Preoperative Serum Calcium Level Predicts Postoperative Mortality in Older Adult Patients with Hip Fracture: A Prospective Cohort Study of 2333 Patients. J Am Med Dir Assoc 2024; 25:655-660. [PMID: 37660723 DOI: 10.1016/j.jamda.2023.08.004] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/30/2023] [Revised: 08/02/2023] [Accepted: 08/03/2023] [Indexed: 09/05/2023]
Abstract
OBJECTIVES Hip fractures are a significant cause of mortality among older adults. However, predictive markers for an unfavorable prognosis are still lacking. Serum calcium is an essential element in several biochemical reactions in the body. This study investigated the role of the preoperative serum calcium level as a prognostic parameter for postoperative mortality in older adult patients with hip fractures. DESIGN We conducted a prospective cohort study at the trauma center in our hospital, from January 1, 2015, to September 30, 2019. A total of 2333 older patients with hip fractures were recruited. This prospective cohort study was conducted in accordance with the criteria of STROCSS. SETTING AND PARTICIPANTS Older adult patients with hip fractures were screened between January 2015 and September 2019 at the trauma center of our hospital. METHODS Demographic and clinical characteristics of the patients were collected. Linear and nonlinear multivariate Cox regression models were used to identify the association between preoperative serum calcium level and all-cause mortality. All analyses were performed using EmpowerStats and the R software. RESULTS A total of 2333 older adult patients with hip fractures were included in the study. The mean follow-up was 37.5 months. Overall, 770 patients (33%) died of all causes. The preoperative serum calcium concentrations were 2.18 ± 0.13 mmol/L. Linear multivariate Cox regression models showed that preoperative serum calcium levels were associated with mortality [hazard ratio (HR) 0.37, 95% CI 0.21-0.67; P = .0009] after adjusting for confounders. However, the linear association was unstable, and nonlinearity was identified. A preoperative serum calcium level of 2.3 mmol/L was an inflection point for prediction. When the preoperative serum calcium concentration was below 2.3 mmol/L, serum calcium concentration increased by 1 mmol/L, and mortality risk decreased by 77% (HR 0.23, 95% CI 0.13-0.43, P < .0001). In contrast, when the preoperative serum calcium concentration was more significant than 2.3 mmol/L, the mortality risk increased with serum calcium concentration (HR 6.27, 95% CI 1.65-23.74, P = .0069). CONCLUSIONS AND IMPLICATIONS The preoperative serum calcium level is nonlinearly associated with mortality in older adults with hip fractures, with a U-shaped association, and could be used as a potential predictor of prognosis.

Survival and Results after Resection and Reconstruction with Megaprosthesis at the Hip in Octogenarians. J Clin Med 2023; 12:7740. [PMID: 38137808 PMCID: PMC10743573 DOI: 10.3390/jcm12247740] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/20/2023] [Revised: 12/09/2023] [Accepted: 12/12/2023] [Indexed: 12/24/2023] Open
Abstract
Few data are available about results after procedures of resection and megaprosthesis at the hip in very elderly patients. The aim of our study was to ascertain survival and complications in patients aged 80 or older undergoing these major orthopedic procedures. A consecutive series of 27 procedures in 26 patients aged 80-93 years was evaluated. In total, 15 procedures were performed due to oncological diseases, 6 were performed following joint arthroplasty failures or periprosthetic fractures, and 6 were performed after trauma or trauma sequelae. Survival of the patients ranged from 0 to 122 months. Overall survival was 56% at 3 years, 24% at 5 years, and 16% at 8 years. An early postoperative death during the first 3 months occurred in five patients (18.5%). The only preoperative parameter negatively affecting survival was preoperative hemoglobin lower than 11 g/dL. Local complications were similar to reported rates in all-age patients' series. In our experience, resection and megaprosthetic reconstruction can also be a valid choice in very elderly patients, with 56% of patients living more than two years from surgery and 24% more than five. Nevertheless, early postoperative deaths are frequent. A multidisciplinary evaluation of frailty of the patient must be accomplished, and patients and relatives must be informed about the risks of the procedure.

Abstract
INTRODUCTION Geriatric fractures including distal femur and hip fractures are associated with high mortality rates. Currently, prognostic factors for in-hospital postoperative mortality are not identified. We aimed to evaluate overall in-hospital mortality and related potential risk factors in elderly patients who underwent distal femur fracture surgery. MATERIALS AND METHODS A retrospective cohort study of patients older than 60 years, who underwent distal femur fracture surgery between January 01, 2003, and December 31, 2021, was conducted. A case-control study was conducted to compare two age-matched groups of elderly patients of equivalent ages at a 1:4 ratio. The in-hospital mortality rate was calculated and potential confounders were compared between groups. RESULTS A total of 170 patients were enrolled; five died during hospital stay after undergoing surgery, yielding a 2.94% in-hospital mortality rate. Twenty patients who did not die were included in the control group. Patients' demographics were similar. The case-control comparison showed that the time from injury to surgery, preoperative hemoglobin level, estimated glomerular filtration rate (eGFR), and white blood cell count were significant factors correlated with in-hospital mortality. DISCUSSION The overall in-hospital mortality rate was 2.94%. Significant risk factors for in-hospital mortality included a longer time from injury to surgery, lower preoperative hemoglobin level and eGFR, and higher preoperative white blood cell count. In conclusion, preoperative comprehensive geriatric assessment, including cognitive, nutritional, and frailty status, should also be considered in the elderly fracture care model.

