[Multicenter cross-sectional study on the prevalence of delirium in orthogeriatric units: «DELFRA 24 study¼ protocol]. / Estudio transversal multicéntrico sobre la prevalencia de delirium en unidades de ortogeriatría: protocolo de «Estudio DELFRA 24¼.

INTRODUCTION: Delirium is the most common perioperative complication in older adults with hip fracture (HF), leading to a catastrophic impact on their functional recovery and cognitive status. Currently, the true prevalence of this syndrome is unknown as its detection and management are not standardized in clinical practice. METHODS: A multicenter observational cross-sectional study will be conducted nationwide, involving different orthogeriatric units in Spain. The prevalence of delirium will be assessed using the 4AT scale, along with its characteristics and its relationship with other geriatric syndromes, sociodemographic variables, surgical characteristics, and laboratory parameters. RESULTS: Data collection is scheduled to take place on World Delirium Day (Wednesday, March 13, 2024), and therefore, the results are expected during the second or third quarter of 2024. CONCLUSIONS: Understanding the real prevalence and characteristics of delirium in older adults with HF could contribute to the development of strategies for its detection and management, reducing the impact of its consequences.

Predictive factors of osteoporotic hip fracture in octogenarians.

OBJECTIVE: This study aims to identify the risk factors associated with osteoporotic hip fractures in octogenarians and seeks to refine primary prevention strategies for these fractures. MATERIAL AND METHODS: We conducted a case-control study involving individuals aged 79 years and older with hip fractures, comparing them to age- and sex-matched controls without a history of hip fractures. We collected epidemiological, clinical, anthropometric, and analytical factors. We evaluated the presence of osteoporosis using bone densitometry. We defined sarcopenia according the European Working Group on Sarcopenia in Older People criteria (EWGSOP2). RESULTS: Ninety-five patients per group were analyzed, with a mean age of 82 years, of which 74% were women. The multivariate analysis included statistically significant factors found in the univariate analysis (p < 0.05). These factors included the Barthel Index, nutritional assessment using the CONUT tool, folic acid, vitamin D deficiency, presence of previous fractures, loss of visual acuity, bicipital circumference, sarcopenia, and osteoporosis (densitometry in the neck of the femur). The Nutritional state (OR: 0.08 [0.01-0.61]), the folic acid levels (OR 0.32 [0.1-1]), and a loss of visual acuity (OR 33.16 [2.91-377.87]) were the independent risk factors associated with hip fracture. CONCLUSIONS: The assessment of nutritional status in elderly patients, coupled with a comprehensive geriatric assessment, represents easily reproducible and cost-effective tools. These tools can effectively aid in identifying individuals at risk of hip fractures, thereby contributing to more targeted and efficient preventive measures.

[Oral nutritional supplementation as an intervention in patients with hip fracture]. / Suplementación nutricional oral como intervención en pacientes con fractura de cadera.

Introduction: Fragility hip fracture (FHR) is an increasingly prevalent pathology in industrialized countries, with high social and health costs. Malnutrition or the risk of malnutrition in the population with FHR is too common and negatively impacts the clinical course, the rehabilitation process, and the resulting quality of life after discharge. Technological advances applied to the diagnosis of the nutritional status of patients with FHR contribute to achieving an early intervention of malnutrition and reducing associated morbidity and mortality. Oral nutritional supplementation with a high energy and protein intake could be a safe and effective action to improve the prognosis of patients with FHR, but further research is required to confirm this.

Introducción: La fractura de cadera por fragilidad (FCF) es una patología cada vez más prevalente en países industrializados, con un alto coste social y sanitario. La desnutrición o el riesgo de desnutrición en población con FCF es demasiado común y tiene un impacto negativo en la evolución clínica, en el proceso de rehabilitación y en la calidad de vida resultante tras el alta sanitaria. Los avances tecnológicos aplicados al diagnóstico del estado nutricional del paciente con FCF contribuyen a lograr una intervención precoz de la desnutrición y a reducir la morbimortalidad asociada. La suplementación nutricional oral de alto aporte energético y proteico podría ser una actuación segura y eficaz para mejorar el pronóstico del paciente con FCF, pero se requiere de más investigación que lo confirme.

Demographic, functional and clinical characteristics in hip fracture patients according to mental status of the Spanish National Hip Fracture Registry.

