Abstract Introduction: The presence of hetero- (sickle trait) or homozygous (sickle disease) hemoglobin S gene is associated with increased risk of venous thromboembolism (VTE). However, sickle disease patients in particular are relatively young, lack common comorbid conditions that would qualify them for inpatient VTE prophylaxis (VTEP) and there are limited published data on trends of VTEP use in these populations. Methods: This was a retrospective analysis of all hospitalizations of sickle trait or disease adult medical patients occurring between January 2013 and December 2018 at three hospitals in Southeast Michigan, USA. Admissions for bleeding or thrombosis, requirement of intensive care stay or surgery, those occurring within 45 days of orthopedic surgery, as well as all patients already on anticoagulation or with known hypercoagulable states were excluded. Hospitalized controls were matched for race, age, sex and length of stay. Trends of VTEP use and predictive patient factors over multiple admissions were modeled using generalized estimating equations. Results: There were 803 sickle trait (525 patients; mean age 43 ± 19; 85% female) and 1020 sickle disease admissions (262 patients; mean age 34 ± 13; 57% female); all patients were Black. The percentage of hospitalizations in which subjects were offered any VTEP was similar to that of controls in both groups of interest (Figure); however, there were more encounters in which patients received greater than 50% of expected VTEP doses in the sickle trait (80% vs 51%; p<0.01) and in the sickle disease group (57% vs 45%; p<0.01). In multivariate analysis, compared to controls, odds of being offered VTEP were similar with sickle trait genotype (adjusted odds ratio [aOR] 0.78; p=0.15), but were higher with sickle disease genotype (aOR 1.45; p=0.02). Increasing age and longer hospital stay were also positive predictors. Within the sickle disease hospitalizations, odds of VTEP use showed significant variability with treatment site (aOR 1.87; p<0.01), whereas comorbid conditions, including a history of VTE prior to admission, or hemoglobin measurement and platelet count on admission did not predict VTEP use. By contrast, in exploring sickle trait admissions, there was no impact of treatment site, but obesity (aOR 1.83; p<0.01), tobacco abuse (aOR 1.64; p=0.03), heart failure (aOR 2.17; p=0.01), prior VTE (aOR 2.22; p=0.07), as well as higher admission hemoglobin (aOR 1.18 per 1 g/dL increase; p<0.01) and platelet count (aOR 1.01 per 10 3 increase; p=0.03) raised the odds of VTEP being offered. Conclusions: VTEP is underused in sickle trait and disease patients. There may be a trend towards offering more VTEP in sickle disease, but not in sickle trait, where the decision is driven by comorbid conditions rather than hemoglobin genotype. Patient refusal does not appear to play a major role, but the finding of significant inter-center variability suggests provider education may result in improved use as hemoglobin genotype is currently not part of risk stratification tools that help clinicians decide on inpatient VTEP.

