Background (1)
• Definition:
• MDR-TB is the tuberculosis which resists to Rifampicin or
Isoniazid.
• XDR is the tuberculosis which resists to
– Rifampicin or Isoniazid
– Quinolone
– At least one injectable antibiotic(kanamycin,
capreomycin or amikacin)

Background (2)
• The prevalence of all TB patients in Thailand is
130,000 cases per year, and the rate of MDR-TB
ranges from 0 to 14.1 percent of all first diagnosed TB
patients.
• The cost of treatment of MDR or XDR TB can be more
than 100 times when compare to a normal pulmonary
TB.

Background (3)
• Incidence of MDR-TB in Thailand is 2,900 cases per
year and 1,547 of them are in the first time of
treatment.
• Five percent of all MDR-TB can develop to XDR-TB in
the future.

Objectives
• To find the ways to increase potency of TB treatment
system and to decrease incidence rate of MDR-TB we
split the project into 3 parts to answer this
– the most cost-benefit method of MDR-TB screening
– System gap analysis
– Cost-utility analysis based on dynamic models on MDRTB screening.

Methods (1)
The study is conducted with two methods: Cost-benefit analysis
(CBA) and system gap analysis.
• The CBA uses the decision tree algorithm among four choices
of MDR-TB diagnosis: standard culture (L-J), Overbrooke 7H10, Microscopic observation drug susceptibility (MODS), gene
technique and the conservative technique (work up in all
failure cases.).
• The gap analysis uses an expert panel’s discussion and
inductive conclusion to formulate the policy recommendations.

Conclusions and discussion
• MDR screening is essential for all first
diagnosed TB cases because
–it can stop disease-spreading while patients are
being treated with standard drug regimen,
–decrease drug side effects.
–drug costs and patients’ expenses related to the
inappropriate drugs use.

Conclusions
• Although MODS is the most cost-benefit method
but the gap analysis shows that Thailand has many
semi-liquid culturing facilities. So it is better to use
them instead of investing more money to do MODS.

General policies(2):
5. Find sources of fund to support the system,
6. Improve the follow up care system,
7. National Health Security Office(NHSO)
should generate the ICT data system to be
used in follow up care of treatment and easy
to monitor,
8. NHSO should support the health staffs in
many roles e.g. funding source for
generating national guideline,
9. Link this treatment system to quality
accreditation to increase sustainable
