Yes, with so many corporations owning stakes in different aspects of the healthcare business - hardware, insurance, pharmaceuticals - it seems inevitable that they will be trying to push doctors into overprescribing their drugs via big data.

It occurred to me when my doctor said my blood pressure seemed high, and I needed to monitor it for a week. The results said 'too high -prescribe an antihypertensive'. But what if the machine was deliberately programmed to exaggerate?

They did tests at the hospital as well - but the trend now is to use remote monitoring to save money, which means calibration and reliability are entirely in the hands of the manufacturer.
