Directly observed therapy for tuberculosis

摘要

An American advertisement for engine oil filters says, "You can pay me now or you can pay me later!" This challenge might do equally well for directly observed therapy for tuberculosis. With the oil filter, buyers are weighing the cost of routine preventive oil filtering against the cost of eventually overhauling the engine because of lack of maintenance. With tuberculosis, the balance is between the costs of routine monitoring to ensure that treatment is completed versus the enormous expense of poor adherence, treatment failure, recurrent hospitalisation, drug resistance, and continuing transmission of infection.
