Abstract
BACKGROUND Hospital-acquired thrombosis (HAT) is a leading cause of preventable death and disability worldwide. HAT includes any venous thromboembolic (VTE) event occurring in-hospital or within 90-days of hospitalisation. Despite availability of evidence-based guidelines for HAT risk assessment and prophylaxis, guidelines are still underutilised. AIM To determine the proportion of patients who developed HAT that could have been potentially prevented with appropriate VTE risk assessment and prophylaxis at a large public hospital in New Zealand. Additionally, the predictors of VTE risk assessment and thromboprophylaxis were examined. METHOD VTE patients admitted under general medicine, reablement, general surgery, or orthopaedic surgery service were identified using ICD-10-AM codes. Data were collected on patient characteristics, VTE risk factors, and the thromboprophylaxis regimen prescribed. The hospital VTE guidelines were used to determine rates of VTE risk assessment and the appropriateness of thromboprophylaxis. RESULTS Of 1302 VTE patients, 213 HATs were identified. Of these, 116 (54%) received VTE risk assessment, and 98 (46%) received thromboprophylaxis. Patients who received VTE risk assessment were 15 times more likely to receive thromboprophylaxis (odds ratio [OR] = 15.4; 95% CI 7.65-30.98) and 2.8 times more likely to receive appropriate thromboprophylaxis (OR = 2.79; 95% CI 1.59-4.89). CONCLUSION A large proportion of high-risk patients who were admitted to medical, general surgery and reablement services and who developed HAT did not receive VTE risk assessment and thromboprophylaxis during their index admission, demonstrating a significant gap between guideline recommendations and clinical practice. Implementing mandatory VTE risk assessment and adherence to guidelines to improve thromboprophylaxis prescription in hospitalised patients may help reduce the burden of HAT.

J Surg Res 2023; 289:135-140. [PMID: 37119614 DOI: 10.1016/j.jss.2023.03.041] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/30/2022] [Revised: 03/20/2023] [Accepted: 03/26/2023] [Indexed: 05/01/2023]
Abstract
INTRODUCTION In adult populations, postoperative venous thromboembolism (VTE) is a reported complication of up to 8% of elective laparoscopic splenectomy (LS) cases. VTE is a rare event in the pediatric population, affecting less than 1% of all pediatric surgical patients. We hypothesized that pediatric patients are at a higher risk of postoperative VTE after undergoing elective LS relative to other laparoscopic procedures and may warrant prophylactic treatment. MATERIALS AND METHODS We queried the American College of Surgeons National Surgical Quality Improvement Program-Pediatric (NSQIP-P) database from 2012 to 2020. Patients were identified using the Current Procedural Terminology code 38120 and only elective cases were analyzed. RESULTS The incidence of VTE in all pediatric patients undergoing surgery in the American College of Surgeons NSQIP-P database was 0.13%. The incidence of VTE in pediatric patients undergoing elective laparoscopic abdominopelvic procedures was 0.17%. There were seven total cases of VTE (0.41%) in pediatric patients undergoing elective LS, more than twice the rate of the general population (P = 0.001). Eighty percent of pediatric patients undergoing elective LS had an underlying hematological disorder. CONCLUSIONS By analyzing the NSQIP-P database, we evaluated the largest cohort of pediatric patients undergoing elective LS to date. We identified a higher incidence of VTE following this procedure relative to the rate of VTE in the overall population in the NSQIP-P database, as well as those undergoing elective laparoscopic abdominopelvic operations. The relatively higher incidence of VTE after elective LS is likely due to the presence of underlying hematological conditions. Given the low incidence of complications associated with pharmacologic VTE prophylaxis, the results of this study suggest that further research is warranted to establish the efficacy of perioperative pharmacological VTE prophylaxis in pediatric patients undergoing elective LS.

Abstract
OBJECTIVES Quality and safety improvement are global priorities. In the last two decades, the United States has introduced several payment reforms to improve patient safety. The Agency for Healthcare Research and Quality (AHRQ) developed tools to identify preventable inpatient adverse events using administrative data, patient safety indicators (PSIs). The aim of this study was to assess changes in national patient safety trends that corresponded to U.S. pay-for-performance reforms. METHODS This is a retrospective, longitudinal analysis to estimate temporal changes in 13 AHRQ's PSIs. National inpatient sample from the AHRQ and estimates were weighted to represent a national sample. We analyzed PSI trends, Center for Medicaid and Medicare Services payment policy changes, and Inpatient Prospective Payment System regulations and notices between 2000 and 2013. RESULTS Of the 13 PSIs studied, 10 had an overall decrease in rates and 3 had an increase. Joinpoint analysis showed that 12 of 13 PSIs had decreasing or stable trends in the last 5 years of the study. Central-line blood stream infections had the greatest annual decrease (-31.1 annual percent change between 2006 and 2013), whereas postoperative respiratory failure had the smallest decrease (-3.5 annual percent change between 2005 and 2013). With the exception of postoperative hip fracture, significant decreases in trends preceded federal payment reform initiatives. CONCLUSIONS National in-hospital patient safety has significantly improved between 2000 and 2015, as measured by PSIs. In this study, improvements in PSI trends often proceeded policies targeting patient safety events, suggesting that intense public discourses targeting patient safety may drive national policy reforms and that these improved trends may be sustained by the Center for Medicare and Medicaid Services policies that followed.

Venous Thromboembolism in Cancer Patients on Simultaneous and Palliative Care. Cancers (Basel) 2020; 12:cancers12051167.

Abstract
Simultaneous care represents the ideal integration between early supportive and palliative care in cancer patients under active antineoplastic treatment. Cancer patients require a composite clinical, social and psychological management that can be effective only if care continuity from hospital to home is guaranteed and if such a care takes place early in the course of the disease, combining standard oncology care and palliative care. In these settings, venous thromboembolism (VTE) represents a difficult medical challenge, for the requirement of acute treatments and for the strong impact on anticancer therapies that might be delayed or, even, totally discontinued. Moreover, cancer patients not only display high rates of VTE occurrence/recurrence but are also more prone to bleeding and this forces clinicians to optimize treatment strategies, balancing between hemorrhages and thrombus formation. VTE prevention is, therefore, regarded as a double-edged sword. Indeed, while on one hand the appropriate use of antithrombotic agents can reduce VTE occurrence, on the other it significantly increases the bleeding risk, especially in the frail patients who present with multiple co-morbidities and poly-therapy that can interact with anticoagulant drugs. For these reasons, thromboprophylaxis should start while active cancer treatment is ongoing, according to a simultaneous care model in a patient-centered perspective.

