Evidence-based practice (EBP) is the integration of

  • Clinical expertise/expert opinion
    • The knowledge, judgment, and critical reasoning acquired through your training and professional experiences
  • Evidence (external and internal)
    • The best available information gathered from the scientific literature (external evidence) and from data and observations collected on your individual client (internal evidence)
  • Client/patient/caregiver perspectives
    • The unique set of personal and cultural circumstances, values, priorities, and expectations identified by your client and their caregivers
Evidence-Based Practice Triangle

When all three components of EBP are considered together, clinicians can make informed,
evidence-based decisions and provide high-quality services reflecting the interests, values, needs,
and choices of individuals with communication disorders.

This page will teach you this versatile process so you can be confident that you're providing the best possible care no matter what clinical questions may arise.
