Abstract
BACKGROUND The Caprini score is a validated scale that calculates a patient's 30-day venous thromboembolism (VTE) risk based on their comorbidities. The American Society of Plastic Surgeons published VTE prophylaxis recommendations in 2011 based on the Caprini score, but these recommendations are vague and up to physician interpretation. The purpose of this study is to evaluate postoperative outcomes after the application of strict guidelines using the Caprini score with specific VTE chemoprophylaxis benchmarks on plastic surgery patients. METHODS A retrospective cohort analysis was performed on all plastic surgery patients who underwent surgery between July 2019 and July 2021. Patients between July 2019 and June 2020 were not subjected to any specific VTE prophylaxis protocol, while patients from July 2020 to July 2021 were subjected to the newly created VTE prophylaxis protocol. Every patient received a calculated Caprini score at their preoperative history and physical. The primary outcomes measured include hematoma, deep vein thrombosis (DVT) and pulmonary embolism (PE). RESULTS Four hundred forty-one patients with 541 procedures were included in this study, with 275 patients in the "before" group and 166 patients in the "after" group. A total of 78.6% of patients received chemoprophylaxis in the "before" group compared with 20% in the "after" group. There was no significant difference in postoperative complications between the two groups including PE or DVT ( P = 0.2684 and 0.2696, respectively), with a trend toward hematoma formation in the "before" group ( P = 0.1358). After the application of evidence-based VTE guidelines, the patients stayed fewer days in the hospital (0.4 vs 0.7 days, P = 0.0085) and were less likely to be readmitted (2.4% vs 6.5%, P = 0.0333). The average cost per patient in the "before" group was $9.11 with a total cost of $3022.90. The average cost per patient in the "after" group was $4.23 with a total cost of $867.94 ( P = 0.032). CONCLUSIONS Our strict application of the Caprini score significantly and safely limited the number of patients receiving postoperative VTE chemoprophylaxis and showed no significant difference in postoperative hematoma, DVT, or PE.

Postoperative Timing of Chemoprophylaxis and Its Impact on Thromboembolism and Bleeding Following Major Abdominal Surgery: A Multicenter Cohort Study. World J Surg 2023; 47:1174-1183. [PMID: 36806555 PMCID: PMC10070293 DOI: 10.1007/s00268-023-06899-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 12/18/2022] [Indexed: 02/21/2023]
Abstract
BACKGROUND Major abdominal surgery is associated with bleeding and venous thromboembolism (VTE) risks. Chemoprophylaxis prevents VTE but increases bleeding risk. When compared with pre- and intra-operative chemoprophylaxis, recent evidence suggests that starting chemoprophylaxis postoperatively lowers the risk of bleeding without compromising VTE protection. This study investigates whether an optimal window exists in the postoperative period for initiating chemoprophylaxis in patients undergoing major abdominal surgery. METHODS Analysis of pooled data from four multicenter PROTECTinG studies, which investigated the timing of perioperative chemoprophylaxis on bleeding and VTE outcomes following major abdominal surgery. Patients that commenced chemoprophylaxis postoperatively were separated into quartiles based on timing of administration within the first 24 h post-surgery. RESULTS Overall, 4729 (Abdominal visceral resection N = 668, cholecystectomies N = 573, major ventral hernia repair N = 1701, antireflux surgery N = 1787) consecutive patients had chemoprophylaxis commenced within 24 h following elective surgery. Baseline characteristics were comparable between quartiles. Across quartiles and within each procedural type, the timing of starting chemoprophylaxis was not associated with bleeding (2.6, 1.7, 2.7 and 3.2%, p = 0.130) or clinical VTE (0.8, 0.2, 0.8 and 0.5%, p = 0.131), and did not predict their occurrences on multivariate analysis. CONCLUSION Chemoprophylaxis can be safely started at any time within 24 h post-skin closure in major abdominal surgery, without affecting bleeding or VTE risks. This finding encourages the standardization of chemoprophylaxis timing in the postoperative period to pre-defined times during the day to improve workflow efficiency and chemoprophylaxis compliance.

