17) Results of reading
The reading ability of AFB was improved and considered to be acceptable and reliable as well.
Overall agreement of the reading grade was 81.1% in the first quarter of 1997 and 99.1% in the last quarter of 1998.
False (+) and false(-) were from 1.9% to 0.2% and from 2.9% to 0.7% respectively.Most of the false readings occurred at a reading of (1+) or 1-2AFB in 300 visual fields.
18) Factors for improvements
The factors identified for contributing to the improvement are: 1)standardized equipment and regular provision of reagents supply, 2)distribution of binocular microscope to all laboratories, 3)expansion and maintenance of proper size of the laboratory, and 4)frequent supervisory visits made with a strong leadership by supervisor.
19) Conclusion
"Smear Microscopy is a Core of DOTS Strategy.
20) and
DOTS will be successful with good quality of sputum smear examination since case detection and cure rate depend on the result of smear microscopy.