Abstract
BACKGROUND The prevalence of deep venous thrombosis in patients with advanced cancer is unconfirmed and it is unknown whether current international thromboprophylaxis guidance is applicable to this population. We aimed to determine prevalence and predictors of femoral deep vein thrombosis in patients admitted to specialist palliative care units (SPCUs). METHODS We did this prospective longitudinal observational study in five SPCUs in England, Wales, and Northern Ireland (four hospices and one palliative care unit). Consecutive adults with cancer underwent bilateral femoral vein ultrasonography on admission and weekly until death or discharge for a maximum of 3 weeks. Data were collected on performance status, attributable symptoms, and variables known to be associated with venous thromboembolism. Patients with a short estimated prognosis (<5 days) were ineligible. The primary endpoint of the study was the prevalence of femoral deep vein thrombosis within 48 h of SPCU admission, analysed by intention to treat. This study is registered with the ISRCTN registry, number ISRCTN97567719. FINDINGS Between June 20, 2016, and Oct 16, 2017, 343 participants were enrolled (mean age 68·2 years [SD 12·8; range 25-102]; 179 [52%] male; mean Australian-modified Karnofsky performance status 49 [SD 16·6; range 20-90]). Of 273 patients with evaluable scans, 92 (34%, 95% CI 28-40) had femoral deep vein thrombosis. Four participants with a scan showing no deep vein thrombosis on admission developed a deep vein thrombosis on repeat scanning over 21 days. Previous venous thromboembolism (p=0·014), being bedbound in the past 12 weeks for any reason (p=0·003), and lower limb oedema (p=0·009) independently predicted deep vein thrombosis. Serum albumin concentration (p=0·43), thromboprophylaxis (p=0·17), and survival (p=0·45) were unrelated to deep vein thrombosis. INTERPRETATION About a third of patients with advanced cancer admitted to SPCUs had a femoral deep vein thrombosis. Deep vein thrombosis was not associated with thromboprophylaxis, survival, or symptoms other than leg oedema. These findings are consistent with venous thromboembolism being a manifestation of advanced disease rather than a cause of premature death. Thromboprophylaxis for SPCU inpatients with poor performance status seems to be of little benefit. FUNDING National Institute for Health Research (Research for Patient Benefit programme).

Abstract
BACKGROUND Venous thromboembolism (VTE) is a leading cause of morbidity and mortality in hospitalized patients. While numerous randomized controlled trials (RCTs) have shown that the appropriate use of thromboprophylaxis in hospitalized patients at risk for VTE is safe, effective, and cost-effective, thromboprophylaxis remains underused or inappropriately used. Our previous review suggested that system-wide interventions, such as education, alerts, and multifaceted interventions were more effective at improving the prescribing of thromboprophylaxis than relying on individual providers' behaviors. However, 47 of the 55 included studies in our previous review were observational in design. Thus, an update to our systematic review, focused on the higher level of evidence of RCTs only, was warranted. OBJECTIVES To assess the effects of system-wide interventions designed to increase the implementation of thromboprophylaxis and decrease the incidence of VTE in hospitalized adult medical and surgical patients at risk for VTE, focusing on RCTs only. SEARCH METHODS Our research librarian conducted a systematic literature search of MEDLINE Ovid, and subsequently translated it to CENTRAL, PubMed, Embase Ovid, BIOSIS Previews Ovid, CINAHL, Web of Science, the Database of Abstracts of Reviews of Effects (DARE; in the Cochrane Library), NHS Economic Evaluation Database (EED; in the Cochrane Library), LILACS, and clinicaltrials.gov from inception to 7 January 2017. We also screened reference lists of relevant review articles. We identified 12,920 potentially relevant records. SELECTION CRITERIA We included all types of RCTs, with random or quasi-random methods of allocation of interventions, which either randomized individuals (e.g. parallel group, cross-over, or factorial design RCTs), or groups of individuals (cluster RCTs (CRTs)), which aimed to increase the use of prophylaxis or appropriate prophylaxis, or decrease the occurrence of VTE in hospitalized adult patients. We excluded observational studies, studies in which the intervention was simply distribution of published guidelines, and studies whose interventions were not clearly described. Studies could be in any language. DATA COLLECTION AND ANALYSIS We collected data on the following outcomes: the number of participants who received prophylaxis or appropriate prophylaxis (as defined by study authors), the occurrence of any VTE (symptomatic or asymptomatic), mortality, and safety outcomes, such as bleeding. We categorized the interventions into alerts (computer or human alerts), multifaceted interventions (combination of interventions that could include an alert component), educational interventions (e.g. grand rounds, courses), and preprinted orders (written predefined orders completed by the physician on paper or electronically). We meta-analyzed data across RCTs using a random-effects model. For CRTs, we pooled effect estimates (risk difference (RD) and risk ratio (RR), with 95% confidence interval (CI), adjusted for clustering, when possible. We pooled results if three or more trials were available for a particular intervention. We assessed the certainty of the evidence according to the GRADE approach. MAIN RESULTS From the 12,920 records identified by our search, we included 13 RCTs (N = 35,997 participants) in our qualitative analysis and 11 RCTs (N = 33,207 participants) in our meta-analyses. PRIMARY OUTCOME Alerts were associated with an increase in the proportion of participants who received prophylaxis (RD 21%, 95% CI 15% to 27%; three studies; 5057 participants; I² = 75%; low-certainty evidence). The substantial statistical heterogeneity may be in part explained by patient types, type of hospital, and type of alert. Subgroup analyses were not feasible due to the small number of studies included in the meta-analysis.Multifaceted interventions were associated with a small increase in the proportion of participants who received prophylaxis (cluster-adjusted RD 4%, 95% CI 2% to 6%; five studies; 9198 participants; I² = 0%; moderate-certainty evidence). Multifaceted interventions with an alert component were found to be more effective than multifaceted interventions that did not include an alert, although there were not enough studies to conduct a pooled analysis. SECONDARY OUTCOMES Alerts were associated with an increase in the proportion of participants who received appropriate prophylaxis (RD 16%, 95% CI 12% to 20%; three studies; 1820 participants; I² = 0; moderate-certainty evidence). Alerts were also associated with a reduction in the rate of symptomatic VTE at three months (RR 64%, 95% CI 47% to 86%; three studies; 5353 participants; I² = 15%; low-certainty evidence). Computer alerts were associated with a reduction in the rate of symptomatic VTE, although there were not enough studies to pool computer alerts and human alerts results separately. AUTHORS' CONCLUSIONS We reviewed RCTs that implemented a variety of system-wide strategies aimed at improving thromboprophylaxis in hospitalized patients. We found increased prescription of prophylaxis associated with alerts and multifaceted interventions, and increased prescription of appropriate prophylaxis associated with alerts. While multifaceted interventions were found to be less effective than alerts, a multifaceted intervention with an alert was more effective than one without an alert. Alerts, particularly computer alerts, were associated with a reduction in symptomatic VTE at three months, although there were not enough studies to pool computer alerts and human alerts results separately.Our analysis was underpowered to assess the effect on mortality and safety outcomes, such as bleeding.The incomplete reporting of relevant study design features did not allow complete assessment of the certainty of the evidence. However, the certainty of the evidence for improvement in outcomes was judged to be better than for our previous review (low- to moderate-certainty evidence, compared to very low-certainty evidence for most outcomes). The results of our updated review will help physicians, hospital administrators, and policy makers make practical decisions about adopting specific system-wide measures to improve prescription of thromboprophylaxis, and ultimately prevent VTE in hospitalized patients.

