Appraisal of: Mattioli S, Farioli A, Cooke RMT, Baldasseroni A, Ruotsalainen J, Placidi D, et al. Hidden effectiveness? Results of hand-searching Italian language journals for occupational health interventions. Occup Environ Med 2012;69(7):522-524.
The study compared the yield of hand-searching with optimised electronic search strategies in retrieving occupational health (OH) intervention studies published in a language other than English.
The authors systematically hand-searched and screened reports of OH intervention studies published in Italian in peer-reviewed scientific journals between 1990 and 2008. The Cochrane Occupational Safety and Health Review Groups (OSHRG) most sensitive search string retrieved all 16 articles published in the Italian language journals that were indexed in MEDLINE.
These findings suggest that a sensitive electronic search strategy may be able to find most of the OH interventions published in languages other than English that are indexed in MEDLINE.
