Using a sepsis bundle for early detection of severe sepsis or septic shock can result for a positive patient outcome. One study looked at the feasibility of using screening tools in an intensive care unit to determine if a patient was becoming septic. (Coleman & Jackson, 2014).

Quantitative research has a vital role for my proposed DPI project because I believe that this will help improve patient outcome and decrease length of stay in the hospital. It will be completed by questionnaires, face to face interaction, all clinicians will be included and data can be collected by group sample in the unit. Pre and post data collection will be collected and evaluation at the end will reveal if it will be a success project or not. Descriptive statistics will be measured and graph will be tallied for pre and post implementation of the sepsis bundle. External validation studies are necessary to confirm the treatment practice and early medical management for patients. Using available data in ICU can predict accurately by nurses utilizing sepsis bundle prior to clinical finding. Sepsis bundle have been reported to improve survival rate and improve patient health.