A Propensity-Matched Analysis of the Postoperative Venous Thromboembolism Rate After Pancreatoduodenectomy Based on Operative Approach. J Gastrointest Surg 2022; 26:623-634. [PMID: 34757511 DOI: 10.1007/s11605-021-05191-y] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/09/2021] [Accepted: 10/23/2021] [Indexed: 01/31/2023]
Abstract
BACKGROUND The use of minimally invasive approaches for pancreatoduodenectomy has increased in recent years, but the risk of postoperative VTE is undefined. We aimed to compare venous thromboembolism (VTE) rates after open and minimally invasive pancreatoduodenectomy using an administrative dataset. METHODS Patients who underwent pancreatoduodenectomy within the National Surgical Quality Improvement Program targeted pancreatectomy database (2016-2018) were identified. VTE was compared between patients who underwent open or minimally invasive pancreatoduodenectomy directly and after propensity score matching 1:1 for demographics, comorbidities, and peri-/intra-operative factors. RESULTS A total of 12,227 patients underwent pancreatoduodenectomy during the study period (open: n = 11,217; minimally invasive: n = 1010). Before matching, the VTE rate was higher among patients who underwent minimally invasive pancreatoduodenectomy (5.2% vs. 3.8%, p = 0.033), and minimally invasive resection was independently associated with VTE (OR = 1.46, 95%CI = 1.09-2.06). After matching, there were 916 patients per group without differences in demographics or comorbidities. Patients who underwent minimally invasive pancreatoduodenectomy had longer median operative times (422 vs. 348 min). The VTE rate remained higher following minimally invasive pancreatoduodenectomy after matching (5.1% vs. 2.9%, p = 0.018), mainly driven by a higher DVT rate (3.9% vs. 1.7%, p = 0.005). CONCLUSIONS Minimally invasive pancreatoduodenectomy is associated with a higher postoperative VTE rate compared to open pancreatoduodenectomy.

Abstract
Background: Venous thromboembolism (VTE) is a common disease in Latin American settings. Implementation of international guidelines in Latin American settings requires additional considerations. Objective: To provide evidence-based guidelines about VTE prevention for Latin American patients, clinicians, and decision makers. Methods: We used the GRADE ADOLOPMENT method to adapt recommendations from 2 American Society of Hematology (ASH) VTE guidelines (Prevention of VTE in Surgical Patients and Prophylaxis for Medical Patients). ASH and 12 local hematology societies formed a guideline panel composed of medical professionals from 10 countries in Latin America. Panelists prioritized 20 questions relevant to the Latin American context. A knowledge synthesis team updated evidence reviews of health effects conducted for the original ASH guidelines and summarized information about factors specific to the Latin American context, that is, values and preferences, resources, accessibility, feasibility, and impact on health equity. Results: The panel agreed on 21 recommendations. In comparison with the original guideline, 6 recommendations changed direction and 4 recommendations changed strength. Conclusions: This guideline ADOLOPMENT project highlighted the importance of contextualization of recommendations in other settings, based on differences in values, resources, feasibility, and health equity impact.

Abstract
BACKGROUND Venous thromboembolism is a significant cause of postoperative death and morbidity. While prophylactic and treatment regimens exist, they usually come with some risk of clinically relevant bleeding and, thus, must be considered carefully for each individual patient. METHODS This special topic article represents a review of current evidence regarding venous thromboembolism risk, biology, and prevention in plastic surgery patients. The specific types and duration of available prophylaxis are also reviewed. The balance of venous thromboembolism risk must be weighed against the risk of hemorrhage. RESULTS Though alternatives exist, the most validated risk assessment tool is the 2005 modification of the Caprini Risk Assessment Model. Controversies remain regarding recommendations for outpatient and low risk cosmetic patients. The authors additionally make recommendations for high-risk patients regarding the use of tranexamic acid, estrogen therapy, anesthesia, and prophylaxis regimens. CONCLUSION Our profession has made great strides in understanding the science behind venous thromboembolism, risk stratification for patients, and prophylactic regimens; yet, continued studies and definitive data are needed.

