Experimental: Individually tailored rehabilitation intervention + usual care

A comprehensive neurocognitive assessment and a thorough individual assessment of rehabilitation needs will be conducted to inform the individually tailored intervention plan. Core intervention elements are: 1) comprehensive assessment of individual rehabilitation needs including neuropsychology tests in order to make a individually tailored intervention plan coordinated with the multidisciplinary rehabilitation team, 2) providing strategies to lessen impact for the individual cognitive impairment, 3) educating survivors and relatives about the impact of a cardiac arrest and consequences on daily life, 4) work preparation, including establishment of routines and opportunities to practice work skills and 5) collaboration with the local municipality's job centre and employers to plan, support and monitor graded RTW, 6) short term therapy by psychologist dealing with thoughts and behaviour in relation to cardiac arrest.

Active_comparator: Usual care

All participants including those allocated to the usual care group will be seen by an occupational therapist if their MoCA screening score ≤26. Furthermore, if considered relevant by the discharging unit, survivors are referred for rehabilitation provided and delivered in the local municipality where the participant is resident. The content of the rehabilitation will typically be based on the content of the rehabilitation plan from the discharging hospital unit and an individual assessment of the survivors' expressed needs, within the local municipality where the participant is resident.