Abstract Abstract 4683 PURPOSE: To review the presenting features, response to treatment and outcome in children diagnosed with idiopathic thrombocytopenic purpura (ITP) at the University of South Alabama, Children’s and Women’s Hospital and Specialty Clinic. METHODS: Using ICD code 287.3, data were collected from the specialty clinic’s medical records and hospital database for children diagnosed with ITP between January 2005 and September 2010. Recurrent and chronic ITP were defined as thrombocytopenia recurring within or more than 6 months of diagnosis, respectively. Univariate and multivariate logistic regression analyses were performed to evaluate variables associated with chronic ITP. RESULTS: Eight four patients were identified (M,F 1:1) with an average age of 70 months at diagnosis. Mean platelet count at presentation was 14k. Oral or nasal mucosal bleeding occurred in 19(23%) patients but none experienced a serious hemorrhage. Thirty three (39%) patients had an associated illness prior to diagnosis of ITP. Treatment consisted of intravenous immunoglobulin (IVIG) in 38(45%), WinRho in 11(13%), IVIG or WinRho followed by the other in 20(24%), data not available 8(10%) and no therapy in 7 patients (8%). Average platelet count at discharge and within 2 weeks after IVIG and WinRho was 57k, 337k and 57k, 375 respectively. Forty three (51%) were acute, 17(20%) became recurrent, and 24(29%) became chronic ITP. Bone marrow examination was performed in 26(30%) patients upon subsequent relapse but the diagnosis remained unaltered in all cases. Rituximab therapy was provided to five and splenectomy was performed in 7 patients. Four patients failed both modalities, all of whom currently are IVIG dependant. Age <5year (OR 0.12, 95%CI 0.22, 0.67, p=0.01) was protective against development of chronic ITP while platelet count >20k at presentation (OR 6.50, 95%CI 1.35, 31.30, p=0.02) and race other than white (OR 36.63, 95%CI 4.61, 291.09, p=0.001) were found to be significantly associated with the development of chronic ITP. Gender, mean platelet volume, total white cell count, and absolute lymphocyte count had no significant association. CONCLUSION: Our study supports the published data that patients with an initial platelet count >20k, older age and non-white race have an increased risk of progression to chronic ITP. Other published variables had no significant association in our analyses. Response to IVIG and WinRho was no different in our patients while rituximab or splenectomy did not lead to a complete resolution in refractory cases. Since bone marrow examination did not alter the diagnosis in any patient, we suggest that routine performance of this procedure may be omitted when a diagnosis of ITP is consistent with clinical history, physical examination and laboratory data.

SummaryAlthough the use of thromboprophylaxis is recommended for acutely ill medical patients at increased risk of venous thromboembolism (VTE), it remains unclear which risk assessment model (RAM) should be routinely used to identify at-risk patients requiring thromboprophylaxis. We therefore aimed to describe existing RAMs, and to compare these tools in terms of validity and applicability for clinical decisionmaking. We performed a comprehensive systematic search in MEDLINE from the date of initiation until May 2016 for studies in acutely ill medical patients investigating validity of RAMs for VTE. Two reviewers independently screened the title, abstract, and full text, and evaluated the characteristics of studies, and the composition, evidence of validation, and results on validity of the RAMs. We included 11 studies assessing eight RAMs: 4-Element RAM, Caprini RAM, a full logistic model, Geneva risk score, IMPROVE-RAM, Kucher Model, a “Multivariable Model”, and Padua Prediction Score. The 4-Element RAM, IMPROVE-RAM, Multivariable Model, and full logistic model had derivation by identifying factors with predictive power. The other four RAMs were empirically generated based on consensus guidelines, published data, and clinical expertise. The Kucher Model, the Padua Prediction Score, the Geneva Risk Score and the IMPROVE-RAM underwent multicenter external validation. The Kucher Model, the Padua Prediction Score, and the Geneva Risk Score improved rates of thromboprophylaxis or clinical outcomes. In conclusion, existing RAMs to evaluate the need of thromboprophylaxis in acutely ill medical patients are difficult to compare and none fulfills the criteria of an ideal RAM. Nevertheless, the adequacy of thromboprophylaxis may be improved by implementing one of the validated RAMs.