Abstract
PURPOSE Hip fracture surgery is associated with a risk of morbidity and mortality, with admission hemoglobin levels being a significant predictor of mortality risk. The aim of this study is to evaluate the relationship between the preoperative hemoglobin (Hb) levels and mortality in patients who underwent hip fracture surgeries, with the goal of enhancing prognosis prediction and reducing complications within this patient subset. In addition, to assess the characteristics of patients at a higher risk of postoperative mortality. METHODS This retrospective study was conducted at Jordan University Hospital, a single tertiary care and educational center. It included patients with hip fractures who underwent surgical repair at the Department of Orthopedic Surgery and were recruited between December 2019 and February 2022. We examined the relationships between preoperative hemoglobin status and variables such as age at admission, gender, fracture type, surgery type, comorbidities, duration of hospital stay, intensive care unit (ICU) admission, and survival outcomes. RESULTS We included 626 patients; the mean age was 76.27 ± 9.57 years. 3-month and 6-month mortality rates were 11.2% and 14.1%, respectively. The highest mortality was observed in patients aged over 80 years (n = 53/245, 21.6%), and in male patients (n = 53/300, 17.7%). The Hb level upon admission was lower in individuals who died within 6 months compared to those who survived (10.97 ± 2.02 vs. 11.99 ± 2.39, p < 0.001). In multivariate analysis, the independent factors that were statistically significant in the model included gender (OR = 1.867; 95% CI 1.122-3.107, p = 0.016), age (OR = 1.060; 95% CI 1.029-1.092; p < 0.001), hemoglobin level upon admission (OR = 0.827; 95% CI 0.721-0.949; p = 0.007), history of renal disease (OR = 1.958; 95% CI 1.014-3.784; p = 0.045), length of hospital stay (OR = 1.080; 95% CI 1.036-1.126; p < 0.001), and ICU admission (OR = 1.848; 95% CI 1.049-3.257; p = 0.034). CONCLUSION Our study illustrates that low hemoglobin levels, history of renal disease, along with male gender, advanced age, extended hospital stays, and ICU admission were significantly associated with 6-month mortality. Future investigations should consider assessing varying degrees of anemia based on hemoglobin concentrations to provide a more comprehensive understanding of anemia's impact on mortality. This study investigated the relationship between preoperative hemoglobin levels, patient characteristics, and mortality in patients who underwent hip fracture surgeries. The results showed that lower hemoglobin levels, history of renal disease, male gender, advanced age, extended hospital stays, and ICU admission were significant predictors for mortality.

Abstract
Despite the abundance of research on the risk factors for mortality following hip fracture surgery, there has been a dearth of studies on prediction models in this population. The objective of this research was to explore the influencing factors and construct a clinical nomogram to predict one-year postoperative mortality in patients with hip fracture surgeries. Using the Ditmanson Research Database (DRD), we included 2333 subjects, aged ≥ 50 years who underwent hip fracture surgery between October, 2008 and August, 2021. The endpoint was all-cause mortality. A least absolute shrinkage and selection operator (LASSO) derived Cox regression was performed to select the independent predictors of one-year postoperative mortality. A nomogram was built for predicting one-year postoperative mortality. The prognostic performance of nomogram was evaluated. On the basis of tertiary points in a nomogram, the patients were divided into low, middle and high risk groups, and compared by the Kaplan-Meier analysis. Within 1 year after hip fracture surgery, 274 patients (11.74%) died. Variables retained in the final model comprised age, sex, length of stay, RBC transfusions, hemoglobin, platelet, and eGFR. The AUC for one-year mortality predictions were 0.717 (95% CI = 0.685-0.749). The Kaplan-Meier curves were significantly different among the three risk groups (p < 0.001). The nomogram showed good calibration. In summary, we explored the one-year postoperative mortality risk in geriatric patients with a hip fracture and developed a prediction model that could help clinicians identify patients at high risk of postoperative mortality.