OBJECTIVE: To describe the differences according to mental status at admission on the care process and 30-day outcomes in hip fracture patients, mainly regarding the use of rehabilitation resources and anti-osteoporotic medication, by analysing data from the Spanish National Hip Fracture Registry (RNFC, "Registro Nacional de Fracturas de Cadera" in Spanish). METHODS: We analysed prospectively collected data from a cohort of patients admitted participating in the Spanish National Hip Fracture Registry (RNFC) in 76 Spanish hospitals between 2017 and 2019. We classified participants using Short Portable Mental Status Questionnaire (SPMSQ), defining two groups: patients with ≤2 SPMSQ score and patients with >2 SPMSQ score. RESULTS: Of 21,254 patients was recorded SPMSQ in 17,242 patients, 9052 were >2 SPMSQ score (52.6%). These were older (87.7 vs. 85.3 years; p<0.001), had worse mobility (no-independent walking ability 26.0% vs. 4.5%; p<0.001) and were more likely to be living in nursing homes (35.3% vs. 9.6%; p<0.001). They were more likely to be treated nonoperatively (3.8% vs. 1.5%; p>0.001), less early mobilisation (57.5% vs. 68.9%; p<0.001) and suffered higher in-hospital mortality (5.2% vs. 2.7%; p<0.001). At discharge, they received less anti-osteoporotic medication (37.9% vs. 48.9%; p<0.001) and returned home less often (29.8%% vs. 51.2%; p<0.001). One month after fracture, patients with >2 SPMSQ score had poorer mobility (no-independent walking ability 44.4% vs. 24.9%; p<0.001) and were newly institutionalised in a nursing home more (12.6% vs. 12.0%; p<0.001) and were more likely to die by one-month post-fracture (9.5% vs. 4.6%; p<0.001). CONCLUSION: RNFC patients with >2 SPMSQ score were more vulnerable and had poorer outcomes than patients with ≤2 SPMSQ score, suggesting that they need specialised care in-hospital and in the recovery phase.

Analysis of machine learning algorithmic models for the prediction of vital status at six months after hip fracture in patients older than 74 years. / Análisis de modelos algorítmicos de aprendizaje automático para la predicción del estado vital a los seis meses tras fractura de cadera en pacientes mayores de 74 años.

BACKGROUND AND OBJECTIVE: The objective is to develop a model that predicts vital status six months after fracture as accurately as possible. For this purpose we will use five different data sources obtained through the National Hip Fracture Registry, the Health Management Unit and the Economic Management Department. MATERIAL AND METHODS: The study population is a cohort of patients over 74 years of age who suffered a hip fracture between May 2020 and December 2022. A warehouse is created from five different data sources with the necessary variables. An analysis of missing values and outliers as well as unbalanced classes of the target variable («vital status¼) is performed. Fourteen different algorithmic models are trained with the training. The model with the best performance is selected and a fine tuning is performed. Finally, the performance of the selected model is analyzed with test data. RESULTS: A data warehouse is created with 502 patients and 144 variables. The best performing model is Linear Regression. Sixteen of the 24 cases of deceased patients are classified as live, and 14 live patients are classified as deceased. A sensitivity of 31%, an accuracy of 34% and an area under the curve of 0.65 is achieved. CONCLUSIONS: We have not been able to generate a model for the prediction of six-month survival in the current cohort. However, we believe that the method used for the generation of algorithms based on machine learning can serve as a reference for future works.

Clinical and subclinical arteriosclerotic disease in octagenarians with hip fracture. A case-control study.

BACKGROUND AND OBJECTIVES: Evaluate clinical and subclinical arteriosclerotic disease in older patients with hip fracture compared with patients without fracture in order to increase knowledge about the relation between both diseases in older individuals. PATIENTS AND METHODS: Age- and sex-matched case-control study of octogenarians with and without recent hip fracture. Vascular risk factors, subclinical vascular diseases (assessed by carotid plaques, carotid intima media thickness and arterial stiffness) as well as cardiovascular diseases were analyzed. Univariate and multivariate logistic models were used to estimate odds ratios (OR) with their 95% confidence intervals (CI) to assess the association of the arteriosclerosis and hip fracture. RESULTS: We analyzed 95 patients per group with a median age of 82 [79-87] years of whom 77.9% were female. Patients in both groups have elevated rates of vascular disease (25%) without differences between them. Patients with hip fracture had higher subclinical arteriosclerotic alterations with higher percentage of carotid plaques (OR 3.25 [1.06-9.97]) compared with the control group. CONCLUSIONS: Older patients with hip fracture had significantly higher presence of subclinical alterations but not increase on rate of cardiovascular arteriosclerotic disease compared with those without hip fracture.