Abstract
OBJECTIVES Venous thromboembolism (VTE) prophylaxis regimes frequently have a wide variation in application. Nepean acute surgical unit was established in 2006 as a novel model for emergency surgical care. As part of the model's rollout, there were several areas of clinical management targeted for improvement, one being VTE prophylaxis compliance. It was decided all patients older than 18 years treated for a variety of acute surgical conditions within the acute surgical unit should be administered routine VTE prophylaxis with heparin and compression stockings. A novel multifaceted intervention was implemented at the time to achieve this goal. The primary aim of this study was to determine VTE prophylaxis administration rates before and after this intervention. METHODS A before-after study conducted as a retrospective review of medical records of all patients 18 years or older, having an appendicectomy in 3 periods: Before acute surgical unit (ASU) (November 2004 to October 2006), Early ASU (November 2006 to October 2008), and Established ASU (January 2012 to December 2013). Outcomes were mechanical and pharmacological VTE prophylaxis administration rates for each group. RESULTS There were 1149 patients included in the study: Before ASU, 167; Early ASU, 375; and Established ASU, 607. There was a significant stepwise increase in parmacological VTE prophylaxis administration: Before ASU, 54.5%; Early ASU, 74.7%; and Established ASU, 96.9% (Before versus Early: odds ratio [OR], 2.46; 95% confidence interval [CI], 1.68-3.61; P < 0.001; Early versus Established: OR, 10.500; 95% CI, 6.29-17.53; P < 0.001). Mechanical VTE prophylaxis was significantly increased in the established group (Before versus Established: OR, 47.18; 95% CI, 25.61-86.91; P < 0.001). CONCLUSIONS There was a significant increase in VTE prophylaxis administration after the implementation of our multifaceted intervention. Allocating a responsible provider dedicated to VTE prophylaxis prescription and compliance checking was a key component to this intervention.

Abstract
Background: The aim of this study was to determine the anti-factor Xa levels in patients receiving enoxaparin sodium for venous thromboembolism prophylaxis in the intensive care unit (ICU). Patients and methods: Using a cross-sectional study methodology, 73 ICU patients receiving 40 mg enoxaparin sodium daily were enrolled in this study. Anti-factor Xa levels were measured following the second dose. Prophylactic and subprophylactic groups of patients were compared for age, sex, weight, body mass index, total bilirubin, serum albumin, and APACHE II score. Results: Anti-factor Xa levels were prophylactic (0.2–0.6 IU/mL) in 44 (60.3%) patients and subprophylactic (<0.2 IU/mL) in 29 (39.7%) patients. The mean (SD) actual delivered dose of enoxaparin per kilogram body weight was significantly higher, at 0.59 (0.11) mg/kg in the prophylactic group compared to 0.53 (0.13) mg/kg in the subprophylactic group (p = 0.043). The subprophylactic group had significantly lower serum albumin levels compared to the prophylactic group. The total bilirubin levels were not found to be significantly different between the two groups (p = 0.110). Conclusion: A fixed prophylactic 40 mg dose of enoxaparin was associated with a high proportion of subprophylactic anti-factor Xa levels. Weight-based dose and serum albumin level were independent predictors of achieving the prophylactic target range. How to cite this article: Baloo MM, Scribante J, Perrie H, Calleemalay D, Omar S.

