[Limiting ICU admission from emergency services and wards]

Decisions not to admit a patient to intensive care units (ICU) as a way of limiting life support treatment (LLST) is a practice that can affect the operation of the emergency services and the way in which patients die.

Post hoc analysis of the ADENI-UCI study. The main variable analysed was the reason for refusal of admission to the ICU as a measure of LLST. For the present post hoc analysis, the registered patients were divided into 2 groups: the patients assessed in the intensive medicine services from the emergency department and the patients assessed from the conventional hospitalization areas. Student t was used in the comparative statistics when the mean values of the patient sub-cohorts were compared. Categorical variables were compared with the χ² tests.

The ADENI-ICU study included 2,284 decisions not to admit to the ICU as a measure of LLST. Estimated poor quality of life (p=.0158), the presence of severe chronic disease (P=.0169) and futility of treatment (P=.0006) were percentage decisions with greater weight within the population of hospitalized patients. The percentage of disagreement between the consulting physician and the intensivist was significantly lower in patients assessed from the emergency services (P=.0021).

There are appreciable differences in the reasons for consultation, as well as in those for refusal of admission to an ICU between the consultations made from an emergency department and a conventional hospitalization facility.
