The disadvantage here is the patient’s privacy as this will be given away by the technology. Is it necessary to bring on board bio medics into the patient doctor confidential agreement? A kind of agreement is signed by the patient but it does not stop the patient being watched by a third party.
The challenge is that some patient’s will readily go against this due to privacy challenge, secondly patients might begin to miss time of visits to their physician since they believe they are already being monitored.
Another big one is the question of the data banks for all these information. The new age which makes it possible for big companies to get hacked, safety of the patient’s privacy is termed as relatively low.
