Medical Care in Tanzania--How does this East African republic take care of its people?

I just got back from Tanzania, where I supervised 7 medical students who were doing a couple of really awesome ultrasound projects in Mwanza, the second largest city in this East African country. I will write about the projects in a different blog. Mwanza is right on the shores of Lake Victoria, a huge but relatively shallow body of water which Tanzania shares with Kenya and Uganda. Tanzanians are friendly, and the weather in Mwanza was perfect. We were at the tail end of the rainy season, but saw almost no rain, and the temperature was perfect, in the mid 80s during the day and cooling off at night. Because of the lake, there are huge numbers of birds, egrets, cormorants, storks, kingfishers, brightly colored starlings, and lots of frogs who became vocal at night. Tourists do not come to Mwanza, probably because there are more jaw-droppingly amazing places nearby, including Mt. Kilimanjaro, the island of Zanzibar and the Serengeti. People speak English and Swahili, but mostly Swahili, which makes getting along a little complex. We had wonderful hosts who helped with the language issues, and we all picked up a working knowledge of Swahili, mainly stuff like "hello" and "thank you" and "your liver is fine."

Our projects involved visiting several hospitals in Mwanza and talking to many healthcare professionals. I was able to go on ward rounds with some of the doctors we met and wandered around one afternoon in the very large public hospital, Bugando Medical Center, which has a medical school and is loosely affiliated with Cornell. There were many hospitals, of varying sizes and capabilities. There were district health centers which were publicly funded and provided care to outpatients and had wards for patients who were too sick to return home.  There were dispensaries, which despite their title, did not just act as pharmacies, but also offered clinic services such as doctor appointments, birth control, prenatal care and HIV monitoring. There were also private hospitals which were a little less crowded than the public ones, a little more cushy and required that the patient pay for their own care completely, except in rare cases such as having health insurance (usually only government employees) or having any of the conditions which the government pays for in full. Doctor visits were both by appointment and drop-in, and there was 24 hour availability of doctor care, though doctors were pretty scarce on nights and weekends. The big hospital, Bugando, had a cafeteria and would serve food to the patients, but that was a rarity, and generally families were expected to bring the patient food and drinks.

In the private hospital the rooms were semi-private, 2 beds to a room, 1 person per bed, with a mosquito net. In the public hospitals the wards were open, with 10 or more beds per room, and no curtains between patients. Some had mosquito nets, some didn't.  Usual necessities in US hospitals, things like blood pressure cuffs, oxygen and suction, which are attached to the wall, were absent. Most facilities had the ability to do a chest x-ray, some could do an ultrasound, but usually just for female problems and obstetrics. There were very few CT scanners and no MRI in the city. Basic surgery was available, but more complex issues had to go to the largest city in Tanzania, Dar Es Salaam, which was over an hour away by airplane and 10 hours away by car or bus. The nicest hospital room I saw was a cement floored 2 bed room that was about 200 square feet with a window, a door, mosquito net, bedside table, sheets and an ancient plastic covered pillow.  It wasn't dirty, but neither was it scrupulously clean. There was no electrical outlet or fan, though the temperature was comfortable.

The physicians I saw interact with patients were mostly polite, but clearly didn't spend much time either in examining the patients or taking a history, and it was rare to find any evidence that full vital signs were taken after the patient was admitted, though abnormal ones, such as blood pressure and temperature, were repeated at least daily. Almost everyone got a blood smear for malaria, a urine test, a stool examination for worms and sometimes an antibody screen for typhoid, which was often false positive. Chemistry testing was only rarely done, and not always available, and blood counts were available but not often used. HIV testing was available, and most hospitals had the ability to test CD4 counts to evaluate patients with known HIV.

Prenatal care is available to patients free of charge, as is birth control. Patients are tested for HIV when they first present for prenatal care and receive peripartum prophylaxis to prevent vertical transmission. Vaccination for measles, mumps, rubella, polio, BCG for tuberculosis, hepatitis B, diptheria, pertussis and tetanus are all available and encouraged. There were always lines of mothers with babies at the health centers we visited, there for vaccination. There is no cost to the patient for care for children under 5, pregnant women, patients over the age of 60 and patients with HIV/AIDS or tuberculosis. Women are required to receive prenatal care and deliver their babies at hospitals, though this is far from universal in practice. Since there is very little access to blood tests or ultrasound, it appears that the primary purpose of prenatal care is to identify patients who are clearly at high risk of birth complications and to treat and prevent the spread of HIV.