Abstract
Background The optimum chemical venous thromboembolism (VTE) prophylactic agents following total hip and knee replacement (THR and TKR) remain unknown. NICE recommends multiple agents, including direct oral anticoagulants (DOACs), low-molecular weight heparin (LMWH), and aspirin. We assessed whether VTE prophylaxis affected the risk of VTE and adverse events following primary THR and TKR. Materials and methods We reviewed 982 elective primary THRs (59%) and TKRs (41%) at a large tertiary centre during 2018. The primary outcome was any VTE (DVT and/or PE) within 90-days. Secondary outcomes were adverse events within 90-days (major bleeding and wound complications). The association between VTE prophylaxis and outcomes was assessed. Results The overall prevalence of VTE and adverse events were 2.7% (n = 27) and 15.2% (n = 136) respectively. The most common agents used were DOAC ± LMWH (50.7%, n = 498), followed by aspirin ± LMWH (35.5%, n = 349) and LMWH alone (4.7%, n = 46). The risk of VTE (aspirin ± LMWH = 3.7%, DOAC = 2.0%, LMWH = 2.2%) was not significantly different between agents (p = 0.294). The risk of any adverse event was significantly higher (p < 0.001) with aspirin ± LMWH (16.1%; n = 56) and LMWH (28.3%; n = 13) compared with DOACs ± LMWH (7.0%; n = 35) in TKRs only, there was no differences between agents for adverse events in THRs (p = 0.644). Conclusions Choice of thromboprophylaxis did not influence the risk of VTE following primary THR and TKR. DOACs (+/- LMWH) were associated with the lowest risk of adverse events. Large multicentre trials are still needed to assess the efficacy and safety of these agents following THR and TKR.

Abstract
BACKGROUND Deep vein thrombosis (DVT) is among the most frequent complications of surgery. This study aimed to analyse the incidence and risk factors of lower extremity venous thrombosis after urologic surgery. MATERIALS AND METHODS This prospective two-centre study was conducted from August 2019 to January 2020. Patients who underwent urological procedures were enrolled. The primary endpoint was the detection of asymptomatic or symptomatic DVT of the lower extremity within 7 days after surgery. Univariate and least absolute shrinkage and selection operator (LASSO) logistic regression analyses were performed. RESULTS Fifty-six of 1011 patients developed DVT. In the univariate analysis, Barthel Index ≤40, d-dimer level ≥0.5 mg/L and age ≥60 years (p < 0.001) were identified as the most significant risk factors. The LASSO logistic regression model identified nine factors: age, history of DVT, lymph node dissection, perioperative steroid use, Caprini score, Barthel Index, D-dimer level, cystectomy, and prostatectomy. CONCLUSION Our study used the LASSO logistic regression model to provide reliable data on the risk factors for DVT after comprehensive urologic surgery. The incidence of DVT in this group was 5.54%. This might facilitate individualised anticoagulant management in patients undergoing urological procedures.

Abstract
PURPOSE Venous thromboembolism (VTE) is the most common preventable cause of hospitalization-associated mortality. In the absence of optimal prophylaxis and depending on the type of surgery and patient-related factors, the risk of developing VTE increases by 10% to 50%. We aimed to assess VTE risk and thromboprophylaxis among surgical patients hospitalized at surgical wards of Tikur Anbessa Specialized Hospital (TASH). Addis Ababa, Ethiopia. MATERIALS AND METHODS A retrospective cross-sectional study was conducted from September 1, 2018 to February 28, 2019. Data were collected using a pretested observational checklist which is prepared based on the VTE Caprini risk assessment model. Then, the collected data were checked for completeness and finally entered and analyzed using Statistical Package for Social Sciences (SPSS) version 25. RESULTS Out of 155 admitted patients, almost equal numbers of males (49.68%) and females (50.32%) participated in the study with a mean age of 41.87±16.84 and an age range of 13 to 89 years. Undergoing major surgery, resting in bed for more than 3 days and having acute infections (including pneumonia) were the most frequently seen VTE risk factors. Most of the study participants (135, 87.10%) were at risk of developing VTE (>1 Caprini risk score), and 47.11% were in the highest risk category (≥5 Caprini score). The maximum and minimum total risk scores were 19 and 1, respectively with a mean score of 4.53±2.31. Among patients who were at risk of developing VTE and eligible for thromboprophylaxis, only 17.78% received thromboprophylaxis and two ineligible patients received prophylaxis. Parental unfractionated heparin twice or three times per day was the most widely used thromboprophylaxis regimen. A total of 29 (18.71%) patients had one or more contraindication(s) for thromboprophylaxis and three of them took prophylaxis despite the contraindications. Only 3 (1.93%) patients admitted to surgical wards developed VTE during hospitalization. CONCLUSION As per the Caprini risk assessment model, the majority of surgical patients treated at TASH were at risk of developing VTE. However, thromboprophylaxis was underutilized. The incidence of VTE was 1.93% in our study.

