Background and Objectives: mechanical restraint (MR) is a controversial issue in emergency psychiatry and should be better studied to implement other alternative therapeutic interventions. The aim of this study was to estimate the prevalence of MR in an Italian psychiatric unit and identify the sociodemographic and clinical characteristics as well as the pharmacological pattern associated with MR. Materials and Methods: all subjects (N = 799) consecutively admitted to an Italian psychiatric inpatient unit were recruited. Several sociodemographic and clinical characteristics were recorded. Results: The prevalence of MR was 14.1%. Males, a younger age, and a single and migrant status were associated with the MR phenomenon. MR was more prevalent in patients affected by other diagnoses and comorbid illicit substance use, in patients with aggressive behaviors, and those that were involuntary admitted, leading significantly to hospitalization over 21 days. Furthermore, the patients that underwent MR were taking a lower number of psychiatric medications. Conclusions: Unfortunately, MR is still used in emergency psychiatry. Future research should focus on the dynamics of MR development in psychiatry, specifically considering ward- and staff-related factors that could help identify a more precise prevention and alternative intervention strategies.

Background: The aim of the present study is to identify the main sociodemographic and clinical correlates associated with frequent service users (FSUs) in an Italian psychiatric emergency department. Methods: This study is an observational and prospective clinical investigation. All subjects (N = 549) consecutively admitted to the Psychiatric Inpatient Unit of the IRCCS Ospedale Policlinico San Martino ((Genoa, Italy) were recruited over a period of 18 months. Results: On average, FSUs were more likely to be single (75.0% vs. 64.0, p = 0.001), younger (38.79 years ± 14.68 vs. 45.94 years ± 16.94, p = 0.028), with an earlier onset (20.15 years ± 7.22 vs. 29.33 years ± 15.96, p < 0.001), and longer length of hospitalisation (13.65 days ± 12.40 vs. 9.89 ± 10.15, p = 0.006) compared to non-FSUs. While bipolar disorder was the most common primary diagnosis in both FSUs and non-FSUs, cluster B personality disorder was particularly elevated in FSUs (30.3% vs. 10.4%, p < 0.001). Furthermore, FSUs were more prone to substance use disorder (63.6% vs. 40.0%, p < 0.001), particularly cannabis (45.5% vs. 15.3%, p < 0.001), cocaine (33.3% vs. 10.4%, p < 0.001), and heroin (19.7% vs. 5.8%, p < 0.001), and were more likely to have non-suicidal self-injuries (21.2% vs. 6.8%, p < 0.001). FSUs were significantly more likely to be discharged against medical advice (18.2% vs. 5.6%, p < 0.001) or to have at least one escape attempt from the psychiatric ward (12.1% vs. 0.8%, p < 0.001). Conclusions: Specific clinical and social profiles of patients who repeatedly utilised the services of a psychiatric emergency department have been identified. Our findings can be used to develop suitable structures to support and reintegrate FSUs into society and work life.