Short versus long intramedullary nails for intertrochanteric hip fracture: Meta-analysis. / [Artículo traducido] Clavo corto versus clavo largo en la fractura intertrocantérica de cadera: metaanálisis.

OBJECTIVE: To compare short versus long intramedullary nails for intertrochanteric hip fractures in terms of efficacy and safety. METHODS: We included cohort studies and randomized clinical trials. The methodological quality of the studies was assessed by the Newcastle-Ottawa Scale. The meta-analysis was performed using the Review Manager 5.4. Heterogeneity was checked with the I2 test. A fixed effects model was adopted if there was no heterogeneity. RESULTS: Twelve studies were included. The reoperations rate was lower in the short nail group (OR: 0.58, 95%CI: 0.38-0.88) and there were no differences regarding the peri-implant fracture rate (OR: 1.77, 95%CI: 0.68-4.60). Surgery time and blood loss was significantly higher in the long nail group (MD: -12.44, 95%CI: -14.60 -10.28) (MD: -19.36, 95%CI: -27.24 -11.48). There were no differences in functional outcomes. CONCLUSIONS: The long nail showed a higher reoperation rate, blood loss and surgery time compared to the short nail. LEVEL OF EVIDENCE: III.

Concurrent uper limb and hip fracture in the elderly: experience at our centre. / Fracturas concomitantes de miembro superior y cadera en pacientes mayores de 65 años: experiencia en nuestro centro.

INTRODUCTION: The incidence of hip fracture in the elderly is on the rise, occasionally accompanied by concurrent upper limb fractures. Our investigation aims to determine whether these patients experience poorer functional outcomes, prolonged hospitalization, or higher mortality rates when compared to those with isolated hip fracture. MATERIAL AND METHODS: We retrospectively reviewed 1,088 elderly patients admitted to our centre with hip fracture between January 2017 and March 2020. We recorded the presence of concomitant fractures and their treatment. We analyzed the duration of hospital stay, in-hospital mortality and function. RESULTS: We identified 63 patients with concomitant upper limb fracture (5.6%). Among them, 93.7% were women, and the average age was 86.4 years. 80.9% of the upper limb fractures were distal radius or proximal humerus. Patients with concomitant fracture had increased length of stay (mean, 19.6 vs, 12.8, p=0.002), decreased proportion of patients returning to their own home at discharge (23.6% vs, 26.3%, p=0.042) and increased in-hospital mortality rate (9.5% vs, 5.9%, p=0.003). CONCLUSIONS: Patients with concomitant upper limb fracture require a longer length of stay and exhibit an elevated in-hospital mortality rate. Furthermore, this condition is associated with a reduced short-term functional recovery, thereby decreasing the chances of the patient returning home upon hospital discharge.

Surgical treatment of non-displaced subcapital hip fracture: Femoral Neck System vs. cannulated screws. Comparative study. / Tratamiento quirúrgico de fractura subcapital de cadera no desplazada: Femoral Neck System vs. tornillos canulados. Estudio comparativo.

OBJECTIVE: The objective of this study is to compare the outcomes of using the Femoral Neck System (FNS) (DePuy Synthes®) versus the use of cannulated screws (CS) in the surgical treatment of non-displaced subcapital hip fractures. MATERIALS AND METHODS: A retrospective cohort study was conducted on non-displaced subcapital hip fractures treated with CS or FNS between 2020 and 2023, with a minimum follow-up of one year. A total of 28 patients were included, 14 treated with CS and 14 with FNS. Demographic, radiological, clinical, and functional variables were analyzed. RESULTS: In the CS group, 64% were male, with a mean age of 66.5 years (SD 14.9) and an average follow-up of 22 months (range, 12-36 months). In the FNS group, 57% were male, with a median age of 60.8 years (SD 13.78) and an average follow-up of 16 months (range, 12-24 months). Regarding functional outcomes, no significant differences were found between FNS and CS in the Harris scale: 94.21±11.55 for FNS and 96.50±6.9 for CS (p=0.618). The total postoperative complications (FNS/CS) were 7.1% versus 43%, and implant failure with conversion to total hip replacement was 0% versus 43%, both significantly higher in the CS group (p=0.047; p=0.016, respectively). The FNS also presented a lower rate of avascular necrosis (0% versus 11.1%, p=0.391) and nonunion (0% versus 20%, p=0.163), although these differences did not reach statistical significance. CONCLUSIONS: Although both treatment methods, cannulated screws and the FNS, showed similar short-term functional outcomes in the management of undisplaced subcapital femoral fractures, the FNS demonstrated a significantly lower rate of complications and reoperations. These results suggest that the FNS could be considered a safer and more effective option compared to cannulated screws.