Abstract
Heparins show great anticoagulant effect with few side effects, and are administered by subcutaneous or intravenous route in clinics. To improve patient compliance, oral administration is an alternative route. Nonetheless, oral administration of heparins still faces enormous challenges due to the multiple obstacles. This review briefly analyzes a series of barriers ranging from poorly physicochemical properties of heparins, to harsh biological barriers including gastrointestinal degradation and pre-systemic metabolism. Moreover, several approaches have been developed to overcome these obstacles, such as improving stability of heparins in the gastrointestinal tract, enhancing the intestinal epithelia permeability and facilitating lymphatic delivery of heparins. Overall, this review aims to provide insights concerning advanced delivery strategies facilitating oral absorption of heparins.

Abstract
BACKGROUND Venous thromboembolism (VTE) associated with surgery can cause serious comorbidities or death and imposes a substantial economic burden to society. The study examined VTE cases after surgery to determined how this condition imposed an economic burden on patients based on the national health insurance reimbursement database. Methods: This retrospective analysis adopted the public payer's perspective. The direct medical cost was estimated using data from the national claims database of Vietnam from Jan 1, 2017 to Sep 31, 2018. Adult patients who underwent surgeries were recruited for the study. Patients with a diagnostic code of up to 90 days after surgery were considered VTE cases with the outcome measure being the surgery-related costs within 90 days. RESULTS The 90-day cost of VTE patients was found to be US$2,939. The rate of readmission increased by 5.4 times, the rate of outpatient visits increased by 1.8 times and total costs over 90 days in patients with VTE undergoing surgery increased by 2.2 times. Estimation using propensity score matching method showed that an increase of US$1,019 in the 90-day cost of VTE patients. CONCLUSION The VTE-related costs can be used to assess the potential economic benefit and cost-savings from prevention efforts.

Abstract
BACKGROUND Pulmonary embolism (PE)-related death is a component of the primary outcome in many venous thromboembolism (VTE) studies. The absence of a standardized definition for PE-related death hampers study outcome evaluation and between-study comparisons. OBJECTIVES To summarize definitions for PE-related death used in recent VTE studies and to assess the PE-related death rate. PATIENTS/METHODS A systematic literature search was conducted on 26 April 2018 from 1 January 2014 up to the search date in MEDLINE, Embase, and CENTRAL. Cohort studies and randomized trials in which PE-related death was included in the primary outcome were eligible. Screening of titles, abstracts, and full-text articles, and data extraction were independently performed in duplicate by two authors. Study outcomes included the definition for PE-related death, VTE case-fatality rate, and death due to PE rate. Descriptive statistics were used to analyze the data. RESULTS Of the 6807 identified citations, 83 studies were included of which 27% were randomized trials, 31% were prospective, and 42% retrospective cohort studies. Thirty-five studies (42%) had a central adjudication committee. Thirty-eight (46%) reported a definition for PE-related death of which the most frequently used components were "autopsy-confirmed PE" (50%), "objectively confirmed PE before death" (55%), and "unexplained death" (58%). Median VTE case-fatality rate was 1.8% (interquartile range, 0.0-13). CONCLUSIONS Only half of the included studies reported definitions for PE-related death, which were very heterogeneous. Case-fatality rate of VTE events varied widely across studies. Standardization of the definition and guidance on adjudication and reporting of PE-related death is needed.

