Polypharmacy prior to in-hospital cardiac arrest among patients with cardiopulmonary diseases: A pilot study.

Background: Patterns of medication administration prior to in-hospital cardiac arrest (I-HCA) and the potential impact of these on patient outcomes is not well-established. Accordingly, types of medications administered in the 72 h prior to I-HCA were examined in relation to initial rhythms of I-HCA and survival.

Methods: A retrospective, pilot study was conducted among 96 patients who experienced I-HCA.
