RESUMO
OBJECTIVES: Health information sharing continues to play a crucial yet underappreciated role in humanitarian settings, to guide evidence-based disease prevention, detection and response. We conducted a mixed-methods study to investigate and analyse existing approaches and practices to health information sharing across humanitarian settings over the past 20 years. SETTING: We sought to identify studies from any self-described humanitarian setting worldwide, and also targeted experts familiar with refugee settings, specifically long-term camps in Kenya, Jordan and Bangladesh, for key informant interviews. PARTICIPANTS: The systematic review did not directly involve participants. The identified reports were largely retrospective and observational, and focused on populations affected by humanitarian crises worldwide. Participants in the key informant interviews were experts with either broad geographical expertise or direct experience in refugee camp settings. PRIMARY AND SECONDARY OUTCOME MEASURES: Our study was qualitative, and both the systematic review and analysis of key informant interview responses focused on identifying themes related to barriers, tools and recommendations used between stakeholders to share health information, with a particular emphasis on infectious disease and surveillance data. RESULTS: We identified logistical challenges, difficulties with data collection and a lack of health information sharing frameworks as the most significant barriers to health information sharing. The most important tools to health information sharing included the use of third-party technologies for data collection and standardisation, formalised health information sharing frameworks, establishment of multilevel coordination mechanisms and leadership initiatives which prioritised the sharing of health information. CONCLUSIONS: We conclude that health information sharing can be strengthened in humanitarian settings with improvements to existing frameworks, coordination and leadership tools, in addition to promotion of health information communication. Furthermore, specific recommendations for improving health information sharing should be pursued according to the nature of the humanitarian setting and the efficacy of the health system present.
