Do Piped Water and Flush Toilets Prevent Child Diarrhea in Rural Philippines

Similar to other developing countries, diarrhea in the Philippines continues to be among the top causes of child mortality and morbidity. In pursuit of its Millennium Development Goals, the Philippine government commits to reduce child deaths and provide water and sanitation services to more rural households by 2015. Applying propensity score matching on the 1993, 1998, 2003, and 2008 rounds of the National Demographic and Health Survey to estimate the average treatment effect on the treated, it is found that the incidence of diarrhea among under-5 children is lower by as much as 4.5% in households with access to piped water and 10% in those with their own flush toilets, relative to comparable households. These findings underscore the need to ensure the quality of drinking water from the pipe or from other improved sources at the point of use, and the provision of improved and own sanitation facilities.

Information, Incentives And Practice Patterns: The Case Of Tb Dots Services And Private Physicians In The Philippines

To explain divergent physician practices, studies focus on either differences in education and training or in financial incentives. The policy challenge is to identify the most cost-effective interventions to encourage adherence to practice guidelines. Utilizing private physician data in major cities in the Philippines, we show the effects of training and financial incentives in physician adoption of the TB DOTS protocol. Training seems to be more important when the new protocol is a significant departure from the old know-how, while financial incentives seem to work better on those who are already clinically competent. These imply that uniform application of information-based and incentive-based interventions may not be cost-effective.
