The Joanna Briggs Institute (JBI) has as its central focus the effectiveness, appropriateness, meaningfulness and feasibility of health practices and delivery methods. Any indication that a practice is effective,expertise,inference,deduction or the results of rigorous inquiry is regarded as a form of evidence by the Institute. The JBI regards the results of well designed research studies grounded in any methodological position as providing more credible evidence that anecdotes or personal opinion;however,when no research evidence exists, expert opinion can be seen to represent the ”best available” evidence.
