Objective : To identify incidence, characteristics and outcomes of patients who were re-admitted to surgical intensive care
units (SICUs).
Material and Method: Multicenter prospective cohort study conducted in 9 university-affiliated surgical ICUs in Thailand
(THAI-SICU study) from April 2011 to January 2013.
Results : A total of 144 patients (3.1%) re-admitted to our surgical ICUs from 4,652 cases were recruited. Re-admission
baseline characteristics were advanced age (mean = 71 years), low body mass index, and higher APACHE-II and SOFA score
within 24 hours of first ICU admission. Many significant comorbidities were found in the re-admission group, including:
hypertension, cardiovascular diseases, and respiratory diseases. ICU mortality and hospital mortality were higher in re-
admission group than those in the non re-admission group (20.1% vs. 9.3%, p<0.001 and 27.8% vs. 11.3%, p<0.001,
respectively). The relative risk ratio for mortality between re-admission and non re-admission in ICU was 2.17 times and in
hospital mortality was 2.46 times greater. Independent potential risk factors for re-admission were age (OR 1.028, 95% CI
1.001-1.051), emergency surgical intervention (OR 1.978, 95% CI 1.027-3.813), transfer back from general wards (OR
4.175, 95% CI 2.020-8.628), and respiratory failure needing mechanical ventilation (OR 2.167, 95% CI 1.065-4.407).
Conclusion : Re-admission was found in 3.1% of cases in our surgical ICUs. This problem is associated with significantly
higher ICU and hospital mortality. Risk factors of re-admission were patient age, emergency surgery, re-admission from
general wards, and need for respiratory support.
