Association of pathologic factors with postoperative venous thromboembolism after gastrointestinal cancer surgery. J Gastrointest Surg 2024; 28:813-819. [PMID: 38553295 DOI: 10.1016/j.gassur.2024.03.002] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/10/2023] [Revised: 11/20/2023] [Accepted: 03/02/2024] [Indexed: 05/19/2024]
Abstract
BACKGROUND Venous thromboembolism (VTE) chemoprophylaxis is the standard of care after gastrointestinal (GI) cancer surgery; however, variation in risk based on pathologic factors (eg, stage and histology) is unclear. This study aimed to evaluate the association of pathologic factors with VTE after GI cancer surgery. METHODS The American College of Surgeons National Surgical Quality Improvement Program procedure targeted datasets were queried for patients who underwent colorectal, pancreatic, primary hepatic, and esophageal cancer surgery between 2017 and 2020. Disease-specific and pathologic factors associated with postoperative VTE were evaluated using multivariable logistic regression. RESULTS Among 70,934 patients who underwent GI cancer surgery, the incidence rates of 30-day postoperative VTE were 3.3% for pancreatic cancer, 3.2% for esophageal cancer, 2.7% for primary hepatic, and 1.3% for colorectal cancer. T stage was associated with VTE for colorectal cancer (T4 vs T1; odds ratio [OR], 1.79; 95% CI, 1.24-2.60), pancreatic cancer (all T stages vs T1; P < .05), and primary hepatic cancer (T4 vs T1; OR, 2.80; 95% CI, 1.55-5.08). N stage was associated with VTE for colorectal cancer (N2 vs N0; OR, 1.33; 95% CI, 1.04-1.68) and pancreatic cancer (N2 vs N0; OR, 1.36; 95% CI, 1.03-1.81). M stage was associated with VTE for colorectal cancer (OR, 1.47; 95% CI, 1.17-1.85) and esophageal cancer (OR, 2.54; 95% CI, 1.24-5.19). Histologic subtype was not associated with VTE, except for pancreatic neuroendocrine tumors vs adenocarcinoma (OR, 1.34; 95% CI, 1.03-1.74). CONCLUSION Pathologic factors were associated with higher 30-day VTE risk after GI cancer surgery. Acknowledging the association of pathologic factors on VTE is an important first step to considering a more tailored approach to chemoprophylaxis.

Neoadjuvant Chemotherapy is Associated with Increased Risk of Postoperative DVT After Distal Pancreatectomy for Pancreatic Adenocarcinoma: a NSQIP Analysis. Ann Surg Oncol 2024; 31:2873-2881. [PMID: 38151621 DOI: 10.1245/s10434-023-14763-y] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/17/2023] [Accepted: 11/25/2023] [Indexed: 12/29/2023]
Abstract
BACKGROUND Venous thromboembolism (VTE) remains a persistent source of postoperative morbidity despite prevention and mitigation efforts. Cancer, surgery, and chemotherapy are known risk factors for VTE. Existing literature suggests that neoadjuvant therapy (NAT) may contribute to increased VTE risk in the postoperative period, but few authors specifically examine this relationship in distal pancreatic adenocarcinoma (PDAC). In this study, we analyze the association of NAT and postoperative VTE in patients who underwent distal pancreatectomy (DP) for PDAC. PATIENTS AND METHODS Using the American College of Surgeons (ACS) National Surgical Quality Improvement Program (NSQIP) database, we analyzed the Procedure Targeted files for pancreatectomy from 2014 to 2020. Adults with PDAC who underwent DP were grouped by receipt of NAT. The primary outcome was the rate of deep venous thrombosis (DVT) and the secondary outcome was the rate of pulmonary embolism (PE). We performed univariate and multivariate logistic regression analysis to determine risk factors associated with postoperative DVT. RESULTS There were 4327 patients with PDAC who underwent DP. Of these, 1414 (32.7%) had NAT. Receipt of NAT was significantly associated with postoperative DVT requiring therapy (3.5% vs. 2.3%, p = 0.02), but was not associated with PE (p = 0.42). On MVA, NAT was associated with a 73% greater chance of developing postoperative DVT [odds ratio (OR) 1.73, 95% CI 1.18-2.55]. CONCLUSIONS Patients who receive NAT prior to DP for PDAC are 73% more likely to develop postoperative DVT compared with upfront resection. As NAT becomes more commonplace, these high-risk patients should be prioritized for guideline-recommended extended duration prophylaxis.

