Is hip fracture surgery safe for patients on antiplatelet drugs and is it necessary to delay surgery? A systematic review and meta-analysis

Related factors of postoperative half-year care utilization for health status and recovery in older adults with hip fracture: A retrospective study of Osaka National Health Insurance Data

AIM

The aim of this study was to investigate the relationship between preoperative patient factors and postoperative half-year health care utilization reflecting recovery, common complications, comorbidities, and significant health concerns, identifying strong risk and protective factors.

METHODS

This retrospective cohort study utilized linear, quantile, and ordinal regressions to analyze Osaka National Health Insurance data from 26 606 elderly patients who underwent hip fracture surgery between 2012 and 2018.

RESULTS

The key factors associated with multiple postoperative care utilizations (P < 0.001) included: 1 Compared with men, women were strongly negatively correlated with postoperative length of stay (LOS) at q90, diabetes prescriptions or drip injections, while showing strong positive associations with postoperative antihypertensive, antiosteoporosis, and antidementia prescriptions. 2 Age has a strong negative correlation with antiosteoporosis or diabetes prescriptions but strongly positive associations with indwelling urinary catheters or drip injections. 3 The preoperative 1-year LOS correlated positively with the postoperative LOS or indwelling urinary catheters, and the strongest associations were observed at q25 with the postoperative LOS. It was significantly and negatively associated with antihypertensive or antidementia prescriptions. 4 Many preoperative care utilizations were positive factors, and some were strong factors at q25 of the LOS.

CONCLUSIONS

Nuanced relationships between the female sex; preoperative LOS; antidementia, antiosteoporosis, antihypertensive and constipation prescriptions; indwelling catheters, and postoperative LOS were elucidated. These are key risks during shorter postoperative LOS, while male subgroups are at a higher risk during longer LOS duration. Patients with extended preoperative diabetes prescriptions or drip injections are at high risk of multiple postoperative care. Geriatr Gerontol Int 2025; 25: 190-205.

Simultaneous transcatheter aortic valve implantation and femoral osteosynthesis: a case report

BACKGROUND

Simultaneous cardiac and non-cardiac surgeries can be beneficial for patients, but there are still few reports on this approach.

CASE PRESENTATION

A 90-year-old woman was diagnosed with a femoral trochanteric fracture and severe aortic stenosis. A heart team conference decided to perform transcatheter aortic valve implantation (TAVI) and femoral osteosynthesis under general anesthesia on the same day. A preoperative simulation was conducted to review the surgical procedure and confirm the arrangement of the operating table and instruments. Preoperative management was carried out with attention to the risk of myocardial ischemia caused by bleeding or pain from the fracture. Transfemoral TAVI was completed without trouble, and after the patient was moved to the traction table, osteosynthesis was started. Back-up pacing with a temporary pacemaker was activated for atrioventricular block and bradycardia. After completing the surgery, the patient recovered from anesthesia, and extubation was performed after confirming the absence of paralysis. The patient had no noticeable postoperative complications and successfully underwent rehabilitation.

CONCLUSIONS

Through meticulous preparation and perioperative management, we were able to perform TAVI and femoral osteosynthesis simultaneously, achieving a favorable outcome.

Cardiovascular diseases, prevention, and management of complications in older adults and frail patients treated for elective or post-traumatic hip orthopaedic interventions: a clinical consensus statement of the ESC Council for Cardiology Practice (CCP), the European Association of Preventive Cardiology (EAPC), the Association for Acute CardioVascular Care (ACVC), the Association of Cardiovascular Nursing & Allied Professions of the ESC (ACNAP), the ESC Working Group on Aorta and Peripheral Vascular Diseases (WG APVD), and the ESC Working Group on Thrombosis (WG T)

Due to the aging population, focusing on healthy aging has become a global priority. Cardiovascular diseases (CVDs) and frailty, characterized by increased vulnerability to adverse stress and health events, interact synergistically in advanced age. In older adults, hip fractures are a frequent dramatic "life-transition" event. Conditions such as arrhythmias, orthostatic hypotension, heart failure, peripheral artery disease and adverse drug reactions may facilitate falls and thus bone fractures in older adults. Cardiovascular complications or the worsening of previous CVDs may increase the degree of frailty and disability following this surgery. The close relationship between older age, CVDs, frailty and orthopaedic surgery leads to the need to focus on the various phases of interventions in a multidisciplinary approach. This document aims to provide practical support to prevent cardiovascular complications in older and frail patients undergoing hip procedures by suggesting specific assessments and interventions. In particular, in pre-operative care the focus should be on the assessment and management of concomitant CVD and frailty, while immediate peri- and post-operative care should highlight specific concerns for anesthesia, prevention and management of thrombotic complications, specific nursing needs, including the prevention of infections and delirium, and the establishment of an integrated rehabilitation program focusing on CVDs and the risk of new falls, with a positive role for care-givers. Furthermore, by optimizing the "hip surgery pathway" the objective is to help avoid the deterioration of health and loss of independence that often result from this surgery through the correct management of cardiovascular patients in this peculiar context.