Eur Geriatr Med 2023; 14:275-284. [PMID: 36805525 DOI: 10.1007/s41999-023-00759-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/05/2022] [Accepted: 02/08/2023] [Indexed: 02/23/2023]
Abstract
BACKGROUND Hip fracture patients often have a large drop in hemoglobin (Hgb) concentration that is associated with the initial trauma. However, there is no study of a correlation between Hgb concentration at admission and short-term mortality. Thus, we evaluated a possible linear and nonlinear association between Hgb and mortalityfor older patients with hip fracture. METHODS Consecutive older patients who had hip fractures were screened between January 2015 and September 2019. Demographic and clinical characteristics were collected. Linear and nonlinear multivariate Cox regression models were used to identify association between Hgb at admission and mortality. All analyses were performed with EmpowerStats and R software. RESULTS Two thousand five hundred eighty-nine patients were included in the study. There were 849 men and 1740 women. The mean age was 79.6 ± 6.8 years. The mean follow-up was 39.0 months. Nine hundred seven (35.0%) patients died for all-cause reasons. The mean Hgb at admission was 11.07 ± 1.95 g/dL. Linear multivariate Cox regression models showed Hgb at admission was associated with mortality ([Hazard Ratio] HR 0.91, 95% CI 0.87-0.95, P < 0.0001) after adjusting for confounding factors. However, the linear association was unstable, and nonlinearity was found between Hgb at admission and mortality. The Hgb concentration of 9.8 g/dL was an inflection point. A Hgb at admission < 9.8 g/dL was associated with mortality (HR 0.81, 95% CI 0.74-0.89, P < 0.0001), whereas > 9.8 g/dL was not a risk factor for mortality (HR 0.98, 95% CI 0.92-1.04, P = 0.4730). CONCLUSIONS The Hgb concentration at admission was nonlinearly associated with mortality of older patients with hip fracture, and Hgb at admission < 9.8 g/dL was a risk predictor of 3-year mortality.

Abstract
BACKGROUND Anemia has been linked to delayed cerebral ischemia (DCI) and worse outcome in patients with aneurysmal subarachnoid hemorrhage (aSAH). However, the association of hemoglobin (Hb) trend and outcomes is not well studied. We investigated predictors of Hb trend and its association with outcomes in patients with aSAH. Our hypothesis was that a negative Hb trend is associated with poorer outcomes independent of Hb values. METHODS We conducted a retrospective study of a prospectively collected cohort of consecutive patients with aSAH who were admitted to an academic center (2016-2021). We tested the association of Hb trend and values with measures including DCI and poor functional outcome defined as modified Rankin scale 4-6 at 3 months after discharge. Multiple linear regression analysis was used to identify factors associated with Hb difference from admission to discharge. RESULTS We included 310 patients with confirmed aneurysmal etiology (mean age 57 years, SD13.6; 62 % female). Greater Hb decrement from admission to discharge was independently associated with higher likelihood of both DCI (OR 1.28 per 1 g/dl decrease in Hb, 95 % CI 1.08-1.47; p = 0.003) and poor functional outcome (OR 1.27 per 1 g/dl decrease in Hb, 1.03-1.53; p = 0.026) independent of any absolute Hb values. Predictors of Hb decrement from admission to discharge were hospital length of stay, Hunt and Hess grades, female sex and age. CONCLUSION Greater Hb decrement can be associated with higher likelihood of DCI and poor functional outcome in aSAH. More evidence is needed to use Hb trend to guide transfusion threshold in aSAH patients.

Abstract
INTRODUCTION Hip fracture is one of the leading causes of death and disability in the elderly. We analyzed the risk factors of mortality and second fracture within 2 years after hip fracture surgery in elderly Chinese patients. MATERIALS AND METHODS A total of 613 elderly patients after hip fracture surgery were selected, including 181 males and 432 females, and the patients were followed for at least 24 months. Information about patients and surgery was collected from medical records. Information on death, secondary fracture, and postoperative activities of daily living (ADL) was obtained by telephone follow-up. Cox regression was performed to identify risk factors associated with mortality and second fracture, measured by hazard ratio (HR). RESULTS The 1-year and 2-year mortality rates after hip fracture were 13.4% and 20.7%, respectively. The second fracture rate within 2 years was 9.5%. Male gender (HR 1.51, P = 0.035), increased age (HR 1.07, P < 0.001), preoperative hypoalbuminemia (HR 1.79, P = 0.004), preoperative pneumonia (HR 2.60, P = 0.005) and poor ADL (P = 0.048) were independent risk factors for 2-year mortality, while high preoperative hemoglobin (HR 0.98, P = 0.002), high preoperative eGFR (HR 0.99, P = 0.031), high preoperative LVEF (HR 0.92, P = 0.048) were protective factors for 2-year mortality. Poor ADL (P = 0.002) was the independent risk factor for second fracture within 2 years. CONCLUSIONS The 2-year mortality rate and second fracture rate after hip fracture in elderly remained high, which was related to old age and complications exists. Postoperative rehabilitation and improving ADL were very important to reduce mortality and second fracture.

