assigned to the experimental or controlled group. Both Researchers and subjects are blind to the intervention. Allows the user of the research to have more confidence of the research in the evidence that was created by that research. Qualitative research is research that answers questions that cannot be answered in a quantitative study design. Focuses on a person’s experience and uses analysis of data such as interviews, surveys, or questionnaires. Examples of qualitative method studies are ethnography, phonography, grounded theory and case reports. Mixed design reports uses both qualitative and quantitative approaches. A good example for the need for this is a new medication. Qualitative – How the drug works. Qualitative – How the patient feels while taking the drug. Evidence summaries are short, easy to read documents that summarize scientific evidence from high quality professional databases, systematic reviews and metanalysis. Systematic reviews are summaries from controlled trials that provide a high level of evidence on the effectiveness of healthcare interventions. Metanalysis is a research process that systematically merges single independent studies using statistical data to calculate an overall effect. Practice guidelines are a systematically developed statement that assist the practitioner in decision making about appropriate healthcare for specific clinical circumstances. Attributes MAJOR o Replicability – Findings are verified when they are repeated in other studies. o Reliability – Findings most be consistently and accurately measured. o Validity – Accuracy of the application in it’s findings. Successfully measure what it is intended to measure. o Individualized care MINOR o Publicly Available – People have to be able to find it. o Understandable – If it is too complex no one will be able to interpret. o Usable
Nurses job to educate patient and give them all the options. It is the patient’s job to make the decisions. Values may not fall in line with what evidence shows, but it’s patient’s decisions. Nurse should use best available evidence to guide practice decisions.
