  • Can severity of a humanitarian crisis be quantified? Assessment of the Inform severity index

    Open AccessVelma K Lopez, Angeliki Nika et al.ARTICLEGlobalization and Health2023

    BACKGROUND: Those responding to humanitarian crises have an ethical imperative to respond most where the need is greatest. Metrics are used to estimate the severity of a given crisis. The INFORM Severity Index, one such metric, has become widely used to guide policy makers in humanitarian response decision making. The index, however, has not undergone critical statistical review. If imprecise or incorrect, the quality of decision making for human…

  • Lessons learned from implementation of a national hotline for Ebola virus disease emergency preparedness in South Sudan

    Open AccessVelma K Lopez, Sharmila Shetty et al.ARTICLEConflict and Health2021

    Basic surveillance information was not collected from callers. To trigger effective outbreak investigation from hotline calls, the hotline should capture who is reporting and from where, symptoms and travel history, and whether this information should be further investigated. Electronic data capture will enhance data quality and availability of information for review. Additionally, the magnitude of missed calls presents a major challenge. When ca…

  • Latent variable modeling to develop a robust proxy for sensitive behaviors

    Open AccessVelma K Lopez, Brady T West et al.ARTICLEBMC Public Health2019

    Effective implementation and evaluation of sanitation programs requires accurate measurement of latrine use. Psychosocial variables, such as norms, perceptions, and attitudes may provide robust proxy-measures. Future longitudinal studies will help to strengthen the use of these surrogate measures, as many of these factors may be subject to secular trends. Additionally, subgroup analyses will elucidate how our proxy indicators of latrine defecatio…

  • Trends of child undernutrition in rural Ecuadorian communities with differential access to roads, 2004–2013

    Open AccessVelma K Lopez, Carolyn Dombecki et al.ARTICLEMaternal and Child Nutrition2018

    Road access can influence protective and risk factors associated with nutrition by affecting various social and biological processes. In northern coastal Ecuador, the construction of new roads created a remoteness gradient among villages, providing a unique opportunity to examine the impact of roads on child nutritional outcomes 10 years after the road was built. Anthropometric and haemoglobin measurements were collected from 2,350 children <5 ye…