Abstract
OBJECTIVE To investigate the prevalence of and risk factors for Venous Thromboembolism (VTE) in postoperative patients. METHODS This descriptive, cross-sectional, retrospective study was conducted from August 2016 to October 2016 at two university hospitals and one public hospital. Total 217,354 patients records who underwent surgery in between 2010 and 2015 were examined. The study sample consisted of 123 patients who had postoperative venous thrombosis and pulmonary embolism, and whose discharge details, consultation data, diagnostic reports, and tests were examined in detail. RESULTS The prevalence of VTE in postoperative patients was 5.6/10,000. The mean age of the patients was 60.22±18.56 years. Of 123 patients, 51.20% were male, 30.90% were smokers, 46.30% had a comorbid disease, and 27.60% were diagnosed with cancer. Of the patients who had postoperative VTE, 65.0% had major surgery. Pharmacologic thromboprophylaxis was used in only 24.4% of patients (n=30). CONCLUSION The prevalence of VTE in the present study is lower than that in other studies. Because surgery is a risk factor for VTE, patients who will be operated should be assessed. Considering the present results, we can assume that patients' conditions are not being assessed appropriately. In addition, findings indicate that a standard for preventing VTE has not yet been established.

Abstract
BACKGROUND Hospital-associated venous thromboembolism (HA-VTE) is a serious adverse event, preventable with appropriate care during and post-admission. Accurate measurement of in-hospital and post-discharge incidences is essential for implementation and evaluation of prevention strategies and monitoring. AIMS To estimate in-hospital and post-discharge diagnosed VTE, trends and risk factors. METHODS This was a population-based study in New South Wales, Australia, using linked hospital admission and emergency department data for 2010-2013 of adult patients with a minimum stay of 48 h. HA-VTE were diagnosed in-hospital or post-discharge (within 90 days). Multi-level modelling schemes produced adjusted rates and ratios for patient, admission and hospital-related characteristics. RESULTS From 1 865 059 admissions, the HA-VTE incidence rate was 9.7 per 1000 admissions; 71% were diagnosed post-discharge, and 4.3% died with a greater risk for VTE diagnosed in hospital compared to post-discharge (8.4% vs 2.6%, P < 0.001). Compared with surgical patients, medical patients developed fewer HA-VTE (IRR = 0.60, 95% CI: 0.58-0.63) but were more likely to be diagnosed post-discharge (OR = 2.19; 95% CI: 2.00-2.40). HA-VTE increased 6.5% over the period, driven by the 44% increase in in-hospital diagnoses and not by the 9% decrease in post-discharge diagnoses. CONCLUSIONS HA-VTE is a continuing burden, and diagnosis after recent hospital discharge is notably high. Incidence varies across patients and facilities, highlighting the need for individual VTE risk assessment. Inclusive measures and routine monitoring of HA-VTE incidence and mortality are essential for implementing best practice and assessing effectiveness of prevention strategies.

Abstract
Background Venous thromboembolism (VTE) is a major complication after lower-limb arthroplasty that increases costs and reduces patient’s quality of life. Using anticoagulants for 10–35 days following arthroplasty is the standard prophylaxis, but its cost-effectiveness after accounting for bleeding complications remains unproven. Methods A comprehensive, clinical model of VTE was created using the incidences, clinical effects (including bleeding), and costs of VTE and prophylaxis from randomized controlled trials, meta-analyses, and large observational studies. Over 50 years, the total health care costs and clinical impact of three prophylaxis strategies, that are as follows, were compared: low-molecular-weight heparin (LMWH) alone, intermittent pneumatic compression (IPC), and IPC with LMWH (IPC+LMWH). The cost per VTE event that was avoided and cost per quality-adjusted life year (QALY) gained in both the US and Australian health care settings were calculated. Results For every 2,000 patients, the expected number of VTE and major bleeding events with LMWH were 151 and 6 in the USA and 160 and 46 in Australia, resulting in a mean of 11.3 and 9.1 QALYs per patient, respectively. IPC reduced the expected VTE events by 11 and 8 in the USA and Australia, respectively, compared to using LMWH alone. IPC reduced major bleeding events compared to LMWH, preventing 1 event in the US and 7 in Australia. IPC+LMWH only reduced VTE events. Neither intervention substantially impacted QALYs but both increased QALYs versus LMWH. IPC was cost-effective followed by IPC+LMWH. Conclusion IPC and IPC+LMWH are cost-effective versus LMWH after lower-limb arthroplasty in the USA and Australia. The choice between IPC and IPC+LMWH depends on expected bleeding risks.

