Venous Thromboembolism Risk and Adequacy of Prophylaxis in High Risk Pregnancy in the Arabian Gulf. Curr Vasc Pharmacol 2017; 14:368-73. [PMID: 26517701 PMCID: PMC4997930 DOI: 10.2174/1570161113666151030105431] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/15/2015] [Revised: 09/30/2015] [Accepted: 10/01/2015] [Indexed: 12/17/2022]
Abstract
Objectives: To estimate the prevalence of venous thromboembolism (VTE) risk factors in pregnancy and the proportion of pregnancies at risk of VTE that received the recommended prophylaxis according to the American College of Chest Physicians (ACCP) 2012 published guidelines in antenatal clinics in the Arabian Gulf. Methods: The evaluation of venous thromboembolism (EVE)-Risk project was a non-interventional, cross-sectional, multi-centre, multi-national study of all eligible pregnant women (≥17 years) screened during antenatal clinics from 7 centres in the Arabian Gulf countries (United Arab Emirates, Kuwait, Bahrain, Qatar and Oman). Pregnant women were recruited during a 3-month period between September and December 2012. Results: Of 4,131 screened pregnant women, 32% (n=1,337) had ≥1 risk factors for VTE. Common VTE risk factors included obesity (76%), multiparity (33%), recurrent miscarriages (9.1%), varicose veins (6.9%), thrombophilia (2.6%), immobilization (2.0%), sickle cell disease (2.8%) and previous VTE (1.6%). Only 8.3% (n=111) of the high risk patients were on the recommended VTE prophylaxis. Enoxaparin was used in 80% (n=89) of the cases followed by tinzaparin (4%; n=4). Antiplatelet agents were prescribed in 11% (n=149) of pregnant women. Of those on anticoagulants (n=111), 59% (n=66) were also co-prescribed antiplatelet agents. Side effects (mainly local bruising at the injection site) were reported in 12% (n=13) of the cases. Conclusion: A large proportion of pregnant women in the Arabian Gulf countries have ≥1 VTE risk factor with even a smaller fraction on prophylaxis. VTE risk assessment must be adopted to identify those at risk who would need VTE prophylaxis.

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
Aim. To reduce the number of preventable hospital-acquired venous thromboembolic events (HA-VTE) and to improve the quality of VTE prophylaxis at multiprofile hospital. Materials and methods. A comprehensive approach to preventing HA-VTE was developed, which involved the global trigger tool method to assess adverse events, as well as the computerized clinical decision support system (CDSS) to prevent HA-VTE on the basis of relevant clinical practice guidelines, and HA-VTE registry. Results. A total of 50 patients (15 men, 35 women; their median age was 70.5 years) with HA-VTE were included in the HA-VTE registry in January 2014 to June 2015. Assessment of a trend in the prevalence of HA-VTE when introducing CDSS to prevent VTE showed its statistically significant decline in the total number of HA-VTE cases (χ2=7.325, df=1; p=0.0068) and in that of HA-VTE in surgical patients (χ2=7.266, df=1; p=0.0070). The statistical significance of χ2 for linear trend was not achieved for medical patients, which is probably due to the small sample size (χ2=2.764, df=1; p=0.0964). While introducing CDSS, there was a statistically significant reduction in the incidence of postoperative VTE from 8.76 to 4.17 cases per 1000 interventions (χ2=5.347, df=1; p=0.0208; the absolute values of HA-VTE and surgical interventions were used for the calculation). Conclusion. The proposed comprehensive approach can substantially increase the detection rate of HA-VTE and decrease its incidence rates. This requires a personified assessment of the risk of VTE and hemorrhage in all hospitalized patients on day 1 of their admission, timely initiation of recommended VTE prophylaxis, and dynamic assessment of the risk of VTE and hemorrhage for timely correction of the prophylaxis.

Abstract
Transition from the hospital into the outpatient setting is a critical event for the appropriate provision of VTE prophylaxis. Data for this transition for the situation in Germany is scant. This was a retrospective, observational study in patients receiving in-hospital thromboprophylaxis and discharged with or without a recommendation to continue. Patient with previous thromboembolism were excluded. A total of 3,211 patients were identified by 518 physicians of which 2,853 had all data available for the present analysis; mean patient's age was 57.4 ± 17.5 (SD) years, 48.2% were male and bodyweight was 79.8 ± 16.1 kg. During hospitalization 95.5% of surgical and 84.0% of medical patients received any thromboprophylaxis, the mean hospital duration being 12.7 ± 20.3 days. Surgical patients had high, medium and low risk in 53.8, 37.1 and 9.1%, respectively. Medical patients had high, medium and low risk in 78.8, 19.8 and 1.4%. A hospital recommendation to continue thromboprophylaxis was given to 84.6% (95% CI 83.1-85.9%) of surgical and 64.9% (95% CI 59.1-70.6%) of medical patients and implemented in 96.6 and 94.3%, respectively. On the other hand, in patients without a respective hospital recommendation (15.4% of surgical and 35.1% of medical patients), thromboprophylaxis was continued in 65.3% of surgical and 73.1% of medical patients because of high risk. Our data illustrate acceptable rates of prophylaxis in surgical and medical patients in Germany. As the results show, it is essential that not only hospital physicians are aware of the actual risk at discharge, but office based physicians assess thromboembolic risk.

