The National Tuberculosis Prevalence Survey done in 1997 (1997 NPS) revealed that the magnitude of tuberculosis in the Philippines hardly declined between 1982 and 1997. In 1996, the National TB Control Program (NTP) adopted the directly observed treatment short-course (DOTS) strategy. By the end of 2001, more than 90% of the population have access to it. Cohort analysis revealed good treatment outcomes. Despite this improvement in the public sector, there is a concern that the epidemiological impact of DOTS will be limited due to the non-participation of the private practitioners, a major stakeholder. Public-private sector collaboration in TB control was strengthened since the Philippine Coalition Against TB (PhilCAT) was organized in 1994. There are four areas of collaboration, namely, policy development, advocacy and information dissemination, training and research and service delivery. Four models of public-private mix (PPM) DOTS in service delivery were developed. The private DOTS clinics provide the space, staff and operational funds while the Department of Health (DOH) provided technical assistance, anti-TB drugs, laboratory supplies and forms. Evaluation showed that PPM in TB control is feasible with good results. The major challenge is to replicate and institutionalize the PPM DOTS.
