Mike,
The system may well be very stable, but it's a right pain in the butt for a patient to use. I used to order my repeat prescriptions online until they brought in a third level of authentication which required me to do something, I forget what, but which in turn required me to supply and use a mobile 'phone. Now I do have a mobile 'phone – for my occasional use only: it spends 95% of its time switched off and quite frankly I do not see why I should be required to use it (the mobile 'phone) for their convenience.
The system required me to call up the surgery web page, dismiss the pop-up notice, select the appropriate column, select the appropriate column entry, select the appropriate word from the pop-up that appeared, input the first id, input a password, do something else, select something else, input the third id, select the pharmacy, select the drugs, and then finally logoff. 13 or so operations in total.
In contrast, I now dial up, listen (unfortunately, because I've not yet discovered how to get round it) the two or three messages including one extolling me to use the on-line system, select my preferred pharmacy by pressing a number on the keypad, speak my name, address, and the drugs required, and hang-up. Much simpler, apart from the opening messages, and much faster.
In general, I am willing to use electronic means, but when it gets as long-winded as described above, then I draw the line. It may save the surgery time, but what about my time, or doesn't that count?
So, the system may work well, it may be the bees knees etc, but until it becomes easier to use and takes less of MY time, then I will not use it.
Regards,
Peter G. Shaw