Safety of postdischarge extended venous thromboembolism prophylaxis after hepatopancreatobiliary surgery. J Gastrointest Surg 2024; 28:115-120. [PMID: 38445932 DOI: 10.1016/j.gassur.2023.11.020] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/07/2023] [Revised: 10/22/2023] [Accepted: 10/28/2023] [Indexed: 03/07/2024]
Abstract
BACKGROUND The risk of venous thromboembolism (VTE) after hepatopancreatobiliary (HPB) surgery is high. Extended postdischarge prophylaxis in this patient population has been controversial. This study aimed to examine the safety of postdischarge extended VTE prophylaxis in patients at high risk of VTE events after HPB surgery. METHODS Adult patients risk stratified as very high risk of VTE who underwent HPB operations between 2014 and 2020 at a quaternary care center were included. Patients were matched 1:2 extended VTE prophylaxis to the control group (patients who did not receive extended prophylaxis). Analyses compared the proportions of adverse bleeding events between groups. RESULTS A total of 307 patients were included: 103 in the extended prophylaxis group and 204 in the matched control group. Demographics were similar between groups. More patients in the extended VTE prophylaxis group had a history of VTE (9% vs 3%; P = .045). There was no difference in bleeding events between the extended VTE prophylaxis and the control group (6% vs 2%; P = .091). Of the 6 patients with bleeding events in the VTE prophylaxis group, 5 had gastrointestinal (GI) bleeding, and 1 had hemarthrosis. Of the 4 patients with bleeding events in the control group, 1 had intra-abdominal bleeding, 2 had GI bleeding, and 1 had intra-abdominal and GI bleeding. CONCLUSION Patients discharged with extended VTE prophylaxis after HPB surgery did not experience more adverse bleeding events compared with a matched control group. Routine postdischarge extended VTE prophylaxis is safe in patients at high risk of postoperative VTE after HPB surgery.

Abstract
BACKGROUND Venous thromboembolism (VTE) occurs in 3-11% of esophagectomy patients and is associated with increased mortality and morbidity. The use of validated VTE risk assessment tools and compliance with recommended practice guidelines remains unclear. In this study, we seek to determine the use of Caprini guideline indicated VTE prophylaxis and its effect on VTE and bleeding complications following esophagectomy. METHODS Esophagectomy cases were identified from the Mayo Clinic electronic health records. Caprini score and VTE prophylaxis regimen received were determined retrospectively. VTE prophylaxis was identified as appropriate or inappropriate based on the Caprini score and prophylaxis received preoperative, during hospitalization, and after hospital discharge. Study cohorts were compared by Pearson Chi-square test, Fisher's Exact test, Kruskal-Wallis test, and logistic regression models. Stata/MP 16.1 was used for analysis. Odds ratios and 95% confidence intervals were reported for logistic regression models. A p-value < 0.05 was considered significant. RESULTS Four hundred and fifty-six esophagectomy cases were analyzed. The median Caprini score was thirteen. Appropriate prophylaxis resulted in a 6.9-fold reduction in inpatient VTE. All 30- and 90-day post-discharge VTEs occurred in those not receiving Caprini guideline-indicated VTE prophylaxis. Inpatient, 30- and 90-day post-discharge bleeding rates were 7.68%, 0.91%, and 2.11%, respectively; however, bleeding was not increased with receipt of appropriate prophylaxis. CONCLUSION In this esophagectomy cohort, Caprini guideline indicated VTE prophylaxis resulted in reduced inpatient VTE events without increasing bleeding complications. Risk-based VTE prevention measures should be considered in this patient cohort known to be at heightened risk for postoperative VTE.

Abstract
Venous thromboembolism (VTE) occurs in 2-6% of post-hepatectomy patients and is associated with increased mortality and morbidity. The use of VTE risk assessment models in hepatectomy cases remains unclear. Our study aimed to determine the use and impact of Caprini guideline indicated VTE prophylaxis following hepatectomy. Hepatectomy cases performed during 2016-2021 were included. Caprini score and VTE prophylaxis were determined retroactively, and VTE prophylaxis was categorized as appropriate or inappropriate. The primary outcome was the receipt of appropriate prophylaxis, and secondary outcomes were postoperative VTE and bleeding. Statistical analyses included Fisher Exact test, Kruskal-Wallis, Pearson Chi-Square test, and multivariate regression models. R Statistical software was used for analysis. A p-value < 0.05 or 95% Confidence Interval (CI) excluding 1 was considered significant. A total of 1955 hepatectomy cases were analyzed. Patient demographics were similar between study cohorts. Inpatient, 30- and 90-day VTE rates were 1.28%, 0.56%, and 1.24%, respectively. By Caprini guidelines, 59% and 4.3% received appropriate in-hospital and discharged VTE prophylaxis, respectively. Inpatient VTE (4.5-fold) and mortality (9.5-fold) were lower in patients receiving appropriate prophylaxis. All discharged VTE and mortality occurred in patients not receiving appropriate prophylaxis. Inpatient, 30- and 90-day bleeding rates were 8.4%, 0.62%, and 0.68%, respectively. Appropriate prophylaxis did not increase postoperative bleeding. Increasing Caprini score inversely correlated with receiving appropriate prophylaxis (OR 0.38, CI 0.31-0.46) at discharge, and appropriate prophylaxis did not correlate with bleeding risk (OR 0.79, CI 0.57-1.12). Caprini guideline indicated prophylaxis resulted in reduced VTE complications without increasing bleeding risk.