Abstract Thrombocytopenia is common in patients admitted to the intensive care unit, with a reported prevalence of 8-68% and incidence of 13-44% in published series. Those who develop thrombocytopenia in an ICU have a statistically increased risk of ICU mortality, duration of mechanical ventilation, and platelet, RBC, and FFP transfusions. Few studies have examined the occurrence and risk factors for thrombocytopenia in non-ICU hospitalized patients. The only systematic investigation of thrombocytopenia in the non-ICU hospitalized medical population dates to 1989, predating modern diagnostic assays for a variety of infectious and drug-induced causes of thrombocytopenia. We, therefore, undertook this study to characterize the incidence and causes of thrombocytopenia in the general medical, non-ICU patient population at a tertiary care hospital. For this study, we performed a single-institutional retrospective analysis of patients admitted to a general medical ward at a tertiary care medical center (Duke University Hospital). Inclusion criteria included all adult patients (>18 years) admitted from the emergency department to the general medicine floors during the calendar year defined as 01/2014-01/2015. Exclusion criteria included pre-existing thrombocytopenia, ICU admission, or patients undergoing chemotherapy. Primary endpoints included patients with incident thrombocytopenia, defined as a platelet count on admission greater than 150 x 10^9/L with subsequent platelet counts decreasing to < 150 x 10^9/L. Patients meeting these criteria were evaluated for admission diagnosis, pertinent past medical history, cause of thrombocytopenia (infection, splenic sequestration, drugs, surgery, liver disease), cost of admission, and prognosis. Preliminary evaluation of patients admitted to the general medical service in 2014 reveals ~711 patients who meet inclusion criteria. Of patients developing absolute thrombocytopenia, 56% experienced a platelet count fall of greater than 30%. Those with incident thrombocytopenia greater than 30% had a statistically significant increase in mortality (n=36/399) compared to those with milder thrombocytopenia (n=13/312), (9.0% versus 4.2%, p<0.05), and had an increased length of stay (12.6 days versus 6.8 days, p<0.01). In patients who developed absolute thrombocytopenia, review of diagnosis codes associated with thrombocytopenia reveal a predominance of infectious etiologies (43%; sepsis, severe sepsis, septic shock, bacteremia, urinary tract infection/pyelonephritis, pneumonia, Clostridium difficile colitis). These results are similar to prior published data which suggests infection as a leading cause of incident thrombocytopenia in non-ICU hospitalized patients. Additional studies are underway to delineate non-infectious causes of thrombocytopenia. Disclosures No relevant conflicts of interest to declare.

The Impact

Background: Persistent wound drainage and venous thromboembolism (VTE) are potential complications of total joint arthroplasty, and these risks can be challenging to balance in clinical practice. Anecdotal observation has suggested that following joint arthroplasty, persistent wound drainage occurs more frequently with higher body weight and higher doses of tinzaparin when compared with lower body weight and lower doses of tinzaparin. Objective: The overall purpose of this study was to describe the impact of a tinzaparin weight-band dosing table for VTE prophylaxis on wound healing, thrombosis, and bleeding outcomes in patients undergoing total joint arthroplasty. Methods: This retrospective chart review included patients who underwent total hip or knee arthroplasty and received tinzaparin for thromboprophylaxis per their weight-banding category. The primary outcome was the incidence of persistent wound drainage. Secondary outcomes include the occurrence of VTE and clinically important bleeding during hospital admission. Results: A total of 231 patients were included in the analysis. There was no significant difference in persistent wound drainage between the 3 weight categories, and there were no differences in rates of VTE or clinically important bleeding. Concurrent use of low-dose acetylsalicylic acid was associated with a 3-fold increased risk of persistent wound drainage (risk ratio = 3.35; 95% CI = 2.14-5.24; P = 0.00003). Conclusion and Relevance: In joint arthroplasty patients, we observed no significant difference in rates of persistent wound drainage between various weight categories receiving different weight-banded doses of tinzaparin. Our results do not suggest that the current weight-band dosing table for tinzaparin needs to be adjusted to optimize patient outcomes.

Plasma von Willebrand factor (VWF) and platelet reactivity are both risk factors for venous thromboembolism (VTE), and VWF can promote hemostasis by interaction with platelets. In this study, we explored the combined effects of plasma VWF and platelet measures on the risk of incident VTE. A population-based nested case-control study with 403 cases and 816 controls was derived from the Tromsø Study. VWF, platelet count and mean platelet volume (MPV) were measured in blood samples drawn at baseline. Odds ratios (ORs) with 95% confidence intervals (CIs) for VTE were estimated across VWF tertiles, within predefined MPV (&lt;8.5, 8.5-9.5, ≥9.5 fL) and platelet count (&lt;230, 230-299, ≥300·109 L-1) strata. Here, participants with VWF levels in the highest tertile and MPV ≥9.5 fL had an OR of 1.98 (95% CI 1.17-3.36) for VTE compared with those in the lowest VWF tertile and with MPV &lt;8.5 fL in the age- and sex-adjusted model. In the joint exposure group, 48% (95% CI 15% to 96%) of VTEs were attributable to the biological interaction between VWF and MPV. Similarly, individuals with VWF in the highest tertile and platelet count ≥300·109 L-1 had an OR of 2.91 (95% CI 1.49-5.67) compared with those with VWF in the lowest tertile and platelet count &lt;230, and 39% (95% CI -2% to 97%) of VTEs in the joint exposure group were explained by the interaction. Our results suggest that both platelet reactivity and platelet count interact biologically with high plasma VWF, resulting in an increased risk of incident VTE.