The management of anticoagulated fragility femoral fracture patients

Approximately 20% of patients sustaining a fragility femur fracture use an anticoagulant, and over 30% use an antiplatelet medication, both of which can result in surgical delay. Previously confined to fractures of the proximal femur, performance assessment, outcome and surgical delay is now assessed for all fractures of the femur in older patients, including those involving implants. This narrative review draws together all literature pertaining to anticoagulation and antiplatelet management in older patients with a fracture of the femur to address 5 key points: prevalence of anticoagulant and antiplatelet use; analysis of management protocols; collation of national guidelines; comparison of perioperative management; timing of surgery and perioperative outcomes.Our review found that the prevalence of fragility femur fracture patients taking anticoagulant and antiplatelet medication ranges from 20-40% and 25-35% respectively. More anticoagulated patients are taking direct oral anticoagulants compared to vitamin k antagonists with growing implications for variation in practice and delays to surgery.Several national guidelines exist although these are characterised by marked variation, there is little standardisation, and none are generalised across all fragility femur fractures.Expedited surgery within 36 hours of admission in patients taking an anticoagulant or antiplatelet medication is safe and has been demonstrated in fractures of the proximal femur across many small number studies although no such evidence exists in non-proximal femur fractures despite this population sharing similar characteristics. There is a need for all fractures of the femur in older people to be considered when researching and assessing performance in this population to prevent needless variation and delay.

Perioperative Management of Traditional and Direct Oral Anticoagulants in Hip Fracture Patients

Hip fractures are an increasingly common injury in the senior population and almost always require surgical fixation or prosthetic replacement. These surgeries, according to the American Academy of Orthopaedic Surgeons, are considered high-risk for bleeding, especially in a population fraught with comorbidities and often presenting on anticoagulation medications. Direct oral anticoagulants represent a class of drugs that have been becoming more popular in use in this population, with many benefits over the historically used Warfarin. There are recommendations for preoperative discontinuation and postoperative resumption of these medications, which can be more readily managed for elective surgeries. However, there is a paucity of literature detailing best practice guidelines for the perioperative management of direct oral anticoagulants when a patient presents with a hip fracture. This review article summary of the periprocedural management of DOACs for hip surgery was developed by examining the American College of Chest Physicians evidence-based clinical practice guidelines, Perioperative Guidelines on Antiplatelet and Anticoagulant Agents written by anesthesiologists, various retrospective studies, and drug labels for pharmacokinetic data. These recommendations should be used as a guideline, along with the collaboration of multidisciplinary hospital teams during inpatient admission, to manage these complex patients.

Safety of Early Surgery in Hip Fracture Patients Taking Clopidogrel and/or Aspirin: A Systematic Review and Meta-Analysis

BACKGROUND

The aim of this study was to investigate the safety of early surgery in hip fracture patients who took clopidogrel and/or aspirin.

METHODS

A systematic search was conducted using databases, including PubMed/MEDLINE, Embase, Cochrane Library, and Web of Science, for studies relating to early arthroplasty or internal fixation for femoral neck fractures, intertrochanteric fractures, and subtrochanteric fractures in patients taking clopidogrel and/or aspirin. A total of 20 observational studies involving 3,077 patients were included in this meta-analysis, and analyzed in groups of early surgery versus delayed surgery, and clopidogrel and/or aspirin versus nonantiplatelet agents.

RESULTS

Patients in the clopidogrel and/or aspirin group who underwent early surgery had significantly more intraoperative blood loss than those in the non-antiplatelet group (mean difference = 17.96, 95% confidence interval [CI] [4.37, 31.55], P = .01), and patients in the clopidogrel and/or aspirin group had a lower overall incidence of complications after early surgery than those in the delayed surgery group (odds ratio = 0.26, 95% CI [0.14, 0.29], P < .001) and a shorter length of hospital stay (odds ratio = 0.26, 95% CI [0.14, 0.29], P < .001). There was no significant difference in postoperative mortality and other related indicators.

CONCLUSIONS

Early surgery in hip fracture patients taking clopidogrel and/or aspirin appears to be safe based on the available evidence and needs to be clarified by higher quality studies. However, the increased risk of cardiovascular events associated with discontinuation of clopidogrel or clopidogrel combined with aspirin dual antiplatelet therapy requires attention in the perioperative period.

