Data protection is the biggest hinderance in my opinion.
I attended a future technology exhibition at SRFT and I was really impressed with one idea. I spoke to the people behind it at length, with me being a technophobe I wondered how easy there idea would be for me to use. The majority of people only interact with one department, some though with co-morbidities such as myself interact with several. The idea they were working on was an app for your phone that held your medical records. It may not be practical at the moment but at some time in the future everyone will have a mobile phone/device and it would negate the need for a huge infrastructure for medical records. Now bear in mind I am a technophobe but as I understood it everyones records could be kept in one of these cloud things and the app could be used to keep your details updated and instantly transferable between departments. Blood results, test results, clinical outcomes would all be on the app. Nowadays we trust apps to do our banking so why not at some point trust them with our health records. They are doing a small trial as far as I know with people who have diabetes, they can upload daily results which alerts there doctors to any changes.
The app if it is developed and becomes available makes perfect sense for me, I visit numerous departments who at the moment use a paper trail to keep each other informed of where I am at. Of course there will be glitches in a paper trial and I have just had a glitch in my care, but because I am educated in how the system works I navigated it easily and the issue was quickly addressed. For people unsure of how the system works an app could well be a brilliant solution.
As for departments not working well together I get that, some departments do work very well due to close proximity of symptons.For instance, Dermatology and Rheumatology work very closely, Neurology stands apart. Generally I have had no issues that have affected me personally but again it is because I know the system and more importantly have a great relationship with my Prof despite him being a Liverpool fan
