What makes the rise in TB so frustrating for physicians, Hamilton said, is that it is usually completely curable with drugs. However, the drugs must be taken every day for at least six to 12 months to eradicate the disease. Many patients, who can start feeling better within six weeks, stop taking the medications too soon. Studies have shown that if health care workers go to the patients and observe them taking their medications, compliance rates are much higher, Hamilton said. However, in rural areas, where health care workers are already in short supply, this is not a practical solution.
Trials are currently under way on a new anti-TB drug that only needs to be taken once a week.
Joining Hamilton in the project are Linda Lee, associate professor of family medicine and education specialist in the office of medical education research and development, and Margaret Wilkman, assistant clinical professor of nursing.
