Implications of a recurrent in-hospital cardiac arrest on survival and neurological outcomes

Nearly 1 in 8 patients with an IHCA has a recurrent IHCA, and these patients have worse outcomes than patients with only a single IHCA and those with an IHCA after being hospitalized for an OHCA. Despite worse survival, rates of DNAR and withdrawal of care were lowest for patients with recurrent IHCA. These findings provide important prognostic information for clinicians caring for patients with recurrent IHCA and suggest the need to better align resuscitation and end-of-life decisions with patients' prognoses after IHCA.
