Low anti-factor Xa level predicts 90-day symptomatic venous thromboembolism in surgical patients receiving enoxaparin prophylaxis: a pooled analysis of eight clinical trials.
This study examined whether low anti-factor Xa (aFXa) level predicts 90-day symptomatic venous thromboembolism (VTE) in surgical patients receiving enoxaparin prophylaxis. The authors conducted a pooled analysis of 8 clinical trials from a single institution over a 4-year period. Among 985 patients, 2.3% had symptomatic 90-day VTE, 4.2% had 90-day clinically relevant bleeding, and 2.1% had major bleeding. Patients with initial low aFXa were significantly more likely to have 90-day VTE than patients with adequate or high xFXa (4.2% vs 1.3%). This relationship was significant for patients who received enoxaparin twice daily as opposed to once a day. No association was seen between high xFXa and 90-day clinically relevant bleeding or major bleeding.

Electrocardiographic findings associated with early clinical deterioration in acute pulmonary embolism.
Investigators sought to determine associations of early ECG patterns with clinical deterioration (CD) within 5 days and with RV abnormality (abnlRV) by echocardiography in PE. They found that supraventricular tachycardia was an independent predictor of CD, while T-wave inversion, incomplete right bundle branch block, ST-segment elevation aVR, sinus tachycardia, and S1-Q3-T3 were independent predictors of abnlRV. They suggested that finding one or more of these ECG patterns may increase considerations for performance of echocardiography to look for RV abnormalities and, if present, inform concerns for early clinical deterioration.

Which hospital-acquired conditions matter the most in trauma? An evidence-based approach for prioritizing trauma program improvement.
The purpose of this study was to quantify and compare the impacts of six different hospital-acquired conditions (HACs) on early clinical outcomes and resource utilization in hospitalized trauma patients. The researchers included 529,856 adult patients from the 2013 to 2016 American College of Surgeons Trauma Quality Improvement Program Participant Use Data Files with 5 days or longer of hospitalization and had an Injury Severity Score of 9 or higher. The study found the incidences of HACs were: pneumonia, 5.2%; urinary tract infection, 3.4%; venous thromboembolism, 3.3%; surgical site infection, 1.3%; pressure ulcer, 1.3%; and central line-associated blood stream infection, 0.2%. The HAC of pneumonia demonstrated the largest association with in-hospital outcomes and resource utilization. The researchers reported that prevention of pneumonia within the study group would have resulted in estimated reductions of: 22.1% for end organ dysfunction, 8.7% for prolonged hospitalization, 7.8% for mortality, 7.1% for prolonged intensive care unit stay, and 6.8% for need for mechanical ventilation. The researchers concluded that pneumonia prevention should be a priority activity in program improvement efforts.

Can right ventricular assessments improve triaging of low risk pulmonary embolism?
Researchers sought to determine if right ventricle (RV) assessment variables add prognostic accuracy for 5-day clinical deterioration in patients classified low risk by the Simplified Pulmonary Embolism Severity Index and to determine the prognostic importance of RV assessments compared to other variables and to each other. They found that a pulmonary embolism triaging strategy with RV imaging assessments had superior prognostic performance at classifying low risk for 5-day clinical deterioration versus one without.

Derivation and validation of a risk factor model to identify medical inpatients at risk for venous thromboembolism.
This study’s objective was to compare multiple risk assessment models for hospitalized patients at high risk for venous thromboembolism (VTE). The authors developed a derivation cohort using 6 years of data from 12 hospitals to identify risk factors associated with developing VTE within 14 days of admission. The cohort included 155,026 patients with a 14-day VTE rate of 0.68%. The final multivariable model contained 13 risk factors and good calibration, and performance was evaluated using the C-statistic. The temporal validation cohort had 53,210 patients with a VTE rate of 0.64% and the external cohort had 23,413 patients and a rate of 0.49%. The Cleveland Clinic Model (CCM) outperformed both the Padua and IMPROVE models in the temporal cohort. In the external cohort the CCM C-statistic was similar to Padua and outperformed IMPROVE.

Natural language processing for the surveillance of postoperative venous thromboembolism.
The objective of the study was to develop a portal natural language processing approach to aid in the identification of postoperative venous thromboembolism events from free-text clinical notes. The investigators concluded that accurate surveillance of postoperative venous thromboembolism may be achieved using natural language processing on clinical notes in 2 independent health care systems. They indicated that these findings suggest natural language processing may augment manual chart abstraction for large registries such as National Surgical Quality Improvement Program.

