What should we do when we are facing absence of evidence?Created by:
Nowadays, evidence based medicine is the main principle of practising clinical medicine. The level of evidence will range from Level 1a, 1b, 1c, 2a, 2b, 2c, 3a, 3b, 4 and 5. The best evidence available will be the Level 1a evidence, which is a systemetic review and meta-analysis of multiple randomised control trials for a specific area or treatment or management. The lowest level of evidence is level 5 ,which is an expert opinion. Usually, the appropriate medical authority/body will summarize the the best available evidence, and put all togther into a guideline for some certain specific disease. But, sometime, we do face some clinical uncertainty or question, that did not have much reliable evidence out there to support our decision making, what would you do in those situation ??