Abstract
SummaryIt was the aim of this review to assess the incidence of venous thromboembolism (VTE) and current practice patterns for VTE prophylaxis among medical patients with acute illness in Europe. A literature search was conducted on the epidemiology and prophylaxis practices of VTE prevention among adult patients treated in-hospital for major medical conditions. A total of 21 studies with European information published between 1999 and April 2010 were retrieved. Among patients hospitalised for an acute medical illness, the incidence of VTE varied between 3.65% (symptomatic only over 10.9 days) and 14.9% (asymptomatic and symptomatic over 14 days). While clinical guidelines recommend pharmacologic VTE prophylaxis for patients admitted to hospital with an acute medical illness who are bedridden, clear identification of specific risk groups who would benefit from VTE prophylaxis is lacking. In the majority of studies retrieved, prophylaxis was under-used among medical inpatients; 21% to 62% of all patients admitted to the hospital for acute medical illnesses did not receive VTE prophylaxis. Furthermore, among patients who did receive prophylaxis, a considerable proportion received medication that was not in accord with guidelines due to short duration, suboptimal dose, or inappropriate type of prophylaxis. In most cases, the duration of VTE prophylaxis did not exceed hospital stay, the mean duration of which varied between 5 and 11 days. In conclusion, despite demonstrated efficacy and established guidelines supporting VTE prophylaxis, utilisation rates and treatment duration remain suboptimal, leaving medical patients at continued risk for VTE. Improved guideline adherence and effective care delivery among the medically ill are stressed.

Abstract
Deep vein thrombosis (DVT) is a prevalent problem for orthopedic patients, particularly owing to the nature of operative interventions and treatment procedures, predisposing to an high risk of DVT. This descriptive study was conducted to determine the levels of risk, the risk factors, and their odds ratio for DVT in patients undergoing major orthopedic surgery. Data were collected using a Patient Information Form and the Autar DVT Risk Assessment Scale (DVTRAS) in orthopedic wards of a university hospital on postoperative day 2. Data were analyzed using descriptive, comparative analysis, and binary logistic regression. The 102 patients (mean age, 52.58 ± 21.58 years) were hospitalized for a mean of 14.35 ± 14.56. Of the sample, 53.9% were female, 65.7% had a history of previous surgery, and 54.9% had undergone total hip/knee arthroplastic surgery, 67.6% of patients wore graduated compression stockings, and 62.7% were administered liquid infusion. Those patients had moderate risk score (12.77 ± 5.66) in the Autar DVTRAS. According to binary logistic regression analysis, aging, obesity, immobility, and acute and chronic diseases were significant risk factors for postoperative DVT (p ≤ .05). This study highlights evidence on the degree of DVT risk, risk factors, and impact of venous thromboembolism in patients undergoing major orthopedic operations. For evidence-based clinical practice, these high-level risk factors should be taken into account in the prevention of DVT in orthopedic patients.

Abstract
Low-molecular-weight heparins (LMWHs) endure as important drugs for thromboprophylaxis. Although clinical use relies on the subcutaneous (SC) route, our previous studies show that single-dose orally administered LMWHs have antithrombotic activity. Since thromboprophylaxis requires long-term treatment, we examined antithrombotic effects of subacute oral LMWHs in a rat venous thrombosis model and compared results to SC or single-dose oral administration. We measured LMWH in endothelium and plasma, weight change and complete blood counts (CBC). Oral LMWH tinzaparin (3 × 0.1 mg/kg/12 or 24 hours) or reviparin (3 × 0.025 mg/kg/24 hours) significantly decreased thrombosis compared to saline. In the subacute study (60 × 0.1 mg/kg/12 hours), oral or SC tinzaparin significantly reduced thrombosis compared to saline but not to single or 3 × 0.1 mg/kg/12 hours oral tinzaparin. Antithrombotic effects were similar between oral and SC administration. LMWH was found on endothelium following oral but not SC administration. Endothelial concentrations were significantly correlated with incidence of stable thrombi ( P = 0.021 and 0.04 for aortic and vena cava endothelium respectively, χ2 test) and total thrombi ( P = 0.003 for vena cava endothelium). Anti-Xa activity was significantly greater for oral or SC LMWH than saline and significantly greater for SC versus oral LMWH. Values for CBCs were within normal ranges (mean ± 2 SD). There was no evidence of bleeding. Weight gain was similar between groups. In conclusion, subacute oral and SC LMWH have similar antithrombotic effects. Antithrombotic activity with oral administration is correlated with endothelial LMWH concentrations but not with plasma anticoagulant activity.

The Effectiveness of a Risk Stratification Protocol for Thromboembolism Prophylaxis After Hip and Knee Arthroplasty. J Arthroplasty 2016; 31:1299-1306. [PMID: 26777547 DOI: 10.1016/j.arth.2015.12.007] [Citation(s) in RCA: 34] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/28/2015] [Revised: 12/01/2015] [Accepted: 12/03/2015] [Indexed: 02/01/2023] Open
Abstract
BACKGROUND This study's purpose was to present our institution's experience with the use of a risk stratification protocol for venous thromboembolism (VTE) prophylaxis in joint arthroplasty in which "routine" risk patients receive a mobile compression device in conjunction with aspirin and "high"-risk patients receive warfarin for thromboprophylaxis. METHODS This was a prospective study of patients undergoing primary or revision knee or hip arthroplasty. Exclusion criteria were patients with a current deep vein thrombosis, history of pulmonary embolism, chronic warfarin therapy, planned multiple surgeries, and prolonged postoperative immobilization. Patients were stratified as either routine or high risk. Routine risk patients received mobile compression devices for 10 days and aspirin twice daily for 6 weeks, whereas high-risk patients received warfarin for 4 weeks and compression stockings for 6 weeks. RESULTS A total of 3143 total joint arthroplasties were enrolled (2222, 70.7% "routine"; 921, 29.3% "high risk"). The rate of symptomatic VTE within 6 weeks postoperatively was 0.7% (95% CI 0.3%-1.0%) in the standard vs 0.5% (95% CI 0.01%-1.0%) in the high-risk cohort (P = .67), and within 6 months postoperatively was 0.6% (95% CI 0.3%-1.0%) in the standard vs 1.1% (95% CI 0.4%-1.8%) in the high-risk cohort (P = .23). The rate of major bleeding events was significantly lower in the routine (0.4%; 95% CI 0.1%-0.6%) vs high-risk (2.0%; 95% CI 1.0%-3.0%; P < .001) cohort. CONCLUSIONS This study demonstrates that use of a risk stratification protocol allowed the avoidance of more aggressive anticoagulation in 70% of patients while achieving a low overall incidence of symptomatic VTE.

Abstract
Ideally, thrombophilia testing should be tailored to the type of thrombotic event without the influence of anticoagulation therapy or acute phase effects which can give false positive results that may result in long term anticoagulation. However, thrombophilia testing is often performed routinely in unselected patients. We analyzed all consecutive thrombophilia testing orders during the months of October and November 2009 at an academic teaching institution. Information was extracted from electronic medical records for the following: indication, timing, comprehensiveness of tests, anticoagulation therapy at the time of testing, and confirmatory repeat testing, if any. Based on the findings of this analysis, we established local guidelines in May 2013 for appropriate thrombophilia testing, primarily to prevent testing during the acute thrombotic event or while the patient is on anticoagulation. We then evaluated ordering practices 22 months after guideline implementation. One hundred seventy-three patients were included in the study. Only 34% (58/173) had appropriate indications (unprovoked venous or arterial thrombosis or pregnancy losses). 51% (61/119) with an index clinical event were tested within one week of the event. Although 46% (79/173) were found to have abnormal results, only 46% of these had the abnormal tests repeated for confirmation with 54% potentially carrying a wrong diagnosis with long term anticoagulation. Twenty-two months after guideline implementation, there was an 84% reduction in ordered tests. Thus, this study revealed that a significant proportion of thrombophilia testing was inappropriately performed. We implemented local guidelines for thrombophilia testing for clinicians, resulting in a reduction in healthcare costs and improved patient care.

