Which of the following is an example of qualitative research in EIP?

Qualitative research in Evidence-Informed Practice (EIP) focuses on understanding the experiences, perspectives, and meanings that individuals attach to certain phenomena. Option C, which involves interviews or focus groups analyzing patient experiences and preferences regarding treatment, exemplifies this type of research as it seeks to gather in-depth insights into how patients perceive their care and treatments. This approach allows researchers to explore complex issues such as patient attitudes, beliefs, and emotional responses, which cannot be measured quantitatively.

In contrast, the other options emphasize quantitative methods. Statistical analysis of large clinical trial data, as mentioned in the first option, is fundamentally about deriving conclusions from numerical data, which is not qualitative in nature. Surveys measuring blood pressure in patients focus on quantitative measurements, providing numerical data rather than exploring subjective experiences. Controlled laboratory experiments are typically structured to isolate variables and measure outcomes, again aligning with quantitative research rather than qualitative insights.

Thus, option C accurately captures the essence of qualitative research by prioritizing the subjective experiences and preferences of patients, which is central to understanding their treatment journeys in EIP.
