Whether you need physical therapy, dialysis or other regular doctor’s appointments for some reason, medical transportation can be the answer you need for getting the best possible health outcome. Among other things, it can protect you from having to drive while medicated or otherwise in a vulnerable state. People who drive while medicated or following certain kinds of medical treatment can be at increased risk of having an accident.
Maybe you have been paying a relative or your maid to drive you to these appointments. Maybe you felt that was a better solution than driving yourself, calling a cab or taking public transit. Maybe it is a better solution than those options. But, is it really the best solution available? Is your relative reliable? How clean is their vehicle? How annoying do you find them?
There is another solution available. That solution is private medical transportation. It will be clean. It will be staffed by trained professionals qualified to assist you with any minor complications that arise en route. It will be a better answer than the bus, a cab, or driving yourself. If you have any concerns about a friend or relatives driving you, for some people, it can be a superior solution to those options. Some people just do not have anyone close to them that they can really rely upon.
If you are getting on-going treatment, like physical therapy or dialysis, you should not underestimate the seriousness of your treatment. When you do something regularly, it is easy to get into a mindset that it is an ordinary event, like going to the grocery store, because it seems so normal and routine for you. Dialysis for kidney disorders is not at all an ordinary event.
Stop and think about the kind of medical care you are getting on an on-going basis and the significance of the condition it is treating. Think about the worst case scenarios. How bad can it be if something goes wrong? Then, think about all the things that can go wrong if you drive yourself home, take public transit or even just call a friend or family member who has no medical training. 
If you get into some kind of trouble, will your driver know what to do? Do they know anything about the condition for which you are being treated? Do they even know what condition you have? Or are they just being hired to drive?
If you get confused or pass out or otherwise find yourself in a situation where you need assistance and cannot communicate to tell people what your condition is, what your appointment was for, the kind of treatment you are getting and so on, what happens if an ambulance shows up? What happens if your driver does not realize your confusion is possibly indicative of a serious medical issue and simply chalks it up to your age or personal quirks?
If you are getting on-going care, your underlying condition is probably medically significant. Private medical transportation can be a good investment to protect you against the possibility of minor complications turning into major problems. One major health event involving in-patient hospital care is far more expensive than medical transportation, even regular transportation.
