Abstract
PURPOSE Rivaroxaban is a potent, selective direct inhibitor of factor Xa. The aim of this study was to evaluate the therapy adherence, safety and efficacy of rivaroxaban therapy in reducing the risk of venous thromboembolism in patients undergoing elective hip or knee replacement. METHODS The prospective, post-marketing clinical trial was conducted on adult patients after knee or hip endoprosthesis. Data were collected at the baseline and three control visits (five days, a month and three months after the baseline). Morisky Medication Adherence Scale (MMAS-8) was used for evaluation of therapy adherence. RESULTS The study included 60 patients who received rivaroxaban therapy in a dose of 10 mg once a day. A low adherence to the drug was observed in 15% patients. All patients had an average MMAS-8 score in the range of high adherence 0.65 ± 0.90. Symptomatic venous thromboembolism was observed in two patients with numerous risk factors. No major bleeding was recorded during entire follow-up period. During the five-day postoperative in-hospital follow-up, signs of wound complications were recorded in 8 (13.3%) patients, and 4 (6.7%) of them underwent surgical revision of the wound. CONCLUSION Generally, there was high adherence to rivaroxaban therapy, but low adherence was present in 15% of patients. Rivaroxaban showed good safety and efficacy. However, high proportion of wound complications and patients needing surgical revision of the wound should be further evaluated through larger studies.

Abstract
BACKGROUND Hip fractures, most common in the geriatric age group, can develop proximal deep vein thrombosis (DVT). There is no consensus regarding the ideal method or duration of prophylaxis, particularly in a trauma patient. This study bridges this lacuna in data by making a random comparison between mechanical prophylaxis alone vis-a-vis combined with mechanical and Enoxaparin-based chemoprophylaxis. MATERIALS AND METHODS 75 Elderly hip trauma patients from January 2019 to October 2020 at a single tertiary care center were randomly allocated into two groups using the sequentially numbered opaque sealed envelope method (SNOSE): one (n=44) receiving Enoxaparin and Mechanical prophylaxis and another (n=31) receiving Mechanical prophylaxis alone. All patients underwent CT (computed tomography) venography to screen for proximal DVT between days 5 to 10 of injury. The primary outcomes were the incidence of proximal DVT and pulmonary embolism (PE), and safety outcomes (wound complications and adverse systemic events) were recorded during the treatment. RESULTS No symptomatic or asymptomatic proximal DVT and death incidence was reported in either group. One case of pulmonary embolism was seen in the combined prophylaxis group. There was no significant difference between the groups regarding the above-mentioned parameters mentioned. CONCLUSIONS There is no significant difference in the incidence of proximal DVT between mechanical alone and combined chemical-mechanical prophylaxis in elderly patients sustaining hip trauma. The incidence of proximal DVT can be reduced by mechanical prophylaxis alone. It was efficacious and safer than combined mechanical and enoxaparin prophylaxis in preventing venous thromboembolism in elderly hip trauma patients.

Abstract
OBJECTIVE A meta-analysis to determine if patients with varicose veins are at an increased risk of venous thromboembolism (VTE) when undergoing major lower limb arthroplasty. METHODS Medline, Embase, and Cochrane Library databases were searched using appropriate terms for studies that reported post-operative VTE in patients who had lower limb arthroplasty with any history of varicose veins. Methodological quality of included studies was quantified using the Risk of Bias (ROB) assessment tools. Findings were reported using the meta-analysis of observational studies in epidemiology (MOOSE) checklist. RESULTS A total of 129 studies were identified with 11 observational studies being eligible for inclusion. This consisted of 265,194 patients who underwent lower limb arthroplasty, 2188 of which had pre-existing varicose veins. Overall, VTE occurred in 1845 patients, and 122 cases had varicose veins present at time of arthroplasty. Meta-analysis indicates that patients undergoing lower limb arthroplasty with varicose veins are at increased risk of having a VTE, OR 2.37, 95% CI 1.54-3.63, (p < 0.001). One study evaluated if previous varicose veins surgery influenced the risk of VTE in arthroplasty patients, OR 0.96 (95% CI 0.7-1.28), p = 0.429. CONCLUSIONS Varicose veins and lower limb arthroplasty are known independent risk factors for VTE. There is a paucity of data regarding the risk of VTE in patients undergoing lower limb arthroplasty who have co-existing varicose veins. This meta-analysis shows that patients with varicose veins are at an increased risk of VTE when undergoing major lower limb arthroplasty. Further studies are required in order to determine if such patients should undergo varicose vein surgery before undertaking major lower limb joint replacement.

Abstract
BACKGROUND To analyze the risk factors for preoperative deep vein thrombosis (DVT) in knee osteoarthritis (OA) patients undergoing total knee arthroplasty (TKA). METHODS In this retrospective study, a total of 584 knee OA patients undergoing TKA were enrolled. General information, medical records and preoperative laboratory examination results of the patients were collected. According to the results of Doppler ultrasonography for the lower extremities, the patients were divided into DVT group and non-DVT group. Univariate and multivariate logistic regression were used to identify independent risk factors for preoperative DVT in knee OA patients undergoing TKA. RESULTS The incidence of DVT before TKA was 6.85% (40 cases). The increase of ESR (Erythrocyte Sedimentation Rate), platelet crit, IL-6 (Interleukin-6), and PCT (Procalcitonin) were associated with the development of DVT before TKA. Factors as coronary heart disease (CHD), diabetes mellitus (DM), Chronic Kidney Disease (CKD), NLR (ratio of neutrophils to lymphocytes), lower limb venous blood stasis, the time from onset to admission, RBC, PLT were identified by multivariate logistic regression to be the independent risk factors for preoperative DVT in knee OA patients undergoing TKA. CONCLUSIONS DM, CKD, CHD, increased in ESR, IL-6 and PCT, blood stasis of the lower extremities, increased in PLT, platelet crit and the time from onset to admission, decreased in RBC, were high risk factors for preoperative DVT in knee OA patients undergoing TKA.

