The design and implementation of the PartoPen maternal health monitoring system

The World Health Organization advocates the paper partograph as the single most effective tool for monitoring labor and reducing labor complications in developing countries. Used correctly, the partograph can serve as a tool for early detection of serious maternal and fetal complications during labor, allowing sufficient time for an appropriate response. However, in order to be effective, the partograph must be used correctly. Recent studies in Kenya reported that less than one fourth of partographs were completed in accordance with WHO guidelines. In developing countries, lack of training and continuing education, exacerbated by limited resources, represents a serious barrier to effective partograph use. The goal of the PartoPen project is to increase the effectiveness of the partograph using an interactive digital pen with custom software, together with partograph forms printed with a background dot pattern that is recognized by the pen. This paper describes the design and implementation of the PartoPen system, and the technical evolution of the PartoPen system during studies that evaluated the PartoPen in use in Nairobi, Kenya from June 2012 -- August 2012.
