Problems in the management of medical waste in Thailand.

OBJECTIVES: To identify problems in the management of medical waste in Thailand for future development. MATERIAL AND METHOD: The study was done in 39 hospitals during June and July 2002 by interviewing medical personnel on knowledge and attitude in management of medical waste, observation of practice and checking the amount of medical waste in waste bags. Certain laboratory investigations were done in dustmen. RESULTS: The amount of medical waste was 0.41 kilogram per bed per day. Problems identified were inadequate knowledge in management, improper practices, high incidence of sharp injury at work. Laboratory tests in dustmen showed evidence of pulmonary tuberculosis in 3.4%, parasites and intestinal pathogens in stools 5.1% and positive for HBsAg in 8.5%. CONCLUSION: Improper management of medical waste was present in all hospitals. Risks of exposure and incidence of infection related to the management were at concerned levels. Education and practice guidelines are needed.
