Characteristics of patients requiring prolonged length of stay in a surgical intensive care unit in Barbados

Objective: To evaluate the clinical characteristics and costs incurred for patients who stayed for a prolonged period in a surgical intensive care unit (ICU) Design and Methods: Data of all patients admitted to a surgical ICU in Barbados during the period of two years from July 1999 to June 2001 were prospectively collected Demographic data, diagnoses on admission and Acute Physiology and Chronic Health Evaluation (APACHE II) score were recorded Costs for treatment were calculated from using a cost block model. The characteristics of patients who had a prolonged stay (> 14 days) were compared with a concurrent cohort of patients who stayed less than 14 days. Results: Of 438 admissions, 58 (13.2%) stayed in the ICU for more than two weeks. The overall age, hospital outcome, APACHE II scores in the prolonged stay group were significantly higher than that of the patients who stayed less than two weeks. Cost analysis showed about six times more expenditure in the long stay patients ($US 3 800 vs $US2 4000). Of the prolonged stay ICU patients, 29.2% would have required only a step-down unit due to less severity of illness as evidenced by their low mean APACHE II scores [7.3 +/- 2.6 (SD)] compared to overall mean APACHE H score 10.7 +/- 7.5 (SD). Conclusion: The study highlighted the need for a step-down unit and a protocol to transfer eligible patients to such a unit.
