title: Could hospital patients' hands constitute a missing link?
abstract: The relationship between contamination of patients' hands and transmission of healthcare-associated infection has received only limited attention, but may represent a previously overlooked but potentially significant link in the chain of infection. This paper aims critically to review the literature to determine whether this possible epidemiological relationship is worthy of further consideration. Studies that have investigated the microbiology or hand hygiene behaviours of patients and other groups are examined to establish their limitations and implications for future practice and research. Examples of healthcare-associated infections where improving patient hand hygiene may have a favourable impact on transmission, and how this might be achieved within the context of current UK health service initiatives, are discussed. It is recommended that systematic studies of the role of patients' hands in the chain of hospital infection should be undertaken.
