Room for Improvement: The Impact of Guideline-Recommended Extended Thromboprophylaxis in Patients Undergoing Abdominal Surgery for Colorectal and Anal Cancer at a Tertiary Referral Center.

BACKGROUND: Venous thromboembolism occurs in approximately 2% of patients undergoing abdominal and pelvic surgery for cancers of the colon, rectum, and anus and is considered preventable. The American Society of Colon and Rectal Surgeons recommends extended prophylaxis in high-risk patients, but there is low adherence to the guidelines. OBJECTIVE: This study aims to analyze the impact of venous thromboembolism risk-guided prophylaxis in patients undergoing elective abdominal and pelvic surgeries for colorectal and anal cancers from 2016 to 2021. DESIGN: This was a retrospective analysis. SETTING: The study was conducted at a multisite tertiary referral academic health care system. PATIENTS: Patients who underwent elective abdominal or pelvic surgery for colon, rectal, or anal cancer. MAIN OUTCOME MEASURES: Receipt of Caprini-guided venous thromboembolism prophylaxis, 90-day postoperative rate of deep vein thrombosis, pulmonary embolism, venous thromboembolism, and bleeding events. RESULTS: A total of 3504 patients underwent elective operations, of whom 2224 (63%) received appropriate thromboprophylaxis in the inpatient setting. In the postdischarged cohort of 2769 patients, only 2% received appropriate thromboprophylaxis and no thromboembolic events were observed. In the group receiving inappropriate thromboprophylaxis, at 90 days postdischarge, the deep vein thrombosis, pulmonary embolism, and venous thromboembolism rates were 0.60%, 0.40%, and 0.88%, respectively. Postoperative bleeding was not different between the 2 groups. LIMITATIONS: Limitations to our study include its retrospective nature, use of aggregated electronic medical records, and single health care system experience. CONCLUSION: Most patients in our health care system undergoing abdominal or pelvic surgery for cancers of the colon, rectum, and anus were discharged without appropriate Caprini-guided venous thromboembolism prophylaxis. Risk-guided prophylaxis was associated with decreased rates of inhospital and postdischarge venous thromboembolism without increased bleeding complications. See Video Abstract . MARGEN DE MEJORA EL IMPACTO DE LA TROMBOPROFILAXIS RECOMENDADA POR LAS DIRECTRICES EN PACIENTES SOMETIDOS A CIRUGA ABDOMINAL POR CNCER COLORRECTAL Y ANAL EN UN CENTRO DE REFERENCIA TERCIARIO: ANTECEDENTES:El tromboembolismo venoso ocurre en aproximadamente el 2% de los pacientes sometidos a cirugía abdominal y pélvica por cánceres de colon, recto y ano, y se considera prevenible. La Sociedad Estadounidense de Cirujanos de Colon y Recto recomienda una profilaxis prolongada en pacientes de alto riesgo, pero el cumplimiento de las directrices es bajo.OBJETIVO:Este estudio tiene como objetivo analizar el impacto de la profilaxis guiada por el riesgo de tromboembolismo venoso (TEV) en pacientes sometidos a cirugías abdominales y pélvicas electivas por cáncer colorrectal y anal entre 2016 y 2021.DISEÑO:Este fue un análisis retrospectivo.AJUSTE:El estudio se llevó a cabo en un sistema de salud académico de referencia terciaria de múltiples sitios.PACIENTES:Pacientes sometidos a cirugía abdominal o pélvica electiva por cáncer de colon, recto o ano.PRINCIPALES MEDIDAS DE RESULTADO:Recepción de profilaxis de tromboembolismo venoso guiada por Caprini, tasa postoperatoria de 90 días de trombosis venosa profunda, embolia pulmonar, tromboembolismo venoso y eventos de sangrado.RESULTADOS:Un total de 3.504 pacientes se sometieron a operaciones electivas, de los cuales 2.224 (63%) recibieron tromboprofilaxis adecuada en el ámbito hospitalario. En el cohorte de 2.769 pacientes después del alta, solo el 2% recibió tromboprofilaxis adecuada en la que no se observaron eventos tromboembólicos. En el grupo que recibió tromboprofilaxis inadecuada, a los 90 días después del alta, las tasas de trombosis venosa profunda, embolia pulmonar y tromboembolia venosa fueron del 0,60%, 0,40% y 0,88%, respectivamente. El sangrado posoperatorio no fue diferente entre los dos grupos.LIMITACIONES:Las limitaciones de nuestro estudio incluyen su naturaleza retrospectiva, el uso de registros médicos electrónicos agregados y la experiencia de un solo sistema de atención médica.CONCLUSIÓN:La mayoría de los pacientes en nuestro sistema de salud sometidos a cirugía abdominal o pélvica por cánceres de colon, recto y ano fueron dados de alta sin una profilaxis adecuada de TEV guiada por Caprini. La profilaxis guiada por el riesgo se asoció con menores tasas de tromboembolismo venoso hospitalario y dado de alta sin un aumento de las complicaciones de sangrado.

Risk adjusted venous thromboembolism prophylaxis following pancreatic surgery.

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.

The Impact of Caprini Guideline Indicated Venous Thromboembolism Prophylaxis in Colorectal Surgery Patients: Experience of a Single Health System.

BACKGROUND: Venous thromboembolism (VTE) is the most common cause of preventable mortality following colorectal surgery (CRS), occurring in about 2% of patients. As a result, prophylaxis including discharge chemoprophylaxis is recommended. While VTE risk assessment tools are available, the consistent adoption and utilization of these tools remains elusive. Our study objectives were to determine the utilization and impact of risk adjusted VTE prophylaxis in CRS patients. STUDY DESIGN: CRS cases performed between 1/1/2016 and 5/31/2021 were retrospectively analyzed. Caprini score and implemented VTE prophylaxis measures were determined. The primary outcome measure was receiving Caprini guideline indicated VTE prophylaxis. Secondary outcomes included VTE and bleeding. Categorical variables were compared by chi-square and Fisher's exact tests, and continuous variables by Kruskal-Wallis test. Logistic regression models were used to determine predictors of receiving appropriate VTE prophylaxis or experiencing postoperative VTE and bleeding. RESULTS: 10,422 CRS cases were analyzed and 90.6% were high risk for VTE. In-hospital appropriate prophylaxis rates in low, moderate, high, and very high-risk category patients were 91.2%, 56.1%, 61.0%, and 63.1%, respectively. Inpatient VTE was reduced by 75% in those receiving appropriate VTE prophylaxis. At discharge, 5.8% of patients received appropriate prophylaxis, in whom there were no VTE events at 30- and 90 days from discharge. Increasing Caprini score positively correlated with VTE risk in both the inpatient and discharge cohorts, but inversely correlated with the likelihood of receiving appropriate prophylaxis at discharge (OR .31, P <.0001). CONCLUSION: Caprini guideline indicated VTE prophylaxis in CRS patients reduced VTE events without increasing bleeding complications.