Abstract
BACKGROUND Clinical guidelines recommend extended venous thromboembolism (VTE) prophylaxis for cancer patients after major gastrointestinal (GI) operations. However, adherence to the guidelines has been low, and the clinical outcomes not well defined. METHODS This study retrospectively analyzed a random 10 % sample of the 2009-2022 IQVIA LifeLink PharMetrics Plus database, an administrative claims database representative of the commercially insured population of the United States. The study selected cancer patients undergoing major pancreas, liver, gastric, or esophageal surgery. The primary outcomes were 90-day post-discharge VTE and bleeding. RESULTS The study identified 2296 unique eligible operations. During the index hospitalization, 52 patients (2.2 %) experienced VTE, 74 patients (3.2 %) had postoperative bleeding, and 140 patients (6.1 %) had a hospital stay of at least 28 days. The remaining 2069 operations comprised 833 pancreatectomies, 664 hepatectomies, 295 gastrectomies, and 277 esophagectomies. The median age of the patients was 49 years, and 44 % were female. Extended VTE prophylaxis prescriptions were filled for 176 patients (10.4 % for pancreas, 8.1 % for liver, 5.8 % for gastric cancer, and 6.5 % for esophageal cancer), and the most used agent was enoxaparin (96 % of the patients). After discharge, VTE occurred for 5.2 % and bleeding for 5.2 % of the patients. The findings showed no association of extended VTE prophylaxis with post-discharge VTE (odds ratio [OR], 1.54; 95 % confidence interval [CI], 0.81-2.96) or bleeding (OR, 0.72, 95 % CI, 0.32-1.61). CONCLUSIONS The majority of the cancer patients undergoing complex GI surgery did not receive extended VTE prophylaxis according to the current guidelines, and their VTE rate was not higher than for the patients who received it.

Abstract
BACKGROUD/PURPOSE Venous thromboembolism, including deep vein thrombosis (DVT) and pulmonary embolism (PE), is an important complication in patients who underwent open hepatic surgery as well as other major upper abdominal surgery. This study aims to investigate the occurrence of postoperative DVT without pharmacological thromboprophylaxis in such cohorts in Taiwan. METHODS This is a prospective, cross-sectional cohort study conducted from March 2010 to December 2011. Patients who underwent major upper abdominal surgery, including open hepatectomy, were enrolled. Color duplex compression ultrasonography (CUS) was used to detect DVT. Symptomatic PE was excluded if there were no suggestive respiratory symptoms or sudden death. Relevant clinicopathological and surgical information of each patient was collected and analyzed. RESULTS 195 patients (118 male and 77 female) were enrolled, with a median age of 63.6 years. The majority (169/195, 88.7%) were treated for active malignancy. Totally 147 patients received open hepatectomy. Only one asymptomatic and distal postoperative DVT event was identified by CUS, which occurred on a 73-year-old female patient who received a left lateral segmental hepatectomy for removing the advanced hepatocellular carcinoma (pathologic stage, T3aN0M0). No cases of symptomatic PE or sudden death were observed. No correlation between DVT and precipitating factor was demonstrated in our cohort. CONCLUSION Without pharmacological thromboprophylaxis, a low rate of postoperative DVT among patients undergoing open hepatectomy (0.7%, 1/147) or major upper abdominal surgery (0.5%, 1/195) in Taiwan was reported. A distinctively regional role of pharmacological thromboprophylaxis for hepatic surgery was also suggested by our data.

Abstract
INTRODUCTION Extended venous thromboembolism prophylaxis (eVTEp) is recommended for select patients who have undergone major abdominopelvic surgery to prevent postdischarge venous thromboembolism (pdVTE). Criteria for selection of these patients are untested for this purpose and may be ineffective. To address this gap, we investigated the effectiveness of eVTEp on pdVTE rates. METHODS A retrospective cohort study of patients undergoing abdominopelvic surgery from January 2016 to February 2020 was performed using data from the Michigan Surgical Quality Collaborative. pdVTE was the main outcome. Our exposure variable, eVTEp, was compared dichotomously. Length of stay (LOS) was compared categorically using clinically relevant groups. Age, race, cancer occurrence, inflammatory bowel disease, surgical approach, and surgical time were covariates among other variables. Descriptive statistics, propensity score matching, and multivariable logistic regression were performed to compare pdVTE rates. RESULTS A total of 45,637 patients underwent abdominopelvic surgery. Of which, 3063 (6.71%) were prescribed eVTEp. Two hundred eighty-five (0.62%) had pdVTE. Of the 285, 59 (21%) patients received eVTEp, while 226 (79%) patients did not. After propensity score matching, multivariable logistic regression analysis showed pdVTE was associated with eVTEp and LOS of 5 d or more (P < 0.001). eVTEp was not associated with LOS. Further analysis showed increased risk of pdVTE with increasing LOS independent of prescription of eVTEp based on known risk factors. CONCLUSIONS pdVTE was associated with increasing LOS but not with other VTE risk factors after propensity score matching. Current guidelines for eVTEp do not include LOS. Our findings suggest that LOS >5 d should be added to the criteria for eVTEp.

