The second group will be recruited from patients who survive cardiac arrest from the start of study date. Participants in this group (patient and a relative/friend) will be approached by a member of the research team whilst in hospital and an informed consent will be obtained. Baseline data will be acquired using the recommended questionnaires and a supportive psychological intervention will be offered in the form of a dedicated telephone helpline, attendance at a cardiac arrest clinic and early referral to clinical psychiatrist if appropriate for psychological help. At around 6 months from the date of cardiac arrest, participants will be invited to attend a clinic to reevaluate post cardiac arrest care using the same recommended questionnaires. At the end of the study, the data between the 2 groups will be analysed.