Abstract
A light to moderate consumption of certain types of alcoholic beverages may exert a favorable effect on cardiovascular risk, but no conclusive information is available on the putative relationship between alcohol intake and the risk of venous thromboembolism (VTE). We performed an electronic search on Medline and Scopus, using the keywords "venous thromboembolism", "venous thrombosis" and "alcohol", to identify clinical studies linking alcohol intake and VTE risk. The literature search generated 16 studies, 4 of which are case-control, 1 cross-sectional and 11 prospective. Significant reduction of VTE associated with alcohol intake is observed in only 4/16 studies, and in all these the association is only meaningful for a moderate amount of alcohol (i.e., 2-4 glasses). Unlike these trials, two other studies observe that alcohol intake is associated with an increased risk of VTE, whereas the association is insignificant in the remainder. Binge drinking increases the VTE risk in one study but not in another. The consumption of beer is associated with a decreased VTE risk in one study but not in two others. We hence conclude that the relationship between intake of alcoholic beverages and increased or decreased risk of VTE is largely elusive.

Abstract
This study's purpose was to present the use of a risk stratification protocol in which "routine" risk patients receive a mobile compression device with aspirin and "high" risk patients receive warfarin for thromboprophylaxis after hip arthroplasty. 1859 hip arthroplasty patients were prospectively enrolled (1402 routine risk--75.4%, 457 high risk--24.6%). The cumulative rate of venous thromboembolism events was 0.5% in the routine versus 0.5% in the high-risk cohort within 6weeks postoperatively (P=1.00). Patients in the routine risk cohort had a lower rate of major bleeding (0.5% versus 2.0%, P=0.006) and wound complications (0.2% versus 1.2%, P=0.01). Use of our risk stratification protocol allowed the avoidance of more aggressive anticoagulation in 75% of patients while achieving a low overall incidence of symptomatic VTE.

Abstract
IMPORTANCE Venous thromboembolism (VTE) is an important complication of colorectal surgery, but its incidence is unclear in the era of VTE prophylaxis. OBJECTIVE To describe the incidence of and risk factors associated with thromboembolic complications and contemporary VTE prophylaxis patterns following colorectal surgery. DESIGN, SETTING, AND PARTICIPANTS Prospective data from the Washington State Surgical Care and Outcomes Assessment Program (SCOAP) linked to a statewide hospital discharge database. At 52 Washington State SCOAP hospitals, participants included consecutive patients undergoing colorectal surgery between January 1, 2006, and December 31, 2011. MAIN OUTCOMES AND MEASURES Venous thromboembolism complications in-hospital and up to 90 days after surgery. RESULTS Among 16,120 patients (mean age, 61.4 years; 54.5% female), the use of perioperative and in-hospital VTE chemoprophylaxis increased significantly from 31.6% to 86.4% and from 59.6% to 91.4%, respectively, by 2011 (P < .001 for trend for both). Overall, 10.6% (1399 of 13,230) were discharged on a chemoprophylaxis regimen. The incidence of VTE was 2.2% (360 of 16,120). Patients undergoing abdominal operations had higher rates of 90-day VTE compared with patients having pelvic operations (2.5% [246 of 9702] vs 1.8% [114 of 6413], P = .001). Those having an operation for cancer had a similar incidence of 90-day VTE compared with those having an operation for nonmalignant processes (2.1% [128 of 6213] vs 2.3% [232 of 9902], P = .24). On adjusted analysis, older age, nonelective surgery, history of VTE, and operations for inflammatory disease were associated with increased risk of 90-day VTE (P < .05 for all). There was no significant decrease in VTE over time. CONCLUSIONS AND RELEVANCE Venous thromboembolism rates are low and largely unchanged despite increases in perioperative and postoperative prophylaxis. These data should be considered in developing future guidelines.

Abstract
Venous thromboembolism (VTE) prevention is an international patient safety issue. The author has observed gaps in prescription and provision of VTE prophylaxis, and that the attitude to VTE is often reactive rather than proactive. This concept analysis aims to explore proactivity and apply it to VTE prevention to address this. Ten databases were searched (1992-2012) using the keywords proactive, proactivity, nurse, nursing, VTE/venous thromboembolism, prevent/prevention/preventing, behaviour, DVT/PE (deep vein thrombosis, pulmonary embolism). The Walker and Avant (2010) method of concept analysis identified the defining attributes as personal initiative, taking charge and feedback-seeking behaviour. Antecedents and consequences have been identified, and empirical referents are demonstrated. Defining proactivity in VTE prevention has the potential to increase prescription and, crucially, provision of prophylaxis, thereby improving patient care, reducing avoidable harm and improving the patient experience.

Abstract
Recently, Levy et al questioned the effectiveness of mobile compression devices (MCDs) as the sole method of thromboprophylaxis following simultaneous bilateral total knee arthroplasty (TKA). This study's purpose was to assess if the addition of aspirin to MCDs improves venous thromboembolism (VTE) prevention following simultaneous bilateral TKA. Ninety-six patients (192 TKAs) were retrospectively reviewed: 47 patients received MCDs for 10 days and aspirin for 6 weeks postoperatively based on a risk stratification protocol, while 49 patients received warfarin for 4 weeks postoperatively. One symptomatic VTE was noted in the warfarin cohort, while one patient in the MCD/aspirin cohort and three patients in the warfarin cohort were readmitted within 3 months of surgery. In appropriately selected patients, MCDs with aspirin shows promise in VTE prevention following simultaneous bilateral TKA.

Abstract
Patient education about venous thromboembolism (VTE) prevention is needed to prevent complications and costly re-hospitalization. Nurses are uniquely positioned to provide vital education as patients transition from the inpatient setting to after discharge. Still, little is known about patient knowledge deficits and those of their caregivers. The purpose of this study was to explore VTE prevention knowledge in a sample of older hip fracture patients and family caregivers. At the time of hospital discharge, surveys were completed by hip fracture surgery patients (≥65; n=30) and family caregivers (n=30). Participants reported needs for more prophylactic anticoagulation and side effects education. Mean education satisfaction was 3.49 out of 5 among patients and 3.83 among caregivers. Focused patient education regarding the wisdom of VTE prevention, potential risks involved, and patient and caregiver roles in advocating for better prevention measures is needed for these patients at risk for hospital readmission secondary to VTE.

Abstract
BACKGROUND: Didactic lectures are frequently used to improve compliance with practice guidelines. This study assessed the knowledge of health-care providers (HCPs) at a tertiary-care hospital of its evidence-based thromboprophylaxis guidelines and the impact of didactic lectures on their knowledge. METHODS: The hospital launched a multifaceted approach to improve thromboprophylaxis practices, which included posters, a pocket-size guidelines summary and didactic lectures during the annual thromboprophylaxis awareness days. A self-administered questionnaire was distributed to HCPs before and after lectures on thromboprophylaxis guidelines (June 2010). The questionnaire, formulated and validated by two physicians, two nurses and a clinical pharmacist, covered various subjects such as risk stratification, anticoagulant dosing and the choice of anticoagulants in specific clinical situations. RESULTS: Seventy-two and 63 HCPs submitted the pre- and post-test, respectively (62% physicians, 28% nurses, from different clinical disciplines). The mean scores were 7.8 ± 2.1 (median = 8.0, range = 2-12, maximum possible score = 15) for the pre-test and 8.4 ± 1.8 for the post-test, P = 0.053. There was no significant difference in the pre-test scores of nurses and physicians (7.9 ± 1.7 and 8.2 ± 2.4, respectively, P = 0.67). For the 35 HCPs who completed the pre- and post-tests, their scores were 7.7 ± 1.7 and 8.8 ± 1.6, respectively, P = 0.003. Knowledge of appropriate anticoagulant administration in specific clinical situations was frequently inadequate, with approximately two-thirds of participants failing to adjust low-molecular-weight heparin doses in patients with renal failure. CONCLUSIONS: Education via didactic lectures resulted in a modest improvement of HCPs′ knowledge of thromboprophylaxis guidelines. This supports the need for a multifaceted approach to improve the awareness and implementation of thromboprophylaxis guidelines.

