[Risk factors for the development of medical complications in patients with hip fracture]

Abstract

Objective: To evaluate the clinical features and outcome of inpatients with hip fracture and to investigate the clinical variables associated with the risk of medical complications.

Methods: Prospective study of hip fracture patients aged 65 or more, admitted to the Department of Orthopaedic Surgery of the Xeral-Calde Hospital, in Lugo, Spain, in 2008. The different clinical and biochemical variables as regards the baseline health status and presentation features of the hip fracture and its complications were all recorded. The factors associated with the development of medical inpatient complications, including death, were determined, using univariate and multivariate analyses.

Results: A total of 258 patients were studied. The mean age was 82.2 (9.5) years, and 76% were women. The fracture was osteoporotic in 96.8%, and 92.6% were treated surgically. The mean Barthel index was 72.9 (25.7) and the age adjusted Charlson comorbidity index was 5.2 (1.5). A total of 63.9% patients had a major medical complication during their hospital stay. Mortality was 5.8%. The following variables were associated with the development of medical inpatient complications: Barthel index (OR=2.21; 95% CI, 1.1-4.25; p=0,01), age (OR=1.09; 95% CI, 1.02-1.12; p=0.006), haemoglobin at admission (OR=0.76; 95% CI, 0.62-0.93; p=0.01).

Conclusions: Patients with hip fracture are fragile elderly with a high degree of functional dependence and comorbidity. Those with a high risk of developing medical inpatient complications can be identified at admission.
