The aim of this scoping review is to synthesize the available evidence on the prevalence rates of healthcare workers being victims of violence perpetrated by patients and visitors in Italy. PubMed, Scopus, Web of Science and CINAHL were systematically searched from their inception to April 2021. Two authors independently assessed 1182 studies. All the scientific papers written in English or in Italian reporting primary quantitative and/or qualitative data on the prevalence of aggression or sexual harassment perpetrated by patients or visitors toward healthcare workers in Italy were included. Thirty-two papers were included in the review. The data extracted were summarized in a narrative synthesis organized in the following six thematic domains: (1). Methodology and study design; (2). Description of violent behavior; (3). Characteristics of health care staff involved in workplace violence (WPV); (4). Prevalence and form of WPV; (5). Context of WPV; and (6). Characteristics of violent patients and their relatives and/or visitors. The proportion of studies on WPV differed greatly across Italian regions, wards and professional roles of the healthcare workers. In general, the prevalence of WPV against healthcare workers in Italy is high, especially in psychiatric and emergency departments and among nurses and physicians, but further studies are needed in order to gather systematic evidence of this phenomenon. In Italy, and worldwide, there is an urgent need for governments, policy-makers and health institutions to prevent, monitor and manage WPV towards healthcare professionals.