Zhang H, Wu L, Cheng B. Preoperative anemia and deep vein thrombosis in patients with perioperative bone trauma: a cohort study. BMC Musculoskelet Disord 2022; 23:905. [PMID: 36217199 PMCID: PMC9549669 DOI: 10.1186/s12891-022-05869-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/15/2022] [Accepted: 10/04/2022] [Indexed: 11/30/2022] Open
Abstract
Background In current active prevention (including physical and drug prevention), the incidence of perioperative deep vein thrombosis (DVT) of the lower extremities remains high in patients with bone trauma. Risk factors need to be further optimized, and high-risk patients must be identified early. Preoperative comorbidities, especially preoperative anemia, and DVT in patients with perioperative bone trauma are not clear. The purpose of this study was to explore the causal relationship between preoperative anemia and DVT in patients with perioperative bone trauma, and further reduce the incidence of DVT in patients with bone trauma. Objectives To analyze the relationship between preoperative anemia and perioperative DVT in patients with femoral and pelvic fractures and provide a reference for the optimization of risk factors for DVT. Methods The clinical data of 1049 patients with femoral and pelvic fractures who received surgical treatment from May 2018 to June 2021 were retrospectively analyzed. Propensity score matching (PSM) was performed for the covariates of DVT. Modified Poisson regression was used to analyze the relationship between preoperative anemia and DVT. Results After matching 1:1 propensity scores in 1049 patients included in this study, there were 258 patients in the anemic and non-anemic groups. Preoperative anemia was statistically significant for the formation of DVT in patients with perioperative bone trauma (P = 0.000, RR = 1.567 [95% CI 1.217–2.017]). This conclusion remained true after PSM (P = 0.009, RR = 1.500 [95% CI 1.105–2.036]). Preoperative anemia has some predictive value for perioperative DVT, with DVT-associated preoperative anemia thresholds of 125 g/L and area under the receiver operating characteristic curve of 0.5877 (95% CI 0.5345 to 0.6408). On this basis, sensitivity and specificity were 89.2 and 30.3%, respectively, with a Youden index of 0.195. In addition, we conducted an E-value determination of the propensity score; the E-value analysis showed robustness to unmeasured confounding. Conclusions Preoperative anemia is highly correlated with perioperative DVT in patients with bone trauma, which is the cause of perioperative DVT in these patients.

[PMID: 35247357 DOI: 10.1016/j.jamda.2022.01.078] [Citation(s) in RCA: 8] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/05/2021] [Revised: 01/27/2022] [Accepted: 01/27/2022] [Indexed: 12/14/2022]
Abstract
OBJECTIVES We examined whether the comorbidity burden of patients with hip fracture was associated with quality of in-hospital care reflected by fulfillment of process performance measures. DESIGN Population-based cohort study using prospectively collected data from the Danish Multidisciplinary Hip Fracture Registry (DMHFR). SETTING AND PARTICIPANTS Patients aged 65 years or older with an incident hip fracture from 2014 to 2018 registered in the DMHFR (n = 31,443). METHODS Comorbidity was measured using the Charlson Comorbidity Index based on hospital diagnoses. Quality of in-hospital care was defined as fulfillment of eligible process performance measures, including preoperative optimization, early surgery, early mobilization, pain assessment, basic mobility, nutritional risk, need for anti-osteoporotic medication, fall prevention, and a post-discharge rehabilitation program, reflecting guideline-recommended in-hospital care. The outcomes were (1) an all-or-none composite measure defined as fulfillment of all relevant process performance measures, and (2) fulfillment of the individual process performance measures. Using binary regression, we calculated relative risk (RR) for the association between comorbidity level and outcomes. RESULTS The overall proportion of patients with hip fracture who fulfilled the all-or-none measure was 31%. Among patients with no comorbidity, 34% fulfilled the all-or-none measure versus 29% among patients with high comorbidity (Charlson ≥ 3). This corresponds to a 15% lower chance (RR = 0.85, 95% confidence interval 0.81-0.89). Increasing comorbidity was also associated with lower fulfillment of the individual process performance measures. The largest difference was seen for preoperative optimization, early surgery, and early mobilization, where patients with high comorbidity had 6% to 11% lower chance of fulfillment of these process performance measures compared with patients without comorbidity. CONCLUSION AND IMPLICATIONS Increasing level of comorbidity was associated with lower quality of in-hospital care among patients with hip fracture. Our results highlight the need for tailored clinical initiatives to ensure that comorbid patients also benefit from the positive progress in hip fracture care in recent years.

Predictors of 1-year Mortality After Hip Fracture Surgery in Patients with Age 50 years and Above: An Indian Experience. Indian J Orthop 2021; 55:395-401. [PMID: 34306553 PMCID: PMC8275729 DOI: 10.1007/s43465-021-00396-4] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/31/2020] [Accepted: 03/22/2021] [Indexed: 02/04/2023]
Abstract
BACKGROUND Hip fractures are considered as a major cause of mortality worldwide. Even after being the second most populous country in world and facing huge burden of hip fractures, there is scarcity of data from India. For the first time in Indian context, we analysed the predictors of mortality after hip fracture surgery in patients with age 50 years and above. MATERIALS AND METHODS In this prospective cohort study, patients with age ≥ 50 years and having hip fractures presented to our institute from January 2018 through October 2018 were enrolled after meeting including and excluding criteria. Patients were followed-up for minimum 1 year after surgery. Association between 1-year mortality and different affecting variables were analysed. Significant variables were further analysed using logistic regression to find independent predictors. RESULTS Out of 87 patients followed-up for 1 year, 25 patients died within 1 year of surgery. Age > 75 years, road traffic accident as mode of injury, delay in surgery > 48 h, > 2 co-morbidities, haemoglobin level ≤ 10 at the time of admission and osteoporosis are significantly associated with high mortality. When these significant variables were further analysed using logistic regression, age > 75 years and > 2 co-morbidities were only factors associated independently with high mortality. CONCLUSION In patients with age 50 years and above, following hip fracture surgery, age > 75 years and > 2 co-morbidities are the predictors of 1-year mortality when adjusted for other variable. A better designed multi-centric study can be more helpful in understanding the things in Indian context.

