Severity of cognitive impairment as a prognostic factor for mortality and functional recovery of geriatric patients with hip fracture.

AIM: To identify how the severity of dementia influences functional recovery and mortality in elderly patients hospitalized for hip fracture. METHODS: An observational retrospective study of 1258 patients aged older than 69 years and diagnosed with hip fracture who received care within an orthogeriatrics unit from 2004 to 2008 was carried out. During a 12-month follow-up period, functional recovery and mortality outcomes were measured. RESULTS: Dementia was present in 383 (28.1%) patients: it was mild in 183 (48%), moderate in 102 (26.5%) and severe in 98 (25.5%). Compared with patients with preserved cognitive status, patients with dementia had the following statistically significant differences (means [standard deviation] or percentage): older age (preserved, 82.29 years [6.5 years]; mild, 83.63 years [6.1 years]; moderate, 83.47 years [5.9 years]; severe, 84.46 years [6.1 years]; P < 0.001); lower Barthel Index (89.7 [21.6], 72.7 [24.6], 58.9 [28.6], 38.0 [28.1]; P < 0.001); delirium (11.7%, 25.6%, 37.6%, 44.7%; P < 0.001); less ambulation at 6 months postdischarge (83.9%, 72.8%, 56.9%, 41.7%; P < 0.001); and higher mortality at discharge (4%, 5.7%, 8.2%, 10.6%; P < 0.001) and 12 months after discharge (21.2%, 32.3%, 46.3%, 53.5%; P < 0.001). Patients with severe dementia had lower probability of functional recovery at discharge (OR 0.272, 95% CI 0.140-0.526, P < 0.001) and 6 months after discharge (OR 0.439, 95% CI 0.197-0.979, P = 0.04), as well as a greater probability of dying (HR 1.640, 95% CI 1.020-2.635, P = 0.04). CONCLUSIONS: We observed higher 12-month mortality and less functional recovery with increasing severity of dementia.

Early interdisciplinary hospital intervention for elderly patients with hip fractures : functional outcome and mortality.

OBJECTIVES: Hip fractures are associated with high levels of co-morbidity and mortality. Orthogeriatric units have been shown to be effective with respect to functional recovery and mortality reduction. The aim of this study is to document the natural history of early multidisciplinary intervention in elderly patients with hip fractures and to establish the prognostic factors of mortality and walking ability after discharge. METHODS: This observational, retrospective study was performed in an orthogeriatric care unit on patients aged >70 years with a diagnosis of hip fracture between 2004 and 2008. This study included 1363 patients with a mean age of 82.7 + 6.4 years. RESULTS: On admission to the unit, the average Barthel score of these patients was 77.2 + 27.8 points, and the average Charlson index score was 2.14 + 2.05. The mean length of stay was 8.9 + 4.26 days, and the readmission rate was 2.3%. The in-hospital mortality rate was 4.7%, and the mortality rates at one, six, and 12 months after discharge were 8.7%, 16.9%, and 25.9%, respectively. The Cox proportional hazards model estimated that male sex, Barthel scale, heart failure, and cognitive impairment were associated with an increased risk of death. With regard to functionality, 63.7% of the patients were able to walk at the time of discharge, whereas 77.4% and 80.1% were able to walk at one month and six months post-discharge, respectively. The factors associated with a worse functional recovery included cognitive impairment, performance status, age, stroke, Charlson score, and delirium during the hospital stay. CONCLUSIONS: Early multidisciplinary intervention appears to be effective for the management of hip fracture. Age, male sex, baseline function, cognitive impairment and previous comorbidities are associated with a higher mortality rate and worse functional recovery.
