ABSTRACT

INTRODUCTION: The prediction of complications before gastric surgery is of utmost importance in shared decision making and proper counseling of the patient in order to minimize postoperative complications. Our aim was to evaluate the predictive validity of American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP) risk calculator in gastric cancer patients who underwent gastrectomy.

METHODS: Preoperative assessment data of 432 patients were retrospectively reviewed and manually entered into the calculator. The accuracy of the calculator was evaluated using Pearson's chi-squared test, C-statistic, Brier score, and Hosmer-Lemeshow test.

RESULTS: The lowest Brier scores were observed in urinary tract infection, renal failure, venous thromboembolism, pneumonia, and cardiac complications. Best results were obtained for predicting sepsis, discharge to rehabilitation facility, and death (low Brier scores, C-statistic >.7, and Hosmer-Lemeshow P > .05).

CONCLUSION: The calculator had a strong performance in predicting sepsis, discharge to the rehabilitation facility, and death. However, it performed poor in predicting the most commonly observed events (any or serious complication and surgical site infection).

Venous thromboembolism prevention in cancer care: implementation strategies to address underuse

Res Pract Thromb Haemost. 2023 Aug 20;7(7):102173. doi: 10.1016/j.rpth.2023.102173. eCollection 2023 Oct.

ABSTRACT

BACKGROUND: Evidenced-based interventions have been developed to prevent venous thromboembolism (VTE) in ambulatory patients with cancer, including VTE-risk assessment for all patients and targeted primary thromboprophylaxis for high-risk patients. Despite supportive evidence and recommendations, oncologists rarely assess VTE risk or provide primary prophylaxis. Our previous work identified barriers and facilitators to using VTE prevention interventions in oncology practice.

OBJECTIVES: To identify potential strategies that address the identified barriers and leverage facilitators to achieve successful implementation of evidence-based interventions for VTE prevention in oncology practice.

METHODS: We used the Implementation Research Logic Model, an implementation science framework, to map the relationships among barriers and facilitators, feasible and effective implementation strategies, and implementation and clinical outcomes that will be used to evaluate the implementation strategies.

RESULTS: We identified 12 discrete implementation strategies (eg, conducting clinician education and training and staged implementation scale-up) that address barriers and leverage facilitators through their mechanisms of action (eg, increased clinician awareness of evidence and targeting the highest effectiveness). We identified key implementation (eg, penetration, adoption, acceptability, fidelity, appropriateness, and sustainability), system (eg, integration of VTE-risk assessment into clinical workflow), and clinical (eg, lower VTE rates) outcomes targeted by the selected strategies.

CONCLUSION: Using the Implementation Research Logic Model framework and building on our knowledge of barriers and facilitators, we identified implementation strategies and important outcomes to evaluate these strategies. We will use these results to test and measure the strategies to improve the uptake of evidence-based recommendations for VTE prevention in oncology practice.

Tissue factor pathway inhibitor is associated with risk of venous thromboembolism and all-cause mortality in patients with cancer

ABSTRACT

Venous thromboembolism (VTE) is a common complication in patients with cancer. Data on the role of natural inhibitors of coagulation for occurrence of cancerassociated VTE are limited, thus, we investigated the association of tissue factor pathway inhibitor (TFPI) with risk of VTE and all-cause mortality in patients with cancer. Total TFPI antigen levels were measured with a commercially available ELISA in patients included in the Vienna Cancer and Thrombosis Study, a prospective observational cohort study with the primary outcome VTE. Competing risk analysis and Cox regression analysis were performed to explore the association of TFPI levels with VTE and all-cause mortality. TFPI was analyzed in 898 patients (median age: 62 years [interquartile range, IQR: 53-68]; 407 [45%] women). Sixtyseven patients developed VTE and 387 died (24-month cumulative risk: 7.5% and 42.1%, respectively). Patients had median TFPI levels at study inclusion of 56.4ng/mL (IQR: 45.7-70.0), with highest levels in tumor types known to have a high risk of VTE (gastroesophageal-, pancreatic and brain-cancer: 62.0ng/mL [IQR: 52.0-75.0]). In multivariable analysis adjusting for age, sex, cancer type and stage, TFPI levels were associated with VTE risk (SHR per doubling: 1.63, 95%CI: 1.03-2.57). When patients with high and intermediate/low VTE risk were analyzed separately, the association remained independently associated in the high risk group only (SHR: 2.63, 95%CI: 1.40-4.94). TFPI levels were independently associated with all-cause mortality (HR: 2.36, 95%CI: 1.85-3.00). In cancer patients increased TFPI levels are associated with VTE risk, specifically in patients with high risk tumor types, and with all-cause mortality.
