I dont know how to say this, But here go's, Some times its a shared responsibly, Between the Doc-Patient and mostly the family of the patient..The Doctor sees hundreds of patients so sometimes he can't see the forrest from the trees, The patient most times doesn't know whats going on, So thats where the Family comes in to oversee things..
As far as the pharmacist is concerned 'If he can't read the handwriting he can't fill the prescription, And rightfully so.. You have to have the doctor fax or E-mail the order to the pharmacist..And that all can be done over the phone...My Wife worked in a large nursing home' Medical Records and that was common...
