Bazian is a firm that specialises in evidence-based analysis of drugs, devices and healthcare services to determine what works and what doesn’t. Bazian was founded in 1999 by two clinicians at the British Medical Journal. It has supplied of high-quality evidence-based content to Clinical Evidence, Elsevier Science and The Map of Medicine and others.

Bazian has supplied rapid systematic reviews to various groups within the NHS and supplies the critical appraisal analyses that underpin the 'Behind the headlines' daily news analysis service on NHS Choices. 

The problems Bazian helps to solve

Insurers, health providers, governments, clinicians and patients routinely have to choose between competing and costly clinical options. Decisions are often made from a position of uncertainty caused by:

  • the growth in the amount of available information, with thousands of studies for every healthcare issue, 
  • the different opinions on offer because individual studies usually reach different conclusions, and 
    the fact that clinical information is constantly changing as more research is conducted.

Bazian helps eliminate uncertainty and bias by providing independent, thorough and scientifically robust assessments of drugs, devices and services. This allows people making clinical decisions and purchases to be confident their decisions are grounded in a detailed understanding of what works best and what provides best value for money at any given time. 

The Bazian name

Bazian (pronounced Bays-ee-an) takes its name from the Reverend Thomas Bayes, a vicar in Tunbridge Wells in the 1700s. Like many groundbreaking theoreticians of risk, he liked to gamble and developed his theory of conditional probability to increase his winnings at the track.

Bayesian theories are widely used in the modern world – from Google searches to stock trading – as well as in key parts of evidence-based practice.
