Objective of this study was to identify new risk factors and to confirm previously reported risk factors associated with 30-day mortality after hip fracture surgery. Patients and methods: A prospective hip fracture database was used to obtain data. In total, 3523 patients who underwent hip fracture surgery between 2011 and 2021 were included. Univariable and multivariable logistic regression was used to screen and identify candidate risk factors. Twenty-seven baseline factors and 16 peri-operative factors were included in the univariable analysis and 28 of those factors were included in multivariable analysis. Results: 8.6% of the patients who underwent hip fracture surgery died within 30 days after surgery. Prognostic factors associated with 30-day mortality after hip fracture surgery were as follows: age 90– 100 years (OR = 4.7, 95% CI: 1.07– 19.98, p = 0.041) and above 100 years (OR = 11.3, 95% CI: 1.28– 100.26, p = 0.029), male gender (OR = 2.6, 95% CI: 1.97– 3.33, p < 0.001), American Society of Anesthesiologists (ASA) 3 and ASA 4 (OR = 2.1, 95% CI: 1.44– 3.14, p < 0.001), medical history of dementia (OR = 1.7, 95% CI: 1.25– 2.36, p = 0.001), decreased albumin level (OR = 0.94, 95% CI: 0.92– 0.97, p < 0.001), decreased glomerular filtration rate (GFR) (OR = 0.98, 95% CI: 0.98– 0.99, p < 0.001), residential status of nursing home (OR = 2.1, 95% CI: 1.44– 2.87, p < 0.001), higher Katz Index of Independence in Activities of Daily Living (KATZ-ADL) score (OR = 1.1, 95% CI: 1.01– 1.16, p=0.018) and postoperative pneumonia (OR = 2.4, 95% CI: 1.72– 3.38, p < 0.001). Conclusion: A high mortality rate in patients after acute hip fracture surgery is known. Factors that are associated with an increased mortality are age above 90 years, male gender, ASA 3 and ASA 4, medical history of dementia, decreased albumin, decreased GFR, residential status of nursing home, higher KATZ-ADL score and postoperative pneumonia.

Purpose: The primary aim of this study was to identify risk factors for delirium after hip fracture surgery. The secondary purpose of this study was to verify peri-operative clinical outcomes, adverse events and mortality rates in delirium patients after hip fracture surgery. Patients and Methods: A prospective hip fracture database was used to obtain data. In total, 2051 patients older than 70 years undergoing a hip fracture surgery between 01– 01-2018 and 01– 01-2021 were included. A delirium was diagnosed by a geriatrician based on the DSM-V criteria. Results: The results showed that 16% developed a delirium during hospital admission. Multivariable analysis showed that male gender (OR: 1.99, p< 0.001), age (OR: 1.06, p< 0.001), dementia (OR: 1.66, p=0.001), Parkinson's disease (OR: 2.32, p=0.001), Δhaemoglobin loss (OR: 1.19, p=0.022), pneumonia (OR: 3.86, p< 0.001), urinary tract infection (UTI) (OR: 1.97, p=0.001) and wound infection (OR: 3.02, p=0.007) were significant independent prognostic risk factors for the development of a delirium after hip surgery. The median length in-hospital stay was longer in patients with a delirium (9 days) vs patients without a delirium (6 days) (p< 0.001). The 30-day mortality was 7% (with delirium 16% vs with no delirium 6% (p< 0.001)). Conclusion: Significant independent prognostic factors associated with delirium after hip surgery were male gender, age, dementia, Parkinson's disease, Δhaemoglobin loss, pneumonia, UTI and wound infection.

Introduction: The Nottingham Hip Fracture Score (NHFS) was developed to predict 30-day mortality for patients with hip fracture. This study aimed to validate the NHFS in a cohort with sufficient statistical power. Methods: Data were extracted from a prospective hip-fracture database (FAMMI). Patients were included between January 1, 2018 and January 11, 2021. All consecutively admitted patients ≥ 18 years of age with a hip fracture (ie, femoral neck fracture, intertrochanteric fracture, and subtrochanteric fracture) were included. Mann–Whitney's U values were calculated to find potential miscalibration of the NHFS formula. Discrimination evaluation was performed using the concordance statistic as an equivalent to area under the receiver-operating curve. Results: In total, 2,458 patients were included. Mean age was 80± 12 years, and 66% were women (n=1,631). Median NHFS was 5 (4– 6) and overall 30-day mortality 7.9% (n=195). Overall goodness of fit was tested with Pearson's ?2 (11.8, df 10; P=0.297). No statistically significant signs of miscalibration were found (Mann–Whitney U, P=0.08). Discrimination was tested with area under the receiver- operating curve, which was 72.1% (95% CI 68.7%– 75.4%). However, observed 30-day mortality in our population of hip-fracture patients was slightly higher than the NHFS prediction. Conclusion: The NHFS seemed to predict 30-day mortality with reasonable accuracy for patients with a hip fracture in a population within the Netherlands. [ABSTRACT FROM AUTHOR]

Background: The primary aim of the present study was to verify the potential risk factors for developing a delirium after hip fracture surgery. The secondary aim of this study was to examine the related clinical outcomes after a delirium developed post-hip fracture surgery. Patients and methods: Data were extracted from a prospective hip fracture database and completed by retrospective review of the hospital records. A total of 463 patients undergoing hip fracture (hip hemiarthroplasty) surgery in a level II trauma teaching hospital between January 2011 and May 2016 were included. Delirium was measured using the Delirium Observation Screening Scale, the confusion assessment method, and an observatory judgment by geriatric medicine specialists. Results: The results showed that 26% of the patients (n=121) developed a delirium during hospital stay with a median duration during admission of 5 days (IQR 3–7). The multivariable model showed that the development of delirium was significantly explained by dementia (OR 2.75, P=0.001), age (OR 1.06, P=0.005), and an infection during admission (pneumonia, deep surgical site infection, or urinary tract infection) (OR 1.23, P=0.046). After 1 year of follow-up, patients who developed delirium after hip fracture surgery were significantly more discharged to (semi-independent) nursing homes (P<0.001) and had a significantly higher mortality rate (P<0.001) compared to patients without delirium after hip fracture surgery. Conclusions: The results showed that 26% of the patients undergoing hip fracture surgery developed a delirium. The risk factors including age, dementia, and infection during admission significantly predicted the development of the delirium. No association was confirmed between delirium and time of admission or time to surgery. The development of delirium after hip fracture surgery was subsequently found to be a significant predictor of admission to a nursing home and mortality after 1 year. [ABSTRACT FROM AUTHOR]