Safety of urgent surgery for the patients with proximal femur fracture treated with platelet aggregation inhibitors: a propensity-score matching analysis

INTRODUCTION

To compare the various perioperative outcomes in an urgent surgery setting among patients with proximal femur fracture (PFF) who received platelet aggregation inhibitors (PAIs) and those who did not.

METHODS

We retrospectively reviewed the data of 1,838 patients who underwent surgery for PFF between January 2011 and January 2021. We conducted 1:1 propensity-score matching and compared the perioperative outcomes, including operation time, postoperative complications, hospital stay, mortality, and variables related to bleeding risk (e.g., number of transfusion profiles, hemoglobin levels, and laboratory data, including coagulation battery).

RESULTS

Of the 492 patients who were treated with PAIs, 484 were 1:1 matched to the untreated control group. The PAI group showed shorter operation time than the matched control group (72.3 min for PAI vs. 77.7 min for control; P = 0.041), and the control group showed more pulmonary thromboembolism (0.2% for PAI vs 1.7% for control; P = 0.046) than the PAI group. The other complications and length of hospital stay, mortality rate, transfusion profile, and the laboratory test (except preoperative international normalized ratio, INR) showed no significant difference between the groups. Subgroup analyses of the patients treated with only aspirin (aspirin: 306, matched control: 306), only clopidogrel (clopidogrel: 100, matched control: 100), and others who were treated with dual anticoagulation (dual anticoagulation: 78, matched control: 78) showed no significant differences in perioperative outcomes among the groups.

CONCLUSION

The patients who were treated with PAI could undergo PFF surgery safely without delay, which led to no significant difference in operation time, postoperative complication risk, perioperative blood transfusion, and variables related to bleeding risk. Therefore, we believe that it is unnecessary to delay surgery for patients with PFF who receive PAI.

[Current Management of Patients with Proximal Femur Fractures Receiving Antiplatelet and Anticoagulant Therapy]

Proximal femur fractures (PFF) pose a major challenge in elderly patients with severe comorbidities and receiving antithrombotic therapy since according to the latest guidelines the surgery should be performed as soon as possible, preferably within 24 hours, to reduce mortality and morbidity. This review outlines the practical approach to surgical management of PFF that relies on increasing evidence of safety of early surgery in patients with PFF receiving antiplatelet and anticoagulant therapy. We have also used information from the existing evidence-based guidelines for elective/planned surgery in patients with antithrombotic therapy. The practical approach can be summarised as follows: • Antiplatelet therapy - discontinuation of acetylsalicylic acid (ASA) and clopidogrel in monotherapy or in combination is not necessary prior to surgery. In case of bleeding, antifibrinolytic therapy is recommended as well as administration of platelet concentrate which is rarely needed. • In patients taking warfarin, reversal of its effects is recommended by early administration of vitamin K to allow surgery to be performed within 24 hours. Prothrombin complex concentrate (PCC) as a second-line drug is reserved for extreme cases only. Warfarin therapy is resumed 24 hours after surgery. • Direct oral anticoagulants must be discontinued 24-48 hours prior to surgery, possibly longer depending on the type of drug, time of administration of the last dose, and renal function. In extreme cases, an antidote (idarucizumab, off-label andexanet) can be administered prior to surgery, or PCC in case they are unavailable. Anticoagulation therapy is resumed in 24-48 hours. • Neuraxial anaesthesia is possible when ASA is taken by the patient and in case of effective warfarin reversal. • In early surgery and rapid restart of anticoagulant therapy, bridging therapy with LMWH is not indicated except for in cases with extreme risk of thrombosis. Key words: proximal femur fracture, antiplatelet therapy, anticoagulant therapy, perioperative management.

Return to work after traumatic spinal fractures and spinal cord injuries: a retrospective cohort study

This study aimed to determine the factors associated with return to work (RTW) after traumatic spinal fracture and spinal cord injury. It provided a predictive model for RTW among patients with spinal fractures and spinal cord injury and determined important factors influencing the time to RTW after injury. A retrospective cohort study was conducted in Poursina Tertiary Hospital, Guilan, Iran between May 2017 and May 2020. Patients aged 18 to 65 who were hospitalized with traumatic spinal fractures and spinal cord injuries were included. Demographic and clinical data were collected from the National Spinal Column/Cord Injury Registry of Iran (NSCIR-IR). A researcher-administered questionnaire was used through a telephone interview to obtain complementary data on social and occupational variables. Kaplan-Meier survival analysis was used to estimate the average time to RTW and the predictors of RTW were determined by multivariate Cox regression model. Of the 300 patients included, 78.6% returned to work and the average time to RTW was about 7 months. The mean age of the participants was 45.63 ± 14.76 years old. Among the study variables, having a Bachelor's degree (HR 2.59; 95% CI 1.16-5.77; P = 0.019), complications after injury (HR 0.47; 95% CI 0.35-0.62; P = 0.0001), full coverage health insurance (HR 1.73; 95% CI 1.10-2.72; P = 0.016), opium use (HR 0.48; 95% CI 0.26-0.90; P = 0.023), number of vertebral fractures (HR 0.82; 95% CI 0.67-0.99; P = 0.046), and length of hospital stay (HR 0.95; 95% CI 0.93-0.98; P = 0.001) were found to be significant in predicting RTW in Cox regression analysis. Our analysis showed that wealthier people and those with high job mobility returned to work later.