Abstract
BACKGROUND Current international clinical practice guidelines do not adequately address all clinical scenarios in the management of venous thromboembolism (VTE), and no comprehensive Australian guidelines exist. AIMS To identify areas of uncertainty in VTE management and whether self-reported practice is consistent with guidelines. METHODS We conducted an Australian cross-sectional online survey consisting of 53 questions to investigate doctors' VTE management practices. The survey was distributed to consultant and trainee/registrar haematologists and respiratory physicians with the aid of participating medical societies. RESULTS A total of 71 haematologists and 110 respiratory physicians responded to the survey. The majority of survey respondents were 31-50-years old and worked in teaching hospitals and in the acute care setting. Under-treatment was reported for high-risk pulmonary embolism (PE) and duration of anticoagulation for first-episode unprovoked PE (32 and 83% respectively). Over-treatment was reported in areas of thrombolysis for intermediate-risk PE (16%) and duration of anticoagulation for first-episode provoked PE (41%). Uncertainty and variations in doctors' management approaches were also found. CONCLUSION This survey demonstrated significant over-treatment, under-treatment and variability in the practice of VTE management. The findings highlight the need for the development and implementation of national guidelines for the management of VTE in Australia.

Abstract
Background
Venous thromboembolism (VTE) is a common vascular complication of noncardiac surgery.
Methods
We evaluated national trends in perioperative in-hospital VTE incidence, management, and outcomes using a large database of hospital admissions from the United States. Patients aged ≥ 45 years undergoing major noncardiac surgery from 2005 to 2013 were identified from the National Inpatient Sample. In-hospital perioperative VTE was defined as lower extremity deep vein thrombosis (DVT) or pulmonary embolism (PE), and the incidence was evaluated over time. Multivariable regression models with demographics and comorbidities as covariates were generated to estimate adjusted odds ratios (aOR).
Results
Major noncardiac surgery was performed in 9,431,442 hospitalizations that met inclusion criteria, and perioperative VTE occurred in 99,776 patients (1,057 per 100,000), corresponding to an annual incidence of ≈53,000 after applying sample weights. Over time, perioperative VTE per 100,000 surgeries increased by 135 (95% confidence interval [CI]: 107–163), from 925 in 2005 to 1,060 in 2013 (
p
for trend <0.001; aOR [for 2013 vs. 2005]: 1.22, 95% CI: 1.19–1.26), due to increases in nonfatal VTE rates (from 840 [per 100,000 surgeries] in 2005 to 987 in 2013;
p
for trend <0.001). Perioperative VTE occurred most frequently in patients undergoing thoracic (2.0%) and vascular surgery (1.8%). Mortality was higher in patients with VTE than those without VTE (aOR: 3.12, 95% CI: 3.05–3.20).
Conclusion
Perioperative VTE occurs in approximately 1% of patients ≥45 years undergoing major noncardiac surgery, with increasing incidence of nonfatal VTE over time.