Abstract
BACKGROUND Postoperative venous thromboembolism (VTE) is associated with significant morbidity. Evidence from other surgical specialties demonstrate inadequate use of extended VTE prophylaxis following cancer surgery. While guidelines recommend extended VTE prophylaxis for patients undergoing surgery for colorectal cancer (CRC), it is unknown to what extent colon and rectal surgeons adhere to these recommendations. METHODS An 18-question online survey was distributed to all surgeon members of the American Society of Colon and Rectal Surgeons (ASCRS). The survey was designed to capture knowledge, attitudes, and practices regarding ASCRS VTE prevention guidelines. Questions were also designed to elucidate barriers to adopting these guidelines. RESULTS The survey was distributed to 2,316 ASCRS-member surgeons and there were 201 complete responses (8.7% response rate). Most respondents (136/201, 68%) reported that they were familiar with ASCRS VTE prevention guidelines and used them to guide their practice. Extended VTE prophylaxis was reported to be routinely prescribed by the majority of surgeons following CRC resection (109/201, 54%), with an additional 27% reporting selective prescribing (55/201). The most frequently reported reasons for not prescribing extended VTE chemoprophylaxis following CRC resection included patient compliance and insurance/copay issues. CONCLUSION Most ASCRS-member surgeon respondents reported that they are familiar with ASCRS VTE prevention guidelines, though only 54% surgeons reported routinely prescribing extended VTE prophylaxis following CRC surgery. Patient compliance and insurance issues were identified as the most common barriers. Targeted interventions at the surgeon, patient, and payer level are required to increase the use of extended VTE prophylaxis following CRC resection.

Abstract
This study analyzes pancreatectomy cases performed between 2016 and 2021 to determine the impact of using Caprini guideline indicated VTE prophylaxis on VTE and bleeding complications. This is a retrospective study of cases performed in a single academic health care system, in which Caprini score and VTE prevention measures were determined retroactively and prevention practices binarized as appropriate or not appropriate. Univariate and multivariate analyses were performed of 1,299 pancreatectomy case. Most patients were stratified as high risk for postoperative VTE. Receiving appropriate VTE prophylaxis during admission was associated with a 3-fold reduction in VTE complications (0.82% vs. 2.64%, p=0.01) without increasing bleeding complications. All VTE complications occurring with 30-day (1.2%) and 90-day (2.7%) from hospital discharged occurred in those not receiving appropriate prophylaxis, and discharged bleeding complications were also not associated with receivng appropriate discharged VTE prophylaxis. The findings our the study are significant as it highlights the ongoing need for standardization in VTE risk assessment and prevention measures to increase compliance to risk adjusted VTE prevention practice guidelines, thus reducing preventable VTE complications and potentially associated morbidity and mortality.

Fourteen years of pancreatic surgery for malignancy among ACS-NSQIP centers: Trends in major morbidity and mortality. Surgery 2022; 172:708-714. [PMID: 35537881 DOI: 10.1016/j.surg.2022.03.030] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/30/2022] [Revised: 03/14/2022] [Accepted: 03/21/2022] [Indexed: 02/07/2023]
Abstract
BACKGROUND The American College of Surgeons National Surgical Quality Improvement Program was established to help participating hospitals track and report surgical complications with the goal of improving surgical care. We sought to determine whether this has led to improvements in surgical outcomes for pancreatic malignancies. METHODS Patients with pancreatic malignancies who underwent surgical resection were identified from the American College of Surgeons National Surgical Quality Improvement Program database (2006-2019). Thirty-day postoperative major morbidity and mortality were analyzed by year. Major morbidity included organ and deep surgical site infection, venous thromboembolism, cardiac event, pneumonia, acute renal failure, sepsis, and respiratory failure. RESULTS Of the 28,888 patients identified, 51% were male, the median age was 68, 74.3% underwent a pancreaticoduodenectomy, and 25.7% underwent a distal pancreatectomy. Among patients who underwent a pancreaticoduodenectomy, there was a significant increase in major morbidity (annual percent change 0.77, P = .012) driven by increases in organ space surgical site infection (annual percent change 3.52, P < .001) and venous thromboembolism (annual percent change 4.72, P = .005). However, there was a decrease in postoperative mortality (annual percent change -4.58, P = .001). For distal pancreatectomy patients, there was no change in rates of overall major morbidity (annual percent change -1.35, P = .08) or mortality (annual percent change -3.21, P = .25). CONCLUSION Although major morbidity and mortality have not significantly changed for distal pancreatectomy patients, mortality has steadily decreased for patients undergoing pancreaticoduodenectomy, despite an increase in major morbidity. Whether this trend reflects a change in patient selection, an increase in detection of postoperative morbidities and/or an improvement in mitigation of these morbidities warrants further study.

