Under the District Tuberculosis Programme, the key personnel at the District Tuberculosis Centre are expected to supervise the Peripheral Health Institutions (PHIs) periodically in order to assess and improve the programme activities. A supervision form is used for the purpose of recording the observations made during supervisory visits. This procedure is subjective and does not offer an objective assessment. In this paper, an objective scoring method has been described for supervision of PHI laboratories. The total score suggested is 200 which is apportioned as follows: cleanliness-15, registration & recording-35, sputum collection-10, smear preparation-30, staining-35, microscopy-35, and maintenance of microscope-40. Each category in turn is subdivided according to specific task performed. Minimum satisfactory score is 75% for each topic individually. High level of efficiency is thus recommended, as microscopy is the mainstay in casefinding of tuberculosis. A similar scoring procedure can also be used at the State TB Centre for the purpose of supervising the DTCs. However, this is only a quality control procedure and does not reflect the quantum of work.
