AbstractBackgroundLow-and middle-income countries (LMICs) not only experience the largest burden of humanitarian emergencies but are also disproportionately affected by non-communicable diseases (NCDs). Interventions addressing NCDs require humanitarian entities to consider complex challenges such as continuity of care, diagnostics, logistics and cost of care for recurrent or expensive treatments, yet primary focus on the topic is lacking. We conducted a systematic review on the effects of humanitarian disasters on NCDs in LMICs with the primary aim of identifying studies on epidemiology, interventions, and treatment. Key interventions were identified and their effects on populations in disaster settings were reviewed.MethodsA systematic search was conducted in MEDLINE, MEDLINE (PubMed, for in-process and non-indexed citations), Social Science Citation Index, and Global Health (EBSCO) for indexed articles published before December 11, 2017. Publications reporting on interventions targeting NCDs during disasters in LMICs were included if they incorporated core intervention components as defined by the United States Department of Health and Human Services. Two separate screeners independently evaluated the titles, abstracts and full text of the eligible articles, with vetting by a third reviewer. Key intervention components including target population, phase of crisis, and measured outcomes among others were extracted into a template and synthesized using a thematic analysis approach. The full systematic review is registered at PROSPERO(CRD42018088769).ResultsOf 85 articles eligible for the full systematic review, only seven articles describing interventions met inclusion criteria. Studies focused reporting on the response (n=4) and recovery (n=3) phases of disaster, with no studies reporting on the mitigation or preparedness phases. Successful interventions conducted extensive pre-deployment risk assessments to assess the burden and distinct epidemiology of NCDs amongst affected populations, worked in close cooperation with local health services, assessed individual needs of sub-populations in disaster regions in the response phase, promoted task shifting between humanitarian and development actors, and adopted flexibility in guideline implementation. Training and capacity building of staff were found to be essential elements of successful interventions due to an assessed lack of experience of healthcare workers in disaster settings with NCDs and successfully allowed for incorporation of community health workers.ConclusionsWe found only limited interventions designed to address NCDs in humanitarian emergencies, with a particular dearth of studies addressing the mitigation and preparedness phases of humanitarian response. Delivering interventions for NCDs in humanitarian emergencies requires improved collaboration between humanitarian and development actors in addition to improved NCD training and capacity building amongst healthcare workers in disasters settings.
