Use of a standardised checklist to assess peripheral sputum smear microscopy laboratories for tuberculosis diagnosis in Uganda.
METHODS
TB diagnostic units in Uganda.


OBJECTIVE
To assess and improve the supervision and performance of sputum smear microscopy in the peripheral diagnostic units in Uganda using a standardised laboratory checklist.


METHODS
A standardised checklist was developed and used during the quarterly supervisory visits of the District TB and Leprosy Supervisors for five quarters from the fourth quarter of 1997 until the last quarter of 1998. Individual peripheral laboratory performance was monitored during the study period.


RESULTS
Forty-eight of 304 TB diagnostic units in six of the 45 Ugandan Districts were supervised using the checklist. A total of 208 checklists were analysed. The situational analysis of the peripheral diagnostic units at the beginning and at the end of the study showed a marked improvement in laboratory performance in all aspects related to sputum smear microscopy. Individual laboratory performance was monitored over five quarters, and timely response to shortcomings was provided.


CONCLUSIONS
The systematic use of a standardised laboratory checklist can be considered an important step forward in improving the performance of the peripheral laboratories in Uganda through on-the-spot correction of any identified shortcomings.
