For more than a decade healthcare practitioners have been discussing the
merits of evidence-based medicine. But what is evidence? Most use this
term to mean the best available research evidence? And when one wants to
know how well a particular diagnostic, therapeutic or preventive
intervention works, the preferred type of research is using randomised
controlled trails (RCTs). The Canadian task force on preventive health
care, which formally introduced the concept of “levels of evidence”, has
assigned RCTs the highest level of evidence.

- EVIDENCE-BASED MEDICINE IN EYE CARE – RELEVANT RESEARCH TO INFORM PRACTICE
Evidence-based medicine aims to help clinicians and practitioners with
information on how to care for their patients by making use of the best
evidence available. This evidence invariably derived from deliberations

literature. “Hunches” or “gut feelings” or “expert opinions” have had an
informal burial with the birth of the more formal evidence based
medicine, which now influences clinical decision-making and practice.

to the development of the Cochrane Library database of systematic
reviews, the establishment of the UK.
