What ARQ Centrum '45 does

ARQ Centrum '45 is the Dutch national expertise center (landelijk expertisecentrum) for the diagnostics and treatment of complex psychotrauma, operating as a non-profit entity within the ARQ organizational group. The organization serves individuals whose trauma complaints have not responded to previous treatments or who cannot be treated elsewhere, including uniformed professionals (veterans, police, firefighters, ambulance personnel, journalists), WWII survivors and their families, refugees and asylum seekers, children and families, victims of sexual violence, and individuals with traumatic grief. Common comorbidities treated alongside PTSD include depression, anxiety, sleep disorders, anger management difficulties, and addiction symptoms.

The service portfolio comprises four core modalities: specialized diagnostic assessment and second opinions, individualized and group-based outpatient treatment delivered at locations in Diemen and Oegstgeest, high-intensity inpatient care at the Kasteellaan kliniek in Oegstgeest (stays ranging from one week to eight months for individuals and families), and online therapy via e-health modules. Underlying technology includes the Quli digital personal health environment (PGO) for patient access to care information and family/caregiver sharing, plus remote e-health delivery modules. Clinical practice is anchored in the GGZ Zorgstandaard Psychotrauma- en stressorgerelateerde stoornissen from Akwa GGZ and is reinforced by 75+ scientific publications produced through ongoing university collaborations.

Revenue is generated through Dutch health insurance reimbursements under the Zorgverzekeringswet, with patients accessing services primarily through GP and specialist referrals, supplemented by consultation services to referring physicians (including 123Consultatie). The organization holds the TOPGGz quality mark recognizing high-specialty function and research integration. Marketing relies on LinkedIn, newsletter distribution via Spotler, and an annual ARQ Zomerreferaat lecture event, with the broader ARQ group providing additional cross-referral channels. The managing director is Eddy Sas, and the entity operates from Oegstgeest with three physical locations across Diemen and Oegstgeest.
