Blood tests at surgery
My father kept being sent for blood tests at the 'Warfarin clinic' at the hospital, when the surgery does tests at the surgery. He is very elderly and so not very mobile, so getting to the hospital is logistically much more difficult and involves him needing someone to take him. The hospital told him, that if the surgery requests the test, they then must do it. Since then, armed with this information my father gets his tests at the surgery, which is much more convenient for him.
