The Effectiveness of Interventions for Non-Communicable Diseases in Humanitarian Crises: A Systematic Review
This systematic review found insufficient evidence on the effectiveness of interventions addressing non-communicable diseases (NCDs) in humanitarian crises. After searching for quantitative published and grey literature produced between 1980 and 2014 on NCD interventions in humanitarian crises in low- and middle-income settings, only 8 studies were identified. The quality of the studies was also limited and there remains an over-reliance on observational study designs. Interventions that incorporate standardisation and facilitate patient follow-up appear beneficial but any findings should be treated with caution given the limited quantity and quality. Substantially more research is needed, particularly using longitudinal and experimental designs, and including data on costs.