Abstract
» In 2016, a total of 48,771 hospital-acquired conditions (HACs) were reported in U.S. hospitals. These incidents resulted in an excess cost of >$2 billion, which translates to roughly $41,000 per patient per HAC. » In the settings of total hip arthroplasty (THA) and total knee arthroplasty (TKA), increased age, a body mass index of >35 kg/m2, male sex, diabetes mellitus, electrolyte disturbances, and a history of anemia increase the likelihood of surgical site infections. » Institution-specific (surgical) risk factors such as increased tourniquet time, an operative time of >130 minutes, bilateral procedures, a femoral nerve block, and general anesthesia increase the risk of HACs in the settings of THA and TKA.

Abstract
BACKGROUND Venous thromboembolism (VTE) is a significant complication after joint arthroplasty. Diabetes is related to a few changes in coagulation and fibrinolysis that may lead to thrombophilia. We aimed to investigate the incidence of postoperative VTE and associated risk factors among patients with diabetes undergoing total hip (THA) or total knee anthroplasty (TKA) in a single centre in China. METHODS Patients with diabetes who underwent THA or TKA from January 2016 to December 2018 (n = 400) at Beijing Jishuitan Hospital were recruited in this study. Lower limb venous Doppler ultrasound was performed before and after surgery to confirm deep venous thrombosis (DVT). Computer tomography pulmonary angiography was done to confirm pulmonary embolism (PE) for those with new postoperative DVT and typical symptoms of PE. A multivariate logistic regression model was conducted to examine factors associated with the development of postoperative VTE. RESULTS The overall incidence of postoperative VTE in patients with diabetes after THA or TKA was 46.8 % (187 out of 400). Among the 187 VTE patients, 7.5 % (14 out of 187) had proximal vein thrombosis and 92.5 % (173 out of 187) had distal vein thrombosis. No PE occurred. Female patients and patients undergoing TKA had higher incidence of postoperative VTE. Patients who developed postoperative VTE were older, and had higher levels of preoperative D-Dimer and Caprini score. A high level of preoperative D-dimer (OR = 2.11, 95 %CI = 1.35-3.30) and the surgery of TKA (OR = 2.29, 95 %CI = 1.29-4.01) significantly increased the risk of developing postoperative VTE. Postoperative initiation of concomitant mechanical prophylaxis and low molecular weight heparin (LMWH) was protective for postoperative VTE (OR = 0.56, 95 %CI = 0.37-0.86). CONCLUSIONS VTE is common in patients with diabetes undergoing joint arthroplasty. Patients undergoing TKA or with a high level of preoperative D-dimer are at a considerable risk of developing postoperative VTE. There may be a protective role of postoperative initiation of concomitant mechanical prophylaxis and LMWH for VTE.

Abstract
PURPOSE The purpose of this systematic review was to elucidate the optimal age for patients undergoing total knee arthroplasty (TKA), to optimize the balance between the benefits and risks by analyzing patient-reported outcome measurements (PROM), revision rate, and mortality according to age. MATERIALS AND METHODS A rigorous and systematic approach was used and each of the selected studies was evaluated for methodological quality. Data were extracted according to the following: study design, patients enrolled, patient age at the time of surgery, follow-up period, PROM, revision rate, and mortality. RESULTS Thirty-nine articles were included in the final analysis. The results were inconsistent in the PROM analysis, but there was consensus that PROM were good in patients in their 70s . In the revision rate analysis, there was consensus that the revision rate tends to increase in TKA in younger patients, but no significant difference was observed in patients > 70 years of age. In the mortality analysis, there was consensus that the mortality was not significantly different in patients < 80 years of age, but tended to increase with age. CONCLUSION This systematic review shows that the PROM were good when TKA was performed in patients between 70 and 80 years of age; the best PROM could be achieved around 70 years of age, and no significant difference in the revision or mortality rates was observed between 70 and 80 years of age; however, mortality tended to increase with age. Therefore, the early 70s could be recommended as an optimal age to undergo TKA.

Abstract
BACKGROUND Risk for venous thromboembolism formation and the relationship to postoperative free flap venous congestion and flap failure have not been adequately evaluated in a trauma population. The authors aim to use the Caprini Risk Assessment Model to evaluate the association between venous thromboembolism risk and postoperative flap venous congestion following lower extremity free tissue transfer. METHODS A retrospective analysis was conducted of all patients who underwent lower extremity free flap reconstruction of traumatic defects at a single institution between 2007 and 2016. A Wilcoxon rank sum test was used for nonparametric analysis of aggregate Caprini Risk Assessment Model scores and flap outcomes. Flap venous congestion and failure rates as associated with the categorical variables underlying the Caprini Risk Assessment Model were further studied. Logistic regression was used to evaluate each of these outcomes and other flap-related covariates relative to the Caprini Risk Assessment Model categorical variables that had the greatest effect on our patient sample. RESULTS One hundred twelve patients underwent lower extremity free flap reconstruction. One hundred eight free flaps were analyzed. Eight patients were excluded. The majority of patients were male (75.9 percent) and required reconstruction because of acute trauma (68.1 percent versus 31.9 percent for chronic wounds). There was no statistically significant association found between age, body mass index, or timing of trauma versus venous congestion, flap failure, or other flap-related covariates. CONCLUSION In patients with significantly elevated Caprini Risk Assessment Model scores, there was no significant association between venous thromboembolism risk and flap failure following free tissue reconstruction of lower extremities.

