My father is 93 years old and lives in an assisted care facility. His mind is still very sharp but his body is failing him. He has had diabetes for 20 years and is treated with insulin shots 3 times a day. He also has a very bad knee which makes it hard for him to walk, so he uses a walker. He wants knee replacement surgery, but no doctor will operate on him at that age, especially with his health conditions (he also takes heart medication). My question is how often do we (his adult children) take him to the doctor? every time he has a scheduled doctor's appointment, they check his blood work and nothing has changed, so they send him home with another scheduled doctor's appointment in 3-6 months. Is this necessary? It seems to me that he would be fine in having annual doctor's appointments rather than appointments every 3-6 months.
I only take my mom to her primary care physician when she's having issues. Your dad's insulin is a bit trickier, but it sounds like he's stable. Does he check his own sugar, or does someone do that for him on a daily basis? If not, get a meter and check it yourselves.
