[Systematic review and evidence mapping of empirical studies on health status and medical care among refugees and asylum seekers in Germany (1990-2014)].

BACKGROUND: Owing to a lack of routine statistics on the health status and medical care of asylum seekers, empirical studies play a major role in the mapping of these aspects.
OBJECTIVES: The aim of this review is to provide a comprehensive overview of the research landscape in this area, synthesizing knowledge from empirical studies and identifying evidence gaps.
METHODS: A three-tiered search strategy included searching for empirical studies in national/international databases and on the internet, screening reference lists, and contacting experts. Studies meeting predefined inclusion criteria were thematically organized and described in a narrative synthesis.
RESULTS: The searches generated 1,190 hits; 52 articles met the inclusion criteria. Of these, 41 were quantitative studies (78.9 %), 10 qualitative (19.2 %), and 1 was a review (1.9 %). A total of 30 primary articles (58.9 %) analyzed mental health aspects, followed by infectious diseases (n = 12, 23.5 %). Qualitative studies, mainly ethnographies and case studies, explored mental health and social determinants of health, providing evidence for the impact of living conditions on health and medical care. Few studies analyzed chronic diseases (n = 3) or childhood illnesses (n = 6). No studies analyzed the health needs or medical care of asylum-seeking women during pregnancy and child birth. In 62.7 % of the primary studies, a single sampling point was used to recruit asylum seekers. Nationwide external validity was given in two quantitative studies.
CONCLUSION: The priority research areas identified are chronic diseases and childhood and maternal health. The divergency and heterogeneity of the studies hamper a comprehensive and comparable acquisition of knowledgeand emphasize the  need for collaborative research to close the existing evidence gaps.