Abstract
BACKGROUND Total joint arthroplasty is one of the most common options for end stage osteoarthritis of major joints. However, we must take into account that thrombosis after hip/knee arthroplasty may be related to mutations in genes encoding for blood coagulation factors and immune reactions to anticoagulants [heparin-induced thrombocytopenia (HIT)/thrombosis]. Identifying and characterizing genetic risk should help to develop diagnostic strategies or modify anticoagulant options in the search for etiological mechanisms that cause thrombophilia following major orthopedic surgery.
AIM To evaluate the impact of patients’ coagulation profiles and to study specific pharmacologic factors in the development of post-arthroplasty thrombosis.
METHODS In 212 (51 male and 161 female) patients that underwent primary total hip arthroplasty (100) or total knee arthroplasty (112) due to osteoarthritis during a period of 1 year, platelet counts and anti-platelet factor 4 (PF4)/heparin antibodies were evaluated pre/postoperatively, and antithrombin III, methylenetetrahydrofolate reductase, factor V and prothrombin gene mutations were evaluated preoperatively. In a minimum follow-up of 3 years, 196 patients receiving either low-molecular-weight heparins (173) or fondaparinux (23) were monitored for the development of thrombocytopenia, anti-PF4/heparin antibodies, HIT, and thrombosis.
RESULTS Of 196 patients, 32 developed thrombocytopenia (nonsignificant correlation between anticoagulant type and thrombocytopenia, P = 0134.) and 18 developed anti-PF4/heparin antibodies (12/173 for low-molecular-weight heparins and 6/23 for fondaparinux; significant correlation between anticoagulant type and appearance of antibodies, P = 0.005). Odds of antibody emergence: 8.2% greater in patients receiving fondaparinux than low-molecular-weight heparins. Gene mutations in factor II or V (two heterozygotes for both factor V and II) were identified in 15 of 196 patients. Abnormal low protein C and/or S levels were found in 3 of 196 (1.5%) patients, while all patients had normal levels of von Willebrand factor, lupus anticoagulant, and antithrombin III. Four patients developed HIT (insignificant correlation between thrombocytopenia and antibodies) and five developed thrombosis (two had positive antibodies and two were heterozygotes for both factor II & V mutations). Thrombosis was not significantly correlated to platelet counts or HIT. The correlation of thrombosis to antibodies, factor II, factor V was P = 0.076, P = 0.043, P = 0.013, respectively.
CONCLUSION Screening of coagulation profile, instead of platelet monitoring, is probably the safest way to minimize the risk of post-arthroplasty thrombosis. In addition, fondaparinux can lead to the formation of anti-PF4/heparin antibodies or HIT.

Abstract
Venous thromboembolism (VTE) is a leading cause of mortality during the perioperative period, with individuals who have undergone hip and knee arthroplasty at the highest risk for VTE. The American College of Chest Physicians recommends 35 days of postoperative thromboprophylaxis and the use of intermittent pneumatic compression (IPC) therapy for mechanical compression after major orthopedic surgery. However, little research has described adherence to these recommendations during recovery at home. The purpose of this cross-sectional descriptive study was to describe thromboprophylaxis prescription, use, and education among patients discharged home after major orthopedic surgery. We surveyed patients within 2 years of major orthopedic surgery. A total of 388 subjects completed the survey. More than three-quarters of respondents reported a thromboprophylaxis duration <35 days. Most (93.8%) respondents were prescribed a pharmacologic agent, while 55.9% were prescribed mechanical compression therapy. Of the respondents who were prescribed mechanical compression therapy, 13.4% were prescribed IPC. Adherence to mechanical compression therapy was moderate, with 63% of respondents wearing mechanical compression therapy ≥75% of the time. The results of this study suggest a need for increased duration of thromboprophylaxis and increased use of IPC in the outpatient setting. Additional research describing prescribers' perceptions of thromboprophylaxis is also needed.

Abstract
To determine the incidence of DVT and to evaluate the risk factors of DVT under LMWH prophylaxis in patients with thoracolumbar fractures caused by high‑energy injuries postoperatively. A total of 534 patients from January 2016 to November 2019 were included in this retrospective study. Medical record data, including demographic data, perioperative variables, and laboratory results, were collected. LMWH prophylaxis was used for DVT in all the patients. The incidence and risk factors of DVT after surgery were identified by logistic regression analysis and receiver operating characteristic (ROC) curve analysis. The overall incidence of postoperative DVT was 18.91% (101/534). Three patients (0.56%) had proximal DVT and ninety-eight (18.35%) patients had distal DVT. The incidence of postoperative DVT in patients with thoracic fractures was 26.80% and 15.50% with lumbar fractures. The multivariate analysis showed that six risk factors increased the incidence of postoperative DVT, including advanced age, decreased lower extremity motor, blood transfusion, duration of bed rests, fibrinogen (FIB), and D-dimer. The ROC analysis indicated that the diagnostic value of D-dimer was highest whose area under the ROC curves (AUC) value was 0.754. Despite LMWH prophylaxis, the risk of postoperative DVT is still very high, especially in thoracic fracture. Advanced age, decreased lower extremity motor, blood transfusion, duration of bed rests, FIB, and D-dimer are risk factors for DVT. Moreover, the diagnostic value of D-dimer is the highest among these factors.

