Survival, Outcomes, and Use of Acuity Scoring Systems Following Tracheotomy in Veteran Patients

Abstract

Objectives: To determine whether established prognosis tools used in the general population of critically ill patients will accurately predict tracheotomy-related outcomes and survival outcomes in critically ill patients undergoing tracheotomy. Methods: Retrospective chart review of 94 consecutive critically ill patients undergoing isolated tracheotomy. Results: Logistic Organ Dysfunction System (LODS) and sepsis-related organ failure assessment (SOFA) scores, 2 validated measures of acuity in critically ill patients, were calculated for all patients. The only tracheotomy-related outcome of significance was the finding that patients with an LODS score ≤6 were more likely to become ventilator independent ( P < .015). Higher LODS or SOFA scores were associated with in-house death (LODS, P = .001, SOFA, P = .008) and death within 90 days (LODS, P = .009, SOFA, P = .031), while death within 180 days was associated only with a higher LODS score (LODS, P = .018). When controlling for age, there was an association between both LODS ( P = .015) and SOFA ( P = .019) scores and death within 90 days of tracheotomy. Conclusions: The survival outcome for critically ill patients undergoing tracheotomy seems accurately predicted based on scoring systems designed for use in the general population of critically ill patients. Logistic Organ Dysfunction System may also be useful to predict the likelihood of the tracheotomy-related outcome of ventilator independence. This suggests that LODS scores may be helpful to palliative care clinicians as part of a shared decision-making aid in critically ill, ventilated patients for whom tracheotomy is being considered.
