Studies were undertaken in three tuberculosis clinics in Madras, a large Indian city with a good civic organization, to assess the accuracy of address recorded routinely by registry clerks at the patient's first clinic attendance. The accuracy was poor, with 20% to 30% of the letters posted not reaching the patients. It was appreciably improved, by 10% to 20% by supplementing the clerk's efforts with questioning by a motivated, experienced health visitor. An address card, a card on which the patient's address was recorded by the local postman or a literate neighbour, relative or friend, was returned by 90% to 94% of the patients, and the accuracy of addresses was found to be atleast as good as that obtained with the health visitor. Even when all three sources of information were considered, the patient's home could not be traced in 3% of cases and was found with difficulty in 4%.
