Acute psychiatric assessments outside hospital by the PAM unit

With the aim to handle acute psychiatric assessments outside the hospital as well as acute suicidal situations, the PAM units operate every day. The vehicles are dispatched from SOS Alarm for assignments all over Stockholm county. From December 2020 there are two cars running from 11 a.m to 9 p.m and from 5 p.m. to 3 a.m. respectively.

The PAM unit is a cooperation between Norra Stockholms psykiatri and AISAB, the somatic ambulance in Stockholm city. AISAB is in charge of the vehicles and a paramedic in each car, while Norra Stockholms psykiatri staffs the car with two specialist nurses. The vehicles are dispatched and managed from the Emergency dispatch centre for assignments across Stockholm county.

The PAM unit uses the same communication system as the police, ambulance and fire brigade. The staff can access medical journals with the digital medical record system in Stockholm using 4G.
