This table summarizes patient demographics, baseline characteristics, and patient outcomes. Abbreviations: SD = standard deviation; n = number; LOS = length of stay; APACHE II = Acute Physiology and Chronic Health Evaluation, an 13 item instrument with scores from 0 to 71, higher scores representing higher severity of illness[20]; Charlson Comorbidity Index includes 19 categories of comorbidity, with higher scores representing more comorbidity[21]; Functional Comorbidity Index includes 18 items associated with physical function, with higher scores representing higher comorbid illness[22]; ADL = activities of daily living; Katz score is a 6-item instrument assessing independence in bathing, dressing toileting, transferring, continence, and feeding, with higher scores representing more independence[23].
