Abstract
Abstract Aim Venous thromboembolism (VTE) is a life-threatening complication in cancer patients undergoing surgery. NICE recommends VTE-prophylaxis to 28days for patients undergoing major abdominal cancer surgery. The efficacy of in-hospital VTE-prophylaxis is well-documented, but the optimal duration of postoperative VTE-prophylaxis remains controversial. Patients undergoing oesophagogastric cancer surgery have a higher risk of VTE due to suboptimal oral intake, dehydration, need for adjuvant and neoadjuvant chemotherapy. Hence in 2014, extended VTE-prophylaxis to 28days from hospital discharge (HD) was adopted as a departmental policy. This study aims to evaluate its effectiveness, prescribing compliance and safety. Method This is a 10-year retrospective study from July 2012-2022. All patients who underwent cardio-oesophagectomy or gastrectomy for oesophagogastric cancers were included. Patients who died during the index admission, benign oesophagogastric surgery including excision of GIST, and central line associated VTE were excluded. The primary outcome is prescribing compliance with 28-day VTE prophylaxis from HD. The secondary outcome includes the incidence of VTE and bleeding complications requiring hospital readmission within 28days from HD. Results 582 patients were included in our study. Since 2014, 423/490patients (86.3%) have been discharged with 28days VTE-prophylaxis from HD compared to pre-2014 (13/92patients,14.1%). There was a statistically significant difference in improving prescribing compliance following the introduction of this policy (p<0.05). No patient was readmitted due to bleeding complications. Only 1 patient (1/582,0.17%) developed VTE within 28days from HD. Conclusions We recommend extending VTE-prophylaxis for 28days from hospital discharge for all patients undergoing oesophagogastric cancer surgery. This improves prescribing compliance, reduces the incidence of post-discharge VTE and is safe.
