As airlines become better at updating passengers when flights are delayed, I wonder, briefly, whether this will ever come to the operating theatre. Rather than waiting a couple extra hours at the airport, I was able to get some errands done and arrive at a reasonable time before the delayed flight departed. So many patients, especially at the end of the day, wait around because their room has been delayed. Wouldn't it be ideal if there was some automated system that could let patients know that they could have a sip of water or come in a little later if their case might be delayed?