Mackowiak J, Jones JT, Dasa V. A comparison of 4-year total medical care costs, adverse outcomes, and opioid/prescription analgesic use for 3 knee osteoarthritis pain treatments: Intra-articular hyaluronic acid, intra-articular corticosteroids, and knee arthroplasty. Semin Arthritis Rheum 2020; 50:1525-1534. [PMID: 32088013 DOI: 10.1016/j.semarthrit.2020.01.003] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/08/2019] [Revised: 01/03/2020] [Accepted: 01/13/2020] [Indexed: 01/01/2023]
Abstract
OBJECTIVES To compare the medical costs associated with treatments for knee osteoarthritis (OA): intra-articular corticosteroids (ICS) and intra-articular hyaluronic acid (IHA) primarily, and ICS/IHA vs knee arthroplasty (TKA) secondarily. METHODS This was a retrospective analysis of an insurance claims database. Eligible members had diagnosed OA and no claims for ICS, IHA, or TKA during the 6-18-month look-back period. Cohorts of interest over the 4-year observation period were: patients who received ICS only, those who received IHA only, and those who received TKA only. Outcomes assessed included: (1) total allowed medical costs, (2) claims for pre-specified, treatment-related adverse outcomes and costs, and (3) opioid and/or prescription analgesic use and costs. Data extraction began on the date of the first ICS, IHA, or TKA in 2013 until December 31, 2017. RESULTS Of the 260,828 patients who qualified, 126,831 were taking monotherapy (IHA=3703, ICS=117,588, TKA = 5540). Adjusted 4-year per patient per month (PPPM) costs were lowest in the IHA cohort ($733); PPPM costs were $1230 in the ICS cohort and $1548 in the TKA cohort. A smaller percentage of patients in the IHA (7.1%) vs ICS (8.4%) or TKA cohort (11.8%) experienced any of the pre-specified adverse outcomes. Adverse outcome-related costs in the IHA cohort were lower ($19.91) than costs in the ICS ($32.18) and TKA cohorts ($31.12). Per-patient opioid and analgesic prescriptions were consistently and significantly lower in the IHA (range, 0.70-0.96) vs ICS cohort (range, 2.0-2.26) for Years 1 through 4. Usage rates were significantly lower in the IHA cohort vs TKA cohort in Year 1 (0.96 vs 4.77) and not different in Years 2 through 4 (TKA range, 0.76-1.08). In Year 1, opioid and prescription analgesic costs were significantly lower in the IHA vs ICS and TKA cohorts ($3.45 vs $11.14 and $12.82). After Year 1, opioid and prescription analgesic costs were significantly higher in the ICS (range, $13.83-15.96) vs IHA (range, $3.02-3.87) and TKA cohorts (range, $3.43-4.97). CONCLUSIONS Patients in the IHA cohort had lower total medical care costs, fewer adverse outcomes, and lower use/costs of opioids and prescription analgesics vs patients in the ICS and TKA cohorts. Reducing total medical care costs and minimizing opioid/analgesic use should be a treatment goal when selecting therapies for patients with knee OA.

Abstract
BACKGROUND Prophylactic anticoagulant therapy is recommended to reduce the risk of venous thromboembolism (VTE) after total hip or knee arthroplasty, and has become the standard of care. Rivaroxaban is a novel oral medication that directly inhibits factor Xa for the prevention and treatment of thromboembolic conditions. METHOD A meta-analysis of randomized controlled trials (RCTs) was performed to determine the efficacy and safety of rivaroxaban after total hip arthroplasty (THA) and total knee arthroplasty (TKA) surgery. We reviewed several databases including PubMed, the Cochrane Library, Embase and the US trial registry to detect appropriate RCTs for our meta-analysis. The primary efficacy outcome of this meta-analysis was the combination of any deep-vein thrombosis (DVT), non-fatal pulmonary embolism (PE), and death from any cause. The main safety outcome was bleeding events which included significant bleeding events, clinically relevant insignificant bleeding events, or minor events. Other end points were the number of patients who received blood transfusion the volume of transfused whole blood or red blood cells, and the volume of postoperative drainage. RESULT Thirteen RCTs were included in this meta-analysis. This meta-analysis showed that the overall rate of VTE events, DVT, PE, and death were 1%, 6%, < 1% and < 1%, respectively, for patients receiving treatment with rivaroxaban after THA and TKA surgery. The subgroup analysis demonstrated rivaroxaban had more superior effects in THA patients. The pooled analysis of bleeding events showed that the overall rate of major bleeding events, overt bleeding events associated with fall in Hb of > 2 g/DL, clinically overt bleeding events leading to transfusion of > 2 units of blood, clinically overt bleeding events leading to further surgeries, and non-major bleeding events were < 1%, < 1%, < 1%, < 1%, and 3%, respectively. CONCLUSION This is the first systematic review of the literature providing incidence of efficacy and safety outcomes for thromboprophylaxis in THA and TKA patients. Moreover, this meta-analysis showed that rivaroxaban had more superior effect in THA patients.

Abstract
IMPORTANCE The associations of a family history of venous thromboembolism (FH-VTE) with postoperative venous thromboembolism (VTE) and major bleeding after joint replacement surgical procedures are unknown. OBJECTIVE To determine the risk of VTE and major bleeding in patients after primary hip or knee replacement surgical procedures. DESIGN, SETTING, AND PARTICIPANTS Cohort study using nationwide population-based databases of Swedish patients without a history of VTE who underwent joint replacement surgical procedures. Patients who had primary hip or knee replacement surgical procedures between July 1, 2005, and August 31, 2012, were identified. Patients born after 1931 without previous VTE were identified in the Swedish Multi-Generation Register. Only individuals with at least 1 parent and 1 full sibling alive between 1964 and the date for the surgical procedure were included. The data analysis was performed from September 1, 2017, to June 15, 2018. EXPOSURES Family history of VTE in a parent and/or a full sibling before the date of the surgical procedure. MAIN OUTCOMES AND MEASURES Venous thromboembolism and major bleeding within 90 days of the surgical procedure. RESULTS Of 69 505 study participants, 37 989 (54.7%) were women, and the median (interquartile range) age at the date of discharge was 65 (59-70) years. A total of 803 of 69 505 (1.2%) patients experienced postoperative VTE and 1285 (1.8%) experienced major bleeding. The cumulative VTE risk for those with FH-VTE was 231 of 15 858 (1.5%) and for those without an FH-VTE was 572 of 53 647 (1.1%) (P < .001). The cumulative bleeding risk for those with FH-VTE was 261 of 15 858 (1.6%) and for those without an FH-VTE was 1024 of 53 647 (1.9%) (P = .03). There was an association of patients with an FH-VTE who had increased VTE risk (adjusted hazard ratio [HR], 1.36; 95% CI, 1.17-1.59) and reduced bleeding risk (adjusted HR, 0.84; 95% CI, 0.74-0.97). There was an interaction between time after discharge and FH-VTE regarding VTE and major bleeding. An FH-VTE was not associated with VTE after discharge during the first week (HR, 1.13; 95% CI, 0.86-1.49). After 7 days from discharge, FH-VTE was associated with VTE (HR, 1.49; 95% CI, 1.24-1.79). An FH-VTE reduced major bleeding risk during the first 7 days after discharge (HR, 0.78; 95% CI, 0.66-0.91) but not thereafter (HR, 1.10; 95% CI, 0.84-1.44). Postoperative VTE heritability (SE) was 20% (6%). CONCLUSIONS AND RELEVANCE Familial and most likely genetic factors appear to affect VTE and major bleeding risk following hip and knee replacement surgical procedures. Prolonged VTE prophylaxis might be beneficial in predisposed individuals. There may be a possible evolutionary advantage of prothrombotic genes protecting against traumatic bleeding.