Despite the high morbidity and mortality associated with venous thromboembolism in hospitalized medical patients with a number of risk factors, and large evidence that prophylaxis is effective, prophylaxis rates remain elusive in medically ill patients. Furthermore, in patients with renal failure, prophylaxis often is omitted or sub-optimal, due to fear of provoking hemorrhage. Patients with end-stage renal disease often have platelet deficits. Low molecular weight heparin (LMWH) therapy may also be difficult to manage in these cases because LMWH clearance is largely dependent on the kidneys. Administration of LMWH to patients with some degree of renal failure may lead to bioaccumulation of anti-Xa activity with an increased risk of bleeding. In recent years, LMWH has largely replaced unfractionated heparin (UFH) for the treatment and prophylaxis of thromboembolic disease. LMWHs have been shown to be superior to UFH in the prevention of venous thromboembolism. They are also easier to administer and do not require laboratory monitoring. However, several case reports and a metaanalysis indicate that the use of LMWHs at therapeutic doses in patients with advanced renal failure can be associated with major bleeding with serious adverse effects. In this paper, we review recent evidence supporting the safety of LMWHs at prophylactic doses in patients with mild or moderate renal disease. Current evidence suggests that bioaccumulation of enoxaparin (the most widely used LMWH) can occur when the drug is used at standard therapeutic doses in patients with severely impaired renal function. This risk can be reduced by empiric dose reduction or monitoring of anti-Xa heparin levels.

IntroductionPatients with an intracerebral haemorrhage are at increased risk of venous thromboembolism. Pharmacotherapy and pneumatic compression devices are capable of preventing venous thromboembolism, however both interventions have limitations. There are no head-to-head comparisons between these two interventions. To address this knowledge gap, we plan to perform a systematic review and network meta-analysis to examine the comparative effectiveness of pharmacological prophylaxis and mechanical compression devices in the context of intracerebral haemorrhage.Methods and analysisMEDLINE, PUBMED, EMBASE, CENTRAL, ClinicalTrials.gov and the Internet Stroke Trials Registry will be searched with assistance from an experienced information specialist. Eligible studies will include those that have enrolled adults presenting with spontaneous intracerebral haemorrhage and compared one or more of the respective interventions against each other and/or a control. Primary outcomes to be assessed are occurrence of new venous thromboembolism (deep vein thrombosis and/or pulmonary embolism) and haematoma expansion, defined as a significant enlargement of baseline haemorrhage or new haemorrhage occurrence. Both randomised and non-randomised comparative studies will be included. Data on participant characteristics, study design, intervention details and outcomes will be extracted. Study quality will be assessed using the Cochrane Risk of Bias Tool and the Robins-I tool. Bayesian network meta-analyses will be performed to compare interventions based on all available direct and indirect evidence. If the transitivity assumption for network meta-analysis cannot be met, we will perform a qualitative assessment.Ethics and disseminationFormal ethics is not required as primary data will not be collected. The findings of this study will be disseminated through conference presentations, and peer-reviewed publications. In an area of clinical practice where equipoise exists, the findings of this study may assist in determining which treatment intervention is most effective in venous thromboembolism prevention.PROSPERO registration numberCRD42018090960.