Bisphosphonates to reduce bone fractures in stage 3B+ chronic kidney disease: a propensity score-matched cohort study. Health Technol Assess 2021; 25:1-106.

Abstract
BACKGROUND Bisphosphonates are contraindicated in patients with stage 4+ chronic kidney disease. However, they are widely used to prevent fragility fractures in stage 3 chronic kidney disease, despite a lack of good-quality data on their effects. OBJECTIVES The aims of each work package were as follows. Work package 1: to study the relationship between bisphosphonate use and chronic kidney disease progression. Work package 2: to study the association between using bisphosphonates and fracture risk. Work package 3: to determine the risks of hypocalcaemia, hypophosphataemia, acute kidney injury and upper gastrointestinal events associated with using bisphosphonates. Work package 4: to investigate the association between using bisphosphonates and changes in bone mineral density over time. DESIGN This was a new-user cohort study design with propensity score matching. SETTING AND DATA SOURCES Data were obtained from UK NHS primary care (Clinical Practice Research Datalink GOLD database) and linked hospital inpatient records (Hospital Episode Statistics) for work packages 1-3 and from the Danish Odense University Hospital Databases for work package 4. PARTICIPANTS Patients registered in the data sources who had at least one measurement of estimated glomerular filtration rate of < 45 ml/minute/1.73 m2 were eligible. A second estimated glomerular filtration rate value of < 45 ml/minute/1.73 m2 within 1 year after the first was requested for work packages 1 and 3. Patients with no Hospital Episode Statistics linkage were excluded from work packages 1-3. Patients with < 1 year of run-in data before index estimated glomerular filtration rate and previous users of anti-osteoporosis medications were excluded from work packages 1-4. INTERVENTIONS/EXPOSURE Bisphosphonate use, identified from primary care prescriptions (for work packages 1-3) or pharmacy dispensations (for work package 4), was the main exposure. MAIN OUTCOME MEASURES Work package 1: chronic kidney disease progression, defined as stage worsening or starting renal replacement. Work package 2: hip fracture. Work package 3: acute kidney injury, hypocalcaemia and hypophosphataemia identified from Hospital Episode Statistics, and gastrointestinal events identified from Clinical Practice Research Datalink or Hospital Episode Statistics. Work package 4: annualised femoral neck bone mineral density percentage change. RESULTS Bisphosphonate use was associated with an excess risk of chronic kidney disease progression (subdistribution hazard ratio 1.12, 95% confidence interval 1.02 to 1.24) in work package 1, but did not increase the probability of other safety outcomes in work package 3. The results from work package 2 suggested that bisphosphonate use increased fracture risk (hazard ratio 1.25, 95% confidence interval 1.13 to 1.39) for hip fractures, but sensitivity analyses suggested that this was related to unresolved confounding. Conversely, work package 4 suggested that bisphosphonates improved bone mineral density, with an average 2.65% (95% confidence interval 1.32% to 3.99%) greater gain in femoral neck bone mineral density per year in bisphosphonate users than in matched non-users. LIMITATIONS Confounding by indication was a concern for the clinical effectiveness (i.e. work package 2) data. Bias analyses suggested that these findings were due to inappropriate adjustment for pre-treatment risk. work packages 3 and 4 were based on small numbers of events and participants, respectively. CONCLUSIONS Bisphosphonates were associated with a 12% excess risk of chronic kidney disease progression in participants with stage 3B+ chronic kidney disease. No other safety concerns were identified. Bisphosphonate therapy increased bone mineral density, but the research team failed to demonstrate antifracture effectiveness. FUTURE WORK Randomised controlled trial data are needed to demonstrate antifracture efficacy in patients with stage 3B+ chronic kidney disease. More safety analyses are needed to characterise the renal toxicity of bisphosphonates in stage 3A chronic kidney disease, possibly using observational data.

