Use of social media by Spanish hospitals: perceptions, difficulties, and success factors.

This exploratory study has two aims: (1) to find out if and how social media (SM) applications are used by hospitals in Spain and (2) to assess hospital managers' perception of these applications in terms of their evaluation of them, reasons for use, success factors, and difficulties encountered during their implementation. A cross-sectional survey has been carried out using Spanish hospitals as the unit of analysis. Geographical differences in the use of SM were found.