Anticoagulation management in elderly patients with proximal femur fractures - overview of current concepts

Objectives

Proximal femur fractures (PFF) are common injuries in elderly patients and can have considerable effects on their quality of life, morbidity, and mortality. Due to pre-existing comorbidities, the prevalence of anticoagulated patients is increasing. The right timing for surgery and perioperative anticoagulation treatment remains controversial.

Content

This overview aims to summarize current practices in the pre- and postoperative anticoagulation management and the recommended time to surgery in elderly patients with PFF.

Summary and Outlook

Time to surgery for anticoagulated patients is often prolonged due to worries about serious perioperative bleeding and higher transfusion demands. But the delay of surgical PFF treatment increases the risk for perioperative complications like pulmonary embolism, pneumonia, deep vein thrombosis and urinary tract infections. Early surgery can be achieved with a consistent and interdisciplinary perioperative anticoagulation management. Antiplatelets do not have to be discontinued and surgery should be performed early without delay. For patients taking vitamin K antagonists (VKA) an INR less than 1.5 is recommended prior to surgery, which can be achieved by pausing VKA intake or by administering vitamin K, prothrombin complex concentrate (PCC) or fresh frozen plasma (FFP). For the treatment with direct oral anticoagulants (DOAC) a plasma drug level of under 50 pg/mL is considered safe for surgery. If the plasma level can not be determined, a gap of 24 h between the last DOAC dose and surgery is recommended. The systemic administration of tranexamic acid can reduce overall blood loss and transfusion rates in anticoagulated patients with PFF. Surgical treatment of PFF should be performed within 24 h, as delayed surgery increases the risk for perioperative complications. This also applies to anticoagulated patients, when clinically appropriate. International and interdisciplinary guidelines are necessary to ensure early and appropriate treatment of anticoagulated elderly patients with PFF.

The European guideline on management of major bleeding and coagulopathy following trauma: sixth edition

BACKGROUND

Severe trauma represents a major global public health burden and the management of post-traumatic bleeding continues to challenge healthcare systems around the world. Post-traumatic bleeding and associated traumatic coagulopathy remain leading causes of potentially preventable multiorgan failure and death if not diagnosed and managed in an appropriate and timely manner. This sixth edition of the European guideline on the management of major bleeding and coagulopathy following traumatic injury aims to advise clinicians who care for the bleeding trauma patient during the initial diagnostic and therapeutic phases of patient management.

METHODS

The pan-European, multidisciplinary Task Force for Advanced Bleeding Care in Trauma included representatives from six European professional societies and convened to assess and update the previous version of this guideline using a structured, evidence-based consensus approach. Structured literature searches covered the period since the last edition of the guideline, but considered evidence cited previously. The format of this edition has been adjusted to reflect the trend towards concise guideline documents that cite only the highest-quality studies and most relevant literature rather than attempting to provide a comprehensive literature review to accompany each recommendation.

RESULTS

This guideline comprises 39 clinical practice recommendations that follow an approximate temporal path for management of the bleeding trauma patient, with recommendations grouped behind key decision points. While approximately one-third of patients who have experienced severe trauma arrive in hospital in a coagulopathic state, a systematic diagnostic and therapeutic approach has been shown to reduce the number of preventable deaths attributable to traumatic injury.

CONCLUSION

A multidisciplinary approach and adherence to evidence-based guidelines are pillars of best practice in the management of severely injured trauma patients. Further improvement in outcomes will be achieved by optimising and standardising trauma care in line with the available evidence across Europe and beyond.

Quality of Life and Post-Surgical Complications in Patients on Chronic Antiplatelet Therapy with Proximal Femur Fracture: 12-Month Follow-Up after Implementing a Strategy to Shorten the Time to Surgery

BACKGROUND

We evaluated a strategy to shorten the time from admission to surgery in patients with proximal femur fractures on chronic antiplatelet therapy. We reported a 12-month follow-up on complications and quality of life (QoL).

