ObjectiveTo assess the effect of proactive ethics consultation on documented patient care communications and on declsions regarding high-risk intensive care unit (ICU) patients.DesignProspective, controlled study.Patients96 hrs of continuous mechanical ventilation.Interventions96 hrs of continuous mechanical ventilation. Patient care planning, for subjects in the proactive group, was reviewed with physicians and with the care team using a standardized set of prompting questions designed to focus discussion of key decision-making and communication issues for critically and terminally ill patients. Issues and concerns were identified and action strategies were suggested to those in charge of the patient's care. Formal ethics consultation, using a patient care conference model, was made available upon request.Measurements and Main ResultsPost discharge chart reviews of the three groups indicated no statistically significant differences on important demographic variables including age, gender, and acuity. Comparisons of survivors and nonsurvivors for the three groups indicated, at statistically significant levels, more frequent and documented communications, more frequent decisions to forgo life-sustaining treatment, and reduced length of stay in the ICU for the proactive consultation group.ConclusionProactive ethics consultation for high-risk patient populations offers a promising approach to improving decision-making and communication and reducing length of ICU stay for dying patients.
