Evidence-based practice (EBP) combines research-based information, clinical expertise, and patients' values and preferences when providing care. This involves five steps:

  1. Assess the patient or problem;
  2. Ask a clinical question;
  3. Acquire resources;
  4. Appraise the literature;
  5. Apply your findings.

This guide will help you learn how to acquire and appraise research so that you can provide the best care to your patients.

Types of Research

Research studies can be broken down into two broad categories: primary research (or unfiltered information) and secondary research (or filtered information.

Primary Research refers to original studies. They can be

  • Observational
  • Experimental
  • Qualitative
  • Quantitative

Secondary Research combines many primary research studies to look for patterns. Because of that, secondary research provides stronger evidence than primary research does. This category can include

  • Meta-analyses
  • Systematic reviews
  • Editorials

Quantitative Research

Quantitative research collects and analyzes numerical data to learn about relationships between variables. Look for words like Compare, Assess, Evaluate, Measure, and Test.

Types of Quantitative Research

  • Experimental - Researcher controls independent variable and randomly assigns participants to conditions (e.g., RCTs)
  • Quasi-experimental - Researcher controls independent variable but participants are not randomized
  • Correlational - Relationship between variables with no intervention from the researcher
  • Descriptive - Describes the characteristics of phenomena that exist 
  • Meta-analysis
