Perpetrator, worker and workplace characteristics associated with patient and visitor perpetrated violence (Type II) on hospital workers: a review of the literature and existing occupational injury data.

Problem: Non-fatal type II violence experienced by hospital workers (patient/visitor-on-worker violence) is not well described.

Methods: Hospital administration data (2004-2009) were examined for purposes of calculating rates of type II violent events experienced by workers. We also conducted a review of the hospital-based literature (2000-2010) and summarized findings associated with type II violence.