Abstract
Background Low-molecular-weight heparin (LMWH) is a recommended anticoagulant for thromboprophylaxis after major orthopedic surgery. Dabigatran etexilate is an oral anticoagulant recognized as noninferior to LMWH. We aimed to assess the incidence of symptomatic venous thromboembolic events (VTEs) after discharge in patients who underwent joint replacement, using a hospital registry. Patients and methods Patients who underwent total knee and hip arthroplasty between September 2011 and March 2015 were selected. Subcutaneous enoxaparin (30 mg twice daily) was given during hospitalization. At discharge, patients received either enoxaparin 30 mg twice daily/40 mg once daily or dabigatran 220 mg/150 mg once daily. Patients were seen or called at 2, 6, and 12 weeks after surgery. Outcomes were the number of VTEs, including deep venous thrombosis, pulmonary embolism, and the number of major/minor bleeding events after discharge. Results After discharge, 1468 patients were prescribed enoxaparin and 904 dabigatran (1396 total knee arthroplasty and 976 total hip arthroplasty patients). Mean age was 66±10 years, and 60% were female. The cumulative incidence of VTEs during the 12-week follow-up was 0.7%. One patient sustained a VTE during the switch window. Seven patients sustained a pulmonary embolism (0.3%). There was no statistical difference between the total knee arthroplasty and total hip arthroplasty groups. The incidence of major and minor bleeding events during follow-up was 0.3% and 30.3%, respectively. These events had a higher incidence in the dabigatran group compared to the enoxaparin group after discharge (p<0.05), but not between knee and hip replacement groups for major bleeding events. Conclusion A pharmaceutical prophylaxis protocol using LMWH and dabigatran during the post-discharge period resulted in low incidences of VTE and equivalence between treatments. However, the increased number of major and minor bleeding events in patients taking dabigatran is of concern regarding the safety and needs to be evaluated using analyses adjusted for risk factors.

Abstract
BACKGROUND Heart failure (HF) is a common comorbidity in the aging population and they will require major elective surgery. The purpose of this study is to determine if HF is a risk factor for adverse perioperative outcomes and short-term complications following total knee arthroplasty. METHODS The American College of Surgeons National Surgical Quality Improvement Program database was utilized to identify all patients who underwent total knee arthroplasty for osteoarthritis from 2008 to 2014. Any diagnosis other than osteoarthritis was excluded. A total of 111,634 patients were identified and 251 of these patients had a preoperative diagnosis of HF. The main outcomes included operative time, lengths-of-stay, discharge disposition, return to operating room, readmission, and short-term complications, including death. RESULTS Patients with HF were found to have longer hospital stays (β = 0.59, 95% confidence interval [CI] 0.12-1.06) following total knee arthroplasty, and were more likely to return to the operating room (odds ratio 2.00, 95% CI 1.01-3.94) and be readmitted (OR 1.88, 95% CI 1.21-2.94). In addition, HF was found to be a risk factor for 1 or more complications (OR 1.41, 95% CI 1.05-1.90), wound dehiscence (OR 4.86, 95% CI 1.68-14.03), and myocardial infarction (OR 4.81, 95% CI 1.90-12.16) postoperatively. CONCLUSION Patients with HF are more likely to have a longer length-of-stay, return to the operating room, and be readmitted. Additionally, they have a higher risk for at least one postoperative complication, myocardial infarction, and wound dehiscence.

Abstract
SummaryFamilial clustering of venous thromboembolism (VTE) was described as far back as 1905 by Briggs. Although Egeberg discovered inherited deficiency of antithrombin in 1965, it was not until Dahlback discovered resistance to activated protein C in 1993 that it became clear that genetic factors are common risk factors of VTE. Several genes have been linked to familial aggregation of VTE and genome-wide association studies have found several novel gene loci. Still, it has been estimated that much of the heritability for VTE remains to be discovered. Family history (FH) of VTE is therefore still important to determine whether a patient has an increased genetic risk of VTE. FH has the potential to represent the sum of effects and interactions between environmental and genetic factors. In this article the design, methodology, results, clinical and genetic implications of FH studies of VTE are reviewed. FH in first-degree relatives (siblings and/or parents) is associated with a 2–3 times increased familial relative risk (FRR). However, the FRR is dependent on age, number of affected relatives, and presentation of VTE (provoked/unprovoked). Especially high familial risks are observed in individuals with two or more affected siblings (FFR> 50). However, the familial risk for recurrent VTE is much lower or non-significant. Moreover, FH of VTE appears mainly to be important for venous diseases (i. e. VTE and varicose veins). The familial associations with other diseases are weaker. In conclusion, FH of VTE is an important research tool and a clinically potential useful risk factor for VTE.

Abstract
PURPOSE the main purpose of our study was to compare patient compliance with the orally administered new oral anticoagulants (NOCs) dabigatran and rivaroxaban compared with subcutaneously injected fondaparinux after major orthopaedic surgery, and to assess patient preference for the oral vs subcutaneous administration route. METHODS prophylactic antithrombotic drug therapy with dabigatran (group D; GD, n=32 patients), rivaroxaban (group R; GR, n=38 patients) or fondaparinux (group F; GF, n=30 patients), to prevent deep vein thrombosis, was started immediately after surgery in 100 patients submitted to total hip arthroplasty. RESULTS the patients had a mean age of 68.7±11 years and 62% were female. In GD, 87.5% of patients indicated that they preferred oral intake of medications to subcutaneous injection (12.5%). In GR, 84.2% declared a preference for oral administration over subcutaneous injection (15.8%). In GF, a surprisingly high proportion of patients (73.3%; p < 0.001) declared that they preferred subcutaneous administration of medications over the oral route (26.7%). Overall, the rate of compliance with antithrombotic drug therapy was very high, at 99%. CONCLUSIONS intake of the NOAs dabigatran and rivaroxaban following hospital discharge is entirely the responsibility of the patient; a high level of patient compliance with these drugs must therefore be demonstrated in order for them to become well accepted within the medical community. The results of this study showed a very high level of compliance both with orally and subcutaneously administered drugs. LEVEL OF EVIDENCE Level I, randomized clinical study.

