The cost of intensified case finding and isoniazid preventive therapy for HIV-infected patients in Battambang, Cambodia
OBJECTIVE: To measure the costs of intensified case finding (ICF) and isoniazid preventive therapy (IPT) services for HIV-infected patients in Battambang Province, Cambodia.
DESIGN: We analyzed cost data retrospectively from September 2003 to February 2006 using a microcosting or ingredients-based approach and interviewed clinic personnel to determine the cost of ICF and IPT per person.
RESULTS: Adherence to IPT at Battambang IPT clinic was high (86%) relative to other reported studies of IPT among HIV patients in developing countries. The estimated cost per TB case averted through ICF was US$363, while the estimated cost per TB case averted through IPT was US$955.
CONCLUSION: Economic evaluations of TB-HIV integrated services are necessary as countries move to establish or scale-up these services. Based upon the estimated effectiveness of ICF and IPT used by other studies examining the provision of integrated HIV-TB services, the cost per TB case prevented by ICF and IPT in Battambang, Cambodia, is less than the reported cost of treating a new smear-positive TB case.
