Darin Ellis sends along this radio story about a woman’s robotic heart that has a malfunction warning system that literally breaks the textbook HF rules of alarm design.  I’ll let Darin explain the unfortunate issue: This woman, who is living thanks to a robotic heart, related a story of the “heart” malfunctioning.  Apparently, although not prone to malfunction, there is [...]

I talked with an 80 year old man last weekend about how he remembers to take his medication. His solution? Put all the pills in one bottle and take out what he needs each day. It appears to be an anti-organizer. If you or your loved ones are more interested in environmental support, a new free application created by Consumer [...]

The reasons for widescale introduction of information technology into health care is that: it will reduce costs, and reduce errors. We know that in some cases it may not necessarily reduce errors.  Now we know that it doesn’t necessarily reduce costs.  Harvard researchers examined 4000 “wired” hospitals to determine the effect of widespread adoption of IT in hospitals.