Abstract
Venous thromboembolic disease (VTE) comprises pulmonary embolism (PE) and deep vein thrombosis (DVT), and causes morbidity and mortality, particularly in trauma and orthopaedic patients. Prevalence of 0.9% and 1.2% respectively are reported, with mortality rates up to 13.8%. Chemical thromboprophylactic agents including low molecular weight heparin (LMWH) are considered cost effective in reducing VTE risk. Evidence for anti-platelets including Aspirin for VTE prophylaxis is less compelling and is not supported as monotherapy. There has been no published data on patient compliance with LMWH in trauma outpatients. We aimed to determine whether trauma outpatients accept LMWH after discussing their VTE risk and the evidence for prophylaxis. For those accepting prophylaxis, we also investigated their compliance for the duration of immobilisation. Lower limb injured patients treated with external immobilisation over a 6 month period at our major trauma centre were included. On completion of immobilisation, they were requested to complete a 17-point questionnaire. Patients declining injectable subcutaneous LMWH as prophylaxis were offered Aspirin 75 mg as a second line agent. Seventy-five questionnaires were completed and five were excluded. Nineteen patients required surgical intervention for their injury, 51 were managed non-operatively. Thirty-one patients accepted LMWH and 30 chose Aspirin as an alternative. Nine patients declined or were not commenced on prophylaxis. Nineteen reported no missed Aspirin doses and 25 reported no missed LMWH doses. No patients reported missed doses due to pain, side effects or cessation of treatment for another reason. The mean average pain score recorded on the VAS was 3.8. No patients in the study were diagnosed with a VTE. LMWH is a recognised chemical thromboprophylactic and is well tolerated by patients for VTE risk reduction in lower limb immobilised outpatients. With poor evidence supporting Aspirin as a solo prophylactic agent, our local policy has withdrawn Aspirin for this purpose.

Dua A, Desai SS, Lee CJ, Heller JA. National Trends in Deep Vein Thrombosis following Total Knee and Total Hip Replacement in the United States. Ann Vasc Surg 2016; 38:310-314. [PMID: 27531085 DOI: 10.1016/j.avsg.2016.05.110] [Citation(s) in RCA: 33] [Impact Index Per Article: 4.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/04/2016] [Revised: 05/05/2016] [Accepted: 05/11/2016] [Indexed: 11/16/2022]
Abstract
BACKGROUND Total knee replacement (TKR) and total hip replacement (THR) are associated with an increased risk of deep vein thrombosis (DVT). Advances in DVT prophylaxis over the past decade have led to a decrease in DVT-related morbidity, but gender, racial, and other demographic factors that contribute to a higher risk of DVT are incompletely characterized. This study aimed to determine the incidence of DVT over the past decade and identify factors that were associated with an increased risk of DVT. METHODS Patients who underwent TKR or THR between 2001 and 2011 were identified using the National Inpatient Sample. For patients who developed a DVT, their demographics (including age, gender, and race), comorbidities, and subsequent outcomes (including length of stay [LOS] and mortality) were determined. Differences between patients who developed a DVT and those who did not were determined using multivariate regression analysis. A Mann-Kendall analysis was done to evaluate all trends. RESULTS Between 2001 and 2011, a total of 1.1 million patients underwent TKR, and 550,000 underwent THR. The overall incidence of DVT decreased for TKR from 0.86% in 2001 to 0.45% in 2011 and decreased for THR from 0.55% to 0.24% for the same period. Patients who developed a DVT after TKR were older (67.7 vs. 66.8, P < 0.001); more likely to be African American (P < 0.001); and more likely to have significant comorbidities including congestive heart failure, peripheral artery disease, and end-stage renal disease. Findings were similar for patients who developed a DVT after THR. Mortality was significantly greater for patients who developed a DVT (0.4% for TKR and 1.7% for THR), with an almost double LOS. CONCLUSIONS A focus on DVT prophylaxis may have decreased national rates of DVT after TKR and THR. Older patients, African Americans, and patients with more comorbidities appear to be especially at risk for DVT. Mortality is almost 4 to 8 times higher for patients with DVT, and LOS is double. A focus on DVT prophylaxis and perhaps more aggressive management of the at-risk population may further help decrease the rate of DVT.

[PMID: 26765646 DOI: 10.1016/s2352-3026(15)00228-8] [Citation(s) in RCA: 47] [Impact Index Per Article: 5.2] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/30/2015] [Revised: 10/20/2015] [Accepted: 10/21/2015] [Indexed: 02/06/2023]
Abstract
BACKGROUND Venous thromboembolism is a major global health problem that is often secondary to other clinical situations. Many studies have investigated the association between venous thromboembolism and heart failure, but have yielded inconsistent findings. We aimed to quantify the absolute and relative risks (RR) for venous thromboembolism in patients with heart failure after hospital admission. We also assessed rates of venous thromboembolism in patients in different settings. METHODS In this systematic review and meta-analysis, we searched for studies investigating the risk of venous thromboembolism in patients in hospital with heart failure. We searched for studies published between Jan 1, 1955, and March 31, 2015, in PubMed, Embase, Evidence-Based Medicine Reviews, Allied and Complementary Medicine Database, Ovid HealthSTAR, Global Health, Ovid Nursing Database, Web of Science, CINAHL Plus, ProQuest Central, Conference Papers Index, BIOSIS Previews, and ClinicalTrials.gov. All cohort studies and subgroup analyses of randomised controlled trials (RCTs) were eligible for inclusion if they reported venous thromboembolism rates (number of events per follow-up period) or RR estimates. We extracted data from published reports and contacted the corresponding authors of records with insufficient quantitative data. RRs and 95% CIs were pooled using a random-effects model. This study is registered with PROSPERO, number CRD42014015504. FINDINGS Of 8673 records identified, we included 71 studies with data from 88 cohorts in our analysis, with 59 cohorts included in the assessment of venous thromboembolism rates and 46 cohorts included in the meta-analysis of heart failure and risk of venous thromboembolism. Venous thromboembolism rates varied widely in patients in hospital with heart failure from different settings. The overall median symptomatic venous thromboembolism rate was 2·48% (IQR 0·84-5·61); rates was were 3·73% (1·05-7·31) for patients who did not receive thromboprophylaxis and 1·47% (0·64-3·54) for those who did. Overall, patients with heart failure in hospital had an RR of 1·51 (1·36-1·68) for venous thromboembolism. The overall I(2) statistic was 96·1% and there was no evidence of publication bias (Egger's test, p=0·46). INTERPRETATION Heart failure is a common independent risk factor for venous thromboembolism. Thromoboprophylaxis should be considered in clinical practice for high-risk patients. FUNDING National Natural Science Foundation.

