Impact of the RNTCPIRL-EQA-OSE visits on quality of sputum smear microscopy services of Gujarat, India.
OBJECTIVE
On-site evaluation of laboratories with standard checklist is a first step to promote effective and consistent supervision. The present study was carried out to evaluate the impact of the RNTCP- Intermediate Reference Laboratory External Quality Assessment- On-Site Evaluation visits on quality of sputum smear microscopy services of Gujarat, India. Data of three IRL-EQA-OSE visit rounds, carried out between January 2005 and December 2010 are presented here.


METHODS
Within the Revised National Tuberculosis Control Programme EQA framework, the IRL, Ahmedabad visited all Gujarat District Tuberculosis Centres, and evaluated their sputum smear microscopy services. The study covered a cohort of 29 DTCs during each of the three IRL-EQA-OSE visits. The authors focused on section III of Annexure A to study and analyse the said impact. In order to convert qualitative data into quantitative one, the authors denoted a score of 1 to "Acceptable" (No Error) remark and 0 to "Not-Acceptable" (Error) one.


RESULTS
A larger degree of improvement was noted in Standard Operating Procedure practices, Disinfection practices, and Internal Quality Control practices. Many DTCs did not retrain their laboratory staff in EQA methodology. The Gujarat DTCs achieved an overall score of (820/957) 86% during the initial OSE visits which consistently improved to (842/957) 88% and (885/957) 92% during the two follow-up OSE visits along with sustenance and improvement in many important laboratory parameters.


CONCLUSIONS
The co-sponsoring organisation (IRL) recognises the challenges and therefore, is committed to supporting state-level implementation of EQA through additional training, technical assistance to districts, and improving this technical guidance. By periodic IRL-EQA-OSE visits, sputum smear microscopy services can be sustained and improved at field level.
