Link between blood bicarbonate level and risk of ICU admission or death within 48 hours after ER arrival

Statistical Association Between Bicarbonate Levels and Death or Admission to Intensive Care Within 48 Hours in Patients Presenting to the Emergency Department

Centre Hospitalier Departemental Vendee · NCT07340060

This will test whether a patient's bicarbonate level measured on arrival to the emergency department can help predict the risk of death or transfer to intensive care within 48 hours.

What this trial studies

This is an observational analysis of adult patients who had a blood ionogram on admission to the emergency department at Centre Hospitalier Departemental Vendée. Researchers will compare initial bicarbonate values with short-term outcomes (death or admission to intensive care within 48 hours) using routinely collected clinical data. Statistical models will be used to estimate the strength of the association and adjust for key clinical covariates. No experimental treatments are given and participation requires only that patients consent to use of their clinical data.

Who should consider this trial

Good fit: Adults who present to the emergency department, have a blood ionogram performed at admission, and are able and willing to allow use of their clinical data are the intended participants.

Not a fit: Children, patients who did not have a blood ionogram at admission, or those whose clinical decisions are already guided by more definitive measures may not benefit from this analysis.

Why it matters

Potential benefit: If successful, the finding could help emergency clinicians identify high-risk patients sooner and prioritize monitoring or early interventions.

How similar studies have performed: Prior observational research has linked acid–base abnormalities, including low bicarbonate, with worse short-term outcomes, though predictive value specifically for 48-hour ICU admission or death is not fully established.