Tranexamic acid safely reduces hidden blood loss in patients undergoing intertrochanteric fracture surgery: a randomized controlled trial. Eur J Trauma Emerg Surg 2020; 48:731-741. [PMID: 32415365 DOI: 10.1007/s00068-020-01387-0] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/11/2020] [Accepted: 05/02/2020] [Indexed: 12/17/2022]
Abstract
PURPOSE To investigate the efficacy and safety of intravenous tranexamic acid (IV-TXA) in patients undergoing intertrochanteric fracture surgery. METHODS A total of 122 patients were included in this double-blinded trial and equally randomized to receive 1 g of IV-TXA or normal saline 10 min before incision and 3 h later. The primary efficacy outcome was calculated hidden blood loss (HBL). The secondary efficacy outcome was allogeneic erythrocyte transfusion rate during hospitalization. Safety outcome was a composite of thromboembolic events including deep venous thrombosis (DVT) up to 90 days. A meta-analysis combining this study with previous randomized controlled trials in hip fracture surgery (total sample size: 1112 patients) was also conducted. RESULTS The mean HBL in TXA group (640.96 ± 421.63 ml) was significantly lower than that in placebo group (1010.11 ± 398.96 ml, P < 0.001). The rate of erythrocyte transfusions was 29.5% in TXA group and 60.7% in placebo group (P = 0.001). The incidence of thromboembolic events at 90 days was 4.9% in TXA group and 1.6% in placebo group (P = 0.619). The updated meta-analysis showed that IV-TXA significantly reduced erythrocyte transfusion in hip fracture surgery (risk ratio 0.60, 95% confidence intervals 0.53-0.68), and IV-TXA caused no increased risk of thromboembolic events (risk difference 0.01, 95% confidence intervals - 0.02-0.04). CONCLUSION IV-TXA could effectively reduce the HBL and allogeneic erythrocyte transfusion requirements in patients undergoing intertrochanteric fracture surgery without an increase of thromboembolic events including DVT.

Alendronate use and bone mineral density gains in women with moderate-severe (stages 3B-5) chronic kidney disease: an open cohort multivariable and propensity score analysis from Funen, Denmark. Arch Osteoporos 2020; 15:81. [PMID: 32483674 PMCID: PMC8448716 DOI: 10.1007/s11657-020-00746-z] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/21/2019] [Accepted: 04/30/2020] [Indexed: 02/03/2023]
Abstract
UNLABELLED Bisphosphonates are contraindicated in moderate-to-severe chronic kidney disease patients. However, they are used to prevent fragility fractures in patients with impaired kidney function, despite a lack of evidence on their effects on bone density in these patients. We demonstrated that Alendronate had a positive effect on bone in these patients. PURPOSE This study aimed to assess the association between alendronate use and bone mineral density (BMD) change in subjects with moderate-severe chronic kidney disease (CKD). METHODS We created a cohort of CKD stage 3B-5 patients by linking all DXA-based measurements in the Funen area, Denmark, to biochemistry, national health registries and filled prescriptions. Exposure was dispensation of alendronate and the outcome was annualized percentage change in BMD at the femoral neck, total hip and lumbar spine. Individuals were followed from first BMD to the latest of subsequent DXA measurements. Alendronate non-users were identified using incidence density sampling and matched groups were created using propensity scores. Linear regression was used to estimate average differences in the annualized BMD. RESULTS Use of alendronate was rare in this group of patients: propensity score matching (PSM) resulted in 71 alendronate users and 142 non-users with stage 3B-5 CKD (as in the 1 year before DXA). Whilst alendronate users gained an average 1.07% femoral neck BMD per year, non-users lost an average of 1.59% per annum. The PSM mean differences in annualized BMD were + 2.65% (1.32%, 3.99%), + 3.01% (1.74%, 4.28%) and + 2.12% (0.98%, 3.25%) at the femoral neck, total hip and spine BMD, respectively, all in favour of alendronate users. CONCLUSION In a real-world cohort of women with stage 3B-5 CKD, use of alendronate appears associated with a significant improvement of 2-3% per year in the femoral neck, total hip and spine BMD. More data are needed on the anti-fracture effectiveness and safety of bisphosphonate therapy in moderate-severe CKD.

Abstract
PURPOSE The aim of this study is to assess the possible association between thyroid-stimulating hormone (TSH) and mortality in hip fracture patients. PATIENTS AND METHODS The study is based on a hip fracture database from Bispebjerg University Hospital (Copenhagen, Denmark). This database includes all hip fracture patients (ICD-10 codes DS720 (femoral neck), DS721 (pertrochanteric), and DS722 (subtrochanteric)) admitted to Bispebjerg Hospital from 1996 to 2012. From this database, we identified all surgically treated hip fracture patients aged > 60 years with available plasma TSH-measurements at admission. RESULTS Of the 914 included patients (24% men and 76% women), 10.5% died within 30 days. At inclusion, 161 (17.6%) of the patients were hyperthyroid (TSH < 0.65 mIU/L), 58 (6.4%) were hypothyroid (TSH > 4.8 mIU/L), while 695 (76.0%) were euthyroid (0.65 < TSH < 4.80 mIU/L), p = 0.03. Mortality was significantly higher in the two higher quartiles of TSH [Q3 (13.0%) and Q4 (15.4%)] compared to the two lower quartiles [Q1 (7.4%) and Q2 (6.2%), p = 0.0003. After adjustment for age, sex and Charlson Comorbidity Index (CCI) in a Cox proportional hazard model, the risk of 30-day mortality continued to be increased in patients with TSH above the median as compared to patients with TSH below the median (HR 2.1 (1.4-3.3), p = 0.0006]. CONCLUSION The study demonstrates increased 30-day mortality in surgically treated hip fracture patients with plasma TSH levels above the median (1.41 mIU/L) at admission, even after adjusting for age, sex and CCI.