Abstract
This paper focuses on financial incentives rewarding successful implementation of guidelines in the UK National Health Service (NHS). In particular, it assesses the implementation of National Institute for Health and Clinical Excellence (NICE) venous thrombo-embolism (VTE) guidance in 2010 on the risk assessment and secondary prevention of VTE in hospital in-patients and the financial incentives driving successful implementation introduced by the Commissioning for Quality and Innovation for Payment Framework (CQUIN) for 2010-2011. We systematically compared the implementation of evidence-based national guidance on VTE prevention across two specialities (general medicine and orthopaedics) in four hospital sites in the greater South West of England by auditing and evaluating VTE prevention activity for 2009 (i.e. before the 2010 NICE guideline) and late 2010 (almost a year after the guideline was published). Analysis of VTE prevention activity reported in 816 randomly selected orthopaedic and general medical in-patient medical records was complemented by a qualitative study into the practical responses to revised national guidance. This paper's contribution to knowledge is to suggest that by financially rewarding the implementation of national guidance on VTE prevention, paradoxes and contradictions have become apparent between the 'payment by volume system' of Healthcare Resource Groups and the 'payment by results' system of CQUIN.

Abstract
A debate concerns the utility of large screening for acquired or inherited thrombophilia. The study concerns relationship between inherited thrombophilic status and lower limb deep vein thrombosis (LDVT) and highlights the possible use of extensive thrombophilia screening to determine an emerging risk of LDVT. From January 2010 to January 2012, 103 consecutive patients with LDVT were considered. In all, 57 (55.3%) patients with LDVT showed inherited thrombophilia. The most frequent trombophilic alterations were deficiency of protein S (33 patients, 32.0%), methylentethrafolate reductase (MTHFR) gene C677T variant (22 patients, 21.4%), protrombin gene G20210A alteration (50, 14.6%), and deficiency of protein C (12, 11.6%). Age and MTHFR variant were found related to LDVT and thrombophilia was related to distal LDVT. A high frequency of thrombophylic factor was found in patients with LDVT, but we believe that a generic genetic screening should not be suggested for these patients.

Abstract
BACKGROUND Colectomy patients are at high-risk for venous thromboembolism (VTE), but associated risk factors and best prophylaxis in this defined population are only generalized. METHODS Fifteen hospitals prospectively collected pre-, peri-, and postoperative variables related to VTE and prophylaxis, in addition to the variables defined by the National Surgical Quality Improvement Program between 2008 and 2009 concerning open and laparoscopic colectomy patients with 30-day outcomes. Symptomatic VTE was the primary outcome, and risk factors were tested for association with VTE using multiple logistic regression. RESULTS The cohort included 3,464 patients with a mean age of 65; 53% were female. Overall, the 30d incidence of VTE was 2.2%. VTE prophylaxis included sequential compression devices (SCDs, 11%) alone; pharmacologic prophylaxis alone (15%); and both SCDs and pharmacologic prophylaxis (combined prophylaxis, 74%). VTE was associated with each additional year of age (OR, 1.05; 95% CI 1.02-1.06, P < .001); increased body mass index (OR 1.03; CI 1.01-1.05; P = .02); preoperative anemia (OR 2.4; CI 1.2-4.8; P = .011); contaminated wound (OR 3.4; CI 1.6-7.3; P < .01); postoperative surgical site infection (OR 2.5; CI 1.2-5.2; P < .011); and postoperative sepsis/pneumonia (OR 3.6;CI 1.9-6.7; P < .01). Postoperative factors alone accounted for 32% of VTE risk. When controlling for all other factors, only combination prophylaxis was protective against VTE (OR 0.48; CI 0.27-0.9; P = .02). Operative time, presence of disseminated malignancy, anastomotic leak, transfusion, urinary tract infection, and laparoscopic procedure were not significantly associated with VTE. Propensity matching showed that unfractionated heparin was equivalent to low molecular weight heparin, and the transfusion rate was not increased with pharmacologic prophylaxis compared to SCDs alone. CONCLUSION Regardless of preoperative factors, VTE prophylaxis using a combination of SCDs and chemoprophylaxis was associated with significant reduction in VTE and should be standard care for patients after colectomy.

Abstract
Each year in Australia, about 1 in 1000 people develop a first episode of venous thromboembolism (VTE), which approximates to about 20,000 cases. More than half of these episodes occur during or soon after a hospital admission, which makes them potentially preventable. This paper summarises recommendations from the National Health and Medical Research Council's 'Clinical Practice Guideline for the Prevention of Venous Thromboembolism in Patients Admitted to Australian Hospitals' and describes the way these recommendations were developed. The guideline has two aims: to provide advice on VTE prevention to Australian clinicians and to support implementation of effective programmes for VTE prevention in Australian hospitals by offering evidence-based recommendations which local hospital guidelines can be based on. Methods for preventing VTE are pharmacological and/or mechanical, and they require appropriate timing, dosing and duration and also need to be accompanied by good clinical care, such as promoting mobility and hydration whilst in hospital. With some procedures or injuries, the risk of VTE is sufficiently high to require that all patients receive an effective form of prophylaxis unless this is contraindicated; in other clinical settings, the need for prophylaxis requires individual assessment. For optimal VTE prevention, all patients admitted to hospital should have early and formal assessments of: (i) their intrinsic VTE risk and the risks related to their medical conditions; (ii) the added VTE risks resulting from surgery or trauma; (iii) bleeding risks that would contraindicate pharmacological prophylaxis; (iv) any contraindications to mechanical prophylaxis, culminating in (v) a decision about prophylaxis (pharmacological and/or mechanical, or none). The most appropriate form of prophylaxis will depend on the type of surgery, medical condition and patient characteristics. Recommendations for various clinical circumstances are provided as summary tables with relevance to orthopaedic surgical procedures, other types of surgery and medical inpatients. In addition, the tables indicate the grades of supporting evidence for the recommendations (these range from Grade A which can be trusted to guide practice, to Grade D where there is more uncertainty; Good Practice Points are consensus-based expert opinions).