[Impact of the COVID-19 pandemic and the strict population confinement on hip fracture incidence in Spain: A systematic review]. / Impacto de la pandemia por COVID-19 y el confinamiento estricto de la población en la incidencia de fractura de cadera en España. Una revisión sistemática.

BACKGROUND AND OBJECTIVE: During the COVID-19 pandemic, a strict population confinement was decreed in Spain. In a situation of health crisis and health system saturation, knowledge of pathologies whose treatment cannot be delayed is of great importance for the correct management of resources and processes. The objective was to determine the influence of the COVID-19 pandemic and the strict population confinement on hip fracture incidence in Spain. MATERIAL AND METHOD: Systematic review following the PRISMA guidelines. Search in Pubmed and Chocrane Library on 11/11/2022: hip fracture and COVID-19 and Spain. RESULTS: Six studies met the inclusion criteria, 50% showed a decrease in the hip fractures incidence during strict population confinement (all in Comunidad de Madrid hospitals), and in the other 50% there were no differences (all in other region hospitals). It was constant that hip fractures, either did not decrease, or decreased much less than the rest of fractures during the period of strict population confinement, increasing their relative number with respect to the total admissions in orthopedic surgery and traumatology. CONCLUSIONS: The behavior of the hip fractures number during the strict population confinement decreed by the COVID-19 pandemic has not been symmetrical in all regions. To design and implement contingency plans in the event of a pandemic situation, these data must be taken into account in order to properly plan material and human resources.

Pilot study to determine the association between gut microbiota and fragility hip fracture. / Estudio piloto para determinar la asociación entre la microbiota intestinal y la fractura de cadera por fragilidad.

INTRODUCTION: Hip fractures are the most common cause of hospital admission to orthopaedic departments in Europe and they generate a major health problem. Therefore, it is of great interest to identify additional risk factors that will help us to better understand the pathophysiology of these fractures and improve our preventive capacity. There is sufficient data to support the theory of modulation of bone mass by gut microbiota (osteomicrobiology); however, there is a lack of human clinical studies directly linking microbiota to hip fracture risk. MATERIAL AND METHODS: Observational, analytical, case-control study. The sample consisted of 50 patients and it was distributed as follows: 25 elderly patients with fragility hip fracture and 25 subjects without fracture. The intestinal microbiota was determined by DNA extraction from stool samples and 16S ribosomal DNA sequencing after generation of gene libraries. RESULTS: Alpha diversity revealed an elevation of the estimators for the taxonomic class level in the hip fracture group. The orders Bacteroidales, Oscillospirales, Lachnospirales, Peptostreptococcales-Tissierellales and Enterobacterales were the dominant orders in both groups. In patients with fracture, a significant percentage increase in the orders Bacteroidales (p<.001) and Peptostreptococcales-Tissierellales (p<.005) was observed, as well as a decrease in the orders Lachnospirales (p<.001) compared to controls. CONCLUSIONS: This study has found an association between a specific microbiota in elderly patients with fragility hip fracture. These findings open the door to new strategies to prevent hip fractures. Modification of the microbiota through probiotics may prove to be an effective method to reduce the risk of hip fracture.

One-year mortality and associated factors in patients undergoing surgery for hip fracture. / Mortalidad al año y factores asociados en pacientes llevados a cirugía por fractura de cadera.