Abstract
BACKGROUND Data on hospital-acquired venous thromboembolism (HA-VTE) incidence, case fatality rate and variation amongst patient groups and health providers is lacking. We aim to explore HA-VTE incidences, associated mortality, trends and variations across all acute hospitals in New South Wales (NSW)-Australia. METHODS A population-based study using all admitted patients (aged 18-90 with a length of stay of at least two days and not transferred to another acute care facility) in 104 NSW acute public and private hospitals during 2002-2009. Poisson mixed models were used to derive adjusted rate ratios (IRR) in presence of patient and hospital characteristics. RESULTS Amongst, 3,331,677 patients, the incidence of HA-VTE was 11.45 per 1000 patients and one in ten who developed HA-VTE died in hospital. HA-VTE incidence, initially rose, but subsequently declined, whereas case fatality rate consistently declined by 22 % over the study period. Surgical patients were 128 % (IRR = 2.28, 95 % CI: 2.19-2.38) more likely to develop HA-VTE, but had similar case fatality rates compared to medical patients. Private hospitals, in comparison to public hospitals had a higher incidence of HA-VTE (IRR = 1.76; 95 % CI: 1.42-2.18) for medical patients. However, they had a similar incidence (IRR = 0.91; 95 % CI: 0.75-1.11), but a lower mortality (IRR = 0.59; 95 % CI: 0.47-0.75) amongst surgical patients. Smaller public hospitals had a lower HA-VTE incidence rate compared to larger hospitals (IRR < 0.68) but a higher case fatality rate (IRR > 1.71). Hospitals with a lower reported HA-VTE incidence tended to have a higher HA-VTE case fatality rate. CONCLUSION Despite the decline in HA-VTE incidence and case fatality, there were large variations in incidents between medical and surgical patients, public and private hospitals, and different hospital groups. The causes of such differences warrant further investigation and may provide potential for targeted interventions and quality improvement initiatives.

Abstract
Diagnostic data routinely collected for hospital admitted patients and used for case-mix adjustment in care provider comparisons and reimbursement are prone to biases. We aim to measure discrepancies, variations and associated factors in recorded chronic morbidities for hospital admitted patients in New South Wales (NSW), Australia. Of all admissions between July 2010 and June 2014 in all NSW public and private acute hospitals, admissions with over 24 hours stay and one or more of the chronic conditions of diabetes, smoking, hepatitis, HIV, and hypertension were included. The incidence of a non-recorded chronic condition in an admission occurring after the first admission with a recorded chronic condition (index admission) was considered as a discrepancy. Poisson models were employed to (i) derive adjusted discrepancy incidence rates (IR) and rate ratios (IRR) accounting for patient, admission, comorbidity and hospital characteristics and (ii) quantify variation in rates among hospitals. The discrepancy incidence rate was highest for hypertension (51% of 262,664 admissions), followed by hepatitis (37% of 12,107), smoking (33% of 548,965), HIV (27% of 1500) and diabetes (19% of 228,687). Adjusted rates for all conditions declined over the four-year period; with the sharpest drop of over 80% for diabetes (47.7% in 2010 vs. 7.3% in 2014), and 20% to 55% for the other conditions. Discrepancies were more common in private hospitals and smaller public hospitals. Inter-hospital differences were responsible for 1% (HIV) to 9.4% (smoking) of variation in adjusted discrepancy incidences, with an increasing trend for diabetes and HIV. Chronic conditions are recorded inconsistently in hospital administrative datasets, and hospitals contribute to the discrepancies. Adjustment for patterns and stratification in risk adjustments; and furthermore longitudinal accumulation of clinical data at patient level, refinement of clinical coding systems and standardisation of comorbidity recording across hospitals would enhance accuracy of datasets and validity of case-mix adjustment.

Abstract
OBJECTIVE To determine the incidence and assess risk factors for the development of VTE among patients undergoing major pelvic surgery for prostate and bladder cancer in an Australian tertiary referral center. PATIENTS AND METHODS Consecutive patients undergoing major pelvic uro-oncologic surgery, namely radical cystectomy and radical prostatectomy over a five-year period (2009-2013) were identified. Patient variables and types of thromboprophylaxis (pharmacological and/or mechanical) used in this patient cohort were collected for analyses as predictive factors. RESULTS The overall incidence of VTE was 1.8%. Patients undergoing radical cystectomy were more likely to suffer a VTE event compared to patients having radical prostatectomy. In this cohort, the risk factors for VTE include, prolonged operative time of greater than 4 hours (h), lymph node dissection (LND) and patients requiring blood transfusions. CONCLUSION Patients undergoing major pelvic uro-oncologic surgery have an approximately 1.8% risk of developing VTE. Risk factors identified in this study should be used to guide the use of early and prolonged thromboprophylaxis.
