If you think that Biometrics has something to do with numbers then you would be correct, but there is so much more to it than that.

Biometrics is the combined expertise from different job disciplines to help power study design, and furthermore understand the results from it.

Biometrics departments have in the last few years been split up into individual specialisms including activities such as clinical data management, medical dictionary coding, biostatistics and SAS programming. Here is a brief overview of the main areas:

Clinical Data Management

Data Managers are responsible for making sure that the data collected in a trial is accurate and complete. The role has changed over the years and what was once data entry and checking has now become much more project management focussed, often coordinating teams of data managers across continents and time zones requiring not only a great eye for detail but also strong communication skills and ability to meet deadlines.

SAS Programming

SAS programmers will provide statistical programming support for the statisticians and statistical programming expertise for the company. They will write programs to create statistical tables, listings, and graphs and will often work closely with both Clinical Data Managers and Biostatisticians.


Biostatisticians will apply statistical assessment tools to help plan clinical trials, providing valuable input into study design such as sample size and data collection methodology as well as final and on-going analysis to help identify if a study has been statistically proven. Biostatisticians can also get involved in the analysis of efficacy and safety data.