METHODS

Multicentre, open-label, randomized, parallel clinical trial. Patients were randomized to either early platelet function-guided surgery (experimental group) or delayed surgery (control group). Medical and surgical complications and QoL (EQ-5D-5L questionnaire) were assessed during the hospital stay, and after hospital discharge at 30 days, and 6 and 12 months.

RESULTS

From 156 randomized patients, 143 patients underwent surgery. The mean age was 85.5 (7.8) years and 68.0% were female. After hospital discharge, 5.7% of patients had surgical wound complications and 55.9% had medical complications, with 42.7% having serious adverse events. QoL improved significantly after surgery, with the best scores at the six-month follow-up. The overall mortality was 32.2%. There were no differences between early and delayed surgery groups in any assessed outcomes.

CONCLUSION

It seems safe to reduce the time of surgery under neuraxial anaesthesia in patients with hip fractures on chronic antiplatelet therapy by platelet function testing. QoL in particular improves in the first six months after surgery.

Retrospective cohort study to determine the effect of preinjury antiplatelet or anticoagulant therapy on mortality in patients with major trauma

Objective

This study aimed to compare outcomes among patients who sustained major trauma from injury with and without receiving antiplatelet therapy (APT) or anticoagulant therapy (ACT) to test the hypothesis that APT does not increase the risk of mortality. However, ACT increases the mortality risk in the acute phase of trauma.

Methods

Patients registered in the Japanese Observational body for Coagulation and Thrombolysis in Early Trauma 2 between April 2017 and March 2018 who had sustained a severe injury in any anatomic region of the body, as determined using an injury severity score (ISS) ≥ 16 were included in this retrospective cohort study. We analyzed the mortality within 24 h from the arrival using a multivariable linear regression analysis adjusted for several confounding variables.

Results

We identified 1,186 eligible participants who met the inclusion criteria for this study: 105 in the APT (cases), 1,081 in the non-antiplatelet therapy (nAPT) group (controls), 65 in the ACT (cases), and 1,121 in the non-anticoagulant therapy (nACT) group (controls). The mortality within 24 h in the ACT group was significantly higher than in the nACT group (odds ratio 4.5; 95%CI: 1.2-16.79; p = 0.025); however, there was no significant difference between the two groups with or without the antiplatelet drug (odds ratio 0.32; 95%CI: 0.04-2.79; p = 0.3) administration. Other outcomes, like the 28-day mortality, mortality at discharge, and surgery for hemostasis, were not significantly different between regular users and non-users of either antiplatelet or anticoagulant drugs.

Conclusion

Regular antiplatelet medications did not increase mortality within 24 h, 28 days, or at discharge in patients with major trauma, suggesting that standard treatment, including surgery, is sufficient.

Proximal Femoral Fractures in the Elderly: A Few Things to Know, and Some to Forget

Hip fractures are a leading cause of hospitalisation in elderly patients, representing an increasing socioeconomic problem arising from demographic changes, considering the increased number of elderly people in our countries. Adequate peri-operative treatment is essential to decrease mortality rates and avoid complications. Modern management should involve a coordinated multidisciplinary approach, early surgery, pain treatment, balanced fluid therapy, and prevention of delirium, to improve patients' functional and clinical outcomes. The operative treatment for intertrochanteric and subtrochanteric fractures is intramedullary nail or sliding/dynamic hip screw (DHS) on the basis of the morphology of the fracture. In the case of neck fractures, total hip replacement (THR) or hemiarthroplasty are recommended. However, several topics remain debated, such as the optimum thromboprophylaxis to reduce venous thromboembolism or the use of bone cement. Postoperatively, patients can benefit from early mobilisation and geriatric multidisciplinary care. However, during the COVID-19 pandemic, a prolonged time to operation with a subsequent increased complication rate have burdened frail and elderly patients with hip fractures. Future studies are needed with the aim to investigate better strategies to improve nutrition, postoperative mobility, to clarify the role of home-based rehabilitation, and to identify the ideal analgesic treatment and adequate tools in case of patients with cognitive impairment.

In reply to the letter to the editor regarding "Comparison of a twin interlocking derotation and compression screw cephalomedullary nail (InterTAN) with a single screw derotation cephalomedullary nail (proximal femoral nail antirotation): a systematic review and meta-analysis for intertrochanteric fractures"

Background

Intertrochanteric hip fractures are common and devastating injuries, especially for the elderly. Surgical treatment is the optimal strategy for managing intertrochanteric fractures as it allows early rehabilitation and functional recovery. The relative effects of internal fixation strategies for intertrochanteric fracture after operation remain limited to relatively small studies which create uncertainty in attempts to establish evidence-based best practice.