Abstract
Venous thromboembolism (VTE) is a major cause of morbidity and mortality and is associated with substantial healthcare costs. Identification of patients at risk of developing VTE enables appropriate thromboprophylaxis to be implemented. Although no predisposing risk factors can be identified in many patients in whom VTE develops, most have at least one underlying risk factor which can be categorized according to whether it confers low, moderate, or high risk. Clinical trials have demonstrated the effectiveness of thromboprophylaxis, both non-pharmacological and pharmacological, in a host of medical settings and there is sufficient evidence to support routine prophylaxis in many groups of patients. The implementation of decision making tools based on risk factor assessment improves the prescription of appropriate VTE prophylaxis. Nonetheless, thromboprophylaxis is often inadequate, with haphazard risk assessment and application of guidelines, leading to easily preventable instances of VTE. The most commonly used agents for pharmacological thromboprophylaxis of VTE are low dose unfractionated heparin; a low molecular weight heparin such as dalteparin, enoxaparin or tinzaparin; fondaparinux; warfarin; or aspirin. However, these have a number of drawbacks, principally the need for parenteral administration (with heparins) and frequent coagulation monitoring (with warfarin). The optimal anticoagulant would be orally administered, with a wide therapeutic window, rapid onset of action, predictable pharmacodynamics and pharmacokinetics, minimal interactions with food and other drugs, an ability to inhibit free and clot-bound coagulation factors, low, non-specific binding, and no requirement for routine coagulation monitoring or dose adjustment. A number of novel, single-target oral anticoagulants have been developed that appear to fulfill many of these requirements. This narrative review discusses the use of guidelines and risk assessment tools to identify patients at risk of VTE; it provides an overview of appropriate prophylaxis strategies in these patients with a summary of clinical trial results with novel oral anticoagulants.

Abstract
Little is known about national trends of pulmonary embolism (PE) hospitalizations and outcomes in older adults in the context of recent diagnostic and therapeutic advances. Therefore, we conducted a retrospective cohort study of 100% Medicare fee-for-service beneficiaries hospitalized from 1999 to 2010 with a principal discharge diagnosis code for PE. The adjusted PE hospitalization rate increased from 129/100,000 person-years in 1999 to 302/100,000 person-years in 2010, a relative increase of 134% (p <0.001). Black patients had the highest rate of increase (174 to 548/100,000 person-years) among all age, gender, and race categories. The mean (standard deviation) length of hospital stay decreased from 7.6 (5.7) days in 1999 to 5.8 (4.4) days in 2010, and the proportion of patients discharged to home decreased from 51.1% (95% confidence interval [CI] 50.5 to 51.6) to 44.1% (95% CI 43.7 to 44.6), whereas more patients were discharged with home health care and to skilled nursing facilities. The in-hospital mortality rate decreased from 8.3% (95% CI 8.0 to 8.6) in 1999 to 4.4% (95% CI 4.2 to 4.5) in 2010, as did adjusted 30-day (from 12.3% [95% CI 11.9 to 12.6] to 9.1% [95% CI 8.5 to 9.7]) and 6-month mortality rates (from 23.0% [95% CI 22.5 to 23.4] to 19.6% [95% CI 18.8 to 20.5]). There were no significant racial differences in mortality rates by 2010. There was no change in the adjusted 30-day all-cause readmission rate from 1999 to 2010. In conclusion, PE hospitalization rates increased substantially from 1999 to 2010, with a higher rate for black patients. All mortality rates decreased but remained high. The increase in hospitalization rates and continued high mortality and readmission rates confirm the significant burden of PE for older adults.

Abstract
Hospitalized acutely ill patients face high risk for venous thromboembolism (VTE) unless appropriate thromboprophylaxis is applied. This study aimed to determine VTE prophylaxis practices for inpatients in Turkey and to evaluate the impact of physicians’ training via a modified “Standard Medical Patients’ VTE Risk Assessment Model (MERAM).” A total of 607 inpatients included in this national multicenter noninterventional observational registry were evaluated in terms of demographics, VTE risk, and preventive measures at 2 consecutive cross-sectional visits. Physicians were asked to complete a questionnaire on current VTE method risk assessment and other models including MERAM. The VTE prophylaxis rates significantly increased from 49.4% to 62.4% between visits ( P < .05). The lack of risk evaluation decreased from 74.6% to 19.5% ( P < .001). Percentage of physicians using prophylaxis and use of MERAM increased between visits. Physician training proved effective for providing general “awareness” of VTE prophylaxis and led to higher rates of risk assessment model-based appropriate VTE prophylaxis.

