Medication histories and current medication lists.

Dr Halamka in his blog geekdoctor.blogspot.com.
Discusses how he found both of his parents in hospital on his visit with them and had difficulty in clearly defining medication histories for them.He as a trained physician was able to do with great effort and found that in their cupboard their were medications they were not using any more and he had to separate medications for each of them.
It raised an important issue that EMR and our medical care system should help us facilitate to track the medications we are taking even when we are getting older.A better system can solve this problem.
Any body making such a system or improved system could make money and help medication errors.

P.s. These Problems will be resolved in coming years by implementing EMR and meaningful use.It is important that system may remain simple and important information sensitive.These long pamphlets given with all medicines are useless for patients simple label warnings should be the norm and Doctors and Pharmacists should be required to check for the conflicts.
