A few years ago, I was taking care of a woman who was a victim of violence. I wanted her to be seen in a clinic that specialized in trauma survivors. I made the appointment myself because, being the director of the department, I knew if I did it, she would get an appointment right away. The clinic was about an hour and a half away from where she lived, but she took down the address and agreed to go. Unfortunately, she didn't make it to the clinic. When I spoke to the psychiatrist, he explained to me that trauma survivors are often resistant to dealing with the difficult issues that they face, and often miss appointments. For this reason, they don't generally allow the doctors to make appointments for the patients. They had made a special exception for me. When I spoke to my patient, she had a much simpler and less Freudian explanation of why she didn't go to that appointment: her ride didn't show. Now, some of you may be thinking, "Didn't she have some other way of getting to that clinic appointment?" Couldn't she have taken an Uber or called another friend? If you're thinking that, it's probably because you have resources. But she didn't have enough money for an Uber, she didn't have another friend to call. But she did have me, and I was able to get her another appointment, which she kept without difficulty. She wasn't resistant, it's just her ride didn't show. I wish I could say that this was an isolated incident, but I know from running the safety net systems in San Francisco, Los Angeles, and now New York City, that health care is built on a middle class model that often doesn't meet the needs of low-income patients. That's one of the reasons why it's been so difficult for us to close the disparity in health care that exists along economy lines despite the expansion of health insurance under the ACA, or ObamaCare. Health care in the United States assumes that, besides getting across the large land expanse of Los Angeles, it also assumes that you can take off from work in the middle of the day to get care. One of the patients who came to my East Los Angeles clinic on a Thursday afternoon presented with partial blindness in both eyes. Very concerned, I said to him, "When did this develop?" He said, "Sunday." I said, "Sunday? Did you think of coming sooner to clinic?" And he said, "Well, I have to work in order to pay the rent." A second patient to that same clinic, a trucker, drove three days with a raging infection, only coming to see me after he had delivered his merchandise. Both patients' care was jeopardized by their delays in seeking care. Health care in the United States assumes that you speak English or can bring someone with you who can. In San Francisco, I took care of a patient on the inpatient service who was from West Africa and spoke a dialect so unusual that we could only find one translator on the telephonic line who could understand him, and that translator only worked one afternoon a week. Unfortunately, my patient needed translation services every day. Health care in the United States assumes that you are literate. I learned that a patient of mine who spoke English without accent was illiterate when he asked me to please sign a social security disability form for him right away. The form need to go to the office that same day, and I wasn't in clinic, so trying to help him out, knowing that he was the sole caretaker of his son, I said, "Well, bring the form to my administrative office. I'll sign it and I'll fax it in for you." He took the two buses to my office, dropped off the form, went back home to take care of his son, I got to the office, and what did I find next to the big "X" on the form? The word "applicant." He needed to sign the form. And so now I had to have him take the two buses back to the office and sign the form so that we could then fax it in for him. It completely changed how I took care of him. I made sure that I always went over instructions verbally with him. It also made me think about all of the patients who receive reams and reams of paper spit out by our modern electronic health record systems explaining their diagnoses and their treatments, and wondering how many people actually can understand what's on those pieces of paper. Health care in the United States assumes that you have a working telephone and an accurate address. The proliferation of inexpensive cell phones has actually helped quite a lot, but still my patients run out of minutes and their phones get disconnected. Low income people often have to move around a lot by necessity. I remember reviewing a chart of a woman with an abnormality on her mammogram. That chart assiduously documents that three letters were sent to her home asking her to please come in for followup. Of course, if the address isn't accurate, it doesn't much matter how many letters you send to that same address. Health care in the United States assumes that you have a steady supply of food. This is particularly an issue for diabetics. We give them medications that lower their blood sugar. On days when they don't have enough food, it puts them at risk for a life-threatening side effect of hypoglycemia, or low blood sugar. Health care in the United States assumes that you have a home with a refrigerator for your insulin, a bathroom where you can wash up, a bed where you can sleep without worrying about violence while you are resting. But what if you don't have that? What if you live on the streets, you live under the freeway, you live in a congregant shelter where every morning you have to leave at 7 or 8 am? Where do you store your medicines? Where do you use the bathroom? How do you put your legs up if you have congestive heart failure? Is it any wonder that providing people with health insurance who are homeless does not erase the huge disparity between the homeless and the housed?