Abstract
BACKGROUND Deep vein thrombosis and pulmonary embolism (PE) are responsible for substantial mortality, morbidity, and impaired health-related quality of life. The aim of this study was to evaluate the correlates of in-hospital deaths among hospitalizations with a diagnosis of PE in the United States. METHODS By using data from the 2001-2008 National Hospital Discharge Survey, we assessed the correlates of in-hospital deaths among 14,721 hospitalizations with a diagnosis of PE and among subgroups stratified by age, sex, race, days of hospital stay, type of admission, cancer, pneumonia, and fractures. We produced adjusted rate ratios (aRR) and 95% confidence intervals using log-linear multivariate regression models. RESULTS Regardless of the listing position of diagnostic codes, we observed an increased likelihood of in-hospital death in subgroups of hospitalizations with ages 50 years and older (aRR = 1.82-8.48), less than 7 days of hospital stay (aRR = 1.43-1.57), cancer (aRR = 2.10-2.28), pneumonia (aRR = 1.79-2.20), or fractures (aRR = 2.18) (except for first-listed PE), when compared to the reference groups with ages 1-49 years, 7 days or more of hospital stay, without cancer, pneumonia, or fractures while adjusting for covariates. In addition, we observed an increased likelihood of in-hospital death for first-listed PE in hospitalizations of women, when compared to those of men (aRR = 1.45). CONCLUSIONS The results of this study provide support for identifying, developing, and implementing effective, evidence-based clinical assessment and management strategies to reduce PE-related morbidity and mortality among hospitalized PE patients who may have concurrent health conditions including cancer, pneumonia, and fractures.

Abstract
BACKGROUND Pelvic and acetabular fractures have been known as one of the high risk factors for developing deep vein thrombosis (DVT), but thromboprophylaxis for patients with such fractures remains underused despite its widely accepted benefits. Current guidelines have not been universally adopted in clinical practice. The purpose of this study is to introduce a Thrombotic Risk Assessment Questionary (assessment table) according to evidence-based guidelines and evaluate its impact on the use of thromboprophylaxis for patients with pelvic and acetabular fractures. MATERIALS AND METHODS We retrospectively reviewed 305 consecutive patients with pelvic and acetabular fractures from August 1, 2008 through September 30, 2010. The control group without using the assessment table included 153 patients admitted during the first 13 months, and the assessment group using the assessment table included 152 patients admitted during the following months. Data on clinical outcomes of DVT, the number of patients receiving prophylaxis, and the time of the first dose of anticoagulant were collected. RESULTS Compared with the control group, Patients using the assessment table were more likely to be given DVT prophylaxis (84.2% vs. 37.3%, P < 0.05) and the time of the first dose of anticoagulant was reduced (4.32 days ± 4.78 days vs. 6.6 days ± 5.96 days, P < 0.05). Patients in the assessment group had lower risk of developing DVT (8.6% vs. 20.3%, P < 0.05). CONCLUSION The assessment table can significantly improve the use of thromboprophylaxis after pelvic and acetabular fractures, which will likely reduce the incidence of DVT. Developing individual hospital prophylaxis strategy is an effective way to determine whether hospitalized patients should receive pharmacologic and/or mechanical prophylaxis or not.

Abstract
INTRODUCTION Hemostasis in women is affected by changes of estrogen levels. The role of endogenous estrogens on risk of venous thromboembolism (VTE) remains unclear. The aim of this study was to investigate the importance of acquired and genetic risk factors for VTE in pre-and postmenopausal women. METHOD In a nationwide case-control study we included as cases 1470 women, 18 to 64years of age with a first time VTE. The 1590 controls were randomly selected and matched by age to the cases. Information on risk factors was obtained by interviews and DNA-analyses. We used unconditional logistic regression to calculate odds ratios (ORs) with 95% confidence intervals (CIs). RESULTS The ORs were generally of similar magnitude in pre- and postmenopausal women. The highest risk was for the combination of surgery and cast (adjusted OR 54.12, 95% CI 16.62-176.19) in postmenopausal women. The adjusted OR for use of menopausal hormone therapy was 3.73 (95% CI 1.86-7.50) in premenopausal and 2.22 (95% CI 1.54-3.19) in postmenopausal women. Overweight was linked to an increased risk and exercise to a decreased risk, regardless of menopausal status. CONCLUSION Menopausal status had only minor influence on the risk levels. Acquired transient risk factors conveyed the highest risks for VTE.

Enoxaparin versus tinzaparin for venous thromboembolic prophylaxis during rehabilitation after acute spinal cord injury: a retrospective cohort study comparing safety and efficacy. PM R 2012; 4:11-7.

Abstract
OBJECTIVE To compare the safety and efficacy of 3 low-molecular-weight heparin (LMWH) treatments (enoxaparin, 40 mg once daily, with an alternative LMWH, tinzaparin, 3500 or 4500 units once daily) for the prevention of venous thromboembolic events (VTEs) after acute spinal cord injury (SCI). DESIGN Retrospective, chart review study. SETTING Acute inpatient rehabilitation facility. PARTICIPANTS Patients admitted to acute rehabilitation within 3 months of either a traumatic or nontraumatic SCI during a 15-month time frame and who received either enoxaparin or tinzaparin for VTE prophylaxis. MAIN OUTCOME MEASURES Symptomatic VTE incidence and bleeding events during acute rehabilitation. RESULTS A total of 140 participants who met inclusion criteria were admitted at a median of 15 days after an acute SCI. Before admission to rehabilitation, 23.6% were not on any VTE prophylaxis, 55.7% were on enoxaparin, 17.1% were on unfractionated heparin, 1.4% were on treatment doses of a LMWH, and 2.1% did not have documentation available regarding type of prophylaxis before admission. No patients were receiving tinzaparin before admission. During rehabilitation, 68 participants received prophylaxis with enoxaparin, whereas 14 and 58 participants received tinzaparin 3500 or 4500 units, respectively. Symptomatic VTE developed in 14 patients during rehabilitation, including 4 developing pulmonary emboli. Compared with patients receiving tinzaparin 3500 units, both those receiving enoxaparin had significantly reduced odds of VTE (odds ratio [OR] 0.12; 95% confidence interval [95% CI] 0.02-0.65)] and those receiving tinzaparin 4500 units had significantly reduced odds of VTE (OR 0.18; 95% CI 0.03-0.93). After we adjusted for age, previous pharmacologic prophylaxis, and etiology for the SCI (traumatic vs nontraumatic) via propensity scores, pharmacologic prophylaxis with enoxaparin remained protective for VTE compared with tinzaparin 3500 units (adjusted OR 0.15; 95% CI 0.02-0.93). The use of prophylaxis before admission with enoxaparin compared with no prophylaxis was associated with decreased risk of VTE during rehabilitation (adjusted OR 0.20; 95% CI 0.04-0.88); however, this association was no longer significant when we adjusted for prophylaxis during rehabilitation. The etiology for the SCI and the presence of an inferior vena cava filter were not associated with VTE. One patient receiving enoxaparin required transfer for a bleeding event, and no patients had greater than a 1-g decrease in hemoglobin during the rehabilitation stay. CONCLUSIONS VTE was more prevalent in participants receiving tinzaparin 3500 units than in participants who received tinzaparin 4500 units or enoxaparin. Bleeding events were low with the use of LMWH for prophylaxis during acute rehabilitation. Although the use of prophylaxis before rehabilitation may be protective of VTE events, after we adjusted for VTE prophylaxis during rehabilitation, type of previous prophylaxis was not found to be significantly protective of VTE events during rehabilitation.

