    Research Areas
    • Acute care interventions in Uganda.  This includes: colour coding children under-five (to assist clinical decision making), application of supportive communication/cell phone technologies, oxygen delivery and emergency transportation.
    • Health systems: Scaling up of zinc for the treatment of acute childhood diarrhea in developing countries. 
    • Pediatric post septic shock survival in Uganda: epidemiology and interventions to improve long term outcomes
    • Baseline and follow-up evaluation of a capacity building project that aims to strengthen services and health system support for childhhod epilepsy and cerebral palsy in Guuangzhou, China
    Summary

    Dr. Larson’s primary fields of interest are health systems research, bringing proven and appropriate technologies to scale, and child survival in developing country settings.  Dr. Larson assumed the directorship of the Centre for International Child Health in 2008. 

    Since joining the Centre, he has been focusing on project commitments in Uganda, Kenya, Bangladesh, and China, with research focusing on innovations in support of acute illness management of young children (Uganda, Kenya, Bangladesh) and neuro-developmental disabilities in China.

    Current Projects

    Clinical Effectiveness and Preventive Impact of Zinc Treatment for Acute Diarrhea in Children: A Cluster-randomized Field Trial in Rural Western Kenya
    Zinc deficiency is common in Africa. It has been shown in Asia that zinc as treatment for diarrhea can shorten the course of episodes of diarrhea, as well as prevent future episodes. The use of zinc to treat diarrhea in an African setting, where malaria, HIV and malnutrition are common, has not been well-studied. The objective is to evaluate if zinc treatment for diarrhea in Kenyan children will decrease the community prevalence of diarrhea and to compare clinic vs. home-based distribution of zinc blister packs. This study is in the analysis and write-up phase.

    Scaling Up Zinc: Impact of an NGO sponsored training and support intervention targeting unregulated private sector providers on household diarrhea management practices in rural Bangladesh
    Within the NGO sector, direct provision of health services is provided, however some NGOs also work closely with the private sector providers. This study provides objective evidence of the impact of this approach, using the scale-up of zinc for the treatment of childhood diarrhoea as a test case. The study will be assessing NGO impact among unregulated (unlicensed), rural service providers. Further, this study will serve to assess the value of this model of scaling up activities in the non-state sector with a particular eye toward more generalizable and replicable improvement in quality of care strategies between NGOs and unlicensed private providers.

    Developing and delivering integrated innovations in support of acute care and improved survival of under-five children
    Of the nearly 10 million annual deaths occurring in children under five years of age in less developed countries, over 80% are potentially avoidable.  In addition to measures that prevent disease, affordable, proven acute illness treatment interventions exist that have the potential to save millions of lives each year. This project is currently validating a color coding scheme and proxy measurements for a child’s weight that will guide clinical decision making within village and primary care clinic settings.  This is being done in Uganda, Kenya and Bangladesh.