Abstract
AIMS Low haemoglobin (Hb) at admission has been identified as a risk factor for mortality for elderly patients with hip fractures in some studies. However, this remains controversial. This study aims to analyze the association between Hb level at admission and mortality in elderly patients with hip fracture undergoing surgery. PATIENTS AND METHODS All consecutive patients (prospective database) admitted with hip fracture operated in a tertiary hospital between 2012 and 2016 were analyzed. We collected patient characteristics, time to surgery, duration and type of surgery, comorbidities, Hb at admission, nadir of Hb after surgery, the use and amount of red blood cells (RBCs) transfusion products, postoperative complications, and death. The main outcome measures were mortality at 30 days, 90 days, 180 days, and one year after surgery. RESULTS We included 829 patients; the mean age was 81 years (sd 11). Mortality at 30 days, 90 days, 180 days, and one year was 5.7%, 12.3%, 18.1%, and 23.5%, respectively. The highest mortality was observed in patients aged over 80 years (162/557, 29%) and in male patients (85/267, 32%). Survival at 90 days, 180 days, and one year after surgery was significantly lower in patients with a Hb level below 120 g/l at admission. In multivariate analysis, Hb level below 120 g/l at admission was found to be an independent factor associated with mortality (adjusted hazard ratio (aHR) 1.68 (95% confidence interval (CI) 1.22 to 2.31); p = 0.001), along with age (aHR 1.06 (95% CI 1.04 to 1.06); p < 0.001), male sex (aHR 2.19 (95% CI 1.61 to 2.96); p < 0.001), and need for RBC transfusions (aHR 1.10 (95% CI 1.02 to 1.19); p = 0.01). CONCLUSION Our results suggest that low Hb at admission along with age and RBC transfusions is significantly associated with short- and long-term mortality after hip fracture surgery, independently of comorbidity confounders. Further studies should be performed to understand how preoperative Hb could be taken into account in perioperative management. Cite this article: Bone Joint J 2019;101-B:1122-1128.

Abstract
UNLABELLED Hip fractures are associated with increased mortality and it is important to identify risk factors. This study demonstrates that preexisting cardiovascular disease as well as cardiovascular biomarkers that are associated with increased 30-day mortality. These findings can be used to identify high-risk patients who might benefit from specialized care. INTRODUCTION This study investigates the association between cardiovascular disease (CVD), cardiovascular biomarkers, and 30-day mortality following a hip fracture. METHODS The Danish National Patient Registry was used to investigate the association between CVD and mortality following hip fracture in a nationwide population-based cohort study. In a subset of the included patients (n = 355), blood samples were available from a local biobank. These samples were used for analyzing the association between specific biochemical markers and mortality. The primary outcome was 30-day mortality. RESULTS A total of 113,211 patients were included in the population-based cohort study. Among these, heart failure was present in 9.4%, ischemic heart disease in 15.9%, and ischemic stroke in 12.0%. Within 30 days after the hip fracture, 11,488 patients died, resulting in an overall 30-day mortality of 10.1%. The 30-day mortality was significantly increased in individuals with preexisting CVD with multivariably adjusted odds ratios of 1.69 (95% confidence interval, 1.60-1.78) for heart failure, 1.23 (1.17-1.29) for ischemic heart disease, and 1.06 (1.00-1.12) for ischemic stroke. In the local database including 355 patients, 41 (11.5%) died within 30 days. The multivariably adjusted odds ratio for 30-day mortality increased with increasing NT-proBNP (2.36 [1.53-3.64] per quartile) and decreased with increasing HDL cholesterol (0.58 [0.41-0.82] per quartile). On this basis, we established a model for predicting the probability of death based on the biochemical markers. CONCLUSION Preexisting CVD was associated with increased 30-day mortality after a hip fracture. Furthermore, high levels of NT-proBNP and low levels of HDL cholesterol were associated with increased 30-day mortality.

Abstract
Approximately 14-40% of patients in industrialized countries present with preoperative anemia. Depending on the severity, anemia is associates with increased perioperative morbidity and mortality. One of the most important causes of preoperative anemia is iron deficiency which is usually easy to treat. Implemented in the multimodal concept of patient blood management, the diagnostics and treatment of preoperative anemia are important aspects for improvement of perioperative outcome. Adequate and early diagnostics of the cause of anemia before treatment is important because treatment options, e.g. with iron, erythropoetin, folic acid and vitamin B12, may be expensive, may have severe side effects, and in the case of a wrong indication, will not improve anemia. In addition, an adequate regeneration of the erythrocyte volume requires time. This review article presents important aspects of the epidemiology and prognostic implications of preoperative anemia, the physiology and pathophysiology of anemia as well as diagnostic features and the evidence base for preoperative treatment options.