Post-hepatectomy venous thromboembolism: a systematic review with meta-analysis exploring the role of pharmacological thromboprophylaxis. Langenbecks Arch Surg 2022; 407:3221-3233. [PMID: 35881311 DOI: 10.1007/s00423-022-02610-9] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/27/2022] [Accepted: 07/12/2022] [Indexed: 10/16/2022]
Abstract
PURPOSE Patients undergoing hepatectomy are at moderate-to-high risk of venous thromboembolism (VTE). This study critically examines the efficacy of combining pharmacological (PTP) and mechanical thromboprophylaxis (MTP) versus only MTP in reducing VTE events against the risk of hemorrhagic complications. METHODS A systematic review of major reference databases was undertaken, and a meta-analysis was performed using common-effects model. Risk of bias assessment was performed using Newcastle-Ottawa scale. Trial sequential analysis (TSA) was used to assess the precision and conclusiveness of the results. RESULTS 8 studies (n = 4238 patients) meeting inclusion criteria were included in the analysis. Use of PTP + MTP was found to be associated with significantly lower VTE rates compared to only MTP (2.5% vs 5.3%; pooled RR 0.50, p = 0.03, I2 = 46%) with minimal type I error. PTP + MTP was not associated with an increased risk of hemorrhagic complications (3.04% vs 1.9%; pooled RR 1.54, p = 0.11, I2 = 0%) and had no significant impact on post-operative length of stay (12.1 vs 10.8 days; pooled MD - 0.66, p = 0.98, I2 = 0%) and mortality (2.9% vs 3.7%; pooled RR 0.73, p = 0.33, I2 = 0%). CONCLUSION Despite differences in the baseline patient characteristics, extent of hepatectomy, PTP regimens, and heterogeneity in the pooled analysis, the current study supports the use of PTP in post-hepatectomy patients (grade of recommendation: strong) as the combination of PTP + MTP is associated with a significantly lower incidence of VTE (level of evidence, moderate), without an increased risk of post-hepatectomy hemorrhage (level of evidence, low).

Abstract
IMPORTANCE Venous thromboembolism (VTE) is a major cause of preventable morbidity and mortality after cancer surgery. Venous thromboembolism events that are significant enough to require hospital readmission are potentially life threatening, yet data regarding the frequency of these events beyond the 30-day postoperative period remain limited. OBJECTIVE To determine the rates, outcomes, and predictive factors of readmissions owing to VTE up to 180 days after complex cancer operations, using a national data set. DESIGN, SETTING, AND PARTICIPANTS A retrospective cohort study of the 2016 Nationwide Readmissions Database was performed to study adult patients readmitted with a primary VTE diagnosis. Data obtained from 197 510 visits for 126 104 patients were analyzed. This was a multicenter, population-based, nationally representative study of patients who underwent a complex cancer operation (defined as cystectomy, colectomy, esophagectomy, gastrectomy, liver/biliary resection, lung/bronchus resection, pancreatectomy, proctectomy, prostatectomy, or hysterectomy) from January 1 through September 30, 2016, for a corresponding cancer diagnosis. EXPOSURES Readmission with a primary diagnosis of VTE. MAIN OUTCOMES AND MEASURES Proportion of 30-, 90-, and 180-day VTE readmissions after complex cancer surgery, factors associated with readmissions, and outcomes observed during readmission visit, including mortality, length of stay, hospital cost, and readmission to index vs nonindex hospital. RESULTS For the 126 104 patients included in the study, 30-, 90-, and 180-day VTE-associated readmission rates were 0.6% (767 patients), 1.1% (1331 patients), and 1.7% (1449 of 83 337 patients), respectively. A majority of patients were men (58.7%), and the mean age was 65 years (SD, 11.5 years). For the 1331 patients readmitted for VTE within 90 days, 456 initial readmissions (34.3%) were to a different hospital than the index surgery hospital, median length of stay was 5 days (IQR, 3-7 days), median cost was $8102 (IQR, $5311-$10 982), and 122 patients died (9.2%). Independent factors associated with readmission included type of operation, scores for severity and risk of mortality, age of 75 to 84 years (odds ratio [OR], 1.30; 95% CI, 1.02-1.78), female sex (OR, 1.23; 95% CI, 1.11-1.37), nonelective index admission (OR, 1.31; 95% CI, 1.03-1.68), higher number of comorbidities (OR, 1.30; 95% CI, 1.06-1.60), and experiencing a major postoperative complication during the index admission (OR, 2.08; 95% CI, 1.85-2.33). CONCLUSIONS AND RELEVANCE In this cohort study, VTE-related readmissions after complex cancer surgery continued to increase well beyond 30 days after surgery. Quality improvement efforts to decrease the burden of VTE in postoperative patients should measure and account for these late VTE-related readmissions.