INTRODUCTION: Hip fractures are very common injuries in elderly patients and are associated with increased mortality. OBJECTIVE: To identify the factors associated with mortality in patients after one year of being operated for hip fracture in an Orthogeriatric Program. METHODS: We design an observational analytical study in subjects older than 65 years admitted to the Hospital Universitario San Ignacio for hip fracture who were treated in the Orthogeriatrics Program. Telephone follow-up was performed one year after admission. Data were analyzed using a univariate logistic regression model and a multivariate logistic regression model was applied to control the effect of the other variables. RESULTS: Mortality was 17.82%, functional impairment was 50.91%, and institutionalization was 13.9%. The factors associated with mortality were moderate dependence (OR=3.56, 95% CI=1.17-10.84, p=0.025), malnutrition (OR=3.42, 95% CI=1.06-11.04, p=0.039), in-hospital complications (OR=2.80, 95% CI=1.11-7.04, p=0.028), and older age (OR=1.09, 95% CI=1.03-1.15, p=0.002). The factor associated with functional impairment was a greater dependence at admission (OR=2.05, 95% CI=1.02-4.10, p=0.041), and with institutionalization was a lower Barthel index score at admission (OR=0.96, 95% CI=0.94-0.98, p=0.001). CONCLUSIONS: Our results shows that the factors associated with mortality one year after hip fracture surgery were: moderate dependence, malnutrition, in-hospital complications and advanced age. Having previous functional dependence is directly related to greater functional loss and institutionalization.

[Translated article] Has the COVID-19 lockdown influenced the mortality of hip fracture? Analysis of one-year mortality.

INTRODUCTION AND OBJECTIVES: The main objective of this study is to analyse the one-year mortality in patients with intracapsular hip fracture who were admitted during severe social confinement in the first months of the COVID-19 lockdown and compare it with previous years. MATERIAL AND METHODS: Retrospective observational study in which a cohort from March 14 to June 21, 2020 (pandemic group, n=62) was compared with a control cohort on the same dates in the years 2017, 2018 and 2019 (control group, n=172). Thirty-day-mortality and one-year-mortality, orthopaedic complications, ASA grade, comorbidities, diagnosis and treatment, time to surgery and mean stay were measured. RESULTS: No significant differences were found in 30-day mortality (p=0.156; 9.7% compared to 4.7%) or in one-year mortality (p=0.47) between the pandemic group (21%) and the control one (16.9%). A decrease in surgical delay and mean stay was observed in the pandemic group, although without statistical significance. CONCLUSION: The State of Alarm modified the distribution of the type of hip fracture with a predominance of intracapsular fracture. Maintaining the same hospital management as prior to the pandemic period made it possible not to increase 30-day mortality and one-year mortality in patients with intracapsular hip fracture.

[Functional recovery units state in orthogeriatrics according to data from the National Registry of Hip Fracture]. / Situación de las Unidades de Recuperación Funcional en ortogeriatría según datos del Registro Nacional de Fractura de Cadera.

INTRODUCTION: The National Registry of Hip Fractures (RNFC) facilitates knowledge of hip fracture process in Spain to clinicians and managers and is useful to the reduction of the results variability, including the destination at discharge after the hip fracture. OBJECTIVE: The aim of this study was to describe functional recovery units (URFs) use for patients with hip fracture included in the RNFC and to compare the results of the different autonomous communities (AC). MATERIAL AND METHODS: An observational, prospective and multicenter study of several hospitals in Spain. Data from a RNFC cohort of patients admitted with hip fracture between 2017 and 2022 were analyzed, focusing on the location at discharge of the patients, specifically on transfer to the URF. RESULTS: 52,215 patients from 105 hospitals were analyzed, 9540 patients (18.1%) were transferred to URF upon discharge and 4595 (8.8%) remained in these units 30 days later, with a variable distribution between the different AC (0-49%) and variability of results in patients not recovering ambulation at 30 days (12.2-41.9%). CONCLUSIONS: There is in orthogeriatric patient an unequal availability and use of URFs between different autonomous communities. The study of the usefulness of this resource can be of great value for decision-making in health policies.

Prevalence of sarcopenia in patients older than 75 years admitted for hip fracture.

