Assessment of Real World Observational Studies (ArRoWS)

An infographic promoting a new critical appraisal tool for real world evidence developed by ARC East Midlands has been released.

Real-world evidence describes evidence generated from large observational studies of routine clinical data. However, assessing it can prove challenge due to:

  • A large number of research articles are published every month that claim to produce real world evidence.
  • Many of these articles are based on specific populations and are not relevant to other clinical settings. 
  • Some of these articles make flawed conclusions because their studies are of poor methodological quality or they do not use an appropriate analysis. 

In response, ARC EM has systematically developed and tested a critical appraisal tool for real-world evidence called the ‘Assessment of Real World Observational Studies (ArRoWS)’.

This will allow researchers to quickly and easily assess the quality of real-world evidence studies using electronic health records.