Association between missed doses of chemoprophylaxis and VTE incidence in a statewide colectomy cohort.
The objectives of this study were to assess the incidence of missed doses of inpatient venous thromboembolism (VTE) chemoprophylaxis after colectomy in a statewide patient cohort and to examine the association between missed chemoprophylaxis doses and postoperative VTE. Findings showed that 13% of post-colectomy inpatients did not receive all prescribed doses of inpatient VTE chemoprophylaxis, and at least 1 missed dose of chemoprophylaxis was associated with an over twofold increased incidence of VTE among patients at high risk for VTE. Recommendations included verifying that patients receive all prescribed doses, identifying why doses are missed, and instituting quality improvement efforts to ensure patients receive all appropriate doses.

Inappropriate prescription of direct oral anticoagulant starter packs.
This study looked at the rates of inappropriate prescription of direct oral anticoagulant starter packs using a retrospective analysis of national outpatient pharmacy claims from 2015 to 2018. Inappropriate prescription is defined as a prescription without a venous thromboembolism diagnosis within the prior 45 days or a prescription with a prior starter pack fill within the past 45 days. A total of 3711 prescriptions were identified, representing 3634 unique patients. Mean patient age was 62.8 years and 50.4% were females. There were 770 (20.7%) prescriptions defined as potentially inappropriate. Patients prescribed inappropriate fills were likely to be slightly older than patients with appropriate fills (64.7 vs 62.4 years). There was no significant difference in race or geographic location among the two groups.

A postdischarge venous thromboembolism risk calculator for inflammatory bowel disease surgery.
Guidelines recommend extended chemoprophylaxis for venous thromboembolism in high-risk patients having operations for inflammatory bowel disease. Quantifying patients' risk of venous thromboembolism, however, remains challenging. In this study, the investigators sought (1) to identify factors associated with postdischarge venous thromboembolism in patients undergoing colorectal resection for inflammatory bowel disease and (2) to develop a postdischarge venous thromboembolism risk calculator to guide prescribing of extended chemoprophylaxis.

Oral glucocorticoids and incident treatment of diabetes mellitus, hypertension, and venous thromboembolism in children.
The purpose of this study was to quantify rates of incident treatment for diabetes mellitus, hypertension, and venous thromboembolism (VTE) associated with oral glucocorticoid exposure in children aged 1-18 years. Participants were identified using US Medicaid claims data and included more than 930,000 children diagnosed with autoimmune diseases or a nonimmune comparator condition. Findings showed strong dose-dependent relationships between current glucocorticoid exposure and all outcomes, suggesting strong relative risks, but low absolute risks, of newly-treated VTE, diabetes, and especially hypertension in children taking high-dose oral glucocorticoids.

Post-discharge venous thromboembolism after pancreatectomy for malignancy: predicting risk based on preoperative, intraoperative, and postoperative factors.
Extended chemoprophylaxis is recommended for high-risk patients following pancreatectomy for malignancy. However, quantifying risk remains difficult. In this study, the investigators sought to (a) identify factors associated with post-discharge venous thromboembolism (VTE) following pancreatectomy for malignancy and (b) develop a post-discharge VTE risk calculator to identify high-risk patients. The investigators concluded that preoperative, intraoperative, and postoperative factors were associated with post-discharge VTE following pancreatectomy for malignancy.

Use of statewide administrative data to assess clinical outcomes: a retrospective cohort study of therapeutic anticoagulation for isolated calf vein thrombosis.
Single-center comparative effectiveness studies evaluating outcomes that can occur posthospitalization may become biased if outcomes diagnosed at other facilities are not ascertained. Administrative datasets that link patients' records across facilities may improve outcome ascertainment. The purpose of this study was to determine whether use of linked administrative data significantly augmented thromboembolic outcome ascertainment. The investigators concluded that use of linked hospital administrative data augmented detection of outcomes but imperfect linkage, nonspecific diagnoses, and documentation/coding errors introduced uncertainty regarding the accuracy of outcome ascertainment.

Multi-institution evaluation of adherence to comprehensive postoperative VTE chemoprophylaxis.
The aims of this study were to: (1) measure the rate of failure to provide defect-free postoperative venous thromboembolism (VTE) chemoprophylaxis, (2) identify reasons for failure to provide defect-free VTE chemoprophylaxis, and (3) examine patient- and hospital-level factors associated with failure. The investigators concluded that in contrast to SCIP-VTE-2, their novel quality measure unmasked VTE chemoprophylaxis failures in 18% of colectomies. They found that most failures were due to patient refusals or ordering errors.

