Karsudden Regional Hospital

Karsudden Regional Hospital (Swedish: Regionsjukhuset Karsudden), located just outside Katrineholm in Södermanland County, is today one of Sweden's largest and most secure forensic psychiatric hospitals. It operates within an enhanced security framework and primarily treats individuals sentenced by courts to forensic psychiatric care, as well as a smaller number of patients transferred from remand prisons or the correctional system who require inpatient psychiatric treatment.

As of 2025, the hospital has 155 inpatient beds across 14 wards, organized into seven units. Patients mainly come from the regions of Stockholm, Sörmland, and Gotland, under formal care agreements. The hospital employs a person-centered care model, emphasizing patient participation and collaboration in treatment and rehabilitation.

The organization includes specialized units such as an activity center, psychology services, social work (counseling), medical staff, medical administration, internal services, finance, and HR, alongside dedicated functions for security, sustainability, and patient safety. The hospital employs over 400 staff members and is supported by a security manager and a quality manager. A central monitoring center, established in 2022, further strengthens operational security.

Clinically, schizophrenia is the most common primary diagnosis among patients, followed by other psychotic disorders. The hospital also treats individuals with severe depression associated with high suicide risk and serious autism spectrum conditions. At least half of the patient population has a history of substance abuse, making integrated psychiatric and addiction care a key part of current practice.