Abstract
Venous thromboembolism (VTE) is an important cause of morbidity and mortality following major orthopaedic surgery. However, the incidence of VTE and the role of additional risk factors have not yet been well explored in Italian clinical practice. The objective of the study is to estimate the incidence of VTE in the 3 months following elective hip and knee replacement (HR, KR) in a large cohort of patients, and the association between some selected risk factors and the occurrence of VTE. A large cohort study based on the record linkage between automated archives of the National Health System was analysed. In particular, all the residents in the Lombardy Region (Italy) who underwent HR and KR between 2005 and 2008 were followed for 3 months after surgery. The odds ratio (OR) of VTE associated with selected known risk factors was estimated by multivariate logistic regression. Amongst the 69,770 patients included in the study, 2,393 experienced at least one VTE event during the follow-up; the overall risk of VTE after HR or KR was 3.4%. The adjusted odds of experiencing a VTE event was higher in male patients (OR 1.11; 95% confidence interval 1.01-1.21), aged 60 years or older (1.30; 1.00-1.68), undergoing KR (1.47; 1.35-1.61), with previous deep vein thrombosis (1.96; 1.20-3.19), pulmonary embolism (3.25; 1.84-5.75) or cancer (1.21; 1.00-1.46). In conclusion, the incidence of VTE after elective HR and KR in the Italian clinical practice is high. Our results suggest the need of optimising the management of thromboprophylaxis to further reduce postoperative VTE.

Abstract
OBJECTIVE To determine the incidence of venous thromboembolism (VTE) among patients with traumatic spinal cord injury (TSCI) in acute care settings that is attributable to extended length of stay (LOS), insurance status, and access to rehabilitation. DESIGN Population-based, retrospective cohort study. SETTING Levels I through III and undesignated trauma centers. PARTICIPANTS Patients with acute TSCI (N=3389) discharged from all acute care hospitals in South Carolina from 1998 through 2009, and a representative sample of patients with TSCI (n=186) interviewed 1 year later. INTERVENTIONS Not applicable. MAIN OUTCOME MEASURE VTE while in acute care. RESULTS Annual incidence of TSCI is 67.2 per million in the state of South Carolina, while the cumulative incidence of VTE is 4.1%. Patients with TSCI who developed VTE were nearly 4 times more likely (odds ratio [OR], 3.98; 95% confidence interval [CI], 2.57-6.17) to have been those who stayed 12 days or longer in acute care after adjusting for covariates. The adjusted mean LOS in acute care was 32.0 days (95% CI, 27.7-37.2) for patients with TSCI who had indigent insurance versus 11.3 days (95% CI, 4.9-17.6) for Medicare, and 18.5 days (95% CI, 14.5-22.5) for commercial insurance after adjusting for VTE, disposition, and year of discharge. Only 20% of the persons under indigent care received rehabilitation from accredited rehabilitation facilities in contrast to 60% under commercial insurance. CONCLUSIONS Fewer patients with TSCI under indigent care received postacute rehabilitation compared with Medicare or commercial insurance. Insurance status remains a major barrier to timely transfer to rehabilitation, leading to protracted LOS in acute care with increased risk of VTE.

Abstract
BACKGROUND Studies evaluating risk factors for in-hospital venous thromboembolism in children are limited by quality assurance of case definition and/or lack of controlled comparison. The objective of this study is to determine risk factors for the development of in-hospital venous thromboembolism in children. DESIGN AND METHODS In a case-control study at The Children's Hospital, Colorado, from 1(st) January 2003 to 31(st) December 2009 we employed diagnostic validation methods to determine pediatric in-hospital venous thromboembolism risk factors. Clinical data on putative risk factors were retrospectively collected from medical records of children with International Classification of Diseases, 9th edition codes of venous thromboembolism at discharge, in whom radiological reports confirmed venous thromboembolism and no signs/symptoms of venous thromboembolism were noted on admission. RESULTS We verified 78 cases of in-hospital venous thromboembolism, yielding an average incidence of 5 per 10,000 hospitalized children per year. Logistical regression analyses revealed that mechanical ventilation, systemic infection, and hospitalization duration of five days or over were statistically significant, independent risk factors for in-hospital venous thromboembolism (OR=3.29, 95%CI=1.53-7.06, P=0.002; OR=3.05, 95%CI=1.57-5.94, P=0.001; and OR=1.03, 95%CI=1.01-1.04, P=0.001, respectively). Using these factors in a risk model, post-test probability of venous thromboembolism was 3.6%. CONCLUSIONS These data indicate that risk of in-hospital venous thromboembolism in children with this risk factor combination may exceed that of hospitalized adults in whom prophylactic anticoagulation is indicated. Substantiation of these findings via multicenter studies could provide the basis for future risk-stratified randomized control trials of pediatric venous thromboembolism prevention.

Abstract
BACKGROUND To determine the effectiveness of pharmacologic prophylaxis in preventing clinically relevant venous thromboembolic (VTE) events and deaths after surgery. The Surgical Care Improvement Project recommends that VTE pharmacologic prophylaxis be given within 24 hours of the operation. The bulk of evidence supporting this recommendation uses radiographic end points. STUDY DESIGN The Surgical Care and Outcomes Assessment Program is a Washington State quality improvement initiative with data linked to hospital admission/discharge and vital status records. We compared the rates of death, clinically relevant VTE, and a composite adverse event (CAE) in the 90 days after elective, colon/rectal resections, based on receipt of pharmacologic prophylaxis (within 24 hours of surgery) at 36 Surgical Care and Outcomes Assessment Program hospitals (2005-2009). RESULTS Of 4,195 (mean age 61.1 ± 15.6 years; 54.1% women) patients, 56.5% received pharmacologic prophylaxis. Ninety-day death (2.5% vs 1.6%; p = 0.03), VTE (1.8% vs 1.1%; p = 0.04), and CAE (4.2% vs 2.5%; p = .002) were lower in those who received pharmacologic prophylaxis. After adjustment for patient and procedure characteristics, the odds were 36% lower for CAE (odds ratio = 0.64; 95% CI, 0.44-0.93) with pharmacologic prophylaxis. In any given quarter, hospitals where patients more often received pharmacologic prophylaxis (highest tertile of use) had the lowest rates of CAE (2.3% vs 3.6%; p = 0.05) compared with hospitals in the lowest tertile. CONCLUSIONS Using clinical end points, this study demonstrates the effectiveness of VTE pharmacologic prophylaxis in patients having elective colorectal surgery. Hospitals that used pharmacologic prophylaxis more often had the lowest rates of adverse events.

Abstract
BACKGROUND Inpatient VTE prophylaxis is underused. This study evaluated the effectiveness of the low-cost, multifaceted Australian National Inpatient Medication Chart (NIMC) intervention on improving the quality of VTE prophylaxis and reducing disease. The NIMC intervention incorporated (1) a VTE risk stratification and appropriate prophylaxis guidance tool, (2) a prophylaxis contraindication screening instrument, and (3) a prophylaxis prescription prompt. METHODS Retrospective analysis of 2,371 consecutive medical and surgical admissions was performed at a regional referral hospital over 1 year both before and after the intervention. Outcomes measured included the frequency of prophylaxis use, timing of prophylaxis initiation, adherence of the prescribed prophylaxis regimen to guidelines, incidence of VTE disease, and prophylaxis-related complications. RESULTS Following NIMC intervention, prophylaxis use increased from 52.7% to 66.5% in medical patients and from 77.5% to 89.1% in surgical patients (P < .001). This increase was still evident 12 months postintervention. After intervention, prophylaxis initiated on admission increased from 65.0% to 83.6% in medical patients and from 60.7% to 78.0% in surgical patients (P < .01); adherence rates to recommended guidelines increased from 55.6% to 71.0% in medical patients and from 53.6% to 75.6% in surgical patients (P < .01). More VTE risk factors independently triggered prophylaxis usage postintervention. The improved quality of prophylaxis did not significantly reduce VTE incidence (risk ratio, 0.88; 95% CI, 0.48-1.62). The rate of prophylaxis-related complications remained similar before and after intervention. CONCLUSIONS The multifaceted NIMC intervention resulted in a sustained increase in appropriate and timely VTE prophylaxis in medical and surgical inpatients.

