MSF TB Program for Migrants in Tak

MSF TB Program for Migrants in Tak

Beginnings: MSF TB Programs in Thailand

• First MSF TB Program in Thailand started in 1985 in Karen camps (Shoklo, Maela)

• Residential TB programs with high cure rate and low default rate (AFB (+ ): cure rate = 79,5% completed rate = 5,6% ; default rate = 5,6%)

• Programs not aimed at highly mobile populations crossing the border frequently

Migrant Healthcare: Multiple Challenges

• Large unregistered population of migrants in border areas; Tak province alone with estimated 75,000 to 150,000 unregistered migrants

• Barriers to medical care:

-cost

-security concerns (deportation)

-linguistic and cultural barriers

MSF Migrant TB Program: Planning

• MSF pilot study of migrant factory workers in Maesod in 1999: undertaken with Thai public health and with MSH (Dr. Witaya)

• Census: 71 factories assessed; estimated migrant factory population of 16,000

• Random sample of 1000 workers from census: primarily young adults, 72% single, intermediate education level, only 11% speak Thai, most work >6m in same factory, basic housing conditions- overcrowding with enhanced chance of spreading communicable disease

• Not included in census: day workers, farmers

MSF TB Program for Migrants: Implementation

• MSF TB program reviewed by Thai National TB program advisors and WHO technical advisors to ensure collaboration with Thai national TB program and implementation of DOTS in Thailand; DOTS launched on a national scale in 1996

MSF TB Program for Migrants: Objectives

Target Population:

1) Factory Workers (est. 16,000)

2) Day workers (est. 10,000)

3) Farmers (rural population, difficult to access)

4) Patients crossing from Myanmar for medical care in Thailand

Target Area: Maesot, Tak province and 20 km radius; later extended to Phoe Phra

In 2003, 54 cross border patients enrolled in DOTS, 17(31%) have already defaulted during tx.

Another 10 pts did not start tx (default before tx).

Factory TB education and screening

• Factories in Mae Sot area with 20 to 2,000 migrant workers

• TB education program launched November 2002: TB transmission, symptoms, diagnosis, treatment discussed

• Offer of diagnostic sputum testing and treatment free of charge

• 37 factories visited in 2003 with approximately 6,500 workers attending sessions

Conclusions

• DOTS program for migrants has cure rates less than WHO target of 85% but given highly mobile population can be considered a success

• Keys to success:

-security issues: medications brought to migrants;

ID cards

-coordination with other groups: Thai public health, MSH,

WHO, Mae Tao Clinic, local authorities

-culturally sensitive Burmese-speaking staff

Conclusions -2

• DOTS Weak Points:

-Program requires considerable investment of staff

and resources

-High default rates for ambulatory DOTS patients

from Myanmar: cost, security concerns,

inconvenience; other strategies: education based

program, patient access on Myanmar side

-No HIV testing or education done

Conclusions -3

Factory Education: Targeted education and case finding in factories worthwhile but program is hindered by continuing problems accessing factory owners (distrust of NGOs)