Abstract
To assess the knowledge, attitudes, and practices regarding venous thromboembolism (VTE) prophylaxis among medical staff at a tertiary hospital in China.A self-administered web-based survey was completed by medical staff, and data about respondent knowledge, attitudes, and practices regarding VTE prophylaxis were gathered and analyzed with chi-square tests, using a 95% significance level.Of the 2079 medical staff invited to participate in the survey, a total of 2042 (including 921 clinicians and 1121 nurses) responded. The overall rate of correct responses to knowledge items was 57.6%; the rate was 60.1% for clinicians and 55.4% for nurses (P < .001). The median affirmative ("strongly agree"/"agree") rate for attitude items was 99.0% (range, 83.2%-99.4%). Medical staff members were most commonly concerned about the possibility of a financial penalty when a patient could not be treated with VTE prophylaxis (49.4%). Low levels of knowledge and participation of medical staff were identified most commonly as difficulties involved in VTE prophylaxis (48.5%). The median affirmative response rate for practice items was 58.2% (range, 51.1%-68.3%). All affirmative response rates for practice items were significantly higher for nurses than for clinicians (all P < .001).Although the overall attitude toward VTE prophylaxis was positive, the knowledge level was poor, especially among nurses, and the rate of affirmative responses regarding practices was low, especially among clinicians. Medical institutions should improve staff training regarding VTE prophylaxis, and medical staff should be encouraged to actively engage in VTE prophylaxis.

Abstract
BACKGROUND AND OBJECTIVES Despite quality evidence supporting postoperative extended venous thromboembolism prophylaxis (eVTEp) following abdominopelvic cancer surgery, baseline use of eVTEp at our institution was 3%. Our project aim was to improve the proportion of patients prescribed eVTEp following surgery for gynecologic, hepatobiliary, and colorectal cancers by a 30% absolute increase. METHODS We performed an interrupted time series study using quality improvement methodology. Postoperative order sets, pre-printed prescriptions, process checklists, and multimodal education were introduced. Process and outcome data were collected and analyzed on statistical process control charts. RESULTS We included 324 patients with gynecologic and hepatobiliary cancers. Despite efforts to include them, the colorectal team did not participate. The monthly mean order set-use was 58% (SD = 14%), by specialty: gynecology 79%, hepatobiliary 47%. The proportion of patients prescribed eVTEp increased from 3% to 70% (SD = 14%). The target goal was surpassed and sustained by both cohorts. Patient compliance was 73% (n = 117/160, SD = 16%). Of those who stopped eVTEp early, 45% (n = 14/31) objected because of the injectable nature. Bleeding events were infrequent (0.6%, n = 2/324). CONCLUSIONS Three process changes and multimodal education resulted in a significant increase in eVTEp use. Failure to identify improvement champions limited project expansion to colorectal patients. Patient compliance was largely limited by the injectable nature of the medication.

Incidence and Risk Factors of Venous Thromboembolism Following Hepatectomy for Colorectal Metastases: A Population-Based Retrospective Cohort Study. World J Surg 2021; 46:180-188. [PMID: 34591148 DOI: 10.1007/s00268-021-06316-9] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 09/04/2021] [Indexed: 10/20/2022]
Abstract
BACKGROUND Incidence of venous thromboembolism (VTE) following hepatectomy for colorectal cancer (CRC) metastases is unclear. These patients may represent a vulnerable population due to increased tumour burden. We aim to identify the risk of VTE development in routine clinical practice among patients with resected CRC liver metastases, the associated risk factors, and its impact on survival. METHODS We conducted a population-based retrospective cohort study of Ontario patients undergoing hepatectomy for CRC metastases between 2002 and 2009 using linked universal healthcare databases. Multivariable logistic regression was used to estimate the association between patient characteristics and VTE risk at 30 and 90-days after surgery. Cox proportional-hazards regression was used to estimate the association between VTE and adjusted cancer specific (CSS) and overall survival (OS). RESULTS 1310 patients were included with a mean age of 63 ± 11. 62% were male. 51% had one metastatic deposit. Major hepatectomy occurred in 64%. VTE occurred in 4% within 90 days of liver resection. Only longer length of stay was associated with VTE development (OR 6.88 (2.57-18.43), p <0.001 for 15-21 days versus 0-7 days). 38% of VTEs were diagnosed after discharge, comprising 1.52% of the total cohort. VTE was not associated with inferior CSS or OS. CONCLUSIONS Risk of VTE development in this population is similar to those undergoing hepatectomy for other indications, and to the risk following other cancer site resections where post-operative extended VTE prophylaxis is currently recommended. The number of VTEs occurring after discharge suggests there may be a role for extended VTE prophylaxis.