BACKGROUND: Hip fracture in the population aged 75 years and older is one of the most disabling pathologies. Likewise, disease related malnutrition (DRM) and sarcopenia are two frequent diagnoses in this age group, whose prevalence may be increased in patients with hip fracture. AIMS: To determine the prevalence of malnutrition and/or sarcopenia in patients admitted for hip fracture and evaluate the existence of malnutrition related to disease and sarcopenia, and the differences between the sarcopenic and non-sarcopenic group. METHODS: 186 patients aged 75 years or over, hospitalised for hip fracture from March 2018 to June 2019 were included. Demographic, nutritional and biochemical variables were collected. Nutritional screening was carried out with the Mini-Nutritional Assessment (MNA), the presence of DRM was established with The Global Leadership Initiative on Malnutrition (GLIM) criteria. For sarcopenia screening, the Strength, Assistance with walking, Rising from a chair, Climbing stairs and Falls (SARC-F) was used and the diagnosis of sarcopenia was made using the criteria from the European Working Group on Sarcopenia in Older People (EWGSOP) reviewed in 2019 (EWGSOP2). Muscle strength was determined by hand-grip strength, body composition by measurement of bioelectrical impedance. RESULTS: The mean age was 86.2 years, most of the patients were women (81.7%). 37.1% of patients were at nutritional risk (MNA 17-23.5) and 16.7% were malnourished (MNA < 17). 72.4% of women and 79.4% of men, were diagnosed with DRM. 77.6% of the women and 73.5% of the men had low muscle strength. The appendicular muscle mass index was below the cut-off points for sarcopenia in 72.4% of the women and 79.4% of the men. Patients with sarcopenia had a lower body mass index, older age, poorer previous functional status and higher disease burden. The relationship between weight loss and hand grip strength (HGS) was significant (p = 0.007). CONCLUSIONS: 53.8% of patients admitted for hip fracture present malnutrition or are at risk after screening with MNA. Sarcopenia and DRM affects at least three out of four patients older than 75 years admitted for hip fracture. Older age, worse functional status, lower body mass index and high number of comorbidities, are associated with these two entities. There is a relationship between DRM and sarcopenia.

Benefits of analgesic blocks, PENG block (PEricapsular Nerve Group), in fast recovery after hip surgery. / Beneficios de los bloqueos analgésicos, PENG (PEricapsular Nerve Group), en la recuperación precoz tras la cirugía de cadera.

INTRODUCTION: Hip fracture is a frequent orthopedic emergency which associates high morbidity and mortality and intense pain. Locoregional analgo-anesthetic techniques, both central and peripheral, occupy a preferential place in the multimodal therapeutic arsenal. Recently, a new regional blockade has emerged, the pericapsular block or PENG block (PEricapsular Nerve Group). The objective is to evaluate in patients with hip fracture, the antinociceptive efficacy of the preoperative PENG block, residual motor block and time for postoperative functional recovery. METHOD AND MATERIALS: Prospective descriptive observational study with patients going to have total hip arthroplasty. PENG block was performed before surgery. Pain was assessed with the Visual Numerical Scale (VNS) before the blockade, 30min later, in the immediate postoperative period and 24h after the intervention. Motor block according to the Bromage scale and time needed for assisted walking were also evaluated. RESULTS: PENG block provided effective analgesia in all patients, with a decrease in at least 3 points on the VNS at every step in which it was evaluated. The average difference between pain before and after the block was 7.5 points on the VNS. It allowed the transfer and placement of the patient without hemodynamic alteration, exacerbation of pain or other complications. CONCLUSIONS: PENG block is an effective and safe regional analgesic technique for patients with hip fracture. It allows mobilization and placement before surgery without pain exacerbation, promoting early mobility and rehabilitation.

Lower mortality and readmission in patients with few comorbidities who underwent hip fracture surgery and were discharged early. / Menor mortalidad y reingreso en pacientes con pocas comorbilidades intervenidos de fractura de cadera y con alta precoz.

INTRODUCTION: Preoperative delay in patients with hip fracture surgery (HF) has been associated with poorer outcomes; however, the optimal timing of discharge from hospital after surgery has been little studied. The aim of this study was to determine mortality and readmission outcomes in HF patients with and without early hospital discharge. MATERIAL AND METHODS: A retrospective observational study was conducted selecting 607 patients over 65years of age with HF intervened between January 2015 and December 2019, from which 164 patients with fewer comorbidities and ASA ≤II were included for analysis and divided according to their postoperative hospital stay into early discharge or stay ≤4 days (n=115), and non-early or post-operative stay >4days (n=49). Demographic characteristics; fracture and surgical-related characteristics; 30-day and one-year postoperative mortality rates; 30-day postoperative hospital readmission rate; and medical or surgical cause were recorded. RESULTS: In the early discharge group all outcomes were better compared to the non-early discharge group: lower 30-day (0.9% vs 4.1%, P=.16) and 1-year postoperative (4.3% vs 16.3%, P=.009) mortality rates, as well as a lower rate of hospital readmission for medical reasons (7.8% vs 16.3%, P=.037). CONCLUSIONS: In the present study, the early discharge group obtained better results 30-day and 1-year postoperative mortality indicators, as well as readmission for medical reasons.
