Measuring Prognosis and Case Mix in Hospitalized Elders The Importance of Functional Status

Abstract

ADL function contains important information about prognosis and case mix beyond that provided by routine physiologic data and comorbidities in hospitalized elders. Prognostic and case-mix adjustment methods may be improved if they include measures of function, as well as routine physiologic measures and comorbidity.

Risk Factors for Mortality and Postoperative Complications After Gastrointestinal Surgery

“…This association has not previously been found by surgical outcome studies, but our findings confirm other reports. 13 The type of operation was associated with postoperative mortality and with gastroduodenal operation as the strongest predictor in elective surgery, and colorectal surgery as the strongest predictor in emergency surgery. The latter finding may account for perforated diverticulitis or colonic obstruction, being emergency conditions known to have a high postoperative mortality.…”

A Population-Based Study of Risk Factors for Stroke After Carotid Endarterectomy Using the ACS NSQIP Database

“…Studies involving other types of surgical procedures have reported that patients with limited capabilities of performing activities of daily living (ADLs) have prolonged hospitalization, and increased morbidity, and mortality [38][39][40]. Previous trials like NASCET had excluded disabled patients [1].…”

High Levels of Comorbidity and Disability Cancel Out the Dementia Effect in Predictions of Long-Term Mortality after Discharge in the Very Old

“…The explained variance of the different variables studied here ranged between 10 and 20%; this is rather low, but it lends insight into their predictive values, knowing that a coefficient of determination (R 2 ) above 80% is needed to give a reliable individual prediction. Previous studies have also shown that poorer functional status before and at the time of hospital admission is associated with higher short- and long-term mortality [33,34] and higher comorbidity scores. Cognitive impairment is also often used as a predictor of poorer hospitalization outcomes, including mortality in particular, but only a few studies have also taken comorbid medical conditions and functional status into account [34,35,36,37].…”