Risk of venous thromboembolism in patients with elevated INR undergoing hepatectomy: an analysis of the American college of surgeons national surgical quality improvement program registry. HPB (Oxford) 2021; 23:1008-1015.

Abstract
BACKGROUND Patients undergoing hepatectomy can have elevated INR and may have venous thromboembolism (VTE) prophylaxis withheld as a result. We sought to examine the association between preoperative INR elevation and VTE following hepatectomy. METHODS Hepatectomies captured in the American College of Surgeons National Surgical Quality Improvement Program registry between 2007 and 2016 were analyzed. Univariable and multivariable models examined the effect of incremental increases in preoperative INR on 30-day VTE, perioperative transfusion, serious morbidity, and mortality, adjusting for potential confounders. RESULTS We included 25,220 elective hepatectomies (62.4% partial lobectomies, 10.1% left hepatectomies, 18.6% right hepatectomies, 9.2% trisegmentectomies). The median age of the patients was 60 years and 49% were male. INR was elevated in 3089 patients (12.2%): 1.1-1.2 in 8.1%, 1.2-1.4 in 3.3%, and 1.4-2.0 in 0.9%. Incremental elevations in INR were independently associated with increasing risk for postoperative VTE [odds ratio (OR) 1.15, 95% confidence intervals 1.01-1.31], perioperative transfusion [OR 1.35 (1.28-1.43)], serious morbidity [OR 1.35 (1.28-1.43)], and mortality [OR 1.76 (1.56-1.98)]. CONCLUSION Elevation in preoperative INR was counter-intuitively associated with increased risk of both VTE and perioperative transfusion following hepatectomy. The role of perioperative thromboprophylaxis warrants further investigation to determine optimal care in patients with elevated preoperative INR.

Abstract
BACKGROUND Post-discharge venous thromboembolism (VTE) chemoprophylaxis decreases VTEs following cancer surgery, however identifying high-risk patients remains difficult. Our objectives were to (1) identify factors available at hospital discharge associated with post-discharge VTE following hepatectomy for malignancy and (2) develop and validate a post-discharge VTE risk calculator to evaluate patient-specific risk. METHODS Patients who underwent hepatectomy for malignancy from 2014 to 2017 were identified from the ACS NSQIP hepatectomy procedure targeted module. Multivariable logistic regression identified factors associated with post-discharge VTE. A post-discharge VTE risk calculator was constructed, and predicted probabilities of post-discharge VTE were calculated. RESULTS Among 11 172 patients, 95 (0.9%) developed post-discharge VTE. Post-discharge VTE was associated with obese BMI (OR 2.29 vs. normal BMI [95%CI 1.31-3.99]), right hepatectomy/trisegmentectomy (OR 1.63 vs. partial/wedge [95%CI 1.04-2.57]), and several inpatient postoperative complications: renal insufficiency (OR 5.29 [95%CI 1.99-14.07]), transfusion (OR 1.77 [95%CI 1.12-2.80]), non-operative procedural intervention (OR 2.97 [95%CI 1.81-4.86]), and post-hepatectomy liver failure (OR 2.22 [95%CI 1.21-4.08]). Post-discharge VTE risk ranged from 0.3% to 30.2%. Twenty iterations of 10-fold cross validation identified internal validity. CONCLUSIONS Risk factors from all phases of care, including inpatient complications, are associated with post-discharge VTE following hepatectomy. Identifying high-risk patients may allow for personalized risk-based post-discharge chemoprophylaxis prescribing.

Abstract
BACKGROUND Venous thromboembolism (VTE) is a common, high-mortality condition among surgical cancer patients. Comprehensive analyses of VTE among postoperative cancer patients are lacking. We sought to determine the association between readmission with VTE and primary cancer diagnosis in a nationwide database at 90- and 180-days after initial admission for cancer surgery. METHODS Retrospective analyses of post-surgical cancer patients readmitted with VTE were conducted using data from the Nationwide Readmissions Database (NRD) (2010-2014). Multivariate logistic regression models adjusting for patient and hospital factors were used to determine 90- and 180-day readmission rates for VTE by cancer type. Patient factors associated with readmission were also examined. RESULTS Among a sample of 535,992 cancer patients undergoing tumor resection, readmission with VTE occurred in 1.7% within 90-days and 2.3% within 180-days. Patients readmitted for VTE experienced a 7% mortality rate. Highest rates of VTE readmission at 180 days occurred in brain (6.7%), pancreatic (5.6%), and respiratory and intrathoracic cancers (4.4%). Using pancreatic cancer as reference, brain cancer had the highest odds of readmission at 180-days (OR 2.23, 95% CI [1.95-2.55]). CONCLUSION Readmission with VTE among surgical cancer patients occurred in 2.3% of patients within 180 days. Among cancer types, primary brain cancer was independently associated with readmission with VTE.

