Study selection and Data Abstraction

We conducted a comprehensive search on Pubmed, Embase, Web of Science, Scopus and Cochrane databases for studies published as of June 2013, using search terms related to HIV, linkage to care, and emergency department (Appendix 1). Only full text articles and conference abstracts were selected. Studies that reported data in commentaries or editorials, contained pediatric data, had no LTC data, or had overlapped data from the same study site were excluded. The study selection process and the result are presented in Appendix 1.
