To analyze the utilization of intensive care unit (ICU) days in a Canadian medical-surgical ICU and to identify ICU patients with prolonged ICU length of stay (LOS).
Prospective descriptive study.
A Canadian tertiary care medical-surgical ICU.
Consecutive patients admitted to an adult medical-surgical ICU.
Neurosurgical, cardiac surgical, and coronary care unit patients were excluded.
For each ICU admission, patient demographics, diagnosis, Acute Physiology and Chronic Health Evaluation II (APACHE II) score, ICU LOS, and hospital mortality were collected.
The patients'risk of death was calculated using the APACHE II equation.
Admissions were stratified by ICU LOS into four groups : 1 to 2,3 to 6,7 to 13, and >=14 days.
Among the four LOS groups, the number of ICU days and observed and predicted death rates were compared.
Admissions were also stratified by risk of death into five probability range quintiles.
Among the five risk groups, ICU LOS was compared between survivors and nonsurvivors.
A total of 1,960 admissions utilized 9,298 ICU days.
ICU LOS (mean ± SEM) was 4.74 ± 0.2 (median, 2 ; range, 1 to 178) days.
Short-stay patients (ICU LOS<2 days) accounted for 60.3% of total admissions but consumed only 16.4% of total ICU days.
Long-stay patients (ICU LOS >=14 days) accounted for 7.3% of total admissions but consumed 43.5% of total ICU days. (...)