Abstract
Venous thromboembolism (VTE) is the most preventable cause of death in hospitalized patients. Hospital-related VTE is associated with more than half of the VTE burden in a community, either in-hospital or after discharge. Selective thromboprophylaxis is recommended for patients at risk. Patient selection for thromboprophylaxis requires proper VTE risk stratification. VTE stratification may be achieved by either risk assessment models (RAM) or by models based on patient's illness and associated risk factors. Whatever the model, a thromboprophylatic recommendation should be formulated for each VTE risk category. VTE thromboprophylaxis may include general measures, mechanic compression procedures, pharmacological intervention or a combined approach. After many decades of consensus statements, a large proportion of at risk patients (20% to 75%) still does not receive proper thromboprophylaxis. This study aims to alert to the relevance of thromboprophylaxis and to suggest hospital thromboprophylatic strategies in a Brazilian setting.

Abstract
INTRODUCTION The aim was to determine the frequency with which thromboprophylaxis is prescribed, factors predicting its prescription, and the frequency of symptomatic venous thromboembolism in patients admitted with acute abdominal conditions. METHODS Charts of patients admitted with acute abdominal conditions that did not have surgery for at least 24 h following admission were audited to identify if thromboprophylaxis was prescribed, if it was prescribed appropriately, factors affecting its prescription, and the rate of symptomatic venous thromboembolism. RESULTS Of 350 patients (176 females, mean age 64.9 ± 18.6), 194 (55.4%) were admitted for bowel obstruction, 113 (32.3%) for biliary conditions, 14 (4.0%) for diverticulitis, 8 (2.3%) for pancreatitis, and 21 (6.0%) for other conditions. One hundred forty-two (40.6%) underwent surgery. Two hundred fifty-two (72.0%, 95% CI 67.3-76.7%) received thromboprophylaxis although only 199 (56.9%, 95% CI 51.7-62.1%) received adequate thromboprophylaxis. Hospital site and having surgery were associated with prescription of thromboprophylaxis. Twelve patients (3.4%, 95% CI 1.5-4.3%) developed symptomatic venous thromboembolism (nine deep venous thrombosis, three pulmonary embolism). CONCLUSIONS Despite patients admitted with acute abdominal conditions being at high risk for development of symptomatic venous thromboembolism, many do not receive adequate thromboprophylaxis. Further work is required to decrease this gap in care.

Abstract
The recommendations for anticoagulation in over 80 years old patients are based on the thromboembolic/bleeding risk relation. They add to the published recommendations for the specific indications. Low-molecular-weight heparin (LMWH) is used to prevent thromboembolism postoperatively. Compression stockings and/or intermittent pneumatic compression are used if bleeding risk is very high. The dose is increased starting at day two if the thromboembolic risk is very high. Bleeding and thromboembolic risks are re-evaluted daily. The antithrombotic therapy is adjusted accordingly. Prophylaxis of thromboembolism in patients with acute illnesses and bedrest is performed according postoperative care. Two-thirds of therapeutic doses of low-molecular-weight heparin are used to treat acute venous thromboembolism. Reduced renal function (creatinine clearance <30 ml/ min for most LMWHs or <20 ml/min for tinzaparin) should result in a further reduction of dose. Intensity and duration of prophylaxis of recurrent events with vitamin K antagonist or LMWH in malignancy follow current or herein described recommendations. Patients with atrial fibrillation are treated with vitamin K antagonists adjusted to an INR of 2-3 for prophylaxis of embolism. Further details of anticoagulant therapy should be in agreement with the national or international recommendations.

Abstract
Venous thromboembolism in adults is related to recent hospitalisation in approximately half of all cases and approximately half of all hospitalised adult patients are considered to be at risk by conventional criteria. Due to advances in surgical practice, the identification of surgical patients in need of prophylaxis has become less rather than more certain. Faster surgical technique, regional anaesthesia and early mobilisation are considered to reduce the risk of venous thromboembolism and hence possibly obviate the need for prophylaxis after early discharge from hospital. An increasing proportion of patients with hospital-acquired venous thromboembolism are medical patients, but the need to identify medical patients that require thromboprophylaxis is a new aspect of clinical practice for many physicians and prophylaxis remains under-utilised in non-surgical hospitalised patients. In this review prevention of hospital-acquired venous thromboembolism is considered as a patient safety issue in the context of changing clinical practice. Strategies for refining and validating risk assessment models and evaluating the effect of risk assessment and thromboprophylaxis are suggested.

Abstract
Venous thromboembolic events (VTE) occur in children at the time of surgery. Few guidelines about how to assess the risk and provide prophylaxis have been developed and published so far. It is uncertain if any of these guidelines have been adopted into clinical practice. The article discusses the specific differences of the haemostatic system throughout childhood, risk assessment, choice and dosing of antithrombotic agents, difficulties in drug monitoring and side effects of treatment including HIT. Current available recommendations and guidelines are summarized. Current evidence on which to base risk stratification and prevention of VTE for children undergoing surgery consists mainly of cohort studies, case series, case reports and expert opinion. Many suggestions are merely extrapolated from results from clinical trials in adults. Primary healthy children who undergo minor surgery including circumcision, herniotomy and appendectomy do not need antithrombotic prophylaxis. Children with multiple risk factors for VTE including severe underlying conditions and long-term immobilization, children with central venous lines and children with a history of VTE should be considered to receive VTE prophylaxis. Older children (Tanner II+) should be treated following adult guidelines. Standard unfractionated heparin and low molecular heparin are the most frequently recommended antithrombotic drugs. Decision for VTE prophylaxis must widely be based on individual risk assessment by experienced physicians. Newly developed scores and guidelines may provide assistance. Well designed clinical studies in children that provide proper evidence on risk assessment for VTE at the time of surgery and investigate safety and efficacy of antithrombotic prophylaxis/treatment are urgently needed.

Abstract
The last 50 years have witnessed a multitude of publications evaluating the efficacy, safety and cost effectiveness of many different thromboprophylaxis interventions. There is widespread consensus that thromboprophylaxis safely reduces morbidity and mortality. More than 25 evidence-based guidelines, published since 1986, also recommend routine thromboprophylaxis in the majority of hospitalized patients. As a result, thromboprophylaxis is recognized as a key safety priority for hospitals. Some of the remaining areas of controversy that will be discussed in this paper include the role of individual risk assessments to determine thrombosis risk and prophylaxis, replacement of low-dose heparin by low-molecular-weight heparin (LMWH), the optimal duration of prophylaxis, the role of combined thromboprophylaxis modalities, the safety of anticoagulant prophylaxis with regional analgesia, the use of LMWHs in chronic renal insufficiency, and the emerging role of new oral anticoagulants as thromboprophylactic agents. Despite the overwhelming evidence supporting thromboprophylaxis, rates of thromboprophylaxis use remain far from optimal. Successful implementation strategies to bridge this knowledge:care gap are the most important current challenges in this area. These strategies must be multifaceted, utilizing local, systems-based approaches as well as legislation and incentives that reinforce best practices.
