EP.TU.601Improving extended venous thromboembolism prophylaxis prescription compliance at discharge for colorectal cancer resection patients

Abstract

Abstract Aims Extended venous thromboembolism prophylaxis (exVTEp) is used to reduce venous thromboembolism (VTE) incidence following colorectal cancer (CRC) resection. Within our tertiary care centre patients undergoing CRC resection should receive an electronic VTE risk assessment (eVTE) within 24 hours and exVTEp at discharge, compliance targets set at 95%. Our aim was to improve absolute compliance rates of exVTEp prescription at discharge following CRC surgery. Methods Data were collected prospectively on CRC resection patients pre and post an educational intervention for doctors during surgical induction, with posters placed in key areas highlighting discharge exVTEp importance. Patients discharged between August-December 2019 served as pre-intervention and those between December 2019-March 2020 as post-intervention cohorts. Time periods reflected junior doctor rotating periods within the country’s healthcare system thus providing more comparable data sets. The service evaluation was registered within the Trust (19-562Q) Results Of 80 pre-intervention and 40 post-intervention eligible patients: 81.25% vs. 92.68% received exVTEp at discharge, 70.19% vs. 72.34% had a valid eVTE and 32.50% vs. 36.59% had exVTEp recorded in the post-operative note. Those missing exVTEp documentation in the post-operative plan were significantly less likely to receive exVTEp at discharge with an 80% decrease in exVTEp prescription compared to patients with exVTEp documented within the post-operative note (unadjusted-OR 0.2051, 95%CI 0.0431-0.9773; p = 0.0276). Conclusions Educational and visual interventions have shown improvement in exVTEp prescription at discharge. Despite suboptimal eVTE scores true service quality in delivering exVTEp is high. The relationship between exVTEp post-operative instruction and exVTEp prescription needs further investigation.