Abstract
Venous thromboembolism (VTE) is a well-recognized life-threatening complication in the intensive care unit (ICU). However, no data have been reported regarding the prevalence and methods of prevention of VTE in Japanese ICUs. This study aimed to document the current practice of VTE prevention across a broad sample of medical-surgical ICU patients in Japan. In November 2010, we performed a point-prevalence survey of Japanese ICUs in training facilities for intensive care specialists. We recorded data from five consecutive ICU patients in each facility at any time on the day of the survey. A total of 470 patients were registered in this study. VTE prophylaxis was received by 85.3 % of participants. Of these, 69.8 % received mechanical prophylaxis and 12.5 % received pharmacological methods, with 17.7 % receiving both methods. Analyzing a comparison of the presence or absence of a hospital prevention protocol, the protocol group had higher rates of receiving prophylaxis (88.8 % vs. 80.0 %, P < 0.01) than the no-protocol group. In conclusion, VTE prophylaxis by mechanical methods was the main method in a high number of medical-surgical ICU patients in Japan. The ICUs with a hospital VTE prevention protocol in place performed significantly higher rates of prophylaxis than those without a protocol.

Abstract
Venous thromboembolism (VTE) is a potentially serious complication occurring in 1%–2% of hospitalized medical patients. Despite this low absolute risk, as many as 82% of medical patients are considered to be at increased risk of developing VTE and are eligible for medical thromboprophylaxis. In this commentary, The author will discuss the main findings of a recent paper published in Clinical Epidemiology that questions the large proportion of individuals who are eligible for medical thromboprophylaxis, and also discuss the potential implications for the prevention of VTE. The recent paper demonstrated that when a population is divided into high- and low-risk groups, the maximum absolute risk depends on the inverse of the proportion of patients that is considered to be high risk. Consequently, even an effective treatment will only result in a small reduction in the absolute risk when the high-risk group comprises the largest proportion of this population. For medical thromboprophylaxis, this implies that even patients considered to be at high-risk for developing VTE have a maximum absolute VTE risk of 2% when the overall risk is 1.6%. Therefore, even an effective preventive initiative will only result in a small risk reduction. This small potential benefit should be weighed against potential harms associated with prophylaxis, mainly bleeding events. Still, there may be a reasonable overall balance between prevention of pulmonary embolism and major bleeding, mainly because major bleeding events are rare. Nonetheless, this discussion underscores that future risk prediction models should aim to predict the benefits and harms in individual patients in order to provide optimal care for the right patients.

Abstract
Pulmonary embolism is the third most common cause of death from cardiovascular disease after heart attack and stroke. Sequelae occurring after venous thromboembolism include chronic thromboembolic pulmonary hypertension and post-thrombotic syndrome. Venous thromboembolism and atherothrombosis share common risk factors and the common pathophysiological characteristics of inflammation, hypercoagulability, and endothelial injury. Clinical probability assessment helps to identify patients with low clinical probability for whom the diagnosis of venous thromboembolism can be excluded solely with a negative result from a plasma D-dimer test. The diagnosis is usually confirmed with compression ultrasound showing deep vein thrombosis or with chest CT showing pulmonary embolism. Most patients with venous thromboembolism will respond to anticoagulation, which is the foundation of treatment. Patients with pulmonary embolism should undergo risk stratification to establish whether they will benefit from the addition of advanced treatment, such as thrombolysis or embolectomy. Several novel oral anticoagulant drugs are in development. These drugs, which could replace vitamin K antagonists and heparins in many patients, are prescribed in fixed doses and do not need any coagulation monitoring in the laboratory. Although rigorous clinical trials have reported the effectiveness and safety of pharmacological prevention with low, fixed doses of anticoagulant drugs, prophylaxis remains underused in patients admitted to hospital at moderate risk and high risk for venous thromboembolism. In this Seminar, we discuss pulmonary embolism and deep vein thrombosis of the legs.

Abstract
BACKGROUND Compliance with venous thromboembolism (VTE) prophylaxis is poor. OBJECTIVES We sought to determine whether a simple electronic reminder applicable to all hospitalized patients would increase prophylaxis rates and reduce VTE rates. METHODS An electronic reminder was added to the electronic medical record admission note used by all services in our hospital. Prophylaxis, VTE and bleeding rates before and after implementation were compared. Data were analyzed with sas version 9.1. RESULTS Among all adult medical and surgical patients admitted to our hospital during the time periods studied, 42.8% (1236/2888) before and 60.0% (1410/2350) after the reminder was added received appropriate prophylaxis as per American College of Chest Physicians (ACCP) guidelines (P < 0.001). The difference reached significance for both medical (51.0% vs. 68.9%; P < 0.001) and surgical (48.0% vs. 61.0%; P < 0.001) services. Fewer patients were diagnosed with VTE after our reminder was added (1.1% vs. 0.3%; P = 0.001), and there was a trend towards fewer bleeds (1.1% vs. 0.6%; P = 0.09). The presence of the reminder was an independent predictor for prophylaxis being given (odds ratio [OR] 1.92, 95% confidence interval [CI] 1.70-2.18; P < 0.001), and was independently associated with a decreased risk for VTE (OR 0.30, 95% CI 0.14-0.64; P = 0.003) after adjustment for other VTE risk factors. CONCLUSION Adding an electronic reminder to the admission note improved prophylaxis rates and reduced VTE rates across services. The system is easily reproducible and applicable to other facilities. The improvement obtained was modest, so additional measures will probably be needed to optimize prophylaxis rates.