Background: Patients with hepatocellular carcinoma (HCC) are at an increased risk for developing venous thromboembolism (VTE)- mainly portal venous thrombosis (PVT). Malignancy and liver cirrhosis ( 80%-90% of HCC cases are related to cirrhosis) are conditions that can perturb the hemostatic balance towards a prothrombotic state. Also, these patients with HCC are at high risk for gastrointestinal bleeding (GIB), making thromboprophylaxis and anticoagulation a treatment challenge. Additional information regarding the outcomes and severity of both VTE and GIB in patients with HCC would be useful to guide clinical decision-making Aim: To determine the rates, inpatient mortality, length of stay (LOS) and hospital cost of VTE and GIB-related admissions in patients with hepatocellular carcinoma. Method: We used ICD-9-CM and ICD-10-CM codes to identify hospitalizations from 2007 to 2016 that included HCC with primary discharge diagnoses of GIB or VTE. Linear trends in the rate of GIB and VTE, as well as in-hospital mortality, LOS, and inflation-adjusted hospital cost (in 2016 US dollars), were evaluated using Daniel's test; piecewise slopes were used as needed. All analyses accounted for the NIS sampling design with updated hospital trend weights used as appropriate. SAS v. 9.4 was used for all analyses. Results: Between 2007 and 2016, we identified 6,527,871 hospitalizations with HCC and a primary discharge diagnosis of GIB (3,517,059; 53.9%) or VTE (3,010,812; 46.1%). From 2007 to 2010, a decreasing trend was observed in the rate of GIB diagnoses (55.5% to 51.6%, ptrend < .001), whereas an increasing trend was observed for VTE diagnoses (44.5% to 48.4%, ptrend < .001). By contrast, from 2010 to 2016, an increasing trend was observed in GIB (51.6% to 55.2%, ptrend < .001), whereas a decreasing trend was observed in VTE (48.4% to 44.8%, ptrend < .001). For in-hospital mortality, a decreasing trend was observed for GIB (2.3% to 1.9%, ptrend < .001), whereas a decreasing trend was observed in VTE until 2012 (1.8% to 1.5%, ptrend < .001), after which no trend was indicated (1.5% to 1.6%, ptrend = .337). Although decreasing trends in LOS were observed for GIB (3.4 days to 3.2 days, ptrend < .001) and VTE (4.3 days to 3.3 days, ptrend < .001), increasing trends were observed for inflation-adjusted hospital cost for both GIB ($6,996 to $7,707, ptrend < .001) and VTE ($7,283 to $7,584, ptrend = .048). Conclusion: In this NIS cohort of hospitalized patients with HCC, GIB was more frequently observed than VTE. Trends observed in the rates of GIB and VTE went in opposite directions. In general decreasing trends were observed in in-hospital mortality and LOS for both VTE and GIB. By contrast, increasing trends were observed in the hospital cost for both diagnoses. Clinicians should balance benefits against risks when deciding VTE prophylaxis and treatment in patients with HCC. Future studies are needed to determine the ideal agent and specific dosages to treat HCC-associated VTE. Disclosures No relevant conflicts of interest to declare.

The incidence of venous thromboembolism (VTE) in peritoneal malignancies can approach 30 to 50 per cent without prophylaxis. Prophylaxis in cytoreductive surgeries (CRS) presents a challenge to preoperative heparin-based therapy because of an increased risk of coagulopathy and potential for bleeding. Herein, we report the large series of CRS and hyperthermic intraperitoneal chemotherapy receiving dextran-40 prophylaxis. Retrospective chart review of peritoneal malignancies patients undergoing CRS at University of Nebraska Medical Center identified 69 individuals who received dextran-40 between 2010 and 2013. The incidences of VTEs, perioperative bleeding, complications, morbidity, and mortality were determined in-hospital and at 90 days. Of the 69 patients treated, the 30-day VTE rate was 8.7 per cent, and no pulmonary embolisms, bleeding, anaphylactoid reaction, or mortality were observed with dextran usage. The specific VTE events included three upper extremity and three lower extremity VTEs. No additional VTE events were identified between 30 and 90 days. In conclusion, dextran-40 prophylaxis was not associated with any perioperative bleeding events, and the observed incidence of VTE was comparable to reported heparin-based prophylaxis in CRS/hyperthermic intraperitoneal chemotherapy patients. This data supports further exploration of dextran-40 as a VTE prophylactic agent in complex surgical oncology cases.
