Amongst the richest population data in the world.

The richness of SAIL Databank enables important questions to be comprehensively answered. We hold a wealth of population-scaled data, some of which reaches back a quarter of a century or more. We can also improve outcomes further by linking new datasets to our existing, routinely-collected data.

“I applied recently for access to the SAIL data in a study I am conducting and was expecting it to be a longwinded process if I am honest, particularly at the moment (during COVID-19). In fact, the whole thing was incredibly straightforward and quick and just a few days after submitting the required documentation my authentication token was delivered to my home. The instructions for use were also clear and easy to follow.”

“We wanted to quickly measure the effect Primary Care has on the management of Diabetes and how this affects the length of stay when these patients are admitted to hospital. The linked data and quick ethical approval meant that the work started promptly… We benefited from a specific research question and with the statistical and analytical support made available by SAIL Databank were able to quickly ascertain which factors most affected length of stay. We are looking to use the methodology to carry some similar work covering COPD.”

“Wales is a small connected country and our ability to link anonymously means we shall get even greater value out of that…that is the positive advantage of our SAIL Databank is to link up different records and what that means for the spread of Coronavirus but also the rate people are recovering.”

"When I was developing an application to use the SAIL Databank the support I received from the SAIL team was quick, efficient, knowledgeable, and also welcoming and encouraging. It's often difficult to gain access to these kinds of datasets, but the experience I had with SAIL was extremely refreshing!"
