Went to the clinic

When I was insured by COVA, if I had an appointment, I waited less than 20 minutes to see my primary care physician. I would wait less than 30 minutes to see a specialist.
I arrived a few minutes early to my 2:00 p.m. appointment at the West End Crossover Clinic. I was not seen by anyone until 4:30 p.m. and I didn't see a doc until almost 5:00 p.m.
I understand that the clinic is staffed entirely by volunteer medical and clerical personnel and that there are many consumers vying for the services of this limited resource, so running on or around on time is probably not going to happen.
When I used to arrive for a 'walk-in' visit at Crossover SouthSide (and there was only ONE Crossover clinic at that time) at 8:00 a.m., I usually was not seen until around 5:00 p.m..
I experienced the same problem with MCV clinics, and one always has to have an appointment at MCV clinics.
Should people have to spend several hours or most of a day waiting simply to see a doctor, especially when they have an appointment? I was not paid for the time I had to take off work for this appointment and I suspect the other patients may have a similar circumstance with their employers.
During my last clinic visit, I was the only patient in the clinic who seemed to speak English and I suspect that most of the other patients might have been illegal immigrants. But the immigration issue and its relationship to rising health care demand and costs is another issue for another blog or commentary.
