    ABSTRACT: Revised National TB Control Programme (RNTCP) in India recommends that all previously-treated TB (PT) patients are offered drug susceptibility testing (DST) at diagnosis, using rapid diagnostics and screened out for rifampicin resistance before being treated with standardized, eight-month, retreatment regimen. This is intended to improve the early diagnosis of rifampicin resistance and its appropriate management and improve the treatment outcomes among the rest of the patients. In this state-wide study from Gujarat, India, we assess proportion of PT patients underwent rapid DST at diagnosis and the impact of this intervention on their treatment outcomes.

    ABSTRACT: Setting: The national hospital and stroke rehabilitation services of the Fiji Ministry of Health. Objective: To describe patients admitted with stroke to the Fiji Colonial War Memorial Hospital (CWMH) from January 2010 to December 2012, and to report on rehabilitation services accessed during and after admission. Design: Retrospective descriptive study using patient records. Result: Of the 328 patients admitted with stroke, 54% were male, 55% i-Taukei and 16% aged ?50 years; 75% had hypertension, 41% diabetes and 37% both; 23% (n = 76) died. Of the survivors, 58% (146) received rehabilitation therapy during admission at the CWMH. After discharge, 10% (n = 26) received therapy at the National Rehabilitation Hospital; six accessed the services of the community rehabilitation assistants. Just over half of stroke survivors (52%) remained in CWMH for

    ABSTRACT: 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. 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. 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. 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.

    ABSTRACT: To assess the proficiency of Senior TB Laboratory Supervisors (STLSs) and district level Laboratory Technicians (LTs) in sputum smear microscopy. Intermediate Reference Laboratory (IRL), Ahmedabad had manufactured and validated Proficiency Panel Testing slides from sputum samples, made On Site Evaluation (OSE) visits of District TB Centres (DTCs) in two rounds, and conducted Proficiency Panel Testing of STLSs & DTC-LTs from January 2005 to June 2009. High level of concordance in Z-N smear grading was found between Microbiologist and district laboratory staff. DTC readers reported overall consistency level of more than 98% in Z-N grade agreement during both the IRL, EQA, OSE visits. The tendency to over-grade the panel slides was much higher (more than 22%) as compared to under-grade (less than 2%) them in "correct slides". High False Positive (HFP) error was not observed in the present study. Laboratory supervisor's proficiency can be quickly assessed by Proficiency Panel Testing, under multi-level quality assurance network system of sputum smear microscopy in public health programmes like the RNTCP. Proficiency Panel Testing is highly replicable and reproducible tool for quick and reliable assessment of proficiency of the staff and it can be made more effective by raising the proportion of lower grade positive slides in panel set of each reader. DTC readers' overall agreement level of more than 98% in Z-N grade suggests high level of precision and excellent consistency during both the IRL, EQA, OSE rounds. It is concluded that even for a large network of sputum smear microscopy centres under public health programmes like the RNTCP in order to take corrective action, Proficiency Panel Testing can be effectively used for quick identification of suboptimal- technical performance of the supervisory staff.