Methods

We conducted a systematic review and meta-analysis of randomised controlled trials (RCTs) and observational studies to assess the clinical effectiveness of two commonly used intramedullary devices: a twin-screw integrated cephalomedullary nail (InterTAN) versus a single-screw cephalomedullary nail (proximal femoral nail antirotation) in patients with intertrochanteric fractures. The following outcomes were considered: revisions, implant-related failures, non-unions, pain, Harris hip score and intra-operative outcomes. Odds ratios or mean differences with 95% confidence intervals in brackets are reported.

Results

Six studies met the inclusion criteria: two randomised controlled trials and four observational studies enrolling 970 patients with a mean age of 77 years and 64% of patients being female. There was a statistically significant difference (p value < 0.05) for revisions OR 0.27 (0.13–0.56), implant-related failures OR 0.16 (0.09–0.27) and proportion of patients complaining of pain OR 0.50 (0.34–0.74). There was no difference in non-unions and Harris hip score (p value > 0.05). There was a significant difference in blood loss and fluoroscopy usage in favour of PFNA, while no difference in operating times was observed between the two devices.

Conclusions

Our meta-analysis suggests that a twin-screw integrated cephalomedullary nail (InterTAN) is clinically more effective when compared to a single-screw cephalomedullary nail proximal femoral nail antirotation resulting in fewer complications, fewer revisions and fewer patients complaining of pain. No difference has been established regarding non-unions and Harris hip score. Intra-operative outcomes favour PFNA with less blood loss and fluoroscopy usage. Further studies are warranted to explore the cost-effectiveness of these and other implants in managing patients with intertrochanteric fractures.

Association between osteoporosis or osteopenia and taking antiplatelet agents in general US population of NHANES

BACKGROUND

Osteoporosis (OP) and osteopenia are common bone disorders in old age, and lots of patients suffering from OP or osteopenia need to take antiplatelet agents to treat basic diseases. However, clinical data on the link between osteopenia or OP and antiplatelet agents are limited.

METHODS

Data in this study were collected and screened from the NHANES from 2013 to 2014 and 2017 to 2018. The variables were extracted from interviews and compared between OP or osteopenia participants and normal. The relationship between OP or osteopenia and taking antiplatelet drugs was analyzed by weighted multivariate logistic regression.

RESULTS

After excluding individuals who were not eligible and had invalid data, we finally identified 894 participants for inclusion in the study. We found a negative association between OP or osteopenia and taking antiplatelet agents (OR = 0.53; 95% CI, 0.33-0.84; p < 0.05). These results did not change on multiple imputations (OR = 0.32, 95% CI, 0.19-0.56; p <0.01). In the subgroup analyses, the associations were more significant in women (OR = 0.18, 95% CI, 0.05-0.62; p <0.05).

CONCLUSION

This study demonstrated that the association between OP or osteopenia and taking antiplatelet agents was significant. Therefore, it is necessary to confirm the result by extending further research.

Early Surgery with Neuraxial Anaesthesia in Patients on Chronic Antiplatelet Therapy with a Proximal Femur Fracture: Multicentric Randomised Clinical Trial

Background: Patients with proximal femur fracture on antiplatelet treatment benefit from early surgery. Our goal was to perform early surgery under neuraxial anaesthesia when indicated by the platelet function test. Methods: We conducted a multicentre randomised open-label parallel clinical trial. Patients were randomised to either early platelet function-guided surgery (experimental group) or delayed surgery (control group). Early surgery was programmed when the functional platelet count (as measured by Plateletworks) was >80 × 10⁹/L. The primary outcome was the emergency admission-to-surgery interval. Secondary outcomes were platelet function, postoperative bleeding, medical and surgical complications, and mortality. Results: A total of 156 patients were randomised, with 78 in each group, with a mean (SD) age of 85.96 (7.9) years, and 67.8% being female. The median (IQR) time to surgery was 2.3 (1.5–3.7) days for the experimental group and 4.9 (4.4–5.6) days for the control group. One-third of patients did not achieve the threshold functional platelet count on the first day of admission, requiring more than one test. There was no difference in clinical outcomes between groups. Conclusions: A strategy individualised according to the platelet function test shortens the time to proximal femur fracture surgery under neuraxial anaesthesia in patients on chronic antiplatelet treatment. Better powered randomised clinical trials are needed to further evaluate the clinical impact and safety of this strategy.

Orthogeriatric co-management for the care of older subjects with hip fracture: recommendations from an Italian intersociety consensus

BACKGROUND

Health outcomes of older subjects with hip fracture (HF) may be negatively influenced by multiple comorbidities and frailty. An integrated multidisciplinary approach (i.e. the orthogeriatric model) is, therefore, highly recommended, but its implementation in clinical practice suffers from the lack of shared management protocols and poor awareness of the problem. The present consensus document has been implemented to address these issues.

