There is relatively less literature available on in-hospital cardiac arrest (IHCA) as opposed to that of out-of-hospital cardiac arrest (OHCA). Although IHCA and OHCA patients may differ at baseline, they share similar factors that are associated with survival. Important variables need to be standardised for reporting. Principles such as the 'chain of survival' remain applicable in the response. Early escalation protocols and medical emergency teams, together with streamlined activation pathways and staff training, are crucial. Post-resuscitation care bundles should be implemented.