Abstract
ABSTRACT Objective: to estimate the incidence of red blood cell concentrate orders in elective femur fracture repair surgeries and to identify predictors for hemotranfusion. Method: retrospective cohort study conducted with 271 patients submitted to femur fracture repair surgery between July 2013 and July 2016. Surgical and transfusion data were obtained from patient charts and the Transfusion Management System. Association between sociodemographic and clinical variables related to the surgical procedure and the occurrence of red blood cell concentrate transfusion was analyzed using descriptive statistics, the chi-squared test, relative risk, and odds ratio. Multivariate analysis was performed using binomial logistic regression. Results: the incidence of blood orders for patients undergoing femur fracture repair surgery was 87%. Ninety-one (33.6%) patients received red blood cell concentrate transfusions. Even though placing blood orders is recommended, given the possibility of intra- or postoperative transfusions, only 52 (47.2%) blood transfusions occurred in the preoperative period. The variables female sex, low preoperative hemoglobin levels and procedure lasting longer than 120 minutes presented statistical significance (p<0.05) and were considered predictors for hemototransfusion. Conclusion: Perioperative nursing must be aware of the importance of blood orders for all patients undergoing femur fracture repair surgery, including in the preoperative period, with special attention to patients who are female, previously anemic and submitted to long-lasting procedures.

Abstract
PURPOSE The study aims to analyze the incidence of 30-day mortality in elderly patients who underwent surgery for hip fractures and its associated factors. METHODS A prospective multicentric study was performed. All patients aged ≥ 65 years, with fragility hip fractures, consecutively admitted in two Italian hospitals were included. Patients with periprosthetic or pathological fractures were excluded. Logistic regression was used to identify patient and patient care variables that independently influenced the 30-day mortality and receiver operating characteristic (ROC) curve analysis to assess their predictive capacity on the outcome. RESULTS Of the patients, 728 met the inclusion criteria, of whom approximately 5% died within 30 days after admission. The 45.7% of the deceased patients died while hospitalized. Multivariate analysis showed that advancing age was the only independent predictor of 30-day mortality (OR = 1.084, 95% CI = 1.024-1.147), while a higher presence of informal caregivers was a protective factor (OR = 0.988, 95% CI = 0.979-0.997). The area under the ROC curve of the model was 0.723 (CI95% 0.676-0.770) for 30-day mortality in elderly hip fractures patients. CONCLUSIONS Patients with an advanced age need careful follow-up, especially within 30 days following operation for hip fracture; at the same time, the presence of informal caregivers at the patient's bedside should be promoted.

Abstract
Background: Enhanced recovery pathways (ERPs) have been shown to improve patient outcomes in a variety of contexts. This review summarizes the evidence and defines a protocol for perioperative care of patients with hip fracture and was conducted for the Agency for Healthcare Research and Quality safety program for improving surgical care and recovery. Study Design: Perioperative care was divided into components or “bins.” For each bin, a semisystematic review of the literature was conducted using MEDLINE with priority given to systematic reviews, meta-analyses, and randomized controlled trials. Observational studies were included when higher levels of evidence were not available. Existing guidelines for perioperative care were also incorporated. For convenience, the components of care that are under the auspices of anesthesia providers will be reported separately. Recommendations for an evidence-based protocol were synthesized based on review of this evidence. Results: Eleven bins were identified. Preoperative risk factor bins included nutrition, diabetes mellitus, tobacco use, and anemia. Perioperative management bins included thromboprophylaxis, timing of surgery, fluid management, drain placement, early mobilization, early alimentation, and discharge criteria/planning. Conclusions: This review provides the evidence basis for an ERP for perioperative care of patients with hip fracture.

Abstract
Background factors affecting mortality after hip fracture surgery have been studied extensively. It has been suggested that do-not-resuscitate (DNR) orders are associated with higher mortality in surgical patients due to less aggressive treatment. However, the effect of DNR orders on mortality in hip fracture patients is unknown. The objective of this study was to investigate the effect of DNR orders on early mortality after hip fracture surgery. Methods all patients undergoing hip fracture surgery between 2004 and 2015 were included in this retrospective study. Patient characteristics such as age, comorbidities and fracture type were collected, as were resuscitation preferences. Multivariable logistic regression analysis was performed to identify independent risk factors for early mortality. Results a total of 1,803 patients were analysed, of which 823 (45.6%) had DNR orders. DNR patients were older, more often female, had lower haemoglobin levels and more comorbidities when compared with non-DNR patients. The unadjusted effect of DNR orders on mortality was high (OR: 2.39; P < 0.001). Multivariable analysis demonstrated that increased age, male gender, higher American Society of Anesthesiologists score, low admission haemoglobin, living in an institution, high Charlson Comorbidity Index and delay to surgery were associated with increased early mortality after hip fracture surgery. There was no independent effect of DNR orders on mortality after adjustment for these variables (P = 0.735). Conclusions DNR patients have higher mortality rates due to poor health status. Resuscitation preferences on their own are not associated with early mortality after hip fracture surgery.