AIM

To develop evidence-based recommendations for the orthogeriatric co-management of older subjects with HF.

METHODS

A 20-member Expert Task Force of geriatricians, orthopaedics, anaesthesiologists, physiatrists, physiotherapists and general practitioners was established to develop evidence-based recommendations for the pre-, peri-, intra- and postoperative care of older in-patients (≥ 65 years) with HF. A modified Delphi approach was used to achieve consensus, and the U.S. Preventive Services Task Force system was used to rate the strength of recommendations and the quality of evidence.

RESULTS

A total of 120 recommendations were proposed, covering 32 clinical topics and concerning preoperative evaluation (11 topics), perioperative (8 topics) and intraoperative (3 topics) management, and postoperative care (10 topics).

CONCLUSION

These recommendations should ease and promote the multidisciplinary management of older subjects with HF by integrating the expertise of different specialists. By providing a convenient list of topics of interest, they might assist in identifying unmet needs and research priorities.

Management of proximal femur fractures in the elderly: current concepts and treatment options

As one of the leading causes of elderly patients’ hospitalisation, proximal femur fractures (PFFs) will present an increasing socioeconomic problem in the near future. This is a result of the demographic change that is expressed by the increasing proportion of elderly people in society. Peri-operative management must be handled attentively to avoid complications and decrease mortality rates. To deal with the exceptional needs of the elderly, the development of orthogeriatric centres to support orthogeriatric co-management is mandatory. Adequate pain medication, balanced fluid management, delirium prevention and the operative treatment choice based on comorbidities, individual demands and biological rather than chronological age, all deserve particular attention to improve patients’ outcomes. The operative management of intertrochanteric and subtrochanteric fractures favours intramedullary nailing. For femoral neck fractures, the Garden classification is used to differentiate between non-displaced and displaced fractures. Osteosynthesis is suitable for biologically young patients with non-dislocated fractures, whereas total hip arthroplasty and hemiarthroplasty are the main options for biologically old patients and displaced fractures. In bedridden patients, osteosynthesis might be an option to establish transferability from bed to chair and the restroom. Postoperatively, the patients benefit from early mobilisation and early geriatric care. During the COVID-19 pandemic, prolonged time until surgery and thus an increased rate of complications took a toll on frail patients with PFFs. This review aims to offer surgical guidelines for the treatment of PFFs in the elderly with a focus on pitfalls and challenges particularly relevant to frail patients.

Platelet aggregometry for hip fracture surgery in patients treated with clopidogrel: a pilot study

Surgery for hip fractures should be performed within 48 h from patient's admission. However, several factors including chronic antiplatelet therapy could delay operation. Among the totality of patients taking clopidogrel, up to 30% are resistant to the drug and have a normal platelets reactivity. We propose thromboelastography (TEG) with an ADP Platelet Mapping assay kit to assess platelet aggregation, a safe tool that could help to avoid surgery delay in those patients treated with antiplatelet therapy. A patient's blood sample was collected for aggregometry. If MA-ADP and platelets aggregation (%) were within normal values, the patient was fit for immediate surgery with neuraxial anesthesia and ultrasound-guided nerve block. If one of the two parameters or both were deranged, a mortality risk assessment was estimated. In the low risk category, the patients waited till normalization of the parameters, whereas in the high-risk group a general anesthesia and peripheral antalgic block was carried out. Nine patients were enrolled. Four of them showed normal aggregometry and surgery was performed within 24 h from admission. Two patients were classified as high mortality risk and surgery was carried out under general anesthesia. Three patients awaited operation till normalization of parameters. No peri or post-operative complications were reported. An aggregometry-guided protocol can safely expedite hip fracture surgery in patients taking clopidogrel. Nonetheless, in presence of a normal platelets function, clinician can opt for a neuraxial instead of general anesthesia reducing the incidence of postoperative delirium and cognitive dysfunction.Trial registration: prospectively registered at clinicaltrials.gov (NCT04642209; date of registration: 23rd November 2020).

Efficacy of two integrated geriatric care pathways for the treatment of hip fractures: a cross-cultural comparison

INTRODUCTION

Many studies have focussed on the implementation and outcomes of geriatric care pathways (GCPs); however, little is known about the possible impact of clinical practices on these pathways. A comparison was made between two traumageriatric care models, one Swiss (CH) and one Dutch (NL), to assess whether these models would perform similarly despite the possible differences in local clinical practices.

MATERIALS AND METHODS

This cohort study included all patients aged 70 years or older with a unilateral hip fracture who underwent surgery in 2014 and 2015. The primary outcomes were mortality and complications. Secondary outcomes were time to surgical intervention, hospital length of stay (HLOS), differences in surgical treatment and the number of patients who needed secondary surgical intervention.

