Research - Data analysis: Nursing

Nurse Luis works in urgent care and a staff nurse named Katie brought it to Luis' attention that the nurses there don’t always introduce themselves when assuming care for clients. She said, “I’ve noticed that sometimes the nurses at our urgent care forget to introduce themselves when going into a client’s room. I find myself forgetting to do this too, I wish there was something that would remind us to do it more consistently.” After speaking to several other nurses, Nurse Luis decided to do a research study focused on the use of pop-up reminders for nurses to introduce themselves each time they access a client’s electronic health record. Nurse Luis collected quantitative data by using a survey that asked clients to document the number of times the nurse introduced themselves when they entered their room, and qualitative data by interviewing nurses about their experience with the introduction reminder. Now it is time for Nurse Luis to analyze all the data he’s collected.

Data analysis is the systematic process of applying different techniques to describe and evaluate information that the researcher has collected. Data analysis can be one of the most exciting steps of the research process since the researcher is finally able to find answers to their research question! Whether your study is quantitative, qualitative, or a mixture of both, you will use data analysis techniques to understand the findings. All right, there are different ways to analyze data, depending on the type of data that was collected. Quantitative research analyzes numerical data through descriptive and inferential statistics. Descriptive statistics allow researchers to describe, organize, and summarize characteristics of data. For example, Nurse Luis included descriptive statistics about the number of years the participants in his study have been a nurse, and this could help bring more insight into the study findings.

On the other hand, inferential statistics allow researchers to draw conclusions and generalize findings. In this case, Nurse Luis was able to show the success of the pop-up reminder by comparing the survey results from clients whose nurse had the pop-up reminder enabled, to clients whose nurse did not. Changing gears, data analysis for qualitative research tends to be more subjective, consisting of narrative information rather than numerical data. Qualitative data includes interview transcripts, observation notes, diary entries, nursing records, and audio or video recordings. When you analyze qualitative data, the focus is on exploring participants' values, beliefs, and experiences. To do this, the researcher begins by performing data coding where they look for narrative patterns throughout the data and categorizing them into groups. For example, Nurse Luis noticed that many participants made comments like “I don’t have time to introduce myself” and “I have too much work to do,” so he decided to code all similar comments as “workload issues”.
