Real World Access (8)

One of a series of articles about where Microsoft Office Access applications have found a real-world niche.

Karl Donaubauer's sleep research

I've created several Access applicationss for the sleep research team at the department of neurology of the University of Vienna.

They use a device called Actigraph (you wear it like a wrist watch) to collect data about the movements of patients with sleep disorders. I import the data of the actigraphs (many thousand values after several weeks), compute a bunch of evaluations, compare this objective data with subjective notes of the patients about their sleep, and data from other sources, to create movement charts etc.

The end result for the single patient is his personal sleep diary. The scientists use the apps to evalute the impact of medication, of lunar phases and many other influences. The apps are also used for comparative sleep studies all over Europe.