BACKGROUND In this study, we sought to assess knowledge, attitudes, and behaviors regarding venous thromboembolism (VTE) prophylaxis among clinicians at a tertiary hospital of China. METHODS An electronic questionnaire was sent to clinicians to gather information regarding demographic data (5 items), knowledge about VTE prophylaxis (21 items), behaviors regarding VTE prophylaxis (8 items), and attitudes regarding VTE prophylaxis (7 items). Answers of "strongly agree" and "agree" on the behaviors and attitude items were defined as affirmative responses. Clinicians were also asked to provide suggestions regarding VTE prophylaxis. RESULTS A total of 867 clinicians were included in this study. The overall correct response rate for knowledge items was 60.9%. The median affirmative response rate for behavior items was 48.6% (range 29.5-80.3%), and the median affirmative response rate for attitude items was 98.7% (range 96.9-99.3%). Clinicians were most concerned about the adverse effects triggered by chemical VTE prophylaxis (79.5%) and possibility of a financial penalty when a patient could not be treated with VTE prophylaxis (72.3%). Low patient compliance and low level of clinician knowledge and participation were identified most commonly as difficulties involved in VTE prophylaxis. A total of 78 suggestions were collected; these suggestions generally focused on improving the quality and frequency of staff training (n = 24) and enhancing learning opportunities (n = 22). CONCLUSIONS Although the clinicians' overall attitude toward VTE prophylaxis was positive, the knowledge level was relatively poor, and the rate of affirmative responses regarding behaviors was low. Medical institutions should improve clinician training regarding VTE prophylaxis.

Post-discharge venous thromboembolism after pancreatectomy for malignancy: Predicting risk based on preoperative, intraoperative, and postoperative factors. J Surg Oncol 2020; 122:675-683.

Abstract
BACKGROUND AND OBJECTIVES Extended chemoprophylaxis is recommended for high-risk patients following pancreatectomy for malignancy. However, quantifying risk remains difficult. We 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. METHODS Patients who underwent pancreatectomy for malignant histology from 2014 to 2018 were identified from the ACS NSQIP pancreatectomy procedure targeted dataset. Preoperative, intraoperative, and postoperative factors known at hospital discharge were evaluated for association with post-discharge VTE via multivariable logistic regression. A post-discharge VTE risk calculator was developed and validated. RESULTS Of 19 340 analyzed patients, 280 (1.5%) developed post-discharge VTE. Post-discharge VTE was associated with increasing body mass index (BMI; eg, morbidly obese BMI odds ratio [OR]: 1.99 [95% confidence interval {CI}: 1.30-3.02] vs normal BMI), procedure type (distal pancreatectomy OR: 1.47 [95% CI: 1.02-2.12] vs pancreaticoduodenectomy), pancreatic fistula (OR: 1.59 [95% CI: 1.19-2.13]) and delayed gastric emptying (OR: 1.81 [95% CI: 1.29-2.52]). Patients' predicted probability of post-discharge VTE ranged from 0.7% to 9.0%. Twenty iterations of 10-fold cross-validation demonstrated internal validity. CONCLUSIONS Preoperative, intraoperative, and postoperative factors were associated with post-discharge VTE following pancreatectomy for malignancy. This post-discharge VTE risk calculator allows for quantification of individual post-discharge VTE risk, which ranged from 0.7% to 9.0%.

Abstract
BACKGROUND The risk of venous thromboembolism (VTE) persists beyond hospitalization in surgical patients, yet post-hospital discharge chemoprophylaxis regimens are not common. The purpose of this study is to systematically review the literature regarding extended-duration (post-hospital discharge) venous thromboembolism chemoprophylaxis and to determine whether it is warranted in high-risk surgical patients, as determined by its safety and efficacy. METHOD We searched four online databases for articles evaluating extended-duration (post-hospital discharge) VTE chemoprophylaxis regimens in surgical patients between the years January 2000 and February 2020. The Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines were used. GRADE methodology and the Cochrane Risk of Bias Assessment Tool for Randomized Controlled Trials were used to grade the quality of evidence and assess risk of bias. RESULTS Nineteen studies with 10,544 patients were analyzed. The duration for extended-duration VTE chemoprophylaxis ranged from 7 to 42 days. In our study cohort, high-risk patients not prescribed extended-duration VTE chemoprophylaxis had a mean VTE incidence rate of 12.23%, while patients receiving 28-30 days of chemoprophylaxis had a mean VTE incidence rate of 4.37% (p = 0.006). The risk of bleeding events did not correlate with the duration of chemoprophylaxis. CONCLUSION Extended-duration VTE chemoprophylaxis in high-risk surgical patients decreased the incidence of thrombotic complications without increasing the risk of bleeding events. Further research is needed to establish guidelines for the optimal duration of VTE chemoprophylaxis in high-risk surgical patients. LEVEL OF EVIDENCE III.
