The restrained patients were significantly younger and more likely to be men, to reside outside the wards' catchment areas, and to have an immigrant background. Restrained patients also had more admissions and longer inpatient stays than nonrestrained patients and were more likely to be involuntarily referred and to have one or more of the following ICD-10 diagnoses: a substance use disorder, schizophrenia or a related psychotic disorder, and bipolar disorder. Binary logistic regression analyses, adjusting for age, gender, immigrant background, and catchment area, indicated that the number of admissions, length of stay, legal basis for referral, and diagnosis each independently predicted the use of restraint. No interactions were found.
