OutlineMilestone of survey in MyanmarObjectivesMethodResultsDiscussionLimitationProgramme implications
1972 – National TT survey
1994 – National Sputum smear positive TB prevalence survey
Protocol drafted in 2005, however, due to funding limitation, Yangon Divisional TB prevalence survey was conducted in 2006 as a pilot phase, capacity building was done and some equipment for survey were procured.

Approval of MOH - December, 2008
Ethical Approval - 16th February, 2009
Procurement started - December, 2008
Selection of Clusters - November, 2008

National TB Prevalence survey (MYANMAR)
- smear positive pulmonary TB- Culture positive pulmonary TB- symptoms suggestive of TB - radiological abnormalities suggestive of pulmonary TB

Survey sites: Country wide
Eligible pop: ≥ 15 years age group
Study period: January, 2009 to December, 2010
: Cluster sampling method stratified by
state and division.
: A cluster
Myanmar17 States & Divisions
70 clusters
7 States (28% of pop)20 clusters
7 Divisions (72% of pop)50 clusters
Remark:
For Division - Urban – 11 clusters, Rural – 39 clustersFor State - Urban – 5 clusters, Rural – 15 clusters
32 townships excluded from a sampling frame due to logistical difficulties to carry out field operations (2.5% of total populations excluded)

: 2 sputum smear positive results or 1 positivesmear result with an X-ray result consistent with active TB or 1 positive smearresult with a culture confirmation. Even scanty positive (<10/100HPF) wasconsidered as smear positive.
: 2 sputum smear results werenegative with at least 1 culture confirmation of M.tb.
: a case of smear positive or smearnegative/culture positive.
: No evidence ofbacteriologically positive TB but with strongly suggested active TB disease inthe X-ray examination were judged by the central panel consisted of at least 2chest physicians.
TB Prevalent Case
to the participants on TB symptoms and history
Compulsory with informed consent
For pregnant women, sputum specimens were took compulsory, No CXR
If CXR shows abnormal lesion or any chest symptomatics or those who gaveany history of current / previous anti-TB treatment – 2 sputum specimens weretaken
- Sputum for AFB examination at Reference Laboratories, Yangon andMandalay using fluorescence microscopy, confirmed by ZN stain
- Culture – egg based solid mediums were used
- Identification – Niacin test, PNB and Capilia test were used

National TB Prevalence Survey in ASEAN countries
(Surveys with CXR and Culture)
Limitations
Operational aspectsDelay in logistic procurement: quality of CXRSputum cups used in survey were not appropriateIn few urban clusters and remote clusters with ethnic minorities had a relatively low participation rateFewer participation in maleSome positive subjects may be missed by screening especially those with milder symptoms without detectable CXR abnormality A few positive subjects might not submit sputum samples
Design of the study• TB in children and EP could not be assessed• HIV, MDR-TB data are not available
LimitationsOperational aspects
Cross contamination in the laboratory in MandalayLanguage barrieer
Analysis• Removing possible TB cases : one S+ or one culture positive without other evidence of disease from the survey case list without imputation of missing value may lead to an underestimation of the prevalence by around 10-15%.

and that the re is no smear posit ive case in Ch ildren
Quality survey confirmed the high prevalence of TB
Only 1/3 of S+ reported cough >3 weeks
35% decline of S+TB with Chronic cough compared with 1994 survey
It seems that DOTS has worked in the target group (S+ with chronic cough)
However, no-decline was observed in younger age groups: Migration and HIV?
Summary
Urban-Rural discrepancies (R>U in 1994 )
Urban areas are having high prevalence cases than rural in current survey
Male-Female differences
State had higher prevalence than Division
Visiting medical facilities as first action for chronic cough is not common.Difference between urban and rural is large. Lower proportion of people visit medical facilities in rural areas: Mainly access problem?
Summary cont…
Implication for the programme Higher prevalence in States with fewer notification suggests challenge in access
High prevalence in urban with high notification rate suggests higher burden of TB in urban, congestive areas
"Gap between prevalence and notification" and "recent decline of notification rate" suggest a slow decline of TB incidence and limitations of current case finding strategy
Removing serious cases from community, impact on TB mortality might be significant. However, the impact of control efforts on TB incidence might not be sufficient
Most TB symptomatics have not received appropriate TB screening and diagnosisLimitation of access even in urban areasLimitation of the screening criteria by symptomsLimitation of smear microscopy diagnosis Limitation of CXR diagnosis in routine practice (Are smear negative cases really TB? Under-diagnosis as healed TB?)
Speculations

Possible spread of 2nd epidemic wave from Urban to Rural
Low prevalent clusters: the 2nd wave not reached yet

AcknowledgementNTP Myanmar appreciates to multiple partners (MOH/DOH, WHO, JICA/RIT, PSI, USAID, 3DF, MHAA) involved in this survey contributing either technical or financial support for the making the survey successful.The support of local health authorities and basic health staff, local volunteers, local communities was also a great value in data collection phase.Special thanks to Dr. Hans, H. Kluge, WHO, Dr. Ikushi Onozaki, WHO and Dr. Norio Yamada, RIT were recorded for their tremendous contributions.

Discuss to plan next survey to measure changes after 2015
With strong leadership and partnership, Myanmar will be able to show the impact of new interventions and strategy.A quality survey was carried out to provide the base line data and scientific evidencesQuality of routine surveillance is essential to follow the future change

Prevalence Estimates were done with deferent methodologiesMost have similar resultsConsidering the participations by age and sex, estimate changes 1-2%Some scenarios with counting those with missing value may increase the prevalence around 10% However Central Review and CXR QA reading suggest that those who missed examinations are less likely to be positive than those who submitted, few major error in screening reading was observed by audit.
ex. No symptomatic subject with TB suggestive CXR was missed