Abstract
INTRODUCTION Venous thromboembolism (VTE) is a common complication after total hip arthroplasty (THA) or total knee arthroplasty (TKA) and may be the cause for a secondary PE and associated morbidity/mortality. We performed a systematic literature review of risk factors and risk reduction of VTE after THA or TKA. MATERIALS AND METHODS A systematic search of PubMed database, the Cochrane Library, OVID MEDLINE and American Academy of Orthopaedic Surgeons (AAOS), without restriction of publication data and language, was conducted. We performed a meta-analysis of ten factors for VTE after THA or TKA. Four authors independently assessed data extraction and quality of the studies using the Newcastle-Ottawa Scale (NOS) as quality assessment tool. Assessment of heterogeneity and analysis of data were operated by Review Manager 5.2.9. RESULTS Fourteen retrospective case-control or prospective cohort studies, which included 18,075 patients who developed VTE after THA or TKA of a total of 1,723,350 cases, were selected. Our results demonstrated that, among all ten factors investigated, 3 main risk factors were significantly associated with VTE after THA or TKA: history of VTE (RR > 10.6), varicose vein (RR > 2.7) and congestive cardiac failure (RR 2). There was also an increase of VTE risk ranging from 8 to 30 % for female gender < age (≥80) < hypertension < (active) cancer < obesity (BMI ≥ 30) < (black) race. Data analysis revealed that diabetes mellitus had no significant relationship with VTE after THA or TKA. CONCLUSIONS This study highlighted the role of nine significant risk factors in the development of VTE after THA or TKA. Among all risk factors, history of VTE seems the one main indication for more potent anticoagulation. All other risk factors need to be considered and discussed with patients individually and balanced against the risk of bleeding and infection. Individual patient risk assessment, rather than a "blanket policy", is considered the best management strategy before deciding on the type of chemical prophylaxis.

Abstract
Aim To investigate the potential role of a novel electrostimulation device in augmenting the femoral vein venous blood flow following total knee replacement surgery. Material and methods A total of 30 consecutive patients undergoing total knee replacement were allocated to receive either peroneal nerve electrostimulation plus low molecular weight heparin and below-knee compression stockings (Group 1, electrostimulation group, n = 15, mean age: 63.40 ± 5.91 years, male: female ratio 9:6) or low molecular weight heparin and below-knee compression stockings alone (Group 2, control group, n = 15, mean age: 63.86 ± 7.47 years, male: female ratio 8:7). Electrostimulation was performed for 1 h in every 4 h after the operation. Peak blood velocity in the femoral vein was evaluated with Duplex ultrasonongraphy in supine position. Presence of leg edema and calf diameter was also taken into consideration as outcome measures, which were recorded both before surgery and at the time of discharge from hospital. Results Postoperative peak blood flow velocity in the femoral vein was significantly higher in electrostimulation group compared to control group (17.46 ± 2.86 cm/s vs. 13.84 ± 3.58 cm/s, p < 0.02). Electrostimulation group achieved a significant increase in peak blood flow velocity in the femoral vein after the operation (mean increase 67.48 ± 17.38%, p < 0.001). Conclusion Electrostimulation of the common peroneal nerve enhanced venous flow in the lower limb and may potentially be of use as a supplementary technique in deep venous prophylaxis following lower limb orthopedic operations.

Abstract
People with chronic venous disease are at high risk for developing venous leg ulcers. Inflammation is posited as a pathological factor for this chronic condition as evidenced by persistently elevated skin temperature. As part of a larger trial to test the effects of a cooling regimen on leg ulcer prevention, the objective of this preliminary study was to evaluate the first 30 days of intense daily cooling. Compared to a placebo control cuff, a gel cuff applied to the most severely affected lower leg skin for 30 min daily showed no statistically significant differences between temperatures taken in the home at baseline compared to those measured at the 1 month follow up visit. There were also no differences in temperatures noted between the two groups, although the temperatures in the treatment group were lower 30 min after treatment, an indication of adherence. There was no discernable decrease or increase in temperature at a given time point during the 30 day treatment period compared to the control group. It may be better to have patients monitor skin temperature on a daily basis and then apply the cuff as necessary, rather than requiring daily cooling based on baseline measurement. This "prn" approach may provide a sufficient cooling milieu to prevent escalation of inflammation and thwart ulcer occurrence or recurrence. Clinical trials registration #NCT01509599.

