ICU admission criteria for patients with self-poisoning; reduction of admissions is possible

Objective: To evaluate the possibility of formulating stricter ICU admission criteria for patients with self-poisoning. Design: Retrospective study of patients with self-poisoning in an ICU. Setting: A university hospital. Patients: Patients admitted to the ICU with self-poisoning. Methods: Patients who underwent specific ICU interventions during admission were compared with patients who did not receive these interventions. A modification of the APACHE II score (M-APS), reflecting the actual health situation, and admission criteria as proposed by Brett were assessed. By multiple logistic regression analysis, a new scoring system was suggested for this group of patients (self-poisoning admission screening score: SPASS). Results: The study included 79 patients: 13 were defined as needing ICU admission and one patient died. Using Brett's criteria, M-APS and SPASS, it is possible to reduce admissions by 63%, 46% and 67% respectively in this group of patients. Conclusion: Reduction of patients on the ICU due to self-poisoning is possible using admission criteria; however, prospective evaluation should be performed.
