1. • Cohort Studies, Case-Control Studies: Observational studies providing evidence on risk factors, prognosis, etc.
   • Expert Consensus Documents: When higher-level evidence is lacking.
   • Key Point: Emphasis is on the quality and hierarchy of evidence.

2. Clinical Expertise: The knowledge, skills, judgment, and experience that the clinician brings to the table. This includes:

   • Understanding the patient’s unique context and situation.
   • Knowing how to interpret and apply research evidence to an individual.
   • Proficiency in performing diagnostic tests and procedures.
   • Ability to make sound clinical decisions when evidence is ambiguous or absent.

3. Patient Values, Preferences, and Circumstances: This is the crucial element of patient-centered care. It involves:

   • Understanding the patient’s personal beliefs, goals, concerns, and expectations.
   • Respecting their cultural background, social support system, and financial situation.
   • Incorporating their specific needs and desired outcomes into the decision-making process.
   • Ensuring informed consent and shared decision-making.

The EBP Process (Step-by-Step): EBP is a dynamic, cyclical process involving these key steps:

1. Formulate an Answerable Clinical Question: Often structured using the PICO framework:

   • Patient/Population/Problem: Who is the patient? What is the condition?
   • Intervention: What is the main intervention, prognostic factor, or exposure?
   • Comparison: What is the alternative intervention or control?
   • Outcome: What are the relevant results (e.g., symptoms, function, quality of life, mortality)?

2. Search Efficiently for the Best Evidence: Identify relevant databases (e.g., PubMed, CINAHL, Cochrane Library, TRIP Database) and use appropriate search strategies and filters to find the highest quality evidence relevant to the PICO question.

3. Critically Appraise the Evidence: Rigorously evaluate the evidence found for:

   • Validity: Is the study methodology sound? Are the results trustworthy? (e.g., risk of bias, confounding).
   • Importance: Are the results clinically significant? How large is the effect? (e.g., effect size, confidence intervals, number needed to treat/harm).
   • Applicability: Can the results be applied to this specific patient or this specific context? (Consider similarities/differences in population, setting, intervention).

4. Integrate Evidence with Clinical Expertise and Patient Values: Synthesize the appraised evidence with your own clinical knowledge and experience, and crucially, discuss it with the patient, incorporating their values and preferences to make a shared decision about the best course of action.

5. Evaluate the Outcome and Process: Assess the effectiveness of the decision/intervention for the patient. Did it achieve the desired outcome? Was the process efficient? Reflect on what could be improved next time. This feeds back into refining future clinical questions and searches.