Abstract
Objective: Deep venous thrombosis (DVT) and pulmonary embolus (PE) are serious problems for patients admitted to the hospital with stroke, subarachnoid hemorrhage (SAH), intracerebral hemorrhage (ICH) and transient ischemic attack (TIA). The purpose of this paper is to further understand the factors that place certain patients at increased risk of DVT/PE. Methods: At a 600 bed hospital, a retrospective analysis of data from 2613 patients admitted with a diagnosis of stroke, SAH, ICH or TIA in the time range 1/2008 through 3/2012 was carried out. The data was taken from the hospital’s Get with the Guidelines database and included 28 variables. These included initial NIH stroke scale, length of stay, heart failure, ambulatory by day 2 after admission, altered mental status,and renal failure among others. Multiple analyses were carried out to determine whether there were univariable or multivariable effects of any of the factors on the risk for DVT/PE. Results: The risk of DVT/PE was highest in patients with SAH and ICH and smallest with TIA. Multivariable analyses were performed and revealed only altered level of consciousness or heart failure as significant risks for DVT/PE. With the limited available data, administration of subcutaneous heparin or other chemoprophylaxis did not reduce the risk of DVT/PE. Conclusion: Although many of the variables used to describe the stroke patient are correlated, in multivariable analyses only heart failure and altered level of consciousness were important risk factors for DVT/PE. The risk of DVT/PE was 7 fold greater in patients in patients with both of these risk factors.

Abstract
BACKGROUND This study aims to determine the incidence of pulmonary embolism (PE) in trauma and orthopedic patients within a regional tertiary referral center and its association with the pattern of injury, type of treatment, co-morbidities, thromboprophylaxis and mortality. METHODS All patients admitted to our institution between January 2010 and December 2011, for acute trauma or elective orthopedic procedures, were eligible to participate in this study. Our cohort was formed by identifying all patients with clinical features of PE who underwent Computed Tomography-Pulmonary Angiogram (CT-PA) to confirm or exclude the clinical suspicion of PE, within six months after the injury or the surgical procedure.Case notes and electronic databases were reviewed retrospectively to identify each patient's venous thromboembolism (VTE) risk factors, type of treatment, thromboprophylaxis and mortality. RESULTS Out of 18,151 patients admitted during the study period only 85 (0.47%) patients developed PE (positive CT-PA) (24 underwent elective surgery and 61 sustained acute trauma). Of these, only 76% of the patients received thromboprophylaxis. Hypertension, obesity and cardiovascular disease were the most commonly identifiable risk factors. In 39% of the cases, PE was diagnosed during the in-hospital stay. The median time of PE diagnosis, from the date of injury or the surgical intervention was 23 days (range 1 to 312). The overall mortality rate was 0.07% (13/18,151), but for those who developed PE it was 15.29% (13/85). Concomitant deep venous thrombosis (DVT) was identified in 33.3% of patients. The presence of two or more co-morbidities was significantly associated with the incidence of mortality (unadjusted odds ratio (OR) = 3.52, 95% confidence interval (CI) (1.34, 18.99), P = 0.034). Although there was also a similar clinical effect size for polytrauma injury on mortality (unadjusted OR = 1.90 (0.38, 9.54), P = 0.218), evidence was not statistically significant for this factor. CONCLUSIONS The incidence of VTE was comparable to previously reported rates, whereas the mortality rate was lower. Our local protocols that comply with the National Institute for Health and Clinical Excellence (NICE) guidelines in the UK appear to be effective in preventing VTE and reducing mortality in trauma and orthopedic patients.

Abstract
The risk of venous thromboembolism following major orthopaedic procedures, such as joint arthroplasty and hip fracture surgery, are well recognised and represent one of the major challenges in orthopaedic practice, having in mind the increasing number of arthroplasties of the hip and knee done worldwide per year and their successful outcome. This potentially fatal complication remains a challenge in orthopaedic practice. The percentage of patients in whom antithrombotic prophylaxis has not been administrated or has been inadequate may reach 50%. Until recently, anticoagulant prophylaxis with low molecular weight heparins (LMWHs) has been a "gold standard". LMWHs are indirect inhibitors of the clotting factors Xa and thrombin and are administered by daily subcutaneous injection. Their efficacy has been proven in numerous clinical trials and the rate of complications with their use is relatively low. However these compounds are associated with a failure rate and are inconvenient to administer, requiring subcutaneous injection, leading to inadequate compliance. For these reasons postoperative thrombembolism continues to occur in up to 10% of this patient population. Recently, novel oral anticoagulants have been introduced into practice for thromboprophylaxis after joint arthroplasy and hip fracture surgery. These drugs are direct thrombin inhibitors (dabigatran) or direct factor Xa inhibitors (rivaroxaban, apixaban and edoxaban). These oral drugs have the same efficacy as the LMWHs with the same or slightly more clinically significant haemorrhage as their main side effect. Their ease of administration and favourable clinical profile makes them an important addition to the therapeutic armamentarium available for venous thromboprophylaxis. In this paper we review the aetiology and pathogenesis of venous thromboembolism and present the various alternatives for its prevention after major orthopaedic surgical procedures with emphasis on the new oral drugs.

Abstract
OBJECTIVE To evaluate the association between tourniquet and total operative time during total knee arthroplasty and the occurrence of deep vein thrombosis. METHODS Seventy-eight consecutive patients from our institution underwent cemented total knee arthroplasty for degenerative knee disorders. The pneumatic tourniquet time and total operative time were recorded in minutes. Four categories were established for total tourniquet time: <60, 61 to 90, 91 to 120, and >120 minutes. Three categories were defined for operative time: <120, 121 to 150, and >150 minutes. Between 7 and 12 days after surgery, the patients underwent ascending venography to evaluate the presence of distal or proximal deep vein thrombosis. We evaluated the association between the tourniquet time and total operative time and the occurrence of deep vein thrombosis after total knee arthroplasty. RESULTS In total, 33 cases (42.3%) were positive for deep vein thrombosis; 13 (16.7%) cases involved the proximal type. We found no statistically significant difference in tourniquet time or operative time between patients with or without deep vein thrombosis. We did observe a higher frequency of proximal deep vein thrombosis in patients who underwent surgery lasting longer than 120 minutes. The mean total operative time was also higher in patients with proximal deep vein thrombosis. The tourniquet time did not significantly differ in these patients. CONCLUSION We concluded that surgery lasting longer than 120 minutes increases the risk of proximal deep vein thrombosis.
