[Prognostic factors of mortality one year after a hip fragility fracture. Anoia hip study]. / Factores pronósticos de mortalidad al año de una fractura de cadera por fragilidad ósea. Estudio Maluc Anoia.

INTRODUCTION: Most of the patients who had a hip fragility fracture are characterized by advanced age, frailty, multimorbidity and high mortality rate into the first year. Our aim is to describe the prognostic factors of mortality one year after a hip fragility fracture. MATERIAL AND METHODS: Observational prospective study. During the study period we included patients older than 69 years with hip fragility fracture who were admitted to the Acute Geriatric Unit. RESULTS: We have followed 364 patients, 100 of them died (27.5%). The independent prognostic factors of mortality one year after a hip fragility fracture had been: have a less basis score in Lawton and Brody Scale 0.603 (0.505-0.721) (p< 0.001); have a higher score in Charlson Comorbidity Index 2.332 (1.308-4.157) p = 0.04); have a surgical waiting time ≥ 3 days 3.013 (1.330-6.829) p = 0.008); finding hydroelectrolytic disorders and/or deterioration of glomerular filtration 1.212 (1.017-1.444) p = 0.031) during hospital stay; discriminatory capacity of the area under the curve (AUC) (± 95%): 0.888 (0.880-0.891). CONCLUSIONS: Prognostic predictors of mortality at one year after a hip fragility fracture are those variables that reflect a worse state of health, complications during hospital stay and a longer surgical waiting time.

AIM: Hip fracture as a result of bone fragility is characterized by poor health outcomes in the medium and long term. Our goal was to compare a new orthogeriatric model with the old trauma model and evaluate improvements in clinical management. METHODS: We carried out a comparative unicentric study, a historical sample (trauma model) collected from 1 June 2007 to 31 May 2010, versus a prospective sample (orthogeriatric model) collected from 1 June 2010 until 31 May 2013. We included all patients aged >69 years with hip fracture as a result of bone fragility. RESULTS: A total of 792 patients were evaluated (mean age 84.3 years). The surgical waiting period went from 2.70 days in the trauma model to 1.86 days in the orthogeriatric model (P < 0.001); the average stay was 15.76 days in the trauma model, and for the orthogeriatric model was reduced to 5.90 days (P < 0.001); mortality went from 4.5% to 1.3% (P ≤ 0.010); 1 month readmission for hip dislocation was reduced from 2.3% to 0.5% (P = 0.032). After a 6-month follow up, we had 302 trauma model patients and 287 orthogeriatric model patients. After 1 year, we had 288 patients in the trauma model and 264 patients in the orthogeriatric model. The main cause of abandonment was death, 108 patients (27.3%) in the trauma model and 100 patients (27.5%) in the orthogeriatric model (P = 0.951). CONCLUSIONS: When we compared the two models, we found statistically significant better results in the preoperative waiting period, average stay, hospital mortality and 1 month readmission as a result of hip prosthesis luxation in favor of the orthogeriatric model.
