Mortalidad intrahospitalaria en adultos mayores chilenos con fractura de cadera: incidencia, causas y otros elementos de interés / Early in-hospital Mortality in Chilean Older People with Hip Fracture

INTRODUCCIÓN: Las fracturas de cadera (FC) presentan alta mortalidad. Existen escasos estudios que profundizan en la mortalidad intrahospitalaria (MIH) asociada. OBJETIVO: Describir MIH en pacientes ≥ 60 años con FC. MATERIALES Y MÉTODOS: Corte transversal, descriptivo y analítico, monocéntrico, de colección completa. Fueron evaluados 647 sujetos, de ambos géneros, ingresados con FC entre 01.01.2010 y 31.12.2012, agrupándolos en fallecidos y egresados vivos. Se registró fallecimientos, género, edad, ubicación anatómica, tipo de traumatismo, lugar de ocurrencia de FC, tiempo fractura-fallecimiento, tiempo de estancia hospitalaria, porcentaje de operados, diagnósticos asociados a FC, diagnóstico de fallecimiento, comorbilidad asociada al diagnóstico de fallecimiento y lugar de fallecimiento. Datos en planilla ortogeriátrica, análisis descriptivo. RESULTADOS: MIH = 3,09%. Edad promedio 84 años. Los diagnósticos de fallecimiento más importantes fueron infecciones (40%) y enfermedad tromboembólica (15%). El 80% presentó comorbilidad crónica relacionada con la causa de fallecimiento. Sin diferencias significativas según edad, género, ubicación anatómica de la FC, lugar de ocurrencia de la FC, tiempo de estancia hospitalaria. Hubo diferencias significativas en cantidad de no operados, mayor en el grupo con MIH (p < 0.000), esperable por sesgo de selección. Es deseable identificar precozmente los sujetos con FC que presentan alto riesgo de MIH. Esto, para definir manejo conservador, optimizar calidad de vida y recursos hospitalarios.

INTRODUCTION: Hip fractures (HIF), have high rates of early mortality. However, there are few studies that deepen in in-hospital mortality (IHM). OBJETIVE: To describe IHM in patients with ≥ 60 years with HIF. MATERIALS AND METHODS: Cross-sectional, descriptive and analytical, monocentric, full collection. 647 subjects, both genders, admitted with HIF between 01.01.2010 and 12.31.2012, separating them in inhospital deceased and discharged alive. Registered deaths, gender, age, anatomic location, type of trauma, place of occurrence of HIF, time fracture-death, length of hospital stay, percentage of operated, diagnosis associated with HIF, diagnosis of death, comorbidity associated with the diagnosis of death and place of death. Data in orthogeriatric chart, descriptive analysis. RESULTS: IHM = 3.09%. Average age 84 years. The most important diagnoses of death were infections (40%) and thromboembolic disease (15%). 80% presented chronic comorbidity related to the cause of death. There were no significant differences according to age, gender, HIF anatomical location, place of occurrence of the HIF, length of hospital stay. There were significant differences in the number of non-operated, higher in the IHM group (p < 0.000), expected for selection bias. It is desirable to identify early those subjects with HIF who are at high risk for IHM. This, to define conservative management, optimize quality of life and hospital resources.

Características epidemiológicas y clínicas de las fracturas de cadera en adultos mayores en un hospital público chileno: Experience in 647 Chilean patients aged 60 years or more / Hip fracture

Background: Hip fractures (HFx) are an important geriatric syndrome, with a high incidence in developing countries. Aim: To describe characteristics of a group of Chilean patients with HFx. Patients and Methods: In a cross-sectional study we included patients aged 60 years or more with a HF admitted to an orthopedic service along three years. Age, incidence, location, seasonality, hospital stay, time between HFx and surgery, mortality, prior treatment for osteoporosis, anatomical location, etiology and type of surgery were evaluated. Results: We reviewed 647 patients with a median age of 81 years (76% women). The calculated incidence of hip fracture for people aged ≥ 65 years was 177/100,000. Sixty six percent of fractures were extracapsular. Mean hospital stay was 17 days and the mean lapse between the fracture and surgery was 19 days. Eighty four percent of patients had osteoporosis and only 5% were receiving treatment. Eighty three percent of patients were operated. Osteosynthesis was mainly used for extracapsular fractures and arthroplasty for intracapsular lesions. Intracapsular HFx tended to occur more commonly during warm seasons (Odds ratio = 1.534). Mortality at one year was 24%. It was higher among non-operated patients in whom the proportion of males and number of comorbidities were significantly higher. Conclusions: A high proportion of patients with HFx have osteoporosis albeit a reduced number is receiving treatment. Non-operated patients had a higher risk profile and higher mortality.