Sick patients who presented to a hospital would not be denied care, even if they had no money to pay for it, though if they arrived less than dangerously ill, they would be expected to pay for care if they did not fall into a group for whom care was free. Often, regardless of symptoms, patients were treated for one of the top ten diagnoses, based on the few lab tests that were done, and sometimes were treated based on the most common diagnosis associated with their primary complaint, without confirming lab tests, imaging or examination findings. The top ten diagnoses were malaria, typhoid, ascariasis, urinary tract infection, sickle cell disease, pneumonia, pelvic inflammatory disease, HIV, infectious diarrhea and diabetes. I also saw patients who had been identified with hypertension and renal failure (one 90 year old patient), cirrhosis and hepatoma (a young woman who probably had congenital hepatitis B), measles (an unvaccinated baby) and severe iron deficiency anemia. It is interesting that in the fast food stalls they sell little sticks of clay for pregnant ladies to eat. Eating clay (and laundry starch and dirt) is called pica, and is strongly associated with iron deficiency in pregnancy. I do wonder if there may be a significant under recognized prevalence of iron deficiency in pregnancy.

Malaria appeared to be the most common diagnosis in the patients who were hospitalized, and also was a pretty common diagnosis in the outpatients. A thick blood smear was examined in most of the patients who presented with any one of a number of vague complaints, including headache, weakness and low grade fevers. If parasites were seen, they were treated with appropriate medications, but many people in Tanzania harbor malaria parasites and are not sick with malaria and probably don't require treatment. I'm not sure if the inpatients getting their intravenous quinine actually were suffering from malaria, though I'm sure at least some of them were.

IV fluids are generally available as are appropriate drugs for HIV, malaria and serious infections. There is very little choice in medications for hypertension and even a patient with lethargy due to extremely high blood sugars did not warrant an insulin drip since there was no accurate way to deliver it. I saw one older woman whose blood pressure was 250/120 who had run out of her medications because they weren't available at the health center due to government shortages. She was sent to a pharmacy with a prescription which she may or may not have been able to afford to fill. HIV medications and some of the expenses for the health care centers which provide both the meds and HIV testing are funded by the United States Agency for International development (USAID.) This organization also helps fund maternal and child health and tuberculosis treatment, which has improved numbers like prevalence of HIV and death rates. USAID also is involved in promoting use of condoms for prevention of HIV, which is unfortunately not terribly effective in Tanzania. Birth control with pills or the intrauterine device (IUD) are enthusiastically accepted, but in the clinics I visited I heard that condoms were not very popular, and outside of clinics were rather expensive.There has been a huge increase in the number of people being tested for HIV, which may decrease spread of the disease, and treatment will also reduce transmission.

Tanzania has the lowest ratio of doctors to patients in the world, which may be due to a large refugee population since it is one of the most stable countries politically in East Africa. In Tanzania a person can be called doctor if he or she has completed any of 3 different medical education programs. After 3 years of medical education, after the equivalent of high school graduation, a person can become a clinical officer and can provide medical care in a clinic with some supervision. After 3 more years that person can become an assistant medical officer, with more autonomy. The MD program is a full 5 years, and includes an internship year. If a person starts with a clinical officer degree, he or she can work as a doctor while finishing an MD degree. The education being offered to clinical officers appeared to me to be pretty rigorous, including anatomy and physiology as well as practical skills that would be part of the work of a hospital nurse in the US. My Pocket World in Figures put out by the Economist magazine says that Tanzania has 145,667 patients for each doctor, but it is unclear if they include clinical officers and assistant medical officers in this count. It has a prevalence of HIV/AIDS of 5.6% in people between the ages of 15 and 49, 12th in the world, but far better than Botswana in which 25% of this population is infected. There is very little smoking and drug abuse is uncommon, though there are alcoholics. There is no concept of drug treatment programs or even mental health care. Pain is treated only with acetaminophen or oral or parenteral nonsteroidal anti-inflammatory drugs. There are no opiate pain medications in the hospitals I visited, even though physicians recognize that these would be merciful in many circumstances.

I am very impressed by the level of basic medical care provided in Tanzania, and people do have a kind of safety net should they become very ill or injured. Many of the big-ticket, costly items of medical care are heavily subsidized by the US which pretty much bypasses the government, assuring ongoing care of high risk individuals even when government budgets get tight. Still, Americans would definitely rank their own health care system far above Tanzania's. Availability of technology such as imaging and blood tests is vital to making correct diagnoses, given the huge variety of treatments we have to offer in the US, and we have come to expect at least some level of a doctor/patient partnership in making decisions about our health care. Americans expect basic comforts, including appropriate and individualized diets as well as clean and comfortable beds and rooms, which are not at all basic in Africa.

Very interesting article. It's sad to hear that medicine is a luxury in Tanzania, while it's an expectation in the U.S. We not only need to lower the cost of medicine, but we also need to get medicine to places like Tanzania quickly. Access to basic health care should not be a privilege. Check out this Facebook page. It's pretty interesting and takes a more science-bases approach to solving some of these critical problems.
