Abstract
Public–private partnerships (PPPs) have become popular worldwide as a way of improving health care service delivery. In order to enhance our knowledge of PPPs in the health care sector, we conduct a systematic review of forty-six articles published in peer-reviewed journals for the period of 1990–2011. Six lines of research in the PPP domain are identified: effectiveness, benefits, public interest, country overview, efficiency and partners. The main findings suggest that although PPPs are used to address internationally emerging public health issues, questions as to their actual effectiveness, efficiency and convenience, still remain unanswered. We propose viable recommendations and ideas for future research.