Association between surgeon practice knowledge and venous thromboembolism.
Venous thromboembolism (VTE) is the most common cause of mortality following bariatric surgery. This study aimed to determine practice patterns of VTE chemoprophylaxis among bariatric surgeons participating in a large statewide quality collaborative and compare the results of surgeon self-reported chemoprophylaxis prescription practices versus actual data from abstracted charts. They administered a 13-question survey to 66 surgeons to reveal VTE practice patterns such as medication type, dosage, timing, duration, and level of trainee involvement. They also examined the charts of all patients who had developed VTE during the study period and 15 other randomly selected patient charts per site. There was found to be a greater discordance between surgeon self-reported and actual perioperative VTE prophylaxis, but there was no significant discordance postoperatively. Greater perioperative discordance is associated with significantly increased risk of VTE.

Risk of gastrointestinal bleeding increases with combinations of antithrombotic agents and patient age.
This study investigated whether age of patient and time frame increased the risk of gastrointestinal bleeding (GIB) in elderly patients being treated with anticoagulants, antiplatelets, or a combination of both therapies. This retrospective analysis used nationwide claims data from privately insured and Medicare Advantage enrollees who received anticoagulant and/or antiplatelet agents from October 1, 2010, through May 31, 2017. The final cohort included 311,211 patients who had a primary diagnosis of atrial fibrillation, ischemic heart disease, or venous thromboembolism. There was no significant different in the proportion of patients with GIB after anticoagulant or antiplatelet monotherapy, but combination therapy increased GIB risk. Advancing age was also associated with increasing 1-year probability of FIB, especially patients older than 75 years taking combination therapy.

Using electronic health record system triggers to target delivery of a patient-centered intervention to improve venous thromboembolism prevention for hospitalized patients: is there a differential effect by race?
Venous thromboembolism (VTE) is a leading cause of preventable harm, and disparities observed in prevention practices. In this study, the investigators examined the impact of a patient-centered VTE education bundle on the non-administration of preventive prophylaxis by race. The investigators found that the patient education materials, developed collaboratively with a diverse group of patients, improved patient's understanding and the importance of VTE prevention through prophylaxis.

Pre-operative, intra-operative, and post-operative factors associated with post-discharge venous thromboembolism following colorectal cancer resection.
Venous thromboembolism (VTE) is the most common preventable cause of 30-day post-operative mortality, with many events occurring after hospital discharge. High-level evidence supports post-discharge VTE chemoprophylaxis following abdominal/pelvic cancer resection; however, some studies support a more tailored approach. The objectives of this study were to (1) identify risk factors associated with post-discharge VTE in a large cohort of patients undergoing colorectal cancer resection and (2) develop a post-discharge VTE risk calculator.

Barriers to providing VTE chemoprophylaxis to hospitalized patients: a nursing-focused qualitative evaluation.
This study analyzed barriers for administration of VTE chemoprophylaxis to hospitalized patients from nurses. Researchers conducted 14 focus group interviews with nurses from five inpatient units to assess their perceptions of barriers to administration of VTE chemoprophylaxis. Barriers included nurses’ misconceptions that patients did not require chemoprophylaxis, their uncertainty when counseling patients on the importance of chemoprophylaxis, and a lack of comparative data regarding specific refusal rates.

Cost-benefit limitations of extended, outpatient venous thromboembolism prophylaxis following surgery for Crohn's disease.
This goal of this study was to assess the cost-effectiveness of extended prophylaxis in patients with Crohn's disease after abdominal surgery. A decision tree model was used to assess cost-effectiveness and cost-per-case averted with extended-duration venous thromboembolism prophylaxis following abdominal surgery. Results showed that extended prophylaxis in patients with Crohn's disease postoperatively is not cost-effective when the cumulative incidence of posthospital thrombosis remains less than 4.9%. These findings are driven by the low absolute risk of thrombosis in this population and the considerable cost of universal treatment.

An evaluation of guideline-discordant ordering behavior for CT pulmonary angiography in the emergency department.
The aim of this study was to determine rates of and possible reasons for guideline-discordant ordering of CT pulmonary angiography for the evaluation of suspected pulmonary embolism (PE) in the emergency department. The investigators concluded that many of the guideline-discordant orders were placed for patients who presented with evidence-based risk factors for PE that are not included in the risk stratification scores. They suggest that guideline-discordant ordering may indicate that in the presence of these factors, the assessment of risk made by current scoring systems may not align with clinical suspicion.
