Developing a portable field unit to improve well-child care

BACKGROUND: Pediatric growth tracking has been identified as a top priority by international health agencies to assess the severity of malnutrition and stunting. However, remote low-resource settings often lack the necessary infrastructure for longitudinal analysis of growth for the purposes of early identification and immediate intervention of stunting. METHODS: To address this gap, we developed a portable field unit (PFU) capable of identifying a child over the course of multiple visits, each time adding new anthropomorphic measurements. We conducted a preliminary field evaluation of the PFU by using the unit on two distinct visits to three schools in the area surrounding a medical clinic in rural San Jose, Honduras. The unit was used to assess children at each school as part of the community outreach. RESULTS: Community outreaches to three schools were conducted by two distinct teams, where they used the device to assess 210 children. Of the 180 children registered during the first visit, 112 were re-identified and assessed on the subsequent visit. Twenty-four instances of moderate-to-severe malnutrition were identified and referred for further evaluation to the central clinic. CONCLUSION: This initial assessment suggests that the PFU could be an effective means of identifying at-risk children.
