Abbreviations: BMI: body mass index; ADL: activities of daily living; IADL: instrumental activities of daily living; FSS-ICU: functional status score for the intensive care unit; APACHE: acute physiology and chronic health evaluation; Incl: including; LOS: length of stay.
The Brazil – Neto study doesn’t have ICU admission diagnosis data that fit into the above categories.
ADL score has a range of 0-6 with higher score indicating better functional status
IADL score has a range of 0-8 with higher score indicating better functional status;
FSS-ICU score has a range of 0-35 with higher score indicating better functional status;
APACHE II score has a range of 0-71, with higher score indicating greater severity of illness within first 24 hours of ICU admission.
Percentages may not sum to 100 (%) because of rounding.
