Identifying risks and changing behavior protects the lives of village doctors in rural China
CHINA HAS THE SECOND HIGHEST TUBERCULOSIS (TB) BURDEN IN THE WORLD with 5.23 million TB patients; approximately 350,000 of these have multi-drug-resistant (MDR-TB). Many TB patients in China are low-income rural residents who often first seek medical care in village clinics. Thus, village doctors probably have an increased risk of TB exposure. In November 2011, US CDC in China collaborated with China CDC to assess TB infection and disease as well as TB infection control knowledge and practice among Chinese village doctors in Bayan Nur, Inner Mongolia. Located in northwestern China, Inner Mongolia has some of China’s highest rates of TB including MDR-TB. Bayan Nur is a major agricultural region in Inner Mongolia.
APPROXIMATELY 700 VILLAGE DOCTORS were surveyed. The doctors were given a tuberculin skin test and a new blood test, QuantiFERON®-TB Gold Test, which more accurately detects latent TB infection. People with latent TB infection do not have symptoms and cannot spread TB to others. Approximately 40% of the participants tested positive for latent TB infection. Chest X-rays and symptom screening identified six doctors with previously undiagnosed active TB disease, who immediately started TB treatment. Infection control training was provided after participants completed a questionnaire about work load, TB exposure, social and medical history, and TB infection control knowledge and practice.
MANY VILLAGE CLINICS DO NOT HAVE RUNNING WATER and soap for proper hand hygiene. US CDC and collaborators investigated the hand hygiene practices in such environments. As part of the TB survey some participating village doctors received alcohol-based hand sanitizer. A telephone-based questionnaire was administered to evaluate the acceptability and feasibility of using hand sanitizer for sanitizing hands among village doctors. The self-reported hand hygiene compliance was low, but acceptability of hand sanitizer was high as long as it’s provided free or at low cost. “We would like to receive more alcohol-based hand rub to use at work” stated many of the village doctors interviewed.
“THEY HAVE A BETTER UNDERSTANDING OF THE RISKS NOW and they have become aware that good infection control knowledge and practice can protect them from being infected at work. The early detection and timely treatment of village doctors who have active TB can also provide protection to their colleagues, families and friends,” said Dr. Yan Daiqin of the collaboration with his Bayan Nur Tuberculosis Dispensary.
