Brief summary

Unexpected deaths and unplanned intensive care unit (ICU) admissions are common during hospital stay and are often preceded by warning abnormalities in patients' vital signs. These abnormalities trigger Medical Emergency Team (MET) activation and up to 15% of patients visited by the MET is admitted to the ICU with an overall hospital stay after the MET intervention of approximately 2 weeks. Phosphocreatine (PCr) is a natural energy-buffering molecule associated with signals of mortality reduction in patients with acute cardiac conditions (according to meta-analytic finding from our group) and with encouraging beneficial effects on other acute organ failures (e.g. brain). The investigators designed a multi-center, randomized, placebo-controlled trial to confirm the promising beneficial effects of PCr in hospitalized patients. The investigators expects a reduction in hospital stay (measured as an increase in days alive and out of hospital at 30 days) when PCr is added to standard treatment in patients requiring MET intervention.

Design outcomes

Primary

MeasureTime frameDescription
days alive and out of hospital at 30 days.day 30 or hospital dischargeTo compare the effect of phosphocreatine (PCr) (experimental group), versus placebo (saline solution-control group) on the number of days alive and out of hospital at 30 days.

Secondary

MeasureTime frameDescription
Cognitive functionday 30Evaluation of cognitive function using the Cognitive Telephone Screening Instrument (COGTEL). The COGTEL is a test that evaluates the cognitive performance of survived patients 30 days after randomization. This scale has a minimum of zero points and a maximum of 100.
Rate of arrhythmia needing treatmenthospital discharge (which usually occurs in the 30days after randomization)Clinically relevant arrhythmias will be recorded and confirmed by an ECG. Rate of major arrhythmias divided into supraventricular arrhythmias, ventricular arrhythmias, bradyarrhythmias, and need for antiarrhythmics will be registered.