RESULTS

A total of 752 patients were included. No differences were seen in mortality at 30 days, 90 days and 1 year post-operatively. In CH, fewer patients had a complicated course (43.5% vs. 51.3%; p = 0.048) and fewer patients were diagnosed with delirium (7.9% vs. 18.3%; p < 0.01). More myocardial infarctions (3.8% vs. 0.4%; p < 0.01) and red blood cell transfusions (27.2% vs. 13.3%; p < 0.01) were observed in CH and HLOS in CH was longer (Mdn difference: - 2; 95% CI - 3 to - 2). Furthermore, a difference in anaesthetic technique was found, CH performed more open reductions and augmentations than NL and surgeons in CH operated more often during out-of-office hours. Also, surgery time was significantly longer in CH (Mdn difference: - 62; 95% CI - 67 to - 58). No differences were seen in the number of patients who needed secondary surgical interventions.

CONCLUSIONS

This cross-cultural comparison of GCPs for geriatric hip fracture patients showed that quality of care in terms of mortality was equal. The difference in complicated course was mainly caused by a difference in delirium diagnosis. Differences were seen in surgical techniques, operation duration and timing. These clinical practices did not influence the outcome.

The patterns and management of fracture patients under COVID-19 outbreak in China

Background

Currently, the perioperative care of fracture patients is compromised due to the outbreak of COVID-19 in China and the world. This study aims to assess the clinical features of fracture patients at our hospital during the COVID-19 outbreak and formulate the medical steps to ensure the effective treatment of fracture patients with minimal risk of infection to healthcare workers.

Methods

One hundred twelve patients with different fractures that were admitted to the orthopedics department of our hospital from January 24 to March 9 in 2020 were reviewed. Data including age, gender, injury location, admission time, operation time, discharge time were compared with fracture patients from the same period in 2019

Results

Compared to the same period in 2019, there is a 42% decrease in the number of fracture patients in 2020. Specifically, the incidences of forearm, thigh, hand, and foot fractures have increased during the COVID-19 outbreak, while other parts are less affected. The time from injury to hospitalization, the surgery wait time and time of discharge after surgery for patients with hip fractures were 2.9±7.1, 2.0±1.7 and 7.7±4.0 days respectively in 2019, which changed to 2.0±5.0, 4.5±4.0 and 10.6±4.2 days in 2020. Following the orthopedic treatment regimen followed at our hospital, all patients had non-life-threatening limb fractures. Six patients were operated in a negative pressure room, and emergency screening was completed for six patients. No patients were positive for COVID-19, and all were discharged safely without infection or other serious complications.

Conclusions

Hip fractures are highly prevalent during this epidemic. However, mandatory screening delays surgery by more than 48 hours. The orthopedic department should prioritize screening of emergency patients to minimize the risk of infection among other patients and medical personnel.

Development and validation of a nomogram to predict perioperative blood transfusion in patients undergoing total knee arthroplasty

Background

The need for a transfusion is one of the adverse events following total knee arthroplasty (TKA), and accurately predicting this need remains challenging for arthroplasty surgeons. The purpose of the present research is to study the preoperative predictors of transfusion risk in patients following TKA and develop a nomogram.

Methods

The nomogram was developed based on a training set of 5402 patients who underwent TKA at the Affiliated Hospital of Qingdao University between September 2013 and November 2018. The independent predictors of transfusion were identified by univariate, LASSO, and binary logistic regression analyses. Then, a nomogram was established based on these independent predictors. The area under the curve (AUC), calibration curve, and decision curve analysis (DCA) were selected to evaluate the nomogram. The results were validated using an independent set of 1116 patients who underwent TKA between December 2018 and September 2019. In addition, we also carried out subgroup analyses in the training and testing sets based on the independent predictors.

Results

Five independent predictors were identified by multivariate analysis and were used to establish the nomogram. The AUCs of the nomogram were 0.884 (95% CI: 0.865–0.903) and 0.839 (95% CI, 0.773–0.905) in the training and testing sets, respectively. In both the training and testing sets, the calibration curve indicated that the prediction by the nomogram was highly consistent with the actual observation, and the DCA indicated that the nomogram had a favorable level of clinical usefulness. In addition, the AUC of the nomogram was significantly higher than the AUC of any independent predictor for predicting transfusion risk following TKA, and the subgroup analysis showed good performance in 20 subgroups.

Conclusion

Lower preoperative Hb levels, simultaneous bilateral TKA, lower BMI, older age, and coronary heart disease were identified as independent predictors of postoperative transfusion in patients following TKA. A nomogram incorporating the above five predictors could accurately predict the transfusion risk.
